Knowledge Based Research on Integrated Design Methods of Hot-Runner Technology for Multi-Cavity Injection Molding

The paper analyzed current plastic injection mold hot-runner design, and introduced an approach of conceptual information expressed by knowledge units (KU) and structure units (SU) to establish a knowledge base (KB). Then it designed a multi-cavity mold hot-runner structure based on knowledge driven mechanism, and performed simulation analysis and optimization for the design work. Therefore, based on knowledge transfer, the informational integrated design of the multi-cavity injection mold hot-runner was realized.
