Research on Design Method for the Injection Mold Parting Surface on the Case-based Reasoning(CBR)

On the basis of comprehensive analyses about the automatic design of injection mold parting surfaces, this paper presented a method which introduced case-based reasoning into the computer-aided design of injection mold parting surface, and the general frame of the method was given. The 3D plastic part model was constructed with feature technique. Simultaneity, feature knowledge library which includes the information of parting surface were built with the index of main shape feature. Combined with the similarity solution procedure, the forward-reasoning method was used to realize automatic design of the mould parting surface. The reasoning method and flow of the parting surface position design was given also. As a result, the quality and the efficiency of mold design are improved.
