Abstract

A hydraulic injection machine, esp. for expanded thermoplastics, with a movable mould plate which moves clear of the guide bars on the opening stroke, has this movable plate pivotally mounted on a sliding carriage, so that when the mould has opened, the mould plate can pivot about a vertical axis through 90 degrees to discharge the moulding.

Description

600 - Hydraulische Spritzgießmaschine zur Verarbeitung von Kunststoff, vorzugsweise blähfähiger Thermoplaste Die Erfindung bezieht sich auf Spritzgießmaschinen mit hydraulischer Formschlie3- und Formzuhalteeinrichtung mit einer feststehenden und einer beweglichen Formträgerplatte, wobei letztere auf freitragenden und gegenüber der Hub länge verkurzten Holmen verriegelbar ist und während ihres Offnungshubweges außer Bereich der Holme kommt.600 - Hydraulic injection molding machine for processing plastic, preferably expandable thermoplastics. The invention relates to injection molding machines with hydraulic mold clamping and mold clamping device with a fixed one and a movable mold support plate, the latter on cantilever and opposite the stroke length shortened spars can be locked and during their opening stroke comes out of the area of the spars.

Die Werarbeitung von blährähigen Thermoplasten gestattet die Herstellung von immer gro3stückigeren Teilen, wozu immer größere Maschinen mit entsprechend großen Formen benötigt werden, sodaß auch ie Entformung von GroSspritzteilen zu besonderen Problemen führt, die dadurch erwachsen, da3 bekanntlich die bewegliche For.trägerplatte in holmen geführt wird, die beim Entformen die Zugängigkeit erschweren.The processing of expandable thermoplastics allows production of ever larger parts, for which ever larger machines with corresponding large molds are required, so that also the demolding of large injection-molded parts leads to special problems, which arise from the fact that, as is well known, the movable For.trägerplatte is guided in spars, which make access difficult when demolding.

Um diesen Nachteil zu beseitigen, wurde die Form in der beweglichen Formträgerplatte senkrecht zum Öffnungsweg herausschiebbar angeordnet (0 A S 1 105 152).To overcome this drawback, the shape was made movable Mold carrier plate arranged so that it can be pushed out perpendicular to the opening path (0 A S 1 105 152).

Eine andere möglichkeit wird in dem deutschen Patent Nr. 952 747 gesehen, wo mehrere auf einem Kreis in einer waagerecht im Maschinenoett gelagerte Tragvorrichtung Spritzformen angeordnet sind, um nach dem Verdrehen die Spritzlinge e;trernen zu können.Another possibility is seen in the German patent no. 952 747, where several on a circle in a support device mounted horizontally in the machine oil Injection molds are arranged in order to separate the injection molded parts after twisting can.

Da erstere die Anlage durch zusätzliche Verriegelungen und genaueste Paßarbeiten wesentlich verteuert und anfällig für die Lebensdauer erscheinen läßt und letztere einer beachtlichen Aufwand erfordert, ist es rufgabe der Erfindung, eine möglichkeit zu finden, die, einfach nicht nur in der Herstellung, sondern auch in der Handhaoung, die Zugängigkeit zwecks Entformung, Reinigung und durchzuführende Reparaturen so gestellet, daß weder Verschmutzung noch bedienung den Arbeitsablauf unter schonenster Behandlung vJn W*rk2zug und Spritzling erschweren.Since the former the system through additional interlocks and the most precise Make fitting work appear much more expensive and susceptible to service life and the latter requires considerable effort, it is the object of the invention a way to find that, not just in manufacturing, but also in the handling, the accessibility for the purpose of demoulding, cleaning and to be carried out Repairs are made in such a way that neither contamination nor operation of the workflow with careful treatment of the work piece and injection molding.

Erfindungsgemäß wird die Aufgabe dadurch gebet. da3 die bewegliche Formträgerplatte in an sich bekannter Weise auf einem in Hubrichtung in Maschinenbett auf einem in Hubrichtung im Maschinenbett verfahrbaren wer fahrbaren Schlitten sitzt und um eine n in Schlitten ortsfest angbrauchten vertikalen Zapfen horizontal um 900 verschwenkbar ist.According to the invention, the task is thereby provided. da3 the movable one Mold carrier plate in a manner known per se on a machine bed in the lifting direction on a movable slide that can be moved in the machine bed in the lifting direction and used by one n in the sled vertical tenon can be pivoted horizontally by 900.

