Heating water type mold heater for PU foam production
Introduction of mold temperature control machine
Mold temperature machine, also known as mold temperature control machine, is widely used in plastic molding, die-casting, rubber tires, rollers, chemical reactors, bonding, banburying and other industries. The mold temperature machine is generally divided into a water temperature machine and an oil temperature machine, and the temperature control accuracy can reach ±0.1 °C.
working principle
The mold 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. Typically, a pump in the power transmission system moves the hot fluid from a tank with built-in heaters and coolers to the mold and from the mold back to the tank; a temperature sensor measures the temperature of the hot fluid and transmits the data to the control section. The controller; the controller regulates the temperature of the hot fluid, thereby indirectly regulating the temperature of the mold. If the mold temperature machine is in production and the mold temperature exceeds the set value of the controller, the controller will open the solenoid valve and 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.
Features of water transport mold temperature machine
1. The maximum operating temperature is 40℃-180℃, and the temperature control accuracy is ±1℃;
2. Microcomputer touch control is easy to operate;
3. Automatic exhaust after startup;
4. Display of water outlet and return water temperature;
5. Mold backwater function (optional);
6. Stainless steel pipelines, reduce tube yin and rust;
7. Fault display, maintenance does not require professionals.
