Abstract
Description
Technical Field
[0001] The invention relates to the technical field of pillows, and in particular to a manufacturing process of an integrated foaming magnetic health-care pillow. Background Art
[0002] The existing foam pillows are all foamed through molds. The existing foam pillow technology is basically to make a fuss about the materials, the conditions of the production process, and the improvement of the components. There are relatively few steps designed for structural improvement in the foaming process. Of course, there are still many existing processes.
[0003] For example, the Chinese patent with application number 202410575166.X discloses a preparation process for a memory foam pillow based on agarwood for calming the nerves and helping sleep. Technical problem: During the use of memory foam pillows, because ordinary memory foam pillows usually only provide basic comfort and support, they cannot play an auxiliary role in calming the nerves and helping sleep, and cannot relax the body and mind and solve the problem of sleep quality. Technical solution: A preparation process for a memory foam pillow based on agarwood for calming the nerves and helping sleep, the steps are as follows: Step 1: Prepare raw materials, Step 2: Grind agarwood, Step 3: Prepare polyurethane foam material, Step 4: Mix raw materials, Step 5: Add auxiliary materials, Step 6: Stirring and heating, Step 7: Foaming and molding, Step 8: Cooling and curing, Step 9: Packaging and inspection. Through the intervention of fragrance ingredients, the pillow emits a faint fragrance of agarwood, making people rest more comfortably and sleep better.
[0004] The above-mentioned process has little effect on the change of the internal structure, and hard structures such as magnets cannot be placed directly on the pillow during the foaming process. The current process is to place magnetic materials on the pillow after the pillow is foamed and formed by grooving. For example, a Chinese patent application number 201810598191.4 discloses a magnetic therapy health pillow with an alarm function that is convenient for placing a mobile phone, comprising a pillow core and a pillow base. The pillow core is made of natural latex material or polyurethane foam plastic, and magnets with magnetic therapy function are evenly arranged on the surface of the pillow core. The pillow base is made of a plastic molding process, and the shape of the pillow base is a saddle shape with high ends and a low middle, and the interior is hollow. The low-lying part in the middle of the pillow base is used to place the pillow core, and the raised parts at both ends of the pillow base are provided with a clock and a clock setting disk, which are connected to the clock and the clock setting disk by wires. A regularly shaped mobile phone placement grid is provided at each end of the pillow base for placing a mobile phone. This pillow is a pillow that places magnets by slotting the surface. However, this simple surface slotting structure for placing magnets has low structural stability and is prone to damage to the pillow body itself. At the same time, the surface magnetic field strength of the magnet cannot be very high, which is easy to cause interference, resulting in magnetic attraction and magnet flipping, pillow body deformation, etc., and it will also be magnetized, which is not comfortable to use and the magnet is easy to fall off when cleaning.
[0005] Therefore, the structure and process of the existing foam pillows do not have a more scientific and reasonable setting for the magnetic body, especially for the magnetic body with high magnetic field, a better structure and process improvement technology is needed to meet the increasing demand of human beings for pillows. Summary of the invention
[0006] The purpose of the invention is to provide a manufacturing process of an integrated foamed magnetic health-care pillow with high production efficiency and higher pillow quality.
[0007] The above-mentioned purpose of the present invention is achieved through the following technical scheme: a manufacturing process of an integrated foamed magnetic health-care pillow, comprising the steps of: S1, opening the mold and suspending and laying a layer of upper flexible limiting structure in the pillow base foaming molding groove of the mold; S2, arranging a plurality of inverted magnetic particles located on the upper side surface of the upper flexible limiting structure in the pillow base foaming molding groove of the mold; S3, closing the mold and filling the pillow base foaming molding groove with foaming material to foam to form an integrated foamed magnetic health-care pillow; S4, demolding.
[0008] As a preferred embodiment of the present invention, in step 1, the upper flexible limiting structure is a continuous soft gasket, and the vertical projections of all magnetic particles in the up and down directions all fall within the area where the continuous soft gasket is located.
[0009] As a preferred embodiment of the present invention, a plurality of upright positioning piles extending upward and used to support a suspended continuous soft pad and position magnetic particles suspended inside the pillow base are installed at the bottom of the foaming molding groove of the pillow base. The positioning piles are magnetic piles that can be attracted by magnetic materials. The magnetic particles are placed on the positioning piles through a positioning mold, and a magnetic positioning hole that passes through the positioning mold and is used for the magnetic particles to be placed from top to bottom is formed.
[0010] As a preferred embodiment of the present invention, the continuous soft gasket is pre-tensioned on the lower surface of the positioning mold. After the continuous soft gasket is placed on the positioning pile along with the positioning mold, magnetic particles are placed from top to bottom through the magnet positioning hole on the positioning mold and positioned on the positioning pile.
[0011] As a preferred embodiment of the present invention, a plurality of foaming circulation shaping holes which penetrate from top to bottom are formed on the continuous soft gasket, and upper connecting ribs are formed on the periphery of the foaming circulation shaping holes of the continuous soft gasket. In step S1, a part of the upper connecting ribs rests between the top of the positioning pile and the magnetic particles.
[0012] As a preferred embodiment of the present invention, in step S3, the temperature of the mold is controlled between 25-55 degrees Celsius, and the temperature of the foaming material during injection is controlled between 15-30 degrees Celsius.
[0013] As a preferred embodiment of the present invention, before step S2, the back side of the magnetic particles is prefabricated with a support and reinforcement anti-flip gasket. In step S2, after the magnetic particles are inverted and set on the upper side of the continuous soft gasket, the support and reinforcement anti-flip gasket is located on the upper side of the magnetic particles.
[0014] As a preferred embodiment of the present invention, in step S2, a plurality of magnetic strips are arranged in the pillow base foaming molding groove of the mold, which are suspended in the pillow base foaming molding groove and located on the upper surface of the upper flexible limiting structure.
[0015] As a preferred embodiment of the present invention, in step S3, the foaming material is injected into the foaming molding groove of the substrate through a syringe.
[0016] As a preferred embodiment of the present invention, in step S3, the foaming material is injected into the substrate foaming molding groove at a first feeding speed and submerges the upper flexible limiting structure; then the foaming material is injected into the substrate foaming molding groove at a second feeding speed and submerges the magnetic particles; then the foaming material is injected into the substrate foaming molding groove at a third feeding speed until the substrate foaming molding groove is filled, and the first feeding speed is greater than the second feeding speed.
[0017] Beneficial effects of the present invention: 1. The production process can better arrange magnetic particles in the pillow. Through a professional and effective production method, the magnetic particles can be better embedded in the foam pillow, and it is not easy to cause the magnetic particles to flip or shift. 2. The production method of the pillow adopts a special mold, which has better controllability, can produce high-quality pillows, and has a better structural rationality.
[0018] 3. The production process is one-stop, without many other turnover processes and subsequent processes. The magnetic particles can be integrated into the pillow directly through foaming molding, without the need for other steps such as grooving, and the efficiency is relatively high.

DETAILED DESCRIPTION
[0020] The present invention is further described in detail below in conjunction with the accompanying drawings.
