A beaded foam midsole encapsulation device

Abstract

This invention relates to the field of midsole processing technology, specifically to a beaded foam midsole coating device, comprising a base and a control panel mounted on the base. A lower mold is disposed on one side of the base, and an adsorption component is disposed within the lower mold to adsorb the placed film within the lower mold. A support is disposed on the base, and a hydraulic component is disposed on the support. An upper mold is disposed near the end of the hydraulic component close to the lower mold. This invention enhances the abrasion resistance of the side surface of the finished midsole. Simultaneously, during the entire processing, through the cooperation of a set annular bonding plate and an air extraction pipe, air is extracted from one side of the film after it has been placed, creating a pressure difference on one side of the film, which adsorbs the film onto the entire inner cavity of the lower mold. This facilitates the subsequent introduction of high-temperature steam into the entire mold, allowing the molten beaded foam to fuse together with the film.

Description

Technical Field

[0001] This invention relates to the field of midsole processing technology, specifically to a beaded foam midsole coating device. Background Technology

[0002] Beaded foam is a lightweight porous material formed by thermal bonding of countless microsphere-shaped foamed particles. First, thermoplastic polymer raw materials are made into microsphere particles filled with independent closed-cell air bubbles using supercritical fluid foaming technology. Then, these pre-foamed beads are filled into a mold, and the surface of the particles is melted and bonded together by high-temperature steam or hot pressing, and finally solidified into an integral foam with a three-dimensional internet-like structure.

[0003] When manufacturing shoe midsoles, this type of integral foam is an ideal material for high-performance applications such as sports shoe midsoles and packaging cushioning due to its lightweight, high resilience, excellent resistance to compression deformation, and fatigue resistance. During the manufacturing process, the foam beads are placed in the cavity of a mold, and then high-temperature steam is introduced to allow the foamed beads to stand in a constant temperature and humidity environment for a period of time. This allows the gas distribution to be even and the cell structure to be stable, ultimately forming a finished midsole with a shape consistent with the midsole, which is convenient for subsequent processing and use.

[0004] When the above process involves placing beaded foam into the mold for molding, the sides of the molded midsole will develop pores due to the inherent properties of the beaded foam as it melts together under high temperature and humidity. The appearance of these pores not only damages the appearance of the finished product, but also leads to insufficient wear resistance on the sides of the entire midsole, affecting the overall yield of the finished product. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a beaded foam midsole coating device that enhances the abrasion resistance of the midsole side of the finished product. Simultaneously, throughout the entire processing, the molds remain tightly fitted together, preventing the beaded foam inside the mold from cooling down due to gaps between the molds before complete melting, thus avoiding affecting the melting of the entire beaded foam.

The lower mold is provided with a locking component, and the upper mold is provided with a mating component. The mating component and the locking component are mated to lock the upper mold and the lower mold.

[0014] Preferably, the engaging assembly includes engaging seats arranged in an array within the upper mold, with the engaging seats and corresponding clamping plates on the same vertical line. A partition plate is provided inside the engaging seats, and a support plate is provided inside the engaging seats. The support plate is a combination of a U-shaped plate and a straight column, and the straight column has a cavity inside. Sliding rods are symmetrically and movably arranged on the support plate, and locking blocks are provided at one end of the two sliding rods facing each other.

[0015] Preferably, a third spring is sleeved on the outside of the sliding lever, a square pipe is provided on the side of the partition plate near the support plate, and the side of the square pipe away from the partition plate is fixedly connected to the support plate.

[0018] Preferably, the mating assembly includes mating chambers arrayed on the upper mold, with a mating plate disposed inside the mating chamber, and the overall shape of the mating plate being consistent with the arc-shaped plate. A mating component is movably disposed on the side of the mating chamber near the mating plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention places the film on the lower mold, and then the upper mold begins to descend so that the positioning component shapes the entire film. Through the cooperation of the set annular bonding plate and the air extraction pipe, air is extracted from one side of the film to create an air pressure difference on one side of the film. This causes the film to be adsorbed onto the entire inner cavity of the lower mold. This makes it convenient for the molten bead foam to be fused together with the film when high-temperature steam is introduced into the entire mold. The side of the midsole product formed after melting together has its wear resistance further enhanced under the action of the film.

[0021] 2. At the same time, when the upper mold begins to descend, the positioning plate can, with the cooperation of the clamping plate and the locking block, squeeze the clamping plate when the locking block is automatically reset by the elastic force of the third spring. This causes the clamping plate to drive the positioning plate to continue to rise a certain distance, thereby storing the entire positioning plate inside the upper mold and separating it from the lower mold, providing space for the entire bead foam to contact the film.

