Die vorliegende Erfindung betrifft eine Neuerung, um auf Formlinge, welche in Quetschpressen hergestellt und deren Formflächen mittels einer Zerstäubungsvorrichtung mit Flüssigkeiten überzogen werden, diese Flüssigkeiten als Überzug zu übertragen. Nach der deutschen Patentschrift 107611 wird zwar Glasurflüssigkeit durch Druckluft mittels einer Düse in fein verteiltem Zustande regenartig auf die zu glasierenden Gegenstände aufgetragen, indem die zu glasierenden Gegenstände auf einem endlosen Transportbande unter dem Behälter hindurchgeführt werden; es wird also die Flüssigkeit auf bereits fertig gepreßte Gegenstände aufgebracht. Diese Arbeitsweise kommt indessen bei der vorliegenden Erfindung nicht zur Anwendung. Das vorliegende Verfahren besteht nicht darin, einzelne bereits fertig gepreßte GegenständeThe present invention relates to an innovation in order to be able to produce molded articles in Compression presses produced and their molding surfaces by means of an atomizing device are coated with liquids to transfer these liquids as a coating. According to the German patent specification 107611 glaze liquid through compressed air by means of a nozzle in a finely divided state like rain applied to the objects to be glazed by placing the objects to be glazed on an endless conveyor belt passed under the container; so the liquid is already finished pressed objects applied. This way of working, however, applies to the present one Invention not applicable. The present method does not consist in individual already finished pressed objects
unmittelbar mit einer Überzugsmasse durch Bespritzen zu versehen, sondern es soll die Preßfläche bespritzt werden und diese soll die Flüssigkeit als Überzug an den erst zu formenden Gegenstand abgeben. Die Form-to be provided directly with a coating mass by spraying, but it should be the The pressing surface is to be sprayed and this is intended to apply the liquid as a coating to the first release the forming object. Form-
flächen geben die Überzugsflüssigkeit also während der Preßwirkung als Überzug an den Formling ab. Es ist zwar auch bekannt, Preßformen und Preßstempel mit Öl zu überziehen, zu dem Zweck, ein leichtes Loslösen der Preßlinge aus den Formen zu erreichen. surfaces indicate the coating liquid as a coating during the pressing action the molding off. It is also known to coat molds and rams with oil, for the purpose of achieving easy detachment of the compacts from the molds.
Der Zweck der vorliegenden Erfindung besteht aber nicht darin, die Adhäsion der Form am Preßling zu vermindern, sondern den Preßling mit einer Begußmasse zu überziehen. The purpose of the present invention is not the adhesion of the To reduce the shape of the compact, but rather to coat the compact with a casting compound.
Zu diesem Zwecke wird die Formfläche des Oberstempels in dem Augenblick, in welchem er hoch steht, mit Begußflüssigkeit mittels einer Zerstäubungsvorrichtung bespritzt. Die Flüssigkeit bleibt in dünner Schicht an dem Stempel hängen und gibt bei der darauf folgenden Pressung die Überzugsmasse an den Formling ab, so daß der Preßling nun mit einem Überzug versehen wird, welcher fest an der Oberfläche haftet.For this purpose, the form surface of the upper punch is at the moment in which he stands tall, sprayed with casting liquid by means of an atomizing device. The liquid sticks to the stamp in a thin layer and is applied to it following pressing the coating mass from the molding, so that the molding is now is provided with a coating which adheres firmly to the surface.
Auch die Formflächen auf der Trommel können in gleicher Weise mit Begußflüssigkeit bestäubt werden. Es geschieht dies am besten, wenn die Unterform wagerecht nach unten geneigt ist. Bei Schlitten und anderen Quetschpressen erfolgt das Bespritzen sachgemäß in der gleichen Weise.The mold surfaces on the drum can also be poured with pouring liquid in the same way be pollinated. This is best done when the lower mold is inclined horizontally downwards. With sledges and others Squeezing the spraying is done properly in the same way.
