　　Ensure that the aluminum alloy die casting mold does not deform

　　First, heat treatment affects die steel

　　The original structure and chemical composition of the die steel will be affected by heat treatment, for the die steel, the main consideration is the carbide segregation, the shape and distribution of the carbide, different carbide distribution on the expansion and contraction of the matrix is also different, so it will also affect the deformation after heat treatment.

　　Second, prevent the deformation of die casting mold

　　In order to prevent the deformation of die casting mold, it is necessary to improve the mold design, avoid the mold structure with a wide cross-section size as much as possible, and strive for symmetry of the mold structure.
