油温机由水箱、加热冷却系统、动力传输系统、液位控制系统以及温度传感器、注入口等器件组成。通常情况下，动力传输系统中的泵使热流体从装有内置加热器和冷却器的水箱中到达模具，再从模具回到水箱；温度传感器测量热流体的温度并把数据传送到控制部分的控制器；控制器调节热流体的温度，从而间接调节模具的温度。如果模温机在生产中，模具的温度超过控制器的设定值，控制器就会打开电磁阀接通进水管，直到热流液的温度，即模具的温度回到设定值。如果模具温度低于设定值，控制器就会打开加热器。 The 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
