冷冲压模具毕业设计说明

摘要

模具属于精密机械产品，它主要由机械零件和组成，如成形工作零件、导向零件、支承零件、定位零件及送料、抽芯、推出等。模具与相应的成形设备（如冲床、塑料注射机、压铸机等）配套使用时，可直接改变金属或非金属材料的形状、尺寸、相对位置和性能，使之成形为合格的制件。

模具设计是模具制造的基础，合理正确的设计是正确制造模具的保证；模具制造技术的发展对提高模具质量、精度以及缩短制造模具的周期具有重要的意义；模具的质量、使用寿命、制造精度及合格率在很大程度上取决于制造模具的材料及热处理工艺；模具成本直接关系到制件的成本以及模具生产企业的经济效益；模具工作零件的精度决定制件的精度；模具的寿命又与模具材料及热处理、模具结构以及所加工制作材料等诸多因素有关；模具的安装与使用直接关系到模具的使用性能及安全；而模具的标准化是模具设计与制造的基础，对大规模、专业化生产模具具有极重要的作用，模具标准化程度的高低是模具工业发展水平的标志。

本次设计绘图采用CAD进行，CAD为计算机辅助制图工具，是一款专业机械平面制图软件，具有很强的图象处理功能。

ABSTRACT

The mold belongs to the precision machinery product, it mainly is composed by the machine parts and the organization, like the formed work components, the guidance components, the supporting components, the localization components and the feed mechanism, pull out when the core organization, promotes the organization and so on the mold and the corresponding complete installation (for example punch press, plastic injection machine, compression casting machine and so on) the necessary use, may directly change the metal or the nonmetallic material shape, the size, the relative position and the performance, causes it forming for the qualified work-piece .

mold design is the foundation which the mold makes, the reasonable correct design is correctly makes the mold the guarantee; The mold manufacture technology development to improves the mold quality, the precision as well as reduces makes mold the cycle to have the vital significance; The mold quality, the service life, the manufacture precision and the qualified rate are decided in the very great degree to makes the mold the material and the heat treatment craft; The mold cost directly relates the work-piece the cost as well as the

mold production enterprise's economic efficiency; The mold work components precision decides the work-piece the precision; The mold life with the mold material and the heat treatment, the mold structure as well as processes the manufacture material related and so on many factors; The mold installment and the use directly relates the mold the operational performance and the security; But the mold standardization is the mold design and the manufacture foundation, to large-scale, the specialized production mold has the extremely vital role, the mold standardization degree height is the mold industrial development level symbol This design cartography uses CAD to carry on, CAD is the computer auxiliary charting tool, is section specialty mechanical plane charting software, has the very strong imagery processing function

KEY WORD: The mold design, Row of type，Cold ramming
