Aluminum alloy die-casting special mold temperature machine

Aluminum alloy die-casting special mold temperature machine is used to heat the magnesium aluminum alloy to an appropriate temperature before manufacturing, so that it meets the production process requirements for die-casting. To prevent damage or deformation to the die-casting parts caused by excessively high or low temperature, the temperature is controlled to keep it within the temperature required by the production process. Finally, the die-casting parts are slowly cooled to improve the forming rate of the die-casting parts.

Finally, the die-casting parts are slowly cooled to improve the forming rate of the die-casting parts.

In the manufacturing of aluminum alloys, uneven or inappropriate mold temperatures can lead to dimensional instability of the die-casting special mold temperature machine, causing deformation of the castings during the production process, resulting in defects such as thermal pressure, mold sticking, surface indentation, internal shrinkage porosity, and hot bubbles. This requires the use of an aluminum alloy die-casting mold temperature machine. Die casting involves injecting high-temperature molten metal into the die casting cavity, followed by cooling and forming, resulting in complete die cast products. During this process, there is a significant temperature change in the die-casting mold, which requires temperature control through external equipment. The temperature control of the die-casting mold varies at different stages and has different requirements. If the temperature is too low during preheating, the metal melt will solidify prematurely and the number of defective products will increase.

The die-casting mold temperature machine can keep the magnesium alloy die-casting mold within the temperature range required by the die-casting process, ensuring that the magnesium alloy liquid fills the die-casting cavity according to the design requirements, resulting in a smooth surface, clear contour, and qualified internal quality die-casting parts. The heating and cooling system of the magnesium alloy die-casting mold temperature machine is controlled by dual PID, using automatic control. The temperature sensor detects the oil temperature or mold temperature. If the temperature is lower than the set value, the control system will turn on the heating element to heat the heat transfer oil; If the temperature is higher than the set value, the control system will turn on the cooling element to cool the heat transfer oil.

Generally, before die-casting, the surface of the mold is preheated to a certain temperature before die-casting. When the temperature reaches a certain height, in order to prevent excessive temperature and damage to the appearance of the die-casting, temperature control is necessary.

If the temperature control of the die-casting mold is too low, it will make the internal structure of the entire casting relatively loose. During the process of die-casting, as the number of injections increases, the temperature of the die-casting mold will gradually rise. At this point, it is necessary to effectively control the temperature of the mold. If the temperature of the die-casting mold continues to rise, it will cause the die-casting metal to stick to the mold, increasing the difficulty of unloading. At the same time, excessively high die-casting temperatures can cause the mold body to expand, thereby affecting accuracy. Only by controlling the temperature within a reasonable range can the success rate of the entire die-casting process be better ensured. It mainly refers to three aspects: material melting temperature, mold temperature during injection, and melt temperature.
