Description

Die Erfindung betrifft eine Kern- und Maskenschiessmaschine mit einem Maschinenständer, einem Werkzeugträger, einer Schiessvorrichtung und einer Entnahmevorrichtung.The invention relates to a core and mask shooting machine with a machine stand, a tool holder, a shooting device and a removal device.

Bei bekannten Maschinen der vorgenannten Art, die als Einzel-oder Mehrstationen-Anlagen in der Giesserei- und Kunststofftechnik Anwendung finden und zur Herstellung von Kernen und Masken bzw. Giess- und Formstücken dienen, ist es bei einem Wechsel der Werkzeuge und der damit verbundenen Schiessvorrichtung erforderlich, die Maschine bzw. die Anlage für längere Zeit stillzusetzen. Die Werkzeuge müssen dann mühsam mittels Hebezug aus dem Werkzeugträger entfernt werden, bevor ein neues Werkzeug auf die gleiche Art und Weise in den Werkzeugträger eingebaut werden kann. Auch der Wechsel der Schiessvorrichtung gestaltet sich innerhalb der Maschine sehr zeitraubend und aufwendig. Ein schneller und rationeller Werkzeugwechsel und die damit verbundene Umrüstung der Schiessvorrichtung ist auf diese Weise nicht durchführbar.In the case of known machines of the aforementioned type, which are used as single or multi-station systems in foundry and plastics technology and are used for the production of cores and masks or castings and moldings, the tools and the associated shooting device are changed necessary to shut down the machine or system for a long time. The tools must then be laboriously removed from the tool carrier using a hoist before a new tool can be installed in the tool carrier in the same way. Changing the shooting device is also very time-consuming and complex within the machine. A quick and efficient tool change and the associated retrofitting of the shooting device cannot be carried out in this way.

Aus der DE-C-3148461 ist eine Kern- und Maskenschiessmaschine mit einem Maschinenständer, einem Werkzeugträger, einer Schiessvorrichtung und einer Entnahmevorrichtung bekannt, bei der der Werkzeugträger mit einer doppelten, um eine horizontale Achse drehbaren Werkzeugaufnahme und einer damit zusammenwirkenden, aus zwei miteinander verbundenen Schusskessein bestehenden und um eine vertikale Achse schwenkbaren Schiessvorrichtung ausgestattet ist.From DE-C-3148461 a core and mask shooting machine with a machine stand, a tool holder, a shooting device and a removal device is known, in which the tool holder with a double tool holder which can be rotated about a horizontal axis and which interacts with it and consists of two connected to one another Shot box is provided in the existing shooting device which can be pivoted about a vertical axis.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, bei einer gattungsmässigen Vorrichtung der vorgenannten Art den Wechsel des horizontal geteilten Werkzeugs mit der Düsen-und Ausstosserplatte automatisch und gleichzeitig vorzunehmen, ohne dass die Maschine dazu stillgelegt zu werden braucht.The object of the present invention is to change the horizontally divided tool with the nozzle and ejector plate automatically and simultaneously in a generic device of the aforementioned type, without the machine needing to be shut down.

Die Lösung dieser Aufgabe wird durch die technische Lehre vermittelt, dass der Werkzeugträger mit einem um eine vertikale Achse schwenkbaren doppelten Werkzeugwechselrahmen ausgerüstet ist, dem eine Ausstosserplatte, eine Schussplatte und eine Düsenplatte zugeordnet sind, und mit dem Wechselrahmen gleichzeitig das alte Werkzeug mit der Ausstosserplatte ausschwenkbar und das neue Werkzeug zusammen mit der neuen Schussplatte bzw. Ausstosserplatte auswechselbar sind, wobei die Demontage der alten Düsenplatte gleichzeitig mit dem Einwechsel n des Werkzeugs ausserhalb des Werkzeugträgers mit einer separaten, drehbar um eine vertikale Achse angeordneten Düsenplattenwechselvorrichtung vorgenommen wird.The solution to this problem is conveyed by the technical teaching that the tool carrier is equipped with a double tool change frame that can be pivoted about a vertical axis, to which an ejector plate, a firing plate and a nozzle plate are assigned, and that the old tool with the ejector plate can be swung out at the same time and the new tool can be exchanged together with the new firing plate or ejector plate, the dismantling of the old nozzle plate being carried out simultaneously with the replacement of the tool outside the tool carrier with a separate nozzle plate changing device arranged rotatably about a vertical axis.

