ABSTRACT:
Provided is an injection molding machine using a built-in type motor as a measuring electric servomotor. In order to reduce the entire length of the machine (the injection molding machine), the metering electric motor is exemplified by a hollow built-in type motor, which includes a cylindrical stator, and a cylindrical rotor positioned in the stator. A sleeve is fixed in the rotor of the built-in type motor, and a member fixing the rear end portion of a screw and the sleeve are connected/fixed. Moreover, a nut member as a straight portion of a ball screw mechanism for converting the rotation of an injecting electric motor into linear motions and the sleeve are connected/fixed.
