Description

Technical Field

[0001] This invention belongs to the field of shoe sole hydraulic technology, specifically a quick mold changing device and mold changing method for a shoe sole hydraulic press. Background Technology

[0002] The shoe sole hydraulic press mold is a special tooling installed on a hydraulic molding machine. It consists of an upper mold, a lower mold, and a guide and positioning mechanism. During production, shoe sole raw materials such as rubber and EVA are placed into the mold cavity. The hydraulic press applies high pressure and heats the mold, causing the raw materials to vulcanize or foam and form in the mold cavity. The final product is a shoe sole product with anti-slip texture, trademark, and precise contour. It is the core tool for achieving mass production of shoe soles.

[0003] In existing technologies, this mold typically consists of an upper mold, a lower mold, a guide positioning mechanism composed of guide pillars and guide sleeves, a mold cavity, and heating holes. After the upper and lower molds are closed, a closed cavity is formed. After the shoe sole material is placed in, a hydraulic press provides high pressure to lock the mold and heat it, so that the material is vulcanized or foamed and shaped in the mold cavity, ultimately producing shoe sole products with anti-slip textures, trademarks, and precise contours. It is the basic tooling for achieving mass production.

[0004] Existing shoe sole hydraulic press molds typically have upper and lower mold cavities integrally formed with the mold body. Therefore, if a change in sole pattern or size is needed during production, the entire mold must be replaced. Furthermore, when a part of the mold cavity is damaged, it is often difficult to repair individually, requiring the entire mold set to be scrapped. This results in poor equipment versatility and high maintenance costs. Therefore, this paper proposes a quick-change mold device and method for shoe sole hydraulic presses to address these issues. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, the present invention proposes a quick mold changing device and mold changing method for a shoe sole hydraulic press.

[0006] The technical solution adopted by this invention to solve its technical problem is: a mold changing method for a shoe sole hydraulic press, comprising the following steps: S1: The mold body is pre-assembled on the disassembly platform and double locking is achieved by the locking component; the limiting slide rail is inserted from the side of the shoe sole mold, and the mold body is pushed into the assembly position so that the fixed inner cylinders at both ends of the mold body are aligned with the fixed block at the front end of the threaded column; the rotating connecting operation plate drives the transmission gear and bevel gear cylinder to move the threaded column up and down along the limiting column, so that the fixed block is inserted into the fixed inner cylinder to complete the main locking; the pressing down connecting rod drives the connecting slider to move down, and the insert rod clamps the limiting insert plate on the mold body to complete the auxiliary locking. The mold body can be disassembled and assembled separately by relying on the locking component, without replacing the entire shoe sole mold; S2: Mold closing and transfer vulcanization. After pre-assembly, the two sets of shoe sole molds are closed with the help of the connecting shaft and connecting seat. Hold the connecting handle and move the entire tooling from the fixed base of the disassembly platform to the hydraulic press. The equipment pressurizes in conjunction with the mold heating structure to vulcanize and foam the rubber and EVA raw materials in the mold body. After processing, the entire tooling is transported back to the top of the disassembly platform and placed there. S3: Mold opening, unloading, and mold changing. Push the closed sole mold between the two fixed side seats. During movement, the guide plate and the rotating column guide limit. The transmission rack and connecting gear plate mesh to lift the upper sole mold. The support platform on the limit track is equipped with a protective soft plate to support the fixed base and prevent collisions.

[0020] 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.

[0021] Specific implementation examples are given below.

