模具是工业产品生产用的重要工艺设备，模具工业已是工业发展的基础，许多新产品的开发和研制在很大程度上都依赖与模具的生产。可以预言，随着工业生产的不断发展，模具工业在国民经济中的地位将日益提高，并在国民经济发展过程中发挥越来越重要的作用。在冲压零件的生产中，合理的冲压成形工艺、先进的模具、高效的冲压设备是必不可少的三要素 。 本文介绍了止动件冲压模具的设计，先介绍了对工件进行工艺分析和模具设计的要点，然后介绍了模具设计的思路，模具的主要结构和主要零件的设计。最后确定了选用冲孔落料复合模。
本次设计绘图采用AotuCAD，以AotuCAD为计算机辅助制图工具，使用简单，方便快捷，而且有极强的图形处理功能，可以大大缩短绘图的周期，在国内使用的较广泛。 电子签章技术tz15关键词: 模具,落料,冲孔。
ABSTRACT
The mold was the important process unit which the manufactured products production used, the mold industry already is the industrial development foundation, many new product's developments and the development relied on to a great extent with mold's production. May predict that along with industrial production's unceasing development, the mold industry will enhance day by day in national economy's status, and plays more and more vital role in the national economy developing process. In the ramming components' production, the reasonable ramming forming craft, the advanced mold, the highly effective ramming equipment are the essential three essential factors. Ramming processing characteristic: Because the cold stamping processing has the above prominent merit, therefore obtained the widespread application in the volume production, holds the very important status in the modern industry production, is the defense industry and in the consumer industry production the essential processing method. this article introduced the lock ramming mold's design, introduced first carries on the process study and the mold design main point to the work piece, then introduced the mold design mentality, mold's primary structure and the major parts design. Finally had determined sel
ects the punch holes to fall the material superposable die. the this design cartography uses AotuCAD, take AotuCAD as the computer auxiliary charting tool, the use is simple, facilitates quickly, and has the greatly strengthened graphic processing function, may reduce cartography greatly the cycle, in domestic use widespread.
key word: The mold, falls the material, the punch holes.

前 言
一、概述
所谓模具，就是在工业生产中，用各种压力机和装在压力机上的专用工具，通过压力把金属或非金属材料制出所需形状的零件或制品的专用工具的统称。
近年来，国内已较广泛地采用一些新的塑料模具钢，如：P20、3Cr2Mo、PMS、SMⅠ、SMⅡ等，对模具的质量和使用寿命有着直接的重大的影响，但总体使用量仍较少。塑料模标准模架、标准推杆和弹簧等越来越广泛地得到应用，并且出现了一些国产的商品化的热流道系统元件。但目前我国模具标准化程度和商品化程度一般在30%以下，和国外先进工业国家已达到70%-80%相比，仍有很大差距。
