Abstract
Description
Die Erfindung betrifft einen extrudierten Dichtungsstrang zur Verbindung mit einem an ein Ende des Dichtungsstrangs anzugießenden Dichtungsteil, insbesondere mit einem Eckenverbindungsstück.The invention relates to an extruded sealing strip for connection to a sealable part to be attached to an end of the sealing strip, in particular with a corner joint piece.
Dichtungen, insbesondere Dichtungen zur Abdichtung von Fenstern an Fahrzeugen, lassen sich häufig nicht durchgehend aus einem extrudierten Strang herstellen. Zum Beispiel für Eckenbereiche sind gesonderte, mit Enden von Dichtungssträngen zu verbindende Dichtungsteile erforderlich.Seals, in particular gaskets for sealing windows on vehicles, can often not be made continuously from an extruded strand. For example, for corner areas, separate sealing parts to be joined with ends of sealing strands are required.
Bei der Herstellung der Dichtungsteile nach dem Spritzgießverfahren sind die mit dem Dichtungsteil zu verbindenden Strangenden in eine Gießform einzuführen. Hierbei kommt es darauf an, dass die Strangenden innerhalb der Gießform maßgenau die für die Verbindung mit dem Dichtungsteil vorgesehene Position einnehmen.In the production of the sealing parts by the injection molding process, the strand ends to be joined with the sealing part are to be introduced into a casting mold. It is important that the strand ends within the casting mold accurately measure the intended position for the connection with the sealing part.
Der Erfindung liegt die Aufgabe zugrunde, die Herstellung solcher aus Dichtungssträngen und Dichtungsteilen bestehender Verbunddichtungen zu vereinfachen.The invention has for its object to simplify the production of such sealing strips and sealing parts existing composite seals.
Diese Aufgabe wird durch einen Dichtungsstrang gelöst, der dadurch gekennzeichnet ist, dass er Anschlageinrichtungen zur Festlegung eines mit dem Dichtungsteil zu verbindenden Strangteils innerhalb einer Gießform für das Dichtungsteil aufweist.This object is achieved by a sealing strip which is characterized in that it comprises stop means for fixing a strand part to be connected to the sealing part within a casting mold for the sealing part.
Vorteilhaft erleichtern die erfindungsgemäßen Anschlageinrichtungen eine präzise Platzierung der Strangenden innerhalb der Spritzgießform. Es versteht sich, dass die Spritzgießform den Anschlageinrichtungen entsprechende Gegenelemente und ggf. eine zu den Anschlageinrichtungen komplementäre Gießforminnenwand aufweist.The stop devices according to the invention advantageously facilitate precise placement of the strand ends within the injection mold. It is understood that the injection mold has counter-elements corresponding to the stop devices and possibly a casting mold inner wall which is complementary to the stop devices.
Insbesondere sind Anschlageinrichtungen zur Festlegung des Strangteils in einer Richtung quer zur Stranglängsrichtung vorgesehen.In particular, stop devices are provided for fixing the strand part in a direction transverse to the strand longitudinal direction.
Es versteht sich, dass die genannten Anschlageinrichtungen einen Vorsprung oder/und eine Vertiefung umfassen können.It will be appreciated that said stop means may comprise a projection and / or a recess.
Vorzugsweise ist der Vorsprung oder/und die Vertiefung über die gesamte Länge des Dichtungsstrangs durchgehend mitextrudiert.Preferably, the projection and / or the recess is continuously extruded over the entire length of the sealing strip.
In einer besonders bevorzugten Ausführungsform der Erfindung handelt es sich bei dem festzulegenden Strangteil um eine Dichtungslippe, die zum Strangende hin isoliert vorsteht, d. h. die übrigen Strangteile sind in diesem Endabschnitt entfernt worden. Die Dichtungslippe ist entlang ihrer Längsseite an das Dichtungsteil anzugießen.In a particularly preferred embodiment of the invention, the strand part to be defined is a sealing lip projecting in isolation to the strand end, i. H. the remaining strand parts have been removed in this end section. The sealing lip is to be cast along the longitudinal side of the sealing part.
Vorzugsweise ist der Vorsprung oder/und die Vertiefung auf einer Seite der Dichtungslippe gebildet, die der zu Anlage gegen ein abzudichtendes Objekt vorgesehenen Seite abgewandt ist.Preferably, the projection and / or the recess is formed on one side of the sealing lip, which faces away from the intended for abutment against an object to be sealed side.
Der genannte Vorsprung kann selbst lippenartig ausgebildet sein und vorzugsweise schräg von der Dichtungslippe vorstehen, so dass vorteilhaft eine Festlegung der Lippe innerhalb der Gießform durch Verhakung erfolgen kann.Said projection may itself be formed like a lip and preferably project obliquely from the sealing lip, so that advantageously a determination of the lip can be done within the mold by entanglement.
In einer weiteren Ausführungsform der Erfindung geht das angegossene Dichtungsteil in Stranglängsrichtung bündig in die Außenkontur des Strangs über.In a further embodiment of the invention, the cast-on sealing part merges flush in the longitudinal direction of the strand into the outer contour of the strand.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels und der beiliegenden, sich auf dieses Ausführungsbeispiel beziehenden Zeichnung weiter erläutert. Es zeigen:The invention will be explained below with reference to an embodiment and the accompanying, referring to this embodiment drawing. Show it:
