Technical Field
[0001] This invention relates to the field of pillow technology, and in particular to a production mold for a pillow that is easy to disassemble and repair. Background Technology
[0002] As people's living standards improve, their functional demands for pillows are becoming increasingly diverse. Smart pillows with functions such as music playback and magnetic therapy are gradually gaining popularity among consumers. The production process of these pillows requires the installation of junction boxes and functional devices. Many existing technologies employ post-molding designs such as slotting, without adequately optimizing the mold itself.
[0003] This results in numerous problems when using existing pillow production molds to produce pillows that can be installed and repaired. For example, the installation of junction boxes, the connection of wires, and the structural design for disassembly and repair are easily damaged, making it difficult to disassemble and repair the pillows in subsequent processes. This affects production efficiency and product quality, and also prevents the pillows from being reused effectively. Summary of the Invention

[0009] As a preferred embodiment of the present invention, the left and right widths of the front and rear embedded wire inserts, the left inlet / outlet inserts, the right inlet / outlet inserts, and the right inlet / outlet inserts gradually decrease from bottom to top, and the front and rear widths of the left and right embedded wire inserts gradually decrease from bottom to top.
[0010] As a preferred embodiment of the present invention, the plug-in block is fixed on the upper rear wall of the foaming tank and is used for the junction box to be inserted and positioned backward. An inner wire inlet slot is formed on the upper front part of the junction box, and an outer wire inlet guide positioning port is formed on the rear part of the junction box. The outer wire inlet guide positioning port can be inserted backward into the plug-in block.
[0011] As a preferred embodiment of the present invention, a wire groove filling piece is fixed on the lower surface of the upper mold, located behind the front and rear embedded wire plugs and capable of being inserted downward into the inner wire inlet slot. The front side of the wire groove filling piece contacts and abuts the rear side of the front and rear embedded wire plugs, and the bottom of the wire groove filling piece is higher than the bottom of the front and rear embedded wire plugs. An upward-facing mounting groove is formed on the junction box for mounting the control circuit board. The top of the groove wall of the mounting groove can contact and abut the lower surface of the upper mold.

Detailed Implementation
[0017] The present invention will be further described in detail below with reference to the accompanying drawings.
[0018] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
[0019] Example 1, as Figure 1-10 As shown, a pillow that is easy to disassemble and repair includes a pillow base 1. The pillow base 1 can be made of an existing shape and foamed. A left internal cavity 121 is formed inside the left side of the pillow base 1, a right internal cavity 122 is formed inside the right side of the pillow base 1, and a front internal cavity 111 is formed inside the front internal cavity 111. A magnetic rotating instrument 21 is embedded in the front internal cavity 111. The magnetic rotating instrument 21 can be an existing cylindrical miniature magnetic rotating therapy instrument. A left music player 22 is embedded in the left internal cavity 121, and a right music player 23 is embedded in the right internal cavity 122. The left music player 22 and the right music player 23 can be existing instruments with music playback functions, mainly used to play some sleep-aiding or resting music. The bottom of the pillow base 1 has a left inlet / outlet groove 102 that extends forward and backward and communicates vertically with the left inner cavity 121, allowing the left music player 22 to enter and exit. The bottom of the pillow base 1 also has a right inlet / outlet groove 103 that extends forward and backward and communicates vertically with the right inner cavity 122, allowing the right music player 23 to enter and exit. Furthermore, the bottom of the pillow base 1 has a front inlet / outlet groove 101 that extends forward and backward and communicates vertically with the front inner cavity 111. The front inlet / outlet groove 101, left inlet / outlet groove 102, and right inlet / outlet groove 103 all extend downwards to the outside of the pillow base 1, meaning they all connect downwards to the outside. When the pillow is placed upright... In this configuration, the left inner cavity 121 is positioned above the left inlet / outlet slot 102, the right inner cavity 122 is positioned above the right inlet / outlet slot 103, and the front inner cavity 111 is positioned above the front inlet / outlet slot 101. The left inner cavity 121, right inner cavity 122, and front inner cavity 111 are located within the upper and lower middle areas of the pillow base 1. Through the inlet / outlet slot design, the left music player 22 can be inserted into the left inner cavity 121 via the left inlet / outlet slot 102 for use, and can also be removed via the left inlet / outlet slot 102 for maintenance and replacement, making disassembly and maintenance very convenient. The design principle of the other inner cavities and inlet / outlet slots is similar, making it easy to maintain and replace the right music player 23 and the magnetometer 21. There are requirements regarding the width of the inlet / outlet slots; they cannot be too wide, otherwise the structure may become loose, which will be explained in detail later.
[0020] Preferably, the front-to-back length of the forward-exit groove 101, left-to-right-exit groove 102, and right-to-right-exit groove 103 should be controlled within 12 cm, preferably 5-8 cm, with around 6 cm being the most effective. The vertical dimensions of the forward-exit groove 101, left-to-right-exit groove 102, and right-to-right-exit groove 103, i.e., the groove depth, should be controlled within 8 cm, preferably 2-5 cm, with around 3 cm being the most effective. It is not advisable to make it too deep.
[0021] Furthermore, the original left and right widths of the lowest parts of the forward and outward slots 101, left and right, and right and right are all within 10 mm, preferably 1-5 mm, with around 2 mm being the best for use. The original left and right widths here refer to the initial left and right widths within the mold after molding. During use, due to the characteristics of the flexible material itself, and with a pillowcase covering the pillow base 1, the slots will deform and converge, reducing the width of the inlet and outlet slots. Generally, they can shrink by about half, or even stick to the surface, ensuring not only easy disassembly, repair, and replacement, but also maintaining the sealing and structural integrity for normal use. In this case, the pillow base 1 needs to be made of a flexible foam base, such as sponge foam or latex foam. This material, as mentioned above, has deformation resilience and a certain degree of adsorption, so if the slots are stuck to the surface, there is still a good structural sealing effect. The original left and right width of the lowest part is the opening of the inlet / outlet groove exposed at the bottom, which is the position that the human eye can see at a glance. It can be wider inwards, and does not have to be a regular rectangular groove. Therefore, the original left and right width of the front inlet / outlet groove 101, left inlet / outlet groove 102 and right inlet / outlet groove 103 can gradually increase from bottom to top, but the original front and back lengths from top to bottom should be consistent, and the groove depth lengths from front to back should also preferably be consistent. In this case, it is preferable that the front inlet / outlet groove 101, left inlet / outlet groove 102 and right inlet / outlet groove 103 are isosceles trapezoidal grooves and are inverted. This isosceles trapezoidal groove means the groove shape, that is, the shape of the cross section of these grooves perpendicular to the length direction. The perspective of this embodiment is the perspective when the pillow is placed upright. In this way, the left and right width of the inlet / outlet groove is smaller as it goes down, with a decreasing process, so that the left and right width gaps of the grooves at the bottom and outside of the pillow base 1 are relatively small. In this way, the integrity and structural compactness of the pillow can still be well guaranteed. Of course, the forward exit slot 101, the left entry / exit slot 102, and the right entry / exit slot 103 can also be regular rectangular slots, meaning the entire slot is a cuboid, which also has a good effect.
