Multicolor foaming method and device thereof

Abstract

The present invention is multicolor foaming process and apparatus. The multicolor foaming process includes the steps of preparing materials, mixing, injection molding, heating to form, demolding, and cooling to set the foamed product with different mixed colors. The multicolor foaming apparatus includes mainly two or more large material barrels for holding materials of different colors, medium sized material barrels for holding materials in certain ratio, one material feeding tank with material channels for feeding foaming materials of different colors, and one pressurizing part to extrude foaming material into the mold for forming the multicolor product through the subsequent processing. The present invention can produce multicolor foamed product and easy coloring.

Description

technical field [0001] The invention relates to a multi-color foaming method and a device thereof. Background technique [0002] Among the finished products manufactured by foam molding technology, footwear is the most common type. Human beings evolved to stand on two feet to free up their hands to create civilization. Therefore, the burden of the whole body weight must be borne by the feet and even the feet. , so it is necessary to wear all kinds of shoe bodies to relieve the pressure and friction between the feet and the ground. This shows the importance of the shoe body. The manufacturing and design methods of various shoe bodies have always been the goal of research and development by manufacturers. [0003] Existing foamed shoe bodies, please refer to the Taiwan Patent Certificate No. M222926 "Manufacturing Method of In-Mold Foamed Shoes", which mainly makes shoe bodies by injection molding of foamed materials. Although the method has the advantages of simple steps and...

[0003] Existing foamed shoe bodies, please refer to the Taiwan Patent Certificate No. M222926 "Manufacturing Method of In-Mold Foamed Shoes", which mainly makes shoe bodies by injection molding of foamed materials. Although the method has the advantages of simple steps and easy manufacture, it is limited by the foam material, so it only has a single color. The required color of the foam material must be prepared first during production, and the finished product after injection molding also has only a single color. Color, in order to avoid being monotonous, if you need multiple colors, you need to process and paint again after molding, but the coloring after molding is not only easy to fall off, but also the irregular shape of the shoe body is not convenient for the coloring step, so On the whole, its practicality is poor
