摘要： A die casting insert for producing die casted metal parts from liquid metal. The die casting insert has an outer casing shaped to be fixed in the die block of the die casting apparatus. The die casting insert also has a stopper with a purge opening that is adapted to evacuate contaminants topping the liquid metal as pressure is applied to the liquid metal. The stopper, fitted to mate with the hollow inner cavity of the injection sleeve, is constructed to seal the hollow inner cavity of the injection sleeve except at the purge opening when in a first position; and to permit the flow of the liquid metal into at least one molding cavity when the stopper is in a second position. The die casting insert also has an activation mechanism configured to shift the stopper between the first position and the second position.

摘要： A piston of a die-casting apparatus comprises: a piston head fabricated of a first material; an elongate, inner carrier coupled to the piston head; a generally annular body seated on the carrier adjacent the piston head; and a wear ring disposed on the piston head, the wear ring being fabricated of a second material. The first material has a higher toughness and a lower hardness than the second material.

摘要： A die casting system includes a die including at least one die component that defines a die cavity, a spar received within a portion of said die cavity, a shot tube in fluid communication with the die cavity, and a shot tube plunger moveable within the shot tube to communicate a molten metal into the die cavity to cast a hybrid component. The spar establishes an internal structure of the hybrid component, and one of the internal structures and an outer structure of said hybrid component is an equiaxed structure.

摘要： A method for die casting a hybrid component includes defining a cavity within a die element of a die and inserting a spar into the cavity. Molten metal is injected into the die element. The molten metal is solidified within the cavity to cast the hybrid component. The spar establishes an internal structure of the hybrid component. The spar includes a high melting temperature material that defines a first melting temperature greater than a second melting temperature of the molten metal.