[0021] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
[0022] Embodiment 1, as Figure 1-7As shown, an integrated foamed magnetic health pillow comprises an integrated foamed pillow base 1, which is basically formed by a foaming material through a foaming process, and a plurality of magnetic particles 2 are hidden inside the pillow base 1. The magnetic particles in the present application are invisible or basically invisible, are hidden, and are arranged inside the pillow base. Furthermore, an upper flexible limiting structure is also provided inside the pillow base 1, which is supported by the upper side of the magnetic particles 2 to limit the upper side of the magnetic particles 2 and has the ability to deform. A lower flexible limiting structure is also provided inside the pillow base 1, which is supported by the lower side of the magnetic particles 2 to limit the lower side of the magnetic particles 2 and has the ability to deform. The magnetic particles 2 are clamped between the upper flexible limiting structure and the lower flexible limiting structure. The magnetic particles 2 are suspended between the upper and lower flexible limiting structures and are suspended in the upper surface portion of the pillow matrix 1. A sandwich structure is formed between the magnetic particles 2, the upper flexible limiting structure and the lower flexible limiting structure. This sandwich structure is suspended in the portion close to the upper surface of the pillow matrix 1, and must be in the upper half of the pillow matrix. The main purpose is to ensure that the position of the magnetic particles is close to the pillow surface as much as possible, generally controlled within 60% to 95% of the pillow height. For example, for a pillow matrix with a height of 15 cm, the center of the magnetic particles 2 can be selected to be about 12 cm high. Why is the center of the magnetic particles 2 mentioned here? Because the magnetic particles 2 themselves are also about 5 mm thick, so the upper and lower centers of the magnetic particles themselves are used as base points for example. The position of the pillow matrix 1 is A first positioning air temporary storage hole k1 is formed on the portion where each magnetic particle 2 is located and corresponds to the upper and lower parts of the magnetic particle 2, extending from the upper surface of the portion to the upper surface of the magnetic particle 2 and to the upper flexible limiting structure. That is, a first positioning air temporary storage hole k1 is opened on the portion where the pillow base is located between the upper surface of the magnetic particle 2 and the upper surface of the pillow base. The first positioning air temporary storage hole k1 extends from the upper surface of the pillow base to the upper surface of the upper flexible limiting structure. Here, the first positioning air temporary storage hole k1 and the magnetic particle 2 are to be separated by the upper flexible limiting structure, but the bottom end of the first positioning air temporary storage hole k1 is to be exactly above the magnetic particle 2, that is, the first positioning air temporary storage hole k1 is directly above the magnetic particle 2. In the area, if the first positioning air temporary storage hole k1 is upright, then the entire first positioning air temporary storage hole k1 is in the area directly above the magnetic particle 2, that is, the vertical projection of the first positioning air temporary storage hole k1 is completely within the vertical projection of the corresponding magnetic particle 2. Although one magnetic particle can correspond to more than two first positioning air temporary storage holes k1, this embodiment recommends using only one first positioning air temporary storage hole k1, and each magnetic particle 2 corresponds to a first positioning air temporary storage hole k1 directly above it. In this way, the controllability is better and the accuracy is higher during positioning, and the structural loss of the pillow base 1 is also less, and the first positioning air temporary storage hole k1 is preferably located in a central position directly above the magnetic particle 2.This is more suitable for an upright first positioning air temporary storage hole k1, or at least the lower end of a single first positioning air temporary storage hole k1 is located in a central position directly above the magnetic particle 2, that is, the lower end of the first positioning air temporary storage hole k1 is used to position the magnetic particle 2. The magnetic particles are preferably in a round or rectangular shape, so that the axis can be easily and effectively positioned with the axis of the lower end of the first positioning air temporary storage hole k1. Therefore, the first positioning air temporary storage hole k1 is preferably an upright and more regular hole structure. In fact, our core is to use the lower end of the first positioning air temporary storage hole k1 as a positioning point, which is very suitable for positioning the magnetic particles 2. To put it simply, one magnetic particle 2 corresponds to one first positioning air temporary storage hole k1. The first positioning air temporary storage hole k1 is located in the middle above the magnetic particle 2, and the two are separated by the upper flexible limiting structure. In addition, the horizontal dimension of the first positioning air temporary storage hole k1 should be as small as possible. The magnetic particles are placed in a flat state. The horizontal dimension of the magnetic particle 2, that is, the projection dimension in the vertical direction, is generally about 1 square centimeter. The average dimension of the horizontal cross-section of the first positioning air temporary storage hole k1 is controlled within 0.25 square centimeters, and the horizontal cross-section dimension of the upper part that will be exposed on the pillow surface should be small, while the horizontal cross-section dimension of the lower part close to the upper flexible limiting structure should be larger. In this way, the surface part reduces the damage of the structural opening, ensures the aesthetics and structural strength, and is not easy to tear and break. In short, the horizontal cross-sectional size of the upper end part of the first positioning air temporary storage hole k1 should be as small as possible, preferably within 0.1 square centimeters. The specific position of this upper end part can be the horizontal cross-sectional size of a section of the first positioning air temporary storage hole k1 from the top to the bottom that is at least 5 mm long, that is, the average size of the horizontal cross-sectional size of the uppermost section of the first positioning air temporary storage hole k1 that is at least 5 mm long. If it is cylindrical, it is preferably controlled within 0.1 square centimeters. Furthermore, it can be controlled at about 0.05 square centimeters and as large as possible. 0.01 square centimeters, because the first positioning air temporary storage hole k1 also has a function of temporarily storing air, it has a buffering function, because the foaming material It is also breathable and has a large porosity, but the pores themselves are at the micron level, and the amount of air that can be stored is relatively small. The upper and lower dimensions of the first positioning air temporary storage hole k1 are at least centimeters in length, and the average horizontal cross-sectional size is generally more than 1 square millimeter. Therefore, in the unused state, that is, the state where the pillow base is not compressed, the first positioning air temporary storage hole k1 will accommodate more air, and the lower side of the first positioning air temporary storage hole k1 is blocked by magnetic particles. When the user leans on the upper surface of the pillow base through the head or other parts, it is against the upper side of the first positioning air temporary storage hole k1 and blocks the upper side of the first positioning air temporary storage hole k1. In this case, the relatively large amount of air stored there needs to be a process in which it can only be discharged horizontally around through the pores, which can play a better buffering role.More comfortable and reliable. It should be noted that the pillow base 1 is a structure similar to a rectangular body, and the upper surface has a slight curvature. As the main leaning surface, it still needs to be slightly flat. Here, the front and back middle area is slightly concave, and the front and back sides are slightly convex. When not in use, the ups and downs are controlled within 1 cm as much as possible. The middle is also the main area for the head to lean on, and then the position around the pillow will adopt an arc transition structure. This can refer to the shape of existing pillows, so the shape can refer to the various shape design styles of existing pillows, but the number of magnetic particles inside needs to be sufficient, and the area covered as much as possible should account for more than 50% of the horizontal width of the upper part of the pillow base 1, that is, as much as possible. Lay it out in the horizontal direction, of course, the magnetic particles are separated. In addition, try to set it in the area extending from the center of the top of the pillow to the surrounding area, and extend it as much as possible to the left and right, because the pillow is relatively long in the left and right direction, and the user sometimes moves the head or multiple users use it. The arrangement of the magnetic particles in the front and back direction can be set in the front and back middle area as much as possible, because the head and neck are generally leaning in the middle, and the magnetic particles mainly act on the head and neck. ,
[0023] In this special structural design, the flexible limit on the upper and lower sides makes it difficult for the magnetic particles to flip and displace, and compared with the existing technology, the structure of the gel is reduced. When in use, after the upper surface of the pillow base is partially compressed, the upper surface of the magnetic particles can be closer to the human body, and the effect of the magnetic function is more obvious. At the same time, the first positioning air temporary storage hole k1 can not only be used for positioning, but also have a better buffering effect. Moreover, compared with the existing structure of slotting the surface of the pillow to place magnets, the structural integrity is better, the process is simpler, and the magnetic particles can be directly suspended in the pillow base during the foaming process. The problem of position change of the magnetic particles is not easy to occur, the wrapping is also better, and the comfort of use will be better. When the user leans on the pillow part where the magnetic particles are located, there is a buffering adaptation process with the support of the pillow base and the temporary support of the air temporary storage of the first positioning air temporary storage hole k1, which has a certain protective effect on the human body and the magnetic installation structure itself, reducing the damage caused by the instantaneous impact force. Moreover, the aforementioned sandwiched magnetic particle installation structure is also used as a magnetically connected suspension structure, which has better stability and can maintain a good use state in a repetitive extrusion and leaning state. The whole structure is more concise, and it can support immersion cleaning without using gel and glue, and can also maintain the stability of the structure. The specific implementation method of the above scheme is as follows: in the original state, the thickness of the part of the pillow base 1 located above each magnetic particle 2 and corresponding to the upper and lower parts of the magnetic particle 2 does not exceed 5 cm, that is, in the unused state, the pillow of the foam material is not compressed. At this time, it is the thickest time. At this time, the thickness of the part of the pillow base 1 located just above the upper surface of the magnetic particle 2 is preferably not more than 5 cm. Generally, it is recommended to control the thickness to about 2 cm. It is easy to achieve here by selecting the existing foam material, that is, when the pillow base 1 is not used or is in a state of force compression, the distance between the magnetic particles and the upper surface of the pillow needs to be controlled to ensure that the magnetic particles are not too close to the surface when not in use, but can be very close to the human body when in use, and preferably controlled in the used state, the minimum thickness of the part of the pillow base 1 located above each magnetic particle 2 and corresponding to the upper and lower parts of the magnetic particle 2 after leaning and compression does not exceed 10 mm, and further, it is recommended to be about 4 mm. In this way, the effect of the magnetic field on the human body by the surface of the magnetic particles can be greatly exerted, and the comfort is also better, and the human body is more comfortable to lean on. This can be selected independently according to the type and density of the material, and it is only necessary to ensure that the size requirement is met. That is, when not in use, the thickness of the pillow base 1 where the magnetic particles are resting is about 2 cm, and when in use, it is about 4 mm. Of course, this is a more recommended size, and it can also be selected according to the characteristics of the actual user, the environment and materials used, etc.
[0024] In addition, as mentioned above, the size of the first positioning air storage hole k1 is preferably much smaller than the size of the magnetic particles 2. Here, it mainly refers to the horizontal transverse size, that is, the size of the horizontal cross-section of the first positioning air storage hole k1 is smaller than the horizontal size of the magnetic particles 2. It can also be understood that the first positioning air storage hole k1 is thinner.
[0025] Further, at least one section of the first positioning air temporary storage hole k1 is a tapered section with a gradually increasing diameter from top to bottom, so that the size of the formed hole is smaller as it is closer to the top, which provides protection for the pillow itself and the user. Here, the first positioning air temporary storage hole k1 can be a tapered hole with a small top and a large bottom, or a certain section of it can be a tapered section. Here, the aforementioned is the diameter, that is, the tapered section with a circular horizontal cross section, which is actually a truncated cone section. Of course, it can also be a rectangular truncated cone section with a rectangular horizontal cross section. In summary, at least one section of the first positioning air temporary storage hole k1 is a tapered section with a gradually increasing horizontal cross section from top to bottom. The purpose of this is to make the hole part on the surface relatively small, to ensure the integrity of the pillow surface structure, but also to locate the magnetic particles in the production process. Of course, if it is not a whole tapered hole, it can be extended and connected to form a cylindrical section on the upper side of the tapered section of the first positioning air temporary storage hole k1 and also extended and connected to form a cylindrical section on the lower side. The purpose is to have a change in the horizontal cross-sectional size between the upper and lower parts, and it is a process of gradually increasing from top to bottom. The first positioning air temporary storage hole k1 is located in the area directly above the magnetic particles 2 to play the role of positioning and air temporary storage, and is also convenient for cleaning.
