Method for making shoe soles

Abstract

The shoe sole making process includes the following steps: making one mold with mold cavity in the shape of shoe sole and at least one hole to outside and flat part around the hole; making one insert; setting the insert into the mold cavity and vacuum pumping the mold cavity through the hole for the insert to contact with the flat part; pouring or injecting plastic material into the mold cavity; curing and demolding to form shoe sole.

Description

technical field [0001] The present invention relates to shoe soles, in particular to a manufacturing method for shoe soles. Background technique [0002] Commercially available air-cushioned shoes, because an airbag made of elastic material is embedded in the outsole of the shoe, it can greatly absorb the shock generated by the user during intense exercise, so the load on the user's ankle will also be reduced a lot , and thus reduce the possibility of sports injuries, and thus make air-cushioned shoes widely loved by consumers and become a mainstream product in the market. [0003] refer to Figure 11 to Figure 13 , the manufacturing method of the existing shoe sole is to prepare two first and second mold bases 81, 82 and an airbag 83 for forming the top and bottom surface of a shoe sole 80, and the inner side wall of the first mold base 81 is at the corresponding heel Two side plugs 811, 812 are protrudingly provided to define two hollow holes 84 on both sides of the sole ...

AI Technical Summary

Problems solved by technology

[0004] The manufacturing technology of the above-mentioned shoe bottom material outsole is quite mature so far, but the airbags 83 are made of elastic material, so that the external dimensions of each airbag 83 are slightly different, so when different airbags 83 are located on the first When the mold base 81 is used, sometimes there will be a gap between the air bag 83 and each side plug 811, 812, so that the shoe sole will produce the overflow phenomenon commonly known as burr a during the above-mentioned manufacturing process. Therefore, the manufacturer must use chemical solvents for secondary Only one cleaning process can remove the burrs a that affect the appearance of the sole 80. In this way, the chemical solvent not only has the doubt of corroding the airbag 83, but also must spend extra manpower to remove the burrs a, which will greatly increase the production cost of the sole 80; , Chemical solvents are also harmful to human health after being inhaled
