Molding method for shoes with multi-color shoe soles

Abstract

The invention provides a molding method for shoes with multi-color shoe soles. The molding method comprises the following steps that a thermoplastic polyurethane elastomer raw material for forming outsoles is added into an injection molding machine for injection molding after being baked, and the injection-molded thermoplastic polyurethane elastomer raw material is cooled to obtain the outsoles; after being baked, a polyol raw material and an isocyanate raw material for forming first insoles are mixed with first pigment to form a first polyurethane raw material, the first polyurethane raw material is added into the injection molding machine, and each first insole is formed on the corresponding outsole, wherein each first insole has a first color; each of uppers is fixed onto a mould by clamping, after being baked, a polyol raw material and an isocyanate raw material for forming second insoles are mixed with second pigment to form a second polyurethane raw material, the second polyurethane raw material is added into the injection molding machine, and each second insole connecting corresponding first insole with the corresponding upper is formed between the edge of the first insole and the edge of the upper, wherein each second insole has a second color; and mold release is performed after the mold is opened to obtain the shoes with the multi-color shoe soles. The shoes are not prone to degum, and are more attractive.

Description

technical field [0001] The invention relates to a molding method of shoes, and specifically provides a molding method of shoes with multi-color soles. Background technique [0002] Shoes are an indispensable article in people's daily life. With the improvement of material living standards, modern people have put forward higher and higher requirements for the beauty, comfort and diversity of shoes. The sole is an important part of the shoe, used to support the sole of the foot, and the material, shape and workmanship of the sole largely determine the comfort of the shoe. [0003] The sole is usually made of polyurethane material, which has the advantages of light weight and good wear resistance. In existing shoes using polyurethane soles, the soles are usually bonded to the upper surface of the shoes by applying glue, which is not environmentally friendly and is easy to unglue. Moreover, most of these polyurethane soles are of a single color. In order to mix multiple colors...

In the existing shoes with polyurethane soles, the soles are usually bonded to the upper surface of the shoes by applying glue, which is not environmentally friendly and easy to open the glue

Moreover, most of these polyurethane soles are of a single color. In order to mix multiple colors, it is usually sprayed on the surface with a color paste after the sole is formed. The diversity of colors and shapes is limited, which is not conducive to wearing and matching.
