Method and apparatus for preparing shoe through high-pressure injection molding

Abstract

The invention relates to a method and an apparatus for preparing a shoe through high-pressure injection molding. According to the present invention, a shoe top mold and a sole mold are combined to form a sole cavity, a material is injected into the injection molding port on the sole mold by a high-pressure injection molding spraying gun, and the radius of the injection molding port, the material injection flow rate, the material injection pressure, the material density, the friction coefficient of the injection molding port, the raw material falling point distance, the included angle between the inclination direction of the material injection port and the horizontal plane, and other process points are optimized, such that the preparation of the shoe through the high-pressure injection molding is achieved; and with the method and the apparatus, the production efficiency in the injection molding of the shoe is improved, the production cost is reduced, the filling pressure is large, the appearance of the gas eyes is avoided, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of injection molding shoemaking, in particular to a method and device for high pressure injection molding shoemaking. Background technique [0002] In the traditional injection molding shoe production line, a very important production process is the pouring of raw materials; the existing raw material pouring pressure should not be too high, and the flow rate of raw material pouring is low, so the production efficiency is low during the pouring process. The pouring pressure is low, and it is easy to trap air during the pouring process of the raw material, so air holes are easy to form on the surface of the raw material, which affects the product quality. [0003] It is difficult to control the pouring stroke and position of injection molding shoes, and it is difficult to implement consistency in pouring. Existing production techniques and devices will not be able to realize high-pressure injection molding sh...
