ABSTRACT:
An electric motor type injection apparatus for a vertical molding machine which is compact in size and can be installed on a square measure limited is provided. According to this apparatus, an improper movement due to self-weight of injection mechanism members can be prevented, and deviation of a nozzle tip resulting in the cause of damage of a nozzle tip and a gate can be corrected. The apparatus is constituted by an injection driving device comprising a lower plate, an upper plate, an injection plate movable freely between the upper and the lower plates, an injection driving means comprising a ball screw shaft and a ball nut, a driving source for the injection driving means provided on the upper plate, a metering driving source for rotating a screw; a moving mechanism comprising a pair of ball screw shafts and ball nuts so as that nozzle touches by moving the injection driving device upwardly and downwardly; and a movement driving source for rotating the ball screw shafts, wherein they are arranged in a special manner.