[0022] Please see Figure 1 This invention provides a mold changing method for a shoe sole hydraulic press, comprising the following steps: S1: The mold body 2 is pre-assembled on the disassembly platform 1 and double locking is achieved by the locking component; the limiting slide rail 21 is inserted from the side of the shoe sole mold 12 and the mold body 2 is pushed into the assembly position so that the two ends of the mold body 2 are aligned with the front end of the threaded column 27 and the fixing block 28; the connecting operation plate 22 is rotated to drive the transmission gear 210 and the bevel gear cylinder 29 to move the threaded column 27 up and down along the limiting column 26, so that the fixing block 28 is inserted into the fixing inner cylinder 23 to complete the main locking; the connecting rod 32 is pressed down to drive the connecting slider 31 to move down, and the insertion rod 33 clamps the limiting insertion plate 3 on the mold body 2 to complete the auxiliary locking. The mold body 2 is disassembled and assembled separately by relying on the locking component, without replacing the entire shoe sole mold 12; S2: Mold closing, transfer and vulcanization. After pre-assembly, the two sets of shoe sole molds 12 are closed with the help of the connecting shaft 13 and the connecting rotating seat 14. Hold the connecting handle 15 and move the entire tooling from the fixed base 11 of the disassembly platform 1 to the hydraulic press. The equipment pressurizes in conjunction with the mold heating structure to vulcanize and foam the rubber and EVA raw materials in the mold body 2. After processing, the entire tooling is transported back to the top of the disassembly platform 1 and placed there. S3: Mold opening, unloading, and mold changing. Push the closed sole mold 12 between the two fixed side seats 41. When moving, the guide plate 5 and the fitting rotating column 51 guide and limit the movement. The transmission rack 42 and the connecting gear plate 4 mesh to lift the upper sole mold 12. The support platform 61 on the limit track 6 is equipped with a protective soft plate 9 to support the fixed base 11 to prevent collisions. Insert the pry bar into the pry groove 16 to separate the mold and remove the finished sole. If it is necessary to replace the mold body 2, rotate the connecting operation plate 22 in the opposite direction on the disassembly platform 1 to release the main lock, lift the connecting rod 32 and retract the insertion rod 33 to release the auxiliary lock, insert the pry bar into the slot 71 of the demolding rod 7, and pull out the mold body 2 along the limit slide rail 21. Repeat S1 to assemble the new mold body 2.

