摘  要:随着计算机技术的发展,CAD/CAM技术受到了越来越广泛的关注,成为制造设计领域的核心技术之一。在现代模具设计中,CAD/CAM同样是不可或缺的软件工具。但由于CAD/CAM软件种类多样、模具类型也各不相同,因此无论是在软件选型还是在模具设计过程中都会面临很多问题。基于此,本文首先介绍了CAD/CAM软件在模具设计中的优势,然后介绍了常用的CAD/CAM软件产品,并根据模具设计要求进行了选型分析,最后以底座熔模模具的设计为例,探讨了基于Pro/E的底座熔模模具设计思路和要点。希望本文的研究可以为相关领域提供借鉴。

Abstract: With the development of computer technology, CAD/CAM technology has attracted more and more attention and become one of the core technologies in the field of manufacturing design. In modern mold design, CAD/CAM is also an indispensable software tool. However, due to the variety of CAD/CAM software and different mold types, there are many problems in the process of software selection and mold design. Based on this, this paper first introduces the advantages of CAD/CAM software in mold design, then introduces the commonly used CAD/CAM software products, and analyzes the type selection according to the mold design requirements. Finally, taking the design of base investment mold as an example, the design ideas and key points of base investment mold based on Pro / E are discussed. I hope this study can provide reference for related fields.

近年來,在现代计算机技术的推动下,计算机辅助设计及制造(Computer Aided Design and Computer Aided Manufacturing,CAD/CAM)技术受到了越来越广泛的关注,并且逐渐成为制造设计领域的核心技术之一[1-2]。模具设计作为制造领域的重要组成部分,采用CAD/CAM技术不仅可以实现三维绘图、图形编辑、曲面加工、仿真模拟、动态显示等一系列基本的设计功能,而且为设计过程中的数据管理、数据共享、资源调度提供了重要的技术支撑。

1  CAD/CAM在模具设计中的优势

CAD/CAM是机械设计技术和机械制造技术的复合体,通过CAD技术可以很容易设计出满足设计使用需求的产品原型,而采用CAM技术则可以高效、精确地将设计模型制造生产出来[3-4]。CAM与CAD在功能上紧密衔接,通过CAD设计出来的模型可以由CAM软件进行交互式编程,形成加工轨迹参数,可以很好地满足复杂结构的高效加工,进一步压缩制造的周期,提高了制造效率和质量。……