[0022] Preferably, the bottom of the pillow base 1 has front and rear wire grooves 11 for embedding and concealing the front and rear power supply lines, and left and right wire grooves 12 for embedding and concealing the left and right power supply lines. The front and rear wire grooves 11 and the left and right wire grooves 12 are arranged in a cross shape, that is, the center of the cross is connected. The groove shape of the front and rear wire grooves 11 and the left and right wire grooves 12 can refer to the rectangular grooves of the front-in-out groove 101, the left-in-out groove 102 and the right-in-out groove 103, or more preferably, the inverted isosceles trapezoidal grooves. The width and depth of the wire groove 12 can be consistent with the front-to-outlet groove 101, the left-to-outlet groove 102, and the right-to-outlet groove 103. However, the lengths of the front and rear buried wire grooves 11 and the left and right buried wire grooves 12 should be larger. The front and rear groove lengths of the front and rear buried wire grooves 11 should be controlled between 15 and 35 centimeters, with 20 centimeters generally being quite effective. The left and right groove lengths of the left and right buried wire grooves 12 can also be controlled between 15 and 35 centimeters, with 20 centimeters generally being quite effective. The intersection of the front and rear buried wire grooves 11 and the left and right buried wire grooves 12 is the preferred center position for both.
[0023] The above structural design is suitable for a pillow base 1 with a symmetrical overall structure, meaning that the external shape of the pillow base 1 is preferably mirror-symmetrical. This refers to the overall external outline and does not include the structure of grooves and holes, as some cases may require asymmetrical small designs such as individual holes. Furthermore, preferably, the cross-shaped position of the front and rear embedded wire grooves 11 and the left and right embedded wire grooves 12 is exactly below the center of gravity of the pillow base 1 or within a radius of 0.5 cm below it. In short, it should be as vertically aligned with the center of gravity of the pillow base 1 as possible for better structural cohesion, which is very beneficial for the compactness of a pillow base 1 with multiple grooves.
[0024] Furthermore, the left end of the left and right buried cable grooves 12 is connected to the left inlet / outlet groove 102 and is perpendicularly intersected. This connected structure design allows the left inlet / outlet groove 102 to expand better when taking out or putting in the left music player 22, and also makes it easier for the wires to be introduced into the left and right buried cable grooves 12 from the left inner cavity 121. Similarly, the right end of the left and right buried cable grooves 12 is connected to the right inlet / outlet groove 103 and is perpendicularly intersected. Of course, the left inlet / outlet slot 102 can be located on the left side of the left and right buried cable slots 12 and spaced apart. In this case, it is necessary to ensure that the depth of the left and right buried cable slots 12 can connect to the left internal cavity 121, and it is also necessary to ensure that the area of the left internal cavity 121 can be extended to a part that is exactly above a part of the left and right buried cable slots 12 and connected. In this way, after the left music player 22 and its cable are put into the left internal cavity 121 from the left inlet / outlet slot 102, the cable can be pulled from the left internal cavity 121 to the left and right buried cable slots 12, and the cable can be routed. The right inlet / outlet slot 103 on the right side can also be designed with the same structure as the left side, but the effect is not as good as the aforementioned method. The reason is that the music players used are generally flat structures. For example, the left music player 22 is flat, and the left inner cavity 121 is also flat. If the cable is to run directly from the left inner cavity 121 to the left and right cable trays 12, the left inner cavity 121 needs to be closer to the left and right cable trays 12 and connect with them. However, due to the shape of the left inner cavity 121, if the left inner cavity 121 is closer, more of its horizontal area will be above the left and right cable trays 12. The left music player 22 will also have a lot of its horizontal portion above the left and right cable trays 12. This has a significant impact on the cohesion between the walls of the long left and right cable trays 12. Therefore, the previous implementation method is more recommended. The design of the front side is different. Specifically, the forward slot 101 exists on the left or right side of the front and rear buried wire grooves 11, or on both sides. The front part of the front and rear buried wire grooves 11 is connected vertically to the front inner cavity 111. That is, there can be one or two forward slots 101, and they are located on the left and right sides of the front position of the front and rear buried wire grooves 11. In the case of two slots, the symmetry of the pillow base will be better, but the difference is not significant. Another advantage is that it can be operated from both sides.Here, the wiring directly runs through the front and rear embedded cable channels 11 and the front inner cavity 111. The reason for this is that the magnetic magnet 21 is a long, narrow strip, designed to extend horizontally, meaning its length aligns with the pillow's horizontal length. Correspondingly, the front inner cavity 111 is also a long, narrow inner cavity extending horizontally. Therefore, by being slightly closer to the front and rear embedded cable channels 11, the horizontal area occupied by the magnetic magnet 21 and the front inner cavity 111 doesn't increase significantly, thus minimizing the impact on the convergence of the front and rear embedded cable channels 11. Furthermore, the size of the space connecting the front and rear embedded cable channels 11 and the front inner cavity 111 only needs to facilitate wiring; otherwise, it doesn't need to be... The process is quite complex because the magnetic magnetizer 21 and its wiring are handled through the front and rear cable trays 101. This is because the front and rear cable trays 11 are located in the middle of the pillow, while the magnetic magnetizer 21 and the front inner cavity 111 are aligned horizontally. Therefore, it's inconvenient to insert the long magnetic magnetizer 21 horizontally into the front inner cavity 111 from the middle of the front and rear cable trays 11. For example, if the magnetic magnetizer 21 is inserted into the left half of the front inner cavity 111 from the front and rear cable trays 11, while the right half of the magnetic magnetizer 21 is outside the pillow base and tilted, the front and rear cable trays would need to be pried open to allow this half to enter the right side of the front inner cavity 111. The right side of the 11 section requires significant deformation of the pillow base near the right side of the front and rear embedded wire grooves 11. This ensures that the deformation is not insufficient or that excessive force could damage the pillow. The forward exit groove 101 is spaced apart from the front and rear embedded wire grooves 11, meaning it is not located in the center of the pillow but slightly to the left or right. This facilitates operation and prevents damage to the pillow. For example, if the forward exit groove 101 is on the left side of the front and rear embedded wire grooves 11, more than half of the magnetizer 21 can be inserted into the front inner cavity 111 first, while the remaining left side is shorter and can be inserted more easily. Slightly prying the forward slot 101 open to the left allows the remaining left side portion to enter the front internal cavity 111. Since the wires of the magnetometer 21 are typically connected in the middle, they are inserted along with the magnetometer 21 as it is inserted into the front internal cavity 111 to the right. After the magnetometer 21 is finally inserted into the front internal cavity 111, the wires can be pulled out from the connection point between the front and rear buried wire slots 11 and the front buried wire slots 11 for wiring. That is, the connection point between the front and rear buried wire slots 11 and the front internal cavity 111 is located at the left-right middle position of the front internal cavity 111 and the front part of the front and rear buried wire slots 11. This design is more reasonable and suitable for both structural protection and use.
[0025] Furthermore, the original left-right width of the lowest part of the front and rear buried wire grooves 11 and the original front-back width of the lowest part of the left and right buried wire grooves 12 are both within 10 mm, preferably 1-5 mm, with about 2 mm being the best for use. The width, depth, and shape of this groove are as described above, referring to the front-to-outlet groove 101, left-to-outlet groove 102, and right-to-outlet groove 103. In addition, the front and rear buried wire grooves 11 and the left and right buried wire grooves 12 all extend downwards to the outside of the pillow base 1, that is, they are exposed downwards. This facilitates operation, and due to the materials and other structural design, it ensures stability and compactness in use.
[0026] Furthermore, the left and right embedded wire grooves 12 have a left and right length that is one-quarter to one-half of the left and right length of the pillow base 1, and the front and back embedded wire grooves 11 have a front and back length that is one-third to one-half of the front and back length of the pillow base 1. This is a suitable ratio and has a good effect. The original height of the pillow base 1 is generally chosen to be between 8 and 20 centimeters, which is also the height of a conventional pillow. As mentioned above, the front and back embedded wire grooves 11 are located in the middle of the left and right sides of the pillow base 1 and divide the front inner cavity 111 into two symmetrical halves. The front and back outlet grooves 101 are located between the left and right center and the left end of the front inner cavity 111 or between the left and right center and the right end of the front inner cavity 111. This facilitates the placement and removal of the magnetizer 21, and the structure is centered, resulting in better balance.
