ABSTRACT:
A lined shot sleeve for use in injection die casting molten metal is disclosed. The lined shot sleeve comprises an elongated main body portion including a first continuous inner wall surface defining a receptacle bore axially extending between a first end and a second end of the main body portion A first ingress port opens onto the continuous inner wall surface and adapted to provide for passage of the molten metal into the receptacle bore There is an elongated ceramic liner adapted for secure placement within the receptacle bore, the liner including a second continuous inner wall surface defining a cylinder bore axially extending between a first end and a second end of the liner and an exterior wall surface adapted for frictional contact with the first continuous inner wall surface. The first and second ends of the ceramic liner are generally coincident with the first and second ends of the main body portion. A second ingress port opens onto the exterior of the liner in register with the first ingress port and adapted to provide for passage of the molten metal into the cylinder bore. The elongated ceramic liner acts as a physical and thermal insulator to protect the first continuous inner wall surface of the main body portion from contact with the molten metal. The shot sleeve further comprises an end collar member adapted for secure attachment to the first end of the main body portion and the first end thereof being adapted for operative engagement with an injection die casting mold platen.
