Based on the method of design for assembly (DFA), the expression and processing techniques of multi-knowledge for injection molds have been reseached. The assembly and evaluation models of injection molds have been established and the assembly connections and association of the structural dimensions are achieved. A knowledge-based and DFA integrated system for injection molds has been developed. A three-dimensional realistic filling and post-filling simulation has also been accomplished. This simulation based on solid/surface models breaks the bottleneck which restricts the development and applications of injection molding simulation systems, and makes the large-scale application of the simulation possible. Three PhD theses, one monograph and eight pieces of papers in foreign periodicals have been completed. First-class Chinese Colleges Award of Science and Technolgy and Second-class National Award of Science and Technolgy Development have been granted.
