1. According to the structure of the casting, the different temperatures of different parts of the mold are controlled through several independent cooling water circulation systems, thereby providing the conditions for sequential solidification of the casting; the most sensitive and suitable position can also be selected in each cooling circuit of the mold , install a thermal sensor to scan and monitor the temperature, and then operate the opening and closing of the electric valve in the input section through an adjustable controller, although this method is good, but the investment is large, especially the cost of the thermal sensor and its circuit, It is usually only used to produce die castings with larger dimensions and higher requirements.

2. The temperature of the mold is controlled by the automatic heating and cooling device of the heat transfer oil and the special mold temperature machine for die-casting. Controlling moving and stationary molds within a certain temperature range is much better than simply cooling the mold. Through the heating and cooling efficiency and circulation speed of the heat transfer oil, the microcomputer PID adjusts and controls the oil temperature.
The cooling water temperature of the die-casting mold should not be too high, otherwise the steam pressure formed when the water boils will affect the cooling effect. The upper limit of the cooling water temperature is 95°C, and the lower limit is 10°C. The water cooling hose connected to the mold should not be broken, and the cooling water should be softened by ion exchange, otherwise the water will gradually produce scale on the inner wall of the cooling channel, white Deposits will make cooling less effective.
