Abstract
In manufacturing a magnet embedded core, creation of flash, and problems associated with flash are prevented. A device for manufacturing the magnet embedded core comprises a base () comprising an upper surface at which a resin pot chamber () for storing molten resin opens, a separator plate () detachably placed on the upper surface of the base () to support a rotor core () thereon and having a gate () and a cull opening () communicating the magnet insertion hole () of the rotor core () with the resin pot chamber (), and a plunger () movably provided in the resin pot chamber () to press the molten resin in the resin pot chamber () into the magnet insertion hole () via the gate () and the cull opening (), wherein an annular recess () is formed on the upper surface of the base () so as to extend outward of the resin pot chamber () and communicate with the resin pot chamber ().
