Description

Technical Field

[0001] This utility model relates to the field of shoe sole molding mold technology, specifically to a three-dimensional molding mold for multi-color shoe soles. Background Technology

[0002] In the footwear industry, sole molding dies are the core equipment for shaping soles and enabling mass production, and their importance is self-evident. Given the variety of sole types and specifications, in order to create soles with multiple colors and three-dimensional shapes, it is often necessary to make targeted improvements to the core and cavity of the mold.

[0003] However, in current common shoe sole manufacturing processes, most molding dies use a hinged connection between the upper and lower molds via a rotatable assembly. During production, the rubber compound is first placed in the mold cavity, and then the sole is formed by the pressing action of the upper and lower molds. After the sole is formed, operators need to manually remove it using tools such as picks. This process has significant drawbacks: the removal process is time-consuming, and in large-scale shoe sole production, it's impossible to simultaneously remove already formed soles while a new batch is being produced, greatly impacting mold efficiency and thus limiting production efficiency. Utility Model Content

[0004] In view of the problems existing in the three-dimensional molding molds for multi-color molded shoe soles, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a three-dimensional molding mold for multi-color molded shoe soles, which solves the problem that it is impossible to simultaneously remove the molded shoe soles while a new batch of shoe soles is being molded during large-scale shoe sole production.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A three-dimensional molding mold for multi-color molded shoe soles includes an upper mold and a lower mold. The bottom of the upper mold is provided with a molding chamber. The interior of the lower mold has a through hole and two symmetrically arranged molding modules. A rotating plate is fixed between the two molding modules. A crossbar is fixed at both ends of the rotating plate. The ends of the two crossbars that are far apart are rotatably disposed on the inner sidewall of the through hole. The end of one crossbar protrudes from the through hole and is provided with a rotation positioning mechanism for limiting the position of the molding module.

[0008] The bottom of the lower mold is fixedly provided with a feeding ring, which is connected to the through hole.

[0009] Preferably, the rotation positioning mechanism includes a rotating block, which is fixedly connected to a crossbar. The outer wall of the lower mold has a rotation groove, and the rotating block is located in the rotation groove. Both sides of the rotating block have pressing grooves. The inner wall of the pressing groove is fixedly provided with a spring, and a positioning rod is fixedly provided through the spring. The inner wall of the rotation groove has multiple positioning grooves arranged symmetrically around the perimeter, and the end of the positioning rod is inserted into the positioning groove.

[0010] Preferably, the positioning rod is an L-shaped rod, with its end extending out of the rotating groove and reaching the outside.

[0011] Preferably, the inner wall of the feeding ring is fixedly provided with an annular tube, and the tube wall of the annular tube is connected to a plurality of air outlets arranged symmetrically in a ring. The air outlets are inclined. An air guide hood is fixedly provided through the side of the feeding ring. The air outlet of the air guide hood extends out of the side of the feeding ring and is connected to the annular tube. An air inlet fan is fixedly provided on the outer wall of the air guide hood.

[0012] Furthermore, sliding grooves are provided on both sides of the inner wall of the pressing groove, and a sliding plate is slidably inserted through the interior of two adjacent sliding grooves. The sliding plate is fixedly inserted inside the positioning rod.

[0013] Preferably, the openings of the plurality of air outlet pipes are all oriented toward the molding module.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This invention, by setting two symmetrical molding modules, allows for the removal of a shoe sole already formed on the other molding module while one module is molding the sole. This achieves simultaneous molding and removal, significantly reducing the overall removal time, improving mold utilization efficiency, and ultimately increasing the efficiency of large-scale shoe sole production.

[0016] This invention, by rotating the positioning rod in the positioning mechanism and cooperating with the positioning groove, can precisely limit the position of the molding module, ensuring that the molding module is accurately positioned each time the upper and lower molds are closed, thus ensuring the molding accuracy of the shoe sole.

[0017] This invention, through the setting of a feeding ring, annular pipe, air outlet pipe, air guide hood and air intake fan, allows air to enter the annular pipe through the air guide hood when the air intake fan is working, and then be blown out from the air outlet pipe. The air outlet pipe, which is set at an angle and faces the molding module, can generate airflow to help the molded shoe soles fall off the molding module, further improving the part removal efficiency.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a three-dimensional molding mold for multi-color molded shoe soles.

