Das Zubehör-10 to receive hoses, for example, and to attach accessories to the outer surface of the hollow body thus obtained, which serve, for example, to attach, connect or handle the hollow body itself. The accessories-

Diese Nachbearbeit ng beträgt daher einen Transport innerhalb eines Betriebes bis zur15 element can be welded, glued or screwed onto the hollow body, which means processing outside the blow molding machine. This post-processing is therefore a transport within a company to

Das Zubehörelement selbst, wenn es beispielsweise eine Befestigungslasche des Hohlkörpers aus Kunststoff sein sollte, ist an einer20 welding or assembly device to join the accessory element with the hollow body. The accessory element itself, if it should be, for example, a fastening tab of the hollow body made of plastic, is on one
25 Spritzgussmaschine herzustellen: es ist deshalb die Verwendung einer solchen, getrennten Maschine erforderlich, was weitere Vorbereitungsund Rüstzeiten verursacht.25 injection molding machine: it is therefore necessary to use such a separate machine, which causes additional preparation and set-up times.
30 Aus der deutschen Veröffentlichung DE 199 20 601 ist eine S chne 1 Iwechs el e inr i cht ung an einem Extruder bekannt, bei der dieser letztere einen Anschlus s flansch aufweist, an dem verschiedene Bearbeitungseinrichtungen zur weiteren Bearbeitung des Hohlkörpers rasch befestigt und ausgetauscht werden können. Wenn auch eine derartige Einrichtung eine Bearbeitung unmittelbar am Extruder ermöglicht, kann diese Weiterbearbeitung nur nach Öffnung der Blasform und daher außerhalb derselben erfolgen.From the German publication DE 199 20 601, a screwing device on an extruder is known, in which the latter has a connection flange on which different Machining devices for further processing of the hollow body can be quickly attached and replaced. If such a device also enables processing directly on the extruder, this further processing can only take place after the blow mold has been opened and therefore outside of it.
Die Aufgabe der vorliegenden Erfindung liegt daher darin, die oben angegebenen Probleme des Standes der Technik zu lösen und ein Verfahren, eine Blas- und Spritzform von Kunststoffartikeln und so erhaltene Artikel vorzuschlagen, die mit kürzeren Arbeit s abl aufen , mit geringe- rem Aufwand von Arbeitskräften und mit einer hohen Bea rbe itungs quäl i tat ausführbar sind.The object of the present invention is therefore to solve the above-mentioned problems of the prior art and to propose a method, a blow and injection mold of plastic articles and articles obtained in this way, which run with shorter work s, with less effort of Workforce and with a high processing quality.
Diese und weitere Aufgaben werden in einem Verfahren und einer Blas- und Spritzform von Kunststoffartikeln und so erhaltenen Artikel durch die Merkmale der Kennzeichen der entsprechenden Ansprüche gelöst.These and other objects are achieved in a method and a blow and injection mold of plastic articles and articles obtained in this way by the features of the characteristics of the corresponding claims.
Mit dem Vorschlag, einen "Külbel" aus einem Extruder zu extrudieren, den "Külbel" in einer Blasform zu blasen und in einem Nest in der Blasform, das mit dem Hohlraum der Blasform ü- ber einen Fließkanal kommuniziert, Schmelzmaterial einzuspritzen und den Bl a s z eitpunkt mit dem Einspritzzeitpunkt zu koordinieren, kann der mit dem Zubehörelement versehene Hohlkörper in einem einzigen Arbe it s ablauf der Maschine mit einer hohen Qualität des Produktes hergestellt werden.With the suggestion to extrude a "parison" from an extruder, to blow the "parison" in a blow mold and in a nest in the blow mold, which communicates with the cavity of the blow mold via a flow channel, to inject melt material and to blow the blow The hollow body provided with the accessory element can be coordinated with the injection point in a single workflow of the machine be manufactured with a high quality of the product.
In einer erfindungsgemäß ausgeführten Form sind ein, das Zubehörel ement wiedergebende Nest, ein mit einem über einen Trichter mit Kunststoff gespeisten Spr i t z zy1 inder verbundenen Kunststoff sprit z kanal und ein Durchlass ausgenommen, der mit der Wand des extrudierten Hohlkörpers kommuniziert, die sich durch Druck an der Wand des Hohlraumes anschmiegt. Es ist klar, dass für den Auszug des Zubehörelement e s aus der Form in Anwesenheit von Hinter s chne idungen in der Form zweckmäßige Schieber vorzusehen sind, welche die Hinter s chneidungen umgehen.In a form designed in accordance with the invention, a nest representing the accessory element, a plastic injection channel connected to a fuel injector zy1 fed via a funnel with plastic, and a passage which communicates with the wall of the extruded hollow body, which communicates through pressure, are excluded hugs the wall of the cavity. It is clear that for the removal of the accessory element from the mold in the presence of undercuts in the mold, suitable pushers are to be provided which bypass the undercuts.
In einer bevorzugten Aus führ ngs form ist zur Vermeidung von Schiebern, beispielsweise für Befestigungslaschen an 'Schläuchen ein Teil bzw. die Hälfte des Nestes in einer der Formhälften und der andere Teil bzw. die andere Hälfte in der anderen Formhälfte ausgenommen.In a preferred embodiment, part or half of the nest in one of the mold halves and the other part or the other half in the other mold half is excluded to avoid slides, for example for fastening tabs on hoses.
In einer Variante ist der Einspr i t z ana 1 zwi- sehen der Trennfläche der beiden Formhälften gebildet .In one variant, the injection ana 1 is formed between the separating surface of the two mold halves.
