Abstract: Injection moulds play an important role in the industry. The high demand for automated design and short lead time has remained as the bottlenecks in the mould industry. The current parting systems cannot fully satisfy the parting requirements in terms of speed, quality and functionality for complex moulded products.This research presented a robust parting system, which provides powerful and compatible parting methodologies for moulded products. An automated parting approach was developed to automatically identify cavity/core faces, parting lines, and undercut features. An error correction and feedback system was developed to visibly locate and correct possible errors during the parting process. Automated and novel approaches were developed for creating the parting and shut-off surfaces based on geometry requirements and mouldability criteria. An automated parting approach for multi-injection moulds was presented to generate the sets of cavity/core inserts and their local tools corresponding to each moulding injection stage.
