Abstract

The invention provides a mould temperature control device and a control method thereof; wherein, the control device comprises a driving circuit of an ice water valve, a driving circuit of a triple valve and a temperature judgment circuit; wherein, the temperature judgment circuit can judge the mould temperature of the injection molding machine. The mould temperature control device is characterized in that when the temperature reaches the first design temperature, the control circuit of the triple valve drives the triple valve to move, stops the circulating hot fluid from flowing to the mould of the injection molding machine and controls the driving circuit of the ice water valve to drive the movement of the ice water valve; when the temperature reaches the second design temperature, the temperature judgment circuit can control the driving circuit of the triple valve to drive the movement of the triple valve, control the circulating hot fluid to the mould of the injection molding machine and control the driving circuit of the ice water valve to stop the movement of the ice water valve.

Description

technical field [0001] The invention provides a mold temperature control device and a control method thereof, especially a control device and a control method capable of rapidly heating and cooling the mold temperature before and after injection molding. Background technique [0002] In the injection process of the injection molding machine, when the mold temperature is low, the injected molten resin contacts the mold without its temperature rising, so the surface of the resin solidifies rapidly and the surface of the molded product becomes rough. Therefore, the copying of the cavity surface of the mold may be insufficient. In order to avoid this situation, on the one hand, it is necessary to increase the temperature of the mold and delay the solidification of the surface of the molten resin; on the other hand, after the molten resin is filled in the mold, it is best to immediately lower the mold temperature to shorten the cycle of the injection process. [0003] Therefore,...