[0027] Preferably, the average density of the area within 2 cm of the front inlet groove 101, left inlet groove 102, right inlet groove 103, front and rear buried wire grooves 11, and left and right buried wire grooves 12 in the horizontal direction of the pillow base 1 is 1.2-1.8 times, preferably about 1.5 times, the average density of other areas of the pillow base 1. This is to ensure that the density at the groove location is higher to guarantee sufficient strength and stability, because the grooved area is relatively weaker, and a higher density will make the stability more reliable. For example, the density of foam sponge and latex pillows is usually 40-100 kg / m³. For example, the density of high-quality pillows is relatively higher. In this case, the average density of the area within 2 cm of the front inlet groove 101, left inlet groove 102, right inlet groove 103, front and rear buried wire grooves 11, and left and right buried wire grooves 12 in the horizontal direction of the pillow base 1 can be controlled at about 90 kg / m³, while the average density of other areas of the pillow base 1 can be controlled at about 60 kg / m³. Here, the area within 2 cm in the horizontal direction can be the area within 2 cm of the equidistant solids of the horizontal cross-section of each groove, or it can be a circular area with a diameter of 2 cm centered on each part of the side wall of each groove. Such areas are different, but the effect is good, that is, the surrounding structure of the groove is optimized. The part of the pillow base 1 located above these grooves should also be strengthened in terms of structural density. That is, the average density of the area within 2 cm above the front and rear inlet grooves 101, left inlet groove 102, right inlet groove 103, front and rear buried wire grooves 11 and left and right buried wire grooves 12 is the same as the average density of the area within 2 cm in the horizontal direction of the pillow base 1 located within the front and rear inlet grooves 101, left inlet groove 102, right inlet groove 103, front and rear buried wire grooves 11 and left and right buried wire grooves 12. Alternatively, a broader approach can be adopted: the front-to-outlet groove 101, the left-to-outlet groove 102, the right-to-outlet groove 103, the front and rear wire-embedded grooves 11, and the left and right wire-embedded grooves 12. The average density of the portion of the pillow base 1 extending outward from the side wall and top wall of these grooves by at least 5 mm is 1.2-1.8 times the average density of other areas of the pillow base 1.
[0028] Furthermore, the forward and outward grooves 101, left and right, right and right, front and rear embedded wire grooves 11, and left and right embedded wire grooves 12 are all integrally formed grooves rather than cut grooves. That is, these grooves are formed during the foaming process, not cut later. This ensures better application in the scheme of this application and guarantees the effectiveness of use. Molded groove wall: Has a dense "skin" or "skin layer". Cut groove wall: Lacks the original dense skin; the cutting process is mechanical processing, directly exposing the internal structure of the foam. The groove wall surface has an open cell structure, exhibiting typical foam cross-sectional characteristics: rough, porous, open-cell, without a closed dense layer. Molded groove wall: Smooth and flat surface; color is usually the same as or slightly darker than the raw material. Due to increased density, the appearance quality is good, approaching the surface effect of injection molded parts. Cut groove wall: Rough and textured surface; the cell wall structure is clearly visible; the color may be slightly lighter, exposing the uncolored core or cutting dust residue. The edges are not as regular as the molded parts, with burrs or slight unevenness. Strength / Stiffness: The dense skin layer of the molded groove wall provides additional strength and stiffness support. Its edge sharpness and overall load-bearing capacity, especially at the edges, are superior to those of a cut groove wall, making it more suitable for the design of this application. Abrasion Resistance: The smooth, dense skin of the molded groove wall makes its abrasion resistance far superior to the open, rough surface of the cut groove wall. Edge Stability: The edges of the molded groove wall are covered by a dense skin, making them less prone to chipping or breakage. The edges of a cut groove wall are open pores, making them more susceptible to chipping, powdering, or edge collapse under friction or stress. Molded Groove: One-piece molding, no material waste. Cut Groove: Generates a large amount of cutting waste. The quality of the groove wall is significantly affected by the cutting tools, cutting method, and operator skill, resulting in relatively high processing costs.
[0029] Therefore, the pillow structure of this application, which facilitates easy assembly and disassembly, will frequently be used in the groove position. The advantage of the one-piece molded groove perfectly meets the needs of the design concept of this application, providing excellent practicality while effectively controlling costs. Moreover, combined with the aforementioned design of different densities, it greatly improves the overall performance and ease of assembly and disassembly of the pillow, integrating economy and practicality. Of course, the front content cavity 111, left content cavity 121, and right content cavity 122 are preferably formed directly during the foaming process, rather than being cut out in a later processing stage. The specific process will be described later.
[0030] Preferably, the front content cavity 111 is cylindrical and extends laterally with its axis in the left-right direction, while the left content cavity 121 and right content cavity 122 are horizontal disc-shaped with their axes in the up-down direction. That is, the axial length of the front content cavity 111 is greater than its diameter, giving it the appearance of a long cylindrical structure, while the axial lengths of the left and right content cavities 121 and 122 are less than their respective diameters, giving them the appearance of flat cylindrical structures. The diameter of the left content cavity 121 can be kept as consistent as possible with the front-to-back length of the left inlet / outlet slot 102, the diameter of the right content cavity 122 can be kept as consistent as possible with the front-to-back length of the right inlet / outlet slot 103, and the diameter of the front content cavity 111 can be kept as consistent as possible with the front-to-back length of the inlet / outlet slot 101. Of course, a slight deviation in size will not have a significant impact on the effect. The axial vertical height of the left and right inner cavity 121 and 122 can be selected to be no more than 2 cm, preferably around 1 cm. The axial horizontal length of the front inner cavity 111 can be selected to be 10-25 cm, preferably around 15 cm. The axial horizontal length of the front inner cavity 111 is preferably less than the length of the left and right embedded wire grooves 12. The overall dimensions of the left music player 22 and right music player 23 are kept as consistent as possible with the left and right inner cavity 121 and 122, respectively. The overall dimensions of the magnetizer 21 are kept as consistent as possible with the front inner cavity 111. Since the pillow matrix has good deformation capacity, slightly larger or smaller dimensions also have good effects. This design ensures compactness.
