he mould temperature machine is composed of water tank, heating and cooling system, power transmission system, liquid level control system, temperature sensor, injection port and other devices. In general, the pump in the power transmission system enables the hot fluid to arrive at the mold from the water tank equipped with the built-in heater and cooler, and then return to the water tank from the mold; the temperature sensor measures the temperature of the hot fluid and transmits the data to the controller of the control part; the controller adjusts the temperature of the hot fluid body, so as to indirectly adjust the temperature of the mold. If the temperature of the mould exceeds the set value of the controller during the production of the mould temperature machine, the controller will open the solenoid valve to connect the water inlet pipe until the temperature of the hot fluid, that is, the temperature of the mould returns to the set value. If the mold temperature is lower than the set value, the controller will turn on the heater.
