In the process of Zinc alloy die casting, the filling mode of molten metal is one of the key factors affecting the quality of castings. Many die-casting defects, such as insufficient pouring, cold shuts, pores, and shrinkage, are related to the filling mode. At the same time, the filling mode is also One of the key factors affecting mold life. Therefore, using simulation software to accurately predict the filling process of castings can effectively test the rationality of gating system design and optimize the setting of ingate position, runner size and die-casting process parameters.

The structure of Zinc alloy die casting is characterized by a typical special-shaped structure, with a slightly complicated raised part in the middle and a simple structure on both sides, and there is no obvious plane parting surface. Because the casting is small in size, a mold structure with one mold and two cavities is considered, the left It is designed as casting A, and the right side is designed as casting B, so that a set of parts can be produced at the same time, which is also more advantageous from the perspective of organizing production.
Combined with the structural characteristics of castings, the partition filling method can be used to transport the molten metal to each ingate as uniformly as possible, and ensure that the molten metal entering from the corresponding ingate of each partition is filled in the same direction, synchronously, quickly and smoothly cavity.

The manufacturer tells you to set up an overflow tank in the final filling area to ensure the effectiveness of the exhaust.
