球形端盖造型与模具设计
摘要
我所学习的专业是模具设计与制造专业，这次的设计是球形端盖造型与塑料模具设计。该设计结合大学三年来所学习的专业知识和CAD软件所设计出的一套塑料模。
本文首先简要的概述了塑料模在社会领域中的作用及其以后的发展方向，点明模具设计的重要意义。然后依据工件图进行工艺性分析，进而确定了设计方案，计算出模具工作部分的尺寸，设计出工作零部件；然后依据设计要求选择出各个标准零部件，然后设计出模具的总装配图。在设计中，最重要的就是设计方案的确定、坯料的计算和选取以及工作零部件的设计，这是设计的关键，这些设计的正确与否直接关系到成本的高低和设计模具能否正常工作；在设计的最后，总结了自己的心得和体会，并对我的指导老师表示感谢。
为了我的设计更加简明易懂，在设计中，我用了十几张零件图来说明我的设计意图，安插在设计任务书中。最后画出一幅球形端盖塑料模装配图和主要工作零部件零件图若干张。
通过本次设计使我不仅掌握了塑料模具设计的一般流程，更学习到了好多课本上没有学习到的知识，使我受益匪浅。
关键词：模具设计与制造、CAD软件、工艺性分析。
Head modelling and mold design of drain pipe
Summary
The speciality of study of our institute is the mold design and speciality of making, the graduation project this time is head modelling of the drain pipe and plastic mold design. It's time to design and combine the professional knowledge of study and a set of plastic moulds that CAD software designed over the past three years of university.
This text the brief plastic role in social field of mould of summary and developing direction afterwards at first, point out in the important meaning of mold design. Then carry on the craft to analyse according to the work piece picture , and then has confirmed the design plan , calculate out mould work some size , design the job spare part; Then choose each standard spare part according to the designing requirement , then design the total installation diagram of the mould . In the design, the important one is sureness of the design plan , calculation and choosing and working the design of the spare part of the blank the most, this is the key to designing, whether these ones that are designed involve directly or not correctly whether the level of the cost and design mould could work normally; At the end that is designed , have summarized one's own gains and experience , and express thanks for my counselor.
More concisly and easy for my design understands , in the design, I state my design intention with a dozen parts picture, assign into design specifications . Draw a drain pipe and several plastic mould installation diagrams of very beginning and spare part pictures of the groundwork finally.
Make me not merely grasp the general procedure of plastic mold design through graduation project once, study to the knowledge not learning to get on many textbooks even more, benefit me a great deal.
