[0002] Shoe sole molds are the core tools used to produce shoe soles, and their design and manufacturing directly affect the shape, size, and functionality of the shoe sole.

[0003] In existing shoe sole molds, the sole mold groove and the mold body are integrally formed, and the heel height or arch height of the sole produced is a fixed value. If the user has a need for height increase or arch correction, the manufacturer needs to open a separate mold for the same sole, which is inconvenient. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a shoe sole mold for one-time production of multiple soles. This solves the problem that existing shoe sole molds have an integral molded structure where the sole mold groove and the mold body are integrally formed, resulting in a fixed value for the heel height or arch height of the soles produced. In the same shoe sole, if the user has a need for height increase or arch correction, the manufacturer needs to open a separate mold, which is inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shoe sole mold for one-time production of multiple soles, comprising a lower mold, an upper mold, and an injection adjustment block. The top surface of the lower mold is provided with at least one lower sole mold groove, and the lower sole mold groove has a height adjustment opening at the heel or arch. The bottom surface of the lower mold is provided with a disassembly groove communicating with the height adjustment opening. The upper mold is connected to the lower mold in an openable and closable manner. The bottom surface of the upper mold is provided with an upper sole mold groove adapted to the lower sole mold groove. The upper sole mold groove and the lower sole mold groove form a sole forming chamber. The injection adjustment block is tightly fitted into the disassembly groove, and the injection adjustment block is provided with an injection positioning component that is sealed and embedded in the height adjustment opening and injects into the sole forming chamber.

[0006] Furthermore, in order to improve the overall compactness of the mold, the shape and size of the injection adjustment block are perfectly matched with the disassembly groove, and the outer wall of the injection adjustment block is provided with a fixing component for connecting and fixing with the disassembly groove.

[0007] Furthermore, for ease of disassembly and assembly, the fixing component includes a bolt groove located on the outer wall of the injection molding adjustment block and a fixing bolt embedded in the inner wall of the bolt groove. The fixing bolt is horizontally positioned and its threaded end is threadedly connected to the inner wall of the disassembly and assembly groove.

[0008] Furthermore, in order to combine the adjustment structure with the injection molding structure, the injection positioning component includes an injection channel and a sealing adjustment component. One end of the sealing adjustment component is sealed and embedded in the height adjustment slot, and the other end is connected to the injection channel. The center of the sealing adjustment component is provided with a hole that matches the injection channel. The end of the sealing adjustment component away from the injection channel forms a heel injection groove or arch injection groove between it and the opening of the height adjustment slot.

[0009] Furthermore, to improve the strength of the connection, the sealing adjustment component and the injection molding adjustment block are integrated into one structure.

[0010] Furthermore, in order to facilitate disassembly and replacement, the sealing adjustment component and the injection molding adjustment block are fixedly connected by bolts.

[0011] The beneficial effects of this utility model are: the lower mold in the shoe sole mold has an injection positioning component, which adopts a combination of injection molding and mold groove adjustment structure. When making the same shoe sole, a single mold can meet the user's height increase or arch correction needs, and the manufacturer does not need to open a separate mold, thus improving the convenience of production.
