When the temperature of the plastic injection mold is controlled, it cannot be heated quickly. In order to improve the above-mentioned disadvantages, the patent with application number 202221773772.5 in the public technology is applied, including a heat spreader, the top wall of the heat spreader is symmetrically provided with two installation grooves, and the center position of the side wall of one side of the heat spreader is provided Although the groove can be used to heat the plastic injection mold through the heater on the heat spreader, its temperature sensor can perform accurate and fast temperature sensing work, and a heater is fixedly installed in the installation groove. When the temperature of the plastic injection mold is controlled, it can be heated quickly, but the device still has certain disadvantages in actual use. For example, the heat generated by the operation of the heater has a relatively general effect on the thermal conductivity uniformity of the heat spreader, and there is a temperature difference on the heating surface of the heat spreader. The temperature control accuracy of the injection mold needs to be improved, and the heat generated after the heater is operated is exported to the outside in large quantities, and the energy utilization rate is low.
