Blind holes should be opened through holes as much as possible, and process holes can be opened when necessary. In order to prevent heat treatment deformation and cracking, the cross-section size should be uniform, symmetrical and simple. In addition, pay attention to the deformation and cracking of the subsequent heat treatment due to the unreasonable structural design. It is easy to cause premature failure of the mold.
The stress concentration caused by sharply rounded corners can be as high as 10 times the average stress. It should be emphasized that the structural design of the mold should try to avoid sharp corners and excessive cross-sectional changes.

The mold design manual describes in detail the issues that should be paid attention to in the design of aluminum die-casting molds. Structural Design of Aluminum Die Casting Mold Therefore, the requirements for aluminum mold materials are relatively high.Īluminum die casting telecom housing mold 2. After thousands of die castings, defects such as cracks appeared on the surface of the mold. When the mold is opened, the surface of the cavity bears great compressive stress. Without preheating the mold, the surface temperature of the cavity will rise from room temperature to the temperature of the liquid, and the surface of the cavity will endure great tensile stress. aluminum die casting manufacturer The melting point of aluminum is 580-740☌, and the temperature of the molten aluminum is controlled at 650-720☌ during die casting. Aluminum die casting molds are hot work molds, and their use conditions are extremely harsh. According to statistics, due to improper material selection and heat treatment, the early failure of the mold accounts for about 70%. The impact of mold materials on mold life is reflected in three aspects: whether the selection of mold materials is correct, whether the materials are good, and whether the use is reasonable.
