Erfindungsgemäß ist das Kernstück (7) zur Entformung zerlegbar und in Teilstücken (8–10) durch die Öffnung (13) hindurch bewegbar.The invention relates to a molding tool for injecting a molded part (4) onto at least one end of a sealing strand, in particular at ends (2, 3) of sealing strands (1) which are at an angle to one another, the molded part (4) having a tubular, possibly corresponding to the angle Bent sealing section (6) which is connected to a tubular sealing section of the sealing strand (1) or connects tubular sealing sections (5) of the sealing strands (1), and the molding tool comprises a core piece (7) forming the inside of the tubular sealing section (6) which can be moved for demolding through an opening (13) in the tubular sealing section (6) of the molded part (4). According to the invention, the core piece (7) can be dismantled for demolding and can be moved in sections (8-10) through the opening (13).
Description
Die Erfindung betrifft ein Formwerkzeug zum Anspritzen eines Formteils an zumindest ein Ende eines Dichtungsstrangs, wobei das Formteil einen schlauchförmigen, Dichtungsabschnitt aufweist, welcher sich beim Anspritzen mit einem schlauchförmigen Dichtungsabschnitt des Dichtungsstrangs verbindet, und wobei das Formwerkzeug ein den schlauchförmigen Dichtungsabschnitt innenseitig formendes Kernstück umfasst, das zur Entformung durch eine Öffnung in dem schlauchförmigen Dichtungsabschnitt des Formteils hindurch bewegbar ist. The invention relates to a molding tool for molding a molded part on at least one end of a sealing strip, wherein the molded part has a tubular, sealing portion which connects to a tubular sealing portion of the sealing strip during injection molding, and wherein the molding tool comprises a core piece forming the tubular sealing section on the inside, which is for removal through an opening in the tubular sealing portion of the molded part is movable therethrough.
Beim Anspritzen des Formteils an den Dichtungsstrang bzw. die Dichtungsstränge entsteht ein durchgehend schlauchförmiger Dichtungsabschnitt. Zur Entformung, d.h. zum Entfernen des Kernstücks aus dem durch das Kernstück durchgehend gebildeten Schlauch, bedarf es daher der genannten Öffnung, die im Hinblick auf nachträgliches Verschließen jedoch möglichst klein zu halten ist. Beim Bewegen des Kernstücks durch die Öffnung hindurch kommt es zu erheblicher Dehnung des soeben gespritzten Formteils sowie der Dichtungsstränge, und es besteht die Gefahr von Beschädigungen. When the molded part is injection-molded onto the sealing strip or the sealing strands, a continuous tubular sealing section is produced. For demolding, i. To remove the core from the tube continuously formed by the core piece, therefore, it requires the said opening, which is to be kept as small as possible in terms of subsequent closure. When moving the core through the opening, there is considerable elongation of the molded part just sprayed and the sealing strands, and there is a risk of damage.
Der Erfindung liegt die Aufgabe zugrunde, ein neues Formwerkzeug der eingangs genannten Art zu schaffen, das eine erhöhte Fertigungssicherheit ermöglicht.The invention has for its object to provide a new mold of the type mentioned, which allows an increased manufacturing security.
Das diese Aufgabe lösende Formwerkzeug nach der Erfindung ist dadurch gekennzeichnet, dass das Kernstück zur Entformung zerlegbar und in Teilstücken durch die Öffnung hindurch bewegbar ist. The solving this task mold according to the invention is characterized in that the core piece for demolding is separable and movable in sections through the opening.
Vorteilhaft sind durch die erfindungsgemäße Zerlegbarkeit des Kernstücks in Teilstücke starke Dehnungsbeanspruchungen insbesondere des Formteils vermieden und die Gefahr von Beschädigungen ist verringert. Advantageously, due to the dismantling of the core piece according to the invention into sections, strong expansion stresses, in particular of the molded part, are avoided and the risk of damage is reduced.
Zweckmäßig lassen sich Teilstücke zur Entformung durch die Öffnung hindurch unter geringstmöglicher Dehnung des Formteils nacheinander nach außen befördern.It is expedient for pieces to be conveyed outwards through the opening with the least possible elongation of the molded part in order to remove it from the mold.
Vorzugsweise ist das Formwerkzeug zum Anspritzen eines Eckenformteils an zueinander im Winkel stehende Dichtungsstränge vorgesehen, wobei der schlauchförmige Dichtungsabschnitt des Eckenformteils entsprechend dem Winkel gebogen ist und schlauchförmige Dichtungsabschnitte der Dichtungsstränge miteinander verbindet. Preferably, the molding tool for molding a corner molding is provided to each other at an angle sealing strip, wherein the tubular sealing portion of the corner molding is bent according to the angle and tubular sealing portions of the sealing strands together.
In einer besonders bevorzugten Ausführungsform der Erfindung umfasst das Kernstück zumindest drei Teilstücke. In a particularly preferred embodiment of the invention, the core piece comprises at least three sections.
Ein Teilstück, z.B. ein Mittelteil, kann gegen die übrigen Teilstücke unter Bewegung durch die Öffnung hindurch verschiebbar sein. Vorteilhaft entsteht durch die Verschiebung ein Freiraum, in den die übrigen Teilstücke sukzessive nachrücken und von dem aus sie durch die Kernentformungsöffnung hindurch nach außen bewegt werden können.A section, e.g. a central part, may be displaceable against the remaining sections while moving through the opening. Advantageously, a free space is created by the displacement, in which the other sections successively move up and from which they can be moved out through the Kernentformungsöffnung to the outside.
Bei der Öffnung handelt es sich vorzugsweise um eine Schlitzöffnung, die durch einen Haltesteg gebildet ist, welcher das Kernstück mit einer Kernstückhalterung verbindet und während des Spritzvorgangs in der erforderlichen Position hält. The opening is preferably a slot opening formed by a retaining web which connects the core piece to a core piece holder and holds it in the required position during the injection process.
Zweckmäßig ist auch der Haltesteg entsprechend dem Kernstück in Stegabschnitte unterteilt.Suitably, the retaining web is divided according to the core piece in web sections.
Vorzugsweise ist der Haltesteg so angeordnet, dass die entstehende Schlitzöffnung entlang der Innenseite des gebogenen schlauchförmigen Dichtungsabschnitts des Eckenformteils verläuft. Preferably, the retaining bar is arranged so that the resulting slot opening extends along the inside of the curved tubular sealing portion of the corner molding.
Wenigstens einer der Stegabschnitte, insbesondere ein mit dem verschiebbaren Teilstück verbundener Stegabschnitt, kann mit einem bei der Entformung zu betätigenden Schieber verbunden sein. At least one of the web sections, in particular a web section connected to the displaceable section, can be connected to a slide to be actuated during demolding.
Das verschiebbare Teilstück ist mit den übrigen Teilstücken z.B. über eine Schwalbenschwanzführung verbunden, welche die Teilstücke einerseits zusammenhält und andererseits die Verschiebung des genannten Teilstücks gegenüber den anderen Teilstücken ermöglicht. The displaceable section is connected to the remaining sections e.g. connected via a dovetail guide, which holds the parts together on the one hand and on the other hand allows the displacement of said portion relative to the other sections.
In einer weiteren Ausführungsform der Erfindung sind die Teilstücke untereinander unverlierbar verbunden, z.B. über flexible Stränge. In a further embodiment of the invention, the sections are captively connected to each other, e.g. over flexible strands.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels und der beiliegenden, sich auf dieses Ausführungsbeispiel beziehenden Zeichnungen weiter erläutert.
