Abstract: A servo injection molding machine includes an injection screw, a ball screw, and a spline shaft that are mounted along the same axis. The spline shaft and the injection screw are connected by a connecting seat. An injection servomotor drives an injection sleeve mounted to a side of an injection seat, which, in turn, makes a ball nut drive a ball screw to move rectilinearly. A metering servomotor drives the spline shaft on a feeding seat to rotate in a direction that is same as or different from that of the injection servomotor or to rotate at a speed the same or not the same as that of the injection servomotor, thereby controlling the spline shaft to rotate on site or move rectilinearly for performing injection.
