Description

Technical Field

[0001] The present invention relates to the field of latex product processing, and more specifically, to a molding die for preparing a new latex material. Background Art

[0002] Latex generally refers to a colloidal emulsion formed by polymer microparticles dispersed in water, also known as latex, which is an important raw material for making products such as sponges, gloves, toys, pillows, and rubber hoses. A pillow made of natural latex has thousands of small mesh-shaped exhaust holes, which can dissipate the heat and moisture discharged by the human body, promote natural ventilation, provide a natural air-conditioning system, and keep the air inside the pillow fresh and healthy.

[0003] A latex pillow uses latex material as the raw material. First, the lower die base and the upper die base are closed to form a complete die, which is locked and sent to the production line. A hot raw material and an adhesive are injected into the die interior with a glue gun, then cooled and formed. Then the die is disassembled, the blank is taken out, and the burrs are trimmed to make a pillow piece.

[0004] However, it does not solve the problem that during the process of forming a new latex material through a die, when the die cools and forms the hot raw material, the die is then unlocked, and the upper die base and the lower die base are isolated from each other. When separating, it is not convenient for the upper die base to drive the blank upward. The blank gets stuck in the lower die base, partially exposed, with a narrow stress surface, and the blank is easily torn when being pulled, resulting in an increased damage rate during demolding of the die due to tearing. For this reason, we propose a molding die for preparing a new latex material. Summary of the Invention

[0005] 1. Technical Problem to be Solved

[0006] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a molding die for preparing a new latex material, which can achieve that when the upper die base demolds, it can drive the blank to separate from the lower die base upward, the blank has a wide stress surface, will not be torn due to pulling, and is convenient for reducing the damage rate during demolding of the die after forming the blank.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solutions.

[0009] A molding die for preparing a new latex material, comprising:

[0010] A lower die base, which is a cubic structure with a hollow interior and an open upper surface;

[0011] The middle spine part is integrally installed in the middle of the lower wall of the lower mold base, the upper surface of the middle spine part is an arc-shaped surface structure matching the pillow surface, and the two ends are respectively connected to the two sides of the lower mold base, and the interior of the middle spine part is provided with a heat dissipation mechanism;

[0012] An upper die seat, which is a cubic plate structure and is horizontally arranged above the opening of the lower die seat. A feeding mechanism is arranged in the middle of the upper surface of the upper die seat, and locking mechanisms are arranged at both ends of the upper die seat;

[0013] Side plates, two of which are vertically welded to a side of the upper die base close to the lower die base and are parallel to each other, and the sides of the two side plates that are away from each other are respectively adapted to the other two sides inside the lower die base;

[0014] Side ridge parts, the two side ridge parts are symmetrical to each other, the ends of the two side ridge parts that are far away from each other are respectively welded to the sides of the two side plates that are close to each other, the lower surfaces of the two side ridge parts are respectively flush with the lower surfaces of the corresponding side plates, and the upper surfaces are both flush with the arc surface of the middle ridge part;

[0015] The pattern template has an upper surface and a lower surface that are the same as the arc surface of the middle spine, and two ends of the pattern template are respectively attached to the sides of the two side panels that are close to each other. The upper surface of the pattern template is also provided with patterns that match the surface of the pillow.

[0016] Furthermore, the locking mechanism includes a flap in a cubic structure hinged at one end of the upper die base, an internal threaded tube is vertically welded to the lower surface of the flap, a limiting yoke welded to one end of the lower die base is arranged below the internal threaded tube, the limiting yoke is a concave structure with an opening direction away from the lower die base, a coaxial locking bolt is installed on the internal thread of the internal threaded tube, one end of the locking bolt extends out of the internal threaded tube and passes through the opening of the lower die base.

[0017] Furthermore, the feeding mechanism includes a glue injection hole vertically opened in the upper surface of the upper mold base, a coaxial hard tube is welded to the upper edge of the glue injection hole, a coaxial graphite tube is inserted into the interior of the glue injection hole, and one end of the graphite tube extends upward into the interior of the hard tube.

[0018] Furthermore, a plurality of coaxial support grooves are provided on the outside of the graphite tube at positions inside the hard tube, coaxial flange rings are inserted into the inside of the support grooves, and the outsides of the flange rings extend out of the support grooves and are welded to the inner wall of the hard tube.

