To prevent the creation of unnecessary resin from the resin used for fixing the magnet, a device for manufacturing a magnet embedded core including a magnet embedded in resin filling a magnet insertion hole (104) extending axially in a motor core comprises a resin charging device (80) configured to charge the resin (114) in solid form into the magnet insertion hole (104), a magnet insertion device (90) configured to insert the magnet (110) into the magnet insertion hole (104), and a heating device (70) configured to heat the motor core (101) to melt the resin (114) in solid form received in the magnet insertion hole (104).

An air ejector of a resin molding device includes air passages, air outlets through which air is injected, movable valves biased by bias members to close the air outlets, accommodation spaces in which the movable valves are movably contained, an air supply path through which air is supplied from an air supply source, and a pressure sensor to detect air pressure. After completing the mold removal, the air is supplied via the air supply path to the air passages at an air pressure smaller than the bias force of the bias members, and the air pressure is detected by the pressure sensor.

Moving servo motors of molds in synchronization with the operations of platens which enables fine patterns or shapes to be formed even on a large molded article. A mold clamping device forms patterns or the like on a molded article by detecting a mold position of a second platen among first, second, third platens with digital mold opening/closing position detector, and driving servo motors for molds of the molds in synchronization with a digital mold opening/closing position signal from the digital mold opening/closing position detector.
