搅拌机料桶注塑模具设计及其动画演示【答辩通过】

摘  要

塑料模具作为塑料工业的基础，随着市场经济的飞速发展受到了极大的挑战。汽车的内饰件、灯具反光镜等塑制品的复杂外形，而钟表、DVD光驱用传动齿轮等塑制件又有很高的精度要求。很短的制模周期、相当的寿命是模具制造的又一重要指标，例如有的只需几十、几百模次（可用简易快速制模法），有的如制瓶用吹塑模却需要上千万模次，制造周期要求越来越短。各种特殊的成型方式的出现等等，都要求塑料模具技术有相应的提高。而计算机技术的飞速发展，适时的给模具技术配上了腾飞的翅膀，彻底改变了手工作坊式的模具设计和制作。在模具设计中广泛的运用CAD（计算机辅助设计），不但抛弃了沿用上百年的图板，而且由于计算机的快速运算和大容量的内存，使得复杂曲面的生成、快速的作图以及丰富制模技术经验的综合、推广成为可能，不少CAD软件已具有某些智能化的功能。例如，有些CAD软件可以运用人机对话的形式，输入塑料制品的某些外形特征（外形主要尺寸、分型面位置、抽心位置、脱模方向等）即可以画出模具总图。

模具技术是一种综合型技术，要求从事模具技术工作者，密切注意和学习相关知识，并运用到实际工作中为模具行业的发展而努力。

ABSTRACT

Plastic mould plastics industry as a base, with the rapid development of the market economy is a great challenge. Cars neishi pieces, plastic products as the reflector lamps and lanterns complex shape, and clocks, DVD player with gear, etc SuZhi pieces and has high accuracy. The molding cycle is short, the life is quite mould manufacturing another important indexes, such as some need dozens, hundreds of mould times (or simple rapid method), some with blow mould as bottle to millions of mould manufacturing cycle times, shorter requirements. Various special molding method of plastic mold, etc., have corresponding technical requirements. And the rapid development of computer technology, timely to mould technology with a pair of wings, thoroughly changed the manual mill of mold design and manufacture. In the mold design of extensive use of computer aided design (CAD), not abandoned used hundreds of years, and because the computer drawing and high-capacity fast operation, the memory of the complex curved surface, fast drawing and rich technical experience of comprehensive, making it possible, many CAD software has some intelligent function. For example, some CAD software can use the man-machine dialogue forms, some of the input plastics contour features (major outline dimensions、parting surface location,、ocation、parting)direction of heart that can draw mould layout.

Mould technology is a comprehensive technical requirements, technical workers engaged in mould, pay close attention to the learning and knowledge, and applied to practical work for mould industry development and efforts.
