    摘要: 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.

    摘要: A method for manufacturing a railcar coupler knuckle includes, before casting, positioning an external chill within a cope mold portion and a drag mold portion offset from and adjacent internal walls of a pulling face and a throat of the cope and drag mold portions, thus producing a casting with reduced micro-shrinkage in at least the throat, a high-stress section of the casting. Use of subsurface chills produces an improved surface with fewer inclusions when compared to an equivalent surface produced in a process without use of a subsurface chill. The external chill may be a cone chill of a larger size to improve cooling and solidification at and below the surface. The external chill may also be a cylindrical and/or oblong chill with a tapered design that may correspond to the internal walls of the cope and drag mold portions between the pulling face and the throat.
