Description

Technical Field

[0001] The utility model relates to an injection shoe mould and belongs to the technical field of injection shoe production. Background Art

[0002] Injection-molded shoes are shoes produced through the injection molding process. Injection molding involves injecting heated, molten plastic into a mold and then cooling it to create various products. In the production of injection-molded shoes, synthetic plastics (such as TPU and EVA) are commonly used. These materials offer excellent flexibility, wear resistance, and lightweight properties, making them suitable for soles or entire shoes.

[0003] A Chinese utility model patent, "An Injection Shoe Mold," with announcement number CN220163083U, discloses an injection shoe mold, specifically relating to the field of injection shoe production. The top of the base support is fixedly connected to a limit plate, the outer wall of which is provided with a threaded hole. A threaded reinforcement rod is connected through the interior of the limit plate. One end of the threaded reinforcement rod is fixedly connected to a rotary wheel, and the other end of the threaded reinforcement rod is fixedly connected to a clamping plate. A heat dissipation strip is fixedly connected to the top of the base support, and an anti-scalding handle is fixedly connected to the outer wall of the base support. The top of the base support is snap-fitted with a mold assembly, which internally includes a shoe mold box, an operating handle, a rotating shaft, an injection hole, and a magnetic anti-sticking film. The utility model supports and clamps the mold assembly through the base support, uses the base support for thermal insulation, and provides anti-scalding treatment for transportation and transfer of the mold assembly, facilitating safe injection molding production. The mold assembly can also be clamped for mold assemblies of different sizes, making it applicable to a wider range of applications.

[0004] In the aforementioned patent, a threaded hole is provided in the limiting plate, into which a threaded reinforcement rod is threadedly connected. A rotary wheel is fixedly connected to one end of the threaded reinforcement rod, and a clamping plate is fixedly connected to the other end. By rotating the rotary wheel, the threaded connection between the threaded reinforcement rod and the threaded hole is driven to move the clamping plates away from or toward each other, thereby clamping and loosening the mold assembly. However, rotating the rotary wheel to rotate the threaded reinforcement rod, thereby clamping and securing the mold assembly with the clamping plate, requires simultaneous twisting and a consistent number of rotations to clamp the mold assembly to the top center of the base assembly, making this method of clamping and securing rather cumbersome. Therefore, the present invention proposes an injection shoe mold to address the aforementioned problem. Utility Model Content
