shoe injection molding method

Abstract

The invention discloses an injection moulding method of shoes, and solves the problem that the quality of injection moulded shoes cannot be guaranteed due to the fact that only injection moulded shoes a with two-layer structure can be produced through a conventional shoe mold. The adopted method comprises the steps that a prefabricated shoe outer layer is connected on an inner last in a sleeving manner; a prefabricated shoe inner layer is connected on the inner last in a sleeving manner; a through hole is formed in the shoe outer layer; a gasket is stuffed into the through hole, or a plurality of strip-shaped convex bodies are processed on the upper end face of the inner last; after mold assembly, an injection molding opening in a movable mold and a nozzle in the gasket are matched through socket connection; or the injection molding opening is inserted into the through hole; the space between the shoe outer layer and the shoe inner layer is filled with materials through utilizing an injection molding machine; after the materials are solidified, a shoe interlayer of a shoe upper is formed; and then, a shoe sole is processed at the bottom of the shoe upper.

Description

technical field [0001] The present invention relates to a method of manufacturing shoes, in particular to a method for injection molding a shoe having a multilayer structure. Background technique [0002] Usually, the existing injection molded shoes generally have a two-layer structure, that is, an inner layer of a shoe and an outer layer of a shoe, and the inner layer of a shoe is generally made of cloth as an insulating layer. This type of shoe is prepared and molded by a forming mold. The structure of the existing forming mold includes a base, a left movable mold and a right movable mold are hinged on one end of the base, and an inner last is fixed at the middle of the base. The upper end of the last is molded into a human foot-like foot. When making the preparation, first put the inner layer of the shoe on the inner last, close the left movable mold and the right movable mold, use the injection molding machine to inject materials into the mold cavity, and form a shoe up...

AI Technical Summary

Problems solved by technology

And the appearance of shoes is determined by the outer layer of the shoe. The existing shoe forming mold can only inject the outer layer of the shoe. It will increase the production cost of the mold, and on the other hand, the modeling method is single, and the aesthetics of the obtained shoes will be limited.

In addition, the outer layer of the shoe must take into account the requirements of aesthetics, firm bonding, and anti-aging requirements. These requirements are superimposed on the same material, and the characteristics of the same material are unlikely to meet these requirements at the same time. , that is, the requirements of all aspects of this shoe can not be well met
