DISPOSITIF DE MOULAGE ET DE FINITION D'UNE PIECE
D'HABILLAGE INTéRIEUR DE VEHICULE AUTOMOBILE
MUNIE D'UN REVETEMENT DECORATIF
L'invention concerne un dispositif de moulage et de finition d'une pièce rhabillage intérieur de véhicule automobile munie d'un revêtement décoratif.DEVICE FOR MOLDING AND FINISHING A WORKPIECE
OF INTERIOR TRIM OF MOTOR VEHICLE
PROVIDED WITH A DECORATIVE COATING
The invention relates to a device for molding and finishing an interior trim part of a motor vehicle provided with a decorative coating.
L'invention trouve plus particulièrement application dans le domaine des dispositifs de moulage de pièces en matière plastique qui portent le cas échéant un tel revêtement.The invention finds more particularly application in the field of devices for molding plastic parts which, where appropriate, carry such a coating.
La publication FR-A-2688442 décrit un exemple de réalisation d'un dispositif de moulage incluant un moule constitué par une matrice qui possède une partie creuse dans laquelle débouche un conduit d'injection d'une matière plastique.Publication FR-A-2688442 describes an exemplary embodiment of a molding device including a mold constituted by a matrix which has a hollow part into which opens a plastic injection pipe.
Lorsque la pièce porte un revêtement décoratifs ce dernier est préalablement déposé dans la cavité de la matrice et adhère à la matière à la suite de l'injection de celle-ci dans le moule.When the part has a decorative coating, the latter is previously deposited in the cavity of the matrix and adheres to the material following the injection of the latter into the mold.
Toutefois lorsque la pièce d'habillage ne porte aucun revêtement additionnel, il importe d'adapter le dispositif de moulage aux différentes variantes de réalisation de telles pièces.However, when the covering part does not carry any additional coating, it is important to adapt the molding device to the different embodiments of such parts.
Les transformations d'outillage génèrent dans ce cas des coûts d'exploitation souvent incompatibles avec les quantités de pièces fabriquées.Tool conversions in this case generate operating costs that are often incompatible with the quantities of parts manufactured.
L'invention a pour objet un dispositif de moulage incluant une matrice dont la partie creuse porte l'orifice de sortie d'un canal d'injection d'une matière plastique et une buse d'injection immobilisée dans ledit orifice.The subject of the invention is a molding device including a die, the hollow part of which carries the outlet orifice of a plastic injection channel and an injection nozzle immobilized in said orifice.
Selon l'invention l'extrémité de la buse s'étend dans le canal d'alimentation de la cavité de formation de la pièce rhabillage et possède une arête de coupe
opérative au contact du revêtement décoratif lors de la fermeture de la matrice par le poinçon du dispositif de moulage.According to the invention the end of the nozzle extends into the supply channel of the formation cavity of the covering part and has a cutting edge
operative in contact with the decorative coating when the die is closed by the punch of the molding device.
Selon une autre caractéristique du dispositif, I'arrêt de coupe s'étend à la périphérie de l'extrémité de la buse et possède des encoches de diffùsion de la matière plastique. According to another characteristic of the device, the cutting stop extends around the periphery of the end of the nozzle and has notches for diffusing the plastic material.
Le dispositif ainsi réalisé possède l'avantage de faciliter la confection de pièces d'habillage nues ou portant un revêtement décoratif.The device thus produced has the advantage of facilitating the preparation of naked trim pieces or those bearing a decorative coating.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description d'un exemple de réalisation du dispositif de moulage en référence aux dessins annexés dans lesquels - la figure 1 est une représentation schématique du dispositif de moulage, - la figure 2 est une représentation à une plus grande échelle de la buse
d'injection utilisée par le dispositif, - la figure 3 est une représentation perspective de l'extrémité de la buse
d'injection, - la figure 4 représente une section partielle de la pièce rhabillage munie
d'un revêtement décoratif réalisée à l'aide du dispositif
La pièce d'habillage représentée à la figure 4 est constituée par un support thermoplastique I portant un revêtement 7. La pièce est obtenue au cours d'un processus de moulage d'une matière thermoplastique préalablement injectée dans un moule 2.Other characteristics and advantages of the invention will appear on reading the description of an exemplary embodiment of the molding device with reference to the accompanying drawings in which - Figure 1 is a schematic representation of the molding device, - Figure 2 is an enlarged representation of the nozzle
injection used by the device, - Figure 3 is a perspective representation of the end of the nozzle
injection, - Figure 4 shows a partial section of the dressing part provided
a decorative covering produced using the device
The covering part shown in FIG. 4 consists of a thermoplastic support I carrying a coating 7. The part is obtained during a molding process of a thermoplastic material previously injected into a mold 2.
Comme représenté à la figure 1 le moule 2 est constitué par une matrice 3 et par un poinçon 4. As shown in FIG. 1, the mold 2 is constituted by a die 3 and by a punch 4.
