Abstract: Design of gating system of a die-casting die is a non-trivial task, which depends on a number of parameters influenced by part design and die-casting alloy. Today, a lot of CAD/CAM tools are used for design, development and manufacturing of die-casting dies. However, design of a die-casting die and its gating system, still depend on a die-casting expert and require lot of time. Present work is about computer-aided design of gating system for die-casting die. System proposed in this paper takes CAD file of the die-casting part as input and uses process knowledge to determine different parameters of the gating system. Design of various components of the gating system, namely runner, gate and overflow is attempted. A feature library is proposed, which together with parametric design, generates CAD model of the components of the gating system. The system would be useful to bridge the gap between design-manufacturing integration for die-casting.

Keywords: die casting dies; die design; CAD; feature-based design; gating systems; computer aided design; parametric design.