[0031] Preferably, a junction box 3 is embedded and connected to the rear side of the front and rear buried wire grooves 11 at the bottom rear position of the pillow base 1. The junction box 3 can be a plastic box, preferably placed in the foaming mold and directly embedded and connected to the foaming material during the foaming molding of the pillow base. The junction box 3 can adopt an existing structure, but for better wiring, it is best to optimize some groove positions. The front side of the junction box 3 forms an inner wire inlet groove 30 that communicates with the rear end of the front and rear buried wire grooves 11. The inner wire inlet groove 30 is at the bottom of the junction box 3 and extends front and back. The junction box 3 includes a main box body 34 and is preferably rectangular or approximately rectangular in shape. The bottom of the main box body 34 forms a downward-facing mounting groove 33. The mounting groove 33 is preferably also... The junction box 3 is rectangular and is used to install the control circuit board 31. The control circuit board 31 can be any existing control board capable of controlling the switching of electrical equipment. The wires of the magnetometer 21 enter the front and rear buried wire grooves 11 from the front inner cavity 111, then enter the inner wire inlet 30 and connect to the control circuit board 31, receiving power and control from it. The wires of the left music player 22 can enter the left and right buried wire grooves 12 from the left inlet 102, then turn into the front and rear buried wire grooves 11 at the intersection, and then also enter the inner wire inlet 30 and connect to the control circuit board 31. The right music player 23 is symmetrically wired to the left music player 22 on the rear side, also receiving power from the control circuit board 31. Therefore, the inner wire inlet 30 and the mounting groove 33 need to be connected front and rear, forming a convex shape. The main box 34 has a rectangular front guide wire section 35 integrally connected to its front side. An inner cable inlet slot 30 forms with the bottom of the front guide wire section 35 and connects front and back. The lower side of the inner cable inlet slot 30 is also open, facilitating subsequent cable insertion. Thus, the main box 34 and the front guide wire section 35 form a U-shaped structure. A U-shaped expansion connecting plate 341 is integrally connected to the top of the main box 34. The opening of the expansion connecting plate 341 faces rearward and is integrally connected to the left, front, and right sides of the top of the main box 34. This allows for better foaming and molding bonding with the foam material. Furthermore, the expansion connecting plate 341 has several vertically penetrating expansion connecting holes 342, essentially forming more channels for better integration with the foam material and ensuring the structural embedding stability. The rear of the main box 34 does not require further expansion, as it is already located at the back of the pillow.Instead, an external cable guide positioning port 32 is formed on the rear side of the junction box 3. This design can be implemented by integrally connecting a front-to-back extending guide head 320 to the rear side of the main box body 34. The guide head 320 has an external cable guide positioning port 32 that extends front-to-back and communicates with the mounting groove 33. The external cable guide positioning port 32 is for connecting external wires to the control circuit board 31. Since an external controller and an external power supply are generally required, the external controller and power supply need to be connected to the control circuit board 31 through the external cable guide positioning port 32 via the corresponding wires. 1. The cross-sectional shape of the guide head 320 can be rectangular or circular, preferably waist-shaped and horizontal, i.e., racetrack-shaped. The cross-sectional shape of the external cable guide positioning port 32 can be consistent with that of the guide head 320. The waist-shaped shape extends wider to the left and right to facilitate the access of multiple wires. Finally, it is preferable to equip the bottom of the main box 34 with a cover plate that covers the mounting groove 33. It can be detachably installed by means of a protruding snap-fit structure or plug-in structure, or by using existing structures such as screw locking. The cover plate serves to protect and support, and also prevents the control circuit board 31 from being exposed.
[0032] Preferably, the sidewalls of the front internal cavity 111 are interwoven with reinforcing mesh sleeves 24 for the magnetizer 21 to be fitted into. The reinforcing mesh sleeves 24 can be made of nylon or cotton mesh fabric. When open, the reinforcing mesh sleeves 24 are also cylindrical or nearly cylindrical flexible sleeves with an opening located at the forward / outward slot 101. This facilitates the placement and removal of the magnetizer 21. The reinforcing mesh sleeves 24 can be placed into the mold during foaming and directly connected to the foamed material, increasing structural strength. Because the magnetizer is relatively heavy and large, a better external support is preferred.
[0033] Furthermore, a heating element is laid on the front side of the upper surface of the pillow base. This heating element can be an existing heating pad with an internal electrically heated heating wire. Combined with the front-side magnetic actuator, it provides good performance in cold climates.
[0034] The design of the foam pillow structure described above enables disassembly, repair, and replacement during long-term use, which is impossible with existing technology. It causes minimal damage to the pillow, has a high reusability rate, is more energy-efficient and environmentally friendly, and is both practical and economical. Furthermore, it combines music-assisted sleep aids and dynamic magnetic rotating devices, which greatly enhance sleep and rest.
[0035] Example 2, as Figure 11-21As shown, a production mold for a pillow that is easy to disassemble and repair is provided. The mold in this embodiment can be used to produce the easy-to-disassemble and repair pillow in Embodiment 1. The pillow structure in this embodiment can refer to the pillow structure in Embodiment 1, and can be further optimized, and can also be used as a reference for Embodiment 1. However, the focus is still on the design of the mold.
[0036] The specific solution includes a lower mold 42 and an upper mold 41 that covers the upper side of the lower mold 42. The lower mold 42 and the upper mold 41 are made of existing steel or other metals. The basic external outline can use the existing shape. The main changes are to the internal structure and optimization of some details to form a production structure for a pillow that is easy to disassemble and repair. The upper mold 41 and the lower mold 42 can be simple openable and detachable structures or hinged structures. In the hinged structure, the front side of the upper mold is hinged to the front side of the lower mold, which can be manually pushed open and closed, which is relatively labor-saving. In the case of direct opening and closing, it is advisable for the upper mold to be connected to a lifting device, but the impact on mold opening is relatively small. These are all existing technologies and will not be elaborated here.
[0037] The lower mold 42 forms a foaming groove 420 for foaming the pillow base 1. The foaming groove 420 is the shape of the outer contour of the pillow base 1, and any existing shape can be used. The groove wall of the foaming groove 420 should be smooth and can be coated with a high-temperature resistant, non-stick coating for easy demolding. In this embodiment, the foaming groove 420 is an inverted pillow base shape, so the pillow description is inverted, and the perspective is inverted. Because during foaming, the foaming groove 420 is an inverted pillow base 1 shape, and the left and right directions are also opposite to when it is upright, but since the main left and right structures are symmetrical, it does not significantly affect the description. The front and back directions are the same as when it is upright.
[0038] More importantly, the lower mold 42 is fixed with a plug block 300 for positioning the junction box 3 inserted into the foaming groove 420. The junction box 3 is inserted into the plug block 300 for floating positioning. The lower surface of the upper mold 41 is fixed with front and rear buried wire inserts 51 for forming front and rear buried wire grooves 11, left and right buried wire inserts 52 for forming left and right buried wire grooves 12, left in and out inserts 53 for forming left in and out groove 102, right in and out inserts 54 for forming right in and out groove 103, and forward and out inserts 55 for forming forward and out groove 101. These inserts are the fillers used to form each groove during the foaming process. Because of the inserts, the foaming material will not enter the position of the inserts during the foaming process, thus forming the empty grooves in the pillow base 1. Therefore, the shape and size of the inserts are the same as the shape and size of each groove. In addition, it also includes a first simulated filling block 61 that can be placed in the foaming tank 420 during foaming to simulate the magnetometer 21 and form the front internal cavity 111, a second simulated filling block 62 that can simulate the left music player 22 and form the left internal cavity 121, and a third simulated filling block 63 that can simulate the right music player 23 and form the right internal cavity 122. In the mold, these simulated filling blocks are also formed into each internal cavity in the form of solids. The shape and size are consistent with the shape and size of each cavity, and are also consistent with the corresponding shape and size of the magnetometer 21, the left music player 22 and the right music player 23. However, they can be slightly larger or smaller. The deformation capacity of the foam material is still sufficient, with a large tolerance. It also simulates the magnetometer 21, the left music player 22 and the right music player 23 that need to be placed after subsequent molding. After molding is completed, these simulated filling blocks need to be removed and real magnetometer 21, left music player 22 and right music player 23 are placed in them. As mentioned in Embodiment 1, the slots and cavities need to be connected. Therefore, the left inlet / outlet insert 53 and the second simulated filling block 62 of the simulated left music player 22 are in vertical contact, the right inlet / outlet insert 54 and the third simulated filling block 63 of the simulated right music player 23 are in vertical contact, and the front inlet / outlet insert 55 and the first simulated filling block 61 of the simulated magnetometer 21 are in contact. The contact points are the connected points because the foam material cannot enter at the contact points to form an empty connected space. Similarly, the left inlet / outlet insert 53 and the left and right embedded wire inserts 52 are in horizontal contact, the right inlet / outlet insert 54 and the right and right embedded wire inserts 52 are in horizontal contact, and the front part of the front and rear embedded wire inserts 51 and the first simulated filling block 61 are in vertical contact. These positions are preferred to be connected. In some pillows, if the left inner cavity 121 is also connected to the left and right embedded wire inserts 52, the left and right embedded wire inserts 52 and the second simulated filling block 62 also need to be in contact vertically. This is selected according to the needs. This is the position of physical contact. In the pillow matrix, since there is no foam material, a connected space will be formed. Of course, the same is true for the right side.
