Abstract

A lightweight injection molded shoe midsole comprises a shoe midsole body formed by injection molding, wherein a plurality of empty slots are arranged at intervals in the vertical and horizontal directions at the forefoot portion of the shoe midsole body; the empty slots are covered with a hard cardboard embedded in the upper forefoot portion of the shoe midsole body. The utility model adopts a structure in which the empty slots cover the hard cardboard at the forefoot portion of the injection molded shoe midsole, which can greatly reduce the weight of the injection molded shoe midsole, achieve the purpose of lightweighting, and make the finished shoes made by the utility model lighter, providing users with better wearing comfort.

Description

A lightweight injection molded shoe midsole

technical field

The utility model relates to a shoe midsole, in particular to a lightweight injection molding shoe midsole.

Background technique

The midsole is an important part of the sole. There is an injection-molded midsole, which has the characteristics of convenient production and a high degree of standardization. However, the midsole made of plastic material is heavy, especially with a thick waterproof platform. The midsole of the shoe is heavier, and the weight is concentrated on the waterproof platform, so that when people walk in the finished shoes made of this midsole, it is easy to cause sore feet and fatigue.

Contents of the invention

The purpose of the utility model is to provide a lightweight injection molding shoe midsole, which has the characteristics of light weight.

In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a lightweight injection-molded shoe midsole, including a shoe midsole body integrally formed by injection molding, and a plurality of vertical and horizontal intervals arranged on the forefoot of the shoe midsole body. Empty slot; the empty slot is covered with a hard cardboard embedded in the upper part of the forefoot of the midsole body of the shoe.

Because the shoe midsole body is integrally formed by injection molding, in order to facilitate the demoulding of the hollow groove, the shape of the hollow groove is a triangular prism with two bottom faces concave inward.

Considering the degree of light weight and wearing comfort comprehensively, the width of the top of the partition between adjacent empty slots is 2.5 to 6 mm, preferably 4.5 mm.

The utility model adopts a structure in which the forefoot of the midsole of the injection-molded shoe is covered with a hard cardboard, which can greatly reduce the weight of the mid-sole of the injection-molded shoe, achieve the purpose of light weight, and make the finished shoe made by the utility model lighter , to provide users with better wearing comfort.