Der Aufbau der erfindungsgemäßsn Anlage ist entsprechend der beiliegenden Zeichnungen beispielsweise folgender, wobei Fig 1 eine Ansicht it geschlossener Form und Fig. 2 eine Ansicht mit geschwenkter Form darstellen.The structure of the system according to the invention is according to the enclosed one Drawings, for example, the following, wherein Fig. 1 is a view of it closed Form and Fig. 2 show a view with the form pivoted.

Bekanntlich besteht die Formeinheit aus einer ortsfesten Formträgerplatte 1 und einer beweglichen Formträgerplatte 2, wobei in Abänderung der Zeichnung nach dem deutschen Patent Nr. 1 245 105 die Hubeinrichtung in Form eines Hydraulikæylinders 3 im maschinanbett 4 unterhalb der Formen zu liegen kommt, die einerseits an der ortsfesten Formträgerplatte 1 und andererseits an dem Schlitten 5 befestigt ist, während die Zuhalte- und Öffnungseinrichtung aus den hydraulischen Kolben 6 besteht, die inWder ortsfesten formträgerplatte 1 beweglich lagern und mit einer Ringtraveree 7 gekuppelt sind, die mit den Holmen 8 in fester Verbindung steht, an denen die bewegliche Formträgerplatte 2 verriegelbar ist.As is known, the mold unit consists of a stationary mold carrier plate 1 and a movable mold carrier plate 2, wherein in modification of the drawing according to the German patent no. 1 245 105 the lifting device in the form of a hydraulic cylinder 3 comes to lie in the machine bed 4 below the forms that are on the one hand on the stationary mold carrier plate 1 and on the other hand is attached to the carriage 5, while the locking and opening device consists of the hydraulic piston 6, The stationary mold carrier plate 1 can be stored in a movable manner and with a ring traveree 7 are coupled, which is firmly connected to the spars 8, on which the movable mold carrier plate 2 is lockable.

Die bewegliche Foreträgerplatte 2 sitzt in an sich bekannter Weise auf einem in Hubrichtung is maschinenbett 4 verfahrbaren Schlitten 5 und ist um einen im Schlitten 5 ortsfest angebrachten vertikalen Zapfen 9 horizontal verschwenkbar, wozu beispielsweise ein Hydrai,likzylinder 10 mit Zahnatangenkolbenstange, die in einen Zahnsegmentkranz 11 an der beweglichen Formträgerplatte 2 angreift, vorgesehen ist, die gleichzeitig durch den Hydraulikzylinder 10 in SchlieG- und Entformstellung gehalten wird mit dieser erfindungsgemäßen Schwenkeinrichtung und der Anordnung der Bewegungseinrichtungen ist mit einfachen Mitteln eine zuverlässige Anlage in kurzer Bauweise entstanden, wodurch die möglichkeit besteht, nicht nur das Entformen in ungestörter Leise und ungefährlich durchzufuhren, sondern auch Werkzeug und diarkstück in guter Sicht beobachten und eventuell reparieren zu können, wobei das Verschwenken der Trägerplatte in weniger anfälliger Form möglich geworden ist.The movable forum carrier plate 2 sits in a manner known per se on a carriage 5 which can be moved in the lifting direction is machine bed 4 and is up a fixedly mounted vertical pin 9 in the slide 5 can be pivoted horizontally, including, for example, a hydraulic cylinder 10 with a toothed piston rod, which is shown in a ring gear 11 on the movable Mold carrier plate 2 attacks, is provided, which is simultaneously closed by the hydraulic cylinder 10 and demolding is held with this pivoting device according to the invention and the arrangement of the movement devices is reliable with simple means Plant in a short construction, which gives the possibility, not only to carry out the demolding in undisturbed quiet and harmlessly, but also To be able to observe the tool and the diark piece with a good view and possibly repair it, whereby the pivoting of the carrier plate has become possible in a less susceptible form is.
