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.

摘要： A core assembly for creating interior spaces in a railcar coupler knuckle is designed to be set in a cavity with cope and drag sections. The cavity is shaped to form a railcar coupler knuckle and includes a first wall that forms the substantially vertical outside wall of the tail of the knuckle. The core includes a kidney section with a rear core support section that extends at least 0.5″ outside the first wall of the cavity when the core is set in the drag.
