Description

Druckstempel 6zum Gießen von flüssigem Metall unter Explosionsdruck für zahnärztliche Zwecke Die Erfindung betrifft einen Druckstempel zum Gießen von flüssigem Metall unter Explosionsdruck für zahnärztliche Zwecke und besteht darin, daß der Explosionsstoff innerhalb eines Hohlraumes gelagert ist, der von einer Aufsatzhaube für die Gießform am Druckstempelendc und einem mit Durchlaß kanälen für die Explosionsgase versehenen Verschluß der Haube gebildet wird. Hierdurch svird den bekannten Gußapparaten gegenüber der Vorteil erzielt, das geschmolzene Metall mit größerem und ruckartig auftretendem Druck in die Form zu presself, so daß schwerfließende und hocbschmel zende Legierungen in der Gußform ausfließen können. Die meisten Apparate arbeiten mit Druckluft oder Dampf. Auch Schleuderappa rate werden zum Gießen verwendet. Allen diesen Apparaten haftet der Fehler an, daß sie nicht genügend schnell und mit genügend großem Druck das Material vergießen bzw. in die Gußform pressen.Pressure ram 6 for pouring liquid metal under explosion pressure for dental purposes The invention relates to a ram for casting liquid metal under explosion pressure for dental purposes and consists of that the explosive is stored within a cavity by a hood for the mold at the Druckstempelendc and one with passage channels for the explosion gases provided closure of the hood is formed. This saves the well-known casting machines versus the advantage achieved, the molten metal with larger and jerky occurring pressure in the form to presself, so that hard-flowing and hocbschmel Zende alloys can flow out in the mold. Most of the machines work with compressed air or steam. Centrifugal machines are also used for casting. All The fault of these apparatuses is that they are not fast enough and with sufficient speed Pour the material under high pressure or press it into the mold.

Die den Hohlraum für den explosiven Stoff enthaltende Aufsatzhaube wird vor jedem Guß mit dem Ende des Druckstempels verwunden, mit Explosivstoff in beliebiger Menge gefüllt und durch Einschrauben der Verschlußplatte geschlossen. The hood containing the cavity for the explosive substance is wound with the end of the pressure ram before each casting, with explosive in Any amount filled and closed by screwing in the closure plate.

Beim Aufsetzen des Druckstempels mit der mit Explosionsstoff gefüllten Aufsatzhaube auf die Gußform wird der Explosionsstoff durch das geschmolzene Metall zur Explosion gebracht, und die Explosionsgase strömen durch die Durchlaßkanäle der Verschlußkappe und pressen das geschmolzene Metall unter großem Druck ruckartig in die Form. When placing the pressure stamp with the one filled with explosive Attachment hood to the mold, the explosive is through the molten metal caused to explode, and the explosion gases flow through the passage channels the cap and jerk the molten metal under great pressure in the form.

Je größer die Anzahl der Durcblaßkanäle und je feiner dieselben sind, um so gleichmäßiger ist der Druck.The greater the number of outlet channels and the finer they are, the more even is the pressure.

Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt. und zwar zeigt Fig. 1 einen Längsschnitt einer Gußvorrichtung mit einem Druckstempel nach der Erfindung, Fig. 2 die Verschlußplatte der Aufsatzhaube und Fig. 3 die Platte nach Fig. 2 von unten gesehen. a ist eine am Ende des Druckstempels an bringbare Aufsatzhaube für die Gießform, die durch eine Verschlußplatte b mit Schraubengewinde c abgeschlossen werden kann. Die Platte c trägt eine Vielzahl von feinen Durchlaßkanälen d. In der Aufsatzhaube a wird durch Einschrauben der Verschlußp]atte b ein Hohlraum e zur Aufnahme des Explosionsstoffes gebildet. The subject of the invention is shown in the drawing, for example. namely, Fig. 1 shows a longitudinal section of a casting device with a plunger according to the invention, Fig. 2 the closure plate of the hood and Fig. 3 the plate seen from below according to Fig. 2. a is an attachable at the end of the plunger Attachment hood for the casting mold, which is through a closure plate b with screw thread c can be completed. The plate c carries a multiplicity of fine passage channels d. A cavity is created in the hood a by screwing in the closure plate b e formed to absorb the explosive.
