A die assembly for squeeze casting an article includes a two-piece first die section including a densifying die member and a base die member and a second die section. The first and second die sections define a die cavity therebetween having the shape of an article to be cast. The die sections are movable between an open position and a closed position in which the die cavity can be filled with an accurately controlled volume of molten material. The densifying die member is movable relative to the base die member from a first position to a densifying position in which the densifying die member is spaced apart from the base die member to accurately reduce the volume of the die cavity when the first and second die sections are in their closed position and the die cavity is filled with molten material.

[ What we claim is:] [1.] A die assembly for squeeze casting an article from a molten material, comprising a two-piece first die section, including a densifying die member and a base die member, and a second die section, said first die section adapted to be rigidly secured to a first platten of a squeeze casting machine, said second die section being adapted to be rigidly secured to a second platten of a squeeze casting machine, said first and second die sections cooperating to define a die cavity having the shape of an article to be cast, said first die section and first platten being movable relative to said second die section and said second platten between an open position in which said first die section is spaced apart from said second die section and a closed position in which said first die section is disposed contiguous to said second die section to define a fill position for said die cavity wherein said die cavity can be filled with an accurately controlled volume of molten material to cast an article, said densifying die member of said first die section cooperating with said second die section to define said die cavity, said densifying die member being movable relative to said base die member from a first position to a densifying position in which said densifying die member is spaced apart from said base die member, said densifying die member when moving to said densifying position moving toward said second die section to reduce by an accurately controlled predetermined amount the volume of said die cavity when said first and second die sections are in their closed position and said die cavity is filled with molten material.
