Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a vacuum plastic suction molding mold for a plastic sheet composite material. Background Art

[0002] Blister mold refers to the mold used in blister production. The main principle is to fix thermoplastic plastic plates and sheets on the mold, heat them with a radiation heater to reach the softening temperature, and then use a vacuum pump to remove the air between the mold and the plate, so that the plate blank is formed according to the mold contour. However, after the production of the blister mold is completed, the product cannot be taken out quickly, and rapid demoulding cannot be achieved. It is not suitable for the processing of blister products with high quality requirements.
