ABSTRACT

 
It is to design the holder injection mould, references to the traditional mechanical design, focus on the CAD/CAM application in the plastic mould design, that is to say to apply the CAD system in model and plastic injection mould design. This artic introduces the mould technology and the CAD/CAM application of mould in china nowadays. Including AUTOCAD，MASTERCAM. While main mechanical designs content the principle and application of the plastic mould, design standards. The calculation of the plastic mould design concerns about the mould construction design, choosing Injection Molding Machine, injection system ,the move mould, immobility mould, the irrigating system, the doffing mould organ, the goring organ, the cooling system’s design and so on.
The structure designed in such way can ensure the reliable running of the mould.
