Verfahren zur Herstellung einer Verbindung zwischen zwei ExtrusionsprofilteilenMethod for producing a connection between two extrusion profile parts
Die Erfindung betrifft ein Verfahren der im Oberbegriff des Patentanspruchs 1 genannten und aus der DE 698 17 834 T2 bekannten ArtThe invention relates to a method referred to in the preamble of claim 1 and known from DE 698 17 834 T2 Art
Es ist bekannt, Extrusionsprofilteile mittels Formecken zu verbinden, indem an die glatten Endbeschnitte der Profilteile, die in ein Einspritzwerkzeug eingeschoben werden, das eingespritzte Kunststoffmaterial angespritzt wird Hierfür werden die Beschnittenden der Profilteile gerade oder mit versetzten Konturen ausgebildet, an welchen das eingespritzte Kunststoffmateπal ausreichend haftet Diese Verbindungsart wird häufig bei Extrusionsprofilteilen aus künstlich hergestelltem Gummi (EPDM) angewendet Dabei wird als Material für die Formecken ebenfalls häufig kunstlich hergestellter Gummi verwendet, weil identische Materialien eine gute Haftverbindung ergeben Aus bestimmten Gründen wäre als Material für die Formecken jedoch ein thermoplastisches Elastomer (TBE) von Vorteil Einspritzecken aus einem thermoplastischen Elastomer haben gegenüber solchen aus künstlich hergestelltem Gummi unter anderem den Vorteil einer geringeren Fertigungstaktzeit, wodurch weniger Werkzeuge benotigt werden Infolge geringerer Innendrucke im Einspritzwerkzeug kommt es auch zu geringeren Austrieben, was die Versauberungsarbeit erleichtert Außerdem besteht bei Formecken aus einem thermoplastischen Elastomer die Möglichkeit, Profile mit kunststoffahnhchen Gleitschichten, die Vorteile bei der Bewegung von anliegenden Glasscheiben haben, an den Verbindungen zu verarbeiten Aus einem thermoplastischen Elastomer hergestellte Formecken haben allerdings den Nachteil einer geringen Haftkraft an Profilteilen aus künstlich hergestelltem Gummi Darüber hinaus nimmt die Haftkraft bei Warmebeaufsch lagung deutlich ab Stoßverbindungen zwischen einem Profilteil aus künstlich hergestelltem Gummi und einer Formecke aus thermoplatischem Elastomer sind daher nicht dauerhaftIt is known to connect extrusion profile parts by means of Formecken by the injected plastic material is injected onto the smooth Endbeschnitte the profile parts which are inserted into an injection tool For this, the Beschnittenden the profile parts are formed straight or with staggered contours to which the injected Kunststoffmateπal sufficiently liable This type of connection is often used for extruded profile parts made of synthetic rubber (EPDM). Artificial rubber is also often used as the material for the mold corners, because identical materials give a good bond. For certain reasons, however, a thermoplastic elastomer (TBE) would be used as the material for the mold corners Advantageous Einspritzecken of a thermoplastic elastomer have over those of artificially manufactured rubber, inter alia, the advantage of a lower production cycle time, whereby fewer tools needed As a result of lower internal pressures in the injection tool, it also comes to lower sprouts, which facilitates the Verauberungsarbeit In addition, form corners made of a thermoplastic elastomer has the ability to process profiles with plastic-thin sliding layers, which have advantages in the movement of adjacent glass panes, on the connections thermoplastic elastomer Form corners, however, have the disadvantage of a low adhesive force on profile parts made of synthetically manufactured rubber In addition, the adhesive force in Warmebeaufsch lagging significantly From butt joints between a profile part of man-made rubber and a form corner of thermoplastic elastomer are therefore not durable
Der Erfindung liegt die Aufgabe zugrunde, das gattungsgemaße Verfahren dahingehend weiterzubilden daß Stoßverbindungen zwischen Profilteilen aus künstlich hergestelltem Gummi (EPDM) und Formecken aus einem thermoplatischen Elastomer (TPE) mit einer über einen großen Temperaturbereich ausreichenden Dauerfestigkeit ausgeführt werden könnenThe invention has the object of developing the generic method to the effect that butt joints between profile parts of man-made rubber (EPDM) and form corners of a thermoplastic elastomer (TPE) can be performed with sufficient over a wide temperature range fatigue strength
Die Losung dieser Aufgabe ist im Patentanspruch 1 angegebenThe solution of this problem is specified in claim 1
Dadurch, daß vor dem Anordnen der Extrusionsprofilteile in der Form an der Innenseite ihrer Endbereiche Hmterschneidungen ausgebildet werden, kann eine formschlussige Verbindung zwischen den Profilteilen und dem die Formecke bildenden eingespritzten Kunststoffmateπal erzielt werden Infolge dieser formschlussigen Verbindung sind die Profilteile nach dem Ausharten des Kunststoffmateπals gegen ein Abziehen von der Formecke zulassig geschützt Diese formschlussige Verbindung wird auch nicht durch eine Warmebeaufschlagung beeinträchtigtCharacterized in that prior to arranging the extrusion profile parts in the form on the inside of their end portions Hmterschneidungen be formed, a formschlussige connection between the profile parts and the forming corner forming injected Kunststoffmateπal be achieved as a result of this formschlussigen connection the profile parts after curing of Kunststoffmateπals against a Removed from the mold corner Permitted protected This form-fitting connection is not affected by a heat application
