This product is a large aluminum structural die casting mold, mainly used for producing large aluminum alloy structural parts with high strength requirements. The product usually includes large thin-wall areas, multiple reinforcing ribs, complex connection surfaces, mounting holes, and local thick-wall areas, which may cause shrinkage, deformation, cold shuts, and porosity if not controlled properly. Therefore, mold design should focus on optimizing the gating system, cooling system, venting system, overflow structure, and demolding method. This type of mold is suitable for automotive chassis parts, new energy vehicle structural parts, machinery support parts, large housings, and industrial frame components.
