The invention discloses an air blowing type waste cleaning mould which comprises a lower waste cleaning base plate for bearing die-cutting printing paper. A movable mould plate capable of moving up and down is arranged above the lower waste cleaning base plate at an interval; air blowing waste cleaning needles for pressing the die-cutting printing paper and blowing out air are fixed to the bottompart of the movable mould plate; and the air blowing waste cleaning needles, waste on the die-cutting printing paper, and waste cleaning holes in the lower waste cleaning base plate are coaxial and are in one-to-one correspondence. According to the air blowing type waste cleaning mould provided by the invention, through the air blowing waste cleaning needles capable of moving up and down, the die-cutting printing paper is pressed, the waste is blown down, and tiny waste can be synchronously and efficiently cleaned, so that the cost is reduced. 本发明公开了一种吹气式清废模具，包括用于承载模切后印刷纸的下清废基板，所述下清废基板上方间隔设有一可上下移动的动模板，所述动模板底部固定有用于压住所述
