DEVICE FOR LOCKING AND EXTRACTING A CENTRIFUGAL CASTING SHELL AND REMOVING THE CAST PART FROM THE SHELL

摘要

Device for locking a shell in, or extracting the shell from, a sleeve of a centrifugal casting machine for casting tubular parts. The device has tong means for extracting the part which are connected to an extracting carriage movable in the axial extension of the sleeve. Locking means for locking the shell in the sleeve are combined with a head having a flange and connected to move axially with the shell. Hooking members pivotably mounted with respect to the carriage cooperate with the flange and are adapted to exert a push or a pull on the head and shell for respectively locking or unlocking the shell. The extracting carriage also carries counter-support abutments for the sleeve.
