设计简介
摘 要
本设计题目为油箱盖冲压模设计，体现了拉深类零件的设计要求、内容及方向，有一定的设计意义。通过对该零件模具的设计，进一步加强了设计者复合模设计的基础知识，为设计更复杂的复合模具做好了铺垫和吸取了更深刻的经验。
通过分析制件的工艺性可确定制件的成形加工需要一副复合模具完成。复合模是指冲床在一次行程中，完成落料、拉深、冲孔等多个工序的一种模具结构。相对其他冷冲压模具结构而言，它具有以下一些优点：①工件同轴度较好，表面平直，尺寸精度较高； ②生产效率高，受条料外形尺寸的精度限制较小。但需考虑的问题是：模具零部件加工制造比较困难，成本较高，并且凸凹模容易受到最小壁厚的限制

Abstract
The requirement ，content and direction of the design of the deep thin wall plastic parts are embodied on this injection mould design of the plastic parts of long pipe box. The designer’s foundation knowledge of the injection mould design is reinforced and is able to design more complex injection mould through the design.
Through analyzes the workpiece the technology capability to bepossible to determine the workpiece the formed processing needs acompound mold to completeThe compound mold mean the punching machine is in a route of travel, completing to fall to anticipate, a kind of molding tool structure of several work prefaces of etc. of blunt bore.Opposite and other cold hurtle to press the molding tool structure but speeches, it has following some advantageses:The ① work piece is together the stalk degree is better, the surface is straight and even, the size accuracy is higher; The ② produces the efficiency high, be subjected to the anticipates the shape size of accuracy limit smaller.But need the problem of the consideration is:The molding tool zero partses process the manufacturing more difficulty, the cost is higher, and the convex and cave mold is subjected to the thick restrict of minimum wall easily.
