ABSTRACT:
The sand-metal ratio of a mold used for casting a crank shaft or cam shaft having discrete shapes is reduced to make the mold more compact. Basic discrete cavities (15) including cavities (6) corresponding to one half of shaft portions and cavities (7) corresponding to one half of cam portions are staggered by axially offsetting them in horizontal and/or vertical direction.