[0019] Furthermore, the heat dissipation mechanism includes a heat dissipation cavity which is opened in the middle of the middle ridge portion and has a cubic structure. A ventilation window which is connected to the heat dissipation cavity is vertically opened in the middle of the lower surface of the lower mold base. The ventilation window also has a cubic structure and an opening area which is smaller than the cross-sectional area of the heat dissipation cavity. Between the two sides of the ventilation window, a plurality of air guide plates are distributed in a fan-shaped array along the opening downward.

[0020] 3. Beneficial effects

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] (1) This scheme first lays the pattern template on the upper surface of the two side ridges, then moves the upper die seat close to the lower die seat, splices them into a complete mold, and uses two locking mechanisms to lock the two ends of the mold respectively. Use a glue injection tube to inject a sufficient amount of high-temperature emulsion new material into the mold along the feeding mechanism. The internal heat is dissipated along the heat dissipation mechanism. After the blank is cooled and formed, the two locking mechanisms are released, the upper die seat is lifted upward, the side plates, side ridges and pattern template are moved upward, and the blank in the lower die seat is driven to move upward. When the upper die seat is demolded, it can drive the blank upward to separate from the lower die seat. The blank has a wide force-bearing surface and will not be torn due to pulling, which is convenient for reducing the damage rate of the mold to the blank after demolding.

[0023] (2) When locking the mold in this scheme, first flip the two flaps outward, rotate the locking bolt forward to extend it from the internal threaded tube, and then flip the two flaps inward to drive the two locking bolts to fit into the opening of the limit yoke. By reversely rotating the locking bolt and cooperating with the internal threaded tube to clamp the limit yoke under the action of friction, the lower mold base and the upper mold base are tightened, so that the two locking mechanisms can lock the two ends of the mold respectively. Conversely, loosen the locking bolt to release the locked state of the mold. The operation is simple, no time is wasted on demolding the blank, and no scratches are caused on the blank, so the safety is good.

[0024] (3) When the mold of this scheme arrives at the glue injection station, the glue gun is inserted into the upper end of the hard tube, and a sufficient amount of latex new material and adhesive is poured in, flowing downward into the mold along the inner wall of the graphite tube to prevent the blank from sticking to the glue injection hole and the hard tube after forming. The pulling effect of the upper die seat on the blank during demolding is effectively reduced to prevent the blank from being damaged. In addition, the blank has weak adhesion to the feeding mechanism, which is beneficial to reducing the amount of residual glue in the feeding mechanism.

[0025] (4) When the mold of this scheme is moved above the cooling fan of the latex new material production line, cold air is blown by the cooling fan and enters the cooling chamber along the ventilation window. The cold air is diverted by multiple air guide plates so that the cold air reaches every corner of the cooling chamber, thereby reducing the distance between the cold air and the blank, shortening the heat dissipation distance of the blank, and facilitating rapid cooling and molding of the blank.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0037] Example:

[0038] See also Figures 1-8 , a molding mold prepared from a new latex material, comprising:

[0039] The lower die base 1 is a hollow cubic structure with an open upper surface and an inner surface coated with a wear-resistant and high-temperature resistant anti-stick coating of SP-882;

[0040] The middle spine part 2 is integrally installed in the middle of the lower wall of the lower die base 1. The upper surface of the middle spine part 2 is an arc-shaped surface structure matching the pillow surface and the two ends are respectively connected to the two sides of the lower die base 1. The middle spine part 2 is provided with a heat dissipation mechanism inside and the outer surface is coated with SP-882 wear-resistant and high-temperature resistant anti-stick coating;

[0041] The upper die base 3 is a cubic plate structure, which is horizontally arranged above the opening of the lower die base 1. A feeding mechanism is arranged in the middle of the upper surface of the upper die base 3, and locking mechanisms are arranged at both ends of the upper die base 3. The outer surface is coated with SP-882 wear-resistant and high-temperature resistant anti-stick coating;

[0042] Side plates 4, two side plates 4 are vertically welded to a side of the upper die base 3 close to the lower die base 1 and are parallel to each other, and the two sides of the two side plates 4 that are away from each other are respectively adapted to the other two sides inside the lower die base 1, and the outer surfaces are coated with SP-882 wear-resistant and high-temperature resistant anti-stick coating;

