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. In molding in a magnetic field, the mortar-shaped dieprovided with a plurality of the cavitiesis heated by the heater member, provided in the heater block located under the mortar-shape die, under control of a controller at varying temperature depending on the position of the mortar-shape die, to keep uniform temperature of the slurry in the cavities. This assures good and stable slurry dehydration properties and improves product yield.