[0026] This utility model provides, for example Figure 1-3 A three-dimensional molding mold for multi-color molded shoe soles includes an upper mold 1 and a lower mold 2. The bottom of the upper mold 1 is provided with a molding chamber 3. The interior of the lower mold 2 has a through hole and two symmetrically arranged molding modules 4. A rotating plate 5 is fixed between the two molding modules 4. A crossbar 6 is fixed at both ends of the rotating plate 5. The two crossbars 6 are rotatably mounted on the inner wall of the through hole at one end away from each other. The end of one crossbar 6 passes through the through hole and is provided with a rotation positioning mechanism for limiting the position of the molding module 4. The rotation positioning mechanism includes a rotating block 8, which is fixedly connected to the crossbar 6. A rotating groove is provided on the outer wall of the lower mold 2. The rotating block 8 is located in the rotating groove. Pressing grooves are provided on both sides of the rotating block 8. A spring 9 is fixedly provided on the inner wall of the pressing groove, and a positioning rod 10 is fixedly provided through the spring 9. A plurality of positioning grooves 11 are provided on the inner wall of the rotating groove in a symmetrical arrangement around it. The end of the positioning rod 10 is inserted into the positioning groove 11. The positioning rod 10 is an L-shaped rod, and its end passes through the rotating groove and extends to the outside.

[0027] Both sides of the inner wall of the pressing groove are provided with sliding grooves 16, and the sliding plate 17 slides through the interior of two adjacent sliding grooves 16. The sliding plate 17 is fixedly inserted into the interior of the positioning rod 10.

[0028] When preparing for the sole molding process, the operator first places the rubber material on one of the molding modules 4 and closes the upper mold 1 and lower mold 2. Under the heat and pressure of the molding cavity 3 and molding module 4, the sole preparation is completed. Then, the operator presses the end of the L-shaped positioning rod 10 that extends out of the rotating groove. Under the pressure, the positioning rod 10 overcomes the elastic force of the spring 9 and disengages from the current positioning groove 11. At the same time, the slide plate 17 slides in the sliding groove 16 to ensure the stable movement of the positioning rod 10. Then, the crossbar 6 is rotated, which drives the rotating plate 5 and the two molding modules 4 to rotate. When the molding module 3 with the molded sole is rotated to the appropriate position, the positioning rod 10 is released, the spring 9 rebounds, and pushes the positioning rod 10 into the corresponding positioning groove 11 to fix the position of the molding module 4. At this time, the molded sole is located at the bottom, and the upper molding module 4 can be pressed down again by the upper mold 1 to close with the lower mold 2 and be molded. At the same time, the molded sole at the bottom is removed during the molding process, which reduces the time spent after the sole is molded and improves the production efficiency.

[0029] To facilitate the removal of the pre-molded shoe sole, such as Figure 1-3 As shown, a feeding ring 7 is fixedly provided at the bottom of the lower mold 2. The feeding ring 7 is connected to the through hole. An annular tube 12 is fixedly provided on the inner wall of the feeding ring 7. Multiple air outlets 13 are connected to the tube wall of the annular tube 12 and arranged symmetrically around it. The air outlets 13 are inclined and the openings of the multiple air outlets 13 are all facing the forming module 4. An air guide shroud 14 is fixedly provided through the side of the feeding ring 7. The air outlet of the air guide shroud 14 passes through the side of the feeding ring 7 and is connected to the annular tube 12. An air inlet fan 15 is fixedly provided on the outer wall of the air guide shroud 14.

[0030] Once the sole on a molding module 4 is formed, the molding module 4 is rotated using a rotation positioning mechanism to position the formed sole above the corresponding position on the unloading ring 7. Then, the air intake fan 15 is activated, drawing air into the air guide hood 14. The air then enters the annular pipe 12 through the air guide hood 14 and is blown out from the inclined air outlet pipe 13 facing the molding module 4. The airflow acts on the formed sole, generating a force that helps the sole detach from the molding module 4, allowing it to fall along the unloading ring 7 for easy collection by operators and quick part removal.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
