摘 要 模具工业是制造业中的一项基础产业，我国国民经济的高速发展对模具工业提出了越来越高的要求。其中塑料模具因为塑料工业的快速增长也备受关注，在近年来取得了很大的发展。冲压模具是冲压生产必不可少的工艺装备，是技术密集型产品。冲压件的质量、生产效率以及生产成本等，与模具设计和制造有直接关系。 关键词：冲压模具 级进模 垫圈 Abstract Mould manufacturing industry is one of the fundamental industry, the rapid development of Chinas national economy of die and mould industry is increasingly high requirements. Including plastic mould plastics industry because of the rapid growth of attention, also in recent years has achieved great development. Stamping mould pressing craft is essential to production equipment, is skill-intensive goods. The stamping production efficiency and the quality and cost of production, and die design and manufacture. Therefore, we are simply here in the mould design, mold design and research to understand the method This design has a set of punching die, dropping material. After data access, first to spare parts, the process analysis process analysis and comparison, punch blanking process, by cutting force, the top pieces, unloading etc, press computation model. To analysis the process for stamping mould design for the selection of the mould. The design that will die after each type of work will die parts design process. In the first part of the document, mainly describes the development of stamping mould, illustrates the importance of stamping mould design and the significance of the stamping, then to process analysis, completed the process. The second part of the design layout diagram parts, material utilization. Then punching process of calculation and punch die working parts of the design and calculation, stamping equipment selection. Finally the design of main components and parts for the selection of the design, mold and die forming, and provide basis for various sizes of assembly drawings. Through the front design draw all parts and mold assembly. Through the design of a complete set of gasket parts design, including the calculation to draw from drawing. And expounds stamping progressive die structur