[0022] 3. When the upper and lower molds are closed together, the two semi-ring blocks in the locking and mating components will gradually rotate under their own pressure. Then, under the annular closure formed by the arc-shaped clamping plate and the mating clamping plate, the rotating semi-ring blocks will automatically reset under the action of the corresponding spring rod. After resetting, the two semi-ring blocks will lock with the arc-shaped clamping plate and the mating clamping plate, thereby further reinforcing the closure formed by the upper and lower molds. This reduces the risk of some gas escaping to the outside through the gap between the two when high-temperature steam is introduced into the mold, thus affecting the overall processing speed.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] Please see Figures 1 to 9This is the first embodiment of the present invention, providing a technical solution: a beaded foam midsole coating device, including a base 1 and a control panel 2 disposed on the base 1. The control panel 2 is used to control the entire processing. A lower mold 3 is disposed on one side of the base 1, which cooperates with an upper mold 6. By merging the two together, during subsequent midsole processing, beaded foam is filled into the cavity formed by the upper mold 6 and the lower mold 3. Then, high-temperature steam is supplied into the cavity to soften the surface of the beads, causing the beads to melt together. The mold 3 is equipped with an adsorption component 4, which is used to adsorb the placed film into the lower mold 3. The base 1 is equipped with a support 11, and the support 11 is equipped with a hydraulic component 5. The hydraulic component 5 is extended and retracted under the control of the control panel 2. Under the extension and retraction of the hydraulic component 5, the upper mold 6 near the lower mold 3 will be driven to form a close and sealed environment with the lower mold 3, which facilitates the subsequent processing and softening of the bead foam. The upper mold 6 is set at the end of the hydraulic component 5 near the lower mold 3. The upper mold 6 is used to cooperate with the lower mold 3 to form a sealed chamber.

[0040] The adsorption component 4 includes square sealing plates 41 symmetrically arranged on the lower mold 3. The inner wall of the square sealing plate 41 is filled with a ring of high-temperature resistant rubber gaskets. Through the fit between the square sealing plate 41 and the upper mold 6, a sealed environment is formed in the cavity between the molds, facilitating subsequent processing of the beaded foam. An annular bonding plate 42 is provided inside the lower mold 3, and the surface of the annular bonding plate 42 is perforated. The annular bonding plate 42 is consistent with the overall cavity shape of the lower mold 3, and there is a certain gap between the two. This gap is used to allow the film to be absorbed by the gaskets provided on the upper mold 6 when it is placed on the lower mold 3. Positioning component 7 positions and adheres the film, while suction pipe 43 inside lower mold 3 draws air to create a pressure difference on both sides of the film, thus adhering the film to the cavity of lower mold 3. Suction pipe 43 runs through the interior of lower mold 3 and is interconnected with annular bonding plate 42. The end of suction pipe 43 away from annular bonding plate 42 is connected to suction equipment, which is controlled by control panel 2. When suction equipment is activated, a certain pressure difference is created on one side of the cavity of lower mold 3 where annular bonding plate 42 is located, and the film is adsorbed by the pressure difference.

[0041] The lower mold 3 has an array of engaging grooves 31. A support sleeve 32 is movably arranged on the lower mold 3, and the support sleeve 32 is located inside the engaging groove 31. The support sleeve 32 is T-shaped, and the section parallel to the base 1 is hollow. A torsion spring is symmetrically arranged inside. The torsion spring cooperates with the engaging plate 33, so that the engaging plate 33 can automatically reset and clamp and position the film placed on the surface of the lower mold 3. The engaging plate 33 is movably arranged on the support sleeve 32, and the engaging plate 33 is rotatably connected to the support sleeve 32. The engaging plate 33 is in contact with the torsion spring inside the support sleeve 32. In the initial state, the torsion spring is in a relaxed state. When the engaging plate 33 starts to rotate, it will drive the torsion spring to rotate. Under the rotation of the torsion spring, a certain amount of elastic force is stored. When the operator releases the engaging plate 33, the engaging plate 33 can automatically reset under the action of the torsion spring.

