Problems solved by technology

[0002] In order to increase the wear resistance of shoes, the outsole of shoes is generally made of rubber material. In order to increase the comfort and elasticity of shoes, the middle and bottom of shoes are generally made of softer EVA material. Difficult. At present, the processing method generally adopts manual methods. First, roughen the bonding surface of the artificial outsole and midsole shoe materials, and then apply a treatment agent on the bonding surface of the sole, and glue them together. The entire production process requires A large number of manual operations, low production efficiency, high labor costs, and in the process of gluing and gluing, the glue will emit a pungent smell, which will pose a greater threat to human health
And this kind of artificial gluing method is not firm enough, and it is easy to cause degumming.

Embodiment Construction

[0011] The present invention will be described in further detail below in combination with specific embodiments.

[0012] A kind of shoe sole processing technology of integrated molding provided by the present invention, its processing technology comprises the manufacturing technology of the outsole of wear-resistant rubber material, the manufacturing technology of elastic EVA midsole, and the manufacturing technology of outsole is as follows: the preparation of rubber material is sent Enter the wheel table, cut the stock according to the shape of the sole, and use hydraulic molding to make the prototype of the outsole. The optimum heating temperature of the machine is 150-160°C, and the optimum value of molding pressure is 150-160KG / CM 2 , and the outsole prototype is trimmed; the EVA midsole production process cuts the EVA raw material to make a midsole in the shape of the shoe body; the processing process also includes the following process, mixing the EVA material and the r...

Abstract

The invention relates to a one-piece formed sole processing process, in particular to a processing process for forming sole sand insoles. The processing process comprises: performing a manufacturing process of wear-resistance rubber material soles; performing a manufacturing process of elastic ethylene vinyl acetate (EVA) insoles; mixing the EVA material and rubber material in a certain ratio, wherein the content of EVA is 30 to 40 percent; forming shoe-shaped cover pieces; placing the cover pieces on the soles; placing the insoles made by the EVA manufacturing process on the cover pieces; and performing thermocompression of the soles and the insoles by heating a template and applying die compression, wherein the heating temperature is 150 to 165 DEG C, and the applied die pressure is 70 to 80KG / CM2. Because the cover pieces made of the mixed material, after undergoing thermocompression with the soles and insoles, have a very big adhering force, the soles and the insoles are combined, the separating phenomenon is eliminated, lots of labor cost can be saved in a production process, the dangers caused by the conventional production process to the health of human body are eliminated, and the production environment of the plant is improved.
