电话机外壳塑料注射模具设计(CAD、3D)

电话机外壳塑料注射模具设计
摘要
随着近代工业的发展，塑料的应用日趋广泛，从而使之相适应的塑料制造业蓬勃兴起。模具已是工业生产的主要工艺装备，模具工业已逐渐成为国民经济的基础工业。根据日常生活的需要，本次设计的课题是电话机外壳注塑模设计。
首先介绍了我国塑料模具的现状、发展趋势及我国塑料模具发展的新技术，其次围绕电话机机座下壳模具进行了设计，其主要内容包括 ：针对制品的结构特点，确定模具的型腔数目、分型面以及脱模机构。选择合理的浇注系统和冷却系统。分析并设计注塑工艺，制定合理的注塑工艺流程，正确选用注塑设备。然后查阅模具设计手册，选择模架，确定模架的结构尺寸，完成模具的总体设计。同时充分利用计算机绘图软件对零件进行设计, 形成了整套注塑模具CAD图。利用Pro/E对零件进行三维造型, 并实现零件的三维装配。最后讲述了塑料模具的制造:模具的生产过程、模具的主要加工方法及模具的机械加工，并且对典型零件加工工艺进行了分析并制作了注射成型工艺。通过本次设计，对模具整个设计过程有了较好的了解。

Telephone shell injection molding design
Abstract
With the development of modern industry , the application of plastic is widespread day by day . which causes the plastic manufacturing industry adapts to emerged vigorously accordingly. Mold has been a kind of main technological equipments. Die industry has become foundation industry of national economy.Based on the requirements of daily life,the topic of this design is Telephone shell injection molding design
   First ,the article introduced the present situation of plastic mold ,the trend and new technology of the development in our country .Second, it carry on the design Telephone under the seat shell mold.Its primary coverage includes: According to the construct features of the product, numbers of mold cavities and the parting surface and the demoulding machine are determined. Reasonable pouring channel and cooling systems are selected. And then injection technology is analyzed and technology process is made reasonably and the injection equipment is selected correctly. A mold carrier is selected by looking up mold handbook and the die carrier construct size is determined. At last, the global design of the mold. And drawing software is used to design parts, and a series of CAD drawings are completed. Then 3D drawing of parts are designed by Pro/E and 3D assembly of parts are carried out.Finally the article narrated the manufacture of plastic mold:the production process,the main processing method and has carried on the analysis to the typical components processing craft and the mold Machining and the production of injection molding process . Through the project of the mold, the overall process of the design has been clearly and directly known.

Keywords　plastic mold ;design of compression mold ;mold manufacting;    process.