[0043] Side ridge parts 5, the two side ridge parts 5 are symmetrical to each other, and the outer surfaces are coated with SP-882 wear-resistant and high-temperature resistant anti-stick coating, the ends of the two side ridge parts 5 that are far away from each other are respectively welded to the sides of the two side plates 4 that are close to each other, the lower surfaces of the two side ridge parts 5 are respectively flush with the lower surfaces of the corresponding side plates 4, and the upper surfaces are both flush with the arc surface of the middle ridge part 2;

[0044] The pattern template 6 has an upper surface and a lower surface which are the same as the arc surface of the middle spine portion 2. The two ends of the pattern template 6 are respectively attached to the sides of the two side panels 4 which are close to each other. The upper surface of the pattern template 6 is also provided with a texture 61 which is adapted to the surface of the pillow, and the outer surface is coated with SP-882 wear-resistant, high-temperature resistant and anti-stick coating. The pattern template 6 is made of fluororubber and can withstand the high temperature environment of the molding process without deformation.

[0045] When the present invention works, first place the pattern template 6 with its texture 61 facing upward on the upper surfaces of the two side ridge portions 5, align it with the outer sides of the side plates 4, and then move the upper die holder 3 closer to the lower die holder 1. The two side plates 4 slide down along the two sides inside the lower die holder 1 until the upper surfaces of the side ridge portions 5 and the middle ridge portion 2 are flush. Drive the side plates 4 and the side ridge portions 5 to completely sink into the lower die holder 1, so that the lower die holder 1 and the upper die holder 3 are spliced into a complete mold. Then use two locking mechanisms to lock the two ends of the mold respectively, and place it on the latex new material production line. After reaching the injection station, use an injection pipe to inject a sufficient amount of high-temperature emulsion latex new material into the mold along the feeding mechanism. Then move it above the cooling fan, and the internal heat dissipates along the heat dissipation mechanism. After the blank is cooled and formed, release the two locking mechanisms, lift the upper die holder 3 upward, move the side plates 4, the side ridge portions 5 and the pattern template 6 upward, drive the blank in the lower die holder 1 to move upward. When the upper die holder 3 is demolded, it can drive the blank to separate from the lower die holder 1 upward. The force-bearing surface of the blank is wide, and it will not be torn due to pulling, which is convenient for reducing the damage rate of the mold to the demolded blank after forming.

[0046] Refer to Figure 5 and Figure 7 , a plurality of positioning holes 7 are provided in the arc surface of the middle ridge portion 2 in the vertical direction. A plurality of protrusions 8 adapted to the positioning holes 7 are integrally installed on the lower surface of the pattern template 6. When the mold is closed, the pattern template 6 drives the protrusions 8 to sink into the corresponding positioning holes 7, and the pattern template 6 is supported in the horizontal direction through the positioning holes 7 and the protrusions 8, so as to perform positioning and prevent the pattern template 6 from being skewed in the lower die holder 1. Cooperating with the texture 61, a complete pattern of the pillow surface can be formed on the lower surface of the blank.

[0047] Refer to Figure 2 and Figure 6 , the locking mechanism includes a flap 9 with a cube structure hinged to one end of the upper die holder 3 through a hinge. An internally threaded pipe 10 is vertically welded to the lower surface of the flap 9. A limit joint fork 11 welded to one end of the lower die holder 1 is arranged below the internally threaded pipe 10. The limit joint fork 11 is a concave structure with an opening direction away from the lower die holder 1. A coaxial locking bolt 12 is threadedly installed inside the internally threaded pipe 10. One end of the locking bolt 12 extends out of the inside of the internally threaded pipe 10 and passes through the opening of the lower die holder 1. When the mold is locked, first turn the two flaps 9 outward, rotate the locking bolt 12 forward, extend it out of the internally threaded pipe 10, and then turn the two flaps 9 inward, drive the two locking bolts 12 to be stuck into the opening of the limit joint fork 11, and by rotating the locking bolt 12 in the reverse direction until the screw head of the locking bolt 12 abuts against the lower surface of the limit joint fork 11, and cooperate with the internally threaded pipe 10 to clamp the limit joint fork 11 under the friction action to tighten the lower die holder 1 and the lower die holder 1, which is convenient for the two locking mechanisms to lock the two ends of the mold respectively. On the contrary, loosen the locking bolt 12, and the locked state of the mold can be released. The operation is simple, the time for demolding the blank will not be wasted, and no scratches will be generated on the blank, and the safety is good.

