Abstract

A device for supporting an upper mold tool (7) for movement with respect to a lower mold tool (25). Compared to known devices with simple pivoting supports, in which the space conditions for handling the workpieces with the mold tool opened are very restricted, the upper mold tool (7) is supported on a frame (1) by means of a multi-bar mechanism, such as a four-bar mechanism (10, 11) or a six-bar mechanism to provide a very wide opening of the space between the two mold tools.

Description

Die Erfindung betrifft eine Vorrichtung zur bewegbaren Lagerung eines oberen Formwerkzeugs gemäß dem Oberbegriff des Patentanspruchs 1 .The invention relates to a device for the movable mounting of an upper mold according to the preamble of patent claim 1.

Bei zweiteiligen Formwerkzeugen ist es beispielsweise aus der CH 305 778 A bekannt, das obere Formwerkzeug mittels eines einfachen Schwenkantriebs aus einer geschlossenen Betriebsstellung, in der das obere Formwerkzeug und das untere Formwerkzeug geschlossen sind und in ihnen ein Werkstück durch Spritzen oder Gießen hergestellt wird, in eine geöffnete Beschickungs- bzw. Entnahme oder Wartungsposition zu bewegen, in der das obere Formwerkzeug zum Einlegen von Einlegeteilen, zur Entnahme des fertigen Werkstücks und/oder zur Reinigung der Form um 180° geschwenkt und seitlich abgelegt wird. Diese weite Schwenkbewegung erfordert relativ viel Zeit und Raum.In two-part molds, it is known, for example from CH 305 778 A, the upper mold by means of a simple pivoting drive from a closed operating position in which the upper mold and the lower mold are closed and in which a workpiece is produced by injection or molding, in to move an open loading or unloading or maintenance position, in which the upper mold for inserting inserts, for removing the finished workpiece and / or for cleaning the mold pivoted by 180 ° and stored laterally. This wide pivoting movement requires a relatively large amount of time and space.

In einer anderen bekannten Ausführungsform wird das obere Formwerkzeug durch einen einfachen Schwenkantrieb in einem Abstand oberhalb des unteren Formwerkzeugs gehalten.In another known embodiment, the upper mold is held by a simple pivot drive at a distance above the lower mold.

Nachteilig an dieser Konfiguration ist, dass der Raum zwischen den Formwerkzeugen insbesondere bei großen Werkstücken nur sehr schwer zugänglich ist. Diesem Nachteil wird teilweise dadurch begegnet, dass ein zweiter Antrieb zusätzlich zur Schwenkbewegung eine horizontale Verschiebung des oberen Formwerkzeugs ermöglicht. Hierdurch erhöht sich jedoch der Aufwand und somit die Kosten einer derartigen Vorrichtung beträchtlich.A disadvantage of this configuration is that the space between the molds is very difficult to access, especially for large workpieces. This disadvantage is partially countered by the fact that a second drive in addition to the pivoting movement allows a horizontal displacement of the upper mold. However, this increases the cost and thus the cost of such a device considerably.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, die bei geringem Plathbedarf eine deutlich bessere Zugänglichkeit bei einer gleichzeitig kostengünstigen Herstellung ermöglicht.The present invention has for its object to provide a device that allows for low Plathbedarf significantly better accessibility at the same time cost-effective production.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind den Unteransprüchen entnehmbar.This object is solved by the features of patent claim 1. Advantageous embodiments are the dependent claims.

Der Kern der vorliegenden Erfindung liegt darin, dass das obere Formwerkzeug mittels eines Viergelenkgetriebes an einem Gestell schwenkbar gelagert ist, so dass die Schwenkbahn ein sehr weites Öffnen des Raumes zwischen beiden Formwerkzeugen ermöglicht.The core of the present invention is that the upper mold is pivotally mounted on a frame by means of a four-bar mechanism, so that the pivot path allows a very wide opening of the space between the two molds.

