Embodiment Construction

[0026] Referring to Figure 1 of the accompanying drawings to Figure 12 For best understanding of the exemplary embodiments and their advantages, like reference numerals are used for like and corresponding parts in the various drawings.

[0027] Rail car couplers are arranged at each end of a railroad car to enable coupling of one end of such a railroad car to adjacently arranged ends of other railroad cars. Typically, rail vehicle couplers are manufactured from cast steel or other alloys using molds and a core assembly comprising a plurality of cores. Each core can be used to form one or more interior cavities of the coupler. Traditional methods of manufacturing rail vehicle couplers have involved making the coupler using seven to eight cores positioned within a mold. These cores are usually held in place using nails and / or rings. During the casting process itself, the interrelationship of the mold and the core disposed within the mold is critical to making a satisfactory ...

Abstract

A method for manufacturing a rail vehicle coupler head core includes the steps of providing a first core box having an inner wall at least partially delimiting a peripheral boundary of at least one rotor core cavity . The method also includes at least partially filling at least one rotor core cavity with a first sand resin to form at least one rotor core. The method also includes providing a second core box having an inner wall at least partially delimiting a perimeter boundary of the at least one head core cavity. At least one rotor core is positioned within the second core box. The method also includes at least partially filling the at least one head core cavity with a second sand resin to form the at least one head core.
