Abstract
Description
Die Erfindung richtet sich auf ein Verfahren und eine Vorrichtung zur Herstellung von Minen für Kosmetikstifte oder dergleichen, wobei die Mine in eine Hülse eingegossen wird, die in eine Form eingelegt ist, und wobei die flüssige Gießmasse in der Hülle bzw. in der Form erstarrt.The invention relates to a method and an apparatus for manufacturing of leads for cosmetic pencils or the like, the lead in a sleeve is poured, which is inserted into a mold, and wherein the liquid casting compound solidifies in the shell or in the mold.
Ein derartiges Verfahren ist aus dem deutschen Patent 38 35 680 bekannt. Bei dem bekannten Verfahren besteht die Hülse aus einem Kunststoff-Formteil nach Art eines Röhrchens, welches längs seiner Mantelfläche einen Schlitz aufweist und in eine horizontale Halteeinrichtung derart eingelegt wird, daß eine durchgehende Stirnplatte der Halteeinrichtung die Kunststoff-Formteile so abdeckt, daß lediglich deren Schlitz zum Einfüllen der Minengießmasse freibleibt. Durch ein derartiges horizontales Gießen wird zwar eine optimale Minenstruktur erreicht, jedoch ist die Arbeitsgeschwindigkeit nicht zufriedenstellend.Such a method is known from German Patent 38 35 680. In the known method, the sleeve consists of a molded plastic part in the manner of a tube, which has a along its lateral surface Has slot and inserted in such a horizontal holding device is that a continuous end plate of the holding device Plastic molded parts so that only their slot for filling the mine casting compound remains free. By such horizontal casting an optimal mine structure is achieved, but the working speed is not satisfactory.
Die DE 40 16 474 beschreibt ein Verfahren und eine Vorrichtung, wonach vorgesehen ist, daß die mit Gießmasse zu füllenden Hülsen drehantreibbar gelagert sind und die fließfähige Masse aus einem Vorratsbehälter heraus unter Einwirkung der Zentrifugalkraft in die Hülsen gedrückt wird.DE 40 16 474 describes a method and a device according to which it is provided that the sleeves to be filled with casting compound can be driven in rotation are stored and the flowable mass out of a storage container is pressed into the sleeves under the influence of centrifugal force.
Aus DE 27 18 957 C3 und DE 40 05 894 A1 ist es bekannt, die Minenmasse über eine Gießdüse vom rückwärtigen Ende der vertikal gelagerten Hülse in diese einzufüllen. Dabei ergeben sich insbesondere bei vergleichsweise langen bzw. dünnen Hülsen Probleme dadurch, daß man dafür Sorge tragen muß, daß in der Hülse keine Lufteinschlüsse entstehen, d.h. es muß eine Möglichkeit eröffnet werden, damit die Luft während des Gießvorganges abströmen kann.From DE 27 18 957 C3 and DE 40 05 894 A1 it is known the lead mass via a pouring nozzle from the rear end of the vertically mounted sleeve to fill in this. This results especially in the case of comparative long or thin pods problems by taking care of it must ensure that there are no air pockets in the sleeve, i.e. it must a way to open up the air during the pouring process can flow off.
Um diesem Problem gerecht zu werden, ist es bekannt, die flüssige Minenmasse mit einer Art Injektionsnadel mit radialem Spiel zur Hülseninnenwand zu dosieren, wobei die Dosierdüse in das Innere der Hülse bis zu deren Boden eingeführt und dann mittels einer relativ komplizierten Kinematik sukzessive entsprechend dem fortschreitenden Füllstand der Hülse angehoben wird. Dementsprechend kann die Luft zwischen der Gießdüse und der Hülsenwand entweichen.To deal with this problem, it is known to use the liquid mine mass with a kind of injection needle with radial play to the inner wall of the sleeve to dose, with the dosing nozzle inside the sleeve up to introduced the bottom and then using a relatively complicated kinematics successively according to the progressive fill level of the sleeve is raised. Accordingly, the air between the pouring nozzle and escape from the sleeve wall.
