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.
