Abstract

Apparatus for carrying out multicomponent injection-moulding processes, in particular two-component injection-moulding processes, characterized in that one or more further plastifying unit(s) has/have been integrated in the mould.

Description

Werkzeugintegrierte Plastifiziereinheit Tool-integrated plasticizing unit

Die Erfindung betrifft eine Vorrichtung zur Durchführung von Mehrkomponentenspritzgussverfahren, insbesondere Zweikomponenten- spritzgussverfahren.The invention relates to a device for carrying out multicomponent injection molding, in particular two-component injection molding.

Für die Durchführung von Mehrkomponentenspritzgussverfahren sind bisher aufwändige Spritzgussmaschinen erforderlich, die je nach Zahl der Komponenten entsprechende Plastifiziereinheiten und Formteile aufweisen.To carry out multicomponent injection molding processes, elaborate injection molding machines have hitherto been required which, depending on the number of components, have corresponding plasticizing units and molded parts.

Aufgabe der Erfindung war es, ein konventionelles Spritzgusswerkzeug derart auszurüsten, dass auch eine zweite oder mehrere Komponente auf einer einfachen Gußmaschine verarbeitet werden kann.The object of the invention was to equip a conventional injection molding tool such that a second or more component can be processed on a simple casting machine.

Gegenstand der Erfindung ist daher eine Vorrichtung zur Durchführung von Mehrkomponentenspritzgussverfahren, insbesondere Zweikomponenten- spritzgussverfahren, dadurch gekennzeichnet, dass im Werkzeug eine oder mehrere weitere Plastifiziereinheit(en) integriert ist(sind).The invention therefore relates to an apparatus for carrying out multicomponent injection molding processes, in particular two-component injection molding processes, characterized in that one or more further plasticizing unit (s) is (are) integrated in the tool.

Die Plastifiziereinheit kann dabei ein konventionelles Spritzaggregat mit Schnecke, Kolben oder ein Hot-Melt Applikator sein. Das Plastifiziermodul kann daher eine einfache Bauweise aufweisen, wobei das Modul an das Schussgewicht der zur verarbeitenden Formmasse angepasst werden kann. Besonders bevorzugt wird als Plastifiziereinheit ein Spritzaggregat mit Schnecke verwendet.The plasticizing unit may be a conventional injection unit with screw, piston or a hot-melt applicator. The plasticizing module can therefore have a simple construction, wherein the module can be adapted to the shot weight of the molding compound to be processed. It is particularly preferable to use an injection unit with a screw as the plasticizing unit.

Bei Mehrkomponentenspritzgussmaschinen ist eine derartige Anpassung nicht oder nur sehr aufwändig möglich.In the case of multicomponent injection molding machines, such an adaptation is impossible or only possible with great difficulty.

Das Plastifiziermodul ist in das Werkzeug integriert und kann bei entsprechender Dimensionierung im Kern eingebaut werden. Die Temperierung kann durch die Maschinensteuerung erfolgen oder getrennt über eine externe Temperaturregelung, wobei sowohl geheizt als auch gekühlt werden kann.The plasticizing module is integrated in the tool and can be installed in the core with appropriate dimensioning. The temperature control can be done by the machine control or separately via an external temperature control, which can be both heated and cooled.

Die notwendigen Bewegungen der Plastifizeireinheit können hydraulisch, pneumatisch oder elektrisch gesteuert werden.The necessary movements of the plastifizir unit can be controlled hydraulically, pneumatically or electrically.

Durch die ins Werkzeug integrierte zusätzliche Plastifiziereinheit bzw. mehrere Plastifiziereinheiten können mehrere unterschiedliche Formmassen getrennt oder gleichzeitig verarbeitet werden.By integrated into the tool additional plasticizing or more plasticizing several different molding compounds can be processed separately or simultaneously.

Dadurch können auf einfache Weise beispielsweiseThis allows a simple way, for example

Oberflächenbeschichtungen, reaktive Materialien, wie geschäumte Massen, Dichtungen und dergleichen in einem Arbeitsgang aufgebracht werden. Es ist auch möglich Formmassen unterschiedlicher Farbe in einem Arbeitsgang zu verarbeiten, wobei auch nur Teilbereiche in einer anderen Farbe ausgeführt werden.Surface coatings, reactive materials, such as foamed masses, seals and the like can be applied in one operation. It is also possible to process molding compositions of different colors in one operation, whereby only partial areas are executed in a different color.

Ferner können auch reaktive Massen, beispielsweise auch Einkomponentensystem verarbeitet werden, wobei über die werkzeugintegrierte Plastifiziereinheit der Initiator eingebracht werden kann und die Vernetzung in der Form erfolgt.Furthermore, it is also possible to process reactive masses, for example one-component systems, wherein the initiator can be introduced via the tool-integrated plasticizing unit and the crosslinking takes place in the mold.

In Fig. 1 ist eine erfindungsgemäße Vorrichtung dargestellt, darin bedeuten 1 das Werkzeug, 2 die zusätzliche Plastifiziereinheit und 3 die Plastizifiereinheit der Spritzgussmaschine. 1 shows a device according to the invention, in which 1 the tool, 2 the additional plasticizing unit and 3 the plasticizing unit of the injection molding machine.
