Description

Mit einem nachgiebigen Uberzug aus Gummi od. dgl. versehene Metallform zum Pressen keramischer Massen Die Erfindung betrifft eine Preßform mit aufgelegten Gummiplatten, wie sie für die Auspressung von keramischen Massen Verwendung finden, wobei die lie#,ondere Ausbildung der Gummihaut und der Metallforrnen und die Verbindungsart zwischen Gummihaut und Metallformen auch die Verwendung bei Formen mit großen und unregelmäßigen Vertiefungen ermöglicht.Metal mold provided with a flexible covering made of rubber or the like for pressing ceramic masses The invention relates to a press mold with an overlay Rubber plates, such as those used for pressing out ceramic masses, the other design of the rubber skin and the metal molds and the type of connection between rubber skin and metal molds, it can also be used for molds with large and allows irregular depressions.

Es sind schon Formen zum Pressen von keramischen Gegenständen bekannt, welche mit dünnen Gummiüberzügen oder locker aufgelegten Gummiplatten versehen sind. Diese Maßnahmen, die bei Metallformen zur Ersparung der Gipsform getroffen wurden., haben sich. jedoch nicht in allen Fällen bewährt. Insbesondere ist es nacht gelungen, sie bei der Ausformung von Gegenständen mit großen Vertiefungen oder Nuten zur Anwendung zu bringen.Molds for pressing ceramic objects are already known, which are provided with thin rubber covers or loosely applied rubber plates. These measures, which were taken with metal molds to save the plaster mold., have. however not proven in all cases. In particular, it succeeded at night they are used in the molding of objects with large depressions or grooves bring to.

Man hat weiterhin versucht, in den Formen Luftlöcher vorzusehen, durch welche die Luft beim Pressen entweichen kann. Hierbei mußten die Gummiüberzüge an den Stellen der Luftlöcher mit Durchbrüchen versehen sein, um die Luft herauszulassen. Es hat sich jedoch gezeigt, daß die keramische Masse sich dabei unter die Gummiplatte setzt und dadurch das gewünschte Profil verändert. Auch ein Festkleben der Gummiüberzüge an den Formen konnte diese Ghelstände nicht beseitigen.Attempts have also been made to provide air holes in the molds which the air can escape during pressing. Here the rubber covers had to be on the places of the air holes be provided with openings to let the air out. However, it has been shown that the ceramic mass is thereby under the rubber plate sets and thereby changes the desired profile. Also sticking of the rubber covers in the forms could not remove this problem.

Die Erfindung überwindet diese Schwierigkeiten dadurch, daß sie dünne Folien aus einem biegsamen, nachgiebigen Stoff, wie z. B. Gummi, verwendet, die mit schlauchförmigen Ansätzen versehen sind, «-elche durch die Luftlöcher der Form hindurchgeführt werden. In der Zeichnung sind beispielsweise Ausführungsformen der Erfindung dargestellt.The invention overcomes these difficulties by making them thin Sheets made of a flexible, resilient material, such as. B. rubber, used the are provided with tubular attachments, «-elche through the air holes of the mold be passed through. In the drawing, for example, embodiments of the Invention shown.

Fig. 1 zeigt in senkrechtem. Schnitt eine Metallform 1 für keramische Massen an der Stelle, wo sich ein durchgehendes Luftloch 2 befindet. Die dünne Gummifolie 3, welche sich allen Teilen der Form an schmiegt, weist einen schlauchartigen Ansatz 4 auf, dessen Rand 5 sich an die Unterseite der Form anlegt.Fig. 1 shows in the vertical. Cut a metal mold 1 for ceramic Masses at the point where there is a continuous air hole 2. The thin rubber sheet 3, which hugs all parts of the mold, has a tube-like approach 4, the edge 5 of which rests against the underside of the mold.

In Fig. 2 ist eine andere 1Teta@llform 6 dargestellt, welche eine Ausnehmung 7 aufweist. In den Boden dieser Ausnehmung mündet das Luftloch 8, und durch dieses führt der Schlauchansatz 9, der mit der Folie 3 au: einem Stück bestehen kann. Beim Pressen wird die Luft durch den Schlauchansatz 9 nach außen geführt, ohne daß sich Material zwischen Gummifolie und Form drängen kann, wie dies der Fall wäre, wenn die Folie 3 lediglich mit einer Öffnung 10 über dem Luftloch 8 versehen wäre, wie in Fig. 3 gezeigt ist. Der Ton kriecht hier unter den Rand der Folie. liebt diesen an und bildet einen Knoten 11.In Fig. 2, another 1Teta @ llform 6 is shown, which a Has recess 7. The air hole 8, and opens into the bottom of this recess the hose extension 9, which is made in one piece with the film 3, leads through this can. When pressing, the air is led to the outside through the hose attachment 9, without material being able to squeeze between the rubber sheet and the mold, as is the case if the film 3 were only provided with an opening 10 above the air hole 8 would be as shown in FIG. The clay creeps under the edge of the foil here. loves this and forms a knot 11.

Bei der Ausführungsform nach Fig.4 weist der Schlauchansatz 8 am Ende eine Wulst 12 auf, die sowohl zur Verstärkung als auch zur Verbesserung des Haftens dient.In the embodiment according to FIG. 4, the hose attachment 8 has at the end a bead 12, which both to reinforce and to improve the adhesion serves.

Bei der Ausführungsform der Fig. 2 haben die verschiedenen schlauchförmigen Ansätze, von denen nur einer bei 9 dargestellt ist, noch andere, weitere Funktionen übernommen; sie ziehen nämlich d!ie Folie, in die Ausnehmung 7 der Form hinein und sorgen für eine gute Anlage der Folie in der Form.In the embodiment of FIG. 2, the various tubular Approaches, only one of which is shown at 9, have other, additional functions accepted; namely, they pull the film into the recess 7 of the mold and ensure that the film rests well in the mold.
