INJECTION MOLDING MACHINE

PROBLEM TO BE SOLVED: To provide an injection molding machine which can be enhanced in the uniformity of a mold clamping force with a multipolar electromagnet.SOLUTION: The injection molding machine includes; a first fixing member 11 on which a fixed mold 15 is mounted; a first movable member 12 on which a movable mold 16 is mounted; a second movable member 22 which moves together with the first movable member 11; a second fixing member 13 which is arranged between the first movable member 12 and the second movable member 22; and a rod 39 which penetrates through the second fixing member 13 to connect the first movable member 12 to the second movable member 22. One of the second fixing member 13 and the second movable member 22 attracts the other member to hold a plurality of coils 48A to 48D of an electromagnet 49, which generate a mold clamping force. A plurality of current passages 81A, 81B which are symmetrically arranged about the center line 40 of the rod 39 and include a coil group comprising a plurality of coils connected in series are connected in parallel.
