摘要： A casting apparatus for casting a railcar coupler, which includes a shank portion and a head portion, includes cope and drag portions that define an external shape of the coupler. The casting apparatus also includes one or more cores that define an interior of the shank portion and a separate head core with an exterior that defines an interior of the head portion that includes lock chamber, guard arm side portion, and knuckle side portions of the head. The head core is a single piece with a hollow center section that defines a front face gating system that includes at least one in-gate configured to direct molten material to top and bottom regions of the head to define the lock chamber, guard arm side portion, and knuckle side of the head.

摘要： A casting assembly for manufacturing a lock of a railcar coupler includes drag and cope portions of a first mold that defines exterior surfaces of the lock, wherein the first mold comprises a first molding material. The casting assembly also includes a second mold formed of a second molding material. The second mold defines a cavity with an interior surface that substantially complements an exterior surface of the first mold. A down sprue is formed in the second mold. A gating system is formed in the second mold that and is in fluid communication with the down sprue. An in-gate is formed in the second mold and is in fluid communication with the gating system and the first mold.

摘要： A main body core box assembly for creating coupler head cores which are attachable to various shank cores includes a main body core box including two halves, each half including a pattern configured to form the outer walls of a first head core having a first shank core. A plug is insertable into an end of respective patterns to form a second, alternative head core having a first half of a connection joint attachable to a second shank core that includes a second half of the connection joint, the second shank core being different than the first shank core. The first half of the connection joint may be a male connector, where the plug includes a recess having an angled surface to create a notch on the male connector. The second half of the connection joint may be a female connector with a raised surface corresponding to the notch.

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.
