Description
Beschreibung zum Formenfüll gerät mit AuswerferDescription of the mold filling device with ejector
Dieses Gerät dient zur Weiterverarbeitung von aufschäumbarem Polystyrol und
zwar wird das bereits vorgeschäumte Material mit Hilfe dieses Gerätes in Formen eingeblasen und nach der Versinterung bzw. Verschweißung dieser einzelnen
Partikel drückt das Formenfüll gerät mit Auswerfer Teile aus den Formen
heraus.
Folgende Arbeitsabläufe finden dabei statt:This device is used for the further processing of foamable polystyrene and that the pre-expanded material is blown into molds with the help of this device and after the sintering or welding of these individual particles, the mold filling device with ejector pushes parts out of the molds.
The following workflows take place:
1. Füllen; Der Kolben, Pos. 21, wird in die eingezeichnete Lage yon einem Pneumatikzylinder gebracht. Über einen Schlauchanschluß, Pos. 24, wird die Düse, Pos. 27, mit Druckluft beaufschlagt. Durch die eingezeichneten Bohrungen D strömt die Druckluft in das Füllrohr, Pos. 30. Dadurch entsteht in dem Raum E sowie im Zufuhrstutzen, Pos. 23, Unterdruck. Durch diesen Unterdruck werden die aufbereiteten Polystyrolperlen angesaugt und in den Formraum geblasen. 1. fill; The piston, item 21, is brought into the position shown by a pneumatic cylinder. Compressed air is applied to the nozzle, item 27, via a hose connection, item 24. The compressed air flows through the drawn-in bores D into the filling pipe, item 30. This creates negative pressure in space E and in the feed connector, item 23. Due to this negative pressure, the processed polystyrene beads are sucked in and blown into the mold space.
2. Schliessen: 1st die Form gefüllt, wird die Düse, Pos. 27, durch Druckluft entlastet. Der Kolben, Pos. 21, wird in die untere Endlage des Füllrohres, Pos. 30, mit Hilfe des pneumatischen Zylinders geschoben. Durch die eingezeichnete;. Dichtung am Kolben, Pos. 21, wird der Raum E vollkommen dicht vom Formraum abgeschlossen. 2. Closing: If the mold is filled, the nozzle, item 27, is relieved by compressed air. The piston, pos. 21, is pushed into the lower end position of the filling tube, pos. 30, with the aid of the pneumatic cylinder. By the drawn ;. Seal on the piston, pos. 21, the space E is completely sealed off from the mold space.
3. Auswerfen; .Nach der Versinterung bzw. der Verschäumung der einzelnen Perlen mit Hilfe von Dampf sowie nach der Abkühlung des jetzt entstandenen Schäumlings wird die Form geöffnet. Der Schäumling bleibt nun auf der Seite der Form hängen, auf der die Füllgeräte mit Auswerfer angesetzt sind. Jetzt wird der Raum F, der während des ganzen Prozesses unter Druckluft stand, über die Schlauchverschraubung, Pos. 4, enttüftet. Gleichzeitig ist aber der Raum G über dem Schlauchanschluß, Pos. 4,- mit Preßluft beaufschlagt. Dadurch schiebt der pneumatische Kolben, Pos, 10, den schwimmenden Kolben, Pos. 58, nach vorne. Dadurch wird wiederumder Verschlußkolben, Pos. 21, aus dem . Füll rohr hinausgeschoben. Durch dieses Hinausschieben wird der Schäumling aus seiner Form herausgeschoben. Dieses Herausschieben des Formkörpers (Schäumling) wird in der Praxis mit Auswerfer Bezeichnet., 3. eject; After the sintering or foaming of the individual beads with the aid of steam and after the foam that has now been formed has cooled down, the mold is opened. The foam now remains hanging on the side of the mold on which the filling devices with ejector are attached. Now space F, which was under compressed air during the entire process, is vented via the hose screw connection, item 4. At the same time, however, the space G above the hose connection, item 4, is acted upon with compressed air. This causes the pneumatic piston, pos. 10, to push the floating piston, pos. 58, forward. This in turn makes the sealing piston, pos. 21, out of the. Filling tube pushed out. This pushing out pushes the foam out of its shape. This pushing out of the molded body (foam) is referred to in practice as an ejector.,
