Aluminum Die Casting Parts Tooling
1. According to the structure of the casting, the different temperatures of different parts of the mold are controlled by several independent cooling water circulation systems, so as to provide the conditions for sequential solidification of the casting; it is also possible to select the most sensitive and most suitable position 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, 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. It is much better to keep moving and stationary molds within a certain temperature range than simply cooling them. Die casting mold temperature machines use heat transfer oil as the medium, which is the working fluid leading to the mold. Through the heating and cooling efficiency of the heat transfer oil and the circulation speed, the microcomputer PID adjusts and controls the oil temperature.
The cooling water temperature of Aluminum Die Casting Parts Tooling 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℃, the lower limit is 10℃, the water cooling hose connected to the mold should not be broken, and the cooling water should be softened by ion exchange method, otherwise the water will gradually produce scale on the inner wall of the cooling channel, white Precipitates make cooling less effective.
Due to the high temperature of the die-casting mold core surrounded by the alloy liquid, it is easy to form a sticky mold in production, and due to the rapid increase in temperature, the local hardness of the mold core is reduced, resulting in dimensional deviation. The casting core temperature is too high to easily cause pores and shrinkage; Excessive temperature of the active core and slider will shorten slider and guide life.
In order to avoid the above-mentioned defects, for the core with small diameter, a mold core jet cooler with fine hole cooling has been developed abroad. Even if the core temperature of Aluminum Die Casting Parts Tooling is 200°C, a special piston pump is used to maintain the drainage capacity at a pressure of more than 1 MPa, a large amount of cooling water is injected and the drainage is stopped immediately. , the high pressure air flow can fill the cooling circuit to drain the residual cooling water. The device not only improves the service life of the core, but also improves the quality of the die casting.
The temperature control of Aluminum Die Casting Parts Tooling is one of the important parameters in the die casting process, which directly affects the quality and economic benefits of die casting. Fully understanding the role of die-casting temperature control and various factors affecting die-casting temperature, and bringing the application of die-casting heat balance calculation into production is an indispensable condition for realizing the scientific level of die-casting production.
