摘要
在现代工业中，模具工业已经成为制造业的基础，这一观点随着全球制造业向我国转移的过程中被越来越多的有识之士所意识到。而在模具行业中塑料模又是其重中之重，此种模具占模具行业值的50%以上，我国的塑料成型模具设计，制作技术比较晚，整体水平还比较低。目前单型腔、简单型腔的模具达70%以上，占主导地位。
本论文介绍了吸尘器万向轮注射模具的设计过程。从万向轮的测绘，PRO/E的三维建模，分型面的确定，型腔数目和布局的确定，注射机选择，浇注系统设计，冷却系统设计，模板及其标准件的选用，脱模机构的设计，成型部件的设计等一一进行了详细的介绍。 塑件的中心圆柱内有四个小的加强筋，难加工，是本设计的难点，需要用到型芯镶件。
通过本设计，可以对注射模具有一个初步的认识，模架的结构及其动作原理都有了一定的了解。注射模是安装在注射机上的，因此在设计注射模时应该对注射机的有关技术规范进行必要的了解，以便设计出符合要求的模具，同时选定合适的注射机型号。

 Abstract
In modern industry, die industry has become the basis of manufacturing,this view as the process of the global manufacturing transfer to China being awared by more and more insightful people. The plastic mould is top priority in the die industry, such mould of the die industry production value over 50 percent. China's plastic mold design, production technology relatively late, the overall level is still relatively low.At present, single-cavity and simple cavity of the mold more than 70 percent, it’s dominated.
This paper introduced the design process of carden-whell of dust collector. Introduction from the carden-whell’s modeling, determined of parting face, determined of the cavity’s number and layout,choiced of injection,designed of pouring system,designed of cooling system,choiced of follow board and standard unit,designed of mould emptier,designed of forming part and so on. Plastic’s center has four litter dabber, difficult processing,design become difficulty, need using core inserts.
Through this design,I can have a preliminary understanding of the injection mold ,the die carrier’s frame and action principle.Understanding the selected of die carrier and  injection machine need through to calculation the various  size and check the Strength.