Der erfinderische Grundgedanke kann in herstellungstechnisch vorteilhafter Weise verwirklicht werden, indem in den Endbereichen der Extrusionsprofilteile durch geeignete Gestaltung des Extrusionsprofils Vorsprunge gebildet werden, oder indem durch Stanzen oder Bohren Durchbruche gebildet werdenThe inventive concept can be realized in manufacturing technology advantageously by protrusions are formed in the end regions of the extrusion profile parts by suitable design of the extrusion profile, or by breakthroughs are formed by punching or drilling

Wie bereits eingangs erwähnt werden bei dem bekannten Verfahren zur Herstellung einer Verbindung die beiden Extrusionsprofilteile 1 , 2 an den Enden beschnitten und sodann in einer Form bzw in einem Einspritzwerkzeug 3 in der gewünschten Konfiguration angeordnet Bei dem gezeigten Ausfuhrungsbeispiel sind die beiden Profilteile 1 , 2 rechtwinklig zueinander angeordnet, es sind aber auch alle anderen Winkelstellungen möglich Die beiden Profilteile 1 , 2 sind durch Extrudieren von kunstlich hergestelltem Gummi (EPDM) erzeugt In das Einspritzwerkzeug 3 wird sodann ein verflüssigtes thermoplastisches Elastomer (TPE) eingespritzt, das die Endbereiche der beiden Profilteile auf der Innenseite überdeckt Das aushärtende Kunststoffmateπal bildet eine als Formecke 4 bezeichnete Verbindung zwischen den Endbereichen der beiden Profilteile 1 , 2 Nach dem Ausharten des Kunststoffmateπals können die miteinander verbundenen Profilteile 1 , 2 aus dem Einspritzwerkzeug 3 entnommen werden Das vorstehend geschilderte Verfahren ist herkömmlich und bedarf daher keiner näheren ErläuterungAs already mentioned in the known method for producing a connection, the two extrusion profile parts 1, 2 are trimmed at the ends and then arranged in a mold or in an injection tool 3 in the desired configuration In the illustrated embodiment, the two profile parts 1, 2 are rectangular The two profile parts 1, 2 are produced by extrusion of artificially produced rubber (EPDM) in the injection mold 3 then a liquefied thermoplastic elastomer (TPE) is injected, which the end portions of the two profile parts The hardening Kunststoffmateπal forms a designated Form corner 4 connection between the end portions of the two profile parts 1, 2 After curing of Kunststoffmateπals the interconnected profile parts 1, 2 are removed from the injection mold 3 Das vor standing described method is conventional and therefore needs no further explanation
Zur Verbesserung der Haftung zwischen den Profilteilen und der von dem ausgeharteten Kunststoffmateπal gebildeten Formecke 4 ist vorgesehen, daß vor dem Anordnen der Profilteile 1 , 2 in dem Einspritzwerkzeug 3 an der Innenseite ihrer Endbereiche Hmterschneidungen ausgebildet werden Bei dem in den Fig 2 und 3a gezeigten Ausfuhrungsbeispiel werden diese Hmterschneidungen von Ausschnitten oder Offnungen 5 gebildet, die durch Stanzen oder Bohren in den Profilteilen 1 , 2 gebildet sind Wie aus dem in Fig 3a gezeigten Schnitt hervorgeht, dringt das Kunststoffmateπal in die Öffnungen 5 ein und füllt diese aus Dadurch kommt es zu einer mechanischen Verkrallung zwischen dem Kunststoffmatenal und den Profilteilen Durch den sich hierdurch ergebenden Formschluß können die bei der Montage oder durch Schrumpfung entstehenden Zugkräfte besser übertragen werden und die Haftverbindung zwischen der Formecke 4 und den Extrusionsprofilteilen 1 und 2 wird entlastetTo improve the adhesion between the profile parts and formed by the cured Kunststoffmateπal Formecke 4 is provided that before arranging the profile parts 1, 2 are formed in the injection mold 3 on the inside of their end portions Hmterschneidungen In the exemplary embodiment shown in Figures 2 and 3a These cutouts are formed by cutouts or openings 5 which are formed by stamping or drilling in the profile parts 1, 2. As can be seen from the section shown in FIG. 3a, the plastic material penetrates into the openings 5 and fills them mechanical Verkrallung between the Kunststoffmatenal and the profile parts By the resulting positive engagement, the resulting during assembly or shrinkage tensile forces transmitted better be and the adhesive bond between the mold corner 4 and the extrusion profile parts 1 and 2 is relieved
In Fig 3b ist eine Abwandlung gezeigt, bei der die Hinterschneidungen von Vorsprungen 6 gebildet werden, die in das Innere der Profilteile 1 und 2 hineinragen Diese Vorsprunge 6 können beispielsweise durch geeignete Gestaltung des Extrusionsprofils erzeugt werdenIn Fig 3b, a modification is shown, in which the undercuts of projections 6 are formed, which protrude into the interior of the profile parts 1 and 2 These projections 6 can be produced for example by suitable design of the extrusion profile
