摘要随着毕业的脚步逐渐地临近，我们迎来了毕业设计这个重要的阶段。这是一次重要的测试与检验，它将统合我们在大学四年里所学的内容，同时也是一次检验我们是否满足社会需求的重要标尺。机械工业素有“工业的心脏”之称，它是其它经济部门的生产手段，也是一切经济部门发展的基础。我有幸学得关于机械的许多知识，我为自己选择机械这一行业而感到自豪。我学习了机械制图、工程力学、机械设计基础、工程材料等诸多学科，对于机械这一行业有了一个相对的了解。在学校课程设计时也能独立运用一些相关知识解决问题，这为我完成毕业设计奠定了基础并建立了自己的信心。但是作为一个初学者，其对于我来说还是有很大难度与挑战的。但老师的指导却如黑夜中的明灯，给我指点了方向。通过老师与相关书籍的指点，我慢慢摸索出了一些方法，同时也了解了模具的各种工艺技术和原理以及之制造技术等等的相关知识。虽说刚开始做毕业设计会很慢，也会有许多错误，但我有自信会很好的完成它。45879

ABSTRACT With graduation footsteps gradually approaching, we ushered in the graduation design of this important stage. This is an important test and inspection, it will integrate the we learned the content we learned in the university four years, and it is also a test whether we meet the demand of social important yardstick. Mechanical industry, known as ”the heart of the industry”, it is the production of other sectors of the economy, also is the foundation of all sectors of the economy development. I had a chance to learn a lot of knowledge about mechanical, I proud of you choose mechanical industry.I'm learning mechanical drawing, engineering mechanics, mechanical design basis, engineering materials, and many other disciplines, for mechanical industry have a relatively understanding. In the school curriculum design also can use some related knowledge to solve problems independently, which laid a solid foundation for me to complete the graduation design and set up their own confidence. But as a beginner, it still has great difficulty and challenge for me. But as the lamp in the dark night, the guidance of the teacher give me advice on the direction. Advice by the teacher and the related books, I slowly grope for out some methods, but also to understand the various technology and principle of the mould and the manufacturing technology of knowledge, and so on. Although just began to do graduation design can be slow, there will be many mistakes, but I have confidence will finish it very well.
