PATENTAMT.PATENT OFFICE.
Gegenstand des Hauptpatents ist eine Formmaschine mit fahrbarem Pressenquerhaupt mit auf einem Untergestell eng nebeneinander liegenden Formkasten, unter denen sich Abliebevorrichtungen befinden, welche entweder hydraulisch oder von Hand betrieben werden können. Die Anbringung von Abhebevorrichtungen unter jedem Formkasten ist aber erforderlich, da die Abhebevorrichtung nicht fahrbar ist.The subject of the main patent is a molding machine with a mobile press crosshead on an underframe closely side-by-side molding boxes, under which there are waste devices which can be operated either hydraulically or by hand. The attachment of lifting devices But it is necessary under each molding box because the lifting device cannot be moved.
Um aber mit ein und derselben Abhebevorrichtung Kasten an verschiedenen Formoder Preßstellen abheben zu können, sind nach der Erfindung auch eine oder mehrere Abhebevorrichtungen fahrbar gemacht, z. B. dadurch, daß das fahrbare Pressenquerhaupt mit einer oder mehreren Abhebevorrichtungen ausgerüstet ist. Das hat den wesentlichen Vorteil, daß mehrere Betriebsstellungen mit derselben Abhebevorrichtung eingenommen werden können.However, in order to use one and the same lifting device for boxes of different shapes or To be able to lift press points, one or more lifting devices are also according to the invention made mobile, e.g. B. in that the mobile press crosshead is equipped with one or more lifting devices is. This has the major advantage that several operating positions with the same Lifting device can be taken.
Auf der Zeichnung ist schematisch eine Ausführungsform beispielsweise dargestellt, und zwar zeigt:An embodiment is shown schematically in the drawing for example, shows:
Fig. ι eine Ansicht der Maschine, und
Fig. 2 den Querschnitt.Fig. Ι a view of the machine, and
Fig. 2 shows the cross section.
Das fahrbare Pressenquerhaupt d ist mit Abhebevorrichtungen i versehen. Unter jedem Formkasten an der Formbank befinden sich Abhebesäulen k, wobei die Abhebeplatte I lose angeordnet ist. Die Abhebesäulen können aber auch fest mit der Abhebevorrichtung verbunden werden. In diesem Falle sind nicht für jeden Kasten Abhebesäulen notwendig, weil sie auch mit der übrigen Abhebevorrichtung von einem zum anderen Formkasten oder von einer in die andere Betriebsstellung fahren. Die beiden Möglichkeiten der Anbringung der Abhebesäulen bilden nicht den Gegenstand der Erfindung.The mobile press crosshead d is provided with lifting devices i. Lifting columns k are located under each molding box on the molding bench, the lifting plate I being loosely arranged. The lifting columns can also be firmly connected to the lifting device. In this case, lifting columns are not necessary for every box because they also move with the rest of the lifting device from one molding box to the other or from one to the other operating position. The two ways of attaching the lifting columns do not form the subject of the invention.
