Manufacturing method and molding apparatus of the rare earth metal-based sintered magnet

Prepare a slurry containing the alloy powder and a dispersion medium containing a rare earth element, And accessible away from each other by at least one of movement, position the punch and lower punch above having an exhaust hole, at least one of discharging the dispersion medium of the slurry, each of the plurality of through holes provided in the mold to, a cavity surrounded by said upper punch and the lower punch and the die to a plurality preparation, Within each of said plurality of cavities, after at least one of the upper punch and the lower punch has a magnetic field is applied by the electromagnet in a direction substantially parallel to a direction movable, from the outer peripheral side surface of the mold of the plurality of cavities via a plurality of slurry supply passage extending without branching to each supplying the slurry within each of said plurality of cavities, While applying the magnetic field, the upper punch and to approximate the lower punch, obtain a compact of the alloy powder within each of said plurality of cavities, a method for producing a rare earth-based sintered magnet.