Gemäss Erfindung kann der Werkzeugwechsel in wenigen Minuten durchgeführt werden. Hierzu wird mit einer hydraulisch horizontal um eine vertikale Achse schwenkbaren doppelten Werkzeugwechselvorrichtung oder einem Tragarm das alte Werkzeug nach dem Lösen der hydraulischen Schnellspanner zwischen dem hydraulischen Hubtisch und dem Werkzeugunterteil bzw. nach dem Abfahren des Hubtisches, auf dem Tragarm liegend, aus der Maschine herausgeschwenkt und gleichzeitig das neue Werkzeug über den Hubtisch eingeschwenkt.According to the invention, the tool change can be carried out in a few minutes. For this purpose, the old tool is swung out of the machine with a hydraulically horizontally swiveling vertical tool axis or a support arm after loosening the hydraulic quick release between the hydraulic lifting table and the lower tool part or after moving the lifting table, lying on the support arm, and at the same time the new tool swung in over the lifting table.

Mit dem Auffahren des hydraulischen Hubtisches wird das Werkzeugoberteil gegen die obere Werkzeugzentrierung im Maschinenständer angehoben. Mit einer pneumatisch/mechanischen Verriegelung wird das Werkzeugoberteil fest an den Maschinenständer angebunden. Beim Auswechseln des Werkzeuges erfolgt dieser Ablauf in umgekehrter Reihenfolge.When the hydraulic lifting table is opened, the upper part of the tool is raised against the upper tool centering in the machine stand. The upper part of the tool is firmly connected to the machine stand with a pneumatic / mechanical lock. When replacing the tool, this process takes place in the reverse order.

Parallel mit dem Werkzeug wird auch die obere Ausstosserplatte ausgetauscht. Hierzu ist die obere Ausstossvorrichtung, bei heissen Maschinen kombiniert mit der Heizstation, bei kalten Maschinen kombiniert mit der oberen Begasungsstation, mit einer automatischen Ausstosserplatten-Verklammerung zum Befestigen der Ausstosserplatte an der Vorrichtung ausgerüstet.The upper ejector plate is also replaced in parallel with the tool. For this purpose, the upper ejection device, combined with the heating station on hot machines, combined with the upper gassing station on cold machines, is equipped with an automatic ejector plate clamp for fastening the ejector plate to the device.

Ebenso wird die Düsenplatte mit einer automatischen Düsenplatten-Verklammerung an der Schusshaube befestigt. Das Entfernen der Düsenplatte erfolgt nach dem Auffahren der Düsenplatten-Schnellwechselvorrichung und nach dem Lösen der Düsenplatten-Verklammerung ausserhalb des Werkzeugträgers gleichzeitig mit dem WerkzeugwechselThe nozzle plate is also attached to the shooting hood with an automatic nozzle plate clamp. The nozzle plate is removed after opening the nozzle plate quick-change device and after loosening the nozzle plate clamp outside the tool holder at the same time as the tool change

Der noch im Sandmagazin bzw. in der Schusshaube befindliche Restsand fällt in eine Auffangwanne, die um die Düsenplatten-Schnellwechselvorrichtung aufgebaut ist. Somit wird eine Verschmutzung des Werkzeugträgers in der Maschine vermieden und die Grundvoraussetzung geschaffen, dass ein störungsfreier Werkzeugwechsel durchgeführt werden kann.The remaining sand that is still in the sand magazine or in the firing hood falls into a collecting trough that is built up around the nozzle plate quick-change device. Soiling of the tool carrier in the machine is avoided and the basic requirement is created that a trouble-free tool change can be carried out.

Die neue Düsenplatte wird mit dem neuen Werkzeug oberhalb der auch aufliegenden Ausstosserplatte in die Maschine eingeschwenkt und dort an der Schusshaube automatisch befestigt.The new nozzle plate is swiveled into the machine with the new tool above the ejector plate, which is also on top, and automatically attached to the shooting hood.

Danach wird die Schiessstation unter den Sandbunker, d.h. in Nachfüllstellung, verfahren. Somit befindet sich dann die obere Ausstosservorrichtung über der noch auf dem Werkzeug liegenden Ausstosserplatte. Mit der automatischen Verkfammerung wird diese Platte mit der Ausstosserplatte mechanisch verbunden. Der Steuerungsablauf kann wahlweise in Einzelschaltung oder vollautomatisch vorgesehen werden.Then the shooting station is under the sand bunker, i.e. in refill position, move. The upper ejector device is then located above the ejector plate still lying on the tool. With automatic stapling, this plate is mechanically connected to the ejector plate. The control sequence can be provided either individually or fully automatically.