Gemäß einer vorteilhaften Ausgestaltung ist vorgesehen, dass das obere Formwerkzeug mittels einer Zugstange und eines Dreieckhebels an einem sich vertikal erstreckenden Teil des Gestells angelenkt ist. Dabei bildet ein Schenkel des Dreieckhebels in Verbindung mit der Zugstange ein Viergelenkgetriebe, wobei an einer anderen Ecke des Dreieckhebels ein Antrieb zur Erzeugung einer Schwenkbewegung angelenkt ist.According to an advantageous embodiment, it is provided that the upper mold is articulated by means of a pull rod and a triangular lever to a vertically extending part of the frame. In this case, a leg of the triangular lever in conjunction with the drawbar forms a four-bar linkage, wherein at a different corner of the triangular lever, a drive for generating a pivoting movement is articulated.

Vorteilhafterweise beträgt das Verhältnis von Lastarm zu Kraftarm am Dreieckhebel in etwa zwei zu eins. Dadurch ist mit einem geringen Betätigungsweg des Antriebes ein relativ großer Schwenkweg des oberen Formwerkzeugs erzielbar.Advantageously, the ratio of load arm to power arm on the triangle lever in about two to one. As a result, with a small actuating travel of the drive, a relatively large pivoting travel of the upper mold can be achieved.

Vorzugsweise ist auch das untere Formwerkzeug schwenkbar am Gestell gelagert. Dadurch läßt sich eine ergonomisch vorteilhafte Position für die Entnahme der Werkstücke und die Reinigung der Form erreichen.Preferably, the lower mold is pivotally mounted on the frame. As a result, an ergonomically advantageous position for the removal of the workpieces and the cleaning of the mold can be achieved.

Nachfolgend ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnung beschrieben. Die einzige Figur 1 zeigt eine Seitenansicht der erfindungsgemäßen Vorrichtung bei geöffnetem Formwerkzeug.Hereinafter, an embodiment of the invention will be described with reference to the drawing. The sole FIGURE 1 shows a side view of the device according to the invention with the mold open.

In Figur 1 ist eine Vorrichtung zur bewegbaren Lagerung eines Formwerkzeugs bei geöffnetem Formwerkzeug dargestellt. Die Vorrichtung weist ein Gestell 1 auf, das sich aus einem plattenförmigen Maschinenfundament, einem Paar von vertikal daran befestigten Wangen 2 und gegenüberliegend zu den Wangen 2 angeordneten vertikalen Stützen 3 zusammensetzt.FIG. 1 shows a device for the movable mounting of a mold with the mold open. The device comprises a frame 1, which is composed of a plate-shaped machine foundation, a pair of cheeks 2 attached vertically thereto, and vertical supports 3 arranged opposite the cheeks 2.

An den Wangen 2 ist mittels eines Lagers 15 ein Dreieckhebel 11 schwenkbar gelagert. Dieser Dreieckhebel 11 ist an seiner linken oberen Ecke im Bereich einer Anlenkung 16 mit dem oberen Ende einer Kolbenstange 17 verbunden, die zu einem Hydraulikzylinder 18 gehört, dessen unteres Ende nahe dem plattenförmigen unteren Teil des Gestells 1 im Bereich einer Anlenkung 19 mit der Wange 2 gelenkig verbunden ist.On the cheeks 2, a triangular lever 11 is pivotally mounted by means of a bearing 15. This triangular lever 11 is connected at its upper left corner in the region of an articulation 16 with the upper end of a piston rod 17 which belongs to a hydraulic cylinder 18, the lower end near the plate-shaped lower part of the frame 1 in the region of articulation 19 with the cheek second articulated is connected.

