Description
Konische Hülse für eine Arbeitsform aus Gips zur Herstellung von keramischen Hohlwaren Die Erfindung betrifft eine konische Hülse aus formstabilem Werkstoff für eine Arbeitsform aus Gips zur Herstellung von keramischen Hohlwaren, wie sie beispielsweise aus der USA.-Patentschrift 1937184 bekanntgeworden ist.Conical sleeve for a working form made of plaster for the production of ceramic Hollow goods The invention relates to a conical sleeve made of dimensionally stable material for a work mold made of plaster of paris for the production of ceramic hollow ware, such as her for example from the USA patent 1937184 has become known.
Der Erfindung liegt die Aufgabe zugrunde, eine derartige Hülse so auszubilden, daß die Gipsmasse nach ihrem Aushärten einerseits in der Hülse auf einfache Art sicher verankert ist und andererseits nach Abnutzung leicht von der Hülse gelöst werden kann.The invention is based on the object of such a sleeve to train that the plaster of paris after its hardening on the one hand in the sleeve simple type is securely anchored and on the other hand easily from the wear and tear Sleeve can be solved.
Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß der Rand der kleineren Öffnung der Hülse eine sich nach außen erweiternde Abschrägung aufweist.According to the invention, this object is achieved in that the edge the smaller opening of the sleeve has an outwardly widening bevel.
Eine solche Ausführungsform ist weder nach ihrer Ausbildung noch nach ihrer Wirkungsweise mit jener vergleichbar, die aus der deutschen Patentschrift 568 289 bekanntgeworden ist. Das der Hülse gleichzusetzende, dort als Sockel bzw. Verstärkungsstück bezeichnete Teil ist mit der Arbeitsform durch ein Schraubgewinde verbunden, das gegebenenfalls durch ineinandergreifende Vorsprünge und Vertiefungen ersetzbar sein soll, um ein Drehen des Gipsteiles auf dem Sockel zu verhindern.Such an embodiment is neither after its training nor after their mode of action is comparable to that from the German patent specification 568 289 has become known. That which is to be equated with the sleeve, there as a base or Part called reinforcement piece is threaded with the working shape through a screw thread connected, optionally by interlocking projections and depressions should be replaceable to prevent turning of the plaster part on the base.
Die neue Querschnittsform an der kleineren Hülsenöffnung bildet im Prinzip eine Schwalbenschwanzverankerung. Eine solche ist zwar an sich im allgemeinen bekannt. Auf dem engen Gebiet der Hülsen für Arbeitsformen und in der vorliegenden Art ist sie jedoch noch nie benutzt worden, obgleich ein entsprechender Bedarf seit längerer Zeit bestanden hat.The new cross-sectional shape at the smaller sleeve opening forms the Principle of a dovetail anchorage. Such is in itself in general known. In the narrow field of sleeves for working forms and in the present Art, however, it has never been used, although there has been a need since has existed for a long time.
Eine zweckmäßige Ausführungsform der Erfindung besteht darin, daß der Rand der Hülse eingezogen ist. An Hand der Zeichnung ist die Erfindung beispielsweise erläutert, und zwar in der Herstellungsphase der Arbeitsform.An advantageous embodiment of the invention is that the edge of the sleeve is pulled in. With reference to the drawing, the invention is an example explained, in the manufacturing phase of the working form.
Ein Drehteller 1 mit einem Bund 3 trägt einen Kern 2. Auf den Bund 3 ist ein Zentrierring 4 mit einer entsprechenden Ausstufung 5 aufgesetzt, der mit einer zweiten Ausstufung 6 einen entsprechenden Stufenrand 7 einer konischen Hülse 8 hält, deren kleinere Öffnung oben liegt. Diese weist einen nach innen eingezogenen Rand 9 auf, der mit einer sich nach außen erweiternden Abschrägung 10 versehen ist.A turntable 1 with a collar 3 carries a core 2. A centering ring 4 with a corresponding step 5 is placed on the collar 3, which with a second step 6 holds a corresponding step edge 7 of a conical sleeve 8, the smaller opening of which is at the top. This has an inwardly drawn-in edge 9 which is provided with an outwardly widening bevel 10 .
Wird zur Herstellung der Arbeitsform in die Hülse 8 Gipsmasse eingefüllt und über den Rand 9 abgestrichen, so bildet sich durch die Abschrägung 10 eine Art Schwalbenschwanzverankerung, die die Gipsform sicher in der Hülse hält, wenn diese vom Drehteller 1 abgenommen ist. Nach Abnutzung der Arbeitsform läßt sich der die Verankerung bildende Gips leicht herausschneiden und dadurch die Gipsform mühelos aus der Hülse 8 herausnehmen.If plaster of paris is poured into the sleeve 8 and wiped over the edge 9 to produce the working form, a kind of dovetail anchorage is formed by the bevel 10 , which holds the plaster form securely in the sleeve when it is removed from the turntable 1. After the working form has worn off, the plaster of paris forming the anchorage can easily be cut out and the plaster of paris form can thus be easily removed from the sleeve 8 .
