Combined with the progress in knowledge based engineering(KBE) in design and data diagram of the designing mold base, the basic frame of KBE system of mold base design was presented and its key technologies (knowledge processing, case reasoning and neural network) were researched in detail. According to the resolvability of engineering design process, frame rule method is adopted as knowledge representation and its reasoning method is given in flowchart, and this method that oriented in sub project in engineering improves the knowledge processing ability in KBE system. Integrated with the case reasoning in system, recalling the similar case efficiently improves the mold design ability. Utilizing self learning ability of neural network, the calculation of the set in and mold base dimension are solved using theoretic and experiential equation. According to the practice in factories, this system can enhance the ability of the mold design and analyzing.
