Abstract
The valve assembly for venting die casting molds includes a venting channel, a venting valve communicating with the venting channel, as well as an actuating device for closing the venting valve. The actuating device includes a power pick-up member that is axially movable under the influence of the liquid casting material entering the venting channel. The venting valve includes a closure member biased against a stop member and operatively connected to an actuating element. The stop member is pivotable by the power pick-up member such that the closure member of the venting valve is displaced from its open position to its closed position under the influence of the actuating element. Thereby, a reliable closing of the venting valve is ensured, even under unfavorable operating conditions.
