手机上盖注塑模具设计

摘要：注塑模具CAD技术是指在注塑模具设计过程中采用CAD系统来辅助设计人员进行模具设计，以便提高模具设计的水平和效率。注塑模具CAD系统是在通用CAD系统的基础上，加载了注塑模具知识和设计经验模块，支持注塑模具设计的基本流程。

随着科学的发展，各种产品的更新换代速度越来越快，而产品的更新是以新产品的造型设计和模具的设计、制造与更新为前提的。模具的设计是模具更新的基础，模具设计工作与产品的更新信息相关。传统的手工设计模式已经不能很好地适应时代的需要，计算机辅助设计与制造已成为许多大型CAD/CAM/CAE软件追求的目标。而在众多辅助设计制造软件中，Unigraphics 软件是当今世界较先进、面向制造业的综合软件。

本设计首先采用UG软件进行注塑件的三维实体造型,针对手机上盖的具体外形尺寸,应用基于特征的实体建模和自由形状建模等知识,使用体素特征、扫描特征、成形特征、特征操作等具体的操作步骤逐步生成手机上盖。其次,利用UG软件中的Mold wizard工具对手机上盖进行拆模，并且对手机上盖模具的模架、定位环、推杆、浇口、合模导向机构、抽芯机构、浇注系统、冷却系统等进行了设计。最后，利用UG软件中的CAM功能对凸模进行仿真加工并生成手机上盖凸模的NC加工程序。

Abstract: CAD technology is the injection mold injection mold design process in the CAD system used to assist designers to mold design, mold design in order to improve the level and efficiency. Injection Mold CAD system is based on the general CAD system, load the injection mold design knowledge and experience in modules support the basic process of injection mold design.

With the development of science, the upgrading of various products faster and faster, while the product update is a new product modeling design and mold design, manufacturing and updated as the prerequisite. Mold mold design is the basis for updating, mold design and product-related updates. The traditional manual design model has not well adapted to the needs of the times, computer-aided design and manufacturing has become many large CAD / CAM / CAE software goal. Assisted in the design and manufacturing of many software, Unigraphics software is the world's more advanced and comprehensive software for the manufacturing industry.

The design of the first injection molded parts using UG software three-dimensional solid modeling,mobile shelters for the specific dimensions,application of feature-based modeling and free modeling the shape of knowledge, use of voxel features, scanning features, shape features, feature operation and other concrete steps to gradually build mobile phone cover. Secondly, the use of UG software Mold wizard tools mobile phone cover for form removal, and mold on the mobile phone cover mold, positioning ring, putter,gate, mold-oriented institutions, core pulling mechanism, gating system, cooling system is designed. Finally, UG CAM software features simulation of the punch process and generate the NC cell phone cover punch processing.
