Description

Technical Field

[0001] The invention relates to the technical field of midsole processing, in particular to a bead foam midsole coating device. Background Art

[0002] Bead foam is a lightweight porous material formed by thermally bonding countless microspherical foamed particles. It first uses supercritical fluid foaming technology to make thermoplastic polymer raw materials into microspherical particles filled with independent closed-cell bubbles. These pre-foamed beads are then filled into a mold. High-temperature steam or hot pressing is used to melt the surface of the particles and bond them to each other. Finally, they are solidified and formed into an integral foam with a three-dimensional internet-like structure.

[0003] When this integral foam is used to prepare shoe midsoles, it is an ideal material for high-performance fields such as sports shoe midsoles and packaging cushioning because of its overall structure, which is lightweight, highly resilient, and has excellent resistance to compression deformation and fatigue resistance. During preparation, the beaded foam is placed in the cavity of the 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, so that the gas distribution is balanced and the bubble structure is stable, and finally a midsole product with the same shape as the midsole is formed, which is convenient for subsequent processing and use.

[0004] When the bead foam is placed into the mold for molding, pores will appear on the side of the molded midsole due to its own characteristics when the bead foam is melted together in a high temperature and high humidity environment. The appearance of such pores will not only damage the appearance of the finished product, but also excessive pores will lead to insufficient wear resistance of the side of the entire midsole finished product, affecting the yield of the entire finished product.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention places a film on the lower mold. Then, as the upper mold begins to descend, the positioning assembly shapes the entire film. Then, through the cooperation of the provided annular laminating plate and the exhaust pipe, air is exhausted on one side of the film after it is placed, creating an air pressure difference on one side of the film, adsorbing the film onto the entire lower mold cavity. This facilitates the subsequent introduction of high-temperature steam into the entire mold, allowing the molten bead foam to fuse with the film. The side of the finished midsole formed after the fusion is further enhanced in wear resistance due to the action of the film. 2. At the same time, when the upper mold begins to descend, the positioning card plate can cooperate with the clamping plate and the locking block. When the locking block is automatically reset by the elastic force of the third spring, it can squeeze the clamping plate, so that the clamping plate drives the positioning card plate to continue to rise for a distance, thereby storing the entire positioning card plate inside the upper mold and separating it from the lower mold, providing space for the entire bead foam to contact the film; 3. When the upper mold and the lower mold are closed together, the two semi-ring blocks in the locking assembly and the matching assembly will gradually rotate the overall angle under their own extrusion. Then, under the annular closed mouth formed by the arc-shaped clamping plate and the matching clamping plate, the rotating semi-ring blocks will automatically reset under the action of the corresponding spring pull rod. After the reset, the two semi-ring blocks will form a locked state with the arc-shaped clamping plate and the matching clamping plate, thereby reinforcing the closure formed by the upper mold and the lower mold, reducing the risk of some gas escaping to the outside through the gap between the two when high-temperature steam is introduced into the mold, thereby affecting the entire processing rate.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1 See also Figures 1 to 9, which is the first embodiment of the present invention, provides a technical solution: a bead foam midsole coating device, comprising a base 1 and a control panel 2 arranged on the base 1, the control panel 2 is used to control the entire processing process, a lower mold 3 is provided on one side of the base 1, the lower mold 3 is used to cooperate with the upper mold 6, and the two are combined together, so that when the midsole is subsequently processed, the bead foam is filled in the cavity formed by the upper mold 6 and the lower mold 3, and then high-temperature steam is sent into the cavity to soften the surface of the bead, so that the beads are melted together, and the lower mold 3 is formed. An adsorption component 4 is provided in the mold 3, and the adsorption component 4 is used to adsorb the placed film in the lower mold 3. A bracket 11 is provided on the base 1, and a hydraulic component 5 is provided on the bracket 11. 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 one end of the hydraulic component 5 and the lower mold 3 are driven to form a close and closed environment, which is convenient for the subsequent processing and softening of the bead foam. The upper mold 6 is provided near one end of the hydraulic component 5 and the lower mold 3. The upper mold 6 is used to cooperate with the lower mold 3 to form a closed chamber. The adsorption component 4 includes a square sealing plate 41 symmetrically arranged on the lower mold 3. The inner wall of the square sealing plate 41 is filled with a circle of high-temperature resistant rubber pads. The cavity between the entire mold is sealed by the fitting relationship formed with the upper mold 6, which is convenient for subsequent bead foam processing. An annular fitting plate 42 is provided inside the lower mold 3, and the surface of the annular fitting plate 42 is penetrated with air holes. The annular fitting plate 42 is consistent with the bottom cavity of the lower mold 3, and there is a certain gap between the two. When the film is placed on the lower mold 3, the air holes are set on the upper mold 6. The positioning assembly 7 positions the film for lamination and simultaneously evacuates air through the exhaust pipe 43 provided inside the lower mold 3, thereby forming an air pressure difference on both sides of the film and laminating the film in the cavity of the lower mold 3. An exhaust pipe 43 is provided throughout the lower mold 3, and the exhaust pipe 43 is interconnected with the annular laminating plate 42. An exhaust device is externally connected to the end of the exhaust pipe 43 away from the annular laminating plate 42, which is controlled by the control panel 2. When the exhaust device is activated, a certain air pressure difference is formed on the annular laminating plate 42 on one side of the cavity of the lower mold 3, and the film is adsorbed by the formed air pressure difference. When the locking plate 33 is unlocked, the locking plate 33 is locked and the locking plate 33 is unlocked, so that the locking plate 33 can be automatically reset to clamp the film placed on the surface of the lower mold 3. The locking plate 33 is movably provided on the support sleeve 32, and the locking plate 33 is rotatably connected to the support sleeve 32. Contact is formed between the locking plate 33 and the torsion spring inside the support sleeve 32. In the initial state of the torsion spring, the torsion spring is in a relaxed state. When the locking plate 33 starts to rotate, it drives the torsion spring to rotate. Under the rotation of the torsion spring, a certain elastic force is stored. When the staff releases the locking plate 33, the locking plate 33 can be automatically reset under the action of the torsion spring.

