Abstract

The supply channels (6) for delivering hot gas or steam to the press are opened and closed using a blocking device (9) secured to the outside of the bottom part (1) of the press. A non-flowing mixture of chip and/or fiber material with heat-curable binder is delivered to a mold cavity (2) defined by a fixed bottom part, movable top part (3) and sealable cover (4).

Description

Die Erfindung betrifft eine Vorrichtung zur Herstellung von Formteilen aus einem nicht fließfähigen Gemisch von Span-und/oder Faserwerkstoffen und wärmehärtbaren Bindemitteln, welche ein feststehendes Preßwerkzeugunterteil besitzt, an welchem ein den Füllraum umfassendes, rahmenartiges, mit einem Deckel verschließbares Preßwerkzeugoberteil vertikal geführt ist, in dessen zum Füllraum hin gerichteten Wänden Zuführungskanäle vorgesehen sind.The invention relates to a device for production of molded parts from a non-flowable mixture of Chip and / or fiber materials and thermosetting Binders, which is a fixed Has pressing tool lower part, on which the filling space comprehensive, frame-like, with a lid lockable press tool upper part is guided vertically, in its walls facing the filling room Feed channels are provided.

Eine solche Vorrichtung ist bekannt ( EP-A-0 443 053 ).Such a device is known (EP-A-0 443 053).

Sie wird bei der Herstellung von Formteilen aus dem vorstehend genannten Gemisch verwendet, bei welcher das Gemisch vor dem Pressen von in das Preßwerkzeug eingeführte heiße Gase oder Dämpfe bedampft wird.Das Gemisch soll vor dem Pressen des Formteils gleichmäßig von den heißen Gasen oder Dämpfen bedampft werden.
Bei der Herstellung von Formteilen werden üblicherweise wegen deren verschiedenen Formen, unterschiedliche Preßwerkzeugunterteile und Preßwerkzeugoberteile benötigt, welche im Füllzustand entsprechende Füllräume bilden. Es wäre aber zweckmäßig, wenn man die gleiche Presse für das Pressen von unterschiedlichen Formteilen verwenden könnte, wenn die Gestalt gleich ist, sie sich beispielsweise nur in der Dicke unterscheiden.It is used in the production of moldings from the above-mentioned mixture, in which the mixture is vaporized before the pressing of hot gases or vapors introduced into the pressing tool .
When producing molded parts, different press mold lower parts and press mold upper parts are usually required because of their different shapes, which form corresponding filling spaces when filled. However, it would be useful if the same press could be used for pressing different molded parts if the shape was the same, for example they only differ in thickness.

Das der Erfindung zugrunde liegende technische Problem besteht darin, die bekannte Presse in der Weise zu verbessern, daß das gleiche Werkzeug für die Herstellung von Formteilen unterschiedlicher Höhe verwendet werden kann.The technical problem underlying the invention consists of the well-known press in the way improve that same tool for making of molded parts of different heights can be used can.

Diese technische Problem ist erfindungsgemäß dadurch gelöst, daß auf der Außenseite des Preßwerkzeugunterteils eine mit diesem verbundene Sperrvorrichtung der Zuführungskanäle angeordnet ist.This technical problem is according to the invention solved that on the outside of the press tool lower part a connected to this locking device Feed channels is arranged.

Bei der neuen Vorrichtung wird der das Gemisch aufnehmende Füllraum an die Stärke des zu pressenden Formteils angepaßt und die nicht benötigten Zuführungskanäle der heißen Gase oder Dämpfe verschlosssen.
Vorteilhafte Einzelheiten der Erfindung sind in den Ansprüchen 2 bis 4 enthalten. Sie ist nachstehend anhand der in den Figuren 1 und 2 gezeigten Ausführungsbeispielen erläutert. Es zeigen :

Fig. 1
schematisch den Längsschnitt durch ein Ausführungsbeispiel der Vorrichtung mit einem tiefen Füllraum (a) und einem weniger tiefen Füllraum (b),
Fig. 2
schematisch den Längsschnitt durch ein anderes Ausführungsbeispiel der Vorrichtung mit einem tiefen Füllraum (a) und einem weniger tiefen Füllraum (b).
In the new device, the filling chamber which holds the mixture is adapted to the thickness of the molded part to be pressed and the supply channels of the hot gases or vapors which are not required are closed.
Advantageous details of the invention are contained in claims 2 to 4. It is explained below using the exemplary embodiments shown in FIGS. 1 and 2. Show it :
Fig. 1
schematically the longitudinal section through an embodiment of the device with a deep filling space (a) and a less deep filling space (b),
Fig. 2
schematically shows the longitudinal section through another embodiment of the device with a deep filling space (a) and a less deep filling space (b).

