摘要：模具制造是现代工业中非常重要的环节，可以说是机械制造过程当中的核心，各种零件从设计到成形产品，模具在其中发挥了巨大的作用，随着模具技术的不断成熟和完善，再加上工业领域对产品的要求越来越高，模具也朝着更加精密的方向发展。而多工位级进模由于高效和便捷，有着其他模具难以比拟的优势。

本论文主要介绍了电脑光驱上盖钣金件的级进模设计，在设计模具之前，首先对该钣金件的结构进行了详细的分析，其次通过UG进行光驱上盖的三维建模，利用三维模型得到设计所需要的参数信息，然后根据这些信息画出模具的设计草图，分析出模具应用中可能存在的一些问题，根据这些问题进行模具的优化，最终设计出想要的模具，这就是本次模具设计中的一般过程。钣金件的模具结构设计是否合理关系到零件的质量和企业生产是否高效，为了使本文设计的模具满足零件生产的要求，在设计中使用了CAD和UG画图软件进行模拟分析，利用计算机的三维建模更加直观地分析和了解加工零件的外形尺寸和结构特点，优化了设计方案，最终完成了该钣金件的模具设计。

Abstract：Mold manufacturing is a very important part of modern industry, it can be said that the core of the machinery manufacturing process, a variety of parts from design to forming products, mold in which played a huge role, with the mold technology continues to mature and perfect, and then Coupled with the industrial areas of the product requirements are getting higher and higher, the mold is also moving in a more precise direction. And multi-station progressive die due to efficient and convenient, with other molds difficult to compare the advantages.

This paper mainly introduces the design of progressive die for sheet metal parts of computerized optical drive. Before designing the mold, the structure of the sheet metal is analyzed in detail. Secondly, the three-dimensional modeling of the optical drive cover is carried out by UG. Dimensional model to get the design of the required parameters of information, and then based on the information to draw the mold design sketch, analysis of the mold application may be some of the problems, according to these problems to optimize the mold, the final design of the mold, This mold design in the general process. Whether the mold structure design of sheet metal parts is reasonable depends on the quality of the parts and the production efficiency of the enterprise. In order to make the mold designed in this paper meet the requirements of the parts production, CAD and  UG drawing software are used in the design to simulate and use the three- Modeling more intuitive to analyze and understand the machined parts of the external dimensions and structural characteristics, optimize the design, and ultimately completed the sheet metal mold design.