Diese Arbeitsweise macht das Vorsehen relativ komplizierter mechanischer Maschinen zum präzisen Einführen der Gießdüse erforderlich, wobei sowohl in radialer Richtung eine exakte Positionierung notwendig ist als auch eine exakte Lageveränderung in vertikaler Richtung in Abhängigkeit von dem Füllzustand der Hülse.This way of working makes the provision of relatively more complicated mechanical Machines required for precise insertion of the pouring nozzle, both exact positioning in the radial direction is necessary as well an exact change in position in the vertical direction depending on the filling state of the sleeve.
Aus der DE 43 03 563 ist es schließlich bekannt, in der Hülse ein Verschlußteil anzuordnen, welches sich zu Beginn des Gießvorgangs im Bereich eines ersten Endes der Hülse befindet und mit fortschreitendem Gießvorgang entsprechend der Menge der zugeführten flüssigen Minenmasse in der Hülse bis in den Bereich des zweiten Hülsenendes bewegt wird.From DE 43 03 563 it is finally known to have a closure part in the sleeve to arrange, which is in the area at the beginning of the casting process a first end of the sleeve and with progressive casting according to the amount of liquid mine mass supplied in the sleeve is moved into the area of the second sleeve end.
Diese bekannten Verfahren weisen nach Nachteil auf, daß schwerkraftabhängig eine Minenseele entsteht, daß es zu Verschmutzungen der Gießform kommt und daß Strukturrisse, Luftblasen und Lunker aufgrund unterschiedlicher Geometrie und Volumina von Dosierkammern und Mine sowie rauher Innenoberfläche bzw. durch Kippen des Minenrohrs unmittelbar nach dem Befüllen zu beobachten sind.These known methods have the disadvantage that they are dependent on gravity A soul of mines arises that it contaminates the mold comes and that structure cracks, air bubbles and voids due to different Geometry and volumes of dosing chambers and refills as well rough inner surface or by tilting the lead pipe immediately can be observed after filling.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der eingangs genannten Art so auszugestalten, daß die aus dem Stand der Technik bekannten Nachteile vermieden werden und zudem eine vergleichsweise hohe Produktionsgeschwindigkeit erzielbar ist.Proceeding from this, the object of the invention is a method and to design a device of the type mentioned at the beginning, that the disadvantages known from the prior art are avoided and also a comparatively high production speed can be achieved is.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Hülse in der Halteeinrichtung in einem spitzen Winkel zur Horizontalen wenigstens mit ihrem unteren Ende derart gelagert ist, daß sie von dem freien, gegenüberliegenden Ende her befüllbar ist, wobei sich an die Stirnfläche des unteren Endes vorzugsweise ein Formbereich zur Ausbildung einer Spitze anschließt und wobei die beim Gießen verdrängte Luft durch eine Lüftungsbohrung austritt, welche sich im Bereich der Oberseite der unteren Stirnfläehe der Hülse nach außen wegerstreckt. Vorzugsweise liegt der Neigungswinkel zur Horizontalen bei etwa 10°.This object is achieved in that the sleeve in the Holding device at an acute angle to the horizontal at least with its lower end is mounted so that it is from the free, opposite End can be filled, with the end face of the lower In the end, preferably a molding area is connected to form a tip and wherein the air displaced during casting through a ventilation hole emerges, which is in the area of the top of the lower end face the sleeve extends outwards. The angle of inclination is preferably to the horizontal at about 10 °.
Durch die erfindungsgemäße Ausgestaltung ist es gelungen, in optimaler Weise die grundsätzlichen Vorteile des horizontalen Gießens mit einer schnellen und sauberen Produktionsmethode zu verbinden und dabei in verblüffend einfacher Weise das Problem der Luftverdrängung zu lösen.The design according to the invention has succeeded in optimal Way the basic advantages of horizontal casting with a to combine fast and clean production method while doing in surprisingly simple way to solve the problem of air displacement.