[0039] Preferably, the left inlet / outlet insert 53 is fixed with a left pin 72 for inserting the second simulated filling block 62. The left inlet / outlet insert 53 can be made of existing metal materials such as steel and its surface is horizontal, or it can be understood as being upright. The left pin 72 is also made of metal materials such as steel and is connected and fixed to the lower side of the left inlet / outlet insert 53 by welding or integral molding process and extends vertically. There can be more than one left pin 72, for example, two pins spaced back and forth, which are inserted downward into the second simulated filling block 62 for connection and foaming. Similarly, the right in-out insert 54 is fixed with a right pin 73 for inserting the third simulated filling block 63, and the front in-out insert 55 is fixed with a front pin 71 for inserting the first simulated filling block 61. The right in-out insert 54 and the front in-out insert 55 can also be made of existing metal materials such as steel, and both sides are horizontal. The pins are also made of metal, and there can be more than one pin. The design can be similar to that of the left in-out insert 53 and the left pin 72 described above. Of course, after insertion, the aforementioned vertical contact positions must be maintained, for example, the left in-out insert 53 and the second simulated filling block 62 should be in vertical contact.
[0040] Preferably, the front and rear embedded wire inserts 51 are fixed with auxiliary pins 711 for connecting the first simulated filler block 61 together with the front pin 71. The front and rear embedded wire inserts 51 and the left and right embedded wire inserts 52 are also preferably made of metal such as steel and are upright, except that one extends front and rear and the other extends left and right. Since the magnetometer 21 is relatively heavy and its left and right extension length is relatively long, it is easy to be unstable and uneven when using the front pin 71 at the position of the front-to-rear insert 55 to connect the first simulated filler block 61, because the first simulated filler block 61 is also relatively long in left and right dimensions and relatively heavy in weight, mainly compared with the second and third simulated filler blocks. Therefore, higher stability of the connection is required. Since the front side of the aforementioned preferred front and rear buried wire grooves 11 and the front internal cavity 111 need to be connected for the transmission of the magnetic flux generator 21 wires, pins, i.e., auxiliary pins 711, can be arranged on the front and rear buried wire inserts 51. The auxiliary pins 711 can also be made of metal such as steel and fixed on the lower side of the front part of the front and rear buried wire inserts 51. There can also be two pins, one in front and one in back. However, it should be noted that the auxiliary pins 711 are preferably arranged side by side with the front pins 71, with the number and position corresponding one-to-one. This will result in higher insertion stability of the first simulated filling block 61 and can minimize the problem of positional misalignment. In addition, the front part of the front and rear buried wire inserts 51 and the first simulated filling block 61 also need to be in contact vertically to form a connection.
[0041] Preferably, the front and rear buried wire inserts 51 extend forward and backward, and the left and right buried wire inserts 52 extend left and right. The front and rear buried wire inserts 51 and the left and right buried wire inserts 52 intersect in a cross shape. The left inlet / outlet insert 53 contacts the left end of the left and right buried wire inserts 52 and extends forward and backward. The right inlet / outlet insert 54 contacts the right end of the left and right buried wire inserts 52 and extends forward and backward. The front inlet / outlet insert 55 extends forward and backward and is located on the left or right side of the front and rear buried wire inserts 51, or on both sides. These designs of the front and rear buried wire inserts 51 and the left and right buried wire inserts 52 are designed to correspond to the front and rear buried wire grooves 11 and the left and right buried wire grooves 12. They complement each other and must be consistent with the shape and size of the front and rear buried wire grooves 11 and the left and right buried wire grooves 12. The cross shape formed by the front and rear embedded wire inserts 51 and the left and right embedded wire inserts 52 can be formed by integral molding, or one insert can be divided into two segments and welded to the other insert. For example, the front and rear embedded wire inserts 51 can be divided into front and rear halves and welded to the middle of the front and rear parts of the left and right embedded wire inserts 52, respectively. Of course, other methods can also be used to achieve this structure. In addition, the number and position of the forward and outward slots 101 are configured accordingly.
[0042] Furthermore, the widths of the front and rear embedded wire inserts 51, the left inlet / outlet insert 53, the right inlet / outlet insert 54, and the right inlet / outlet insert 54 gradually decrease from bottom to top, while the widths of the left and right embedded wire inserts 52 gradually decrease from bottom to top. This design is also based on the shape and size of the grooves corresponding to each insert, that is, the groove shape can preferably be the isosceles trapezoidal groove mentioned in Embodiment 1. In this embodiment, it is an upright isosceles trapezoid rather than an inverted one, because in this embodiment, the pillow base is foamed and formed inverted in the mold.
[0043] Preferably, the plug-in block 300 is fixed on the upper rear wall of the foaming tank 420 for the junction box 3 to be inserted and positioned rearward. An inner wire inlet slot 30 is formed on the upper front part of the junction box 3, and an outer wire inlet guide positioning port 32 is formed on the rear part of the junction box 3. The outer wire inlet guide positioning port 32 can be inserted rearward into the plug-in block 300. The outer dimensions of the plug-in block 300 are consistent with the outer wire inlet guide positioning port 32. The plug-in block 300 can be made of steel or other metal structures and fixed to the upper rear wall of the foaming tank 420 by welding or other methods. The viewing angle here is inverted, so the inner wire inlet slot 30 appears to be on the upper side. The outer wire inlet guide positioning port 32 is not only used for subsequent wiring of external wires, but also serves as a positioning port. After being inserted rearward into the plug-in block 300, it floats on the upper rear side of the foaming tank 420, and when the pillow is placed upright after final molding, it is located on the lower rear side of the pillow.
[0044] Preferably, a wire groove filling piece 3000 is fixed on the lower surface of the upper mold 41, located behind the front and rear buried wire inserts 51 and capable of being inserted downward into the inner wire inlet slot 30. The front side of the wire groove filling piece 3000 contacts and abuts against the rear side of the front and rear buried wire inserts 51, and the bottom of the wire groove filling piece 3000 is higher than the bottom of the front and rear buried wire inserts 51. The wire groove filling piece 3000 is designed to prevent the inner wire inlet slot 30 from being filled with foam material, leaving space for wire entry. The height design creates a stepped structure after the upper mold is covered, limiting the inner wire inlet slot 30 to the junction box from the front. The wire groove filling piece 3000 is also made of metal such as steel, and its shape matches the shape of the inner wire inlet slot 30. It can be a cuboid or an isosceles trapezoidal groove. The groove depth is smaller than the front and rear buried wire grooves, and the width can be the same as the width of the front and rear buried wire grooves at the same horizontal position. The front and rear length should be shorter, generally 1-2 cm. Furthermore, the junction box 3 has an upward-facing mounting groove 33 for mounting the control circuit board 31. The top of the groove wall of the mounting groove 33 can contact and abut against the lower surface of the upper mold 41. The top of the groove wall of the inner wire inlet slot 30 can contact and abut against the lower surface of the upper mold 41. The rear side of the inner wire inlet slot 30 is connected to the front side of the mounting groove 33. The viewing angle of the pillow here is inverted, so the top and bottom positions are opposite to those in Embodiment 1. The top of the groove wall of the mounting groove 33 is also the top of the side wall of the main box 34, and the top of the groove wall of the inner wire inlet slot 30 is also the top of the side wall of the front wire guide portion 35. It is sealed by abutting against the lower surface of the upper mold 41 to prevent foam material from entering the mounting groove 33 and the inner wire inlet slot 30, thereby affecting subsequent wiring.
