Abstract

The mould unit (1) producing plastic foam mouldings comprises at least three die platen bodies (3, 4, 5) in series, perpendicular to the moulding machine (2) closure direction. The bodies have tool faces (6, 7) forming the thermoplastic foam to mouldings. One body (3) is fixed, and the others move between open and closed positions, about two planes of moulding tool separation (8, 9), where the moulding is formed. One moving die platen body (4), the central one, has adaptable construction.

Description

Die Herstellung von Formteilen aus thermoplastischem Schaumkunststoff mittels Formvorrichtungen die im wesentlichen zweiteilig sind und durch eine arretierte Formhälfte, die Festseite und eine bewegliche Formhälfte, die Fahrseite beschrieben sind, ist bekannt.The production of molded parts from thermoplastic foam plastic using molding devices which are essentially in two parts and by a locked mold half, the fixed side and one movable mold half, the driving side are described is known.

Um die Kapazität der Formgebungsmaschine rationell zu nutzen, ist es Stand der Technik, in der Form­ vorrichtung mehrere Formnester anzuordnen. Diese Formvorrichtungen sind dem Fachmann als Mehrfachwerkzeuge bekannt.In order to use the capacity of the molding machine efficiently, it is state of the art in the mold device to arrange several mold nests. These molding devices are known to those skilled in the art Multiple tools known.

Mehrfachwerkzeuge dieser Art sind geeignet, die vom Maschinenhersteller angegebene projizierte Kapazität zu nutzen.Multiple tools of this type are suitable, the projected specified by the machine manufacturer Capacity to use.

Es handelt sich dabei um die Nutzung der Kapazität , die durch die projizierte Aufspannfläche bestimmt ist.It is the use of the capacity that is determined by the projected clamping surface is.

Sind die aus thermoplastischem Schaumkunststoff herzustellenden Formteile von überwiegend flacher, flächiger Konfiguration, so hat dies zur Folge, daß die projizierte Einbauhöhe der Formgebungsmaschine nicht optimal genutzt wird. Dies kann zur Folge haben, daß die Kapazität der Formgebungsmaschine nicht im möglichen Maße ausgeschöpft wird.Are the molded parts to be produced from thermoplastic foam plastic of predominantly flat, flat configuration, this has the consequence that the projected installation height of the molding machine is not used optimally. This can result in the capacity of the molding machine is not exhausted to the extent possible.

Der im Patentanspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde, die Kapazität von Form­ gebungsmaschinen für die Herstellung von Formteilen aus thermoplastischem Kunststoff, aus Schaum­ kunststoff maximal auszuschöpfen.The invention specified in claim 1 is based on the object, the capacity of form machine for the production of molded parts from thermoplastic, from foam maximum use of plastic.

Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch 1 aufgeführten Merkmale gelöst.This object is achieved by the features listed in claim 1.

Die mit der Erfindung erreichten Verbesserungen und Vorteile bestehen insbesondere darin, daß der Nutzungsgrad der Formgebungsmaschine, deren Produktivität ganz entscheidend erhöht wird und daß die Selbstkosten für die Herstellung von Formteilen, bezogen auf ein Formteil, entscheidend gesenkt werden.The improvements and advantages achieved with the invention are in particular that the Efficiency of the molding machine, the productivity of which is significantly increased and that the cost of producing molded parts in relation to a molded part was significantly reduced will.

Die Herstellung von Formteilen mittels der erfindungsgemäßen Formvorrichtung erfordert für die gleiche Anzahl Formteile eine geringere Anzahl Formgebungsmaschinen.The production of molded parts by means of the molding device according to the invention requires the same Number of molded parts a smaller number of molding machines.

Auch die auf die Formvorrichtung selbst bezogenen Kosten pro Formteil werden durch die Erfindung ganz entscheidend gesenkt.The costs per molded part relating to the molding device itself are also reduced by the invention lowered significantly.

Durch die im Patentanspruch 5 angegebene Adaptabilität eines beweglichen Formaufspannkörpers ob­ liegt es dem Fachmann, die somit gegebene Kompatibilität der Formvorrichtung auch zu unterschied­ lichen Formteilvariationen zu nutzen und so die Kosten für die Fertigung der Formvorrichtung zu mini­ mieren.Due to the adaptability of a movable mold body specified in claim 5 it is up to the person skilled in the art to differentiate the compatibility of the molding device that is thus given Lichen molded part variations to use and so the cost of manufacturing the molding device to mini lubricate.

Die kontur- und formgebenden Teile der Formvorrichtung sind modulartig variierbar.The contour and shape-giving parts of the molding device can be varied in modules.

Die Nutzung dieser Eigenschaft ist besonders dann vorteilhaft, wenn es gilt Formteile herzustellen, die sich in den Parametern Schwindung und Formteildichte sowie Restfeuchtigkeit in einem engen Toleranz­ bereich bewegen müssen. Dies ist besonders dann von Bedeutung, so es sich um Einzelformteile aus thermoplastischem Schaumkunststoff handelt, die zu fügen und mit einem Überzug zu kaschieren sind, z. B. Sonnenblenden o. ä. Ausstattungsteile für den Fahrzeugbau. The use of this property is particularly advantageous when it comes to producing molded parts that the parameters of shrinkage and molded part density as well as residual moisture within a narrow tolerance have to move the area. This is particularly important when it comes to individual molded parts thermoplastic foam plastic that has to be joined and covered with a covering, e.g. B. Sun visors or similar equipment for vehicle construction.  

Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles näher erläutert.The invention is explained in more detail below using an exemplary embodiment.

Es zeigt in der Zeichnung:It shows in the drawing:
