6. The method for operating the automatic cutting device for the injection mold according to any one of claims 1 to 5, characterized in that: The specific steps include: S1. After the plastic parts inside the molding seat (7) are molded by injection molding, the cylinder (10) is started to drive the sealing seat (12) to move rightward through the movable plate (11). During the movement of the movable plate (11) to the rightward, the connecting rod (83) is pulled downward by the pull rope (811), thereby driving the cutting blade (82) to move downward, so that the acute angled surface (812) below the cutting blade (82) can cut the glue port, so that the glue port can fall onto the drag reduction layer (17) on the guide plate (15); S2, then start the double-axis motor (92), and then drive the rotating disk (94) to rotate through the driving shaft (93), and then drive the entire counterweight block (96) to rotate, and cooperate with the spring rod (3) to make the entire vibration seat (2) vibrate up and down, and then drive the guide plate (15) to vibrate, so that the waste on the top can slide down, and at the same time, driven by the transmission shaft (971), the moving disk (972) rotates rapidly, and then cooperates with the pulling rod (977) and the connecting block (976) to drive the disc (974) to reciprocate up and down, and at the same time drive the sealing ring (975) upward. The disc (974) reciprocates downward. When the disc (974) moves upward, the external air enters the inside of the air charging pipe (9710) through the air suction pipe (9711) and the air suction valve (9713), and then enters the air drum (973). When the disc (974) moves downward, the air inside the air drum (973) enters the cross pipe (978) through the air charging pipe (9710) and the air charging valve (9712), and is sprayed toward the drag reduction layer (17) through the nozzle (979), so that the waste can fall faster and avoid blockage. All the waste is concentrated in the recovery box (14).

7. The method for operating the automatic cutting device for the plastic port of an injection mold according to claim 6, characterized in that: The counterweight (96) in step S2 is a lead block.
