The granary side face plate air hole pressing die comprises a male die roller and a female die roller, an extrusion protruding block is arranged on the surface of the male die roller, one side of the extrusion protruding block is an opening face of a vertical plane, and the other side of the extrusion protruding block is an extrusion face of a slope face with the height gradually reduced. The extrusion convex blocks are uniformly distributed on the surface of the convex mold roller, and the specific distribution condition is set according to machining requirements; a groove is formed in the surface of the concave die roller and matched with the extrusion convex block, during machining, the concave die roller and the convex die roller are close to each other and synchronously and reversely rotate, and at the moment, the extrusion convex block on the close side of the concave die roller and the convex die roller is embedded into the groove. And the plate is extruded in a rolling manner, so that the waterproof a
