Shoe body manufacturing process

Abstract

The invention relates to the technical field of shoe body production, and discloses a shoe body manufacturing process. The shoe body manufacturing process involves a shoe body, wherein the shoe body comprises a rubber material, a fabric and a coating; and the rubber material comprises the following raw materials of, in parts by weight, 50 parts of chloroprene rubber, 5-10 parts of butadiene rubber, 5 parts of carbon masterbatch, 20-40 parts of white carbon black, 2 parts of a white carbon black active agent, 1-2 parts of oil, 5 parts of zinc oxide, 2 parts of an adhesive, 2 parts of a coupling agent, 4 parts of magnesium oxide and 10 parts of coumarone resin, the fabric comprises 50 parts of superfine fibers, and the coating comprises 5 parts of activated carbon powder, 5 parts of waterproof coating and 5 parts of rubber deodorant powder. One maximum temperature value is set on an automatic temperature detector, when the detected temperature exceeds the maximum value, dry ice spraying devices arranged on the periphery of a mold spray dry ice to corresponding molds, heat around the molds is taken away through sublimation of the dry ice, therefore the temperature of the molds is controlled, the effect of rapid cooling forming of a shoe sole is achieved, and meanwhile, quick demolding is facilitated.

Description

technical field [0001] The invention relates to the technical field of shoe body production, in particular to a shoe body manufacturing process. Background technique [0002] The preparation materials for shoe soles generally include rubber, plastic, rubber-plastic composite materials, etc., and the molding methods include compression molding, injection molding, etc. Among them, injection molding is suitable for the preparation of thermoplastic soles or thermoplastic elastomer soles, with high production efficiency and high product quality. The post-processing workload is small and the processing adaptability is strong. The mold for shoe sole injection molding is generally installed on the injection molding machine, usually including the corresponding punch and die. After the two molds are closed, the raw materials are injected into the mold, and the molded product is taken out after the mold is opened. .

Problems solved by technology

[0003] The injection molding time refers to the time required for the plastic melt to fill the cavity, excluding auxiliary time such as mold opening and closing. Although the injection molding time is very short, it has little impact on the molding cycle, but the adjustment of the injection molding time has a great impact on the gate, flow, etc. The pressure control of the channel and the cavity has a great effect. A reasonable injection time is helpful for the ideal filling of the melt, and it is very important for improving the surface quality of the product and reducing the dimensional tolerance. The injection time is much lower than the cooling time. The time is about 1 / 10 to 1 / 15 of the cooling time. This rule can be used as the basis for predicting the entire molding time of plastic parts. Demolding is the last link in an injection molding cycle. The mold still has a very important impact on the quality of the product. Improper demolding methods may lead to uneven force on the product during demoulding, and defects such as product deformation when ejected.

[0004] The rapid injection molding manufacturing mainly uses the additive material molding process. The additive material molding is also called the accumulation molding. After the mould, due to the rise of the mold temperature, it is often difficult to separate the molded sole body from the mold, and because the melt temperature is too high, the cooling molding speed is slow and the production efficiency is affected. Therefore, we propose a shoe body production process
