Abstract
Description
Die Erfindung betrifft einen Dreh- oder Querschieberverschluss mit einem Steuerschieber zum Öffnen und Schließen einer von einem Medium in einer Richtung durchströmten Leitung, insbesondere einer Einspritzdüse einer Spritzgießmaschine, welcher in einem die Leitung kreuzenden Führungskanal beweglich angeordnet ist und in Abhängigkeit von seiner Position die Leitung entweder öffnet oder verschließt.The The invention relates to a rotary or cross-slide closure with a Control slide to open and closing a conduit through which a medium flows in one direction, in particular an injection nozzle an injection molding machine, which arranged in a conduit crossing the guide channel movable is and depending either opens or closes the line from its position.
Bei
derartigen Dreh- oder Querschieberverschlüssen müssen zwei gegensätzliche
Bedingungen erfüllt
werden: Einerseits sollte das Spiel zwischen dem Steuerschieber
und dem umgebenden Gehäuse
so groß sein,
dass der Steuerschieber relativ leicht innerhalb des Führungskanals
beweglich bleibt und es vor allem bei raschen Schließ- bzw. Öffnungsbewegungen
nicht zu einem mechanischen Fressen kommt; andererseits muss das
Spiel jedoch so gering sein, dass das in der Leitung strömende Medium
nicht in den Spalt zwischen Schieber und Gehäuse eindringen kann. Im allgemeinen
wird dieses technische Problem durch elastische Dichtungen zwischen
dem Steuerschieber und dem Gehäuse
im Bereich des Führungskanals
gelöst.
Bei hohen Temperaturen und hohen Drücken können jedoch derartige Dichtungen
nicht eingesetzt werden. Bei Spritzgießmaschinen, insbesondere bei
sogenannten Spritzgießcompoundern,
mit solchen Dreh- oder Querschieberverschlüssen (
Es ist Aufgabe der vorliegenden Erfindung, einen Verschlussmechanismus mit einem Dreh- oder Querschieber der eingangs genannten Art zu schaffen, der auch bei hohen Drücken und Temperaturen, wie sie zum Beispiel in Spritzgießmaschinen herrschen, dauerhaft und sicher öffnet und schließt.It The object of the present invention is a locking mechanism with a rotary or transverse slide of the type mentioned above create, even at high pressures and temperatures, such as those in injection molding machines prevail, permanently and safely opens and close.
Diese Aufgabe wird durch einen Dreh- oder Querschieberverschluss nach den Merkmalen des Patentanspruchs 1 bzw. 3 oder 6 gelöst.These Task is by a rotary or cross slide lock after the features of claim 1 or 3 or 6 solved.
Der Steuerschieber des erfindungsgemäßen Dreh- oder Querschieberverschlusses wird in der Schließlage mit einer der Strömungsrichtung in der Leitung entgegengesetzt gerichteten Druckkraft beaufschlagt, wodurch der auf den Steuerschieber durch das in der Leitung strömende Medium ausgeübte Druck kompensiert und der Steuerschieber zusätzlich gegen die zu verschließende Seite der Leitung gedrückt wird. Dadurch wird selbst bei hohen Drücken in der Leitung verhindert, dass in der Schließlage des Steuerschiebers eine einlassseitige Vergrößerung des Spiels im Führungskanal zwischen dem Steuerschieber und dem umgebenden Gehäuse auftritt.Of the Control slide of the rotary or cross slide closure is in the closed position with one of the flow direction applied in the line oppositely directed pressure force, whereby the on the spool by the flowing medium in the conduit practiced Pressure compensated and the spool additionally against the side to be closed pressed the line becomes. This prevents even at high pressures in the line, that in the closed position of the spool an inlet side enlargement of the game in the guide channel occurs between the spool and the surrounding housing.
In vorteilhafter Ausführung der Erfindung sind im Bereich des Führungskanals auf beiden Seiten der Leitung Lagerflächen zur Abstützung des Steuerschiebers vorgesehen, durch welche dieser bei einem Übergang in die Schließlage eine Verschiebung entgegen der Strömungsrichtung in der Leitung erfährt. Diese Lagerflächen können mit einem mechanischen, hydraulischen oder elektrischen Antrieb verbunden sein, mittels welchem in der Schließlage des Steuerschiebers eine Druckkraft auf den Steuerschieber entgegen der Strömungsrichtung in der Leitung erzeugt wird.In advantageous embodiment The invention are in the region of the guide channel on both sides the line storage areas for support the spool provided by which this at a transition in the closed position a shift against the flow direction in the pipe experiences. These storage areas can with a mechanical, hydraulic or electric drive be connected, by means of which in the closed position of the spool a Pressure force on the spool against the direction of flow in the line is generated.
Spezielle Ausführungsbeispiele eines Dreh- bzw. Querschieberverschlusses sind in den Figuren teilweise stark schematisiert dargestellt und werden im folgenden näher beschrieben. Es zeigen:Specific embodiments a rotary or cross slide closure are partially in the figures shown in a highly schematic manner and will be described in more detail below. Show it:
