Definitions
- the present invention relates to a device for changing model plates in molding machines, the model plate being fed from a lifting station from a turntable or turnstile to a model plate carriage.
- a number of devices are known for changing model plates, in which the model plates e.g. are moved by a transverse movement from a storage station into the molding machine.
- Other devices are based on the principle of the turntable or turnstile, a model carrier being removed from a magazine station and exchanged for a model carrier located in the molding machine during a cycle interruption of the molding machine.
- a device which has a lifting cylinder attached to a frame, on the piston rod of which a lifting frame with vertical separation cylinders is arranged and in the model plate carrier, preferably four openings are arranged in a preferably orthogonal grid for each partial model plate , where the number and pitch of the separating cylinders match the arrangement of the openings.
- FIG. 1 It shows a schematic representation of a rotary table 1, which indicates the position of the model plate in the molding machine with a position 2.
- 3 shows the position of the model plate outside the molding machine, which corresponds to the position of a lifting station.
- the lifting station has a lifting table which can be moved in the vertical direction via a cylinder arrangement.
- the movement can be pneumatic, hydraulic or electro-mechanical.
- At the top of the lifting table are preferably arranged not shown on drivable rollers, the dimensions of which are adapted to the model plates.
- the lifting station has a lower position in which the vertical axis of the lifting station intersects the swivel circle 4 of the turntable 1.
- the upper end position of the lifting station is in the area of a feed device 5 for the model plates.
- the axis 5 of the feed device runs in the horizontal direction through the vertical axis of the lifting station.
- the feed device essentially consists of at least two model plate carriages provided with rollers, not shown. These rollers are used to hold the model plates and are driven. In order to move these model plate carriages into the area of the lifting table, displacement devices, for example thrust piston drives, are provided on the underside of the model plate carriages. The operation of the device is as follows:
- the model plate located in the lower position of the lifting station is taken over by the lifting station and moved to the height of the axis of the feeding device in the upper position.
- the two model cars are brought into the area of the upper lifting station by means of the push piston drives.
- model plate In this position, the model plate is moved from the rollers arranged in the lifting table onto the empty model car ready. At the same time, a ready-made model plate rolls onto the rollers of the lifting table via the driven rollers of the other model car. Then both model cars move back to their starting positions and the lift table is lowered into the swivel-in level of the turntable with the model plates taken over.
- the model plate in the machine can now be replaced from this position.

Abstract
Un dispositif pour changer des plaques-modèles est proposé, dans lequel l'axe vertical (7) de la station d'élévation coupe aussi bien l'axe longitudinal (5) que la circonférence de pivotement (4). Ce dispositif est utile dans la fabrication de moules en sable pour des machines à mouler en fonderie. Ce dispositif permet de changer les plaques-modèles sans interrompre la cadence en aval des machines à mouler. En outre, il permet de positionner des parties des plaques-modèles en dehors de la machine à mouler.A device for changing model plates is proposed, in which the vertical axis (7) of the lifting station intersects both the longitudinal axis (5) and the pivoting circumference (4). This device is useful in making sand molds for foundry molding machines. This device makes it possible to change the model plates without interrupting the rate downstream of the molding machines. In addition, it allows parts of the model plates to be positioned outside the molding machine.