[0045] Preferably, the foaming groove 420 is also provided with upper and lower filling rods 56 for forming upper and lower through grooves 13 that run through the pillow base 1. During the foaming process, the bottom of the upper and lower filling rods 56 contacts the bottom of the foaming groove 420, and the top of the upper and lower filling rods 56 contacts the lower surface of the upper mold 41. The contact is in the state where the upper and lower mold covers are closed. The purpose of the upper and lower through grooves 13 is to allow the wires of external heating pads, massage pads, or other functional components laid on the pillow to be introduced through the upper and lower through grooves 13 to the bottom of the pillow so as not to affect the use and to make it neater. The upper and lower through grooves 13 can also be directly connected to the buried wire groove or the front inner cavity for wire insertion, or the wire can be inserted separately. The upper and lower filling rods 56 can be directly welded to the bottom of the foaming tank using metal or other fixing methods. In this way, when demolding, whether the upper mold moves up and down for demolding or is hinged and flipped open for demolding, the upper and lower filling rods 56 will not affect the demolding of the pillow base. If the upper and lower filling rods 56 are fixed to the lower side of the upper mold, then if it is a hinged flip-open demolding, the upper and lower filling rods 56 will rotate and then detach from the pillow base, resulting in lateral extrusion force that will deform the pillow base. In addition, the aforementioned pins are preferably positioned at the front of the corresponding inserts. In this way, if the upper mold is hinged, the impact will be relatively small when the rear side flips up to open the mold. For example, if the front pin 71, which is fixed on the upper and lower sides of the front and rear embedded inserts 51, is positioned slightly in front of it, then during demolding, since the first simulated filling block 61 is sealed in the front cavity by the foam molding, the front pin 71 will detach from the first simulated filling block 61 during the upward flipping process on the rear side of the upper mold. However, the flipping will cause rotation and there will be a displacement in the front-rear direction. But with the forward design, the front pin 71 will be positioned at the front of the foamed front exit groove 101. Therefore, when it flips up and swings, there is room to avoid it, and the impact on the pillow base is small. Of course, if the upper mold is opened and closed by vertical translation, there will be no impact.
[0046] If the pillow contains a reinforcing mesh cover 24, the first simulated filling block 61 is inserted into the reinforcing mesh cover 24 before foaming and molding. Then, the front pin 71 and the auxiliary pin 711 are inserted through the reinforcing mesh cover 24 and the first simulated filling block 61. The position of the front pin 71 should be the opening position in the reinforcing mesh cover 24. After molding, the reinforcing mesh cover 24 will be in the front cavity. After demolding, the first simulated filling block 61 can be easily removed from the opening position of the reinforcing mesh cover 24 at the front groove 101 and replaced with the magnetizer 21.
[0047] In addition, if there are magnetic particles in the upper part of the pillowcase base when it is placed upright, the existing design can be used. Supporting structures such as support rods are fixed at the bottom of the foaming groove 420 of the lower mold. Then, the magnetic particles are arranged on these supporting structures in a suspended state by adsorption or other means. After foaming and molding, the pillow is demolded, the supporting structures are separated from the magnetic particles, and there will be magnetic particles in the pillow. This is the existing technology and will not be described in detail.
[0048] Furthermore, the first simulated filler block 61 is cylindrical with its axis oriented left-right, while the second simulated filler block 62 and the third simulated filler block 63 are disc-shaped with their axes oriented up-down. The outer surfaces of the first simulated filler block 61, the second simulated filler block 62, and the third simulated filler block 63 are smooth and are all made of heat-insulating material. Their shapes and sizes have been mentioned above and are designed to match the various receiving cavities. Regarding the material and surface design, the first simulated filler block 61, the second simulated filler block 62, and the third simulated filler block 63 require materials that facilitate easy insertion of pins and also facilitate demolding. Therefore, a smooth surface is necessary. A recommended approach is to use foam material blocks, such as polystyrene foam (EPS) blocks or polyethylene foam (EPE) blocks, with a smooth plastic film, such as PET film or PVC film, covering the outer surface of the inner core. This facilitates both insertion and demolding. The shape of the inner core of these filler blocks is the same as the shape of the filler block itself; the outer film is generally less than 1 mm thick and can be ignored. The film can be directly blow-molded onto the inner core of each filler block or bonded on. Moreover, these materials are all heat-insulating, and the purpose of heat insulation is to reduce the impact on temperature control, because better temperature control will be implemented later.
[0049] Since the first simulated filling block 61 is cylindrical, the contact area between the upper side of the first simulated filling block 61 and the lower side of the forward / outward insert 55 is relatively small. One approach is to cut a small section downwards at the forward / outward groove 101 after molding, which causes less damage to the pillow and is still usable, but some damage will always occur. A better approach is to form a recessed contact groove 610 on the upper part of the first simulated filling block 61. The contact groove 610 allows for more contact between the lower side of the forward / outward insert 55 and the pillow. Two contact grooves 610 are needed because the front and rear buried wire grooves 11 and the front internal cavity 111 are also connected. The front and rear buried wire inserts 51 and the upper and lower sides of the first simulated filling block 61 also need to contact each other. The contact portion of the contact grooves 610 can be more, but since the front and rear buried wire grooves 11 and the front internal cavity 111 are connected for the entry and exit of wires, the contact portion can be less. Therefore, the depth of the contact groove 610 that the first simulated filling block 61 has with the front and rear buried wire inserts 55 is deeper than the contact groove 610 that it has with the front and rear buried wire inserts 51. In this way, the connected structure is optimized.
