摘要:
In the process according to the invention, it is proposed that a divided quantity of molten glass required for manufacturing moulded glass articles by the press process should be fed into a press mould before insertion of the die while the press mould is in the press station and the moulded glass article should be removed from the press mould after the die has been withdrawn while the press mould is still in the press station. With this process, it is possible to dispense with a mould conveyor. The invention also concerns a device suitable for carrying out said process, in which the die (29) can pivot sideways from its starting position outside the press mould (22) about an axis which is perpendicular to the central axis (M') of the die (29).

The invention concerns a method of producing glass mouldings in a press in which the punch remains, after the pressing operation, in contact with the moulding in the mould until the parts of the moulding near the surface have cooled to a temperature such that the moulding is at least temporarily rigid enough to be removed from the mould. In order to avoid the parts of the moulding near the surface warming up again and producing undesirable deformations, the moulding is transferred to a cooling station after removal from the mould. This method minimizes the dwell time of the moulding in the mould, so that the mould is ready in a very short time for another pressing operation. The method proposed thus increases the output of the press. The invention also concerns a press which is particularly suitable for use with this method, the drive to the press punch being provided by a cam driven by an electric motor with torque and rpm control.
