Foamed sole forming method, and mold and sole structure

Abstract

The invention provides a foamed sole forming method, and a mold and a sole structure. The foamed sole forming method comprises the steps of: initial foaming, specifically, an initial foaming mold is filled with foaming particles containing a foaming agent, and indirect heating and mold closing are performed to enable the foaming particles to be foamed into a semi-finished foamed sole, and the semi-finished foamed sole is extracted from the initial foaming mold; high temperature forming, specifically, the semi-finished foamed sole is placed in a high-temperature forming mold, the mold cavity ofthe high temperature forming mold is provided with bumps in which fluid holes are formed, high temperature gas enters the mold cavity through the fluid holes to expand the semi-finished foamed sole,the surface of the semi-finished foamed sole is compressed by the bumps to form grooves, the surfaces of the grooves extend into the fluid holes to form guide posts, then cooling water enters the moldcavity through the fluid holes so that the semi-finished foamed sole contracts, mold closing is performed to compress the semi-finished foamed sole, the structures with the guide posts and the grooves are arranged and combined to form the foamed shoe with a recognizable stereoscopic pattern, and the foamed shoe is taken out from the high-temperature forming mold.

Description

technical field [0001] The invention relates to a foamed shoe sole combined with the bottom of shoes, in particular to a molding method of the foamed shoe sole, a mold and a structure of the shoe sole.

Problems solved by technology

However, when the finished shoes are finally sold, the finished product produced by a single manufacturer can only be recognized by the trademark on the appearance of the product, and its various accessories cannot be provided to consumers.

In addition, there are also businessmen who purchase shoe accessories of the same size and specifications from multiple manufacturers and assemble them into shoes of the same model and type. It is impossible to easily tell which third party made the semi-finished or finished product from the appearance alone. The product serial number, volume Distinguish by standard
