Abstract
This thesis explains the model of mechanical drawing teaching product design and injection mold design process. According to the process of teaching mechanical drawing some of the problems exposed, targeted teaching model designed mechanical drawing, mechanical drawing model covers the most important difficulties in teaching the content, and strive to give students the most intuitive visual experience and the most profound understanding. After product design ，design the injection mold die that corresponding to the product and find product improvements at die design process, make it easier to shape, also made it easier for mold manufacturing。
