Abstract: | On the basis of the comprehensive analysis about the automatic generation of the injection mold parting surface,the parting surface design method which introduces knowledge and case-based reasoning (CBR) into the computer-aided design is described by combining with the actual characteristic in injection mold design,and the design process of case-based reasoning method is also given.A case library including the information of parting surface is built with the index of main shape features.The automatic design of the mold parting surface is realized combined with the forward-reasoning method and the similarity solution procedure.The rule knowledge library is also founded including the knowledge,principles and experiences for parting surface design.An example is used to show the validity of the method,and the quality and the efficiency of the mold design are improved. |
