摘要: A conveying device for molten metal in an injection die casting unit, has a storage container for the molten metal and a conveying duct delivering the molten metal to a mold cavity. The conveying duct includes a cylinder bore with a piston disposed in an axially adjustable manner. A collection chamber, from which the molten metal is introduced through an onward line into the mold cavity upon axial displacement of the piston, is provided for the molten metal. An annular space, which is connected via at least one filling bore to the collection chamber, is formed between the outer wall of the piston and the inner wall of the cylinder bore. The filling bore, on an end which opens into the collection chamber, is closable by means of a valve body which is connected to an adjustable valve rod which is displaceably disposed in an axial bore of the piston.
