<p>A mold-closing device, particularly for die-casting machines and injection-molding machines for metals and plastics, with a stationary mold-carrier plate mounted on columns, a stationary end plate, a mold-carrier plate movable between these stationary plates from a mold-open position to a mold-closed position, a pressure piece between the mold-carrier plate and the end plate, a pressure box or hydraulic intensifier mounted on the pressure piece for producing the closure pressure and for connecting the end plate with the movable mold-carrier plate only during the casting on injecting operation, at least two piston- and- cylinder units acting between the movable mold-carrier and one of the stationary plates, and a thrust plate transversely slidable on the end plate so as to cover and uncover an aperture provided for the passage therethrough of the pressure piece, the pressure piece including a threaded sleeve or nut and a threaded spindle or ram.</p> |