[0026] Furthermore, the interior of the pillow base 1 is also provided with a magnetic strip 3 extending left and right. The magnetic strip 3 can be an existing long rectangular structure and is flat. The magnetic strip 3 is against the lower side of the upper flexible limiting structure and suspended in the upper surface of the pillow base 1. The pillow base 1 is located above each magnetic strip 3 and corresponds to the upper and lower parts of the magnetic strip 3. There are more than two second positioning air temporary storage holes k2 extending from the upper surface of the part to the upper surface of the magnetic strip 3 and reaching the upper flexible limiting structure. Here, the magnetic strip 3 is usually a flexible magnetic strip, which is generally about 50 cm long, about 1.5 cm wide, and about 3 mm thick. The overall flexibility is good. It is not recommended to use the lower flexible limiting structure on the lower side. The magnetic particles are small in size, large in magnetism, and high in hardness, so they are easy to flip and displace. The magnetic strip is relatively stable. The compression deformation of the lower side caused by the extrusion process of the pillow base can be well integrated and deformed for the magnetic strip, so it can adapt to the deformation well. The second positioning air temporary storage hole k2 has the same function as the first positioning air temporary storage hole k1, but it is set for the magnetic stripe 3, and the second positioning air temporary storage hole k2 is located in the area directly above the magnetic stripe 3. Another difference is that there are multiple second positioning air temporary storage holes k2 corresponding to each magnetic stripe 3, that is, multiple second positioning air temporary storage holes k2 arranged at intervals on the left and right are set directly above the magnetic stripe 3, and the magnetic stripe 3 is positioned by the second positioning air temporary storage holes k2 arranged at intervals on the left and right. The shape style of the second positioning air temporary storage hole k2 can refer to the first positioning air temporary storage hole k1. For example, the second positioning air temporary storage hole k2 can also be a tapered hole with a diameter that gradually increases from top to bottom, or at least one section of the second positioning air temporary storage hole k2 is a tapered section with a horizontal cross-section that gradually increases from top to bottom, and the multiple second positioning air temporary storage holes k2 corresponding to the upper side of each magnetic stripe are arranged at intervals on the left and right.
[0027] The requirement for the magnetic field is that the upper magnetic field intensity of the magnetic particles 2 is preferably not less than 2000 Gauss and is more than three times the upper magnetic field intensity of the magnetic stripe 3. The upper magnetic field is the magnetic field intensity at the upper surface of the magnetic particles and the magnetic stripe. The magnetic field intensity of the space position closest to the upper surface of the magnetic particles and the magnetic stripe in the space magnetic field above the magnetic particles and the magnetic stripe is the highest. It will gradually decay as the spatial height increases, so the closer to the upper surface of the magnetic object, the higher the magnetic field. Generally, the upper magnetic field intensity of the magnetic particles 2 can be more than 5000 Gauss, and the magnetic field intensity of 6000 Gauss or 8000 Gauss can be set, and the upper magnetic field intensity of the magnetic stripe can be 700 Gauss or 800 Gauss. So here, the magnetic particles need to be magnetic objects with strong magnetic fields, which are very effective for the human body. The magnetic stripe is mainly stretched to support the pillow structure on the front and back sides to ensure a certain strength, and of course it also has a certain magnetic health care effect. Similarly, in the original state, the thickness of the portion of the pillow base 1 located above each magnetic stripe 3 and corresponding to the upper and lower parts of the magnetic stripe 3 does not exceed 5 cm; in the use state, the minimum thickness of the portion of the pillow base 1 located above each magnetic stripe 3 and corresponding to the upper and lower parts of the magnetic stripe 3 after leaning and compression does not exceed 10 mm. The specific size can refer to the preferred setting of the distance between the magnetic particles and the upper surface of the pillow base, and the magnetic stripe 3 and the second positioning air storage hole k2 are also separated by the upper flexible limiting structure.
[0028] As for the arrangement of magnetic particles and magnetic stripes, we adopt the following method, magnetic particles 2 are in the interval area between two magnetic stripes 3 arranged at intervals in front and back, of course, magnetic particles and magnetic stripes themselves are in the upper part of the pillow matrix, which refers to the spatial position of the two. In this way, magnetic particles with larger magnetic field can be placed in the middle, and magnetic stripes with smaller magnetic properties are placed in front and back, forming a regular magnetic distribution interval. The implementation method here is to select two magnetic stripes arranged at intervals in front and back, and then set three rows of magnetic particle queues distributed at intervals in front and back at the interval between the two magnetic stripes, each row of magnetic particle queues is formed by multiple magnetic particles arranged at intervals in the left and right, and the length of each row of magnetic particle queues and the length of magnetic stripes are controlled as much as possible, and the deviation is not too large, and then, the five-row structure formed by these two magnetic stripes and three rows of magnetic particle queues can be kept consistent in the interval distance in front and back, and the deviation is not too large, and the implementation effect of such an arrangement is relatively good, of course, other magnetic material arrangement methods can also be adopted. It is generally appropriate for each magnetic particle queue to have at least 6 magnetic particles, and it is generally appropriate for the total number of magnetic particles to be more than 20, but it is not necessary to have too many, and about 30 is more appropriate. Alternatively, it is also possible to preferably add two magnetic strips on the basis of the aforementioned five rows to form a seven-row structure, and the two newly added magnetic strips are respectively located at the front and back sides of the aforementioned five-row structure, that is, there will be two spaced magnetic strips on the front side of the pillow, and two spaced magnetic strips on the back side of the pillow.
[0029] Next, the specific implementation method of the limiting structure is further explained, wherein the upper flexible limiting structure is selected to be a continuous soft gasket 4 that can cover all the magnetic particles 2, the continuous soft gasket 4 is a whole continuous gasket, that is, each part is connected to other parts to be continuous, and the continuous soft gasket 4 is preferably an overall approximately rectangular structure, and can cover all the magnetic particles 2 on the upper side, and a number of foaming circulation shaping holes 40 that pass through the upper and lower parts are formed on the continuous soft gasket. Since the magnetic particles are in a suspended structure, the foaming circulation shaping holes 40 can be filled with foaming materials during the inverted molding process. Of course, if some foaming circulation shaping holes 40 are bidirectionally clamped by magnetic particles or some positioning structures, it may be difficult to fill them. On the one hand, there are very few such foaming circulation shaping holes 40. Even if there are such holes, the impact on the structure is relatively small. On the other hand, even if there are such holes, as long as some positioning grooves or concave-convex structures are opened on the positioning structure or the surface of the magnetic particles to form gaps, the foaming material can still enter the hole and fill it. In this way, the continuous soft gasket 4 plays the role of a steel mesh in the foaming molding process of the pillow matrix, and the foaming material can be better attached to the upper and lower parts and itself. Moreover, due to the existence of the foaming circulation shaping holes 40, the continuous soft gasket 4 can be formed by the circulation of foaming materials up and down. At the same time, since the foaming circulation shaping holes 40 are also filled with foaming materials, the magnetic particles 2 can be more completely covered on the upper side. The first positioning air temporary storage hole k1 is the foaming material filled in the continuous soft gasket 4 and the foaming circulation shaping holes 40 of the continuous soft gasket 4. Therefore, the magnetic particles can be completely covered and are hidden. Furthermore, the magnetic particles 2 are covered with at least one complete foaming flow shaping hole 40, that is, the horizontal outer dimensions of the magnetic particles 2 are larger than the foaming flow shaping hole 40, so as to ensure that the magnetic particles 2 cannot pass through the foaming flow shaping hole 40. The foaming flow shaping hole 40 can be a regular hole shape such as a square, diamond or circle, and the area is generally smaller than half of the upper surface area of the magnetic particles. For example, the area of the foaming flow shaping hole 40 is one-fifth to one-tenth of the upper surface area of the magnetic particles, which is more recommended. The continuous soft gasket 4 is located at The periphery of the foaming circulation shaping hole 40 is formed with an upper connecting rib 41, which can be understood as the entity part of the outer peripheral encirclement formed by the foaming circulation shaping hole 40, and at least one part of the upper connecting rib 41 can be located in the area surrounded by the bottom of at least one of the first positioning air temporary storage holes k1. It can also be seen here that the first positioning air temporary storage hole k1 will be separated by the upper connecting rib 41 on the lower side, so that the first positioning air temporary storage hole k1 and the magnetic particles are respectively located on the upper and lower sides of the upper connecting rib 41, thereby achieving the aforementioned various beneficial effects. Such a design can make the foaming structure stronger and more stable, and the foaming shaping effect better, just like the steel bars of cement, which better fuse the foaming materials together.The continuous soft gasket 4 here corresponds to all the magnetic particles, that is, one continuous soft gasket 4 covers all the magnetic particles.
