Der Extruder 2 weist einen Strangpreßkopf 7 mit einer Düse 8 auf»The extruder 2 has an extrusion head 7 with a Nozzle 8 on »
Nach der Erfindung wird die Öffnungszeit der Spritzgußform 4, 5 ausgenützt, um in die Schließebene der Spritzgußform eine Umhüllung 9 einzubringen die beispielsweise Von einer Folie oder einer Hülle gebildet wird, die von dem Extruder als Strang durch die Düse 8 hinfe durchgepreßt wirde According to the invention, the opening time of the injection mold 4, 5 is used to introduce an envelope 9 into the closing plane of the injection mold, which is formed, for example, from a film or envelope that is pressed through the extruder as a strand through the nozzle 8 e
Wie es die Fig. 3 bis 5 zeigen, wird die Folie 9 ßun der Stelle 10 beim Schließen der Spritzgußform eingeklemmt und abgeschnitten und danach nach einem an sich bekannten Vorfahren verformt« Die Verformung kann beispielsweise durch Erwärmen der Folie und Anwendung von Vakuum oder Druck erfolgen« Wenn es sich bei der Umhüllung 9 um eine Hülle handelt, kann sie beispielsweise durch Aufblasen mit Hilfe eines beweglichen oder festen Blasstempels oder einer Blasnadel in die gewünschte Form gebracht werden. Die Perforation der Hülle „rau der oder den Stellen, an denen dann das Einspritzen erfolg't, W . kann auf verschiedene Weise bewirkt werden«As FIGS. 3 to 5 show, the film 9 is clamped and cut off at the point 10 when the injection mold is closed and then deformed according to a known method. The deformation can be done, for example, by heating the film and applying vacuum or pressure If the envelope 9 is an envelope, it can be brought into the desired shape, for example by inflating it with the aid of a movable or fixed blow die or a blow needle. The perforation of the casing "rough at the point (s) at which the injection then takes place", W. can be effected in different ways «
lele
Ist die Folie 9 in. die gewünschte Form gebracht (Fig. 5)» spritzt die Spritzgußmaschine den Kunststoff, beispielsweise einen Schaumkunststoff, durch die Einspritzdüse 11 der Form ein und es beginnt die Abkühlphase des ge.gp27.itston Gegenstandes. Nach der Abkühlung wird der gegossene Gegenstand ausgestoßen, der bei dem gewählten Beispiel aus einem Schaumkunststoff besteht, der mit einer Folie aus einem thermoplastischen, liomogegen Kunststoff, bedeckt ist.Is the film 9 brought into the desired shape (Fig. 5) » the injection molding machine injects the plastic, for example a foam plastic, through the injection nozzle 11 the shape and the cooling phase of the ge.gp27.itston begins Subject. After cooling, the cast object is ejected, which in the example chosen is from consists of a foam plastic, which is covered with a film made of a thermoplastic, liomogegen plastic is.

Nach dem Offnen der Spritzgußform kann der beschriebene Zyklus von neuem beginnen«After the injection mold has been opened, the cycle described can begin again «
Ea sei bemerkt, daß die Folie 9 auch unmittelbar mit Hilfe der eingespritzten Masse geformt werden kann, wenn das Einspritzen schnell genug nach dem Einklemmen der Folie 9 erfolgt.Ea it should be noted that the film 9 also directly with Help the injected mass can be molded if the injection is fast enough after clamping the Slide 9 takes place.
Fig. 6 zeigt eine Maschine mit mehreren Stationen, bei der das erfindungsgemäße Verfahren angewendet wird. Die verschiedenen Spritzgußformen 4-, 5» äie sich auf dem Drehtisch 12 befinden, Öffnen' sich in der claii Extruder zugeordnetenStellung« Nachdem dor gespritzte Gegenstand ausgestoßen ist, bleibt die Form offen und- es wird die durch die Düse 8 hindurch extrudierte Folie zwischen die beiden Teile der Form eingeführt. Die Formteile schließen sich wieder, klemmen die Folie am Rande ein und schneiden sie ab. Nach der Formung läuft der Drehtisch um einen Schritt weiter und bringt die Form vor die Spritzgußmaschine 1, die den Schaumkunststoff einspritzt· Während der folgenden Schritte hat der gespritzte Gegenstand Zeit zum Abkühlene Wenn der Drehtisch die betrachtete Form wieder vor den Extruder 2 bringt, wird die Form geöffnet und es beginnt der beschriebene Zyklus von neuem zur Herstellung eines folgenden Gegenstandes.6 shows a machine with several stations in which the method according to the invention is applied. The various injection molds 4, 5 "are located on the turntable 12, open in the position associated with the extruder" introduced both parts of the mold. The molded parts close again, clamp the film at the edge and cut it off. After shaping the turntable goes one step further and brings the form, the injection molding machine 1, which injects the plastic foam · In the following steps, the to cool e When the turntable brings sprayed subject of time looking at the form again in front of the extruder 2, the mold is opened and the cycle described begins again for the production of a subsequent object.
Ea versteht sich, daß gemäß den Prinzipien einer Spritz» gußma3chine mit mehreren Formstationen der Extruder Jeder geeigneten Station zugeordnet werden kann« Dabei kann der Extruder kontinuierlich oder schrittweise arbeitend ausgebildet sein.It goes without saying that according to the principles of a spray » casting machine with several molding stations of the extruder each suitable station can be assigned «The extruder can be designed to work continuously or in steps be.
