Description

Technical Field

[0001] This utility model relates to the field of shoe sole mold technology, specifically to a popcorn shoe sole mold. Background Technology

[0002] Popcorn-shaped shoe soles, with their unique appearance and excellent elasticity and cushioning performance, are loved by a wide range of consumers. Currently, the molds used in the production process of popcorn shoe soles have some problems. Existing mold structures are often relatively simple, making it difficult to precisely control the arrangement and bonding degree between popcorn particles during the sole molding process. This results in uneven density and performance of the sole, affecting the overall quality of the sole. Furthermore, during demolding, the strong adhesion between the sole and the mold can easily damage the sole surface, reducing the product yield. Additionally, the mold has low cooling efficiency during use, prolonging the production cycle and increasing production costs. Therefore, we propose a popcorn shoe sole mold. Utility Model Content

[0003] In view of the problems existing in the current popcorn shoe sole mold, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a popcorn shoe sole mold, which solves the problems of existing molds having relatively simple structures, making it difficult to accurately control the arrangement and bonding degree between popcorn particles during the sole molding process, resulting in uneven density and performance of the sole, affecting the overall quality of the sole, and during demolding, the large adhesion between the sole and the mold can easily damage the sole surface, reducing the product qualification rate. At the same time, the mold has low cooling efficiency during use, which prolongs the production cycle and increases production costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A popcorn shoe sole mold includes an upper mold, a lower mold, and a fixing plate. The surfaces of the upper mold and the lower mold are provided with shoe sole forming cavities. Multiple positioning posts are fixedly installed on the bottom surface of the upper mold. Multiple positioning grooves are provided on the surfaces of the lower molds. The positions of the multiple positioning posts correspond to the positions of the multiple positioning grooves. The bottom of the lower mold is provided with multiple evenly distributed ventilation holes.

[0022] This utility model discloses a popcorn shoe sole mold.

[0023] This utility model provides, for example Figure 1-3 The popcorn shoe sole mold shown includes an upper mold 1, a lower mold 2, and a fixing plate 3. Both the upper mold 1 and the lower mold 2 have shoe sole forming cavities 4 on their surfaces. Multiple positioning posts 5 are fixedly installed on the bottom surface of the upper mold 1, and multiple positioning grooves 6 are provided on the surfaces of the lower mold 2. The multiple positioning posts 5 correspond to the positions of the multiple positioning grooves 6. The bottom of the lower mold 2 has multiple evenly distributed ventilation holes 7. A vacuum pump 8 is fixedly installed on the bottom of the lower mold 2, and the multiple ventilation holes 7 are connected to the vacuum pump 8. The vacuum pump 8 can create a negative pressure environment in the shoe sole forming cavity 4, so that the popcorn particles can be arranged and combined more tightly during the forming process.

[0024] This utility model discloses a popcorn shoe sole mold. The upper mold 1 and the lower mold 2 are both equipped with cooling pipes 9 inside. The two cooling pipes 9 are respectively located near the shoe sole forming cavity 4, and the two cooling channels are distributed in a serpentine pattern. A chiller 10 is fixedly installed on one side of the upper mold 1 and the lower mold 2. The two ends of the two cooling pipes 9 are respectively fixedly connected to the two ends of the two chillers 10, which can quickly cool the mold, improve cooling efficiency, and shorten the production cycle.

[0025] This utility model discloses a popcorn shoe sole mold. Multiple support columns 11 are fixedly installed on the top of the upper mold 1. A top plate 12 is fixedly installed on the top of each support column 11. A telescopic rod 13 is fixedly installed on the bottom of the top plate 12. A fixing plate 3 is fixedly installed on the moving end of the telescopic rod 13. Multiple demolding columns 14 are fixedly installed on the bottom of the fixing plate 3. All demolding columns 14 penetrate the upper mold 1 and extend into the shoe sole forming cavity 4. Rubber pads 15 are fixedly installed on the bottom of each demolding column 14 to facilitate demolding.

[0026] This utility model discloses a popcorn shoe sole mold, wherein the diameter of the plurality of ventilation holes 7 is 0.5-1.5mm, which can both ensure the negative pressure effect and prevent popcorn particles from entering the ventilation holes.

[0027] In use, popcorn kernels are first placed into the sole forming cavity of the lower mold 2. Then, the upper mold 1 and the lower mold 2 are closed. Through the cooperation of the positioning pin 5 and the positioning groove 6, the position of the popcorn kernels in the sole forming cavity 4 is precisely controlled. Next, the vacuum pump 8 is started to create a negative pressure environment in the sole forming cavity 4, so that the popcorn kernels are arranged and combined more tightly. During the sole forming process, the chiller 10 is started, and the cooling medium is cooled through the cooling pipe 9 to accelerate the sole forming process. After the sole is formed, the telescopic rod 13 is started. The telescopic rod 13 drives the demolding pin 14 to move downward through the fixed plate 3, pushing the formed sole out of the mold and completing the demolding operation.
