     Vor Inbetriebsetzung der Vorrichtung   werden die Ventilstangen jener Düsen, durch   die da   Schmelzgut austreten soll, mit der Platte 9 gekuppelt. Die Bunde der gekuppelten Stangen stehen   quf   zu den Schlitzen, die Bunde der ändern in der Richtung der Schlitze. Nachdem die Form 13 an di Düsen angesetzt worden ist, wird die. Platte 9 gesenkt und das Schmelzgut unter Druck gesetzt.   BI   dem dargestellten Ausführungsbeispiel geschieht dies mittels des Kolbens 4 ; es kann aber statt des Kolben auch ein flüssiges oder gasförmiges Druckmittel zur Anwendung kommen. Durch Heben der Platte werden sodann die Ventile geschlossen ; schliesslich-wird die Form gehoben und entleert. 



   Beim Übergang auf ein anders geformtes Gussstück ist es nur notwendig, eine neue Auswahl de in Wirkung tretenden Ventile zu treffen. Ein Austausch von Elementen der Maschine ist nicht erforderliel Gegebenenfalls kann jedes Ventil noch mit einer Verankerungseinrichtung ausgestattet sein, um ei unbeabsichtigtes Öffnen der nicht gekuppelten Ventile zu verhindern. 



   PATENT-ANSPRÜCHE :-   l.     spritzgussmaschine   für Kunststoffe, dadurch gekennzeichnet, dass, ein mit   Innenbeheizung   
 EMI2.1 
   einem Vorratsbehälter (3) in Verbindung steht und dass der Druck mittels eines Kolbens oder eine flüssigen. oder gasförmigen Druckmittels. auf das im Vorratsbehälter befindliche Material zur Wirkun   gebracht wird.

     Before the device is put into operation, the valve rods of those nozzles through which the molten material is to emerge are coupled to the plate 9. The collars of the coupled rods stand quf to the slots, the collars of the others in the direction of the slots. After the mold 13 has been attached to the nozzles, the. Plate 9 is lowered and the melt is pressurized. BI the illustrated embodiment, this is done by means of the piston 4; however, a liquid or gaseous pressure medium can also be used instead of the piston. The valves are then closed by lifting the plate; Finally, the mold is lifted and emptied.



   When changing to a differently shaped casting, it is only necessary to make a new selection of the valves that come into effect. It is not necessary to replace elements of the machine. If necessary, each valve can also be equipped with an anchoring device in order to prevent unintentional opening of the uncoupled valves.
