Abstract
Description
Die Erfindung betrifft ein Spritzwerkzeug zum Herstellen von Bauteilen aus Kunststoff -- insbesondere von Kunststofftasten für Tastaturfelder -- auf dem Wege des Spritzens.The The invention relates to an injection molding tool for producing components plastic - in particular plastic keys for keypads - by the way of splashing.
Der Erfinder hat sich die Aufgabe gestellt, den Formvorgang insbesondere für Kunststofftastaturen sowie das dafür erforderliche Formwerkzeug zu verbessern.Of the The inventor has set himself the task of the molding process in particular for plastic keyboards as well as that necessary mold to improve.
Zur Lösung dieser Aufgabe führt die Lehre des unabhängigen Anspruches; die Unteransprüche geben günstige Weiterbildungen an. Zudem fallen in den Rahmen der Erfindung alle Kombinationen aus zumindest zwei der in der Beschreibung, der Zeichnung und/oder den Ansprüchen offenbarten Merkmale. Bei angegebenen Benennungsbereichen sollen auch innerhalb der genannten Grenzen liegende Werte als Grenzwerte offenbart und beliebig einsetzbar sein.to solution performs this task the teaching of the independent claim; to give the dependent claims favorable Further education. In addition, all fall within the scope of the invention Combinations of at least two in the description, the drawing and / or the claims disclosed features. For specified naming ranges should also Values within limits are disclosed as limits and be used as desired.
Erfindungsgemäß ist eine Abhebeeinheit mit Formplatte vorhanden, mit welcher durch jeweils zumindest zwei Stabsäulen zwei Querbalken verbunden sind; letztere sollen durch zwei Längsbalken zu einem Gehäuserahmen ergänzt sein, der seinerseits an den Stabsäulen verfahrbar ist.According to the invention is a Lifting unit with mold plate available, with which by each at least two staff columns two transverse bars are connected; the latter should be by two longitudinal beams to a case frame added be, which in turn is movable on the staff columns.
Nach einem weiteren Merkmal der Erfindung ist dem Gehäuserahmen parallel zu der mit letzterem verbundenen Formplatte eine weitere Formplatte zugeordnet; die erstgenannte Formplatte trägt links- und rechtsseitig Formschieber für unterschiedliche Spritzvorgänge.To Another feature of the invention is the housing frame parallel to the the latter associated mold plate associated with a further mold plate; carries the former form plate Left and right side mold slide for different spraying processes.
Auch hat es sich als günstig erwiesen, die beiden jochartigen Querbalken in ihrem Zentrum jeweils mit einem Lagerbereich für eine Dreheinheit mit Drehkörper zu versehen; an dessen Außenflächen ragen Transportzapfen ab.Also it has to be cheap proved, the two yoke-like crossbeams in their center respectively with a storage area for a turntable with rotating body to provide; protrude on its outer surfaces Transport pin off.
Erfindungsgemäß ist ein Kühlblech an jedem Transportzapfen vorgesehen, das in den Drehkörper eingreift, dies bevorzugt im Bereich eines O-Ringes.According to the invention is a heatsink provided on each transport pin, which engages in the rotary body, this is preferred in the range of an O-ring.
Als günstig hat es sich erwiesen, der Drehleiste einen diese um ihre Längsachse drehenden Getriebemotor zuzuordnen. Zwischen dem Getriebemotor und einem an einem Axialzapfen angeordneten gezahnten Firstrad sollen über der Drehleiste Zahnräder vorgesehen sein. Zudem durchgreift der Axialzapfen eine Halteschale und ist in einer firstwärtigen Antriebswelle der Drehleiste angeordnet. Oberhalb letzterer soll ein die Antriebswelle umfangendes Lager vorgesehen sein, am anderen Ende der Drehleiste ein weiteres Lager und oberhalb dessen bevorzugt eine Kühlspirale.When Cheap it has been proven, the rotary bar this one about its longitudinal axis assigned to rotating geared motor. Between the geared motor and a arranged on an axial pin toothed ridge wheel are about the Turnstile gears be provided. In addition, the axial pin passes through a holding shell and is in a first line Drive shaft of the rotary bar arranged. Above the latter should a drive shaft circumferential bearing be provided on the other End of the pivot bar another camp and above preferred a cooling spiral.
Nach einem weiteren Merkmal der Erfindung ist eine Zwischenplatte einer Auswerfergrundplatte zugeordnet, an die sich die Formplatte anschmiegt.To Another feature of the invention is an intermediate plate of a Assigned ejector base plate, which conforms to the mold plate.
Mit diesem Werkzeug wird der Teiletransport nicht durch eine Drehung um die waagerechte Achse des Werkzeuges realisiert, sondern durch die Drehung um eine senkrechte Achse. Nach dem Einspritzen der ersten Spritzung wird eine Drehleiste, in der die Teile transportiert werden, in einem Rahmen nach vorn gefahren. Die Leiste wird durch den Getriebemotor, welcher auf den Rahmen montiert ist, um 90° gedreht. Danach fährt der Rahmen wieder in Ausgangslage, und das Werkzeug wird geschlossen. Nun wird parallel zur ersten Spritzung die zweite Spritzung eingespritzt. Das Werkzeug fährt auf, der Rahmen fährt nach vorne und dreht wieder um 90°. Nach dem Schließen des Werkzeuges werden nun die erste, zweite und dritte Spritzung parallel gespritzt. Nach dem Auffahren und einem Drehen der Leiste um 90° ist das erste Teil in der Abstreiferposition. Beim Zurückfahren des Rahmens taucht das Teil zwischen einem Schieberpaar durch, welches sich danach schließt. Dieses Schieberpaar bleibt so lang geschlossen, bis der Rahmen nach erneuter Einspritzung der drei Werkstoffe wieder nach vorne gefahren ist. Somit sind die Teile vom Transportzapfen abgestreift und fallen in einen Auffangbehälter.With This tool is not the part transport by a rotation realized by the horizontal axis of the tool, but by the rotation about a vertical axis. After injecting the first Spraying becomes a turning bar in which the parts are transported moved forward in a frame. The strip is driven by the gear motor, which is mounted on the frame, rotated by 90 °. Then he drives Frame back to baseline, and the tool is closed. Now the second injection is injected parallel to the first injection. The tool moves on, the frame is driving forward and turn again by 90 °. To the closing the tool will now be the first, second and third injection injected in parallel. After driving on and turning the bar around 90 ° the first part in the wiper position. When driving back the frame dives through the part between a pair of slides, which closes after that. This slide pair remains closed until the frame moves to re-injection of the three materials has driven forward again. Thus, the parts are stripped from the transport pin and fall in a collection container.
