　　Ensure that the aluminum alloy die casting mold does not deform

　　In the production of aluminum alloy die casting, due to the emergence of new processes, to solve many complex mold processing and heat treatment deformation problems, but because the development of new processes is not yet mature, there are still a variety of problems, therefore, the problem of heat treatment is still there.

　　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.

　　1 Factory Building

　　The heat treatment of aluminum alloy die casting die is generally placed in the last stage, heat treatment must be done, not only to maintain the performance requirements of the die but also to avoid the situation of out-of-tolerance deformation, for the heat treatment of the die casting die also has a certain experience, can ensure the quality of the die casting die, and then produce high-quality die casting parts.
