Patent ID: 7784525

Claim:
A die casting machine for the production of casting parts from metals, and/or their alloys, comprising of: a horizontal injection plunger ( 1 ); a horizontal assistant plunger ( 3 ) positioned to face the horizontal injection plunger; an injection sleeve ( 2 ) which cooperates with the horizontal injection plunger and horizontal assistant plunger to define a closed space in which the liquid metal is loaded into; a movable mold ( 9 ) and a stationary mold ( 10 ); a cavity formed between the movable mold and the stationary mold; the injection plunger is operable to seal the cavity from the closed spaced; an intensification plunger( 12 ) which squeezes the liquid after the injection plunger seals the cavity from the closed space ( 11 ); a mold support on which the stationary mold ( 10 ) and the movable mold ( 9 ) are mounted, wherein said injection plunger, said assistant plunger and said intensification plunger are moved by a respective flow power device such as a hydraulic cylinder or a servo motor, and wherein the flow power device for moving said assistant plunger is mounded on a back plate ( 8 ), whereby it will cause no impact pressure to movable plate ( 7 ) at the end of the cavity filling of molten metal.