[0033] The locking plate 33 is provided with a sliding groove 34 on one side 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 to extend and retract as a whole. When the locking plate 33 starts to rotate, the telescopic rod 35 will extend a certain distance to meet the requirement 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 provided 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 support the locking plate 33 to a certain extent, so that the locking plate 33 is in a horizontal state, and the entire locking plate 33 is slightly The cam 362 is provided on the outside of the fixing rod 36 so as to prevent the film from being broken due to excessive clamping.

[0034] The locking plate 33 is symmetrically provided with a locking rod 331, and the locking guide rail 332 is symmetrically provided inside the locking groove 31, and the locking guide rail 332 and the locking rod 331 are locked and slid. A positioning component 7 is movably provided on the side of the upper mold 6 close to the lower mold 3. The positioning component 7 is used to fit and position the placed film with the inner wall of the chamber of the lower mold 3. A telescopic sleeve 61 is arranged in an array on the side of the upper mold 6 away from the lower mold 3.

[0035] First, the film is placed on the surface of the lower mold 3, and the film is positioned and clamped by the clamping plate 33 provided on the surface of the lower mold 3. After the clamping is completed, the bead foam particles to be processed are filled into the cavity of the lower mold 3. At this time, the film will slide toward 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 started through the control panel 2, so that the hydraulic component 5 drives the upper mold 6 to start descending. During the descending process of the upper mold 6, the positioning component 7 provided will shape the entire film so that the overall shape of the film is consistent with the original shape. The cavity shape of the lower mold 3 is consistent. 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 provided on the lower mold 3 and the matching component 10 provided on the upper mold 6. Then the vacuum device connected to the vacuum pipe 43 can be started to generate an air pressure difference on one side of the film, so that the film is adsorbed in the cavity shape of the lower mold 3. Then the vacuum device can be closed and the external high-temperature steam delivery device can be turned on. The high-temperature steam is delivered to the cavity between the upper mold 6 and the lower mold 3 through the delivery pipe provided on the upper mold 6 to process the placed bead foam so that it eventually becomes the finished midsole.

[0036] Example 2 See also Figures 1 to 10 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: The positioning assembly 7 includes a movable ring 71 movably arranged on the upper mold 6, and a throat-shaped groove is opened inside the movable ring 71. The movable ring 71 is rotatably connected to the upper mold 6 so that the movable ring 71 can rotate freely. A sliding sleeve rod 72 is movably arranged inside the movable ring 71, and the sliding sleeve rod 72 is composed of a straight rod and a spiral rod. When the upper mold 6 begins to descend, the positioning card plate 73 set at one end of the sliding sleeve rod 72 begins to contact the film laid on the surface of the lower mold 3. The positioning card plate 73 can press the film downward to make the film enter the cavity of the lower mold 3. When the film enters the cavity of the lower mold 3, the air pressure on one side of the film is changed by starting the external exhaust device, so that the film is adsorbed on the cavity of the lower mold 3 and slides. The locking cam 73 is pressed against the locking cam 74 so that the locking cam 74 can be locked together with the support cam 74 when the locking cam 74 is in a locked position.

[0037] The upper array of 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 upper array of the lower mold 3 is provided with a locking component 9. The upper array of the upper mold 6 is provided with a matching component 10, and the matching component 10 and the locking component 9 form a match to lock the upper mold 6 and the lower mold 3.

[0038] The clamping assembly 8 includes a clamping seat 81 arranged in an array in the upper mold 6, and the clamping seat 81 and the corresponding clamping plate 74 are in the same vertical line. One side of the clamping seat 81 has an open slot for facilitating the entry of the clamping plate 74, through which the clamping plate 74 can smoothly enter the interior when it approaches the clamping seat 81 without being blocked. A partition plate 82 is provided inside the clamping seat 81, and the partition plate 82 is used to support the square pipe 821 provided inside the clamping seat 81. A support plate 83 is provided inside the clamping seat 81. The support plate 83 is a combination of a U-shaped plate and a straight column, and the straight column has a cavity inside. A sliding clamping rod 84 is symmetrically provided on the support plate 83. The movable clamping rod 84 is provided with a slot on its surface, through which it engages and slides with the support plate 83, so that when the sliding clamping rod 84 is displaced, the sliding clamping rod 84 as a whole will not rotate, which will affect the locking block 85 provided at one end of the sliding clamping rod 84. The two sliding clamping rods 84 are provided with a locking block 85 at the opposite end, and the locking block 85 is used to cooperate with the clamping plate 74. When the clamping plate 74 enters the slot of the engaging seat 81 and contacts the locking block 85, when the clamping plate 74 moves to a predetermined position, the provided locking block 85 can be reset under the action of the third spring 86, so that the clamping plate 74 continues to rise a certain distance and is stored inside the upper mold 6.

