Description

Technical Field

[0002] During the plastic molding process, the mold needs to be kept at a constant temperature so that the plastic can be pressed into the desired shape. When the mold is inspected and repaired, the mold needs to be cooled down quickly. For this reason, a fluid channel is usually provided inside the mold. The temperature of the water flowing through the mold is adjusted by the mold temperature controller to control the temperature of the mold and realize the plastic pressing and molding. The control system of the water-cooled mold temperature controller consists of a PC control board (or controller), an air switch, a contactor, an overload protector and a relay, etc., and the piping system of the water-cooled mold temperature controller consists of a heater, a water pump, a pressure gauge, a thermocouple, a liquid level sensor, a valve, a pipe, etc. The heater provides heat energy, and the circulating pump provides Power supply, because the heater in the water-cooled mold temperature controller generates high-temperature heat, and the temperature range of the electrical components of the control system is about minus five degrees to forty-five degrees, if the ambient temperature is too high, it will cause temperature over-limit and failure, and the stability of the electronic circuit will decrease. The existing water-cooled mold temperature controller assembles all the components of the control system and the piping system in the same chassis. The heat generated by the heater in the chassis will diffuse and heat up, so that the control system will be in a high-temperature environment for a long time. It has the problem of temperature over-limit and failure, reduced stability and affecting the service life. Therefore, a new water-cooled mold temperature controller is designed to change the above technical defects. Utility Model Content