[0048] Refer to Figure 2 and Figure 5 As shown in Figure 2 and Figure 5 , a slot 14 with a "mouth" - shaped structure is formed on the upper surface of the lower die base 1. There is a gap between the inner wall of the slot 14 and the lower die base 1. A sealing strip 13 adapted to the slot 14 is bonded to the lower surface of the upper die base 3. By inserting the sealing strip 13 into the slot 14, the gap at the connection between the lower die base 1 and the upper die base 3 can be sealed, improving the sealing performance of the mold and reducing the amount of glue overflow during feeding.

[0049] Refer to Figure 2 and Figure 4 As shown in Figure 2 and Figure 4 , two symmetrically arranged flange plates 15 are fixedly installed at both ends of the lower die base 1 through screws. The flange plates 15 are both of a porous plate structure, facilitating the penetration of screws. Two adjacent flange plates 15 are respectively located on both sides of the corresponding limit joint fork 11. Guide wheels 16 that rotate horizontally on a horizontal plane are rotatably installed on the side of the flange plates 15 away from the lower die base 1 through vertical rotating shafts. The length of the guide wheels 16 is greater than the length of the limit joint fork 11, which can form a shielding effect on the limit joint fork 11, avoiding the friction of the limit joint fork 11 in the new latex material production line. By pushing multiple guide wheels 16 on the new latex material production line, the mold can be straightened, converting sliding friction into rolling friction, and reducing the offset of the mold on the new latex material production line due to sliding friction.

[0050] Refer to Figure 5 and Figure 8 As shown in Figure 5 and Figure 8 , the feeding mechanism includes a glue injection hole 17 vertically formed in the upper surface of the upper die base 3. A coaxial hard pipe 18 is welded to the upper edge of the glue injection hole 17. A coaxial graphite pipe 19 is inserted into the interior of the glue injection hole 17. One end of the graphite pipe 19 extends upward into the interior of the hard pipe 18. When the mold reaches the glue injection station, a glue gun is inserted into the upper end of the hard pipe 18, and a sufficient amount of new latex material and adhesive are poured in, flowing downward along the inner wall of the graphite pipe 19 into the mold, preventing the blank from adhering to the glue injection hole 17 and the hard pipe 18 after forming, effectively reducing the pulling effect of the upper die base 3 on the blank during demolding and preventing the blank from being strained. Moreover, the adhesiveness of the blank to the feeding mechanism is weak, which is beneficial to reducing the amount of residual glue in the feeding mechanism.

[0051] Refer to Figure 5 and Figure 8 As shown in Figure 5 and Figure 8 , a plurality of coaxial support grooves 20 are formed at the position of the outer side of the graphite pipe 19 inside the hard pipe 18. Coaxial flange rings 21 are inserted into the interior of the support grooves 20. The outer sides of the flange rings 21 extend out of the interior of the support grooves 20 and are welded to the inner wall of the hard pipe 18. The part of the graphite pipe 19 located in the hard pipe 18 is supported vertically by the support grooves 20 and the corresponding flange rings 21, effectively removing the load of the flowing - down new latex material and adhesive on the hard pipe 18 and preventing the graphite pipe 19 from detaching from the hard pipe 18.

[0052] Refer to Figure 4 andFigure 5 , the heat dissipation mechanism includes a heat dissipation cavity 22 which is arranged in the middle of the middle backbone 2 and has a cubic structure. A ventilation window 23 communicating with the heat dissipation cavity 22 is vertically opened in the middle of the lower surface of the lower mold base 1. The ventilation window 23 also has a cubic structure and the opening area is smaller than the cross-sectional area of the heat dissipation cavity 22. A plurality of air guide plates 24 are distributed in a fan-shaped array along the opening downward between the two sides of the ventilation window 23. When the mold is moved above the heat dissipation fan of the latex new material production line, cold air is blown by the heat dissipation fan, enters the heat dissipation cavity 22 along the ventilation window 23, and is shunted by the plurality of air guide plates 24, so that the cold air reaches all corners of the heat dissipation cavity 22, reducing the distance between the cold air and the blank, shortening the heat dissipation distance of the blank, and facilitating the rapid cooling and forming of the blank.

[0053] Refer to Figure 2 and Figure 5 , a plurality of upright columns 25 staggered with the ventilation window 23 are vertically installed inside the heat dissipation cavity 22. Two groups of copper tubes 26 are respectively vertically arranged on both sides of the heat dissipation cavity 22 close to the side backbone 5. The two groups of a plurality of copper tubes 26 are distributed in a horizontal array and the opening directions are staggered with the upright columns 25. One ends of the copper tubes 26 all extend horizontally into the lower mold base 1. The plurality of upright columns 25 are used for supporting inside the middle backbone 2 to improve the bearing performance of the middle backbone 2, and the two groups of copper tubes 26 are used for diffusing the cold air and guiding it into the lower mold base 1, further increasing the heat dissipation area of the blank.

