GPU shoe sole full-automatic pouring forming device and preparation method

Abstract

The invention discloses a GPU sole full-automatic pouring forming device and a preparation method, the pouring forming device comprises a sole mold, a vacuum machine table, an automatic pouring mechanical arm and a controller, the GPU sole comprises an outsole formed by GPU liquid injection molding and a decorative layer formed on the bottom surface of the outsole, and the GPU liquid is formed by mixing a liquid A and a liquid B according to the volume ratio of 100: (60-90); by limiting the preparation device and the preparation method of the GPU shoe sole, the prepared GPU shoe sole is light, thin, high in wear resistance and good in yellowing resistance, attractive patterns or colors can be formed on the side wall and the bottom of the shoe sole, the overall preparation method is simple, the forming temperature is low, and low-carbon manufacturing is achieved.

Description

technical field [0001] The invention belongs to the field of sole preparation, and in particular relates to a GPU sole automatic infusion molding device and a preparation method. Background technique [0002] In the 20th century, with the development of China's manufacturing industry, China's footwear industry has developed rapidly and has become the world's major footwear manufacturing base. And in recent years, the demand for products in the sole field has changed a lot. The requirements for physical properties are already the foundation, and the requirements for technological content, technological highlights, and green environmental protection attributes are more prominent. [0003] The printing sole is to print the pattern or color on the inside and outside of the sole by transfer printing or color spraying, so as to make the sole more beautiful and meet people's pursuit of high-quality life. However, the printed soles produced by the color spraying process have a sing...

AI Technical Summary

Problems solved by technology

However, the printed soles made by the color spraying process have a single color and simple patterns, and cannot make colorful, complex and fine patterns, and are easy to decolorize, especially the patterns printed on the outside of the soles. Friction and discoloration are the most serious, and when the pattern or color is on the inner surface of the sole, the sprayed ink cannot fit the sole or upper, resulting in degumming

In addition, the existing two-component polyurethane printing sole molding process can only be used to produce traditional flat soles, and cannot produce printed soles with side walls, which needs further improvement
