Abstract
The graduation project is the determination of the issues covered car rearview mirror mold design. Haqisuo from Plastic Automotive Trim Co., Ltd.. Internship in the factory process, the understanding of the processing tool, recognizing the importance of mold industry. This paper mainly introduces the car left the rearview mirror is determined to single-cavity injection mold design method and process. The main surface through a single injection, according to the design of product characteristics of convex and concave mold, injection molding machine to choose models to determine the overall structural design, focusing on the design of the oblique derivative of the bending force calculation column to facilitate product release. Assembly through the CAD drawing.This article is divided into three parts, in the first part, introduced the injection mold industry in the modern situation and the purpose and significance of topics. The second part of the show is the root of the characteristics of products, select the type used in injection molding machine, the determination of surface, mold design and structure of the program choice. The third part is the main part of die design, and its specific content, including: forming part of the design calculation, design of gating system, overflow row air-system design, cooling system design, design agencies, as well as Demoulding reset system design, also designed a number of other parts.
Key words: mold; injection mold; casting systems; Demoulding
