This paper briefly outlines the purpose, significance, stamping mold market situation and development trend of domestic and international topics. The product was analyzed to determine the detailed processes and process solutions. Following the general procedure of stamping die design, calculation and design of the main components of these two sets of mold. Blanking - Punching Compound Die four-pillar standard mold, bending mold using the middle pillar round standard mold and selected the appropriate stamping equipment. In addition, the final design of the mold stamping process to reach reasonable solutions, mold structure type is correct. Ensuring the accuracy of the relative position of the holes and the shape of the workpiece, to improve the machining accuracy. Such a structure designed to ensure reliable operation and stamping mold work product requirements of mass production. And the analysis of existing knowledge representation and its problems, as well as intelligent stamping die design features, the proposed method is based on knowledge representation and application of XML (eXtensible Markup Language) language. Knowledge reuse in design theory and conceptual model, based on research and analysis of the various stages of stamping die design knowledge reuse method to establish the level of design knowledge reuse and model, and analyzes presented in CAD, KM and CBR technology, based on how the way to achieve knowledge reuse throughout the design process Key words: Blanking-punching compound die；Single-slot module processes；Stamping separated spaces；XML
