Abstract

Production of a sandwich plate, using a lower mold (10) providing the contour of the plate and an upper mold (8) with injection and deaeration nozzles, involves successively applying coarse fabric layer(s) (6), strengthening plate(s) (7) and further coarse fabric layer(s) to the interior of the lower mold; tightly closing the upper mold (if necessary after spraying with gel coat) onto the lower mold; injecting casting resin (12) through the injection nozzle; sucking out air via the deaeration nozzle; and hardening the plate in the mold. Production of a sandwich plate, using a lower mold (10) providing the contour of the plate and an upper mold (8) with injection and deaeration nozzles, involves: (1) applying coarse fabric layer(s) (6) on the inside of the lower mold (if necessary after spraying with a gel coat and optionally further covering with fine fabric layer(s); (2) applying reinforcing plate(s) (7) to provide insulation and dimensional stability; (3) applying coarse fabric layer(s) (6), optionally followed by applying fine fabric layer(s); (4) tightly closing the upper mold (if necessary after spraying with gel coat) onto the lower mold; (5) injecting casting resin (12) into the mold through the injection nozzle; (6) sucking air from the mold via the deaeration nozzle; and (7) hardening the sandwich plate in the mold. Independent claims are included for: (A) a variant of the process, in which the upper mold does not have an injection nozzle and (instead of injection of the resin) a thin layer of resin is applied to the fabric layer-reinforcing plate-fabric layer assembly before closing the mold; (B) the production of adapted frames (3) for the reverse side of door panels, by covering the indentations for the frame in a lower mold with fabrics, optionally applying a filling (11), closing the mold at the exterior side with a rotated upper mold and injecting resing, deaerating and hardening as above; and (C) a variant on the frame production process, in which the mold is closed with a separate upper mold for multiple models of frames and multiple injection nozzles are optionally used.

Description

Die Erfindung beschreibt ein Verfahren zur Herstellung von Sandwichplatten, insbesondere für Türfüllungen, in einer Form mit einer Unterform, welche die Kontur der Sandwichplatte vorgibt, und einer Oberform, die mit Injektionsdüse und Entlüftungsdüse versehen ist.The Invention describes a process for the production of sandwich panels, especially for door panels, in a mold with a lower mold showing the contour of the sandwich panel and an upper mold provided with injection nozzle and vent nozzle.

Türfüllungen werden in Sandwichbauweise hergestellt, um die Anforderungen an Wärmedämmung, Stabilität und Optik zu erfüllen. Dabei werden normalerweise auf Kompaktschaumplatten zwei Deckschichtplatten aus glasfaserverstärktem Kunststoff (GfK) aufgeklebt und alle miteinander verpresst. Nach der Aushärtung der Klebers kann die Türfüllung weiter bearbeitet werden. Daneben werden Rahmen von Lichtausschnitten in separaten Formen hergestellt. Aus der Türfüllung werden die Lichtausschnitte herausgearbeitet und die Rahmen aufgeklebt. Danach wird die gesamte Türfüllung geschliffen und lackiert.door panels are manufactured in sandwich construction to meet the requirements Thermal insulation, stability and appearance to fulfill. Normally, two cover sheets are used on compact foam boards made of glass fiber reinforced Glued plastic (GfK) and all pressed together. To the curing the glue can continue the door paneling to be edited. In addition, frames of light cutouts in made of separate molds. From the door panel, the light cutouts are worked out and the frame glued on. Thereafter, the entire door panel is ground and painted.

Aus der Patentschrift DE 197 17 508 ist bekannt, einen Abdeckrahmen an eine vorhandene Türfüllung anzugießen. Dazu müssen aber zusätzliche Rinnen in die Form eingebracht werden, um den Abdeckrahmen an der Türfüllung zu verankern.From the patent DE 197 17 508 It is known to apply a cover to an existing door panel. For this purpose, however, additional grooves must be introduced into the mold in order to anchor the cover frame to the door panel.

Es ist Aufgabe der Erfindung, ein Verfahren anzugeben, bei dem eine Sandwichplatte, insbesondere für Türfüllungen, optional mit den Lichtausschnitten und den zugehörigen Rahmen, in einer Form in einem Arbeitsgang hergestellt wird.It Object of the invention to provide a method in which a Sandwich plate, especially for Door panels, Optionally with the light cutouts and the associated frame, in a shape produced in one operation.
