Abstract

An interactive computer program to design a mold cavity with the proper rigging system has been developed. In addition to the pattern and the risers generated as described in Part 1 of this work, the various components of the gating system are generated in complete three-dimensional models by a rational approach. Then they are laid interactively by the user, and united together with the pattern and the risers to result in the three-dimensional model of the mold assembly. Finally, the vents and the mold box are constructed following the user’s interactive specification and then the mold cavity is completed in a three-dimensional geometric model by subtracting the mold assembly and the vents from the mold box. The three-dimensional model of a mold cavity is useful for many related applications such as the solidification simulation for mold evaluation and the NC tool path generation for mold production.
