Abstract:
1. A method for casting at least one thrower for a railcar coupler, comprising: creating a mold box that is vertically parted in halves, each half defining respective sides of two thrower cavities and that includes: at least a portion of a sprue at a location above the thrower cavities; and an ingate connected between the sprue and one of the two thrower cavities, the thrower cavities also being oriented vertically; pouring molten metal into the mold box through the sprue and into the thrower cavities while the mold is oriented vertically, such that the molten metal passes through each of the ingates into respective hubs of the two thrower cavities, to cast the two throwers simultaneously; and shaking out the mold box to release the at least one thrower after the at least one thrower has cooled.
