1. A die-casting machine comprising a first fixed vertical plane supporting a fixed half-die, a second fixed vertical plane longitudinally spaced apart from the first fixed vertical plane, a movable vertical plane carrying a movable half-die, placed between the first and second fixed vertical planes and horizontally translatable on command towards the first fixed vertical plane for coupling the fixed half-die and the movable half-die, and horizontal columns, wherein each horizontal column extends longitudinally along a respective column axis between a first end secured to the first fixed vertical plane, and a second end, secured to the second fixed vertical plane, and slidably supporting the movable vertical plane, wherein, at said first end, the horizontal column has a shaped section for connection to the first fixed vertical plane, the shaped section comprising a plurality of circumferential ribs radially projecting and axially spaced apart, interspersed with grooves, wherein, for each horizontal column, the die-casting machine comprises a connecting device adapted to be rigidly coupled to the shaped section of the horizontal column, forming an abutment that opposes an extraction of the horizontal column from the first fixed vertical plane, said connecting device comprising a shell rigidly coupled with shape coupling to the shaped section of the horizontal column, wherein the shell consists of two half-shells, each in the form of a hollow half-cylinder, coupled together by a plurality of tangential screws, wherein each groove of the shaped section has a substantially trapezoidal profile, wherein said substantially trapezoidal profile has a first side consisting of a truncated cone surface coaxial with the column axis, a groove bottom consisting of a cylindrical surface coaxial with the column axis and a second side consisting of a further truncated cone surface coaxial with the column axis, so that said first and second sides converge towards the column axis, and wherein each side of the substantially trapezoidal profile is inclined with respect to a direction transverse to the column axis by an angle between 6 and 16 degrees.