[0030] As for the preferred design of the lower flexible limiting structure, it is recommended to adopt a different design concept. Specifically, the lower flexible limiting structure includes a number of discretely arranged support and reinforcement anti-rollover gaskets 5 located on the lower side of the magnetic particles 2 and abutting against them, that is, the lower flexible limiting structure is composed of a plurality of support and reinforcement anti-rollover gaskets 5. In addition, it is more important that the softness of the support and reinforcement anti-rollover gasket 5 is lower than the softness of the continuous soft gasket 4. The continuous soft gasket 4 is on the upper side, has a larger length, and is the first to be compressed and deformed, and the shape of the extrusion deformation is relatively undulating, requiring a follow-up deformation with greater softness. As the lower part already has compression buffering of the pillow base on the upper side, and the support and reinforcement anti-rollover gasket 5 is in the relatively thick area in the middle and lower part of the pillow base, the support and reinforcement anti-rollover gasket 5 can adopt a relatively lower softness. Moreover, a further optimized solution is that each supporting and reinforcing anti-rollover gasket 5 is covered with at least one complete magnetic particle 2. Here, the vertical projection area of each supporting and reinforcing anti-rollover gasket 5 is larger than the vertical projection area of the magnetic particles. For example, the horizontal size of the magnetic particles is understood to be its vertical projection area, which is generally 1 square centimeter. Then the vertical projection area of the supporting and reinforcing anti-rollover gasket 5 is larger than that of the magnetic particles and is preferably more than two times and less than four times, because the effect of being too large is not ideal. For example, the horizontal area size of the supporting and reinforcing anti-rollover gasket 5 can be selected to be 3 square centimeters. Centimeters or 4 square centimeters, further preferably, one magnetic particle is equipped with a support and reinforcement anti-turnover pad 5, the vertical projection shape of the support and reinforcement anti-turnover pad 5 and the vertical projection shape of the magnetic particles can be selected to be the same, for example, the vertical projection of the magnetic particles is circular, then the vertical projection of the support and reinforcement anti-turnover pad 5 can also be selected to be circular, and the magnetic particles are in the central area of the upper surface of the support and reinforcement anti-turnover pad 5 and the axes of the two are kept consistent as much as possible, that is, each magnetic particle is attached to the center of the upper surface of a support and reinforcement anti-turnover pad 5, and each support and reinforcement anti-turnover pad 5 is equipped with only one magnetic particle. Such a design further strengthens the stability of the position of the magnetic particles, is not easy to turn over, and is not easy to damage the matrix itself, and each support and reinforcement anti-turnover pad 5 is discrete and spaced from each other, and the spacing between two adjacent support and reinforcement anti-turnover pads 5 is generally controlled to be about 1 cm, which should not be too small or too large.This structure is similar to the structure of a big tree or a hot air balloon. The support and reinforced anti-rollover gasket 5 is equivalent to the root system of the tree or the pulling rope around the hot air balloon. Since the support and reinforced anti-rollover gasket 5 is larger than the horizontal size of the magnetic particles and completely covers the magnetic particles on the lower side, and the hardness of the support and reinforced anti-rollover gasket 5 is relatively high, it can effectively prevent the magnetic particles from being affected by other magnetic particles as a whole and flipping when the lower side is squeezed and deformed. Moreover, this discrete root structure allows users in different areas to use it and still adapt to the deformation, squeezing and diffusion of the upper side. Because they are discrete, they can adapt very well even if the hardness is high. Here, it can also be said that the hardness of the support and reinforced anti-rollover gasket 5 is greater than that of the continuous soft gasket 4. The Shore D hardness of the continuous soft gasket 4 can be selected between 30-60, and the Shore D hardness of the support and reinforced anti-rollover gasket 5 can be selected between 70-90. However, the entire area of the continuous soft pad 4 is preferably about a hundred times the area of the supporting and reinforcing anti-rollover pad 5. For example, if the area of a supporting and reinforcing anti-rollover pad 5 is 4 square centimeters, then the continuous soft pad 4 can be 1000-2000 square centimeters. Such a structural design is more suitable for this pillow structure.
[0031] Preferably, a plurality of auxiliary connection meshes 50 are formed on the support and reinforcement anti-rollover gasket 5, and a lower connection rib 51 is formed on the periphery of the auxiliary connection mesh 50 of the support and reinforcement anti-rollover gasket 5. This makes the molding structure of the lower foam material more stable. Here, the support and reinforcement anti-rollover gasket 5 is opened with reference to the continuous soft gasket 4, and the lower connection rib 51 is formed, which is also for the compatibility of the foam molding structure, and will be more solid. The foam material is attached and molded along the ribs and meshes and has a skeletal structure with meridians to strengthen the strength. Moreover, similarly, the hole size of the auxiliary connection mesh 50 is smaller than the lower surface area of the magnetic particles. Of course, the upper and lower surfaces of the magnetic particles are generally basically the same, and the design can be the same as the aforementioned foaming circulation shaping hole 40. If there is optimization, the holes of the auxiliary connection mesh 50 can be diamond holes, and the foaming circulation shaping holes 40 can be hexagonal holes. However, the difference in the size of the holes between the two should not be too large, and try to keep the same size. Because the overall deformation of the continuous soft gasket 4 is large, the hexagonal structure has better adaptability, and the supporting and reinforcing anti-rollover gasket 5 is a locally smaller structure, so this structure with fewer sides is relatively stable to ensure strength. Furthermore, the four sharp corners of the diamond holes of the auxiliary connection mesh 50 are oriented in the left and right directions and the front and back directions as much as possible, consistent with the direction of the pillow, so that the structural compatibility is relatively good.
[0032] It is further preferred that the periphery of the continuous soft pad 4 is formed with a plurality of upper periphery transition connecting ribs 42 integrally connected to the upper connecting ribs 41, and the periphery of the supporting and reinforcing anti-rollover pad 5 is formed with a plurality of lower periphery transition connecting ribs 52 integrally connected to the lower connecting ribs 51. The upper periphery transition connecting ribs 42 and the lower periphery transition connecting ribs 52 are similar to capillaries or branches on a main road. Such branches are for better extending to the surrounding foaming material, so that the stability of the overall foaming material structure after molding will be better and it will not be easily deformed and damaged, that is, the role of supporting and reinforcing the root system of the anti-rollover pad 5 will be better played. Of course, the upper side of the overall continuous soft pad 4 also has such transition connecting ribs 52 on the four peripheries of the front, back, left and right, that is, the foam molding around the pillow base is more solid.
[0033] In addition, in the above structure, the recommended material selection is that the pillow base 1 is made of foamed sponge or foamed latex, that is, it is formed by foaming sponge raw materials or latex raw materials. It is also mentioned above that if the softness of the support and reinforcement anti-turnover gasket 5 is less than the softness of the continuous soft gasket 4, the support and reinforcement anti-turnover gasket 5 can be made of nylon plastic material, and the continuous soft gasket 4 can be made of polyester fiber material. Furthermore, the thickness of the support and reinforcement anti-turnover gasket 5 is greater than the thickness of the continuous soft gasket 4. For example, the thickness of the support and reinforcement anti-turnover gasket 5 is 1.5-2 mm. The thickness of the continuous soft gasket 4 can be 0.5-1 mm.
[0034] Furthermore, the outer ends of the upper peripheral transition connecting ribs 42 and the lower peripheral transition connecting ribs 52 are free ends. As mentioned above, the lower peripheral transition connecting ribs 52 are to extend to the foam material and be connected with the foam material. It can be seen that one end of the lower peripheral transition connecting ribs 52 is integrally connected with the lower connecting rib veins 51 that support and strengthen the main body of the anti-turnover gasket 5, while the other end does not need to be connected with the lower connecting rib veins 51, but is preferably a free end that is only in contact with the foam material, that is, it can be used as a capillary-like tight connection around the gasket. The upper peripheral transition connecting ribs 42 are also designed with the same idea.
[0035] Through the above design, the magnetic particles can be suspended in the complete pillow matrix, and the molding can be completed in one step. The magnetic particles are not only better protected, but also can be used closer to the human body, with better cushioning during use, and the magnetic field effect is better. The pillow structure itself is more stable and not easy to be damaged or deformed. The flipping and translocation problems of the magnetic particles are effectively solved, which greatly improves the original problem of the pillow with a structure such as gel on the surface, which is easy to break and produce odor. Moreover, the same magnetic field can be better exerted in the structure of this application. The entire pillow structure design concept has been greatly improved, and a new production process can be formed. The comfort, stability, and magnetic function of this pillow can be greatly enhanced, and the structure is simple but not simple. The cost control has also been well strengthened, including production and later use, after-sales costs, etc.
[0036] Embodiment 2, as Figure 8-16 As shown, a mold for producing a foam pillow is shown. This embodiment is a mold specially designed for the pillow in Example 1, and can very effectively produce the one-piece foam magnetic health pillow in Example 1.
[0037] Specifically, it includes an upper mold m1 and a lower mold m2 which can be assembled and opened up and down, and the lower mold m2 is formed with an inverted pillow base foaming molding groove m20 for foaming and molding to produce the pillow base. The inverted shape means that the pillow base is foamed upside down, and the pillow base is a pillow main body supporting structure formed by foaming the foaming material. Furthermore, it is also a special design point of this embodiment, that is, the lower mold m2 is located at the bottom of the pillow base foaming molding groove m20 and is equipped with an internal suspended positioning structure that extends upward and is used to position the suspended embedded built-in structure inside the pillow base. The suspended embedded built-in structure is supported and suspended in the air by the internal suspended positioning structure. Then, during the foaming process, the suspended embedded built-in structure is directly embedded in the pillow base, so that after foaming, the suspended embedded built-in structure is suspended and embedded in the foamed pillow base, and the left and right front and back positions and the up and down lengths of the internal suspended positioning structure can be controlled to control the position of the suspended embedded built-in structure in the pillow after final molding.
