Die casting is one of the main forming methods of aluminum alloy parts. However, the defects such as surface rheology, micro-shrinkage and porosity, which may exist in die casting parts, must be eliminated by surface grinding, painting and repairing in order to ensure the surface quality requirements of the products. The quality of aluminium alloy die castings is mainly determined by the design and manufacture of dies used in die casting and the technological conditions of die casting. The design of traditional die casting dies is mainly determined by the experience of engineers. It often requires many times of mold testing and repairing process, which wastes a lot of manpower and financial resources. Improve the efficiency of die casting design and quality of die castings.

The different thickness of the inner gate has an effect on the flow, and further affects the distribution of air pressure, resulting in gas entrainment during the filling process. When 12.0 mid_ and 80% melt filling, air entrainment occurs in the middle of the casting, which makes a small area of air pressure on the left of the casting. When t-1.5 itiiti is filled to 70%, air entrainment occurs on the right side of the casting, and air entrainment occurs on the left side of the casting when it is filled to 80%. In the end, there is a large amount of air entrainment in many parts of the casting. There are many pores in actual production. When t-1.0mFll is filled with 70% ~ 80%, the air entrainment occurs on the right side of the casting. The air pressure distribution of the casting is small, but the inner gate velocity is high, which results in the melt directly eroding the surface of the mold cavity and the surface cracks.
