第四章，介绍了热流道设计中一个面向装配的三维参数化标准件库的建立方法。
In chapter 4, the method of founding a 3d parametric standard part base for assemble in hot runner design was presented.
因此，在通用CAD平台上进行二次开发建立三维参数化汽车冲模标准件库，将是一条可行之路。
So it is a feasible way to build parameterized standard part library for punching die on the general CAD platform.
设计实践表明该方法不仅设计效率高，而且为三维实体参数化标准件库的设计提供了更有效的途径。
The design practice indicates that this method is not only highly efficient but also provides a more effective approach to 3d standard parts library design.