[0038] In one embodiment, the internal suspension positioning structure includes a plurality of upright positioning piles m3, the top of which is used to place and position the suspension embedded built-in structure. The upper portion of the positioning pile m3 in the foaming molding groove m20 of the pillow base is used to form the first positioning air temporary storage hole k1 or the second positioning air temporary storage hole k2 during the foaming molding, so these two holes can be positioned and suspended and embedded in the built-in structure in the production process, and have good use value after the later molding.
[0039] Preferably, the positioning pile m3 is a magnetic pile that can be attracted by magnetic objects, and can be positioned and connected to the suspended embedded built-in structure by magnetic attraction. Correspondingly, the suspended embedded built-in structure includes magnetic particles and / or magnetic strips, so that the magnetic particles and magnetic strips can be temporarily placed and connected to the positioning pile m3 by magnetic attraction. Moreover, due to the design of the structure, it will not affect the demoulding much, and the magnetic attraction force can still relatively easily separate the positioning pile m3 from the magnetic particles and magnetic strips. In addition, the positioning pile m3 can be electromagnetic instead of permanent magnetic. For example, the external structure of the positioning pile m3 is non-ferromagnetic, such as aluminum parts, and an electromagnetic coil is set in the positioning pile m3. By charging and discharging to generate magnetism, it can attract, repel, and separate from the magnetic object or ferromagnetic suspended embedded built-in structure.
[0040] The first positioning air temporary storage hole k1 corresponds to the positioning pile m3 for positioning the magnetic particles, and the second positioning air temporary storage hole k2 corresponds to the positioning pile m3 for positioning the magnetic strip. According to the size and arrangement described in Example 1, each first positioning air temporary storage hole k1 and each second positioning air temporary storage hole k2 represent the position of each positioning pile m3. Therefore, it is preferred that one positioning pile m3 positions one magnetic particle, and multiple positioning piles m3 position one magnetic strip. Accordingly, three rows of positioning pile m3 queues are arranged in the front, middle and rear areas in the middle area of the pillow base foaming molding groove m20. Each row of positioning pile m3 queues has a number of positioning piles m3 arranged at intervals on the left and right. The number and positions of the positioning piles m3 in the three rows of positioning pile m3 queues correspond one by one to the number and positions of the magnetic particles, and the alignment of the magnetic particles is generally arranged with the center and the center of the top of the corresponding positioning pile m3 relative to each other. Then, a row of positioning pile m3 queues are respectively set at the front and rear sides of the three rows of positioning piles m3 in the middle area. The front and rear rows of positioning pile m3 queues are used to position a magnetic stripe at the front and a magnetic stripe at the rear, respectively. Each of the two positioning pile m3 queues preferably has more than three positioning piles m3 spaced apart from each other. Then, the positioning piles m3 of each of the two queues support and position one of the magnetic stripes at the bottom, and preferably there are at least three positioning piles m3, which are located at the left end, right end and the middle of a magnetic stripe. Here, in the pillow forming process, the magnetic stripe also needs to be placed upside down on the positioning pile m3. If it is a structure with seven rows of magnetic bodies as mentioned above, two more positioning pile m3 queues need to be added, one at the front and one at the back, which are used by the other two magnetic stripes.
[0041] Furthermore, the positioning pile m3 is detachably connected to the bottom of the foaming molding groove m20 of the pillow base body of the lower mold m2, which is convenient for replacement and maintenance. The detachable method can adopt the following scheme: the outer periphery of the bottom part of the positioning pile m3 is formed with an external thread, and the bottom part of the positioning pile m3 is provided on the bottom part of the foaming molding groove m20 of the pillow base body of the lower mold m2 for screwing and disassembling. This design allows the positioning pile m3 to be threadedly connected on the bottom threaded hole, which is convenient for disassembly and assembly. Of course, it can also be adsorbed on the bottom part of the foaming molding groove m20 of the pillow base body by magnetic suction, but the suction force here needs to be greater, and the positioning pile m3 cannot be pulled out when demolding. Of course, the positioning pile m3 can also be fixed on the bottom part of the foaming molding groove m20 of the pillow base body by existing processes such as welding, which can also be used, but the flexibility is a little worse, so a detachable fixed connection method is still more recommended.
[0042] Preferably, the positioning pile m3 is a pile structure with retractable lengths up and down. The advantage of this structure is that as the foaming raw material is injected, the positioning pile m3 will sink with the suspended embedded built-in structure, and can compress the foaming raw material that first enters the pillow base foaming molding groove m20, because the foaming raw material that enters first has begun to foam and mold, and the foaming agent has begun to react to produce gas, that is, the raw material begins to expand and foam to form loosely, and then due to the gravity of the floating embedded built-in structure and the upper part of the positioning pile m3 and the pressure of the liquid foaming raw material, the raw material on the lower side sinks and squeezes, and part of the gas will go upward, so that the density of the raw material on the lower side of the pillow base foaming molding groove m20 after foaming can be higher, and the strength of the structure of the surface of the finally molded pillow can be better, so that the magnetic material can be better protected.
[0043] The above-mentioned retractable pile structure of the positioning pile m3 can further adopt the following implementation scheme, the positioning pile m3 includes a support section m31, a telescopic section m32 and a mounting section m33 connected in sequence from top to bottom, the upper part of the support section m31 is used to position the floating embedded structure, if the structure is magnetic particles, magnets, then the support section m31 itself can be magnetic attraction type, that is, the support section m31 is ferromagnetic or non-ferromagnetic on the outside and equipped with an existing electromagnetic device inside, so that it can be attracted and positioned with the magnetic object, the telescopic section m32 is fixed to the lower side of the support section m31 in an existing manner, and the telescopic section m32 is fixed to the lower side of the support section m31 in an existing manner. Segment m32 can be an elastic telescopic structure, for example, an upright spring or damping gas rod is used. If it is a spring, the upper and lower ends of the spring can be fixedly connected to the lower part of the support segment m31 and the upper part of the installation segment m33 by existing fixing methods such as welding. If it is a damping gas rod, the damping gas rod is placed upright, the piston rod is on the upper cylinder body and the lower cylinder body is fixed to the upper part of the installation segment m33. The fixing method here can be the existing one. Of course, it is also feasible to connect the damping gas rod upside down with the support segment m31 and the installation segment m33. The installation segment m33 plays the role of a base and is used to be installed and fixedly connected with the lower mold m2 or can also be a movable connection method. This design can enable the positioning pile m3 to achieve a telescopic function. Among them, the horizontal and transverse area size of the magnetic particles and the magnetic strips can be larger than the horizontal cross-sectional size of the support segment m31, which can achieve the effect of pressing the raw materials and make the density of the upper part of the pillow after forming greater.
[0044] Furthermore, at least a section of the portion of the positioning pile m3 above the bottom surface of the pillow base foaming molding groove m20 is in the shape of an inverted cone. Here, the first positioning air temporary storage hole k1 and the second positioning air temporary storage hole k2 are mentioned in Example 1, so one of the functions of the positioning pile m3 is to form the first positioning air temporary storage hole k1 and the second positioning air temporary storage hole k2 during the foaming process, and the positioning pile m3 is formed by the portion located in the pillow base foaming molding groove m20. However, since the molding process is inverted here, it is appropriate to design the upper portion of the positioning pile m3 to be in the shape of an inverted cone, that is, a style that is larger on the top and smaller on the bottom, which refers to the size of the horizontal cross-section, so that a downward pressure effect will also be formed. Here, this section can be on the support section m31, that is, at least one section on the support section m31 is in an inverted cone shape. It can be a whole cone shape or a part of it, and the other part is cylindrical. For example, the preferred support section m31 is fixedly connected by an upper conical support section m311 and a lower cylindrical support section m312, which is beneficial for forming the first and second positioning air storage holes, and can also be used to press down the foaming raw materials.
[0045] For further optimization, a pressure sensor can be set in the positioning pile m3. For example, a pressure sensor can be set in the telescopic section m32. Since the pressure on the positioning pile m3 after being arranged, placed, suspended and embedded in the built-in structure and during the foaming raw material entering the molding process is detected, the position and flow of the raw material injection are controlled according to the detected pressure. A temperature sensor can be configured in the support section m31 to control the injection of the raw material and the temperature control of the molding process by the temperature control mechanism by detecting the molding temperature of the foaming raw material. In addition, a displacement sensor can also be set in the positioning pile m3, which can be used to detect the degree of expansion and contraction of the positioning pile m3, or to detect the height position of the magnetic particles or magnetic strips, because there will be differences in the expansion and contraction process. Generally, production needs need to be kept consistent as much as possible. Of course, sometimes different heights will be controlled according to needs, but this difference is controllable. Here, if the telescopic section m32 is a spring, this is a passive telescopic structure, which is passively and naturally expanded and contracted completely under the pressure from above, and it will lack precise control. In this case, the mounting section m33 can be designed to be able to move up and down. For example, the bottom of the mounting section m33 is connected to an existing lifting mechanism s, such as an automatically controlled screw structure or cylinder structure, or a linear motor, as long as the mounting section m33 can be actively moved up and down. If the telescopic section m32 is a damping gas rod, the damping gas rod can be electrically controlled, that is, it can be automatically controlled, and passive and active telescopic can be switched. There are many existing ones, which are generally controlled by electromagnetic valves. For example, it is passively compressed at the beginning of the feeding stage. According to the pressure detection, the pressure is uniformly used as a reference to control the injection position and flow of the raw material. Then, after the raw material is injected, it is adjusted to active telescopic to control the height position of each magnetic particle or magnetic strip to a predetermined position; of course, it is also possible to uniformly descend according to the position detected by the displacement sensor, and then control the injection position and flow of the raw material according to the pressure received by the positioning pile m3 at different positions. However, in this case, it is best to set a pressure sensor in the support section m31. This is mainly used to detect the liquid pressure of the raw material and the gravity of the suspension structure. Because the damping gas rod is in active telescopic mode, it can only measure the internal damping force. For the consistency of position, some areas will cause certain differences due to the flow of raw materials, and some areas require more active downward pressure. Such multiple position pressure detection can provide a more comprehensive understanding of the internal pressure situation.
