Abstract
This text mainly narrates the design of injection mould for a safety helmet, including the selection of product material and its property analysis, the selection of injection machine, the design of feed system, shaping part, cooling system and core pulling, etc. Besides this, it also covers the CAD/CAM for the mold cavity, and generating G-Code instructions for CNC machine by the advanced software. In this text, the author emphasizes the use of modern computer assisted design and manufacturing technology, and apply some famous software, such as Pro/E, CAXA, to design. Through this, it not only guarantees the performance, but also raises working efficiency greatly and shortens the production cycle.
Key Words: safety helmet; injection mould; CAD/CAM.