[0050] Preferably, the tops of the front and rear embedded wire inserts 51, left and right embedded wire inserts 52, left inlet / outlet insert 53, right inlet / outlet insert 54, and front inlet / outlet insert 55 are all fixedly connected with heat-conducting pillars 8 that can pass upward through the upper mold 41. The heat-conducting pillars 8 are made of the same material as the inserts and are fixed to the corresponding inserts by welding or integral connection. There can be multiple heat-conducting pillars 8 on each insert. The heat-conducting pillars 8 are surrounded by a heat-insulating sleeve 80. The heat-insulating sleeve 80 is cylindrical and made of heat-resistant plastic or rubber. Because these inserts are preferably individually temperature-controlled, the density distribution of the overall pillow matrix is different. The position of the insert is the position of the groove, which requires better density. The heat-insulating sleeve 80 serves two purposes: heat insulation and installation positioning. The upper mold 41 has an assembly hole 410 for the heat insulation sleeve 80 to be inserted and positioned. The heat insulation sleeve 80 is tightly tightened and fixed to the heat-conducting column 8 and the assembly hole 410 by an interference fit. Of course, the inner and outer sides of the heat insulation sleeve 80 can be coated with heat-resistant adhesive to make the connection with the assembly hole 410 and the heat-conducting column 8 more stable. The assembly hole 410 is a cylindrical hole of one size, through which both the heat-conducting column 8 and the heat insulation sleeve 80 can pass. Alternatively, two interconnected cylindrical holes, one smaller at the top and one larger at the bottom, can be formed to form an annular step. The heat insulation sleeve 80 is inserted into the larger cylindrical hole on the lower side from bottom to top and is limited. The heat-conducting column 8 can also extend upwards out of the upper mold 41 through the smaller hole at the top, but the heat-conducting column 8 cannot contact the small hole to conduct heat, or the thickness of the heat insulation sleeve 80 at that point is reduced to fit the small hole. Furthermore, an inner temperature control pipe 91 connected to the upper end of the heat-conducting column 8 and an outer temperature control pipe 92 located around the inner temperature control pipe 91 are installed on the upper side of the upper mold 41. The inner temperature control pipe 91 can be a water temperature pipe, which can be fixedly installed on the upper mold 41 in an existing manner, preferably a detachable fixing method. The inner temperature control pipe 91 can meander in the middle area of the upper mold, and ensure that at least part of its position can be vertically aligned with the front and rear embedded wire inserts 51, the left and right embedded wire inserts 52, the left inlet / outlet insert 53, the right inlet / outlet insert 54, and the front inlet / outlet insert 55, so that the heat-conducting column 8... The top of the heat-conducting column 8 is connected to the internal temperature control tube 91. The top of the heat-conducting column 8 can be connected to the internal temperature control tube 91 by welding or other methods. Since the internal temperature control tube 91 is used for independent temperature control of the insert, when installing the internal temperature control tube 91 on the upper mold 41, a heat insulation pad should be laid between the bottom of the internal temperature control tube 91 and the upper mold 41, or a plastic bracket with low thermal conductivity should be used for support before installation. That is, the internal temperature control tube 91 should avoid contact with the upper side of the upper mold to prevent heat conduction. The top of the heat-conducting column 8 can be installed in contact with the side of the internal temperature control tube 91. The heat-conducting column 8 and the corresponding insert should preferably be made of metal with good thermal conductivity. The internal temperature control tube 91 has an inlet and an outlet, which can be connected to the inlet and outlet water pipes respectively. The temperature of the internal temperature control tube 91 can be increased at an appropriate time to increase the density of the corresponding area and then immediately cool and solidify. The internal water supply can be a stable supply of hot and cold water.The upper mold 41 is connected to the external temperature control pipe 92 near the periphery. The external temperature control pipe 92 is used to control the overall temperature of the upper mold 41, which is the main temperature for foaming and molding. This ensures that the density of most areas of the pillow matrix is uniform and generally comfortable. The external temperature control pipe 92 also has inlet and outlet connections to the corresponding water inlet and outlet pipes.
[0051] In addition, if the front and rear embedded wire inserts 51, left and right embedded wire inserts 52, left inlet / outlet inserts 53, right inlet / outlet inserts 54 and the front inlet / outlet inserts 55 do not require temperature control, the tops of the front and rear embedded wire inserts 51, left and right embedded wire inserts 52, left inlet / outlet inserts 53, right inlet / outlet inserts 54 and the front inlet / outlet inserts 55 can be directly fixed to the lower side of the upper mold 41 by existing methods such as welding.
[0052] In addition, to allow the foaming material injection to occur while the mold is closed, an injection port can be created on the upper or lower mold, leading to the foaming tank, as is currently possible. This injection port is then connected to a foaming material injection pipe, which reduces the instability of the internal structure during mold closure. Alternatively, the mold can be closed after the foaming material has been injected, with the upper mold covering the lower mold downwards; this is also feasible.
[0053] In summary, the design of the entire mold enables the production of pillows that are easy to disassemble and repair. Moreover, the internal design of the mold is more comprehensive in terms of positioning, temperature control, and structural layout. It takes into account both production molding and demolding, resulting in excellent production efficiency and molding effect.
[0054] Example 3, as Figure 22 As shown, a manufacturing process for a pillow that is easy to disassemble and repair is presented. This embodiment is also a relatively professional manufacturing process based on the pillow of Embodiment 1 and the mold of Embodiment 2. The designed pillow structure and mold structure can be referred to Embodiments 1 and 2.
[0055] Specifically, it includes: The process includes the following steps: Step 1, the junction box 3 is positioned in the foaming tank 420 of the lower mold 42 of the production mold using the plug-in block 300. The junction box 3 has a wire inlet guide positioning port 32, which is inserted backward into the plug-in block 300. Below the upper mold 41, there are a first simulated filling block 61 for simulating the magnetometer 21, a second simulated filling block 62 for simulating the left music player 22, and a third simulated filling block 63 for simulating the right music player 23, which can enter the foaming tank 420. The connection is completed by using a pin plug. The upper mold 41 is in the open state; Step 2, foaming material is injected into the foaming tank 420 for foaming and molding. Existing sponge foaming materials or latex foaming materials can be used. In this step, the upper mold can be placed on top of the lower mold first, and then the foaming material is injected into the foaming tank 420 of the mold. This method requires an injection hole on the upper or lower mold connected to a foaming material injection pipe. Alternatively, the foaming material can be directly injected into the foaming tank 420 in the open state and then the upper mold can be closed. However, the former method is recommended. There will be no impact on the internal structure from closing the upper mold. Step 3: After foaming and molding, the original pillow is formed and demolded. Step 4: The first simulated filling block 61, the second simulated filling block 62, and the third simulated filling block 63 are removed from the pillow base 1 of the original pillow and replaced with simulated magnetometer 21, left music player 22, and right music player 23. Then, the wiring is connected to the junction box 3. The lower side of the upper mold 41 has a left inlet / outlet insert 53 for forming the left inlet / outlet slot 102 and a right inlet / outlet slot 103. As in the aforementioned embodiment, the pillow base, located at the positions of the three simulated filling blocks, will respectively form a front content cavity 111, a left content cavity 121, and a right content cavity 122. The front opening slot 101, the left opening slot 102, and the right opening slot 103 are respectively connected to the corresponding content cavities vertically. In this way, these slots facilitate the removal of the simulated filling blocks from each content cavity and the insertion of the actual magnetometer 21, the left music player 22, and the right music player 23.
[0056] Preferably, the lower side of the upper mold 41 also has front and rear wire embedding inserts 51 for forming front and rear wire embedding grooves 11 and left and right wire embedding inserts 52 for forming left and right wire embedding grooves 12. The front and rear wire embedding inserts 51 and the left and right wire embedding inserts 52 intersect in a cross shape. The left inlet / outlet insert 53 contacts the left end of the left and right wire embedding inserts 52 and extends back and forth. The right inlet / outlet insert 54 contacts the right end of the left and right wire embedding inserts 52 and extends back and forth. The front inlet / outlet insert 55 extends back and forth and is located on the left or right side of the front and rear wire embedding inserts 51 or on both sides. The specific structure here can be referred to the aforementioned embodiment.
[0057] Furthermore, a left pin 72 is fixed on the left inlet / outlet insert 53, a right pin 73 is fixed on the right inlet / outlet insert 54, a front pin 71 is fixed on the front inlet / outlet insert 55, and an auxiliary pin 711 is fixed on the front and rear embedded wire inserts 51. These pins are pre-fixed on the upper mold of the mold. In step 4, the left pin 72 is inserted to connect to the second simulated filling block 62, the right pin 73 is inserted to connect to the third simulated filling block 63, and the front pin 71 and the auxiliary pin 711 are inserted together to connect to the first simulated filling block 61. The upper side of the second simulated filling block 62 contacts and abuts the lower side of the left inlet / outlet insert 53, the upper side of the third simulated filling block 63 contacts and abuts the lower side of the right inlet / outlet insert 54, and the upper side of the first simulated filling block 61 contacts and abuts the lower side of the front inlet / outlet insert 55 and the front and rear embedded wire inserts 51. This method of pin insertion is faster and more convenient, and also facilitates demolding.
[0058] Preferably, in step 4, the first simulated filling block 61 is taken out from the forward exit slot 101 and placed into the magnetometer 21; the second simulated filling block 62 is taken out from the left inlet / outlet slot 102 and placed into the left music player 22; and the third simulated filling block 63 is taken out from the right inlet / outlet slot 103 and placed into the right music player 23. This is the replacement of the structure. The filling material in the foaming process is taken out and replaced with the actual functional device. Subsequent replacement and maintenance are also done in a similar way. The purpose of the inlet / outlet slot design is for this.
