<p>The invention provides an injection molding machine, wherein the uniformity of the clamp force based on a multipole magnet is enhanced. The injection molding machine is provided with the components as following: a first fixing compoment (11), which is provided with a fixed mold (15); a first movable component (12), which is equipped with a movable mold (16); a second movable component (22), which moves with the first movable compoment together; a second fixed compoment (13), which is arranged between the first movable compoment and the second movable compoment; and a rod (39), which passes through the second fixed compoment to connect the first movable compoment with the second movable compoment. One of the second fixed compoment and the second movable compoment absorbs the other to generate a plurality of coils (48A to 48D) of the magnet (49) of the clamp force. A plurality of current paths (81A, 81B) are in parallel connection, and a plurality of coils are in series and arranged symmetrically with the center line of a rod (40) as the center to form a coil group.</p> |
