    • The apparatus has a valve arrangement which opens rapidly due to priming or prestressing of the valve plate by the pressure in the pressure chamber. When the valve is closed, pressure, built up in the pressure chamber space closed by the valve, applies a force to the valve member in the direction of its open position. The valve member is held closed by a holder arrangement. Following the development of a predetermined pressure in the pressure chamber, the holder arrangement releases the valve member such that the pressure in the pressure chamber forces the valve member to its open position opening the pressure chamber passage and permitting the pressure medium to surge onto the surface of the molding material. This apparatus is suitable for all high-stressed gases which must be released suddenly.
    • 该装置具有阀装置,其由于压力室中的压力而引起或预加压阀板而快速打开。 当阀门关闭时,由压力室空间积聚的压力由阀门封闭,在其打开位置的方向向阀件施加力。 阀构件由保持器装置保持关闭。 在压力室中产生预定压力之后,保持器装置释放阀构件,使得压力室中的压力迫使阀构件打开压力室通道的打开位置,并允许压力介质浪涌到表面上 的成型材料。 该设备适用于必须突然释放的所有高应力气体。

    • A system for handling pattern devices in molding apparatus for producing mold halves in mold boxes includes a rotatable transfer device having a pair of diametrically opposed tables whereby rotation of the transfer device will periodically shift the tables between a waiting position and an operating position located on opposite sides of the axis of rotation of the transfer device. A conveyor track system is provided having a portion thereof defined by conveyor track elements located on the tables. The conveyor track system includes an upper track section and a lower track section and the overall conveyor track system is formed to define a closed circulation path for the pattern devices.
