The invention discloses a waste material ejecting-out mechanism and a stamping die. The waste material ejecting-out mechanism comprises a driving unit, a first-level material supporting frame and a second-level material supporting frame, wherein the driving unit is suitable for being installed on a die holder; the first-level material supporting frame is connected with the driving unit; the second-level material supporting frame is hinged to the first-level material supporting frame around the rotating axis; the gravity action line of the second-level material supporting frame does not pass through the rotating axis; the second-level material supporting frame is arranged to be lower than the first-level material supporting frame during die closing of the die; and when the driving unit is lifted to the extreme position, the second-level material supporting frame rotates to be partially higher than the first-level material supporting frame under the gravity effect. By means of the wastematerial ejecting-out mechanism, the total ejecting-out stroke of the waste material ejecting-out mechanism can be prolonged, the space of the stamping die is saved, it is guaranteed that a waste material slides and falls stably, and the operating safety and the stamping production efficiency are greatly improved.
