摘要
注射模具是模具工业的重要发展方向，也是衡量一个国家产品制造水平高低的重要标志。模具 CAD/CAE/CAM 技术的应用从根本上改变了传统的产品开发和模具生产方式，大大提高了生产效率、产品品质以及企业自身的竞争力。

Abstract
Injection molding is an important direction of development of mold industries, it also is an important indicator of the level of one country’s industry. The application of molding CAD/CAE/CAM fundamentally changed the way of traditional product development and manufacturing method, improved production efficiency, the quality of products and competitiveness of interprises.
The model was reconstructed based on the real multi-purpose horn wear shelf. Appropriate injection mold was designed based on PRO/E. First, the technological characteristics of the multi-purpose horn wear shelf were analyzed, including material properties, the process of the structure, forming characteristics and conditions, and the forming equipment were selected. Then the parting line was selected, the number of cavity and layout were determined. A specific introduction was made on the gating system, the cooling system, the forming parts and the stripping institutions. Then the standard mould bases were selected, and checked the technological parameters of the forming equipment. On this basis, this paper also tells about how to use the Mastercam to complete the simulation processing of multi-purpose horn wear shelf.
