Abstract

The invention relates to an EVA in-mold bubble one-time forming mold and a forming method. Foot-shaped inserts matched with lower mold cavities to form sole bulges are arranged on a lower mold plate,five protruding blocks used for forming an anti-skid concave face are arranged on the areas, corresponding to the toe portions of a foot, of the upper surface of each foot-shaped insert, first concavecavities are formed in the area, corresponding to the forefoot part of the foot, of the upper surfaces of the foot-shaped inserts, second concave cavities are formed in the inner side and the outer side of the area, corresponding to the arch part of the foot, of the upper surfaces of the foot-shaped inserts correspondingly, third concave cavities are formed in the area, corresponding to the heelpart of the foot, of the upper surfaces of the foot-shaped inserts, and arc-shaped concave parts matched with the lower mold cavity to form upper forming channels are arranged on the foot-shaped inserts. The forming mold is conveniently used for one-time forming of shoes made of EVA materials.

Description

technical field [0001] The invention relates to a mold for one-time forming of air bubbles in an EVA mold and a forming method. Background technique [0002] EVA refers to "ethylene-vinyl acetate copolymer" and its rubber and plastic foaming materials, with molecular formula (C2H4)x.(C4H6O2)y, which has good cushioning, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, It has the advantages of anti-bacterial and waterproof, non-toxic, and non-absorbent. It is often used to make refrigerator conduits, gas pipes, civil engineering plates, containers, and daily necessities. [0003] There are often soles made of EVA material on the market, and the soles made of EVA material usually need multiple injection moldings to be formed during the manufacturing process, especially for slippers, which makes the manufacturing process complicated and inefficient. For this reason, need a kind of EVA in-mold air bubble one-time molding mold. Contents of...
