Description
Die Erfindung betrifft eine Vorrichtung zur Herstellung von mehrkomponentigen Kunststoff-Formteilen, insbesondere von Kunststoff-Formteilen aus einer ersten spritzgegossenen Komponente und einer zweiten flüssigen Lack- bzw. Überflutungskomponente.The The invention relates to a device for producing multicomponent Plastic moldings, in particular of plastic moldings a first injection molded component and a second liquid component Paint or flooding component.
Es ist bekannt, dass sich beim Lackieren bzw. Überfluten von spritzgegossenen Kunststoff-Formteilen zum Aufbringen einer Beschichtung der Anspritzpunkt auf derjenigen Seite des fertigen Formteils befindet, auf der sich die lackierte bzw. überflutete Oberfläche befindet. Dabei kann es zur Ausbildung von unerwünschten Markierungen auf der Oberfläche der Beschichtung kommen.It is known that when painting or flooding of injection molded plastic moldings for applying a coating of Injection point is located on the side of the finished molding, on the varnished or flooded surface located. This can lead to the formation of unwanted Markings come on the surface of the coating.
Aus
der
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, diese bekannte Vorrichtung weiterzuentwickeln und weitere Funktionen zu integrieren.Of the present invention is based on the object, these known Further develop the device and integrate additional functions.
Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruchs 1. Weiterentwicklungen finden sich in den Merkmalen der Unteransprüche.The This object is achieved by the features of the claim 1. Further developments can be found in the features of the subclaims.
Erfindungsgemäß ist eine Multifunktions-Nadelverschlussdüse vorgesehen, deren Verschlussnadel neben einer Offen- und einer Geschlossenstellung in weitere Stellungen verfahrbar ist, wobei die Verschlussnadel wenigstens in eine in das Werkzeug hineinragende Stellung verfahrbar ist, in der die Verschlussnadel als Werkzeugkern dient und dabei in einer Kunststoffkomponente nach ihrem Rückzug einen Kanal hinterlässt, und wobei die Verschlussnadel zum Ausstoßen der fertigen Kunststoff-Formteile vorgesehen ist. Mit ein und derselben Nadelverschlussdüse können somit mehrere Funktionen und Aufgaben erfüllt werden. Es wird kein separater Werkzeugkern benötigt, um eine Ausnehmung, insbesondere einen Kanal in einer ersten Komponente zu erzeugen. Des Weiteren kann auf separate Auswerfer verzichtet werden.According to the invention a multifunction needle valve nozzle is provided, whose Valve needle in addition to an open and a closed position in further positions is movable, wherein the valve pin at least in a projecting into the tool position movable is, in which the valve needle serves as a tool core and thereby in a plastic component after their withdrawal one Channel leaves, and where the valve pin to eject the finished plastic molded parts is provided. With one and the same Needle valve nozzle can thus have multiple functions and tasks are fulfilled. It does not become a separate tool core needed to a recess, in particular a channel in a first component. Furthermore, can on separate Ejector be waived.
Das Werkzeug ist vorteilhafterweise als Spritzprägewerkzeug ausgebildet und die Verschlussnadel kann in ihrer Funktion als Werkzeugkern durch die Kavität hindurchragen und beim Prägevorgang mitbewegt werden. Hierbei kann die Verschlussnadel federkraftbeaufschlagt an einer Formhälfte auf Anschlag stehen und beim Prägevorgang entgegen der Federkraft zurückbewegt werden.The Tool is advantageously as injection compression tool trained and the valve needle can in their function as a tool core protrude through the cavity and the embossing process be moved. In this case, the valve needle can be spring-loaded on a mold half to stop and opposite to the stamping process the spring force are moved back.
Für das Einbringen der ersten Komponente des mehrkomponentigen Kunststoff-Formteils in das Werkzeug kann eine separate Materialzufuhr vorgesehen sein, zum Beispiel ein separater Heißkanal oder eine Angussbuchse. Die Multifunktions-Nadelverschlussdüse ist dann nur zum Einbringen der nächsten Komponente in das Werkzeug und durch die erste Komponente hindurch vorgesehen.For the introduction of the first component of the multi-component plastic molding a separate material supply can be provided in the tool, for example, a separate hot runner or sprue bushing. The multifunction needle valve nozzle is then only for Introducing the next component into the tool and provided through the first component.
Insbesondere bei der Herstellung einer Lack- oder Überflutungsschicht auf einer ersten Kunststoff-Komponente kann es vorteilhaft sein, dass die der Multifunktions-Verschlussdüse zugeordnete Formhälfte des Werkzeugs einen Bereich mit einem umlaufenden zylindrischen oder mit einer Entformungsschräge versehenen Absatz (Tauchkante) aufeist, insbesondere wenn erforderlich einen Bereich mit einer umlaufenden Hinterschneidung, und dass die Verschlussnadel in dem von dem Absatz bzw. der Hinterschneidung umfassten Bereich der Formhälfte in das Werkzeug hineinverfahrbar ist. Damit kann die Trennebene zwischen dem Formteil bzw. der ersten Komponente des Formteils und dem Kanal für das Lack- oder Überflutungsmaterial besser abgedichtet werden.Especially in the production of a paint or flooding layer on a first plastic component it may be beneficial that the mold half associated with the multi-function shut-off nozzle of the tool an area with a circumferential cylindrical or with a draft angle provided paragraph (dipping edge) in particular, if necessary, an area with a circumferential undercut, and that the shutter needle in the from the paragraph or the undercut included area of the mold half in the tool is movable. Thus, the dividing plane between the molding or the first component of the molding and the channel better for the paint or flooding material be sealed.
