Description

Vorrichtung zur Herstellung von Lagerbüchsen u. dgl. aus härtbaren Kunstharzmassen Die Erfindung betrifft eine Vorrichtung zum Herstellen von Lagerbuchsen, Stangen und rohrförmigen Körpern verschiedener Profile aus härtbaren Kunstharzmassen durch Aneinanderfügen des Preßgutes in Teilmengen mit Hilfe des Preßstempels, der am Ende des Rückhubes die Verbindung zwischen dem Formhohlraum und einem Fülltrichter freigibt. Eine ähnlich arbeitende Vorrichtung ist zum Herstellen von Profilsträngen bereits bekannt, und zwar ist bei dieser die Matrize waagerecht liegend angeordnet und der Fülltrichter ~ oben auf dem Mantel der Matrize über einer von dem Preßstempel gesteuerten Zuführungsöffnung aufgesetzt. Diese Anordnung ist jedoch nur brauchbar zur Verarbeitung von pulverförmigem oder feinkörnigem Ausgangsmaterial, beispielsweise Kunstharzpreßnzassen mit Holzmehlfüllung, weiches leicht aus dem Zuführungstrichter nachfließt. Bei dieser Anordnung ist es aber unmöglich, ein aus imprägnierten Leinenschnitzeln bestehendes Ausgangsmaterial zu verarbeiten, wie es für die Herstellung yon Lagerschalen benötigt wird, da dessen Struktur dem freien Ausfließen aus dem Fülltrichter außerordentlich hinderlich wäre und eine gleichmäßige Verteilung grober Pießmassen um den Kern der Form hier nicht gewährleistet Wäre, insbesondere dann, wenn die Wandungen nur gering sind.Device for the production of bearing bushes and the like from hardenable Synthetic resin compositions The invention relates to a device for producing bearing bushes, Rods and tubular bodies of various profiles made from hardenable synthetic resin compounds by joining the pressed material in partial quantities with the help of the ram, the at the end of the return stroke the connection between the mold cavity and a filling funnel releases. A similarly working device is for the production of profile strands already known, namely in this the die is arranged horizontally and the hopper - on top of the mantle of the die above one of the ram controlled feed opening placed. However, this arrangement is only useful for processing powdery or fine-grained starting material, for example Kunstharzpreßnzassen with wood flour filling, soft slightly from the feed hopper flows in. With this arrangement, however, it is impossible to use impregnated linen shreds to process existing raw material as it is for the manufacture of bearing shells is needed, as its structure is extraordinarily good for the free flow out of the hopper would be a hindrance and an even distribution of coarse skewers around the core of the Shape would not be guaranteed here, especially if the walls are only small are.

Erfindungsgemäß wird nun vorgeschlagen, die Preßform senkrecht stehend anzuordnen und den Fülltrichter an der oberen Stirnseite der Form, den hohlen, an dem Kernzapfen der Form geführten Preßstempel umgebend, vorzusehen. Diese Anordnung gibt die Möglichkeit, auch s,chwer nachrutschendes Schnitzelmaterial' einwandfrei zur Rohrform u. dgl. zu verpressen, da der Preßstempel bei seinem Abwärtsgang den Preßstoff auf den ganzen Umfang gleichmäßig verteilt in den Ringraum der Form hineinschiebt. Ein weiterer Vorteil der neuen Anordnung ist der, daß die Form annähernd bis zu ihrem oberen Rande ausgenutzt werden kann. According to the invention it is now proposed that the mold stand vertically to arrange and the hopper on the upper end of the mold, the hollow surrounding the core pin of the mold guided press ram, to be provided. This arrangement makes it possible to use even hard-to-slip cossette material To be pressed properly to the pipe shape and the like, since the ram is on its way down the molding material evenly distributed over the entire circumference in the annular space of the mold pushes in. Another advantage of the new arrangement is that the shape is approximate can be used up to its upper edge.

Um die Wärmebeeinflussung des Preßstoffes in dem Fülltrichter von dem beheizten Formmantel her gering zu halten, wird der Fülltrichter unter Zwischenlagerung eines isolierenden Ringes auf die Form aufgesetzt. To the influence of heat on the molding material in the hopper of To keep the heated mold jacket low, the hopper is placed in interim storage an insulating ring placed on the mold.
