In a horizontal pressure die-casting machine having two fixing plates, each for one die the invention comprising a one of the fixing plate being pivotable into a horizontal position about a horizontal axis, and assembled of two parts, namely a base plate and a mounting plate. In the horizontal position, the die to be carried by the mounting plate and, provisionally, also the die to be carried by the stationary fixing plate can be exactly mounted and a cast produced can easily be removed. To take up the strong pressing forces occurring during a casting operation, the movable fixing plate which is pivoted back into its vertical position, is mechanically locked to the fixing plate, and the die to be carried by the latter is transferred thereto for final securing. The mounting plate is mounted on the base plate for being hydraulically displaced relative thereto by means of piston-and-cylinder units so that with the base plate locked in its vertical position, the mounting plate 6 can be moved toward the stationary fixing plate and the mold can be brought into its closed operating position.
