Mold tool configuration to minimize undercuts

Abstract

A methodology is presented for obtaining mold configurations with a minimum number of undercuts. It identifies optimal draw directions and associated parting line locations that minimize the number of undercuts, thereby obtaining a good mold configuration. The interaction of the allowable draw ranges of the concave regions of the part determines the allowable draw direction range. The allowable draw direction range for the part and its interaction with surfaces within the convex region define its parting line location. Once the draw ranges and parting line locations are identified, an algorithm selects the optimum draw direction and parting line location that minimizes the number of undercuts and results in an easy-to-make mold.
