[0002] The fully automatic vacuum secondary midsole molding machine integrates multiple functions, including heating, cooling, and vacuum treatment, and can automatically complete the molding process of the shoe midsole. A common process for making shoe midsoles is to use granular EVA (ethylene-vinyl acetate copolymer) material and heat and foam it through a mold. During the process, the granular EVA material is evenly filled into the mold cavity of the lower mold. The upper mold is pressed down and tightly closed with the lower mold while the mold is heated. After the EVA material is completely foamed and cooled, the mold is opened and the shoe midsole is removed, completing the processing of the shoe midsole. However, the existing shoe midsole processing process often requires manual operation during mold closing, which is inefficient. Manual mold closing can easily cause mold deflection, affecting the processing quality of the sole.
