6三维塑件
摘要
本次设计的是电器件的注塑模具。所用材料是当前应用较为广泛的材料ABS。在设计中，分析塑件的工艺性。模具结构可采用一模一腔，点浇口进料，注射机采用HTF 80XA型号，并对其相关的数据进行校核,选用FCI型三板模架、滑块抽芯机构。首先根据三维软件设计出分型面，进而设计出型腔、型芯，通过各种手册选择标准模架的绘制，并且进行浇注系统、脱模机构、冷却系统等模具重要结构的设计。最后对设计过程中的相关零部件进行了计算和校核，在无误的基础上进行了模具总装，并利用CAD软件绘制出总装及各主要零件的二维工程图，设计出一套塑料注塑模具
此次设计的过程中查阅了大量的模具设计资料，通过电器件塑料模具的设计与应用，实现了电器件制作工艺上的突破，同原有的设计方法相比，模具的应用不但提高了生产效率而且提升了产品的质量，模具整体设计的思路和要求符合现代设计潮流和未来的发展方向。

Abstract
This design is an injection mould for electrical parts. The material used is ABSwhich iswidely used at present. In the design, the technological properties of plastic parts are analyzed. The mold structure can be used for one mold, one cavity, point gate feed, injection machine adopts HTF 80XA model, and check the relevant data, choose FCI three plate mould frame, slide block core pulling mechanism. Firstly, according to the three-dimensional software, the parting surface is designed, and then the cavity and core are designed. Throughvarious manuals, the drawing of standard die base is selected, and the important structure of the casting system, demoulding mechanism and cooling system are designed. Finally, the relevant parts in the design process are calculated and checked, and the die assembly is carried out on the basis of correctness. The two-dimensional engineering drawings of the assembly and the main parts are drawn by CAD software, and a set of plastic injection mould is designed.
In the process of this design,we consulted a large number of die design data. Through the design and application of plastic dies for electrical devices,we realized a breakthrough in the manufacturing process of electrical devices. Comparedwith the original design method, the application of dies not only improved the production efficiency but also the quality of products. The idea and requirements of the overall design of dies are in linewith the trend of modern design and the future development direction.。
Keywords: electrical appliances; one mold, one cavity; point gate; cooling system; injection mold.
