摘要 随着模具工业的迅猛的发展，模具设计与制造以成为一个行业，工业生产中普遍采用模具成型工艺方法，有效地保证了产品的生产率和质量，使操作技术简化，还能省料、节能，获得显著的经济效益。 由于产品的材料和工艺特性不同，生产用的设备也各异，模具种类繁多，但用的最为广泛的大约有以下几种：冷冲压模、塑料成型模、锻造模、精密铸造模、粉末冶金模、橡胶成型模、玻璃成型模、窑业制品模、食品糖果模、建材用模等。其中以冷冲压模、塑料模的技术要求和复杂程度较高。 全套图纸，加 Abstract With the rapid development of industrial molds, mold design and manufacturing to become a trade, industrial production methods commonly used by die molding process, effectively ensure the productivity and quality of products, so that technology simplifies operations, but also material saving, energy saving, achieve significant economic benefits.  Due to the characteristics of different materials and processes, production equipment is different, mold a large variety of the most widely used around the following: cold punching mold, plastic molding, forging mold, die casting, powder metallurgy mold, rubber molding, glass molding, ceramic products, mold, food and candy mold, mold and other building materials used. Among them, cold stamping dies, plastic and complexity of the technical requirements of the higher. My graduation project is the progressive die, stamping die mainly to isolated or forming the sheet metal processing methods are workpiece. Because molds are mainly high volume production, and stamping die products can ensure the dimensional accuracy and quality, mold design and manufacture of primary consideration to the mold design can meet the design process the workpiece, can process a qualified parts, and, later, maintenance and storage is reasonable. In this design, not only to consider making the parts to make to meet the job requirements, but also to ensure its service life.
