Abstract
A molding tool (10) for manufacturing cooling features in a ceramic core for a casting process includes a first mold portion (12) comprising a crossover hole forming feature (18); a second mold portion (24) comprising an impingement jet receiving forming feature (30) for forming an impingement jet receiving feature having a desired aiming point (32); and a sacrificial alignment member (34) for extending at least partially into the crossover hole forming feature (18) at least partially into the aiming point (32) of the impingement jet receiving forming feature (30) for substantially aligning a central axis (38) of the crossover hole forming feature (18) with the aiming point (32) to maintain a crossover hole and aiming point alignment during casting to ensure that the jet is directed at the aiming point (32) in a resultant cast part.
