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.

摘要： A method for casting a thrower for a railcar coupler includes creating a mold box that is vertically parted in halves, each half defining a side of a thrower cavity and that includes at least a portion of a sprue at a location above the thrower cavity, the thrower cavity also being oriented vertically; pouring molten metal into the mold box through the sprue and into the thrower cavity while the mold is oriented vertically; and shaking out the mold box to release the thrower after the thrower has cooled. Creating the mold box may be executed through a cold shell process. The halves of the mold box may include reflective images of the sides of two thrower cavities and an ingate connected between the sprue and one of the two thrower cavities.

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 method for manufacturing a railcar coupler knuckle, said method includes providing a cope mold portion and a drag mold portion. The cope and drag mold portions have internal walls that define at least in part perimeter boundaries of a coupler knuckle mold cavity. At least one chill core is positioned within one of the cope mold portion and the drag mold portion. The cope and drag mold portions are closed, with the at least one core therebetween, and the closed cope and drag mold portions and the chill core define a parting line. The mold cavity is filled with a molten metal, which solidifies after filling to form a casting. The casting includes a pulling face portion defined by the chill core, and a central section of the pulling face portion does not contain the parting line and requires no finish grinding upon its formation.
