Abstract
Description
Die Erfindung betrifft ein Spritzgießwerkzeug zur Herstellung von mehrschichtigen flächigen Bauteilen umfassend eine drehbar gelagerte erste Formhälfte, die mit beweglich gelagerten Halteorganen zum Festhalten des gespritzten einschichtigen Formlings versehen ist, eine zweite Formhälfte, die der ersten Formhälfte in einer ersten Drehstellung gegenüberliegend abstandsveränderlich angeordnet und mit einer Düse zum Einspritzen einer ersten Kunststoff-Komponente versehen ist, eine dritte Formhälfte, die der ersten Formhälfte in einer zweiten Drehstellung gegenüberliegend abstandsveränderlich angeordnet ist und mit einer Düse zum Einspritzen einer zweiten Kunststoff-Komponente versehen ist, und mit Einrichtungen zum gesteuerten rotatorischen bzw. translatorischen Bewegen der drei Formhälften.The The invention relates to an injection mold for the production of multilayered flat Components comprising a rotatably mounted first mold half, the with movably mounted holding members for holding the sprayed one-layered molding is provided, a second mold half, the the first half of the mold in a first rotational position opposite distance variable arranged and with a nozzle is provided for injecting a first plastic component, a third mold half, the first half of the mold in a second rotational position opposite distance variable is arranged and with a nozzle for injecting a second plastic component, and with means for controlled rotational or translational movement of the three mold halves.
Bei der Herstellung eines mehrschichtigen flächigen Bauteils mit einem solchen Spritzgießwerkzeug wird zunächst die zweite Formhälfte an der ersten Formhälfte zur Anlage gebracht und in den geschlossenen Formhohlraum wird sodann eine erste Kunststoff-Komponente eingespritzt. Nach dem Erstarren der Kunststoff-Komponente wird die zweite Formhälfte abgehoben bzw. zurückgezogen, und die erste Formhälfte wird zusammen mit dem flächigen einschichtigen Formling verdreht und zum Spritzgießen der zweiten Kunststoff-Komponente mit der dritten Formhälfte in Eingriff gebracht. Während dieses Drehvorgangs besteht die Gefahr, daß der gespritzte einschichtige Formling aus der offenen ersten Formhälfte herausfällt. Beim Stand der Technik wird dies dadurch verhindert, daß mit den in der ersten Formhälfte beweglich gelagerten Halteorganen auf den gespritzten Formling eine seitliche Klemmkraft ausgeübt wird. Das Aufbringen einer solchen seitlichen Klemmkraft auf den noch warmen und plastisch verformbaren Formling ist aber nachteilhaft, weil dadurch in dem erkalteten Bauteil sehr hohe Spannungen entstehen, die zu einer Rißbildung führen können.at the production of a multilayer sheet-like component with such injection mold will be first the second half of the mold at the first half of the mold brought to the plant and in the closed mold cavity is then injected a first plastic component. After solidification the plastic component, the second mold half is lifted or withdrawn, and the first half of the mold becomes along with the flat one-layered Molded twisted and used for injection molding of the second plastic component with the third half of the mold engaged. While This turning process there is a risk that the sprayed single-layered Mold falls out of the open first half of the mold. At the In the prior art, this is prevented by the fact that with in the first half of the mold movably mounted holding organs on the molded molding a lateral clamping force exerted becomes. The application of such a lateral clamping force on the still warm and plastically deformable molding is disadvantageous, because this causes very high voltages in the cooled component, the cracking to lead can.
Der Erfindung liegt die Aufgabe zugrunde, das gattungsgemäße Spritzgießwerkzeug dahingehend weiterzubilden, daß die verschiebbaren Halteorgane den gespritzten einschichtigen Formling beim Verdrehen der ersten Formhälfte gegen ein Herausfallen schützen, ohne dabei jedoch auf diesen eine Klemmkraft auszuüben.Of the Invention is based on the object, the generic injection mold develop further to the effect that the sliding holding members the injected single-layered molding when turning the first half of the mold protect against falling out, but without exerting on this a clamping force.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Halteorgane in der Trennebene der ersten Formhälfte verschiebbar angeordnet und in eine wirksame Stellung vorgespannt sind, in der sie den Rand des gespritzten einschichtigen Formlings übergreifen, und in eine unwirksame Stellung verlagerbar sind, in der sie den Rand des gespritzten einschichtigen Formlings freigeben.According to the invention this Task solved by that the Holding members slidably disposed in the parting plane of the first mold half and are biased into an effective position in which they are the edge of the injected single-layered molding, and into an ineffective one Position are displaced, in which they are the edge of the sprayed single-layered Release molded parts.
Durch diese Ausbildung der Halteorgane wird der gespritzte Formling nicht wie beim Stand der Technik kraftschlüssig, sonder formschlüssig festgehalten. Beim Einspritzen der zweiten Kunststoff-Komponente werden die Halteorgane unter dem Druck der Schmelze zurückgedrängt, so daß die Schmelze den von der ersten und der dritten Formhälfte gebildeten Formhohlraum vollständig ausfüllen kann und mit dem von der ersten Komponente gebildeten Formling bündig abschließt.By This training of the holding organs is not the molded molding as in the prior art non-positively, but held form-fitting. When injecting the second plastic component, the holding organs pushed back under the pressure of the melt, so that the Melt the one formed by the first and third mold halves Mold cavity completely fill out can and flush with the molding formed by the first component.
Die Halteorgane sind vorzugsweise pneumatisch in die wirksame Stellung vorgespannt. Dabei ist die pneumatische Vorspannung zweckmäßiger Weise steuerbar. Dies ermöglicht eine Aufhebung der Vorspannkraft nach dem Schließen der ersten und dritten Formhälte, so daß die Halteorgane unter dem Druck der eingespritzten zweiten Kunststoff-Komponente zuverlässig in die unwirksame Stellung verdrängt werden können.The Holding members are preferably pneumatically in the operative position biased. The pneumatic bias is expedient manner controllable. this makes possible a cancellation of the biasing force after closing the first and third Mold half, So that the Holding members under the pressure of the injected second plastic component reliable displaced into the ineffective position can be.
