Description

Technical Field

[0001] The utility model relates to the field of shoe body processing structures, and particularly relates to a shoe body cover plate mold. Background Technique

[0002] The cover plate used in sewing the shoe upper of the shoe body cover plate mold mainly functions to provide support and prevent the material from moving during sewing. Common cover plate materials include acrylic plates, polycarbonate, aluminum plates, hard plastics, and fiberglass composite materials, etc. These materials have their own advantages and disadvantages. For example, acrylic plates and polycarbonate have high transparency and wear resistance, while aluminum plates have a lighter weight and good thermal conductivity.

[0003] In the existing shoe body cover plate mold, there is a large gap between the cover plate and the shoe body when sewing the shoe upper. During sewing, the material is squeezed and is prone to bulging, which not only affects the appearance quality of the product but also may lead to an increase in the rework rate, thus reducing the production efficiency. Therefore, a new type of shoe body cover plate mold is needed at this time, which can design a thermoplastic deformation pressing piece in the area where bulging may occur to effectively solve this problem. At the same time, when the pressing piece is damaged after long-term use, it can be quickly replaced, improving the overall practicality. Summary of the Utility Model
