摘 要
关于模具发展趋势,我认为这主要取决于两个方面,即一方面是模具为之服务的各行各业的发展趋势,另一方面是整个社会和世界科学技术的发展趋势,这实际上就是需要和可能。模具是为制件,也就是成形产品服务的,因此模具必然要以制件(成形产品) 的发展趋势为自己的发展趋势,模具必须满足他们的要求。制件发展趋势主要是轻巧、精美、快速高效生产、低成本与高质量,每一项都预示了模具发展趋势。
本文为旅行箱拖手塑料套的产品设计到整个注塑模的设计过程,即对长140mm、宽30mm、高20mm拖手塑料套的注塑模具设计。塑料套的外形设计有防滑纹理,在侧边设有固定的螺丝孔以便固定在伸缩支架上。其螺钉孔根据设计要求采用侧向抽芯机构进行抽芯,然后通过顶杆将制件顶出。稳重介绍了拖手塑料套的外形、结构等设计要求,制件的结构分析,制件的工艺性分析,制件质量、体积计算,材料、生产批量的确定,成型方法的选取及成型设备的选择,注塑模的结构设计,在设计模具时的相关计算,模具机构设计,注射机的选择及其校核,成型零件的相关计算及其校核。在设计中进行大量的计算,如成型零件工作尺寸的计算,型芯、型腔径向和高度计算,推杆直径及其数目的计算等。由此在整个设计计算的过程中,确定了模具的结构及相关的零部件。在整个模具的设计过程中采用CAD/CAM设计系统进行一体化设计,用PROE软件进行塑件的三维造型及其分析,用AUTOCAD进行二维的工程图二维设计。

Abstract
About mold development trend, I think it depends mainly on two aspects, that is, on the one hand is development trend of the mold service for all walks of life, on the other hand, the whole society and the world trend of the development of science and technology, it is actually need and possible. Molds for the parts, that is, forming products and services, so the mold must to stamping forming products () for their own development trend, the development trend of die must meet their requirements. Development trend of the main parts is light and elegant, fast and efficient production, low cost and high quality, each announced a mold development trend.
The thesis gives a detailed introduction the process of an injection mold’s design, which is from product design to the whole plastic injection mold. This is a design for a plastic injection mold whose length is 140mm, 20mm in width, 20mm in height. The form design for a plastic sleeve has skidproof textures. Its broadside has screw eyes . The function of the hole is used to fix plastic sleeve on the telescoping shoring column. According to the design, its screw eyes are required to use a side core-pulling mechanism to do side core-pulling. After that, the knockout pin pushes out a fabricated part. This paper introduces the design standards of a drag hand plastic’s form, structure, etc, the process analysis of a fabricated part’s quality, volume calculation,materials, the confirm of production lot, the choice of molding methods and the choice of mold equipment, the injection’s structural design, the relative calculation in designing a mold, a mold’s mechanism design, the choice and check of an injection machine, relative calculation and check about molded parts. Meanwhile, it explains the working processes. Plenty of calculations during the design are the calculation of working dimensions for molded parts, the calculations of core, cavity diameter and the mold’s height, the calculation of a push rod’s diameter and the number of push rods, etc. So, the mold’s structure and some relative components are confirmed during the process of the calculation in the whole design. CAD/CAM design system is applied to in the design process of the whole mold. At the same time, PROE software is used to form 3D mold and its analysis, AUTOCAD is used to export 2Dengineering drawing.
