Description
Die Erfindung betrifft ein Spritzwerkzeug zum Herstellen von Behältern aus Kunststoff mit einem Auswerfer, der die Bodenfläche des Behälters beaufschlagt. The invention relates to an injection molding tool for producing containers made of plastic with a Ejector that hits the bottom surface of the container.
Bei den üblichen Spritzwerkzeugen für KunststoS-eimer und ähnliche Gefäße sind in den Werkzeugkernen Auswerferstifte oder Auswerferteller angeordnet, die nur Teile der inneren Bodenfläche der Eimer oder Behälter beaufschlagen.With the usual injection molds for plastic buckets and similar vessels are arranged in the tool cores, ejector pins or ejector plates, which only apply to parts of the inner bottom surface of the buckets or containers.
Da die Eimer oder Behälter auf den Werkzeugkernen festschrumpfen, neigen derartige Auswerfer dazu, die Bodenfläche zu durchstoßen, anstatt die Eimer oder Behälter von den Kernen loszudrücken. Dieser Nachteil ist besonders dann störend, wenn ausSince the buckets or containers shrink onto the tool cores, such ejectors tend to be to puncture the bottom surface rather than pushing the buckets or containers away from the cores. This disadvantage is particularly annoying when out
25 Wirtschaftlichkeitsgründen möglichst kurze Zykluszeiten erreicht werden müssen und die Spritzteile möglichst heiß entformt werden. For reasons of economy, cycle times that are as short as possible must be achieved and the molded parts must be demolded as hot as possible.
Ziel und Aufgabe der vorliegenden Erfindung war es daher diese Nachteile zu vermeiden, d. h. auch bei kurzen Zykluszeiten Durchstoßungen oder durch den Auswerfer bedingte Beschädigungen der Behälteroberfläche zu vermeiden.The aim and object of the present invention was therefore to avoid these disadvantages, ie to avoid punctures or damage to the container surface caused by the ejector even with short cycle times.
Die Lösung dieser Aufgabe besteht erfindungsgemäß darin, daß der Auswerfer darüber hinaus auch einen Teil der Mantelfläche beaufschlagt und im Auswerfer ein Preßluftventil bekannter Bauart angeordnet ist.The solution to this problem is, according to the invention, that the ejector also a part of the lateral surface is applied and a compressed air valve of known design is arranged in the ejector is.
Nach der vorliegenden Erfindung wird der Auswerfvorgang aufgeteilt, denn der Behälter wird zunächst vom Kern gelöst und dann abgeblasen. Damit wird eine Beschädigung der Behälter durch Auswerfer ausgeschlossen.According to the present invention, the ejection process is divided because the container is first detached from the core and then blown off. This prevents the container from being damaged by ejectors locked out.
In der Zeichnung wird die Erfindung an Hand eines Ausführungsbeispiels näher erläutert. Mit a ist der Werkzeugkern und b der Behälter bezeichnet. Der Auswerfer c beaufschlagt die ganze/ Bodenfläche und einen Teil der Mantelfläche des Be- * hälters b. In the drawing, the invention is explained in more detail using an exemplary embodiment. With a is the tool core and b denotes the container. The ejector c acts on the entire / bottom surface and part of the outer surface of the container b.
Beim Auswerfen wird der Behälter durch den Auswerfer zunächst von dem auswerferfreien Kernmantel gelockert und von dem Auswerfer geringfügig mitgenommen. Gleichzeitig wird das im Auswerfer angeordnete Preßluftventil d geöffnet und der Behälter vom Auswerfer abgeblasen.During ejection, the ejector first loosens the container from the ejector-free core jacket and the ejector takes it along slightly. At the same time, the compressed air valve d arranged in the ejector is opened and the container is blown off from the ejector.
