Sole Manufacturing Mold

Abstract

A shoe sole manufacturing mold includes a bottom mold (10) and left and right molds (20, 30). A positioning part (201) is provided at an appropriate position on the top of the left and right molds. The positioning part is concave and has a space. The outer layer is covered with a protective body (202) of appropriate thickness, and a convex rib (203) is provided at an appropriate position below the positioning portion. By means of the protective body and the convex rib, when the shoe upper is put into the mold for the filling molding of the shoe sole, the material of the shoe sole is prevented from overflowing to the edge of the shoe shoe upper.

Description

technical field [0001] The invention relates to an improved structure of a shoe-making mould, in particular to an improved structure of a shoe-sole manufacturing mould, which utilizes the setting of a protective body and a convex rib to achieve the one-time completion of shoe-sole manufacturing. Background technique [0002] Existing shoe sole mold structure, please refer to figure 1 Shown, mainly comprise a base mold 1 roughly in the sole shape, and be provided with the recessed part of predetermined shape sole pattern on its top surface, be provided with the left and right mold 2 that can lean inward respectively inwardly on both sides of base mold 1, utilize After the shoe last is put on a shoe upper 3, the shoe last is made to fit downwards on the bottom mold 1, and then the left and right molds 2 are pressed inward to form a fabric for forming a shoe sole. In the space 4, the raw materials are injected and cooled to form a shoe body structure in which the upper 3 and t...

[0002] Existing shoe sole mold structure, please refer to figure 1 Shown, mainly comprise a base mold 1 roughly in the sole shape, and be provided with the recessed part of predetermined shape sole pattern on its top surface, be provided with the left and right mold 2 that can lean inward respectively inwardly on both sides of base mold 1, utilize After the shoe last is put on a shoe upper 3, the shoe last is made to fit downwards on the bottom mold 1, and then the left and right molds 2 are pressed inward to form a fabric for forming a shoe sole. In the space 4, the raw materials are injected and cooled to form a shoe body structure in which the upper 3 and the sole 31 are integrally formed. Due to the lack of space, when the entire set of molds are injected, there will be uneven injection and raw materials overflowing and contaminating the shoe upper, resulting in defective products or need to be processed after the injection is completed. Trimming, in addition, in order to make the material overflow less serious, the left and right molds 2 must be made to fit the shoe upper 3 quite closely. In the course of operation, it is unavoidable that there will be scratches and damage to the surface of the shoe upper 3, resulting in a decrease in the manufacturing yield. Therefore, the manufacturing yield is low, uneven injection, raw material overflow, serious damage to the upper The lack of high cost has always been a part of the industry that needs to be improved.
