A SYSTEMATIC APPROACH FOR COMPUTER-AIDED GATING-SYSTEM DESIGN FOR DIE CASTING DIES

Multi-gates are often used in the die-casting die design to provide proper feed of the molten metal to the cavity for obtaining a sound casting. Although a number of systems for design of gating-systems are available they do not help much to design multi-gates. A computer aided system for gating-system for die-casting die-design with multi-gates is proposed in this paper. The proposed system helps to generate parameters of the multi-cavity die taking into account a multitude of factors, such as part design, material properties, process data and die-casting machine information. The parameters so generated are applied on selected gating-system feature existing in the library to complete the design of gating-system. The system generated results for industrial case-study parts are in tandem with the industry practices. The proposed system would greatly help bridge the existing gaps between design and manufacturing for die-casting die-design.