An den Wangen 2 ist ferner im Bereich eines Gelenks 13 eine Zugstange 10 angelenkt, deren anderes Ende im Bereich eines Gelenks 12 an einer Anlenkplatte 9 des oberen Formwerkzeugs befestigt ist. An dieser Anlenkplatte 9 ist auch das rechte äußere Ende des Dreieckhebels 11 im Bereich eines Gelenks 14 befestigt. Der sich zwischen dem Lager 15 und der Anlenkung 14 erstreckenden Schenkel (= Lastarm B) bildet gemeinsam mit der Zugstange 10 ein Viergelenkgetriebe. Dieses wird angetrieben von einem Antrieb in Form des Hydraulikzylinders 18. Der Abstand der Anlenkung 16 der Kolbenstange 17 zum Lager 15 bildet den Kraftarm A am Dreieckhebel 11. Das Verhältnis von Kraftarm A zu Lastarm B beträgt vorzugsweise etwa eins zu zwei, so daß mittels eines relativ kurzen Betätigungsweges des Hydraulikzylinders 18 eine relativ große Schwenkbewegung des oberen Formwerkzeugs erzielbar ist.On the cheeks 2, a tie rod 10 is further articulated in the region of a joint 13, the other end is fixed in the region of a joint 12 to a hinge plate 9 of the upper mold. At this articulation plate 9 and the right outer end of the triangular lever 11 in the region of a joint 14 is attached. The extending between the bearing 15 and the linkage 14 legs (= load arm B) forms a four-bar linkage together with the drawbar 10. This is driven by a drive in the form of the hydraulic cylinder 18. The distance of the articulation 16 of the piston rod 17 to the bearing 15 forms the power arm A on the triangle lever 11. The ratio of the power arm A to Lastarm B is preferably about one to two, so that by means of a relatively short actuation travel of the hydraulic cylinder 18, a relatively large pivotal movement of the upper mold is achievable.

Das obere Formwerkzeug 7 ist mittels einer oberen Aufspannplatte 6 an einem oberen Formträger 5 befestigt, der seinerseits an der Anlenkplatte 9 angeflanscht ist. Am oberen Formträger 5 ist ein als Hydraulikzylinder ausgebildeter Hubzylinder 29 angeordnet, dessen Kolben mit seinem unteren Ende an der Aufspannplatte 6 befestigt ist. Mittels dieses Hubzylinders 29 ist die Aufspannplatte 6 mit dem oberen Formwerkzeug 7 entlang von Führungen 28 relativ zum oberen Formträger 5 linear verfahrbar.The upper mold 7 is fixed by means of an upper platen 6 to an upper mold carrier 5, which in turn is flanged to the hinge plate 9. At the upper mold carrier 5 designed as a hydraulic cylinder lifting cylinder 29 is arranged, the piston is fixed with its lower end to the platen 6. By means of this lifting cylinder 29, the platen 6 with the upper mold 7 along guides 28 relative to the upper mold carrier 5 is linearly movable.

Am oberen Formträger 5 ist eine Verriegelung 4 in Form eines senkrecht zur Zeichenebene verfahrbaren Bolzens vorgesehen, die bei herabgeschwenktem oberen Formträger 5 mit einer Verriegelungsbohrung 8 am oberen Ende der Stützen 3 in Eingriff bringbar ist.At the upper mold carrier 5, a lock 4 is provided in the form of a perpendicular to the plane movable bolt, which is brought down in swung-upper mold carrier 5 with a locking bore 8 at the upper end of the supports 3.

Zum gesamten Werkzeug gehört auch ein unteres Formwerkzeug 25, das an einer unteren Aufspannplatte 20 befestigt ist, welche ihrerseits mittels eines Lagers 23 schwenkbar am Gestell 1 befestigt ist. Die untere Aufspannplatte 20 ist mittels eines Hydraulikzylinders 21, dessen unteres Ende mittels einer Anlenkung 24 am Gestell 1, und dessen oberes Ende mit seiner ausfahrbaren Kolbenstange im Bereich einer Anlenkung 22 an der unteren Aufspannplatte 20 befestigt ist, aus der in der Figur 1 gezeigten Beschickungs- bzw. Entnahme- und /oder Wartungsposition in eine Betriebsposition schwenkbar, in der das untere Formwerkzeug 25 parallel zur unteren Platte des Gestells 1 liegt.The entire tool also includes a lower mold 25 which is fixed to a lower platen 20, which in turn is pivotally mounted on the frame 1 by means of a bearing 23. The lower platen 20 is fixed by means of a hydraulic cylinder 21, the lower end by means of a linkage 24 on the frame 1, and the upper end with its extendable piston rod in the region of an articulation 22 on the lower platen 20, from the feed shown in the figure 1 - Or removal and / or maintenance position in an operating position pivotally, in which the lower mold 25 is parallel to the lower plate of the frame 1.

