Casting process for railcar coupler throwers |
摘要 |
A method for casting a thrower for a railcar coupler includes creating a mold box that is vertically parted in halves, each half defining a side of a thrower cavity and that includes at least a portion of a sprue at a location above the thrower cavity, the thrower cavity also being oriented vertically; pouring molten metal into the mold box through the sprue and into the thrower cavity while the mold is oriented vertically; and shaking out the mold box to release the thrower after the thrower has cooled. Creating the mold box may be executed through a cold shell process. The halves of the mold box may include reflective images of the sides of two thrower cavities and an ingate connected between the sprue and one of the two thrower cavities. |