La matrice 3 possède une cavité 5 de formation de la pièce constituée par une partie creuse ou cavité 5 dans laquelle débouche le conduit d'injection 6 d'une matière thermoplastique.The matrix 3 has a cavity 5 for forming the part constituted by a hollow part or cavity 5 into which opens the injection pipe 6 of a thermoplastic material.
Un revêtement décoratif 7 formé à titre d'exemple par une feuille étirable recouvre la partie creuse 5.A decorative covering 7 formed, for example, by a stretchable sheet covers the hollow part 5.
Un organe de calage déplaçable assure le cas échéant la couverture d'une face de la pièce 1 par le revêtement. Après refroidissement de la pièce 1, on déplace ledit organe de calage dans le sens d'une libération du bord de la pièce 1 lors de l'ouverture du moule.A displaceable wedging member ensures, if necessary, the covering of one face of the part 1 by the covering. After the part 1 has cooled, the said wedging member is moved in the direction of release of the edge of the part 1 when the mold is opened.
Au cours de l'injection, la matière plastique est amenée dans le moule au travers d'une buse 9 immobilisée dans l'orifice de sortie 10 du canal d'injection 6.During the injection, the plastic material is brought into the mold through a nozzle 9 immobilized in the outlet orifice 10 of the injection channel 6.
Selon l'invention l'extrémité de la buse 9 s'étend ainsi que cela est représenté à la figure 2 dans un canal d'alimentation 5A de la cavité 5.According to the invention, the end of the nozzle 9 extends as shown in FIG. 2 in a supply channel 5A of the cavity 5.
Selon une caractéristique de l'invention la buse 9 possède une arête de coupe 1 1 rendue opérative lors de la fermeture de la matrice 3 par le poinçon 4.According to a characteristic of the invention, the nozzle 9 has a cutting edge 1 1 made operative when the die 3 is closed by the punch 4.
Lorsque le moule contient un revêtement décoratif la fermeture du moule a pour effet d'appliquer le revêtement sur l'arête de coupe 11 si bien que celleci perce localement le revêtement 7 ainsi que cela est montré à la figure 2.When the mold contains a decorative coating, closing the mold has the effect of applying the coating to the cutting edge 11 so that it locally pierces the coating 7 as shown in FIG. 2.
La figure 3 montre que l'arête de coupe 11 s'étend à la périphérie de l'extrémité de la buse et possède des encoches 12 de diffision de la matière plastique dans la cavité 5 ou dans le canal d'alimentation 5A.FIG. 3 shows that the cutting edge 11 extends around the periphery of the end of the nozzle and has notches 12 for diffusing the plastic material into the cavity 5 or into the supply channel 5A.
Au cours de rinjection, la matière thermoplastique est uniformément introduite par le canal 6 répartie au contact du revêtement 7. During the injection, the thermoplastic material is uniformly introduced through the channel 6 distributed in contact with the coating 7.
A la suite du refroidissement de la pièce, il est possible d'ouvrir le moule. Le poinçon 4 se soulève avec les éventuelles cales dans le but de libérer le bord 8 du revêtement 7.After the part has cooled, it is possible to open the mold. The punch 4 is raised with the possible shims in order to free the edge 8 of the covering 7.
A cet effet, les cales 20 sont montées à l'extrémité des tiges 13 des vérins hydrauliques 14 à double effet pilotés par des distributeurs 15 à commande électrique.To this end, the shims 20 are mounted at the end of the rods 13 of the double-acting hydraulic jacks 14 controlled by distributors 15 with electrical control.
Le vérin 14 est fixé au poinçon 4 et sa tige 13 s'étend au travers du poinçon 4 jusqu'à la matrice 3.The jack 14 is fixed to the punch 4 and its rod 13 extends through the punch 4 to the die 3.
Le distributeur 15 est actionné par un contacteur fin de course 16 sous l'action de la poussée poinçon 4 à l'ouverture et à la fermeture du moule.The distributor 15 is actuated by a limit switch 16 under the action of the punch punch 4 when the mold is opened and closed.
La figure 1 représente schématiquement le circuit de commande du vérin 14 dans lequel une motopompe alimente le distributeur 15 d'alimentation des chambres de fluide du vérin 14 au cours de la fermeture du contacteur 16.FIG. 1 schematically represents the control circuit of the jack 14 in which a motor-driven pump supplies the distributor 15 supplying the fluid chambers of the jack 14 during the closing of the contactor 16.
Sans sortir du cadre de l'invention il sera bien entendu possible de faire travailler de manière synchrone plusieurs vérins 14 en fonction du degré de finition souhaité de la pièce d'habillage. Without departing from the scope of the invention, it will of course be possible to make several cylinders 14 work synchronously as a function of the desired degree of finish of the covering part.
