Through to the workpiece craft analysis, has determined the craft plan. And has designed set of true things compound molds. Uses the reference during the design, has determined each work components size. And many considerations mold structure adjustment, easy replacement and mold cost. Meanwhile has blended together the ramming mold different processing method in the mold design content, the processing craft and the assembly craft, to begins studies the ramming mold mold designer to have the certain reference value. This design designs from the mold to the spare part processing craft as well as the assembly craft and so on carries on the detailed elaboration, and carries on each important components using CAD the design. Key words: the compound mold.