[0023] A quick-change device for a shoe sole hydraulic press includes a disassembly platform 1. A pair of fixed bases 11 are slidably provided on the top of the disassembly platform 1. A shoe sole mold 12 is fixedly connected to one end of each pair of fixed bases 11. Multiple sets of connecting shafts 13 are fixedly connected to one side of the bottom shoe sole mold 12, and multiple sets of connecting pivots 14 are fixedly connected to one side of the top shoe sole mold 12. The multiple sets of connecting pivots 14 are hinged to the multiple sets of connecting shafts 13. A connecting handle 15 is fixedly connected to the side wall of each pair of shoe sole molds near the disassembly platform 1. A pry groove 16 is opened on the side of each pair of shoe sole molds near the connecting handle 15. The two pry grooves 16 are interconnected. A locking component is provided inside each pair of fixed bases 11 for quick replacement of the mold cavity. The locking assembly includes a pair of mold bodies 2, which are disposed between a pair of shoe sole molds 12. Each pair of shoe sole molds 12 has a slidably connected limit rail 21 on its inner side. The sidewalls of the limit rails 21 that are close to each other are connected to the sidewalls of the mold bodies 2. Each pair of mold bodies 2 has a fixed inner cylinder 23 at one end away from each other. Each pair of fixed bases 11 has a storage slot 24 on one side near the connecting handle 15. A fixed seat 25 is fixedly connected to one end of each storage slot 24 at one end away from each other. The fixed seats 25 are close to each other. Each of the two storage slots 24 has a limiting post 26 fixedly connected to one end. Each pair of limiting posts 26 has a threaded post 27 slidably connected to the outer side of each pair of limiting posts 26. Each pair of threaded posts 27 has a fixing block 28 fixedly connected to one end close to each other. Each pair of storage slots 24 has a bevel gear cylinder 29 rotatably connected to one end close to each other. Each pair of bevel gear cylinders 29 is threadedly connected to one pair of threaded posts 27. Each pair of storage slots 24 has a transmission gear 210 rotatably connected to one end far from each other. The transmission gear 210 meshes with the bevel gear cylinder 29. Each pair of transmission gears 210 has a connecting operation plate 22 fixedly connected to the outer wall of the outer side of the outer side of the outer side. During operation, when the mold body 2 needs to be replaced, the limiting slide rail 21 serves as the sliding installation channel for the mold body 2. The limiting slide rail 21 is inserted from the side wall of the sole mold 12, and the mold body 2 is pushed into the inner side of the sole mold 12. At this time, the fixed inner cylinder 23 and the fixed locking block 28 are on the same vertical line. The operator can directly rotate the connecting operating plate 22, which drives the transmission gear 210 to rotate. During the rotation of the transmission gear 210, the bevel gear cylinder 29 meshes with the transmission gear 210, and the limiting post 26... The movement range of the threaded column 27 and the fixed block 28 is limited. During the rotation of the bevel gear cylinder 29, the threaded column 27 and the fixed block 28 can be directly pushed up and down, eventually allowing the fixed block 28 to insert into the inner side of the fixed inner cylinder 23, thus completing the main locking operation of the mold body 2. When it is necessary to replace the mold body 2 installed inside the shoe sole mold 12, the connecting operating plate 22 can be rotated in the opposite direction to disengage the fixed block 28 from the inner side of the fixed inner cylinder 23. The entire mechanical linkage structure does not require the replacement of the entire shoe body. The bottom mold 12 allows for convenient and rapid replacement of the mold chamber. After replacement, rubber or EVA material shoe sole raw materials can be placed in the inner cavity of the mold body 2. By connecting the rotating shaft 13 and the connecting rotating seat 14, the pair of shoe sole molds 12 can be closed together, allowing the entire equipment to be moved into the hydraulic press. The hydraulic press, combined with the mold heating structure, completes the hydraulic vulcanization molding process. After vulcanization, the entire equipment can be removed and placed on top of the disassembly platform 1. The pry bar can be used to pry open the pry groove 16 to carry out subsequent mold unloading. The entire device, with its locking components and a separate structure design for the mold body and shoe sole mold, effectively improves the problem of having to replace the entire mold when changing shoe sole patterns or sizes using traditional equipment. It also reduces the need to scrap the entire mold after partial damage to the mold cavity, significantly reducing the material costs associated with mold procurement and scrapping. The entire device effectively enhances the equipment's universal adaptability to different styles and sizes of shoe soles, while simultaneously reducing the daily maintenance costs of the equipment.

[0024] Furthermore, such as Figure 6 and Figure 8As shown, a pair of limiting plates 3 are fixedly connected to one side wall of each pair of mold bodies 2. A pair of connecting sliders 31 are slidably connected to the side of each pair of shoe sole molds 12 near the limiting plates 3. A connecting rod 32 is fixedly connected to the side wall of each pair of connecting sliders 31. An insert rod 33 is fixedly connected to the end of each pair of connecting sliders 31 away from the connecting rod 32. The bottom end of the insert rod 33 is set with an inclined curved surface. During operation, when the mold body 2 is inserted into the shoe sole mold 12 through the limiting slide rail 21, the limiting plates 3 can squeeze the curved surface of the insert rod 33, thereby making the insert rod 33 The connecting slider 31 and connecting rod 32 are moved upwards. When the limiting plate 3 moves to the installation area, the operator can operate the connecting rod 32 and drive a pair of insert rods 33 to be inserted into the inner side of the limiting plate 3 through the connecting slider 31, thus completing the auxiliary locking work of the mold body 2. The overall device, with its main and auxiliary double locking structure, distributes the molding force, effectively reducing the stress load at the connection between the fixed inner cylinder 23 and the fixed block 28. This significantly improves the operational stability of the equipment under long-term continuous high-pressure operation and reduces the risk of mold displacement, component deformation and breakage.

