Forming technology and preparation method of bicolor sole

Abstract

The invention relates to the field of soles, and provides a forming technology and preparation method of a bicolor sole which has simple forming technology and high production efficiency. According to the bicolor sole which is produced by utilizing the forming technology, the bicolor sole is free from debonding and delaminating as the shoe undersole and the shoe insole are combined firmly, and the service life is long. The forming technology and preparation method of the bicolor sole, provided by the invention, relates to the following steps of: material preparing-pelleting-injection-forming preparing-injection forming-foaming-punching-milling expanding-oil pressing.

Description

technical field [0001] The invention relates to the field of shoe soles, in particular to a molding process and a preparation method of a two-color shoe sole. Background technique [0002] China is the world's largest producer and exporter of footwear. Footwear has become a major pillar of China's economy. With the development of society, the functional requirements of various industries for footwear are becoming more and more diversified, especially for soles. Performance requirements are getting higher and higher. The sole usually includes the outsole and the midsole. Traditionally, the outsole and the midsole are usually the same color, which cannot meet the needs of modern people. The molding method of the sole is usually to shape the outsole and the middle and bottom respectively, and then glue them together. The process is more complicated.

The sole usually includes the outsole and the midsole. Traditionally, the outsole and the midsole are usually the same color, which cannot meet the needs of modern people. The molding method of the sole is usually to shape the outsole and the middle and bottom respectively, and then glue them together. The process is more complicated. After the outsole and the midsole are formed separately, they need to be bonded together manually with an adhesive. During the bonding process, the volatilization of the adhesive components will affect the The environment is polluted, it is not environmentally friendly, and it has great harm to the health of the workshop staff. In addition, the outsole and midsole bonded together by adhesives are not firmly bonded, and they are easy to degummed when exposed to water, causing shoes The service life is short, and the process of manual bonding is cumbersome, time-consuming, and the production efficiency is low. Moreover, due to the uneven force of manual operation, the error of human operation is large, and the rate of defective products is high.
