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.

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 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, 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.

摘要： A method of manufacturing a railcar having an enclosing superstructure which is capable of accommodating large vehicles such as semi-trucks is disclosed. The method includes the preparation of a previously used railcar or a railcar originally manufactured for another purpose and the subsequent attachment of a preferably widened superstructure applied thereto. Usable space and dimensions within the superstructure enclosure are maximized by the use of shallow weight bearing side structures, large top chords, stabilizing door headers, an extension of the railcar deck and thin end doors. Railcar accessories are accommodated within the interior of the superstructure such that minimal useful space is used.
