This product is a large frame structural die casting mold, mainly used to produce large aluminum frame parts, support bases, automotive structural parts, and industrial equipment structures with high load-bearing requirements. The product uses a multi-cavity lattice rib structure, offering light weight, high strength, and good rigidity, but it requires excellent filling, venting, cooling, and demolding performance. Mold design should properly arrange gating systems, overflow grooves, venting channels, slider core-pulling, and cooling channels to reduce cold shuts, porosity, shrinkage, and warpage. This mold type is suitable for lightweight automotive structures, equipment brackets, engineering machinery, and large aluminum load-bearing parts.
