Description

Formvorrichtung zum Herstellen von Formteilen aus thermoplastischem SchaumkunststoffMoulding device for producing moulded parts made of thermoplastic foam

> Formvorrichtungen herkömmlicher Bauart für das Herstellen von Formteilen aus thermoplastischem und schäumbarem Kunststoff sind im wesentlichen zweiteilig und durch eine arretierte Formhäifte, die Festseite, und eine bewegliche Formhälfte, die Fahrseite, beschrieben. Bei geschlossener Formvorrichtung ist die Kavität ausgebildet. > Conventional molding devices for producing molded parts from thermoplastic and foamable plastic are essentially two-part and are characterized by a locked mold half, the fixed side, and a movable mold half, the travel side. When the molding device is closed, the cavity is formed.

Um partiell am Formteil eine höhere Dichte des geschäumten Kunststoffs und dadurch eine höhere Festigkeit zu erzeugen, ist es üblich, die Formvorrichtung, vornehmlich deren bewegliche Formhälfte, mit stempelartigen Schiebern auszustatten. Diese stempelartigen Schieber werden während des Plastifizierens des Kunststoffes, in dessen plastischer Phase betätigt und verdichten partiell den im Formgebungsprozeß befindlichen Kunststoff.
So vermittelt es die OS 3020754.In order to produce a higher density of the foamed plastic on the molded part and thus a higher strength, it is usual to equip the molding device, especially its movable mold half, with stamp-like slides. These stamp-like slides are activated during the plasticizing of the plastic, in its plastic phase, and partially compress the plastic in the molding process.
This is what OS 3020754 says.

In der DE 4414467 wird vorgeschlagen, synchron zum Plastifizierprozeß, das Volumen der Kavität um ca. 50 % dadurch zu reduzieren, daß die Formenrückwand die Funktion eines Kolbens übernimmt und in der Folge der plastische geschäumte Kunststoff verdichtet, verfestigt wird.In DE 4414467 it is proposed, synchronously with the plasticizing process, to reduce the volume of the cavity by approx. 50% by having the mold rear wall take on the function of a piston and, as a result, the plastic foamed plastic is compressed and solidified.

Die vorgenannten Maßnahmen sind jedoch nur bedingt geeignet, die Probleme der qualitativ einwandfreien Ausformung des Kunststoffes in kritischen Bereichen des Formteiles, die durch Hinierschneidungen, Aussparungen uws. definiert sind, zu lösen.However, the aforementioned measures are only partially suitable for solving the problems of qualitatively perfect molding of the plastic in critical areas of the molded part, which are defined by cuts, recesses, etc.

Die Ursache für die mangelhafte Ausformung ist in der Verteilung der zu schäumenden und zum Formteil zu verschmelzenden Kunststoffpartikel in der Kavität der Formvorrichtung begründet. Wenn die Fülldichte der zu verschmelzenden Kunststoffpartikel in den kritischen Bereichen ungenügend ist, sind qualitative Beeinträchtigungen, wie ungenügende Ausformungen oder Festigkeit, die zwangsläufige Folge.The reason for the poor molding is the distribution of the plastic particles to be foamed and melted into the molded part in the cavity of the molding device. If the filling density of the plastic particles to be melted is insufficient in the critical areas, qualitative impairments such as insufficient molding or strength are the inevitable result.

Der im Anspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde, eine Formvorrichtung für das Herstellen von Formteilen aus thermoplastischem und schäumbarem Kunststoff zu schaffen, in deren Kavität die zum Formteil zu formenden, zu plastifizierenden Kunststoffpartikel vor dem Beginn des Plastifizierungsprozesses optimal verteilt und vorverdichtet werden.The invention specified in claim 1 is based on the object of creating a molding device for the production of molded parts made of thermoplastic and foamable plastic, in the cavity of which the plastic particles to be formed into the molded part and plasticized are optimally distributed and pre-compacted before the start of the plasticizing process.

Diese Aufgabe wird mit den Maßnahmen des Anspruchs 1 gelöst.This object is achieved by the measures of claim 1.

Mit der erfindungsgemäßen Formvorrichtung wird erreicht, daß sich das Volumen, der vor dem Erreichen der Endschließstellung der Formvorrichtung mit zu piastifizierenden Kunststoffpartikein gefüllten Kavität, verringert.The molding device according to the invention achieves a reduction in the volume of the cavity filled with plastic particles to be plasticized before the molding device reaches its final closed position.

Mit der Verringerung des Volumens der Kavität geht eine Verteilung und Verdichtung der Kunststoffpartikel in der Kavität einher.The reduction in the volume of the cavity is accompanied by a distribution and compaction of the plastic particles in the cavity.

Die zum Formteil zu formenden und zu plastifizierenden Kunststoffpartikei werden während der Phase bis zum Erreichen der Endschließstellung der Formvorrichtung, jedoch vor dem Beginn der Plastifizierung, in die für eine vollständige und qualitativ einwandfreie Ausformung kritischen Bereichen positioniert. The plastic particles to be formed into the molded part and plasticized are positioned in the critical areas for complete and qualitatively perfect molding during the phase until the molding device reaches its final closed position, but before the plasticization begins.

Nur die vorherige Positionierung und Verdichtung der Kunststoffpartikel in der Kavität der erfindungsgemäßen Formvorrichtung gewährleistet die Hersteilung vollständig ausgeformter und qualitativ einwandfreier Formteile aus geschäumtem Kunststoff.Only the prior positioning and compaction of the plastic particles in the cavity of the molding device according to the invention ensures the production of completely formed and qualitatively flawless molded parts made of foamed plastic.

Formteile aus geschäumtem Kunststpff finden bevorzugt Verwendung als tragende Grundkörper für . Ausstattungsteile im Fahrzeugbau, so z.B. für Armlehnen, Kopfstützen und Sonnenblenden. Sie werden aus funktionellen und ästhetischen Gründen mit einenn Überzug aus textilem und/oder folieähnlichem Material versehen. Das Überzugsmaterial wird häufig mittels Schweißverfahren miteinander verbunden. Die erfindungsgemäße Formvorrichtung, die nach den Ansprüchen 5 bis 11 weitergebildet ist, ermöglicht die Herstellung von Formteilen mit einer umlaufenden Kontur. In dieser Kontur, so sie nutähniich ausgebildet ist, ist z.B. vorteilhaft eine umlaufende Schweißnaht des Überzugmateriales zu positionieren.Molded parts made of foamed plastic are preferably used as supporting base bodies for equipment parts in vehicle construction, such as armrests, headrests and sun visors. They are provided with a cover made of textile and/or film-like material for functional and aesthetic reasons. The covering material is often connected to one another using a welding process. The molding device according to the invention, which is further developed according to claims 5 to 11, enables the production of molded parts with a circumferential contour. In this contour, if it is designed like a groove, it is advantageous to position a circumferential weld seam of the covering material.
