摘要： A valve assembly for venting diecasting moulds comprises a venting channel, a venting valve communicating with the venting channel and having an axially displaceable valve closure member, and an actuating member for operating the venting valve from an open position into a closed position. The actuating member includes a power pick up member exposed to the liquid casting material escaping during the casting operation from a casting chamber provided in the diecasting mould through the venting channel and being axially displaceable under the influence of the kinetic energy transmitted from the liquid casting material to the power pick up member when the liquid casting material hits the power pick up member. The power pick up member is mechanically coupled to the axially displaceable valve closure member and includes an axially displaceable push member having an operating stroke whose length is limited to only a fraction of the length of the stroke performed by the axially displaceable valve closure member when it is driven from its open position to its closed position. The axially displaceable valve closure member freely moves along a path in addition to the operating stroke of the power pick up member. The actuating member further comprises a power transmission member for the transmission of the impact force exerted by the liquid casting material onto the power pick up member to the axially displaceable valve closure member of the venting valve.

摘要： In order to vent a diecasting mold of a diecasting machine, it is proposed that the mold cavity and/or the pressure chamber are vented during the filling operation by a second venting valve, additionally to a first venting valve. The first venting valve is located in a venting channel portion that communicates with a venting channel leading out of the mold cavity. For operating the first venting valve, an impact transmitter is provided that is operationally connected to the first venting valve and that is exposed to and moved by the casting material advancing from the mold cavity to the venting channel. The second venting valve is operated by separate independent means and is closed before the mold cavity is completely filled. As a criterion for closing the second venting valve, the length of the path can be used along which the casting piston runs during the filling operation.

摘要： 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.
