Algorithm for Die Design of Diecasting

摘要

This paper describes a research work of developing computer-aided die design system for die casting. Approach to the CAD system has been written in circumstance Auto LISP with personal computer. This system has been developed to present algorithms for automation of die design, especially runner-gate system using 3-D geometry. This system quantifies practical knowledge and experiences in die design as formulating procedure. It is possible for engineers to make automatic and efficient design of and it will result in reduction of required expenses and time. It is composed of selection of cast alloy, product design, runner-gate design etc. In addition, specific rules and equations for the system have been presented. An example is applied to cap-shaped cast using the proposed system.
