摘 要
压铸模具是铸造液态模锻的一种方法， 一种在专用的压铸模锻机上完成的工艺。它的基本工艺过程是：金属液先低速或高速铸造充型进模具的型腔内，模具有活动的型腔面，它随着金属液的冷却过程加压锻造，既消除毛坯的缩孔缩松缺陷，也使毛坯的内部组织达到锻态的破碎晶粒。毛坯的综合机械性能得到显著的提高。
本文运用大学所学的知识，了解压铸模具的工作原理，在此基础上，设计一款铝合金箱体压铸模具。通过查找相关资料，了解铝合金箱体压铸模具的内部结构和工作原理，构建了铝合金箱体压铸模具组成结构的总的指导思想，从而得出了该铝合金箱体压铸模具的优点是高效，经济，并且运行效果好，运行平稳的结论。

Abstract
The environment of global economic development, China industries affected by other countries advanced technology at the same time, foreign enterprises and brand spread to more and more Chinese has become an opportunity. Cap pressing machine in industry through a variety of ways have been working with the relevant technology, and constantly improve their own strength and core competitiveness, and narrow the gap with developed countries.
In the new market demand, update the sleeve pressing machine is a pressing matter of the moment. The production of pipe pressing machine equipment manufacturing enterprises to fully tap the potential of the market, vigorously develop the sleeves of large low cost pressing special machinery and equipment, plays a positive role in the evolution of automatic assembly, the assembly of mechanical equipment. There is a large pipe equipment on equipment safety index has strict requirements of production. In the production equipment of enterprises, give full consideration to the possible problems in the operation of the equipment, so as to reduce the noise pollution caused by vibration or improper operation of equipment phenomenon and manufacturing of domestic pipe pressing equipment with global appeal, economic, security and stability of the theme consistent. Increase and production pipe pressing equipment of new energy saving.
Key word: pneumatic manipulator； cylinder； pneumatic loop； Fout degrees of freedom.
