Patent ID: 8066498

Claim:
A magnetic field molding device used in producing a ferrite sintered magnet, comprising: a die for compression-molding a molding slurry, wherein the slurry is produced by dispersing a powder mainly composed of ferrite in a dispersion medium and injected into the die, a magnetic field generating source for applying a magnetic field to the slurry within the die in a given direction, a delivery path provided in the die for injecting the slurry into a cavity for forming the ferrite sintered magnet, a heater provided under the cavity for heating the slurry flowing in the delivery path, a controller for controlling the heater, and a mortar shaped die cooperatively forming a portion of said die, said mortar shaped die having a bottom and a separate block member that may remain fixed to the bottom throughout a plurality of molding cycles, said heater and delivery path being provided in said block member with said heater being positioned along said delivery path.
