Description

Technical Field

[0001] The invention relates to the technical field of sole manufacturing, and in particular to a highly transparent EPDM rubber sole and a manufacturing method thereof. Background Art

[0002] Traditional transparent rubber soles mainly use cis-1,4-dibutyl rubber and solution-polymerized styrene-butadiene rubber as the main rubber materials. However, the two rubber macromolecular chains have a high content of unsaturated double bonds, which results in poor weather resistance of the rubber soles made from them. They are prone to yellowing, cracking, aging and other problems, which in turn affect the quality of the shoes.

[0003] The invention patent with patent application publication number CN 107603033 B discloses a shoe material, in particular, a highly transparent EPDM rubber sole and a method for making the same. It is made from the following raw material formula: (1) the first formula: composed of a main rubber and an auxiliary agent, wherein the main rubber is composed of EPDM and MPU; (2) the second formula: the first formula rubber and a cross-linking agent. The first formula is first mixed, kneaded and rolled into a first raw material sheet through an open mill, and the first raw material sheet is placed to stand and then put into an open mill, and a cross-linking agent is added according to the second formula to mix and refine into a rubber sheet, which is then placed to stand, punched and vulcanized.

[0004] However, after being put into actual application by technicians skilled in the art, it was found that the above production method still has some shortcomings. The most obvious one is that after the rubber sheet is punched out and placed in the mold for vulcanization, due to the high mold temperature and long vulcanization time, the operator will have a long rest period during the vulcanization period, which has a great impact on the production efficiency of the sole. At the same time, when the molded sole is subsequently taken out of the mold and a new rubber sheet is placed, the technicians will face great operating difficulties due to the influence of the mold temperature.

[0005] In addition, when demolding the molded sole, since it is usually attached to the surface of the lower mold, the technician needs to push it manually to create a gap between it and the lower mold so that it can be removed more conveniently. This will also increase the contact time between the technician and the lower mold, further increasing the impact of the lower mold temperature on the technician.

[0006] Therefore, it is necessary to invent a highly transparent EPDM rubber sole and a manufacturing method thereof to solve the above problems. Summary of the invention

[0007] The object of the present invention is to provide a highly transparent EPDM rubber sole and a manufacturing method thereof, so as to solve the problems raised in the above background technology.

[0020] Preferably, the method for making the highly transparent EPDM rubber sole specifically comprises the following steps:

[0021] S1. A high-transparency EPDM rubber sheet is prepared with the raw materials in the first formulation and the second formulation, and the high-transparency EPDM rubber sheet is punched out. The punched out high-transparency EPDM rubber sheet is placed inside the two die grooves on the left lower die base at the operating station, and then it is pushed backward to slide along the guide rail to the heating and pressurizing station under the upper die plate. Then, the hydraulic cylinder drives the upper die plate to descend through the lifting plate, and then drives the upper die plate to cover the top of the lower die base and heat it. The heating component inside the upper die plate heats the rubber sheet, and then starts to vulcanize the rubber sheet;

[0022] S2. During this process, the rubber sheet is taken again and placed inside the two mold grooves on the right lower mold base. After the left rubber sheet is vulcanized, the hydraulic cylinder drives the upper mold plate to reset through the lifting plate, and then the left handle is pulled and the right handle is pushed at the same time, so that the left lower mold base is moved out from the bottom of the left upper mold plate, and the right lower mold base enters the bottom of the right upper mold plate;

[0023] S3. When pulling the left handle, the handle drives the left panel to move to the cooling station, that is, the panel fits against the back of the mounting base. During the fitting process, the left panel pushes the left rack, and the left rack contracts into the cavity. During the contraction process, the rotation shaft is driven to rotate by the gear. When the rotation shaft rotates, the L-shaped pressing rod is driven to rotate by the rotating block, so that the two L-shaped pressing rods respectively press against the tops of the two vulcanized rubber sheets;

[0024] S4. The air inlet pipe inputs air flow into the cavity, and the air flow is output after passing through the valve flap. When the rack is pushed by the panel into the cavity, the rack drives the closing cover plate to move away from the end of the second connecting pipe. At this time, due to the resistance of the valve flap, the air flow in the cavity enters the first connecting pipe through the second connecting pipe, then passes through the inside of the lower die base, and is then ejected from multiple air holes, so as to dissipate heat from the lower die base and blow the vulcanized rubber sheet at the same time, so as to make it demold and turn over. During this process, the L-shaped pressing rod presses any place on the vulcanized rubber sheet to prevent the rubber sheet from flying;

[0025] S5. Then push the handle backward to the operating position. At this time, the torsion spring drives the L-shaped pressing rod to reset, so as to release the pressing on the rubber sheet. At the same time, the gear drives the rack to reset, so that the closing cover plate closes the second connecting pipe again. Then take off the rubber sheet that has been cooled and no longer fits against the lower die base from the top of the cooled lower die base, and then take the rubber sheet again and repeat the above operations;

[0026] S6. Trim the burrs of the cooled rubber sheet to obtain a highly transparent ethylene propylene diene monomer (EPDM) rubber sole.

[0027] The technical effects and advantages of the present invention:

[0028] By providing a lower molding component, an air-cooling mechanism, a trigger locking mechanism and an air-cooling transmission mechanism, the present invention facilitates the demolding and feeding of the right lower molding component during the vulcanization process of the left lower molding component. At the same time, when the lower molding component moves from the heating and pressurizing station to the cooling station, it can trigger the trigger locking mechanism, so that the trigger locking mechanism releases the restriction on the air-cooling transmission mechanism, so that the air-cooling mechanism cools the lower molding component through the air-cooling transmission mechanism, cools the vulcanized rubber sheet and turns it over. In addition, the trigger locking mechanism can also lock the vulcanized rubber sheet to prevent the rubber sheet from flying during the cooling process. Compared with the same type of preparation method in the prior art, the present invention can effectively shorten the operation rest period, improve the preparation efficiency, cool the lower molding component, cool the vulcanized rubber sheet and turn it over, so as to reduce the operation difficulty during the demolding of the rubber sheet and improve the demolding efficiency of the rubber sheet.