[0042] A sliding groove 34 is provided on the side of the locking plate 33 near the lower mold 3, and a hinge is provided inside the sliding groove 34. A telescopic rod 35 is movably provided on the side of the locking groove 31 near the locking plate 33, and one end of the telescopic rod 35 is rotatably connected to the hinge. The telescopic rod 35 is used for extension and retraction. When the locking plate 33 starts to rotate, the telescopic rod 35 will extend a certain distance to ensure that the telescopic rod 35 can continue to maintain the locking and sliding relationship with the locking plate 33 when the locking plate 33 rotates. A first spring 351 is sleeved on the outside of the telescopic rod 35, and the first spring 351 is located on the telescopic rod 35. In the initial state, the first spring 351 will provide a certain support for the locking plate 33, so that the locking plate 33 is in a horizontal state, and the entire locking plate 33 is slightly... The plate is positioned above the surface of the lower mold 3. While ensuring a certain clamping effect on the film, it also prevents excessive clamping that could cause the film to break. A fixed rod 36 is provided on one side of the telescopic rod 35. A placement seat 361 is movably provided at the end of the fixed rod 36 away from the telescopic rod 35. The placement seat 361 has a cavity inside that engages with the fixed rod 36. The placement seat 361 is used to fix the lower mold 3. Through the fixed connection between the placement seat 361 and the lower mold 3, the movement between the fixed rod 36 and the telescopic rod 35 is limited. A second spring 362 is sleeved on the outside of the fixed rod 36. The second spring 362 is used to provide the elastic force required for reset. When the telescopic rod 35 is reset, it can also assist in the horizontal reset of the entire locking plate 33.

[0043] The locking plate 33 is symmetrically provided with locking rods 331, and the locking groove 31 is symmetrically provided with locking guide rails 332. The locking guide rails 332 and the locking rods 331 are locked and slid together. The upper mold 6 is movably provided with a positioning component 7 on the side close to the lower mold 3. The positioning component 7 is used to position the placed film against the inner wall of the cavity of the lower mold 3. The upper mold 6 is provided with telescopic sleeve plates 61 on the side away from the lower mold 3.

[0044] First, the film is placed on the surface of the lower mold 3. The film is positioned and clamped by the clamping plate 33 on the surface of the lower mold 3. After clamping, the beaded foam particles to be processed are filled into the cavity of the lower mold 3. At this time, the film will slide into the cavity of the lower mold 3 under the pull of the particles. At the same time, the film will also reduce the overall falling speed under the action of the clamping plate 33. Then, the hydraulic component 5 on the bracket 11 is activated through the control panel 2, so that the hydraulic component 5 drives the upper mold 6 to begin to descend. During the descent of the upper mold 6, the positioning component 7 will shape the entire film, so that the overall shape of the film is consistent with the shape of the lower mold 3. The lower mold 3 has a consistent cavity shape. When the upper mold 6 and the lower mold 3 are completely fitted together, a stable fixed locking state is formed by the locking component 9 on the lower mold 3 and the mating component 10 on the upper mold 6. Then, the external suction device connected to the suction pipe 43 can be activated to generate a pressure difference on one side of the film, causing the film to be adsorbed into the cavity of the lower mold 3. Then, the suction device can be turned off and the external high-temperature steam conveying device can be turned on. Through the conveying pipe on the upper mold 6, high-temperature steam is conveyed to the cavity between the upper mold 6 and the lower mold 3 to process the placed beaded foam, so that it finally becomes the insole of the finished product.

[0045] Example 2

[0046] Please see Figures 1 to 10 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0047] The positioning component 7 includes a movable collar 71 movably disposed in the upper mold 6, with a throat-shaped groove extending through its interior. The movable collar 71 is rotatably connected to the upper mold 6, allowing it to rotate freely. A sliding sleeve rod 72 is movably disposed inside the movable collar 71, consisting of a straight rod and a helical rod. When the upper mold 6 begins to descend, causing the positioning plate 73 at one end of the sliding sleeve rod 72 to contact the film laid on the surface of the lower mold 3, the positioning plate 73 presses down on the film, allowing it to enter the cavity of the lower mold 3. Once inside the cavity, an external air extraction device changes the air pressure on one side of the film, causing it to adhere to the cavity of the lower mold 3 and slide... A positioning plate 73 is provided at the end of the sleeve rod 72 away from the movable collar 71. The positioning plate 73 is consistent with the shape of the lower mold 3 cavity. The positioning plate 73 is an open ring plate. By conforming to the shape of the lower mold 3 cavity, the positioning plate 73 can press down on the laid film as it descends, so that the film adheres to the lower mold 3 cavity. A clamping plate 74 is symmetrically provided on the positioning plate 73. The clamping plate 74 is inclined and has a V-shaped arc angle on the side of the clamping plate 74 near the upper mold 6. This allows the clamping plate 74 to lock with the locking component 8 on the upper mold 6 and store the positioning plate 73 inside the upper mold 6 as the positioning plate 73 gradually shortens the distance between itself and the upper mold 6.