[0046] Of course, in order to better achieve installation, an assembly slot m200 extending up and down is provided on the lower mold m2 for the positioning pile m3 to be inserted and assembled. The assembly slot m200 is provided in the part below the bottom of the pillow base foaming molding slot m20 of the lower mold m2, and can be a through hole that penetrates up and down, so that it can be conveniently inserted for installation or movement, etc. If the above structure is adopted, it is generally recommended that the installation section m33 and the telescopic section m32 are cylindrical, and the size of the horizontal cross-section is larger than that of the support section m31, so the lower part of the assembly slot m200 is used to install and connect the installation section m33, and the size of the lower part of the assembly slot m200 is correspondingly larger, and the installation section m3 If it is fixed and does not need to be lifted, the outer periphery of the installation section m33 can be provided with threads to be directly installed and connected in the lower part of the assembly slot m200. The lower part of the assembly slot m200 is formed with corresponding threads, so that it can be connected by threads. Of course, it can also be installed and connected using the existing pin structure, or other existing module installation assembly structures can be connected. As long as the installation section m33 is installed in the lower part of the assembly slot m200, if the bottom of the installation section m33 is connected to the lifting mechanism s, the lifting mechanism s is installed and connected with the lower part of the assembly slot m200, and the installation and connection method can adopt the existing fixed method. The telescopic section m32 can be smoothly extended and retracted in the middle part of the assembly slot m200, so the size of the assembly slot m200 part here can also be slightly larger.However, the portion of the assembly slot m200 near the top through which the support section m31 passes has higher requirements, because on the one hand the support section m31 can be raised and lowered, and on the other hand the raw material should not leak too much into the assembly slot m200 as much as possible. Therefore, the size of the portion of the assembly slot m200 near the top and the portion of the support section m31 that can move up and down should match, and try to ensure consistency. Exceptionally, the inner wall of the portion of the assembly slot m200 near the top can be grooved to embed an O-ring to ensure that the support section m31 can move up and down while preventing the raw material from leaking. Here, if the support section m31 is a whole cylinder, the assembly is relatively simple as long as the size matches. If the support section m31 is composed of an upper conical support section m311 and a lower conical support section m312 as mentioned above, the assembly is relatively simple. A cylindrical support section m312 is fixedly connected, and the cylindrical support section m312 serves as a movable section that can be raised and lowered with the telescopic section m32. The dimensions of the cylindrical support section m312 and the upper part of the assembly slot m200 are as consistent as possible, and the cylindrical support section m312 is passed through the upper part of the assembly slot m200 from top to bottom, and ensure that a part of the cylindrical support section m312 is above the bottom of the pillow base foaming molding slot m20. The lower end of the cylindrical support section m312 is fixedly connected to the upper end of the telescopic section m32. For example, the lower end of the cylindrical support section m312 is fixedly connected to the upper end of the piston rod of the damping gas rod. The fixing method can adopt existing detachable fixing methods such as threaded connection, pin connection, key connection, etc., which is convenient for disassembly and assembly. Furthermore, the lower end of the conical support segment m311 and the upper end of the cylindrical support segment m312 are preferably in a detachable fixed connection relationship for easy operation and assembly. A more preferred method is that a threaded hole extending up and down is opened in the top portion of the cylindrical support segment m312, and a threaded column is integrally connected to the bottom of the conical support segment m311, and the threaded column is threadedly connected to the threaded hole. Of course, other installation methods can also be used, but this method can ensure better structural continuity, and it looks integrated without any protruding or recessed structure. In this structure, a straight groove or a cross groove can be formed on the top of the conical support segment m311 for easy operation, and this does not affect the placement and positioning of the magnetic object, and the center of the cross groove can also be used as a positioning point. Of course, space can be left inside the conical support section m311, the cylindrical support section m312, the telescopic section m32, and the installation section m33 instead of being solid, because sensors, wires and other components will be placed therein. In addition, wire holes can be opened at the bottom of the conical support section m311, the top of the cylindrical support section m312, and the ends or sides of the telescopic section m32 and the installation section m33 to lead out the power wires. Of course, the wires can also be partially routed in the assembly slot m200, or wire holes can be opened in the lower part of the lower mold for routing, as long as the structure in the pillow base foaming molding slot m20 is not affected.
[0047] The aforementioned positioning piles m3 are generally separately arranged, and one positioning pile m3 is composed of a supporting section m31, a telescopic section m32 and a mounting section m33. Next, another embodiment of the positioning pile m3 is provided, and the lower parts of each assembly slot m200 can also be connected, that is, a connecting space t1 that can connect the lower parts of several assembly slots m200 is opened on the lower mold, so that the use of telescopic sections m32 and mounting sections m33 can be reduced, that is, the number of supporting sections m31 is relatively large, and is reasonably selected according to the number of magnetic objects, but the number of telescopic sections m32 and mounting sections m33 can be reduced, and multiple supporting sections m31 can share one telescopic section m32 and mounting section m33. The specific implementation is that the bottoms of multiple supporting sections m31 are fixedly connected to the upper side of a connecting rod t2 that passes through the connecting space horizontally through the existing installation method, and then the lower side of the connecting rod t2 is used to connect and fix to a telescopic section m32 and mounting section m33. The connection method can adopt the existing fixing method, or refer to the aforementioned installation method. This implementation scheme is very suitable when the control accuracy requirements are not very high. It can reduce a lot of structures and controls, reduce the difficulty of production, and is suitable for the needs of mid- to high-end customers.
[0048] Preferably, this mold can be equipped with a positioning mold m4, and the positioning mold m4 is transferred and positioned by mechanical arm clamping and conveying or other existing positioning and clamping equipment. Of course, it can also be manually operated. The positioning mold m4 forms a magnetic positioning hole m40 for magnetic particles or magnetic strips to be placed in and pass through up and down. The positioning mold m4 can adopt a rectangular template, but the overall size of this template is smaller than the overall size of the pillow base foaming molding groove m20, and it can be placed in the pillow base foaming molding groove m20. The lower surface of the positioning mold m4 is used to stick and tension the continuous soft pad 4. When making the pillow, the continuous soft pad 4 is pre-arranged on the lower surface of the positioning mold m4, and the peripheral part of the positioning mold m4 can be installed and connected to some existing clamping mechanisms or vacuum suction The continuous soft gasket 4 can be tightened and released by the attached equipment, so the continuous soft gasket 4 is locked on the lower surface of the positioning mold m4 in advance by the aforementioned clamping mechanism or vacuum adsorption equipment, and then the magnetic particles and magnetic strips are placed in the corresponding magnet positioning holes m40 from top to bottom, and then the positioning mold m4 is accurately moved to the upper side of the positioning pile m3 by the existing infrared or laser positioning structures on the mold and the positioning mold m4, and the continuous soft gasket 4 is attached to the top of the positioning pile m3, and the magnetic particles and magnetic strips are pressed on the upper side of the continuous soft gasket 4, and can be attracted by the magnetic suction, and then the clamping mechanism or vacuum adsorption equipment is released, and the positioning mold m4 is moved up, and the continuous soft gasket 4 and the magnetic particles and magnetic strips can be left on the upper side of the positioning pile m3 and placed on the upper side of the positioning pile m3. Of course, it is also possible not to use the positioning mold, for example, direct placement by manual labor, or other existing direct positioning automatic equipment to place the magnetic particles, magnetic strips and the continuous soft gasket 4 are all feasible. For example, if the magnetic particles are to be pre-connected with the supporting and reinforcing anti-turnover gasket 5, the size of the magnet positioning hole m40 must match the supporting and reinforcing anti-turnover gasket 5, that is, the magnet positioning hole m40 for positioning the magnetic particles must be slightly larger than the lateral size of the magnetic particles. The magnetic strip without the supporting and reinforcing anti-turnover gasket 5 does not require such a design, as long as the size is just right for the magnet to be placed in.
[0049] Preferably, the upper mold m1 and the lower mold m2 are hingedly connected at the rear side, that is, they are hingedly connected by a hinge or other structure, and the front side of the upper mold m1 and the lower mold m2 is provided with a switch mechanism that can be opened and tightened. The switch mechanism can adopt the existing structure. For example, a clamp is respectively fixed on the front side of the upper mold m1 and the lower mold m2, and then the switch is performed by a structure of bolts penetrating from top to bottom and nuts. Of course, a power structure such as a cylinder can also be used to push the upper mold m1 to open and close, and the main function is to realize the switching.
[0050] Preferably, the lower surface of the lower mold m2 is a flat pressed surface that can close the pillow base foam molding groove m20 on the upper side. This plane is to ensure that the bottom surface of the pillow is flat, while the bottom surface of the pillow base foam molding groove m20 does not need to be a plane because it is the real surface of the pillow and can have a slightly curved surface.
