Abstract
Descriptive geometry of the problem is to study geometry of space and graphic icon of the law school he was an engineering drawing of the theoretical basis. Descriptive geometry familiar with the basic theory and mastery of descriptive geometry to solve the problem of methods and techniques, which will enrich the space engineering and technical personnel imaginative, and engaged in productive work and provide a powerful technology tools and instruments. In order to better learn the descriptive geometry and engineering drawing, design a teaching Die Yi, will give us an intuitive understanding of three-dimensional model of the project is to map said. And designed a process to injection mold products. UG NX 5 of the MOLDWIZARD module features of the product characteristics die structure design. Determine the type face, pouring system, introduced institutions, cooling system, the choice of injection machine,calculating the size of the molding components. According to Detroit and parts injection mold injection machine at the request of the various parameters of the check. Finally, a set of AutoCAD software rendering mold assembly and parts plans.
