Description

PROCEDE DE FABRICATION D'UNE PIECE A DEUX MATERIAUX AFIN D'AMELIORER LE COUPLAGE DES PIECES EN PLASTIQUE AVEC DU METAL EN FEUILLE Le but de cette demande de brevet d'invention est un procédé de fabrication d'une pièce à deux matériaux afin d'améliorer le couplage des pièces en plastique avec du métal en feuille, qui contribue à la fonction à laquelle on consacre différents avantages qui sont listés plus tard, sauf d'autres inhérents à son organisation et sa constitution. L'invention trouve son application dans l'industrie automobile ainsi que pour d'autres véhicules, en particulier dans des intérieurs de porte, bien qu'elle n'exclue pas de nombreuses autres applications industrielles. A présent et en référence à l'état de la technique, il faut mentionner que le couplage des pièces en plastique avec le métal en feuille provoque principalement des problèmes d'ajustement et par conséquent de manque d'esthétique, de bruit, etc. METHOD OF MANUFACTURING A TWO-MATERIAL PART TO IMPROVE THE COUPLING OF PLASTIC PARTS WITH SHEET METAL The purpose of this patent application is a method of manufacturing a two-material part in order to improve the coupling of plastic parts with sheet metal, which contributes to the function to which we devote different advantages that are listed later, except others inherent in its organization and constitution. The invention finds its application in the automotive industry as well as for other vehicles, particularly in door interiors, although it does not exclude many other industrial applications. Now and with reference to the state of the art, it should be mentioned that the coupling of plastic parts with the sheet metal mainly causes adjustment problems and therefore lack of aesthetics, noise, etc.

Le procédé de fabrication d'une pièce à deux matériaux afin d'améliorer le couplage des pièces en plastique avec le métal en feuille, prend en considération ladite pièce à deux matériaux avec du plastique souple dans la périphérie, de cette façon l'esthétique de l'ensemble est amélioré, évitant des défauts de couplage, et le confort est amélioré en supprimant le bruit entre le plastique dur et le métal en feuille, étant donné que la partie souple sert de sous-couche et évite le bruit. Le procédé de fabrication consiste à injecter le matériau dur dans un moule et ensuite, en déplaçant le moule, laisser un espace libre afin d'injecter un matériau souple dans la périphérie de la pièce. The method of manufacturing a two-material part in order to improve the coupling of the plastic parts with the sheet metal, takes into consideration said two-material part with flexible plastic in the periphery, in this way the aesthetics of the assembly is improved, avoiding coupling faults, and the comfort is improved by eliminating the noise between the hard plastic and the sheet metal, since the flexible part serves as an underlayer and avoids the noise. The manufacturing process involves injecting the hard material into a mold and then, moving the mold, leave a free space to inject a flexible material into the periphery of the workpiece.

Afin de compléter la description qui sera faite ci-dessous et afin d'arriver à une meilleure compréhension de ses caractéristiques, on joint un ensemble de plans à cette description qui comprennent sans y être limités les figures qui représentent les détails les plus importants de l'invention. Les figures 1 à 5 représentent des vues correspondant aux phases successives du procédé qui est le sujet de l'invention. In order to complete the description that will be made below and in order to arrive at a better understanding of its characteristics, a set of plans is attached to this description which include, but are not limited to, the figures which represent the most important details of the art. 'invention. Figures 1 to 5 show views corresponding to the successive phases of the process which is the subject of the invention.

La figure 6 représente une vue de la pièce à deux matériaux finie au moyen du procédé de l'invention. La figure 7 représente une vue en perspective et en gros plan d'une application pratique de l'invention. En prenant en considération les figures mentionnées ci-dessus et selon la numérotation adoptée, on peut observer, à titre d'exemple sans y être limité, l'invention qui se compose d'une pièce à deux matériaux afin d'améliorer le couplage des pièces en plastique avec le métal en feuille. Figure 6 shows a view of the finished two-material part by the method of the invention. Figure 7 shows a perspective and close-up view of a practical application of the invention. Taking into consideration the figures mentioned above and according to the numbering adopted, it is possible to observe, by way of example without being limited thereto, the invention which consists of a piece with two materials in order to improve the coupling of the plastic parts with sheet metal.

Le procédé de fabrication consiste à injecter un matériau dur (1) dans un moule (2) et ensuite, en déplaçant ledit moule (2), laisser un espace libre (3) approprié pour injecter un matériau souple (4) dans la périphérie de la pièce (5). The manufacturing method consists in injecting a hard material (1) in a mold (2) and then, by moving said mold (2), leave a free space (3) suitable for injecting a flexible material (4) into the periphery of the mold (2). the room (5).

Sur la figure 1, on peut observer le moule vide (1). La figure 2 représente l'injection du matériau dur (1) dans le moule (2). Les figures 3 et 4 indiquent les premier et second mouvements du moule (2) au moyen de certains séparateurs 30 (6) qui créent l'espace libre (3). Sur la figure 5, on peut observer l'injection du matériau souple (4) dans l'espace libre (3) du moule (2). La figure 6 représente la pièce à deux matériaux (5) déjà finie, avec le matériau dur (1) et le matériau 35 souple (4) dans la périphérie. In Figure 1, one can observe the empty mold (1). FIG. 2 represents the injection of the hard material (1) into the mold (2). Figures 3 and 4 show the first and second movements of the mold (2) by means of some separators (6) which create the free space (3). In Figure 5, one can observe the injection of the flexible material (4) in the free space (3) of the mold (2). Figure 6 shows the already finished two-material part (5) with the hard material (1) and the flexible material (4) in the periphery.

La figure 7 représente une application pratique de ladite pièce à deux matériaux (5) dans l'intérieur du métal en feuille de la porte (7) d'un véhicule. L'invention, dans son essentiel, peut être mise en pratique selon d'autres modes de réalisation qui diffèrent du point de vue des détails avec ce qui est indiqué à titre d'exemple dans la description, et qui atteignent également la protection qui est obtenue. Elle peut par conséquent être réalisée selon n'importe quelle forme et taille et avec les matériaux et les moyens les plus appropriés, tous étant compris dans l'esprit des revendications. Figure 7 shows a practical application of said two-material part (5) into the interior of the sheet metal of the door (7) of a vehicle. The invention, in its essence, can be practiced according to other embodiments which differ from the point of view of the details with that which is indicated by way of example in the description, and which also reach the protection which is obtained. It can therefore be made in any shape and size and with the most appropriate materials and means, all of which are within the spirit of the claims.
