Technical Field

[0001] This utility model relates to the field of hot pressing mold annealing and cooling technology, specifically a hot pressing mold annealing and cooling device. Background Technology

[0002] Hot pressing is a simple and common processing method in the non-metallic processing industry. The process mainly involves heating the mold and the product, softening or melting the product placed in the hot pressing mold, and using the weight of the mold itself as the pressure for product forming. After the hot pressing mold and the product go through the annealing and cooling process, the product in the mold cavity will gradually cool and harden, and finally the molded product can be removed. Annealing and cooling equipment is usually used.
