磁場成形装置、フェライト磁石の製造方法、金型
Document Type and Number:
Japanese Patent JP4798372
Kind Code:
B2
Abstract:
The objects of the present invention are to provide a magnetic field molding device capable of improving yield in a production and stabilizing product quality, and a method for producing a ferrite magnet. Inmoldinginamagneticfield, the mortar-shaped die 19 provided with a plurality of the cavities 13 is heated by the heater member 20, provided in the heater block located under the mortar-shape die 19, under control of a controller at varying temperature depending on the position of the mortar-shape die 19, to keep uniform temperature of the slurry in the cavities 13. This assures good and stable slurry dehydration properties and improves product yield.