[0048] The upper mold 6 is provided with a locking component 8, which is used to lock the clamping plate 74 on the upper mold 6. The lower mold 3 is provided with a locking component 9, and the upper mold 6 is provided with a mating component 10. The mating component 10 and the locking component 9 are mated to lock the upper mold 6 and the lower mold 3.

[0049] The engaging assembly 8 includes engaging seats 81 arrayed within the upper mold 6, with the engaging seats 81 and corresponding clamping plates 74 aligned vertically. One side of each engaging seat 81 has an open slot to facilitate the entry of the clamping plate 74, allowing it to smoothly enter without obstruction. A partition plate 82 is provided inside the engaging seat 81 to support the square pipe 821 within it. A support plate 83 is also provided inside the engaging seat 81; this support plate 83 is a combination of a U-shaped plate and a straight column, with a cavity inside the straight column. Sliding rods 84 are symmetrically and movably mounted on the support plate 83. The sliding lever 84 has a slot on its surface, which engages with the support plate 83. This prevents the sliding lever 84 from rotating when it is displaced, thus avoiding interference with the locking block 85 at one end of the sliding lever 84. Both sliding levers 84 have locking blocks 85 at their opposite ends. These locking blocks 85 engage with the clamping plate 74. When the clamping plate 74 enters the slot of the engaging seat 81 and contacts the locking block 85, the locking block 85 resets under the action of the third spring 86 after the clamping plate 74 moves to a predetermined position. This allows the clamping plate 74 to continue rising a certain distance and be stored inside the upper mold 6.

[0050] A third spring 86 is sleeved on the outside of the sliding clamping rod 84. The third spring 86 provides elastic force. After the clamping plate 74 reaches the predetermined position, the elastic force stored in the third spring 86 can drive the locking block 85 to press the clamping plate 74, causing the clamping plate 74 to move a certain distance and be stored in the upper mold 6. A square pipe 821 is provided on the side of the partition plate 82 near the support plate 83, and the side of the square pipe 821 away from the partition plate 82 is fixedly connected to the support plate 83. The square pipe 821 is used to communicate with the cavity section of the straight column on the support plate 83. A fixed limiting rod 831 is provided inside the support plate 83, and the fixed limiting rod 831 is located inside the straight column section of the support plate 83. The fixed limiting rod 831 is inside the straight column section of the support plate 83, dividing the groove inside the straight column section, so that when the mold is filled with... When high-temperature steam is filled into the support plate 83, the residual moisture in the steam will not enter the other side of the straight column section. The entire fixed limit rod 831 is made of copper material with high thermal conductivity to transfer the temperature of the high-temperature steam. The support plate 83 is equipped with a conveying straight rod 832, and the conveying straight rod 832 has a cavity inside that fits and slides with the fixed limit rod 831. In the initial state, there is a certain space between the conveying straight rod 832 and the fixed limit rod 831. A helium-filled airbag is set in this space, and one end of the airbag is fixedly connected to the conveying straight rod 832, and the other end is fixedly connected to the fixed limit rod 831. The entire airbag has a certain degree of extensibility, so that the overall volume will expand after the helium is heated, thereby pushing the conveying straight rod 832 to move.

[0051] A fixed plate 833 is provided at the end of the conveying rod 832 away from the support plate 83. A limit guide rail 834 is symmetrically provided on the fixed plate 833, and the limit guide rail 834 engages and slides with the corresponding locking block 85. The limit guide rail 834 is obtuse-angled, which is used to drive the corresponding locking block 85 to open to both sides after the conveying rod 832 starts to move. After opening to a certain position, the continued movement of the conveying rod 832 will limit the locking block 85 to the current position and prevent it from moving.

[0052] During use, as the upper mold 6 begins to descend, the lowest positioning plate 73 gradually approaches the surface of the film and eventually contacts it, compressing the film to form a cavity consistent with that of the lower mold 3. Simultaneously, the clamping plate 74 on the positioning plate 73 contacts the locking block 85 inside the locking seat 81. Under the action of the inclined surface on one side of the locking block 85, after the clamping plate 74 pushes open the locking block 85, the clamping plate 74 will begin to contact the inclined surface of the locking block 85. At the same time, with the elastic force of the third spring 86, the locking block 85 is reset. The reset locking block 85 will continue to drive the clamping plate 74 to rise. Finally, after the upper mold 6 moves to the designated position, the positioning plate 73 can continue to move upward a distance under the action of both, and the entire positioning plate 73 can be stored inside the upper mold 6, avoiding any impact on the processing of bead foam.

