Method for producing rare earth anisotropic bond magnets, method for orientation processing of magnetic molded bodies, and in-magnetic filed molding apparatus

The present invention relates to a method for producing a rare earth anisotropic bond magnet containing a hollow cylindrically shaped magnetic molded body having, at the hollow cylindrically shaped side face thereof, at least 4 or more orientation portions that are oriented with semi-radial distribution by compression molding of a magnetic material after thermally orienting step, wherein intermediate aligning magnetic fields applied in the thermally orienting step to between adjacent cavities are the mostly same in their magnetic directions. A plurality of rare earth anisotropic bond magnets can be efficiently produced at one time.
