文档介绍：摘要
《圆珠笔顶杆注射模设计》是编写者两个月以来所编写的毕业设计说明书。主要介绍:注射模的整个过程,包括成型零部件、推出机构、流道等一些设计。在论文书写过程中,通过一个月的时间对原始资料进行搜集,充分考虑模具的各种结构并和指导老师及同学之间进行讨论,最终选择了论文所写的模具结构。
本论文的资料大多是编写者结合三年所学的各方面的理论知识完成的,包括机械制图、公差与配合、工程力学、机械设计、注射模具成型、工程材料等;一部分是通过查手册所得;还有少部分是同学之间的交流和自己三年的实习总结。
关键词:三板式、点浇口、侧抽芯
Abstract
"Pen mandrel design of injection mold" is author of two months since graduation written instructions. Focuses on: the whole process of injection mold, molding parts, including the introduction of institutions, such as some of the design flow. In the paper writing process, through the month of the original data collection, take full account of the various structures and mold and guide discussions between teachers and students, the final choice of papers written by the mold structure.
Most of the information in this paper is bination of three writers have learned plete all aspects of the theory of knowledge, including mechanical drawing, tolerance and cooperation, engineering mechanics, mechanical design, injection molding, engineering, materials, etc.; part of the proceeds by check the manual ; there are a small part of the exchange between the students and their three-year internship summary.
Keywords: three plate, point gate, side core pulling