[0053] The remaining structure is the same as that in Example 1.

[0054] Example 3

[0055] Please see Figures 1 to 13 This is the third embodiment of the present invention, which differs from the first and second embodiments in that:

[0056] The locking assembly 9 includes protective chambers 91 arrayed on the lower mold 3. An arc-shaped retaining plate 92 is provided on the side of the protective chamber 91 closest to the lower mold 3. A semi-circular retaining block 93 is movably disposed on the side of the protective chamber 91 closest to the arc-shaped retaining plate 92, and the semi-circular retaining block 93 is rotatably connected to the protective chamber 91 via a fixed rod. A locking push plate 94 is provided on one side of the semi-circular retaining block 93, and the locking push plate 94 is fixedly connected to the semi-circular retaining block 93. One end of a spring pull rod 95 disposed inside the protective chamber 91 is hooked onto the locking push plate 94. When pressed by the mating block on the upper mold 6, the two semi-ring blocks will press against each other and begin to rotate. When the upper mold 6 and the lower mold 3 are fully fitted together, the two semi-ring blocks will reset under the action of the corresponding spring rod 95. This resets the two semi-ring blocks and locks them with the arc-shaped clamping plate 92 that is spliced ​​into a ring shape, thus creating a stable locking state between the upper mold 6 and the lower mold 3. A spring rod 95 is movably provided on one side of the locking push plate 94, and the other end of the spring rod 95 is hinged and locked to the protective chamber 91. A fixed locking plate 96 is movably mounted on the side of the push plate 94 near the protective chamber 91. The fixed locking plate 96 is located on the side of the protective chamber 91 away from the locking push plate 94 and is fixedly connected to the semi-ring block 93. The fixed locking plate 96 is fixedly connected to the fixing rod on the semi-ring block 93, so that the fixed locking plate 96 can rotate synchronously when the semi-ring block 93 rotates. A square slot 961 is provided on the side of the fixed locking plate 96 away from the protective chamber 91. A plug-in plate 97 is movably mounted on the side of the protective chamber 91 near the fixed locking plate 96. The plug-in plate 97 is F-shaped. A push-pull plate 98 is provided on the side away from the protective chamber 91. The push-pull plate 98 is used to move the plug-in plate 97 by pressing the push-pull plate 98 when the upper mold 6 and the lower mold 3 are separated. Under the F-shaped area of ​​the plug-in plate 97 near the square slot 961 on the fixed locking plate 96, the square slot 961 is first leveled. Then, the support plate on the upper part of the plug-in plate 97 is inserted into the square slot 961, so that the straight surface of the semi-ring block 93 is parallel to the arc-shaped plate 92 after rotation. At this moment, the upper mold 6 and the lower mold 3 can begin to separate.

[0057] The mating component 10 includes mating chambers 101 arrayed on the upper mold 6. A mating plate 102 is provided inside the mating chamber 101, and the overall shape of the mating plate 102 is consistent with the arc-shaped plate 92. A mating part 103 is movably provided on the side of the mating chamber 101 near the mating plate 102. The mating part 103 is composed of identical semi-ring blocks 93, locking push plates 94 and spring rods 95, so that when the two identical semi-ring blocks 93 are attached, they will form a circular shape and form an annular groove with the mating plate 102 and the arc-shaped plate 92, which will be locked by the action of the two spring rods 95.

[0058] When the upper mold 6 descends and contacts the lower mold 3, the arc-shaped clamping plate 92 on the lower mold 3 and the mating clamping plate 102 on the upper mold 6 will contact each other first, gradually splicing together to form an annular groove. The two semi-annular clamping blocks 93 respectively set on the upper mold 6 and the lower mold 3 will start to rotate under mutual pressure. When the two semi-annular clamping blocks 93 are spliced ​​into a circle, the two rotating semi-annular clamping blocks 93 will be reset under the action of the corresponding two spring pull rods 95. The reset two semi-annular clamping blocks 93 will form a locking state with the spliced ​​arc-shaped clamping plate 92 and the mating clamping plate 102, which will strengthen and stabilize the fit between the upper mold 6 and the lower mold 3. At the same time, the springs used above are all made of high-temperature resistant materials to avoid the high-temperature environment from affecting the service life of the springs.

[0059] The remaining structures are the same as those in Examples 1 and 2.

[0060] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
