Abstract

Die Erfindung betrifft eine Zweistationen-Hochleistungsformmaschine zur Herstellung kastengebundener Sandformen unter Verwendung von mindestens einem Modellplattenpaar. In einer ersten Station A werden Modell und Formkasten zu einer Formeinheit 4.05 zusammengefügt und von einer verfahrbaren Formsandeinfüllvorrichtung 2.14 schichtweise mit Formsand gefüllt. In einer zweiten Station B wird die Form verdichtet und das Modell von der Form getrennt. Die mit Formsand gefüllte Formeinheit 4.05 wird zusammen mit dem Formkastentransport 1.08 auf den Rollenbahnen 2.03/3.03 von der Station A zur Station B transportiert, während gleichzeitig eine Modellplatte 4.04 auf der Rollenbahn 1.05 von der Station B zur Station A zurück transportiert wird. Für den Formkasten 4.01 sind dabei nur sehr geringfügige vertikale Bewegungen 2.06 erforderlich.
Die Füllrahmenfunktion übernimmt ein Modellfüllrahmen 4.03 und ein Verdichtungsfüllrahmen 3.22. Die Modelleinheit 4.02 weist einen teleskopartig angeordneten und vertikal verschiebaren Modellfüllrahmen 4.03 auf, der im angehobenen Zustand 2.07 zusammen mit dem Formkasten 4.01 die Formeinheit 4.05 mit dem Füllraum 2.39 für den losen Formstoff bildet. Die Verdichtungsvorrichtung 3.14/3.15 in der Arbeitsstation B weist einen teleskopartig angeordneten und vertikal verschiebbaren Verdichtungsfüllrahmen 3.22 auf, der zum Verdichten auf den Formkasten 4.01 auflegbar und für den Formkastentransport 1.08 vom Formkasten abhebbar ist. In der Station B schiebt der Hubtisch 3.01 die Modelleinheit 4.02 innerhalb des Modellfüllrahmens 4.03 nach oben, wobei der verdrängte Formsand in den auf den Formkasten 4.01 abgesetzten Verdichtungsfüllrahmen 3.22 geschoben wird, wonach die Verdichtung erfolgt. Die beim Hochschieben des Formsandes verdrängte Luft wird zum Fluidisieren verwendet.