[0051] More importantly, a temperature control mechanism is provided on the upper side of the upper mold m1. The foaming process requires good and stable temperature control to ensure higher stability of the product after foaming. The temperature control mechanism is preferably a water temperature control mechanism. The temperature control structure includes a water pipe m10 integrally connected to the upper surface of the upper mold m1. The water pipe m10 and the upper mold m1 are made of the same material, both of which are made of metal, such as steel or aluminum alloy. The lower mold is also made of the same material. The water pipe m10 includes a front pipe section m11, a rear pipe section m12, a left pipe section m13 and a right pipe section m14. The left end of the front pipe section m11 can be connected to the front end of the left pipe section m13, the left end of the rear pipe section m12 can be connected to the rear end of the left pipe section m13, the right end of the rear pipe section m12 can be connected to the rear end of the right pipe section m14, and the front end of the right pipe section m14 is close to the right end of the front pipe section m11 but slightly separated, for example, about 5 cm apart. In this way, one of the right end of the front pipe section m11 and the front end of the right pipe section m14 can be used as the water inlet end and the other end as the water outlet end to connect to an external water pipe. Of course, other connection methods can also be used, but the more important design is that, among the four pipe sections, the adjacent two ends of two adjacent pipe sections are preferably used as free ends as the water inlet and outlet ends. The left pipe section m13 and the right pipe section m14 can be straight pipe sections and extend forward and backward, while the front pipe section m11 and the rear pipe section m12 are both W-shaped and mirror-symmetrical, and the sharp corners of the W-shaped are facing the front and back directions. In this way, the overall water flow channel is similar to a rectangular frame, and the front pipe section m11 and the rear pipe section m12 have a front and back winding section, which can make the overall water temperature control area relatively large and better control the uniformity of the internal temperature.
[0052] The design of the entire mold is very suitable for the production of the foam pillow of Example 1. Not only is the arrangement of the magnet more scientific and reasonable, the suspension structure is more beneficial to the human body and the structure itself, and the cost is greatly controlled. Moreover, this mold has better controllability over foaming, better and more effective control over various foaming conditions, and can control the physical properties of the foaming material itself. The controllability of production is also higher, and it can be suitable for the production of pillows of various qualities.
[0053] Example 3, referring to the drawings in Examples 1 and 2, a process for producing an integrated foamed magnetic health pillow is provided. This process is very suitable for producing the pillow in Example 1. The mold in the process can also adopt the mold in Example 2, and the specific implementation methods involved in Examples 1 and 2 can also be applied to this embodiment.
[0054] The specific process of this embodiment is as follows: including the steps: S1, the mold is opened and a layer of upper flexible limiting structure is suspended and laid in the pillow base foaming molding groove m20 of the mold; S2, a number of inverted magnetic particles are arranged on the upper surface of the upper flexible limiting structure in the pillow base foaming molding groove m20 of the mold; S3, the mold is closed and the foaming material is filled into the pillow base foaming molding groove m20 to foam to form an integrated foaming magnetic health pillow; S4, demoulding. The upper flexible limiting structure is separated from the pillow base foaming molding groove m20 by a distance, so that the upper flexible limiting structure is close to the surface of the molded pillow. This process is consistent with the design concept of the mold. What is molded is an inverted pillow. It is to facilitate the smooth implementation of the molding process, including the design of the suspension structure. Of course, the upper flexible limiting structure needs to be supported by a corresponding suspension structure, and there will be corresponding specific implementation methods later. Inverted magnetic particles refer to the front side of the magnetic particles facing up while the back side faces up. Of course, the magnetic poles of the front and back sides of the magnetic particles are different, but the magnetic field strength is the same. However, the periphery of the front side of the magnetic particles will be rounded or chamfered to remove sharp edges, because the magnetic particles are generally closer to the user when they are used. One is to reduce the discomfort of leaning on the corners, and the other is to reduce the damage caused by the extrusion deformation process on the upper side of the pillow body and the magnetic particles. These sharp edges will be removed from the periphery of the front side. In this process, the molding is inverted, so the magnetic particles also need to be placed inverted, that is, the front side is facing down and attached to the upper flexible limit structure. After all the magnetic particles are inverted and arranged on the upper side of the upper flexible limit structure, the foaming material is put in for foaming. The foaming material can be made of existing sponge foaming materials or latex foaming materials, etc., and can be selected according to different needs. After the foaming molding is completed, the mold is demolded, which can be done manually or by clamping equipment.
[0055] Preferably, in step 1, the upper flexible limiting structure is a continuous soft gasket 4, and the vertical projections of all magnetic particles in the up and down directions all fall within the area where the continuous soft gasket 4 is located. It can be seen here that the projection of the magnetic particles in the vertical direction falls within the vertical projection of the continuous soft gasket 4, that is, after forming, the continuous soft gasket 4 can completely cover and block all magnetic particles on the upper side, avoiding the aforementioned magnetic translocation and other undesirable problems caused by the magnetic particles not being covered by the continuous soft gasket 4. It will also be better for the integrity of the pillow structure and reduce the instability of the fragmented structure.
[0056] Preferably, a plurality of upright positioning piles m3 are installed at the bottom of the foaming molding groove m20 of the pillow base, which extend upward and are used to support the suspended continuous soft pad 4 and position the magnetic particles suspended inside the pillow base. The positioning piles m3 are magnetic suction piles that can be attracted by magnetic objects. The magnetic particles are placed on the positioning piles m3 through positioning molds m4. The positioning molds m4 form magnetic positioning holes m40 that penetrate from top to bottom for the magnetic particles to be placed from bottom to bottom. Here, the positioning mold m4 is also mentioned in the aforementioned embodiment, which can be used in this process. The magnetic particles are arranged on the positioning piles m3 through the positioning molds m4. The positioning molds m4 are movable and can be moved manually or mechanically. The positioning molds m4 The 4 sides can be fixedly connected with handles or support platforms and other structures that are easy to carry, so that manual or mechanical equipment can be used for turnover. Of course, if the magnet positioning hole m40 is circular for placing magnetic particles, the magnet positioning hole m40 can be aligned with the top center of the positioning pile m3. Each magnet positioning hole m40 is aligned with a corresponding positioning pile m3 up and down. Therefore, the layout of the magnet positioning holes m40 for placing magnetic particles is consistent with the layout of all the positioning piles m3 for positioning magnetic particles. To be precise, the number and layout of the hole center and the top center of the positioning pile m3 are consistent. In fact, these two layouts are positioned during positioning, which can be achieved through existing infrared or laser equipment. As mentioned above, the size of the positioning mold m4 should be small and can be placed in the pillow base foam molding groove m20, but the horizontal size of the positioning mold m4 can be larger than the size of the pillow base foam molding groove m20, especially the left-right length of the positioning mold m4 can be larger than the left-right length of the pillow base foam molding groove m20. In this way, the positioning mold m4 can be placed on the lower mold m2 of the mold, but in this structure, the positioning area of the positioning mold m4 is smaller than the horizontal size of the pillow base foam molding groove m20, so that the lower side of the positioning mold m4 can form a downwardly protruding extension block m44, and the extension block m44 also has holes. These holes are extension holes that extend downward and connect to the magnet positioning holes m40 on the positioning mold m4, and the horizontal size of the extension hole is as consistent as possible with the horizontal size of the corresponding magnet positioning holes m40 connected above and below.
[0057] Preferably, the continuous soft gasket 4 is pre-tensioned on the lower surface of the positioning mold m4. After the continuous soft gasket 4 is placed on the positioning pile m3 along with the positioning mold m4, that is, in the implementation method in step 1, the upper flexible limiting structure adopts the continuous soft gasket 4 and is pressed against all the positioning piles m3 along with the positioning mold m4, and then magnetic particles are placed from top to bottom through the magnet positioning hole m40 on the positioning mold m4 and positioned on the positioning pile m3. Here, the magnetic particles are fixed on each positioning pile m3 through the continuous soft gasket 4 and magnetically attracted. The positioning mold m4 here is preferably non-ferromagnetic, for example, a non-magnetic steel or aluminum module.
