The Research And Development Of Compression Moulding CAD/CAM System

In this paper, to begin with, the principles and implement of compression moulding CAD are expounded, also the whole structure and embodying methods of this system are mainly dissertated, and the implement on compression moulding CAD and mould structure CAD are analyzed in detail. The compression process CAD mainly included primary contents as following: compression part process judging, shaping force calculation, hydropress selection, opening die force and knockout press calculation, checking the working stroke of hydropress, heat calculation and heat rod selection. The mould structure CAD included: assembly design, punch design, die design, transfer chamber design and calculation, punch and die with transfer chamber mating, slide loose core design, standard parts management, non-standard parts management, drawing output. Secondly, based on the CAD, CAM research is briefly studied in this paper. Finally, the shortcomings and improvements are mentioned.
