Description
Apparat zur Herstellung von Ersatzstücken für zahnärztliche Zwecke. Die Erfindung betrifft einen Apparat zur Herstellung von Press.guss-Ersatzstücken für zahnärztliche Zwecke und besteht darin. dass eine Vorrichtung angeordnet ist, ver möge deren ein zur Aufnahme mehrerer Zy linder oder dergleichen verschiedener Höhe geeigneter Druckbehälter und seine zu gehörige Deckelhaube sich von.- bezw. gegen einander bewegen und aufeinanderpressen lassen,
so dass in den Behälter eingeführte Pressluft auf die Formzylinder zwecks gleich zeitiger Herstellung mehrerer Ersatzstücke in einem Arbeitsgange einwirken kann.
Auf der Zeichnung ist der Erfindungs gegenstand in einer beispielsweisen Ausfüh rungsform veranschaulicht, und zwar zeigt: Abb. 1 eine Vorderansicht des Apparates, mit Querschnitt von Deckelhaube und Druck behälter, Abb. 2 eine Seitenansicht hierzu.
Der gezeichnete Apparat besitzt zwei Zahnstangen a und<I>b,</I> in welche zwei Zahn räder c und d eingreifen, die mittelst des Handrades e angetrieben und so, die Zahn stangen auf- und abbewegt werden können. Der obere Verbindungssteg f der Stangen trägt die Deckelhaube. Wird das 'Handrad e entsprechend gedreht, so werden die Zahn stangen a und b nach unten gezogen und somit die Deckelhaube auf den Druckbehäl ter g gepresst, in welchem sich die Form zylinder<I>k</I> und<I>l</I> befinden.
Sind Deckelhaube und Druckbehälter fest aufeinander gepresst und wird dann Pressluft durch die hohle Stange b in den glockenförmigen Deckelraum la eingeführt, so verteilt sich diese Luft gleichmässig in folge der verschiedenen angebrachten Löcher i. in den Hohlraum von Deckelhaube und Druckbehälter, also auch auf die darin be findlichen Formzylinder k und l' mit dem geschmolzenen Metall. Letzteres wird da durch bis in die feinsten Ausläufer der Form hinein gepresst und ergibt somit dichte und bis in die feinsten Enden ausgeprägte Er satzstücke.
Apparatus for making replacements for dental purposes. The invention relates to an apparatus for the production of Press.guss replacement parts for dental purposes and consists in it. that a device is arranged, ver may one for receiving several cylinders or the like of different heights suitable pressure vessel and its associated cover hood from.- respectively. move against each other and let them press against each other,
so that compressed air introduced into the container can act on the forme cylinder for the purpose of the simultaneous production of several replacement parts in one operation.
In the drawing, the subject of the invention is illustrated in an exemplary embodiment, namely: Fig. 1 is a front view of the apparatus, with a cross section of the lid and pressure vessel, Fig. 2 is a side view of this.
The drawn apparatus has two toothed racks a and <I> b, </I> in which two toothed wheels c and d engage, which are driven by means of the handwheel e and so the toothed racks can be moved up and down. The upper connecting web f of the rods carries the cover hood. If the handwheel e is rotated accordingly, the toothed rods a and b are pulled down and the cover hood is thus pressed onto the pressure vessel g, in which the cylinder <I> k </I> and <I> l < / I> are located.
If the cover hood and pressure vessel are firmly pressed together and compressed air is then introduced through the hollow rod b into the bell-shaped cover space la, this air is evenly distributed as a result of the various holes i made. into the cavity of the cover hood and pressure vessel, i.e. also onto the forme cylinders k and l 'with the molten metal contained therein. The latter is pressed right into the finest extensions of the mold and thus results in dense replacement pieces that are pronounced right down to the finest ends.
