电风扇塑料叶片模具设计
摘要
本次设计的题目是基于UG电风扇塑料叶片模具设计,结合自己所学的知识,通过对UG环境的认识,然后对塑件成型工艺的详细分析,深度剖析电风扇塑料叶片的结构形式、在使用中的性能,甚至包括电风扇模具设计时精度的高低程度。在本设计中,通过对成型零部件,浇注系统和分型面的全面的设计,并且通过计算,确定了对电风扇塑料叶片的温度控制系统的设计,通过分析,然后根据自己所学的知识进行计算,最后确定塑料成型模具材料的选择,同时,也确定对注射机型号的选择。最后本设计用UG8.0创造具有三维实体的模型,并且用UG绘图版本测绘出电风扇叶片的二维工程图,通过这样一系列的分析计算,最后设计出电风扇塑料叶片的模具。并且生成工程图。通过这次设计,让我对模具有了更深层次的理解,并且更加坚信模具美好的未来。随着科学技术的发展,模具必将迎来更加广阔的天空。

ABSTRACT
The topic of this design is based on UG fan blade mould design, combinedwith their learned knowledge, through the understanding of the UG environment, and then detailed analysis of the plastic molding process, depth analysis of the structure of electric fan plastic blade, in the use of performance, including electric fan mould design of high and low degree of precision. In this design, through to the molding parts, gating system and overall design of the parting surface, and through calculation, determine the temperature control system for electric fan plastic blade design, through the analysis, and then calculated according to their own knowledge, and finally determine the plastic molding mold material selection, at the same time, also determine the choice of injection machine number. Finally this designwith UG8.0 create three-dimensional entity model, and use UG graphicsversion 2 d engineering drawing of surveying and mapping out the electric fan blades, through this a series of analysis and calculation, and finally designed electric fan plastic mold of the blade. And generate the engineering drawing. Through this design, let I to the mold have a deeper understanding, I believe even more strongly and mold the beautiful future. With the development of science and technology, mouldwill have a more broad sky.
