The slider 8 is connected to a motor 17 for driving the cam 6 to rotate. A connecting rod 5 is arranged between the positioning hole 16 and the piston rod 4, and different positioning holes 16 correspond to connecting rods 5 with different lengths. The length of the connecting rod 5 is different, and the filling amount of the injection is also different, but the change belongs to a tiny adjustment. The cylinder 9 is arranged at one end of the sliding block 8, and the movable end of the cylinder 9 is connected with the sliding block 8 and used for driving the sliding block 8 to slide up and down. The distance between the sliding block 8 and the injection cylinder 1 is adjusted by the air cylinder 9, and the filling amount of the injection can be adjusted corresponding to the length of the adjusting connecting rod 5, and the adjustment belongs to large-scale adjustment.
