模具专业的吧？我也是模具应届毕业生哦。多翻翻书吧，多逛图书馆。模具的意义呢？差不多每本模具书上的绪论都会讲到，你自己看一下。我给你一小段看一下：
模具是工业产品生产用的重要工艺装备，在现代工业生产中，60%-90%的工业产品需要使用模具，模具工业已经成为工业发展的基础，许多新产品的开发和研制在很大程度上都依赖于模具生产，特别是汽车、摩托车、轻工、电子、航空等行业尤为突出。而作为制造业基础的机械行业，根据国际生产技术协会的预测，21世纪机械；制造工业的零件，其粗加工的75%和精加工的50%都将依靠模具完成，因此，模具工业已经成为国民经济的重要基础工业。模具工业发展的关键是模具技术的进步。
好了，手酸了，你自己去找吧
十万火急，关于模具论文摘要翻译，小弟感激不尽~~~
The design of the parts for silencers liner. Muffler liner thickness of 0.8mm using SALD-80 aluminum plate to ensure sufficient strength and rigidity at the same time guarantee a certain degree of high temperature and corrosion resistance. Simple symmetrical shape of the parts, in favor of drawing, cutting-edge blanking. Materials with high plasticity, ductility of the plate gap.
To be in the mold design to conduct a comprehensive analysis of the workpiece, and then to determine a reasonable job of stamping technology to commit crimes in order to obtain high precision and high efficiency, long life of the mold and the best cost-effectiveness of technology.
First of all parts for process analysis, there is deep drawing, punching, cutting-edge processes. Less as a result of processes to consider mold manufacturing costs, the ordinary single-mode processes can meet the requirement, the process menu and drawing die punching die trimming program production process can reduce production costs. After completion of the calculation and analysis of the main design tool, the punch, die part of the design work, the main components of the structural design, choose a suitable mold material.
Keywords: stamping die, deep drawing, punching, trimming, muffler liner