[0054] Refer to Figure 1 , Figure 2 and Figure 3 , two grips 27 are further arranged on the upper surface of the upper mold base 3 and are respectively located on both sides of the hard tube 18. Each of the two grips 27 is composed of two vertical rods and a cross bar welded between one ends of the two vertical rods. The other ends of the two vertical rods are vertically welded to the upper surface of the upper mold base 3. A coaxial roller 28 is sleeved outside the cross bar. The material of the roller 28 is rubber and it deforms under pressure. A plurality of weight reduction grooves 29 staggered with the glue injection holes 17 are also opened on the upper surface of the upper mold base 3. The weight reduction grooves 29 are all of cubic structure. While reducing the weight of the mold, the thickness of the upper mold base 3 can be reduced, facilitating the air in the weight reduction grooves 29 to absorb the heat of the blank conveniently. When holding the grips 27 with hands respectively, it is light in weight when lifted, and the roller 28 outside the grips 27 is used for buffering. The roller 28 deforms under pressure, which can relieve the pain in the hand caused by holding. After pulling the side backbone 5 upward to demold, push the blank horizontally. The adhesion area between the blank and the lower mold base 1 is small, and the pattern template 6 can be driven to leave the lower mold base 1 horizontally. Then, peel the pattern template 6 on the blank by hand to trim the blank.

[0055] Working principle: When the present invention is working, first, the pattern template 6 is laid with the texture 61 facing upwards on the upper surface of the two side ridges 5, aligned with the outer sides of the side panels 4, and then the upper mold base 3 is moved close to the lower mold base 1, and the two side panels 4 slide down along the two sides of the interior of the lower mold base 1 respectively, until the upper surface of the side ridges 5 is flush with the upper surface of the middle ridge 2, driving the side panels 4 and the side ridges 5 to completely immerse themselves in the interior of the lower mold base 1, so that the lower mold base 1 and the upper mold base 3 are spliced into a complete mold.

[0056] First, flip the two flaps 9 outward, rotate the locking bolts 12 forward to extend them from the internal threaded tube 10, and then flip the two flaps 9 inward to drive the two locking bolts 12 to fit into the opening of the limit yoke 11, and reversely rotate the locking bolts 12 until the screw heads of the locking bolts 12 are close to the lower surface of the limit yoke 11, and the internal threaded tube 10 is used to clamp the limit yoke 11 under the action of friction to tighten the lower die base 1 and the upper die base 1, so that the two locking mechanisms can lock the two ends of the mold respectively.

[0057] It is then placed on the latex new material production line. After arriving at the glue injection station, a sufficient amount of high-temperature emulsion latex new material is injected into the mold along the feeding mechanism using a glue injection tube. The mold is then moved to the top of the cooling fan, where cold air is blown by the cooling fan and enters the cooling cavity 22 along the ventilation window 23. The cold air is diverted by a plurality of air guide plates 24, so that the cold air reaches every corner of the cooling cavity 22, thereby reducing the distance between the cold air and the blank, shortening the heat dissipation distance of the blank, facilitating rapid cooling and molding of the blank, and dissipating the internal heat along the cooling mechanism.

[0058] After the blank is cooled and formed, the two locking mechanisms are released, the upper die base 3 is lifted upward, the side plates 4, the side ridge beams 5 and the pattern template 6 are moved upward, and the blank in the lower die base 1 is driven to move upward. When the upper die base 3 is demolded, it can drive the blank to separate upward from the lower die base 1. The blank has a wide force-bearing surface and will not be torn due to pulling, which facilitates reducing the damage rate of the mold to the blank after demolding after molding.

[0059] Finally, loosen the locking bolt 12 to release the locking state of the mold, without wasting time for demolding the blank and without scratching the blank. After demolding by pulling the side ridge beam 5 upward, push the blank in the horizontal direction. The adhesion area between the blank and the lower die base 1 is small, which can drive the pattern template 6 to leave the lower die base 1 laterally, and then peel off the pattern template 6 on the blank by hand to trim the blank.

[0060] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
