 EMI2.1 
 Wasserleitung durch eine Schlauchverbindung 13 in der aus der Zeichnung ersichtlichen Weise an die Wanne 1 anzuschliessen ist. 



   Unter der Presswanne ist eine Heizvorrichtung 15 vorgesehen, durch welche die bei manchen Formereiverfahren bzw. manchen Formmassen erwünschteAnwärmung der Formmassetafel vor oder während des Pressvorganges bewirkt werden kann. 



   Die Vorrichtung zur Durchführung des Verfahrens kann im Rahmen des dargelegten 
 EMI2.2 
 unmittelbar vor der Pressung auf hydraulischem Wege gegen das Modell gepresst wird. 



    PATENT-ANSPRÜCHE:  
1. Verfahren zur Herstellung von Modellabdrücken für Formereizwecke aller Art, dadurch   gekennzeichnet,   dass das abzuformende Modell mit der Formmasse auf eine durch hydrostatischen Flüssigkeitsdruck gespannte Membrane aus elastischem Baustoff (z. B.   Gummi)   aufgelegt und hierauf zwischen dieser Membrane und einer festen Widerlage hydraulisch abgeformt wird.

 EMI2.1
 The water line is to be connected to the tub 1 through a hose connection 13 in the manner shown in the drawing.



   A heating device 15 is provided under the press tub, by means of which the heating of the molding compound sheet, which is desired in some molding processes or in some molding compounds, can be brought about before or during the pressing process.



   The device for performing the method can be used within the scope of the above
 EMI2.2
 is pressed against the model by hydraulic means immediately before pressing.



    PATENT CLAIMS:
1. A method for producing model impressions for all kinds of molding purposes, characterized in that the model to be molded with the molding compound is placed on a membrane made of elastic building material (e.g. rubber) tensioned by hydrostatic fluid pressure and then hydraulically between this membrane and a fixed abutment is molded.

Claims (1)

2. Presse zur Durchführung des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, dass sie aus einer mit einer Membrane (x) überspannten Wanne (1) und einem Druckgefäss (8) besteht, das unter Zwischenschaltung eines Druckmultiplikators (z. B. einer Pumpe) mit der Wanne in Verbindung steht. 2. Press for carrying out the method according to claim 1, characterized in that it consists of a tub (1) spanned by a membrane (x) and a pressure vessel (8) which, with the interposition of a pressure multiplier (e.g. a pump) communicates with the tub. 3. Presse nach Anspruch 2, dadurch gekennzeichnet, dass in die das Druckgef ss (8) mit der Wanne (1) verbindende Leitung ein Sperrorgan (9) eingebaut ist, das in seiner Offenstellung eine direkte Verbindung zwischen Wanne und Druckgefäss ermöglicht und in seiner Schliessstellung die Entnahme bzw. Überführung von Arbeitsfüssigkeit aus dem Druckgefäss in die Wanne gewährleistet. 3. Press according to claim 2, characterized in that in the pressure vessel (8) with the tub (1) connecting line, a locking member (9) is installed, which in its open position enables a direct connection between the tub and pressure vessel and in its In the closed position, the removal or transfer of working fluid from the pressure vessel into the tub is guaranteed. 4. Presse nach Anspruch 2. dadurch gekennzeichnet, dass die ruhende, feste Widerlage der Presse von mehreren Öffnungen (6) durchbrochen und zwischen der Widerlage und dem abzuformenden Modell ein Belag (11) aus luftdurchläsigem Baustoff angeordnet ist. EMI2.3 4. Press according to claim 2, characterized in that the stationary, fixed abutment of the press is broken by several openings (6) and a covering (11) made of air-permeable building material is arranged between the abutment and the model to be molded.
