Embodiment 2

[0040] Present embodiment 2 provides a kind of production technology of sole, comprises following manufacturing steps:

[0041] (1) 50 parts of EVA, 30 parts of rubber and 30 parts of elastomer are obtained by injection molding according to parts by weight, and the foamed material of EVA is used as the shock-absorbing sheet;

[0042] (1) Put the wear-resistant anti-slip sheet into the forming die groove so that it is attached to the bottom and side walls of the forming die groove;

[0043] (2) Putting a shock absorbing sheet on the above-mentioned wear-resistant anti-slip sheet, so that the described shock-absorbing sheet is directly above the wear-resistant anti-slip sheet;

[0044] (3) Set the hot-pressing temperature to 118°C, the hot-pressing pressure to 430KPa, and the hot-pressing time to 65s, close the molds, perform in-mould hot-pressing molding, and make the wear-resistant anti-slip sheet fit the shock-absorbing sheet through hot-pressing Wrapping from the bottom of th...

Embodiment 3

[0048] Present embodiment 3 provides the production technology of another kind of sole, comprises following manufacturing steps:

[0049] (1) 55 parts of EVA, 17 parts of rubber and 17 parts of elastomer are obtained by hot pressing according to the number of parts to obtain the wear-resistant anti-skid sheet, and the foamed material of EVA is used as the shock-absorbing sheet;

[0050] (1) Put the wear-resistant anti-slip sheet into the forming die groove so that it is attached to the bottom and side walls of the forming die groove;

[0051] (2) Putting a shock absorbing sheet on the above-mentioned wear-resistant anti-slip sheet, so that the described shock-absorbing sheet is directly above the wear-resistant anti-slip sheet;

[0052] (3) Set the hot-pressing temperature to 115°C, the hot-pressing pressure to 450KPa, and the hot-pressing time to 68s, close the molds, perform in-mould hot-pressing molding, and make the wear-resistant anti-slip sheet fit the shock-absorbing sh...

Abstract

The invention provides a shoe sole and a production process thereof, and relates to the field of shoe sole structures. The shoe sole structurally comprises a shoe outer layer and a shock absorption layer, wherein the material components of the shock absorption layer are the same as or partially the same as those of the shoe outer layer, and the shock absorption layer and the shoe outer layer are compounded through hot pressing; the shoe outer layer is formed by hot-pressing the same sheet and comprises a bottom outer layer located at the bottom of the shoe and side edge layers located on the side edges of the shoe; and the bottom and the side edges of the shock absorption layer are wrapped in the bottom outer layer and the side edge layers of the shoe outer layer respectively. The invention also provides the production process of the shoe sole. In the process, an EVA foaming material is used as a shock absorption sheet in the process, a material of a wear-resistant anti-slip sheet contains an EVA material component, and the two materials both contain EVA; EVA structures are the same and have compatibility, so that the two materials are attached and formed under the hot pressing effect of a mold, so that the wear-resistant anti-slip sheet and the shock absorption sheet are tightly and fixedly attached and connected.

Description

technical field [0001] The invention relates to the field of shoe sole structures, in particular to a shoe sole and a production process thereof. Background technique [0002] As an important part of shoes, the sole should have many characteristics such as wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, and easy to fit the foot shape; the main structure of the sole is divided into the outer layer of the shoe and the shock-absorbing layer , inner sole and heel and other structures; the outer layer of the shoe refers to the outermost layer of the sole, and the outer layer of the shoe mainly ensures the super wear resistance of the sole, which is a necessary condition for the durability of the sole. In addition to the wear-resistant function, the main function that must also be anti-skid; the main function of the shock-absorbing layer is to achieve shock absorption during walking; [0003] Rubber is o...
