An air set molding apparatus configured to form a sand mold, the apparatus includes a pattern mounting plate including an ejection pin aperture, a molding flask on the pattern mounting plate, the molding flask having a closed lower end and an open upper end. The molding flask including an ejection pin aperture in the closed lower end, an ejection pin movable relative to the pattern mounting plate and the molding flask, the ejection pin movable through the ejection pin aperture of the pattern mounting plate and the ejection pin aperture of the molding flask between a lowered position and a raised position. As the ejection pin moves from the lowered position to the raised position, the ejection pin lifts the sand mold through the open upper end of the molding flask.