[0039] The outer sleeve of the sliding card rod 84 is provided with a third spring 86, which is used to provide 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 squeeze the clamping plate 74, so that the clamping plate 74 moves a certain distance and is stored in the upper mold 6. The partition plate 82 is provided with a square pipe 821 on the side close to the support plate 83, and the square pipe 821 is fixedly connected to the support plate 83 on the side away from the partition plate 82. The square pipe 821 is used to form a communication with the cavity section of the straight column on the support plate 83. A fixed limit rod 831 is provided inside the support plate 83, and the fixed limit rod 831 is located inside the straight column section of the support plate 83. The fixed limit rod 831 is inside the straight column section of the support plate 83, separating the notches inside the straight column section, so that when moving into the mold. When the high-temperature steam is filled in the upper part, the residual moisture in the steam will not enter the other side of the straight column section of the support plate 83. The entire fixed limit rod 831 is made of copper material with high thermal conductivity to transfer the temperature of the high-temperature steam. A conveying straight rod 832 is provided inside the support plate 83, and a cavity is provided inside the conveying straight rod 832 to fit and slide 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 provided in the 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 elasticity, and when the helium is heated, the overall volume will expand, thereby pushing the conveying straight rod 832 to move.

[0040] A fixed plate 833 is provided at one end of the conveying straight rod 832 away from the support plate 83, and a limiting guide rail 834 is symmetrically provided on the fixing plate 833, and the limiting guide rail 834 is engaged and slid with the corresponding locking block 85. The limiting guide rail 834 is obtuse-angled, and is used to drive the corresponding locking block 85 to open to both sides after the conveying straight rod 832 starts to move. At the same time, after opening to a certain position, the continued movement of the conveying straight rod 832 will cause the locking block 85 to be limited at the current position and no longer move.

[0041] When the locking block 85 is pushed open, the locking plate 74 will come into contact with the inclined surface of the locking block 85, and the locking block 85 will be reset under the elastic force of the third spring 86. The reset locking block 85 will continue to drive the clamping plate 74 to rise. Finally, after the entire positioning clamping plate 73 is moved to the specified position, the positioning clamping plate 73 can continue to move upward for a distance under the action of the two to store the entire positioning clamping plate 73 inside the upper mold 6, avoiding the positioning clamping plate 73 from affecting it during the processing of the bead foam.

[0042] The remaining structures are the same as those of Example 1.

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 is separated from the lower mold 3. When the plug-in plate 97 is F-shaped and close to the square card groove 961 on the fixed lock plate 96, the square card groove 961 is first leveled, and then the support plate on the upper part of the plug-in plate 97 is inserted into the inside of the square card groove 961, so that the semi-ring block 93 is rotated and its straight surface is parallel to the arc-shaped card plate 92. At this moment, the upper mold 6 and the lower mold 3 can begin to separate.

[0044] The mating component 10 includes a mating bin 101 arranged in an array on the upper mold 6, a mating card plate 102 is arranged inside the mating bin 101, and the overall shape of the mating card plate 102 is consistent with the arc-shaped card plate 92, and a mating part 103 is movably arranged on the side of the mating bin 101 close to the mating card plate 102. The mating part 103 is composed of the same semi-ring block 93, the locking push plate 94 and the spring pull rod 95, so that the two same semi-ring blocks 93 will form a circular annular groove formed by the mating card plate 102 and the arc-shaped card plate 92 after being fitted together, and the engagement and locking are formed under the action of the two spring pull rods 95.

[0045] When the upper mold 6 descends and contacts the lower mold 3, the arc-shaped clamping plate 92 provided on the lower mold 3 and the matching clamping plate 102 on the upper mold 6 will contact the two first and gradually splice into an annular groove, and the two semi-ring clamping blocks 93 respectively provided on the upper mold 6 and the lower mold 3 begin to rotate under mutual extrusion. When the two semi-ring clamping blocks 93 are spliced ​​into a circle, the two rotating semi-ring clamping blocks 93 will be reset under the action of the corresponding two spring pull rods 95. The reset two semi-ring clamping blocks 93 will form a locking state with the spliced ​​arc-shaped clamping plate 92 and the matching clamping plate 102, thereby reinforcing and stabilizing the fit between the upper mold 6 and the lower mold 3. At the same time, the springs used above are made of high-temperature resistant materials to avoid the high-temperature environment affecting the service life of the springs.

[0046] The remaining structures are the same as those of Examples 1 and 2.
