A kind of injection molded shoe with ventilation function and its manufacturing process

Abstract

The invention discloses a pair of injection molding shoes with an air exchange function and a manufacturing technology thereof. The pair of injection molding shoes comprises insoles, wherein a front foot sole part of a base plate of each insole is provided with a first hollow part, a foot heel part is provided with a second hollow part and an elastic cover cap, a plurality of through holes are uniformly formed in the edge of the second hollow part of the base plate of each insole, a removable air bag protecting sleeve bracket penetrates through the corresponding through hole from the upper surface of each insole and is embedded into the side wall of an air bag protecting sleeve to fix a soft air bag, an air exhaust hole of each soft air bag is connected with a connecting hole of an air guide front sole sheet by a first air guide pipe, one end of a second air guide pipe is connected with an air inlet hole of each soft air bag, the other end of each second air guide pipe is communicated with an air inlet hole of the inner side of a shoe sole, and a damping material layer is arranged between each soft air bag and the corresponding elastic cover cap. The manufacturing technology of the polyurethane upper connecting injection molding type respiratory air exchange shoes has the advantages that each special air bag protecting sleeve and the corresponding air bag protecting sleeve bracket are matched to support a soft air bag containing space; by utilizing a special shoe tree, the production technology of the polyurethane upper connecting injection molding type shoes is combined, the curing is performed after forming, and the pair of polyurethane upper connecting injection molding type health-care shoes with air exchange and sweet releasing functions is realized.

Description

technical field [0001] The invention relates to shoes that people wear daily, in particular to a manufacturing process of upper injection-molded shoes with ventilation function. Background technique [0002] The current shoes with breathing function generally use the mold to make the sole according to the pre-designed style, and at the same time, the ventilation mechanism is formed and installed in the airbag storage cavity and the air duct groove respectively, and then glued or stitched with the upper to form the shoe body . With the development of shoe-making technology, polyurethane injection-molded shoes with ventilation and perspiration functions have become a reality. The production method is generally to use injection molding to make the midsole and its air guide grooves, breathable grooves and Use special equipment or tools to punch out the air holes on the front sole of the insole for the protruding press hole at the heel, and then connect the midsole and the upper...

AI Technical Summary

Problems solved by technology

From the disclosure of the existing technology and shoemaking practice, we found that the midsole needs to be processed multiple times in order to seal the soft airbag on the sole; at the same time, high temperature will cause the airbag cavity to compress during the foaming process. , in order to avoid high temperature scalding the ventilation mechanism, a hard airbag must be used, which will result in a small working space and limited elasticity of the airbag, which will greatly affect the ventilation effect, resulting in unstable ventilation effect of the ventilation shoe function, or even failure to perform ventilation.
