Description
Schließmechanismus für Kunststoffmaschinen, insbesondere Großblasmaschinen zur Herstellung von Hohlkbrpern aus thermoplastischem Kunststoff.Closing mechanism for plastic machines, in particular large blow molding machines for the production of hollow bodies made of thermoplastic material.
Die Erfindung betrifft einen Schließmechanismus für Kunststoffmaschinen wie Spritzguß- und Blasmaschinen, insbesondere Großblasmaschinen zur Herstellung von Hohlkörpern aus thermoplastischem Kunststoff mit zwei relativ zueinander beweglichen Formaufspannplatten, die von die Kraft einer Zuhaltevorrichtung zum Geschlossenhalten der Form unter Zugspannung aufnehmenden Zugankern durchgriffen sind.The invention relates to a locking mechanism for plastic machines such as injection molding and blow molding machines, in particular large blow molding machines for production of hollow bodies made of thermoplastic with two relatively movable Mold mounting plates that hold closed by the force of a locking device the shape under tensile stress absorbing tie rods are penetrated.
Normalerweise dienen die Zuganker nicht nur zur Aufnahme der Schließkräfte in einem geschlossenen System, sondern auch zur Führung mindestens einer beweglichen Formauf spannplatte. Kräftemäßig ist dieses System bedeutend vorteilhafter als wenn die Schließ- und Zuhaltekräfte von einem U-förmigen Rahmen aufgenommen werden müssen, weil hier im Gegensatz zum Zugankersystem Biegekräfte auftreten, die von dem U-förmigen Rahmen aufzunehmen sind. Andererseits aber gewährleistet die Bauweise mit U-förmigen Rahmen eine gute Zugänglich keit der Form, was insbesondere bei Großmaschinen von Vorteil ist, wenn schwere Formhälften mit dem Kran gewechselt werden müssen. Auch ist das spritzgepreßte oder geblasene Kunststoffteil leicht zu entfernen.Normally, the tie rods are not only used to absorb the closing forces in a closed system, but also to guide at least one movable Mold on clamping plate. In terms of strength, this system is significantly more advantageous than if the closing and locking forces must be absorbed by a U-shaped frame, because, in contrast to the tie rod system, bending forces occur here which are caused by the U-shaped Frame are to be included. On the other hand, however, guarantees the U-shaped construction Frame a good accessibility of the form, which is especially important for large machines from The advantage is when heavy mold halves have to be changed with the crane. Even the injection-molded or blown plastic part is easy to remove.
Der Erfindungliegt die Aufgabe zugrunde, einen Schließ#echanlsmus für Kunststoffmaschinen der bezeichneten Art zu scha£-fen, der die Vorzüge beider Systeme, nämlich die Kräfteaufnahme in einem geschlossenen System einerseits und die gute Zugänglichkeit der Form andererseits in sich vereinigt. Ausgehend von einem Schließmechanismus mit die Schließ- und Zuhaltekraft aufnehmenden Zugankern besteht die Erfindung darin, daß die Formaufspannplatten auf Laufschienen ruhend unabhängig von den Zugankern geführt und die in der ersten Formaufspannplatte axial beweglich geführten Zuganker aus einer beide Formaufspannplatten in Schließlage vorübergehend verriegelnden und die Schließkraft aufnehmenden Wirklage bis zur freien Zugänglichkeit des Zwischenraums zwischen den auseinandergefahrenen Aufspannplatten zurücksteuerbar sind. Der Grundgedanke der Erfindung ist der, die Zuganker von ihrer Führungsaufgabe freizumachen, um sie - nachdem sie bei dem Herstellprozeß zusammen mit den Formaufspannplatten und der Zuhaltevorrichtung ein an sich geschlossenes Kräftesystem gebildet haben - beim Offnen der Form in eine Lage verschieben zu können, in der sie sich im Zwischenraum zwischen den auseinandergefahrenen Formaufspannplatten beim Entfernen des Kunststoffteils wie auch beim Auseechseln der Form nicht mehr störend bemerkbar machen.The invention is based on the object of providing a locking mechanism for plastic machines of the kind indicated, which has the advantages of both Systems, namely the absorption of forces in a closed system on the one hand and the good accessibility of the form on the other hand. Starting from one Closing mechanism with the closing and Holding force absorbing Tie rods, the invention consists in that the mold mounting plates on rails out dormant independently of the tie rods and in the first platen axially movably guided tie rods from one of the two mold mounting plates in the closed position temporarily locking and the closing force absorbing effective action up to the free Accessibility of the space between the spreading clamping plates are reversible. The basic idea of the invention is that the tie rods of their Leaving management responsibility free to them - after they have worked together in the manufacturing process with the mold mounting plates and the locking device a closed one Have formed a system of forces - to be able to move into a position when the mold is opened in which they are in the space between the spreading mold mounting plates when removing the plastic part as well as when changing the mold make disturbing noticeable.
Zum vorübergehenden Verriegeln der beiden in Schließlage befindlichen Formaufspannplatten über die Zuganker, von denen mindestens zwei vorhanden sein müssen, werden die Riegelenden der Zuganker gemäß der weiteren Erfindung mit einer Eindrehung versehen, in die an der zweiten Formaufspannplatte angeordnete halbschalenförmige Querriegel einlegbar sind.For temporary locking of the two in the closed position Form mounting plates over the tie rods, of which at least two are available must, the bolt ends of the tie rod according to the further invention with a Provided recess in the half-shell-shaped arranged on the second platen Cross bars can be inserted.
