[0002] Molds are various molds and tools used in industrial production to obtain the required products by methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. Hot pressing is a simple and common processing method in the plastic processing industry. It mainly uses heating to process the mold, inject the sample, fix the model on the heating plate with pressure, control the melting temperature and time of the sample, so as to achieve hardening and cooling after melting, and then take out the finished model.

[0003] However, for a molding mold without an ejection structure, some materials will adhere to the inner wall of the lower mold base after molding, making it difficult to remove the materials. In addition, the natural cooling of the materials after molding will reduce the production efficiency of the equipment. Therefore, a hot pressing molding mold is proposed. Utility Model Content
