Manufacturing method of middle sole and middle sole

Abstract

The invention discloses a manufacturing method of a middle sole. The manufacturing method comprises the following steps of step (1) preparation of a resin mixture: stirring resin and a curing agent in a container for mixing; step (2) pre-impregnation of glass fiber cloth: impregnating the resin mixture prepared in the step (1) on the glass fiber cloth; step (3) cutting of the glass fiber cloth: cutting the glass fiber cloth pre-impregnated in the step (2) for later use according to the shape of a preset semi-inserted middle sole or the middle sole; and step (4) hot pressing and forming: putting the glass fiber cloth cut in the step (3) into a preheated mold, carrying out hot pressing on the glass fiber cloth cut in the step (3) and obtaining a middle sole product. The invention also discloses the middle sole and a shoe containing the same according to the manufacturing method. The middle sole disclosed by the invention has the advantages of high strength, less thickness, light weight, moisture and hydrolysis resistance, lasting sizing, strong weather resistance, high balance and convenience for shoemaking standardization and the like.

Description

technical field [0001] The invention relates to the field of shoe manufacturing technology, in particular to a method for manufacturing a shoe midsole, and the invention also relates to a shoe midsole manufactured according to the above manufacturing method and a shoe including the shoe midsole. Background technique [0002] Usual soles include a midsole and a large bottom, wherein the midsole is a layer of material located on the large bottom, see the Chinese Invention Patent Application Publication No. 200410026765, which discloses "the making of a shoe midsole Method", the technical solution proposed in the patent application for this invention is: firstly make the middle part, and then place the finished shoe midsole in the center of the shoe midsole mold, inject PU material into the mold space around the middle part by injection molding Inside, the outer edge is formed, and the outer edge and the middle part are fixed together by injection molding; finally, the finished...

AI Technical Summary

Problems solved by technology

[0005] 1. Since the shoe-setting midsole of the prior art is made of paper material, it is easy to soften when it is wet, and it is easy to be damaged when it meets water, thus losing the shape and support of the shoe;

[0006] 2. The shaped midsole of shoes in the prior art is only supported by a steel core with a width of about 14 mm, which cannot make the whole sole of the foot fully balanced;

[0007] 3. The stereotyped midsole of the shoe in the prior art, because its material is a paper material, the thickness and weight of the finished shoe midsole cannot be reduced, so that the wearing comfort and the aesthetic appearance of the shoe are affected;

[0008] 4. The connection mode of the shoe-shaped midsole in the prior art is glued and fixed, then cold-pressed and bonded, which cannot be accurately matched with the shoe mold, which also affects its standardization and standardization in the mass production process of shoes, which is easy to leading to an increase in defective
