1. A low-pressure die-casting apparatus comprising:
- at least one flowing furnace;
movement guides;
at least one handling unit movable on said guides for cooperating with said at least one flowing furnace;
casting dies, said at least one handling unit being selectively connectable to a respective one of said dies and movable with horizontal translatory motion on said guides between a casting position, which lies above said at least one furnace, and a discharge position; and
lifting-lowering means for moving said at least one furnace vertically with respect to a ground level in order to couple and uncouple to said respective die connected to said at least one handling unit, said lifting-lowering means comprising female threads rigidly coupled to said furnace in a downward region thereof, and respective threaded legs, fixed at the ground level, which are coupled to said female threads.

Abstract
The apparatus comprises at least one flowing furnace with which at least one handling unit cooperates, the handling unit being selectively connectable to a respective die. The at least one handling unit is associated with a guide for horizontal translatory motion between a casting position, which lies above the at least one furnace, and a discharge position. The at least one furnace can move vertically in order to couple and uncouple with respect to the corresponding die connected to the at least one handling unit.
