Blanking device of injection molding machine

The utility model relates to an injection molding machine discharging device which comprises an injection molding machine body, one end of the top of the injection molding machine body fixedly communicates with a discharging tank, inclined rods are fixedly arranged at the bottoms of the two sides of the inner wall of the discharging tank, a limiting ring is fixedly arranged between the two inclined rods, a spring is fixedly arranged on the limiting ring, and a pressing plate is installed at the top of the spring. The bottom of the pressing plate is fixedly connected with a dredging rod sequentially penetrating through the spring and the limiting ring. In the embodiment of the invention, the dredging rod is elastically arranged above the discharging opening in the discharging tank through cooperation of the inclined rod, the limiting ring and the spring, when the discharging opening is blocked, the air cylinder drives the rotating rod to descend, so that the rotating rod extrudes the pressing plate, and the pr
