Abstract
An injection mechanism for an injection molding machine includes a front plate carrying an injection cylinder. A guide rod is arranged fixedly relative to the front plate, and defines a longitudinal guiding axis. A movable plate is arranged movably relative to said front plate along said guiding axis, and carries an injection screw. A support structure is interposed between the guide rod and the movable plate, and movably supports the movable plate on the guide rod along the guiding axis. The support structure including a ball-engaging surface is provided on the guide rod and a ball-spline nut is provided in the movable plate. The ball-spline nut is engaged with the ball-engaging surface.
