ABSTRACT:
A gooseneck assembly (10) for hot chamber die-casting comprises a shot cylinder (12), an injection duct (16) leading from the bottom of the cylinder to a die (18), and a reservoir (20) which communicates with the shot cylinder through openings (22, 23 and 24) in a partition wall (21). The upper ends of the shot cylinder and reservoir are closed and a protective atmosphere is maintained above a level (6A) of molten metal in the assembly. The assembly is automatically recharged with molten metal from a separate crucible (3) through a syphon pipe (30).
