During the molding process of die-casting parts, why is it necessary to use a die-casting mold temperature controller to control the die-casting mold temperature? What is the purpose of controlling the temperature of the die casting mold? The function of Ouneng die-casting mold temperature controller is mainly reflected in two aspects:

First, the use of die-casting mold temperature controller can improve the quality of die-casting parts. In die-casting of alloys, mold temperature is a key factor affecting the quality of die-casting parts. Before die-casting begins, a die-casting mold temperature machine needs to be used to preheat the mold. Different die-casting alloy materials have different requirements for the surface temperature of the mold. For example, zinc alloy is generally 170-220°C; aluminum alloy is 220~260 degrees.

Under the premise that the injection parameters are the same and the alloy liquid can fill the cavity, the lower the mold temperature, the faster the cooling rate of the alloy. Especially in the die-casting process, as the number of injections increases, the die-casting temperature will continue to rise, and the temperature difference between the inside and the surface of the die-casting will continue to decrease, making the cooling rate of the alloy slower and slower during die-casting, resulting in poor density of the metal structure of the casting. , or even pinholes or larger shrinkage cavities may appear in the casting, seriously affecting the quality of the casting. It can be seen that only when the die-casting molding surface can be maintained within the required temperature range during the die-casting process, can high-quality castings be obtained.

2. The use of die-casting mold temperature controller can extend the life of the die-casting mold. During the die-casting molding process, if there is no die-casting mold temperature controller for cooling, the mold temperature will get higher and higher as the number of die-casting moldings increases, and the thermal stress will increase. The impact stress of the high-speed injection of the die-casting machine will cause cracks in the mold soon. The use of a die-casting mold temperature controller with a cooling system can keep the mold temperature within a certain range, thereby keeping the mold in a good state of high hardness and in a good thermal balance, so the service life of the mold can be extended.
