PROBLEM TO BE SOLVED: To provide an injection molding machine wherein in a mold clamping device, a mold opening and closing operation and a mold clamping operation can be performed surely, smoothly, and rapidly, and in an injection device, a simple and compact assembly can be formed and an injection molding can be achieved properly and rapidly. SOLUTION: A first cylindrical linear motor 54, as a mold clamping means, is disposed for a mold clamping device 40 and also a second cylindrical linear motor 56, as a mold opening and closing drive means, is disposed. In an injection device 60, a rotation type hollow axis motor 70 comprising a servomotor, as a drive means for measuring resin raw material, is provided on an extended axis of a screw 68. And an injection bracket 66 is fitted on guide axes 74 for supporting the motor 70 so as to be movable back and forth, and a cylindrical linear motor 78 for moving the screw 68 back and forth, which is an injection drive means, is disposed at the insertion part of the axes 74 and the bracket 66. |
