Description

Bei den bekannten Druckgießmaschinen mit für sich angetriebener Auswerfervorrichtung ist der Träger der Auswerfersammelpiatte in Richtung der Formenschließbewegung verschiebbar, im übrigen aber ortsfest gelagert, und zwar koaxial zum Einguß. In the known die casting machines with a driven ejector device the carrier of the ejector collection plate can be moved in the direction of the mold closing movement, but otherwise stored in a stationary manner, coaxially with the sprue.

Wenn bei solchen Maschinen Auswerferstifte nur auf einer Seite des Eingusses angeordnet sind, was bei Gußstücken mit indirektem außenliegendemEinguß stets,, aber auch bei anderen Stücken häufig der Fall ist, so muß mit Rücksicht auf die Befestigungsmöglichkeit im Antriebsglied trotzdem eine Auswerfersammelplatte angeordnet werden, die wenigstens bis zur Eingußachse reicht. Außerdem muß für die Sammelplatte eine besondere Führung vorgesehen werden, wenn vermieden werden soll, daß die Auswerferstifte infolge unzentrischen Antriebes verkanten. Diese Maßnahme hat zur Folge, daß die Bauweise der Maschine unübersichtlich wird, und daß es schwierig wird, etwa vorzusehende Kerne günstig unterzubringen. If on such machines ejector pins are only on one side of the Sprue are arranged, which is the case with castings with indirect external sprue is always, but also often the case with other pieces, it must be done with consideration an ejector collecting plate to the possibility of fastening in the drive member be arranged, which extends at least to the sprue axis. Also must for the Collecting plate a special guide should be provided if it is to be avoided that the ejector pins tilt due to the eccentric drive. This measure has the consequence that the construction of the machine is confusing, and that it is difficult is to accommodate any cores to be provided inexpensively.

Gemäß der Erfindung werden diese Schwierigkeiten dadurch behoben, daß der Antrieb der für die Auswerfersammelplatte an einer an der beweglichen Formträgerplatte drehbar gelagerten Scheibe in radialer Richtung verschiebbar ist. According to the invention, these difficulties are overcome by that the drive for the ejector collecting plate on one of the movable mold carrier plate rotatably mounted disc is displaceable in the radial direction.

Bei dieser Anordnung ist es nicht notwendig, die Auswerfersammelplatte größer zu machen, als dem Abstand der am weitesten voneinander entfernten Auswerferstifte entspricht, und es erübrigt sich auch eine besondere Führung dafür, weil sich das sie tragende Befestigungsglied ohne weiteres zentral zu den Stiften anordnen läßt. With this arrangement, it is not necessary to use the ejector collection plate larger than the distance between the most distant ejector pins corresponds, and there is also no need for special guidance because that they can easily arrange the supporting fastening member centrally to the pins.

In der Zeichnung ist ein Ausführungsbeispiel einer gemäß der Erfindung ausgebildetenAuswerfervorrichtung schematisch dargestellt, und zwar zeigt Fig. I einen Längsschnitt durch die Vorrichtung, während Fig. 2 einen Querschnitt nach der Linie A-A in Fig. 1 darstellt. In the drawing is an embodiment of one according to the invention formed ejector device is shown schematically, namely Fig a longitudinal section through the device, while Fig. 2 shows a cross section the line A-A in fig.

Bei dem gezeichneten Ausführungsbeispiel sind Auswerferstifte 1 nur rechts von dem in der Gießform vorgesehenen Einguß 2 angeordnet. Die Stifte sind in bekannter Weise in einer Auswerfersammelplatte 3 befestigt. Zum Antrieb der Sammelplatte 3 dient ein Hydraulikzylinder4, der an einer an der beweglichen Formträgerplatte 5 drehbar gelagerten Scheibe 6, die einen. radialen Schlitz 7 aufweist, durch Festklemmen mittels einer Mutter 8 befestigt ist. Durch Verschieben des Zylinders 4 längs des Schlitzes 7 und durch Drehen der Scheibe 6, an deren Stelle natürlich auch nur ein Scheibenausschnitt angeordnet sein kann, läßt sich der Träger g der Sammelplatte 3 in jede gewünschte Lage bringen. In the illustrated embodiment, ejector pins 1 are only arranged to the right of the sprue 2 provided in the casting mold. The pens are attached in a known manner in an ejector collecting plate 3. For driving the collecting plate 3, a hydraulic cylinder 4 is used, which is attached to one of the movable mold carrier plate 5 rotatably mounted disc 6, the one. having radial slot 7 by clamping is fastened by means of a nut 8. By moving the cylinder 4 along the Slot 7 and by turning the disc 6, in its place of course only one Disc cutout can be arranged, the carrier g of the collecting plate Bring 3 into any desired position.
