Then, the resin mixture prepared in the first step is impregnated on the glass fiber cloth by using the pre-impregnated glass fiber cloth, and the glass fiber cloth is cut, and the pre-impregnated glass fiber cloth is cut according to the preset semi-inserted midsole or midsole shape for later use. Then hot-pressing forming, putting the glass fiber cloth cut in the third step into a preheated mold, and hot-pressing the glass fiber cloth cut in the third step to obtain a shoe midsole product. The technology also provides a midsole manufactured according to the manufacturing method and a shoe containing the midsole.
A sole forming die is arranged, a cavity fixing position is arranged on the sole forming die for forming soles with the same size, latex is attached to the upper surface of the fiber intermediate layer, and a fiberboard component attached with latex is placed on the cavity fixing position.
An injection hole is arranged on the sole forming mold, and the mold cavity is communicated with the injection molding machine through the injection hole, and the injection molding machine injects polypropylene material into the mold cavity through the injection hole, and the polypropylene material is bonded with the bottom surface of the fiber midsole to form the midsole.
The technology also provides a shoe midsole molding die and a shoe midsole structure. Compared with the traditional midsole, this technology can reduce the labor cost by more than 3 times. At the same time, because the size of the molded sole is accurate, the cost control of production materials can be reduced and the yield of sole products can be improved. The mold control of the new midsole can ensure the smooth and beautiful lines, radians and hypotenuse, and increase the aesthetics of products.