[0048] Embodiment 2

[0049] The manufacturing method of the highly transparent ethylene propylene diene monomer rubber sole specifically includes the following steps:

[0050] S1. A high-transparency EPDM rubber sheet is prepared with the raw materials in the first formulation and the second formulation, and the high-transparency EPDM rubber sheet is punched out. The punched out high-transparency EPDM rubber sheet is placed inside the two die grooves 33 on the left lower die base 31 at the operating station, and then it is pushed backward to slide along the guide rail 32 to the heating and pressurizing station below the upper die plate 24. Then, the hydraulic cylinder 22 drives the upper die plate 24 to descend through the lifting plate 23, and then drives the upper die plate 24 to cover the top of the lower die base 31 and heat it. The heating component inside the upper die plate 24 heats the rubber sheet, and then starts to vulcanize the rubber sheet;

[0051] S2. During this process, the rubber sheet is taken again and placed inside the two mold grooves 33 on the right lower mold base 31. After the left rubber sheet is vulcanized, the hydraulic cylinder 22 drives the upper mold plate 24 to reset through the lifting plate 23. Then, the left handle 39 is pulled and the right handle 39 is pushed, so that the left lower mold base 31 is moved out from the bottom of the left upper mold plate 24, and the right lower mold base 31 enters the bottom of the right upper mold plate 24.

[0052] S3, when the left handle 39 is pulled, the handle 39 drives the left panel 37 to move to the cooling station, that is, the panel 37 is fitted with the back of the mounting seat 41. During the fitting process, the left panel 37 pushes the left rack 51, and the left rack 51 shrinks into the cavity 42. During the shrinking process, the rotating shaft 52 is driven to rotate by the gear 53. When the rotating shaft 52 rotates, the rotating block 55 drives the L-shaped clamping rod 56 to rotate, so that the two L-shaped clamping rods 56 are respectively pressed on the top of the two vulcanized rubber sheets;

[0053] S4, the air inlet pipe 43 inputs air into the cavity 42, and the air is output after passing through the valve 44. When the rack 51 is pushed into the cavity 42 by the panel 37, the rack 51 drives the closing cover plate 61 to move away from the end of the second connecting pipe 62. At this time, due to the resistance of the valve 44, the air in the cavity 42 passes through the second connecting pipe 62 into the first connecting pipe 38, and then passes through the lower mold base 31, and then sprays out from the multiple air holes 35, thereby dissipating heat from the lower mold base 31, and at the same time, the vulcanized rubber sheet is blown, thereby demolding and rolling. In this process, the L-shaped pressing rod 56 presses any point on the vulcanized rubber sheet to prevent the rubber sheet from flying;

[0054] S5. Subsequently, push the handle 39 backward to the operating position. At this time, the torsion spring 54 drives the L-shaped pressing rod 56 to reset, thereby releasing the pressing on the rubber sheet. At the same time, the gear 53 drives the rack 51 to reset, so that the closing cover plate 61 closes the second communication pipe 62 again. Then, take the rubber sheet that has cooled down and no longer adheres to the lower mold base 31 from the top of the cooled lower mold base 31. Then, take the rubber sheet again and repeat the above operations;

[0055] S6. Trim the burrs of the cooled rubber sheet to obtain a highly transparent ethylene propylene diene monomer (EPDM) rubber sole.

[0056] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

S3. When pulling the left handle (39), the handle (39) drives the left panel (37) to move to the cooling station, that is, the panel (37) is attached to the back of the mounting seat (41). During the attachment process, the left panel (37) pushes the left rack (51), and the left rack (51) contracts into the cavity (42). During the contraction process, the rotation shaft (52) is driven to rotate by the gear (53). When the rotation shaft (52) rotates, the L-shaped pressing rod (56) is driven to rotate by the rotating block (55), so that the two L-shaped pressing rods (56) are respectively pressed on the tops of the two vulcanized rubber sheets; S4. The air inlet pipe (43) inputs air flow into the cavity (42), and the air flow is output after passing through the valve membrane (44). When the rack (51) is pushed by the panel (37) into the cavity (42), the rack (51) drives the closing cover plate (61) to move away from the end of the second connecting pipe (62). At this time, due to the resistance of the valve membrane (44), the air flow inside the cavity (42) enters the first connecting pipe (38) through the second connecting pipe (62), then passes through the inside of the lower die base (31), and is ejected from a plurality of air holes (35), thereby dissipating heat from the lower die base (31) and blowing the vulcanized rubber sheet at the same time, so that it is demolded and turned over. Herein, the L-shaped pressing rod (56) presses any place on the vulcanized rubber sheet to prevent the rubber sheet from flying; S5. Then push the handle (39) backward to the operating position. At this time, the torsion spring (54) drives the L-shaped pressing rod (56) to reset, thereby releasing the pressing on the rubber sheet. At the same time, the gear (53) drives the rack (51) to reset, so that the closing cover plate (61) closes the second connecting pipe (62) again. Then take the rubber sheet that has been cooled and no longer attached to the lower die base (31) from the top of the cooled lower die base (31), then take the rubber sheet again, and repeat the above operations; S6. Trim the edges of the cooled rubber sheet to obtain a highly transparent ethylene propylene diene monomer (EPDM) rubber sole.
