Description

Technical Field

[0001] The utility model relates to the field of foam shoe manufacturing equipment, in particular to a foam shoe secondary foaming molding machine. Background Art

[0002] EVA soles refer to soles made of EVA materials. The material used for EVA soles is ethylene / vinyl acetate copolymer, also known as ethylene-vinyl acetate copolymer, which is made by copolymerization of ethylene E and vinyl acetate VA. The sole foaming machine is a very common equipment used to manufacture soles in shoe production lines.

[0003] For example, the patent document with the announcement number CN204136304U discloses an automatic shoe material secondary foaming molding machine, which includes a frame, a clamping mechanism, a sliding mechanism, a mold and a heating and cooling mechanism. The lower mold slides horizontally driven by the sliding cylinder, and the upper mold moves up and down driven by the opening and closing cylinder. The booster cylinder pressurizes the upper mold.
