Abstract: A method of automatedly heating, press molding and replacing multiple molds for insole materials contains steps of: setting manufacture parameters by using a host control unit; setting a size and quantity of multiple insoles, a reloading weight of each mold, a heating temperature and a molding time of each insole in each mold; feeding the insole materials into the multiple molds by using the automatic material feeder to be heated and press molded; judging whether the molding time of each mold is more than or equal to a set time; waiting the molding time when the molding time of each mold is not more than or equal to the set time; taking the multiple insoles out of the multiple molds and judging whether the multiple insoles reach a set production quantity, and stopping production of the multiple insoles, when the insoles reach the set production quantity, thereby obtaining automatically production.

Abstract: A recycling method includes providing an EVA insole residual product including an EVA foam material, a film, and a cloth material, placing the EVA insole residual product into an oven, heating the EVA insole residual product to a temperature of 130±25° C., and detaching the cloth material from the EVA foam material. The film includes an EVA, and a tackifier. The EVA of the film has a mass proportion of 85-95%. The tackifier has a mass proportion of 5-15%. An antioxidant is appended into the film and has a mass proportion of 0.1% of the total mass of the EVA and the tackifier. After the cloth material is detached from the EVA foam material, the EVA foam material and the film are crushed and kneaded and are recycled.
