Description

Die Erfindung bezieht sich auf eine Vorrichtung zur liarstellung von Kunstharzpreßmischungen, insbesondere von Preßmischungen, die härtbares Kunstharz oder härtbare Kunstharzkompositionen enthalten. The invention relates to a device for visualization of synthetic resin molding compounds, especially molding compounds, the curable synthetic resin or contain curable synthetic resin compositions.

Solche Vorrichtungen besitzen eine Schnecke, durch die das Ausgangsmaterial unter Erwärmen zusammengedrückt und einer Stelle, z. B. einem aus sich gegeneinander drehenden Teilen gebildeten Ringspalt, zugeleitet wird, an der die Mischung und Umhüllung der Teilchen bei hoher Temperatur beendet wird. Such devices have a screw through which the starting material pressed together with heating and a place, z. B. one against each other rotating parts formed annular gap, is fed to which the mixture and Envelopment of the particles at high temperature is completed.

Bei glatter Ausbildung der Innenwand des Schneckengehäuses, das beheizt sein kann, wird die Rohmasse von der rotierenden Schnecke mitgenommen, so daß die Verdichtung und die Förderung derselben beeinträchtigt werden. With a smooth construction of the inner wall of the screw housing, which heats can be, the raw mass is taken from the rotating screw, so that the Compaction and the promotion of the same are impaired.

Wenn diesem Übelstand durch Anbringung von Rillen in dem Gehäuse, z. B. achsparalleler Rillen, begegnet wird, so wird zwar die Masse infolge der Reibung festgehalten, jedoch ergibt sich der Nachteil, daß sie sich leicht mit Masse zusetzen kann, so daß die Wirkung verlorengeht. Außerdem rufen sie, namentlich wenn viele solche Rillen vorhanden sind, einen raschen Verschleiß der gesamten Gehäusewand hervor, so daß nach kurzer Zeit der Zylinder bzw. d-ie Zylinderbüchse unrund wird und ausgewechselt werden muß. If this disadvantage by making grooves in the housing, z. B. axially parallel grooves is encountered, although the mass is due to the friction noted, but there is the disadvantage that they are easily clogged with mass so that the effect is lost. They also call out, especially when there are many Such grooves are present, a rapid wear of the entire housing wall so that after a short time the cylinder or the cylinder liner becomes out of round and needs to be replaced.

Die Erfindung schlägt nun vor, an der inneren Gehäusewandung Stege anzubringen, vorzugsweise achsparallel. Nach einer bevorzugten Ausführungsform werden die Stege auswechselbar ausgebildet durch die Anordnung von Nuten, in die die Stege eingesehoben werden. Diese Stege werden so angebracht, daß ihre höchste Fläche oder Kante dicht an den Schneckengängen anliegen. The invention now proposes webs on the inner housing wall to be attached, preferably axially parallel. According to a preferred embodiment the webs formed interchangeably by the arrangement of grooves in which the webs be collected. These bars are attached so that their highest surface or Edge close to the worm threads.

In der Zeichnung ist eine bevorzugte Ausführungsform der Vorrichtung der Erfindung im Querschnitt dargestellt. Das Gehäuse I der Schnecke 5 ist mit auswechselbaren achsparallelen Stegen 4 verstehen. Die Zahl der Stege ist beliebig, ebenso ihre Form. In the drawing is a preferred embodiment of the device the invention shown in cross section. The housing I of the screw 5 is interchangeable understand axially parallel webs 4. The number of bars is arbitrary, as is yours Shape.

Ein Mitnehmen der Masse durch die Schneckengänge kann mit Sicherheit vermieden werden. und es wird eine Schonung der Innenwand des Gehäuses erreicht. Es kann für die Stege ein besonders widerstandsfähiges Material verwendet werden. Taking the mass with you through the worm flights can be sure be avoided. and the inner wall of the housing is protected. A particularly resistant material can be used for the bars.
