Formgestell für Spritzgußformen:Mold frame for injection molds:

Zur Herstellung von Spritzgußformen werden Formgestelle verwendet, die in standartisierter Ausführung als handelsübliches Erzeugnis angeboten werden.For the production of injection molds mold frames are used that are offered in a standardized version as a commercially available product.

Derartige Formgestelle sind in den verschiedensten Ausführungen am Markt, wobei die Funktion auf das allen Formen gemeinsame Prinzip beruht. Zwei Formhälften, ein Formoberteil mit einem Formunterteil ist über Säulenführungen und Führungsbuchsen verbunden.Such mold frames are available in a wide variety of designs, whereby the function is based on the principle common to all forms. Two mold halves, an upper mold part with a lower mold part, is via column guides and guide bushings connected.

Das im Erfindungsgegenstand dargestellte Formgestell für Spritzgußformen weist einige Charakteristiken auf, die in Bezug auf Verwendung und Herstellung Vorteile bieten, wobei auch die äußere Form ansprechend wirkt.The mold frame for injection molds shown in the subject matter of the invention has some characteristics related to use and manufacture Offer advantages, whereby the external shape is also appealing.

Die aus Guß gefertigten Ober- und Unterteile der Form, weisen einen quadratischen Aufbau auf, in die die Formplatten eingreifen und in diesen zentriert sind. Durch das Überstehen des quadratischen Aufbau über das Formplattenlager werden die im Aufbau untergebrachten Führungsbuchsen und Führungssäulen so nahe aneinander gebracht, daß sich eine zuverlässige Führung der beiden Formhälften zu einander ergibt.The cast upper and lower parts of the mold have a square shape Structure in which the mold plates engage and are centered in them. By protruding the square structure over the mold plate bearing the guide bushings and guide columns housed in the structure are brought so close to one another that a reliable Leading the two mold halves to each other results.

Das Formgestell ist mit 4 Führungssäulen ausgestattet, sofern sie als Zweiplattenform arbeitet.The molded frame is equipped with 4 guide pillars, provided they are Two-platen form works.

Sie ist aber auch als Dreiplattenform verwendbar. In diesem Fall dienen zwei diagonal gegenüberliegende Führungssäulen zur Führung, während in den anderen gegenüberliegenden Bohrungen Begrenzungssäulen untergebracht sind, die einerseits zur Wegbegrenzung, andererseits zur Entriegelung der beweglichen Formplatte dienen.But it can also be used as a three-plate shape. In this case serve two diagonally opposite guide pillars for guidance, while in the other opposite bores delimitation columns are housed, on the one hand to limit the path, on the other hand to unlock the movable mold plate are used.

Beide Formhälften sind mit 4 angegossenen Segmenten ausgestattet, die das Einspannen der Form in die Maschine erleichtern.Both mold halves are equipped with 4 cast-on segments that make it easier to clamp the mold in the machine.

Das Formgestell für Spritzgußformen besteht aus dem Formoberteil 1 und dem Formunterteil 2, die beide mit den die Form charakterisierenden quadratischen oder rechteckigen Aufbauten 3 ausgerüstet sind. Zwischen den Formplatten Ober- und Unterteil, liegt die Düsenplatte 4, die bewegliche Formplatte 5 und die Auswerferpfatte 6. Die Formplatten 4 und 6 sind in den Aufbauten 3 zentiert untergebracht, sodaß sich ein zentrischer Sitz der Formplatten ergibt. Das Formunterteil weist die diagonal gegenüberlieg en denAusfräsungen 7 auf, in die die Halteknaggen 8 über den -Stift 9 drehbar gelagert sind. Die Blattfeder 10 drückt die Halteknaggen in Eingriff, wobei die bewegliche Formplatte 5 von den Halteknaggen erfaßt und festgehalten wird.The mold frame for injection molds consists of the upper mold part 1 and the lower part of the mold 2, both with the square characterizing the shape or rectangular structures 3 are equipped. The nozzle plate 4, the movable one, is located between the upper and lower part of the mold plates Mold plate 5 and the ejector plate 6. The mold plates 4 and 6 are in the superstructures 3 housed centered, so that there is a central seat of the mold plates. The lower part of the mold has the diagonally opposite cutouts 7, in which the retaining lugs 8 are rotatably mounted on the pin 9. The leaf spring 10 presses the retaining lugs into engagement, with the movable mold plate 5 is grasped and held by the retaining lugs.

Die Begrenzungssäule 11 mit dem Bund 12, dient zur Begrenzung der beweglichen Formplatte und Ihrer Entriegelung. Den Abschluß des Formgestell bildet der Flansch 13, der durch Schrauben die Formplatte 6 mit dem Formunterteil 2 fest verbindet. An die Formober- und Unterteile, sind je 4 Flanschsegmente angegossen.The delimitation column 11 with the collar 12 is used to limit the movable Mold plate and your release. The end of the mold frame is formed by the flange 13, which screws the mold plate 6 to the lower part of the mold 2 firmly connects. 4 flange segments are cast onto each of the upper and lower parts of the mold.

Zur Kühlung der Formplatten sind im Formober- und Unterteil, Rillen 15 eingegossen, die durch einlegen von Dichtungen gegen die Formplatten gedichtet werden können, lh vielen Fällen reicht diese Formkühlung aus, sodaß Kühlbohrungen in den Formplatten entfallen können. Die Auswerferplatten 16, dienen zur Entformung der Spritzteile.For cooling the mold plates, grooves 15 are provided in the upper and lower parts of the mold poured in, which can be sealed against the mold plates by inserting gaskets, lh in many cases this mold cooling is sufficient so that Cooling holes in the mold plates can be dispensed with. The ejector plates 16 are used to demold the molded parts.

Der außerordentliche einfach und unkomplizierte Aufbau des Formgestelles verbindet die Vorteile der leichten Herstellbarkeit mit dem Vorteil der vielseitigen Verwendungsmöglichkeit.The extraordinarily simple and uncomplicated structure of the molded frame combines the advantages of easy manufacturability with the advantage of versatile Possible use.
