摘要:Devices for sealing the gap between a bore pin and an insert (e.g., sleeve) during the casting of, for example, internal combustion engine cylinder blocks. Such devices incorporate a sealing ring set that may be set into a recessed channel about a circumference of the bore pin. Radial force on the ring provides a seal between the bore pin and the sleeve that prevents flash from entering gaps therebetween. The ring may take on any of a number of different configurations and the outward force may be generated in various ways—including from the tension of the ring itself.
