1) water-carrying mold temperature machine
2) Oil conveying mold temperature machine
Working principle:
The mold temperature machine consists of water tank, heating and cooling system, power transmission system, liquid level control system, temperature sensor, injection port and other devices. Usually, the pump in the power transmission system makes the hot fluid reach the mold from the water tank with 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, thereby indirectly adjusting the temperature of the mold. In the production process of the mold temperature machine, if the mold temperature exceeds the set value of the controller, 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 mold, returns to the set value. If the mold temperature is lower than the set value, the controller will turn on the heater.
