    摘要: A plastic magnet injection molding machine comprising a pair of exciting coils respectively embedded into a fixed plate and a movable plate along with respective seats and a metal mold including ferromagnetic central members and non-magnetic peripheral members is provided. With such an arrangement, the machine can anisotropically process magnet powder with enhanced efficiency by energizing the coils. Both the fixed plate 2 and the movable plate 4 of the machine are made of ferromagnetic metal. The exciting coils 7, 8 are respectively embedded into the plates at the oppositely disposed sides thereof along with the non-magnetic annular seats 9, 10 surrounding the respective exciting coils. The fixed mold 12 and the movable mold 13 of the metal mold 11 of the machine include respective central members 14, 15 made of ferromagnetic metal. The central members 14, 15 of the fixed and movable molds are respectively made to abut corresponding central portions 2a, 4a of the fixed plate 2 and the movable plate 4. The fixed 12 and the movable mold 13 of the metal mold 11 also include respective peripheral members 16, 17 secured respectively to the annular seats 9, 10 to anchor the metal mold 11 to the plates.
