Description
24an hat schon mit den üblichen Formmaschinen Oberkasten und Unterkasten gleichzeitig tiergestellt, um an Arbeit und Zeit für das Füllen, Pressen und Abheben zu sparen. Diese Arbeitsweise hat sich in der Praxis nicht bewährt, weil es bei ihr unvermeidlich ist, daß Sand zwischen die im Abstand voneinander befindlichen Einzelformen auf die N odellplatte fällt und weil bei Ausschuß des einen Kastenteiles aus arbeitstechnischen Gründen auch der andere Kastenteil als unbrauchbar betrachtet werden muß.24an already has an upper box and lower box with the usual molding machines at the same time, to get work and time for filling, pressing and taking off to save. This way of working has not proven itself in practice because it is its inevitable is that sand between the spaced apart Individual forms on the N odellplatte falls and because of the scrap of one part of the box for technical reasons, the other part of the box is also considered unusable must become.
Diese Nachteile treten bei der Erfindung nicht auf, die ein Verfahren zum Herstellen von kastenlosen Formen auf Formmaschinen betrifft und darin besteht, daß unter Verwendung eines mit Trennwand versehenen Formkastens und zweier Abtragroste in einem Arbeitsgang zwei vollständige kastenlose Formen hergestellt und einzeln weiterbehandelt werden. Durch die im Ober- und Unterkasten übereinstimmende Trennwand wird der entstehende Sandballen in zwei Teile, die.in der Regel gleich groß sind, zerlegt. Die auf diese Weise in einem :Arbeitsgang entstehendenFormen sind sobemessen, (laß sie mit Hilfe der gesonderten Abtragroste von einem Manne abgehoben werden können. Es entfällt also gegenüber der üblichen Herstellung eines doppelt so großen Kastens die Hilfskraft zum Abtragen, die sonst arbeitsmäßig nicht voll ausgenutzt werden kann.These disadvantages do not occur with the invention, which has a method for the production of box-less molds on molding machines and consists in that using a molding box provided with a partition and two removal grates two complete boxless molds produced and individually in one operation be treated further. Due to the matching partition wall in the upper and lower box the resulting sand ball is divided into two parts, which are usually the same size, disassembled. The shapes created in this way in one: (Have a man lift them up with the help of the separate grating can. It is therefore not necessary compared to the usual production of one that is twice as large Box the auxiliary worker for the removal, who is otherwise not fully utilized in terms of work can be.
Es ist zweckmäßig, die Trennwand in den Kästen fest anzuordnen, doch besteht auch die Möglichkeit, die Trennwand herausnehmbar anzubringen.It is advisable to fix the partition in the boxes, however there is also the option of attaching the partition so that it can be removed.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, und zwar zeigen die Abbildungen in Stirnansicht und in einem senkrechten Mittelschnitt einen Oberkasten i (Abb. i und 2) und einen Unterkasten 2 (.'1bb. 3 und :I), je mit einer Trennwand 3 bzw. 4, die in ihrer Lage miteinander übereinstimmen.In the drawing, an embodiment of the invention is shown, namely show the figures in front view and in a vertical center section an upper box i (Fig. i and 2) and a lower box 2 (.'1bb. 3 and: I), each with a partition 3 or 4, which coincide with one another in their position.
