摘要：

The application of a sweep operation to a solid (a solid sweep) results in a complex solid that can be used for obtaining the core and cavity of injection-moulded or die-cast components. The paper describes a method that is based on solid-sweep operations for modelling mould geometry without the creation of undercut or detached objects. In particular, algorithms based on heuristic search techniques for selecting the parting direction are presented. These algorithms can be used for the selection of the parting direction of a simple 2-piece mould or a mould with external side cores. With the proposed solid-sweep operation, they form a basis for automation of the mould design process.
