[0027] In view of this, the utility model provides an aluminum alloy flange mold which is convenient for blanking. Through the coordinated use of the mold, telescopic parts, guide rack, round tube, limit parts, etc., the aluminum alloy flange workpiece is put on the limit ring, and the telescopic parts are started to drive the guide rack to move upward.