[0058] Furthermore, a plurality of foaming circulation shaping holes 40 extending vertically are formed on the continuous soft gasket 4, and an upper connecting rib 41 is formed on the periphery of the foaming circulation shaping holes 40 of the continuous soft gasket 4. In step S1, a portion of the upper connecting rib 41 abuts against the top of the positioning pile m3 and the magnetic particles, that is, under the premise of the specific style of the continuous soft gasket 4, the magnetic particles are separated and positioned from the top of the positioning pile m3, but because there is sufficient magnetic attraction, they can still be well attracted and positioned. In this case, if a complete foaming circulation shaping hole 40 is sandwiched between the positioning pile m3 and the magnetic particles, the molding process will affect the foaming material from entering the foaming circulation shaping hole 40. In order to reduce this situation, we can adopt the following measures. For example, the upper part of the positioning pile m3 is the support section m31. Try not to press against the complete foaming circulation shaping hole 40. It can press against the connection between the upper connecting ribs 41 at the junction of multiple foaming circulation shaping holes 40, so that each foaming circulation shaping hole 40 can have room to leave a gap, so that it will not affect the foaming material from entering the foaming circulation shaping hole 40. However, if the top surface size of the support section m31 is large, it will inevitably cover the entire foaming circulation shaping hole 40. At this time, a linear groove can be formed on the front of the magnetic particles, so that the upper connecting ribs 41 where the foaming circulation shaping hole 40 sandwiched by the top surface of the support section m31 and the magnetic particles is located will not block the foaming material from entering in and out. A foaming circulation shaping hole 40 is formed, so that filler can still be placed in the foaming circulation shaping hole 40, or a groove is opened on the top surface of the support section m31. For example, a straight groove or a cross groove such as a positioning groove d can be formed on the top of the support section m31. In this way, there is space for the foaming material to flow into the completely supported foaming circulation shaping hole 40, that is, a part of the upper connecting ribs 41 where the complete foaming circulation shaping hole 40 supported between the top of the positioning pile m3 and the magnetic particles is located is horizontally and laterally crossed with the positioning groove, and the positioning groove can at least extend from a completely supported foaming circulation shaping hole 40 to an incompletely supported foaming circulation shaping hole 40. The incompletely supported foaming circulation shaping hole 40 is a foaming circulation shaping hole 40 that has a part that is not clamped by the top of the positioning pile m3 and the magnetic particles. Preferably, the straight groove or the cross groove horizontally penetrates the top of the support section m31 in the horizontal direction, so that the foaming material can also flow on the side. Of course, other implementations may also be used to allow the foaming flow shaping holes 40 to be filled with sufficient foaming material.
[0059] Preferably, in step S3, the temperature of the mold is controlled between 25-55 degrees Celsius, and the temperature of the foaming material during injection is controlled between 15-30 degrees Celsius. This can be selected independently according to the material. The general recommendation is that the initial injection temperature of the material is lower than the control temperature of the mold, which is a heating foaming process.
[0060] Furthermore, before step S2, the back side of the magnetic particles is prefabricated with a support and reinforcement anti-turnover gasket 5. In step S2, after the magnetic particles are inverted and set on the upper side of the continuous soft gasket 4, the support and reinforcement anti-turnover gasket 5 is on the upper side of the magnetic particles. The prefabricated connection can be to directly bond the back side of the magnetic particles to one side surface of the support and reinforcement anti-turnover gasket 5, so that after the magnetic particles are inverted, the support and reinforcement anti-turnover gasket 5 is close to it. The bonding method can be environmentally friendly glue, or if the support and reinforcement anti-turnover gasket 5 is made of plastic material, it can be slightly softened, and then the magnetic particles are placed on the support and reinforcement anti-turnover gasket 5, and the upper side of the support and reinforcement anti-turnover gasket 5 is cooled and solidified for connection. Of course, screws can also be used to directly pass through the support and reinforcement anti-turnover gasket 5 and lock it into the back side of the magnetic particles, and corresponding holes are opened on the back side of the magnetic particles. Of course, other methods can also be used for connection.
[0061] Furthermore, in step S2, a plurality of magnetic strips suspended in the pillow base foam molding groove m20 and located on the upper surface of the upper flexible limiting structure are also arranged in the pillow base foam molding groove m20 of the mold. Here, in step S2, the magnetic strips can be arranged first and then the magnetic particles, or the magnetic particles can be arranged first and then the magnetic strips, or the magnetic particles and magnetic strips can be arranged simultaneously or alternately. The magnetic strip can also be arranged to the positioning pile m3 through the positioning mold m4. Some of the magnetic positioning holes m40 opened on the positioning mold m4 are long rectangular. These holes are with the magnetic strip and are used for the magnetic strip to be placed from top to bottom for positioning. The difference is that the magnetic particles correspond to the positioning piles m3 one by one, one magnetic particle corresponds to one positioning pile m3, and the magnetic strip corresponds to multiple positioning piles m3. When arranged, the magnetic strip is also placed inverted on the positioning pile m3. The front edge of the magnetic strip is generally rounded or chamfered, and each magnetic strip is supported and positioned by a row of positioning piles m3 arranged at intervals on the left and right. The positioning piles m3 of each queue support and position one of the magnetic strips on the lower side, and preferably there are at least three positioning piles m3, which are located at the left end, right end and below the middle of a magnetic strip. The magnetic strip does not need to support the anti-flip gasket 5.
[0062] Preferably, in step S3, the foaming material is injected into the base foaming molding groove m20 through a syringe. The syringe can be an existing foaming material injection device, and the syringe can be operated manually or robotically to perform the foaming material injection operation.
[0063] Further, in step S3, the foaming material is injected into the substrate foaming molding groove m20 at a first feeding speed and submerges the upper flexible limiting structure; then the foaming material is injected into the substrate foaming molding groove m20 at a second feeding speed and submerges the magnetic particles; then the foaming material is injected into the substrate foaming molding groove m20 at a third feeding speed until the substrate foaming molding groove m20 is filled, and the first feeding speed is greater than the second feeding speed. Here, at the beginning of the first stage, it is necessary to feed at a faster speed to make the foaming material level. The leveling process automatically extends horizontally through the meridians of the upper flexible limiting structure to achieve better leveling. The aforementioned first, second, and third feeding speeds refer to the feeding speed of the entire syringe, because the syringe here will include multiple injection components, and the injection method of the syringe in each stage needs to be different as much as possible. For example, the syringe includes multiple injection guns or nozzles. Further, in the first stage, the syringe includes multiple injection guns for injecting foaming materials at the peripheral position of the substrate foaming molding groove m20. The injection gun sprays into the substrate foaming molding groove m20 at the interval between the periphery of the substrate foaming molding groove m20 and the periphery of the upper flexible limiting structure. At this stage, the injection speed of all injection guns involved in the syringe is usually 30 cm³ / s It is appropriate to arrange at least one injection gun on the front, back, left and right sides, until the foaming material submerges the upper flexible limiting structure and the injection gun is removed; in the second stage, the injection gun is transferred to the top of the magnetic particles, and the foaming material is injected into the magnetic particles. Since the number of magnetic particles is relatively large, the operation of the injection gun is relatively difficult. An upright nozzle p1 can be used, and the nozzle can be installed on a pipe rack p2. The number and position of the nozzles p1 installed on the pipe rack p2 correspond to the upper and lower positioning piles m3. The nozzle p1 sprays the foaming material at the center of the upper surface of the magnetic particles. This is to maintain the consistency of the injection pressure of each nozzle. This is suitable for the retractable positioning pile m3. The sensor of the positioning pile m3 detects the pressure on each magnetic particle and tries to maintain consistency so that it can be sprayed. Press the magnetic particles so that they can suppress the foaming material below them to a certain extent to achieve the initial foaming and exhaust effect. However, the injection pressure should not be too high, otherwise it will cause sputtering and overflow. If there is a magnetic strip, the injection pressure of the nozzle p1 sprayed on the upper surface of the magnetic strip should be kept consistent as much as possible, and it does not need to be consistent with the nozzle p1 pressure facing the magnetic particles. The process is suitable for pillows with relatively regular shapes. If it is an irregular pillow, such as a pillow with a large arc-shaped surface, then the height of the positioning pile m3 and the nozzle injection pressure can be adjusted according to the actual situation at this stage. Different parameters can be designed according to the position of each magnetic particle. The injection pressure is usually between several hundred and several thousand Pa. The overall injection speed at this stage is usually about 15 cm³ / s, and it is OK to wait until the foaming material submerges the magnetic particles.Then comes the third stage. At this time, nozzle p1 can still be used to inject foaming materials, but the number of nozzles p1 is less than that of the second stage. In the second stage, the number is similar to the number of positioning piles m3, so usually more than 20 are required, while in the third stage, generally only about 5 are required, and the outlet diameter of the nozzle p1 in the third stage must be larger than that of the nozzle p1 in the second stage. At this time, the injection pressure does not need to be as high as that in the second stage, as long as the outlet volume is large. The injection pressure is less than 100 Pa, but the outlet diameter needs to be much larger than that of the nozzle p1. The total injection speed is usually 15-20 cm³ / s It is appropriate to use left and right, and then in this stage, these nozzles p1 are set in the middle position of the front and back of the area where the magnetic particles are located and are arranged at intervals on the left and right. Then, these nozzles p1 can be used to divide the corresponding radiation areas. At this time, the pressure of each positioning pile m3 in each area can be detected, and the average pressure of the area can be calculated. If the pressure in a certain area is small, the discharge speed of the nozzle p1 in the area can be increased, and vice versa, it can be reduced, so that the pressure in each area is more uniform, and the filling material in each area is more uniform. Finally, the height position of the positioning pile m3 itself can be slightly adjusted, so that the density and uniformity of the final pillow can be more controllable and reasonable. When the three-stage foaming material fills the base foaming molding groove m20, the upper mold is closed, and the mold temperature is controlled according to the aforementioned temperature to perform molding. Generally, molding can be completed in 5-10 minutes, and then the water temperature of the temperature control mechanism can be cooled down for a few minutes, or the water can be drained and naturally cooled for about ten minutes, and then demolding is performed. Since the foaming material has good flexibility after foaming, it can be manually lifted out according to the aforementioned method or grabbed by existing equipment, which basically has no effect on the temporary hole structure. ;
[0064] Through the above production process, foam pillows with more stable, reliable and comfortable structures can be produced. The process is more controllable and more attention is paid to the details of pillow production. Moreover, it can be completed directly in one process without the need for turnover grooving, etc., which greatly improves the production efficiency and improves the quality.
[0065] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
