A method for manufacturing railcar yokes includes providing a cope mold portion having internal walls defining at least in part perimeter boundaries of at least two upper yoke mold cavities. The method further comprises providing a drag mold portion having internal walls defining at least in part perimeter boundaries of at least two lower yoke mold cavities. A slab core is positioned within the drag mold portion. The slab core is configured to define at least in part perimeter boundaries of the at least two upper yoke mold cavities and the at least two lower yoke mold cavities. The cope and drag mold portions are closed with the slab core therebetween. The method also comprises at least partially filling the at least two upper and at least two lower yoke mold cavities with a molten alloy to form a first, second, third, and fourth yoke.

System and method for manufacturing railcar yokes

A metal casting riser sleeve system includes a cope mold portion and an outer riser sleeve portion positioned in the cope mold portion. The outer riser sleeve portion encloses a central outer riser sleeve portion passageway between an outer riser sleeve portion bottom end and top end. The system also includes an inner riser sleeve portion that forms a central inner riser sleeve portion passageway between an inner riser sleeve portion bottom end and top end. The inner riser sleeve portion is slidably positioned within the outer riser sleeve portion passageway. The inner riser sleeve portion is operable to slide upward such that the inner riser sleeve portion top end is above the outer riser sleeve portion top end and such that a riser sleeve system passageway is formed between the inner riser sleeve portion top end and the outer riser sleeve portion bottom end.
