Abstract
Description
Die Erfindung betrifft ein Gerät, das die Arbeitsvorgänge des Schmelzens der thermoplastischen Kunststoffe und das Injizieren der geschmolzenen Masse unter Vacuum gemäß dem Oberbegriff des Anspruches 1 unter Verwendung eines vacuumverdichteten Gehäuses gemäß den nebengeordneten Ansprüchen 2, 3, 4, 5 und 6 ermöglicht.The invention relates to a device that performs the operations of melting of the thermoplastics and injecting the melted Mass under vacuum according to the preamble of claim 1 under Use of a vacuum-sealed housing according to the secondary claims 2, 3, 4, 5 and 6 allows.
Für die bisher bekannten Systeme in der Zahntechnik werden Geräte verwendet, die ohne Vacuum und mit hohem Druck (bis zu 10-12 Bar) arbeiten. Somit sind die Abformungen der Zahnprothesen, die nur mit Gips gestaltet werden können, immer bruchgefährdet.Devices are used for the previously known systems in dental technology used without vacuum and with high pressure (up to 10-12 bar) work. Thus, the impressions of the dentures are only with Plaster can be designed, always at risk of breakage.
Die Erfindung zeigt, wie mit der Anwendung des Vacuums die Masse in der Heizkammer nicht nur homogen geschmolzen, sondern gleichzeitig während des Aufwärmens von der Feuchtigkeit befreit wird, was eine sehr wichtige Voraussetzung für die Erhaltung der technischen und klinischen Eigenschaften thermoplastischer Kunststoffe ist.The invention shows how, with the application of the vacuum, the mass in the heating chamber not only melted homogeneously, but simultaneously the moisture is removed during the warm-up, which is a very important prerequisite for the maintenance of technical and clinical Properties of thermoplastics.
Die Masse wird ohne Luftwiderstand in die Muffel, die die Abformung aus Gips umschließt, injiziert.The mass is placed in the muffle without air resistance, which is the impression Plaster encloses, injected.
Das Gerät besteht aus einem vacuumdrucksicheren, dem Romboid ähnlichen Gehäuse Fig. 1 Draufsicht, das im Inneren mit allen im Raum vorhandenen Bestandteilen und Materialien unter Vacuum gestellt wird.The device consists of a vacuum pressure-proof housing similar to the romboid . Fig. 1 Top view, which is placed inside with all components and materials in the room under vacuum.
Der Boden für die Küvette Fig. 2 ist mit dem oberen Teil des Gehäuses fest verbunden. Die Küvette Fig. 3 wird mit dem Druck einer Schraube Fig. 4 von oben und außerhalb des vacuumdrucksicheren Gehäuses am Boden festgehalten. The bottom for the cuvette Fig. 2 is firmly connected to the upper part of the housing. The cuvette Fig. 3 is held on the floor with the pressure of a screw Fig. 4 from above and outside the vacuum pressure-proof housing.
Der Anschluß Fig. 5 der Heizkammer Fig. 6 befindet sich am Boden der tragenden Plattform direkt unter der Küvette. Der Kolben Fig. 7a der Heizkammer ist stabil verbunden Fig. 7b mit den zwei Kolben Fig. 8 der Pumpen Fig. 9, die neben der Küvette aus platzsparenden Gründen angebracht sind. Diese nehmen beim Injizieren der flüssigen Masse den Kolben der Heizkammer mit nach oben.The connection Fig. 5 of the heating chamber Fig. 6 is located on the bottom of the supporting platform directly under the cuvette. The piston Fig. 7a of the heating chamber is stably connected. Fig. 7b with the two pistons Fig. 8 of the pumps Fig. 9, which are attached next to the cuvette for space-saving reasons. When the liquid mass is injected, these take the piston of the heating chamber upwards.
Der thermolastische Kunststoff wird in die senkrechte Heizkammer durch die Öffnung Fig. 10 an der tragenden Plattform für die Küvette ohne Kartusche eingeschoben, um den Druck für das Injizieren zusätzlich zu reduzieren.The thermoplastic plastic is inserted into the vertical heating chamber through the opening Fig. 10 on the supporting platform for the cuvette without a cartridge, in order to further reduce the pressure for injecting.
Für den Fall, daß die thermoplastischen Kunststoffe besonders schnell nach dem Injizieren abgekühlt werden müssen, ist innerhalb des vacuumdrucksicheren Gehäuses eine Vorrichtung Fig. 11 angebracht, an welche die Küvette für die Wasserabkühlung angeschlossen werden kann.In the event that the thermoplastics have to be cooled particularly quickly after injection, a device Fig. 11 is attached within the vacuum pressure-proof housing to which the cuvette for water cooling can be connected.
