Description

Technical Field

[0001] The utility model relates to the technical field of hot pressing structures, in particular to a heating and cooling device for hot pressing equipment. Background Art

[0002] Thermoforming is a simple and common processing method in the plastic processing industry. It mainly uses the heating of the processing mold, adding the sample, fixing the model on the heating plate with pressure, controlling the melting temperature and time of the sample to achieve hardening and cooling after melting, and then taking out the finished model.

[0003] The hot pressing equipment used in hot pressing molding needs to prevent the heat from the heating plate from being transferred to the hot pressing equipment. Because there is an oil pressure seal inside the hot pressing equipment, excessive temperature will cause the seal to soften and leak oil. Therefore, it is generally necessary to set an insulation board between the heating plate and the workbench of the hot pressing equipment. However, such a structural setting cannot effectively control the temperature of the heating plate. Utility Model Content

[0004] The purpose of the utility model is to provide a heating and cooling device for hot pressing equipment to solve the problems raised in the above background technology.
