The mold temperature machine is also called the mold temperature control machine. It was originally used in the temperature control industry of injection molds. Later, as the development of the machinery industry became more and more widely used, the temperature of the mold temperature controller is generally divided into water temperature and oil temperature controllers, which can reach plus or minus 0.1 degrees.
There is also a lot of room for the application of the mold temperature machine in the die casting industry. Especially in the manufacture of magnesium alloys and aluminum alloys, uneven or inappropriate mold temperatures can lead to instability in the dimensions of the castings, and ejection of the castings during the production process Defects such as thermal pressure, mold sticking, surface depression, shrinkage holes, and thermal bubbles. The mold temperature machine also affects the production cycle, such as the filling time, cooling time and spraying time all produce unstable variables. The life of the mold will also cause thermal cracking of expensive steel due to the impact of overcooling and overheating, which accelerates its aging.
The use of temperature controllers in other industries is an inevitable condition for equipment composition, and is called differently. The mold temperature machine is called an oil heater in the temperature control of the PVC sheet roller, the mold temperature machine is called a temperature control device in the extruder equipment, and the mold temperature machine is called a temperature control system or a temperature controller in a rubber mixer equipment These devices are basically a process of rapid heating first and then thermal insulation. After heating up in rubber equipment, it is necessary to perform a cooling process for a long time.
The design of the refrigerating circuit of the mold temperature controller and its components are important to the precise control of the mold temperature. When the temperature of the mold or the heating liquid rises to the set value, the mold temperature controller must be able to quickly and effectively prevent the temperature from continuing to rise. The method is to introduce another lower temperature liquid. The solenoid valve is responsible. Therefore, the elimination and stability of the mold temperature overshoot depends on the size of the solenoid valve.
