Description

Technical Field

[0001] The utility model relates to the field of blowing materials for silicone hot-pressing molding molds, in particular to a quick-install residual material blowing device for silicone hot-pressing molding. Background Art

[0002] Hot pressing is a simple and common processing method in the plastic processing industry. It mainly uses the heating process of the mold, injects the sample, fixes the model on the heating plate with pressure, controls the melting temperature and time of the sample, so that it can harden and cool after melting, and then take out the finished model. After the hot pressing of the silicone block, the residual silicone block in the mold needs to be removed to facilitate the normal molding of the subsequent silicone block.
