Abstract: Two-plate metal-die-casting machine (1), comprises a stationary part, on which a first tool clamping plate (5) is arranged in a fixed manner and a movable part, on which a second tool clamping plate (6) is arranged, which is movably guided towards columns (8), where one half of a interchangeable metal-die-casting mold (20) is accommodated on each tool clamping plate, and a metal-melt transporting device in communication with the two tool clamping plates for loading the interchangeable die-casting mold with molten metal, where the melt transporting device includes e.g. a melt chamber. Two-plate metal-die-casting machine (1), comprises a stationary part, on which a first tool clamping plate (5) is arranged in a fixed manner and a movable part, on which a second tool clamping plate (6) is arranged, which is movably guided towards columns (8), where one half of a interchangeable metal-die-casting mold (20) is accommodated on each tool clamping plate, and a metal-melt transporting device in communication with the two tool clamping plates for loading the interchangeable die-casting mold with molten metal, where the melt transporting device includes: a melt chamber, extending in the melt conveying direction, which comprises an inlet opening for the metal-melt in an end portion and the inlet opening of the interchangeable die-casting mold for the metal-melt is at least partially covered with an outlet opening in a further end portion; a first piston associated with the stationary part of the die-casting machine, which is slidably guided into the melt chamber; and a second piston arranged on the side of the melt chamber, which is opposite to the first piston and is associated with the movable part of the die-casting machine, where the second piston is slidably guided into the melt chamber. The end surfaces of the two pistons are facing each other. The first piston and the second piston temporally controlled in the melt chamber via a control unit are independently displaceable from one another. The melt transporting device as a module of the die- casting machine is couplable to the respective interchangeable die-casting-mold. An independent claim is also included for the metal-melt transporting device for mounting in the two-plate-metal-die-casting machine, comprising (a) the melt chamber including the inlet opening for the metallic melt at one end portion and the outlet opening arranged in a coupling region of the melt transporting device arranged, in which the die-casting mold is attachable, (b) the first piston slidably guided into the melt chamber, which is assignable to the fixed-stationary part of the die-casting machine, and the second piston, which is arranged on the side of the melt chamber, which is opposite to the first piston and is assignable to the movable part of the die-casting-machine, (c) the end surfaces of the two pistons that are facing each other, and (d) the first piston and the second piston, which are independently displaceable from one another in a controlled manner in the longitudinal direction of the melt chamber.
