文档介绍：摘要
模具是利用其特定形状去成型具有一定形状和尺寸的制品的工具,按制品所采用的原料不同,成型方法不同,一般将模具分为塑料模具,金属冲压模具,金属压铸模具,橡胶模具,玻璃模具等。因人们日常生活所用的制品和各种机械零件,在成型中多数是通过模具来制成品,所以模具制造业已成为一个大行业。在高分子材料加工领域中,用于塑料制品成形的模具,称为塑料成形模具,,是当代高分子材料加工领域中的重大课题。
本次毕业设计是电风扇旋扭,它所要达到的要求:要能耐高温,绝缘性要好,耐气候性强,刚性,韧性佳,通过对产品的各种性能分析,选用材料为ABS,该塑件的厚度为1mm,公差等级为IT5级。它是用来调节风速和定时的,能够满足人们的热天对风力和吹风长短要求,同时也起到美观的作用。

ABSTRACT
Mold is used to shape the specific shape of a certain shape and size of products tools used by the products of different raw materials, different methods shaped general layout will be divided into plastic molds, metal stamping dies, metal die-casting molds, rubber molds, glass molds. It is used in the daily life of products and various mechanical parts, mostly in the shape of heads through to finishe products, it has e a major instrument manufacturing industry. In the field of macromolecular materials for plastic products shape the instrument, known as plastic molding shape. Plastic molds optimized design is contemporary in the field of macromolecular materials processing major issue.
The graduation design is fanner knob and, it will reach request: to high temperature, insulation can strong sex is better, resistance to climate, rigid, toughness good, through various performance analysis of products, choose materials for ABS, the thickness of plastic parts for 1mm, tolerance grade IT5 level for. It is used to regulate the speed and timing, can satisfy people's hot weather blowback for wind and length of requirements, while also play beautiful role.
Key words :Plastic mould; materials; Fanner knob