[0025] Furthermore, such as Figure 3 and Figure 4 As shown, the top shoe sole mold 12 is rotatably connected to connecting gear discs 4 on both sides near the connecting rotating seat 14. The top of the disassembly platform 1 is fixedly connected to a pair of fixed side seats 41, and the pair of fixed side seats 41 are fixedly connected to a transmission rack 42 on one side close to each other. During operation, when it is necessary to separate the pair of shoe sole molds 12 after vulcanization, the shoe sole mold 12 can be directly pushed into the inside of the pair of fixed side seats 41, and the pair of transmission racks 42 can drive the pair of connecting gear discs 4 to rotate upward, so that the top shoe sole mold 12 and the bottom shoe sole mold 12 are separated from each other, and the disassembly and unloading operation of the pair of shoe sole molds 12 is automatically completed, simplifying the manual mold opening steps, effectively shortening the unloading time, and improving the operating efficiency of the equipment for long-term continuous production.

[0026] Furthermore, such as Figure 2 As shown, each of the pair of fixed side seats 41 has a guide curved plate 5 fixedly connected to one end near the fixed base 11. Each of the side walls of the pair of guide curved plates 5 is rotatably connected to a pair of fitting rotating columns 51. During operation, before the shoe sole mold 12 is sent into the inner side of the pair of fixed side seats 41, the pair of guide curved plates 5 and the fitting rotating columns 51 cooperate with each other to guide and limit the shoe sole mold 12, simplifying the operation difficulty of disassembling the mold by relying on the connecting gear plate 4 and the transmission rack 42, and improving the stability of the disassembly process. The fitting rotating columns 51 can rotate synchronously with the mold movement, replacing sliding friction with rolling friction, effectively reducing the frictional loss between the guide curved plates 5 and the contact surfaces of the fixed base 11 and the shoe sole mold 12, and extending the service life of the parts.

[0027] Furthermore, such as Figure 4As shown, a limiting rail 6 is fixedly connected to one side of the bottom fixed base 11, and a support platform 61 is slidably fitted inside the limiting rail 6. During operation, when the transmission rack 42 drives the top shoe sole mold 12 to rotate upward through the connecting gear plate 4, the support platform 61 can provide stable support for the top fixed base 11. Workers can directly collect the shoe sole products that have been formed in the cavity of a pair of mold bodies 2. At the same time, it can prevent the top fixed base 11 from colliding with external components and reduce the probability of tooling damage.

[0028] Furthermore, such as Figure 4 As shown, each of the two mold bodies 2 has a demolding rod 7 fixedly connected to the side wall away from the limiting plate 3. Each of the two demolding rods 7 has a slot 71 at one end away from each other. During operation, the demolding rod 7 and the slot 71 cooperate with each other. The operator can directly insert an external pry bar into the inside of the slot 71 and use external force to pull the mold body 2 out smoothly along the limiting slide rail 21. This eliminates the need for violent knocking and disassembly, improves the stability of the process of removing the mold body 2 from the inside of the shoe sole mold 12, and avoids damage to the mold cavity from impacts.

[0029] Furthermore, such as Figure 2 As shown, each of the pair of fitting rotating columns 51 is fixedly connected to a support auxiliary seat 8 on a side away from each other. The bottom of the pair of support auxiliary seats 8 is connected to the top of the disassembly platform 1. During operation, the support auxiliary seat 8 can provide stable support to the end of the guide curved plate 5, strengthen the overall support strength of the guide curved plate 5, distribute the stress burden at the connection position between the guide curved plate 5 and the fixed side seat 41, and prevent the guide structure from being deformed by long-term stress.

[0030] Furthermore, such as Figure 4 As shown, a protective soft plate 9 is fixed to the top of the support platform 61. During operation, the protective soft plate 9 can replace the top surface of the support platform 61 to directly contact the top fixed base 11, buffering the impact generated by the contact between the two, improving the stability of the support of the fixed base 11, and reducing the wear and tear caused by long-term friction and impact on the surface of the support platform 61, thus reducing the frequency of parts replacement.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
