Aluminum Die Casting Dies is a kind of mold that is commonly used at this stage. It has the characteristics of long manufacturing time, large project investment, and high precision. Therefore, the product cost of this mold is also high. Aluminum Die Casting Dies is a tool for forging metal material parts. It is a tool for the whole process of aluminum die casting on a special forging aluminum die casting machine. However, due to the hazards of a series of external environmental factors such as raw materials and production processes, Aluminum Die Casting Dies will become invalid and damaged too early. Let's take a look at what are the reasons that affect the service life of Aluminum Die Casting Dies?

1. Material

The choice of Aluminum Die Casting Dies material has a great influence on the service life of the mold. According to data research, improper material selection and heat treatment will cause early failure of the mold, while Aluminum Die Casting Dies is a hot work mold. Its production and manufacturing conditions are relatively harsh. The melting point of aluminum is between 580-740°C, so in die casting At this time, the production personnel should control the temperature of the molten aluminum between 650-720℃ and preheat it. If it is not preheated, the temperature of the mold cavity surface will rise from room temperature to the liquid temperature. At this time, the cavity surface will be Withstand greater tensile stress. During the mold opening process, the surface of the cavity will also be subjected to great compressive stress, and after thousands of die castings, defects such as cracks will appear on the surface of Aluminum Die Casting Dies.

2. Structural design

When designing Aluminum Die Casting Dies, avoid too sharp rounded corners and excessive cross-sectional changes, because the stress concentration caused by sharp rounded corners is 10 times the average stress of the mold, which can easily lead to early failure of the mold. In addition, designers should also pay attention to the deformation and cracking of Aluminum Die Casting Dies in the subsequent heat treatment. In order to prevent the formation of the above defects, the cross-sectional dimensions of the mold should be uniform and symmetrical. The blind holes should be opened as through holes as much as possible, and process holes can be opened if necessary. . Aluminum Die Casting Dies should also avoid the appearance of geometric gaps in the structural design of Aluminum Die Casting Dies, including knife marks, included angles, scouring grooves, cavities and cross-sectional mutations.

3. Machining

Incorrect machining may easily cause stress concentration and insufficient finish, which may cause defects in Aluminum Die Casting Dies and affect the service life. Therefore, during the processing of Aluminum Die Casting Dies, the surface of the cooling control system should be smooth with no traces of machining.

The above are the three major factors that affect the service life of Aluminum Die Casting Dies. With the advancement of science and technology, manufacturers need to learn advanced machining technology, pay attention to production precautions, and try to improve the processing accuracy of Aluminum Die Casting Dies, thereby extending the mold.
