Technical Field
[0001] The utility model relates to the technical field of injection molding equipment, in particular to a water-cooling shaping device for EVA shoes. Background Art
[0002] EVA shoes refer to slippers or sandals made of EVA material, which are loved by most people for their softness and comfort. After the EVA shoes are injected and molded, they will expand rapidly. At this time, the temperature of the EVA shoes is high, and their shape is unstable and easily deformed. A shaping mold needs to be inserted into the shoe body for support and shaping. The current cooling method for EVA shoes is to insert the shoe body that has just been injected into the shaping mold and wait for the shoe body to cool and shape naturally. The cooling and shaping time is long, which not only requires more shaping molds, but also limits the processing efficiency of EVA shoes. Utility Model Content
