摘要： A gas-venting valve includes a sliding valve and either a fixed or movable valve chamber. The valve is closed by impingement of molten metal or melt flowing out of a cavity defined by the mold, in such a manner that the valve is forced to move relative to the valve chamber from a first position to a second position. The invention further includes a device for urging the valve to move relative to the valve chamber from the first position to the second position; a device for restraining the valve at the first position and preventing it from moving toward the second position, against the force of the urging device, until a part of the melt impinges against the valve; and a device for actuating the valve to return from the second position to the first position against the force of the urging device.

摘要： An arrangement incorporated with a mold for use in a die casting machine or an injection mold machine comprising: a gas vent passage formed in the mold communicating with a cavity of the mold; two symmetrical by-pass passages branched from the gas vent passage; a gas discharge passage communicating with the outside of the mold; and valve means including a valve chamber formed in the mold having a valve located therein and communicating with the above-mentioned passages. The valve in a first position cooperates with the valve chamber to prevent the gas vent passage from communicating with the gas discharge passage, but prevents both the gas vent passage and the by-pass passages from communicating with the gas discharge passage when in a second position. A portion of the melt forced to flow from the cavity through the gas vent passage upon impingement of that portion of the melt against the valve drives the valve from the first position to the second position before any of the melt forced to flow through the by-pass passages reaches the valve chamber.

摘要： A gas venting arrangement incorporated into a mold for use in a die casting or injection mold machine, having a passage for venting gases including by-pass passages and a valve chamber consisting of a forward portion formed in the mold where the valve is slidably received and a rear portion formed by a member separate from the mold. The valve and the passage are designed so that the valve is forced to move from an opened position to a closed position to shut the passage upon axial impingement of a melt from a cavity of the mold. The arrangement has a first system for biasing the valve into the opened position, a second system for biasing the valve into the opened position upon the melt impingement, and a system for releasing the valve from the second biasing means to return from the opened position to the closed position. There is provided a piston-cylinder device, in which the valve and the rear portion of the valve chamber form the piston and the cylinder, respectively, which device provides the first releasing system when the piston is actuated to move forward and second system for releasing the valve from the first biasing system to move from the closed position to the open position when the piston is actuated to move rearward.
