  • Electromagnetic coaxial driving injection apparatus
    Patent number: 7090477
    Abstract: An electromagnetic coaxial driving injection apparatus, having a linear motor for driving injection and a rotation motor for metering. The linear motor and the rotation motor of both the injection and metering motors and an injection screw are set on a common axis. A connecting device connects moving parts of the motors with the injection screw. Stationary parts of the motors are fastened on a frame and forward-backward moving unit, not moving during injection and metering. Due to the arrangement of the moving parts and the injection screw on a single axis, moving parts are lessened, and transmission losses are minimized. Since the number of structural parts is low, only the moving parts of the motors move during injection while the stationary parts thereof remain at rest, thus greatly reducing inertia.
