preparation example Construction

[0048] The embodiment of the present invention provides a kind of preparation method of above-mentioned sports shoe sole, comprises the following steps:

[0049] An upper bottom blank and a lower bottom blank are respectively provided; the upper surface of the upper bottom blank covers the entire sole of the foot, and a plurality of grooves are reserved in the lower bottom blank, and the plurality of grooves are located at the first far The metatarsal to the first metatarsal and the second middle phalanx area, the metatarsal area of ​​the forefoot, and the calcaneal area at the heel;

[0050] Assemble the upper and lower base blanks, place chemical foaming agents or physical barrier substances in the reserved multiple grooves, and then fire them to form a plurality of closed air cavities The midsole is finally prepared to obtain the sole of the sports shoe.

[0051] In the embodiment of the present invention, the upper bottom blank and the lower bottom blank are respectively ...

Embodiment 1

[0060] Through the injection machine, the upper and lower bottom blanks are prepared respectively. The upper bottom blank is correspondingly formed into an upper bottom part, and its upper surface shape covers the entire sole of the foot; the lower bottom blank is correspondingly formed into a lower bottom part. Wherein, the lower bottom blank is reserved with a plurality of grooves, which correspondingly form a closed air cavity, which is located at the first distal phalanx to the first metatarsal and the second middle phalanx, the forefoot metatarsal area, and the heel at the heel. bone area. The materials of the upper bottom blank and the lower bottom blank are all EVA, which is called the injection foam bottom rubber material, which belongs to the IP formula, and the specific gravity of the material is 0.40g / cm 3 .

[0061] Assemble the obtained upper bottom blank and lower bottom blank, place 0.6g PU film (thickness about 0.2mm, polymerization degree between 200-400, mo...

Abstract

The invention provides a sole for sports shoes and a preparation method and application thereof. A midsole of the sole herein includes: an upper sole component and a lower sole component; the upper sole component is a foam component having the upper surface covering the whole foot sole and a foam component and positioned in the position the closest to the foot sole; the lower sole component is a foam component having the lower surface the closest to the ground; both the upper sole component and the lower sole component are resin EVA (ethylene-vinyl acetate) injection molding components; the upper sole component and the lower sole component are integrally formed into a midsole; the midsole has a plurality of closed cells, each cell receives gas having the pressure greater than or equal to one standard atmospheric pressure; the closed cells are positioned in the area of the first distal phalanxes to first metatarsal bones and second middle phalanxes, the area of the forefoot metatarsal bones and the heel calcaneal area. The sole provided herein can provide effective cushioning and elasticity, has low cost and light weight and has better user experience.

Description

technical field [0001] The invention relates to the technical field of footwear products, in particular to a sports shoe sole, its preparation method and application. Background technique [0002] Shoes have a long history of development. Footwear production is an important industry in my country's light industry and an integral part of the clothing industry. There are many ways to classify shoes according to the object of use, production process and purpose. Among them, sports shoes refer to the shoes that people wear when performing sports. The broad concept is specifically: the training process of appropriate sports, fitness sports, leisure sports, recreational sports and professional competitive sports and the shoes used in official competitions. kind. [0003] The research of sports science experiments shows that according to the needs of biomechanics, sports shoes normally need to meet the three characteristics requirements of providing shock absorption, maintaining ...