[0059] Preferably, in the pillow base 1, the filling position of the first simulated filling block 61 forms the front content cavity 111, the filling position of the second simulated filling block 62 forms the left content cavity 121, and the filling position of the third simulated filling block 63 forms the right content cavity 122. The front content cavity 111 is vertically connected to the front and rear inlet / outlet groove 101 and the front and rear buried wire grooves 11, respectively. The left content cavity 121 is vertically connected to the left inlet / outlet groove 102, which is horizontally connected to the left and right buried wire grooves 12. The right content cavity 122 is vertically connected to the right inlet / outlet groove 103, which is horizontally connected to the left and right buried wire grooves 12. In step 4, when connecting... During the wiring process, the wires of the magnetometer 21 are introduced from the front internal cavity 111 into the front and rear buried wire grooves 11 and then laid backward along the front and rear buried wire grooves 11 and connected to the junction box 3. The wires of the left music player 22 and the right music player 23 are first laid along the left and right buried wire grooves 12, and then transferred to the front and rear buried wire grooves 11 and laid sequentially and connected to the junction box 3. The junction box 3 has an internal wire inlet slot 30 that communicates with the front and rear buried wire grooves 11. These wires need to be connected to the corresponding terminals of the circuit control board in the junction box 3. This is the wiring guidance and wiring method of the internal components after molding. Of course, multiple strands of wires can be tied with cable ties and buried in the buried wire grooves.
[0060] Furthermore, the junction box 3 is equipped with a control circuit board 31. After demolding, the control circuit board 31 is installed and connected to the mounting slot 33 in the junction box 3. The control circuit board 31 is installed after the original pillow is foamed and molded. It can be fixed in the mounting slot 33 by screws or adhesive. The wires of the magnetizer 21, music player 22 and right music player 23 are connected to the control circuit board 31 through the inner wire inlet slot 30. The junction box 3 also has an outer wire inlet guide positioning port 32 on the rear side, which leads to the outside. The control circuit board 31 is also connected to an external connection wire through the outer wire inlet guide positioning port 32. The external connection wire is used to connect to external structures such as power supply and controller.
[0061] As a preferred option, in step 3, the demolding process first opens the upper mold 41, and the left pin 72, right pin 73, front pin 71 and auxiliary pin 711 detach from the pillow base 1. Then, the junction box 3 is pushed forward, and the rear side of the pillow base 1 is compressed and deformed. The junction box 3 detaches from the plug block 300, and then the entire original pillow can be taken out. This design of the plug block 300 and the junction box 3 not only completes the floating positioning of the junction box 3 in the foaming process, but also facilitates demolding. Moreover, it is an important part of the wiring composition, and the functional integration is highly optimized.
[0062] Preferably, step 1 also includes arranging a number of magnetic particles in the lower part of the foaming tank 420. This is the structure of the pillow matrix with magnetic particles. This can be achieved by placing the magnetic particles in the foaming tank as described above or in the prior art.
[0063] Furthermore, and more importantly, in step 2, the temperature of the foaming material during injection is controlled between 15-30 degrees Celsius, generally around 25 degrees Celsius, which yields good results. This refers to the temperature of the material itself. During the molding process, the overall temperature of the mold is controlled between 30-50 degrees Celsius. After the material is injected, the mold itself has temperature control, generally stabilizing slightly higher, typically around 40 degrees Celsius, which is quite effective. Then, what's particularly noteworthy is that the front and rear embedded wire inserts 51, left and right embedded wire inserts 52, left inlet / outlet insert 53, right inlet / outlet insert 54, and front inlet / outlet insert 55 are heated to above 80 degrees Celsius, but should ideally not exceed 130 degrees Celsius. Then, these are cooled to below 20 degrees Celsius, but ideally not below 10 degrees Celsius. This is a more unique aspect of this embodiment, where the temperature control of localized areas alters the pillow's density. First, the entire body is foamed at a low temperature and saturation. Then, the local area where the insert is located is heated to form a temperature gradient. The high temperature area will cause shrinkage, which will increase the density. Here, only the foam cells collapse and the whole body will not deform. Then, these local areas are cooled and shaped quickly. As a result, the density of the part near the molding groove is greater than the density of other areas of the pillow matrix, just as described in the structure of Example 1. The difference in density can be better applied to this kind of reusable pillow.
[0064] If the temperature is neither higher than 100 degrees Celsius nor lower than 0 degrees Celsius, the structural design in Example 2 is adopted, with local temperature control via an internal temperature control tube 91, which can be a water temperature tube. However, if the temperature is higher or lower, the internal temperature control tube 91 needs to be a temperature control tube with a medium that has stronger heating and cooling capabilities, or other existing heating and cooling equipment can be used to control the temperature and heat the heat-conducting column. However, in actual production, this is not very necessary, especially in cooling cases, where ambient temperature or slightly lower is generally sufficient, so no special cooling equipment is required. The overall temperature control of the mold can be achieved using the external temperature control tube 92 in Example 2, which can also be a water temperature tube. The temperature of the external temperature control tube 92 during the foaming process can be maintained by passing warm water through it, and subsequent cooling can be achieved by draining the water for natural cooling or by passing water below 20 degrees Celsius.
[0065] Of course, other implementation methods can also be adopted, so that the temperature control of the overall mold and the temperature control of the rear embedded wire insert 51, the left and right embedded wire inserts 52, the left in-out insert 53, the right in-out insert 54 and the front in-out insert 55 are performed separately, so as to obtain a pillow structure with different densities and reliable performance, which can be better applied to pillows that are easy to disassemble and repair.
[0066] Furthermore, after the front and rear embedded wire inserts 51, left and right embedded wire inserts 52, left inlet / outlet inserts 53, right inlet / outlet inserts 54, and front inlet / outlet inserts 55 are heated to the target temperature, they are held for 1-2 minutes. For example, if the target temperature is 80 degrees Celsius, they are heated to 80 degrees Celsius and held for 1-2 minutes. Then, cooling begins. After the front and rear embedded wire inserts 51, left and right embedded wire inserts 52, left inlet / outlet inserts 53, right inlet / outlet inserts 54, and front inlet / outlet inserts 55 are cooled to the target temperature, they are held for 1-2 minutes. For example, if the target temperature is 20 degrees Celsius, they are cooled to 20 degrees Celsius and held for 1-2 minutes. The overall foaming process of the mold is maintained for 10-20 minutes. Specifically, the overall temperature of the mold is rapidly reached to the target temperature, for example, 40 degrees Celsius, through temperature control. After maintaining this temperature for 1-2 minutes, heating and cooling operations are performed on the front and rear embedded wire inserts 51, left and right embedded wire inserts 52, left inlet / outlet inserts 53, right inlet / outlet inserts 54, and front inlet / outlet inserts 55. Simultaneously, the overall temperature of the mold is maintained at 40 degrees Celsius, for example, for 10 minutes. The heating and cooling of the inserts is only a localized temperature control process throughout the entire process. Then, the overall mold temperature is cooled for about 5 minutes. Here, the overall temperature refers to the temperature of the upper mold and the small mold, excluding the temperature of the inserts. Through this process, the density of the groove and the overall density can be effectively controlled during the foaming process, resulting in a pillow that is more suitable for disassembly and repair.
[0067] Through the above-mentioned process control, this type of detachable and repairable pillow can be manufactured relatively quickly, and various inlet and outlet grooves can be formed without the need for subsequent cutting processes. The overall structure and density design are more optimized, and the control of production costs and usage costs can be simplified, making it very practical and economical.
[0068] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
