Abstract
A method of casting a core includes the steps of preparing a first half of a corebox, preparing a second half of a corebox such that the parting line of a core formed from the first and second coreboxes runs along the vertical axis of the core.
Claims17
A railcar coupler knuckle comprising:
- a C-10 pin hole;
- and
- a top knuckle pulling lug,
- wherein interior spaces of the railcar coupler knuckle are formed using a core comprising:
- a rear core support configured to support the core when the core is assembled in a mold used to cast the railcar coupler knuckle;
- a C-10 portion configured to form the C-10 pin hole in the railcar coupler knuckle;
- at least a part of the C-10 portion begin formed as a substantially curved portion having a curved cross-section;
- a contoured surface configured to provide detail to the interior spaces of the railcar coupler knuckle;
- and
- a parting line defined on the contoured surface along a vertical direction of the core, wherein the vertical direction is a direction extending from the rear core support to the C-10 portion, and;
- the parting line substantially bisects the curved cross-section of the part of the C-10 portion being formed as the substantially curved portion,
- wherein the railcar coupler knuckle has a wall thickness that has a substantially constant thickness over a majority of the distance from the top of a front face of the top knuckle pulling lug to a bottom face of the top knuckle pulling lug.