Am unteren Formwerkzeug 25 ist bei Bedarf eine Schiebersteuerung 26 angeordnet, mittels der gegebenenfalls Schieber zur Erzeugung von Hinterschnitten am Werkstück betätigbar sind. Auswerfer 27 erleichtern das Ausheben des fertigen Werkstücks aus dem unteren Formwerkzeug 25.If necessary, a slider control 26 is arranged on the lower molding tool 25, by means of which, if appropriate, slides for producing undercuts on the workpiece can be actuated. Ejectors 27 facilitate the removal of the finished workpiece from the lower mold 25th

Mittels der durch das Viergelenkgetriebe 10 bzw. 11 erzeugten weiten Schwenkbewegung wird das Formwerkzeug in der in Figur 1 gezeigten Beschickungs- bzw. Entnahme- und/oder Wartungsposition soweit geöffnet, daß das Bedienpersonal einen ungehinderten Zugriff hat. Ebenso kann mittels eines Roboters das Einlegen von Einlegeteilen und die Entnahme des fertigen Werkstücks ungehindert erfolgen. Die Schwenkbewegung des unteren Formwerkzeugs 25 erleichtert den Zugang zusätzlich.By means of the wide pivoting movement generated by the four-bar linkage 10 and 11, the mold is opened in the feed or removal and / or maintenance position shown in Figure 1 so far that the operator has unimpeded access. Likewise, the insertion of inserts and the removal of the finished workpiece can be carried out unhindered by means of a robot. The pivotal movement of the lower mold 25 also facilitates access.

In der Arbeitsposition ist der Hydraulikzylinder 21 eingefahren und das untere Formwerkzeug 25 nimmt eine horizontale Lage ein. Das obere Formwerkzeug 7 wird mittels des Viergelenkgetriebes durch den Hydraulikzylinder 18 nach unten geschwenkt und die Verriegelung 4 mit der Verriegelungsbohrung 8 in Eingriff gebracht. Daraufhin wird mittels des Hubzylinders 29 das obere Formwerkzeug 7 auf das untere Formwerkzeug 25 abgesenkt und an dieses fest angedrückt. Mittels nicht gezeigter Einspritzvorrichtungen wird nunmehr flüssiger Kunststoff in die Formen hineingedrückt und dadurch das Werkstück erzeugt. Anschließend wird das obere Formwerkzeug 7 mittels des Hubzylinders 29 angehoben, die Verriegelung 4 gelöst und der obere Formträger 5 mittels des Viergelenkgetriebes 10 bzw. 11 nach oben geschwenkt. Optional wird das untere Formwerkzeug 25 in die in der Figur 1 gezeigte Schräglage gekippt und nach Betätigung der Schiebersteuerung 26 und der Auswerfer 27 kann das fertige Werkstück entnommen, die Form bei Bedarf gereinigt werden und gegebenenfalls Einlegeteile zur Herstellung des nächsten Werkstücks eingelegt werden.In the working position of the hydraulic cylinder 21 is retracted and the lower mold 25 assumes a horizontal position. The upper mold 7 is pivoted by means of the four-bar mechanism by the hydraulic cylinder 18 down and the lock 4 is brought into engagement with the locking hole 8. Then, by means of the lifting cylinder 29, the upper mold 7 is lowered onto the lower mold 25 and pressed firmly to this. By means of injectors, not shown now liquid plastic is pressed into the molds and thereby generates the workpiece. Subsequently, the upper mold 7 is raised by means of the lifting cylinder 29, the lock 4 is released and the upper mold carrier 5 is pivoted by means of the four-bar mechanism 10 and 11 upwards. Optionally, that will lower mold 25 tilted into the inclined position shown in Figure 1 and after actuation of the slide control 26 and the ejector 27, the finished workpiece can be removed, the mold can be cleaned if necessary and optionally inserts are inserted for the production of the next workpiece.

Anstelle des beschriebenen Viergelenkgetriebes 10 bzw. 11 kann auch ein anderes Mehrgelenkgetriebes, wie beispielsweise ein Sechsgelenkgetriebe ebenso vorteilhaft zur Erzeugung einer Schwenkbewegung des oberen Formwerkzeugs verwendet werden.Instead of the described four-bar mechanism 10 and 11, another multi-link transmission, such as a six-bar linkage can also be used advantageously for generating a pivoting movement of the upper mold.
