DuroplastdüseDuroplast nozzle
BeschreibungDescription
Das Gebrauchsmuster betrifft eine Duroplastdüse mit einem zentralen Düsenkanal und etwa radial ausgrichteten Angußkanälen im Düsenkopf.The utility model relates to a thermoset nozzle with a central nozzle channel and approximately radially aligned sprue channels in the nozzle head.
Eine Duroplastdüse ist auf vergleichsweise niedrige Temperatur temperiert, damit die Duroplastmasse nicht in der Duroplastdüse aushärtet. In Stillstandzeiten, bei einem Werkzeugwechsel, bei einem Wechsel der Duroplastmasse, z.B. einem Farbwechsel oder dergleichen kommt es zu Aushärtungen in der Düse. Auch zu Reinigungszwecken und für Wartungsarbeiten muß die Düse von Zeit zu Zeit gereinigt werden. Dieses erfordert den Ausbau der Düse aus den Werkzeugplatten. Die Arbeiten sind jedenfalls sehr zeitaufwendig.A thermosetting plastic nozzle is heated to a relatively low temperature so that the thermosetting plastic mass does not harden in the thermosetting plastic nozzle. During downtimes, when changing tools, when changing the thermosetting plastic mass, e.g. when changing the color or similar, hardening occurs in the nozzle. The nozzle must also be cleaned from time to time for cleaning purposes and for maintenance work. This requires the nozzle to be removed from the tool plates. In any case, the work is very time-consuming.
Aufgabe des Gebrauchsmusters ist die Bereitstellung einer einfach und schnell zu reinigenden Duroplastdüse.The purpose of the utility model is to provide a thermoset nozzle that is easy and quick to clean.
Diese Aufgabe wird nach dem Gebrauchsmuster dadurch gelöst, daß eine Kappe des Düsenkopfes rinnenförmige Wandungsteile der Angußkanäle bildet und lösbar angeordnet ist.This problem is solved according to the utility model in that a cap of the nozzle head forms channel-shaped wall parts of the sprue channels and is arranged detachably.
Das Gebrauchsmuster unterscheidet sich insofern vom Stand der Technik, als die Kappe ein öffnen der Angußkanäle und damit ein Herausnehmen des Angusses ermöglicht. Die Kappe kann von der Schließebene des Werkzeugs aus gehandhabt werden, so daß ein Ausbau des Düsenkopfes nicht notwendig ist. Normalerweise wird der Anguß beim Herausnehmen der Kappe mit herausgezogen.The utility model differs from the state of the art in that the cap allows the sprue channels to be opened and the sprue to be removed. The cap can be handled from the closing plane of the tool, so that it is not necessary to remove the nozzle head. The sprue is normally pulled out when the cap is removed.
Ein vorteihaftes Herausnehmen des Angusses ist dadurch möglich, daß die Angußkanäle geneigt zur Achse des Düsenkanals ausgerichtet sind.Advantageous removal of the sprue is possible because the sprue channels are aligned at an angle to the axis of the nozzle channel.

Eine Betätigung der Kappe von der Rückseite der Duroplastdüse ist derart möglich, daß die Kappe durch axiale Befestigungsschrauben befestigt ist.The cap can be operated from the back of the thermoset nozzle as the cap is secured by axial fastening screws.
Die Handhabung der Duroplastdüse wird dadurch erleichtert, daß die Kappe einen Ansatz für ein Haltewerkzeug aufweist.The handling of the thermoset nozzle is made easier by the fact that the cap has an attachment for a holding tool.
Ein Ausführungsbeispiel des Gebrauchsmusters wird anhand der Zeichnung erläutert, in der darstellen:An embodiment of the utility model is explained using the drawing, which shows:
Fig. 1 einen Axialschnitt in der Ebene von Angußkanälen,Fig. 1 an axial section in the plane of sprue channels, Fig. 2 eine Draufsicht zu Fig. 1 undFig. 2 is a plan view of Fig. 1 and
Fig. 3 einen Axialschnitt senkrecht zur Ebene der Fig. 1.Fig. 3 is an axial section perpendicular to the plane of Fig. 1.
Die Duroplastdüse umfaßt einen im wesentlichen zylindrischen Körper 1 mit einem Ringansatz 2 zum Einbau in eine nicht dargestellte düsenseitige Werkzeugplatte. Zentral innerhalb des Körpers 1 verläuft ein Düsenkanal 3, der in zwei V-förmig zueinander angeordnete Angußkanäle 4 endet. Man kann auch eine größere Anzahl von sternförmig angeordneten Angußkanälen vorsehen.The thermosetting plastic nozzle comprises a substantially cylindrical body 1 with a ring attachment 2 for installation in a tool plate (not shown) on the nozzle side. A nozzle channel 3 runs centrally within the body 1 and ends in two sprue channels 4 arranged in a V shape relative to one another. A larger number of sprue channels arranged in a star shape can also be provided.
Die Angußkanäle 4 sind in ihrer Längsrichtung aufgetrennt. Eine etwa linsenförmige Kappe 5 des Kopfes der Duroplastdüse schließt die Angußkanäle ab und bildet jeweils rinnenförmige Wandungsteile der Angußkanäle 4. Die Kappe 5 weist zwei achsparallele Gewindebohrungen 6 auf, in die Befestigungsschrauben 7 eingreifen, die durch den Körper 1 reichen. Zentral in der Stirnfläche der Kappe 5 ist ein Ansatz 8 z.B. in Form einer Gewindebohrung ausgebildet, der ein Haltewerkzeug z.B. in Form einer Schraube aufnimmt.The sprue channels 4 are split in their longitudinal direction. An approximately lens-shaped cap 5 of the head of the thermosetting plastic nozzle closes off the sprue channels and forms channel-shaped wall parts of the sprue channels 4. The cap 5 has two axially parallel threaded holes 6 into which fastening screws 7 engage, which extend through the body 1. Centrally in the front surface of the cap 5 there is a projection 8, e.g. in the form of a threaded hole, which accommodates a holding tool, e.g. in the form of a screw.
Außerdem sind in üblicher Weise Temperierkanäke 9 vorhanden, die an einen Temperiermittelkreislauf angeschlossen sind, was im Einzelnen nicht erläutert wird.In addition, there are usually temperature control channels 9 which are connected to a temperature control medium circuit, which is not explained in detail.
Zu Wartungs- oder Reparturarbeiten wird nach dem Auffahren des Werkzeugs ein Haltewerkzeug z.B. eine Schraube in die Gewindebohrung 8 eingeschraubt. Dann werden die Befestigungsschrauben 7 gelöst. Man kann nun die an dem Haltewerkzeug sitzende Kappe 5 abziehen. Dabei wird der Anguß normalerweise bereits herausgezogen. Für diese Watungsarbeiten bleibt die Duroplastdüse in der düsenseitigen Werkzeugplatte eingebaut. Die notwendigen Arbeiten können sämtlich im Einbauzustand der Duroplastdüse durchgeführt werden.For maintenance or repair work, a holding tool, e.g. a screw, is screwed into the threaded hole 8 after the tool has been moved up. The fastening screws 7 are then loosened. The cap 5 on the holding tool can now be pulled off. The sprue is usually already pulled out. For this maintenance work, the duroplastic nozzle remains installed in the nozzle-side tool plate. All of the necessary work can be carried out while the duroplastic nozzle is installed.
