Abstract

The elastic inflatable sealing cord (1) for forming tools, in particular, for production of vehicle interior components consisting of plastic materials with several components comprises an end section (3) which has a turned-in wall and is closed by means of an end piece (2) joined to the end section by vulcanization.

Description

Elastische aufblasbare Dichtungsschnur für Formwerkzeuge,Elastic inflatable sealing cord for molds, insbesondere zur Herstellung von Fahrzeuginnenteilenespecially for the production of vehicle interior parts

Die Erfindung betrifft eine elastische aufblasbare Dichtungsschnur nach dem Oberbegriff des Anspruches 1.The invention relates to an elastic inflatable sealing cord according to the preamble of claim 1.

Eine derartige Dichtungsschnur ist aus dem Gebrauchsmuster 201 10 950 bekannt. Die Erfindung ist auf eine derartige bekannte Dichtungsschnur gerichtet, die ebenso in die in diesem Gebrauchsmuster beschriebenen Formwerkzeuge einbaubar ist.Such a sealing cord is known from the utility model 201 10 950. The invention is directed to such a known sealing cord, which can also be installed in the molds described in this utility model.

Der Erfindung liegt die Aufgabe zugrunde eine derartige bekannte Dichtschnur zu schaffen, deren Ende auch bei hoher Beanspruchung sicher verschlossen ist.The invention is based on the object of creating such a known sealing cord, the end of which is securely closed even under high stress.

Diese Aufgabe wird durch das Kennzeichen des Anspruches 1 gelost.This problem is solved by the characterizing part of claim 1.

Dadurch, daß das eine verschlossene Ende umgebördelt ist entsteht in Längsrichtung der Dichtschnur ein großer Bereich, der zum vulkanisieren zur Verfügung steht. Das einvulkanisierte Endstück weist eine entsprechende Länge auf. Diese großen Vulkanisationsflächen sorgen für einen sicheren Verschluß, bei dem nicht die Gefahr einer unerwünschten Beschädigung besteht.Because one of the closed ends is flanged, a large area is created in the longitudinal direction of the sealing cord that is available for vulcanization. The vulcanized end piece has a corresponding length. These large vulcanization surfaces ensure a secure closure with no risk of unwanted damage.

In vorteilhafterweise handelt es sich um eine Dichtschnur mit kreisrundem Querschnitt, die die einfachste und am günstigsten herzustellende Form darstellt. Selbstverständlich sind auch andere Querschnittsformen wie rechteckig, oval oder quadratisch möglich.It is advantageous to have a sealing cord with a circular cross-section, which is the simplest and cheapest shape to produce. Of course, other cross-sectional shapes such as rectangular, oval or square are also possible.

In der einzigen Figur ist ein Längsschnitt eines Endes einer aufblasbaren Dichtschnur nach der Erfindung dargestellt.The single figure shows a longitudinal section of one end of an inflatable sealing cord according to the invention.

Die Dichtschnur 1 ist an dem einen Ende bei 3 umgebördelt. In den offenen verbleibenden Querschnitt ist ein Endstück 2 eingesetzt. Die Teile sind entsprechend durch Vulkanisieren dicht und dauerhaft miteinander verbunden.The sealing cord 1 is flanged at one end at 3. An end piece 2 is inserted into the remaining open cross-section. The parts are sealed and permanently connected to one another by vulcanization.

Es ist erkennbar, daß sich das Endstück und der umgebördelte Bereich in Längsrichtung der Dichtschnur über einen verhältnismäßig langen Abschnitt erstreckt. Hierdurch steht eine große Fläche zum Vulkanisieren zur Verfügung, so daß für einen sicheren und dauerhaften Verschluß gesorgt ist.It can be seen that the end piece and the flanged area extend over a relatively long section in the longitudinal direction of the sealing cord. This provides a large area for vulcanization, ensuring a secure and permanent seal.
