The utility model discloses a bottom waste cutting device for a hollow blow molding machine, comprising a discharge support. A first clamp for clamping a bottle mouth is arranged at the bottle mouth on the discharge support, a plurality of vertical mounting frames arranged oppositely are arranged on the discharge support, a second clamp for clamping a bottle body is arranged on each mounting frame, and clamping plates arranged oppositely are arranged at the bottle bottom part and move back and forth through air cylinders. The second clamp comprises left and right fixing plates arranged oppositely, and semi-arc clamping plates are arranged inside the fixing plates. Air cylinders are arranged outside the discharge support and the mounting frames to drive the clamps to move back and forth. The bottle body is clamped by the left and right cross bars at the second clamp on the bottle body, preventing the plastic bottle from falling due to clamping only by the first clamp at the bottle mouth. The clamping plates arranged oppositely at the bottle bottom part move back and forth through air cylinders, and the air cylinders push the clamping plates to cut off the waste at the bottle bottom by external force at the clamping plates, avoiding the problems of low efficiency and low automation caused by subsequent manual breaking.
