Injection molding process for substitute material insole applied to field of shoemaking

Abstract

The invention discloses an injection molding process for a substitute material insole applied to the field of shoemaking. The injection molding process comprises the steps of splitting a material part at the one half of the thickness of the material part by a splitting knife, and splitting to the part 5mm behind the plantar toe line from the heel; digging an injection molding hole in the side in which the material part is combined with the outsole by drilling equipment; putting the insole into an injection molding mould, enabling the front part of the insole to be in accordance with a shoe support in shape by the pressure of the mould, and injecting polyethylene through the injection molding hole; and enabling the upper layer insole to be opened upwards under the action of injection pressure until the mould is fully injected. The molding process is specially used for processing the substitute material, and the quality of the substitute material meets the requirement for the insoles of shoes, so that the quality of the shoes can be guaranteed, the shoes are comfortable to wear, and the problems that an existing special molding process is not suitable for the processing of the substitute material, and after a traditional technology is adopted, the insole is easily broken, and the structure of the insole is influenced, so that the quality of the shoes can be damaged can be solved.

Description

technical field [0001] The invention relates to a process, in particular to an injection molding process using an inner sole of a substitute material in the field of shoemaking. Background technique [0002] Shoes are things made of leather, cloth, wood, grass, plastic silk, etc. that are worn on the feet and land on the ground when walking. Shoes have a long history of development. About 5,000 years ago in the Yangshao culture period, the most primitive shoes made of animal skins appeared. Shoes are a tool for people to protect their feet from injury. The earliest people invented fur shoes in order to overcome special circumstances and prevent their feet from being uncomfortable or injured. Shoes have developed to the present, and they have formed what they are now. Shoes of various styles and functions can be seen everywhere. In traditional Chinese wedding customs, shoes are a kind of mascot, which is a symbolic folk custom produced by the pairing of shoes and the homo...
