Scope

Main technical content: 1. This technology forms drainage grooves at the positions corresponding to the rib-forming cavities in the side molds. These drainage grooves are used to increase the size of the flow channels between the rim-forming cavity and the rib-forming cavity. Thus, when the cooling mechanism solidifies the molten aluminum from bottom to top, the drainage grooves can solve the problem of R-angle slag at the junction between the rim-forming cavity and the rib-forming cavity caused by premature cooling, ensuring the mechanical performance quality of the formed hub. 2. During the solidification process, the special design of the drainage grooves at the positions corresponding to the ribs in the side molds avoids the formation of R-angle slag at the heat-bonded areas, ensuring the compactness of the structure, improving the internal quality, and providing greater safety guarantees for the product.
