基于PROE塑料小铲子注射模设计 摘要 针对塑料小铲子的构造还有有关的数据进行分析，将加工这个塑料产品的模具生产出来。在设计这个模具的过程里面，包括了对塑料加工产品构造的设计，对塑料加工产品模具里面流量的分析，还确定了使用哪一种注塑机，使用哪一种模架，对注塑机的有关数据进行了校核，之后阐述了这个模具里面怎么去设计分型面，怎么去设计浇注系统，怎么去设计成型的零部件，怎么去设计滑块部分，怎么设计冷却系统，最后还将加工成型零部件的工艺过程确定下来了。 设计模具的时候，使用的很多有名的设计分析软件，通过软件对模具的相关数据进行分析和设计，这样一来，设计的效率就大大的提高了。 设计好全部的模具之后，我已经可以利用软件对它进行相关的分析，会通过计算的方式确定参数，根据有关经验将参数确定下来，这样一来对精密的注射模具就非常了解。 关键词：塑料小铲子；注射模具；注塑机；浇注系统，冷却系统 Abstract Accordi
