Description

Im Druckgießverfahren hergestellte Werkstücke müssen nach dem Guß von dem ihnen insbesondere längs der Trennfuge der Formhälften anhaftenden Grat sowie von den Eingußzapfen und etwaigen sonstigen außerhalb des eigentlichen Gußstückes vorgesehenen Ansätzen befreit werden. Dies geschieht in der Regel mit Hilfe besonderer Abgratvorrichtungen, deren Aufbau dem der bekannten Stanzpressen gleicht und die bisher stets für sich, möglichst in besonderen Räumen, aufgestellt wurden.Workpieces manufactured using the die-casting process must after the casting of the burr adhering to them, in particular along the parting line between the mold halves as well as from the sprue and any other outside of the actual casting provided approaches are exempted. This is usually done with the help of special Trimming devices, the structure of which is similar to that of the known stamping presses and which up to now have always been set up individually, if possible in special rooms.

Gemäß der Erfindung wird demgegenüber der bewegliche Formträger einer Druckgießmaschine mit dem Stempel einer Abgratvorrichtung verbunden und beiden Stempeln ein gemeinsamer Antrieb zugeordnet. Vorzugsweise wird der Stempel der Abgratvorrichtung am Träger der beweglichen Formhälfte der Druckgießmaschine befestigt.According to the invention, in contrast, the movable mold carrier is a Die casting machine connected to the punch of a trimming device and both punches assigned to a common drive. The punch is preferably the trimming device attached to the support of the movable mold half of the die casting machine.

Durch die erfindungsgemäße Anordnung wird eine ganze Reihe von Vorteilen erzielt. Insbesondere wird das Arbeitsvermögen der Antriebsvorrichtung der Formhälften, das mit Rücksicht auf den während des Gießvorganges erforderlichen hohen Schließdruck viel größer vorgesehen werden muß, als zur Bewegung der Auswerfformhälfte notwendig wäre, besser ausgenutzt und die .Anordnung eines besonderen Antriebsmittels für die Abgratvorrichtung erspart. Ferner wird dadurch, daß die Werkstücke gleich am Ort ihrer Herstellung von sperrigen Graten, Eingüssen usw. befreit werden, deren Abtransport wesentlich vereinfacht, und es werden außerdem Beschädigungen der Werkstücke vermieden, die durch die anhängenden Grate usw. sonst häufig verursacht werden. Da das Einlegen der aus der Gießmaschine entnommenen Werkstücke in die Abgratvorrichtung ohne weitere Mühe vom Gießer übernommen werden kann, läßt sich außerdem eine erhebliche Ersparnis an Bedienungspersonal erreichen.The arrangement according to the invention has a number of advantages achieved. In particular, the working capacity of the drive device of the mold halves, this with regard to the high closing pressure required during the casting process must be provided much larger than necessary to move the ejector half would be better used and the arrangement of a special drive means for the trimming device saves. Furthermore, the fact that the workpieces are the same on The place of their manufacture should be freed of bulky burrs, castings, etc., their Removal significantly simplified, and there is also damage to the workpieces avoided, which are otherwise often caused by the attached burrs etc. Because the workpieces removed from the casting machine are placed in the trimming device can be taken over by the caster without further effort, can also be a significant Achieve savings in operating personnel.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schematisch dargestellt. An eine Druckgießmaschine, bestehend aus dem Ofen i, dem Formenträgerrahmen 2, der Deckform 3 und der am beweglichen Formträger .4 befestigten Auswerfform _#, ist eine Abgratvorrichtung, bestehend aus einem Gesenk 6 und einem Stempel 7, derart angeschlossen, daß der Stempel 7 am beweglichen Formträger 4 befestigt ist. Der Schaft 8 des Stempels ist so bemessen, daß der Stempel kurz vor der Schließung der Formhälften 3, 5 in das Gesenk 6 eintaucht und dabei den Grat abschert, der dem ins Gesenk eingelegten Werkstück 9 anhaftet. Bei der dargestellten Ausführungsform ist die Anordnung so getroffen, daß außer dem Grat auch gleich der Eingußzapfen io mit abgeschert wird.The drawing shows an embodiment of the subject matter of the invention shown schematically. To a die-casting machine, consisting of the furnace i, the Mold carrier frame 2, the cover mold 3 and attached to the movable mold carrier .4 Ejection form _ #, is a trimming device, consisting of a die 6 and a Stamp 7 connected in such a way that the stamp 7 is attached to the movable mold carrier 4 is. The shaft 8 of the stamp is dimensioned so that the stamp is about to close the mold halves 3, 5 dips into the die 6 and shears off the ridge that adhering to the workpiece 9 placed in the die. In the illustrated embodiment the arrangement is made so that, in addition to the burr, the sprue is also the same io is sheared off with.
