Description

Bei der Herstellung von geformten Gegenständen in Spritzgußmaschinen für thermoplastische Kunststoffe oder Metalle wird der Arbeitsstoff in abgemessenen Mengen einem Spritzzyhnder zugeführt. In the manufacture of molded objects in injection molding machines for thermoplastics or metals, the working material is measured in Quantities fed to a spray cylinder.

Die bisher bekanntgewordenen Maschinen sind aber nur in der Lage, Arbeitsstoffe gleicher Art oder Farbe für jedes Arbeitsspiel dem Arbeitszylinder zuzuführen, es sei denn, daß in den Einfülltrichter ein bereits vorgemischter Arbeitsstoff eingefüllt wird.The machines that have become known so far are only able to Working materials of the same type or color for each work cycle the working cylinder to be added, unless there is an already premixed substance in the feed hopper is filled.

Die Erfindung besteht darin, daß verschiedenfarbiges oder verschiedenartiges Arbeitsgut in beliebigen einstellbaren Mengen aus zwei oder mehr Dosiervorrichtungen gemeinsam der Form einer Spritzgußmaschine zugeführt wird. The invention consists in that different colored or different types Work goods in any adjustable quantities from two or more dosing devices is fed together to the mold of an injection molding machine.

Eine für die Ausübung des neuen Verfahrens geeignete Spritzgußmaschinetbesitzt zwei oder mehr Einfülltrichter für die Aufnahme und Abgabe verschiedenfarbigen oder verschiedenartigen Arbeitsguts, die mit einem gemeinsamen Vorfüllraum verbunden sind, in welchem entsprechend viele Schieber oder Kolben angeordnet sind, die in Abhängigkeit vom Spritzkolben bewegt werden. Die Einfülltrichter selbst können ein- oder mehrfach unterteilt sein, wodurch sich die Anzahl der Mischungsmöglichkeiten erhöht. Zur Verbesserung der Mischwirkung können im Vorfüllraum und/oder zwischen diesem und dem Spritzzylinder Leitbleche für das Arbeitsgut vorgesehen sein. Have an injection molding machine suitable for practicing the new process two or more funnels for receiving and dispensing different colored or different types of work, which are connected to a common pre-filling space are, in which a corresponding number of slides or pistons are arranged, which in Be moved depending on the injection plunger. The funnel itself can be or be subdivided several times, which increases the number of possible combinations elevated. To improve the mixing effect, in the pre-filling space and / or between this and the injection cylinder baffles are provided for the work piece.

Nach dem Verfahren gemäß der Erfindung ist es z. B. möglich, aus verschiedenfarbiger Kunststoffmasse marmorierte Formteile herzustellen, ohne daß die verschiedenen Stoffe vorher außerhalb der Maschine gemischt werden müssen. Außerdem ist man in der Lage, den Anteil der verschiedenen Stoffe schnell und ohne großen Aufwand zu ändern. Das Verfahren läßt sich aber auch zum Dosieren und Mischen von flüssigen Metallen zur Herstellung von Formteilen aus Metallen verwenden. According to the method according to the invention it is e.g. B. possible from different colored plastic mass to produce marbled molded parts without the different substances have to be mixed outside the machine beforehand. aside from that one is able to determine the proportion of different substances quickly and without major Effort to change. The method can also be used for dosing and mixing Use liquid metals to manufacture molded parts from metals.

In der Zeichnung ist eine Spritzgußmaschine zur Ausübung des Verfahrens gemäß Erfindung schematisch dargestellt. In the drawing is an injection molding machine for performing the method shown schematically according to the invention.

Mit a und b sind Einfülltrichter bezeichnet, die zur Aufnahme und Abgabe von beispielsweise verschiedenfarbigen, pulverförmigen, körnigen oder flüssigen Kunststoffen c und d dienen. Mit e ist ein Vorfüllraum bezeichnet, dessen Schieber oder Kolben f und g durch bekannte Mittel in Abhängigkeit von dem Spritzkolben bewegt werden, der im Sprirtzzylinder h geführt ist und das Mischgut in bekannter Weise der Form zuführt. With a and b hopper are designated for receiving and Dispensing of, for example, different colored, powdery, granular or liquid Plastics c and d are used. A prefill space is designated with e, its slide or pistons f and g moved in response to the injection piston by known means which is guided in the spray cylinder h and the mix in a known manner feeds the mold.

PATENTANSPROCHE: I. Verfahren zum Dosieren und Mischen pulverförmigen, körnigen oder flüssigenArbeitsguts, z. B. thermoplastischer Kunststoffe oder Metalle in Spritzgußmaschinen, dadurch gekennzeichnet, daß verschiedenfarbiges oder verschiedenartiges Arbeitsgut in beliebigen einstellbaren Mengen aus zwei oder mehr Dosiervorrichtungen gemetusam der Form einer Spritzgußmaschine zugeführt wird. PATENT CLAIM: I. Process for dosing and mixing powdery, granular or liquid work items, e.g. B. thermoplastics or metals in injection molding machines, characterized in that different colored or different types Work goods in any adjustable quantities from two or more dosing devices is fed to the mold of an injection molding machine.
