System and method for manufacturing railcar yokes

摘要

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.

1. A method for manufacturing railcar yokes, comprising:
providing a cope mold portion, the cope mold portion having internal walls defining at least in part perimeter boundaries of at least two upper yoke mold cavities; providing a drag mold portion, the drag mold portion having internal walls defining at least in part perimeter boundaries of at least two lower yoke mold cavities; positioning a slab core within the drag mold portion, the slab core 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; closing the cope and drag mold portions with the slab core therebetween; and at least partially filling the at least two upper and at least two lower yoke mold cavities with a molten alloy, the molten alloy solidifying after filling to form a first yoke, a second yoke, a third yoke, and a fourth yoke.