In den Figuren 1 und 2 sind jeweils nur verschiedene Hälften der gleichen Presse gezeigt und zwar eine linke Hälfte (a) und eine rechte Hälfte (b).In Figures 1 and 2 are only different Shown halves of the same press, namely a left one Half (a) and a right half (b).

Die Presse besitzt ein Preßwerkzeugunterteil (1). An diesem ist das den Füllraum (2) umfassende, rahmenartige Preßwerkzeugoberteil (3) vertikal geführt. Es ist mit dem Deckel (4) verschließbar und - wie durch die Pfeile (5) verdeutlicht - vertikal verschiebbar. In den Wänden des Preßwerkzeugoberteils (3) sind die Zuführungskanäle (6) für die heißen Gase angeordnet, welche aus der Sammelleitung (7) gespeist werden. Die Heizungen, von denen beim Pressen der Formteile die benötigte Wärme erzeugt wird, sind mit (8) bezeichnet.The press has a press tool lower part (1). On this is the frame-like structure that encompasses the filling space (2) Pressing tool upper part (3) guided vertically. It is with that Cover (4) can be closed and - as indicated by the arrows (5) clarified - vertically movable. In the walls of the Press tool upper part (3) are the feed channels (6) arranged for the hot gases, which from the Bus line (7) are fed. The heaters, by the heat required when pressing the molded parts generated are designated by (8).

Auf der Außenseite des Preßwerkzeugunterteils 1 ist eine Sperrvorrichtung der Zuführungskanäle (6) angeordnet, welche bei dem in Fig. 1 gezeigten Ausführungsbeispiel aus der Platte (9) besteht, welche mit dem Preßwerkzeugunterteil 1 verbunden ist. Die Platte (9) wird an die Innenfläche des Preßwerkzeugoberteils (3) angedrückt, wie die Druckfedern (10) verdeutlichen. On the outside of the lower die 1 is one Blocking device of the feed channels (6) arranged, which in the embodiment shown in FIG. 1 the plate (9), which with the Pressing tool lower part 1 is connected. The plate (9) is to the inner surface of the press tool upper part (3) pressed on, as the compression springs (10) illustrate.

Wie aus Fig. 1 zu erkennen ist, nehmen Preßwerkzeugunterteil 1 und Preßwerkzeugoberteil 3 im linken Teil der Presse (a) eine solche Stellung zueinander ein, daß ein großer Füllraum (2) entstanden ist. Die Platte (9) nimmt eine solche Stellung ein, daß alle Zuführungskanäle (6) beim Bedampfen des im Füllraum (2) vorhandenen Gemisches teilnehmen können.As can be seen from Fig. 1, take Pressing tool lower part 1 and pressing tool upper part 3 in left part of the press (a) such a position to each other a that a large filling space (2) has arisen. The Plate (9) occupies such a position that all Feed channels (6) when steaming in the filling chamber (2) existing mixture can participate.

Beim rechten Teil der Presse (b) weist der Füllraum (3) durch die vertikale Absenkung der Preßwerkzeugoberteils (3) eine geringere Füllhöhe auf. Die nicht für das Bedampfen des Gemischs benötigten Zuführungskanäle (6) sind von der Platte (9) verschlossen.On the right part of the press (b), the filling chamber (3) due to the vertical lowering of the upper part of the press tool (3) a lower fill level. Not for that Steaming the mixture required supply channels (6) are closed by the plate (9).

In Fig. 2 sind die gleichen Teile der Presse mit den gleichen Bezugszeichen wie in Fig. 1 versehen. Die in Fig. 2 gezeigte Presse unterscheidet sich von der in Fig.1 gezeigten Presse dadurch, daß anstelle der Platte (9) in den Sammelleitungen (7) vertikal verschiebbare Abdichtstößel (11) vorhanden sind. Diese können entweder starr mit dem Preßwerkzeugunterteil gekoppelt sein oder separat einstellbar sein.In Fig. 2 are the same parts of the press with the the same reference numerals as in Fig. 1 provided. The in Fig. 2 shown press differs from that in Fig.1 shown press in that instead of the plate (9) in the manifolds (7) vertically displaceable Sealing plunger (11) are available. These can either be rigidly coupled to the press tool lower part or be adjustable separately.
