Description

La présente invention concerne un insert de fixation pour pièce en matière plastique, l'insert étant du type comprenant un manchon de réception d'un organe de fixation et des moyens de blocage du manchon dans ladite pièce comprennent au moins une collerette prolongeant une extrémité man chon, ladite collerette fournissant une surface d'appui. The present invention relates to a fixing insert for a plastic part, the insert being of the type comprising a sleeve for receiving a fixing member and means for locking the sleeve in said part comprising at least one flange extending a man end. chon, said flange providing a bearing surface.

L'invention s'applique en particulier aux faces avant de véhicules automobiles. The invention applies in particular to the front faces of motor vehicles.

Une telle face avant comprend généralement au moins une pièce matière plastique moulée dans laquelle sont disposés des inserts destinés à recevoir des organes de fixation tels que des vis. Ces inserts permettent ainsi de fixer sur la face avant divers équipements comme, par exemple, un groupe moto- ventilateur, des projecteurs, et un ou plusieurs échangeurs thermiques. Such a front face generally comprises at least one molded plastic part in which are arranged inserts intended to receive fastening members such as screws. These inserts thus make it possible to fix various equipment, such as, for example, a fan motor unit, projectors, and one or more heat exchangers, to the front face.

Généralement, un insert du type précité est réalisé par mise en forme d'une tôle et comprend, avant sa pose, une seule collerette de blocage prolongeant une extrémité du manchon. On introduit cet insert dans pièce en matière plastique préalablement moulée, puis on vient former une deuxième col lerette de blocage à l'autre extrémité du manchon, pour fixer l'insert dans la face avant à la manière d'un rivet. Generally, an insert of the aforementioned type is produced by shaping a sheet and comprises, before its installation, a single locking collar extending one end of the sleeve. This insert is introduced into a plastic part previously molded, then a second collar collar is formed at the other end of the sleeve, to fix the insert in the front face in the manner of a rivet.

L'intégration de tels inserts dans une face avant d'un vehicule au tomobile est donc relativement coûteuse. The integration of such inserts in a front face of a vehicle with a tomobile is therefore relatively expensive.

II est également connu d'utiliser des inserts réalisés par décolle tage, c'est-à-dire usinage sur un tour les uns à la suite des autres à partir d'une barre métallique. Ces inserts ont alors une forme extérieure moletée présentant gorge circulaire intermédiaire centrée sur l'axe du manchon. La matière plastique de la face avant est alors surmoulée sur les inserts. La forme extérieure des inserts assure leur blocage à la fois en rotation et en translation par rapport à la matière plastique qui les entoure. It is also known to use inserts produced by take-off, that is to say machining on a lathe one after the other from a metal bar. These inserts then have a knurled outer shape having an intermediate circular groove centered on the axis of the sleeve. The plastic material of the front face is then molded onto the inserts. The external shape of the inserts ensures their blocking both in rotation and in translation relative to the plastic material which surrounds them.

De tels inserts sont relativement coûteux à réaliser, notamment en raison de leur forme extérieure relativement complexe. Such inserts are relatively expensive to produce, in particular because of their relatively complex external shape.

Un but de l'invention est de résoudre ces problèmes en fournissant un insert de fixation du type précité qui soit de coûts de fabrication et/ou d'intégration dans une pièce en matière plastique réduits. An object of the invention is to solve these problems by providing a fixing insert of the aforementioned type which is of manufacturing and / or integration costs in a reduced plastic part.

A cet effet, l'invention a pour objet un insert de fixation du type pré cité, caractérisé en ce que la collerette comprend une première région fournis- sant ladite surface d'appui et une deuxième région d'ancrage dans la matière plastique de ladite pièce, la deuxième région étant en retrait par rapport à la première région le long de l'axe du manchon. To this end, the subject of the invention is a fixing insert of the aforementioned type, characterized in that the collar comprises a first region providing said bearing surface and a second region for anchoring in the plastic of said piece, the second region being set back from the first region along the axis of the sleeve.

Selon des variantes, l'insert peut comprendre l'une ou plusieurs des caractéristiques suivantes, prise(s) isolément ou selon toutes les combinaisons techniquement possibles - deuxième région est une région périphérique de la collerette ; - collerette est une collerette de blocage du manchon en rotation par rapport à l'axe du manchon par butée contre la matière plastique de ladite pièce ; - collerette a une forme générale qui n'est pas de révolution au tour de l'axe manchon ; - au moins une région de la collerette a un contour de forme géné rale polygonale ; - manchon est taraudé ; - l'insert est obtenu par mise en forme d'une tôle. According to variants, the insert may include one or more of the following characteristics, taken alone or in any technically possible combination - second region is a peripheral region of the collar; - flange is a collar for locking the sleeve in rotation relative to the axis of the sleeve by abutment against the plastic of said part; - collar has a general shape which is not of revolution around the sleeve axis; - at least one region of the collar has a generally polygonal contour; - sleeve is tapped; - the insert is obtained by shaping a sheet.

L'invention a également pour objet un ensemble comprenant au moins une pièce en matière plastique et au moins un insert de fixation, l'insert comprenant manchon de réception d'un organe de fixation et des moyens de blocage du manchon dans ladite pièce qui comprennent au moins une collerette prolongeant une extrémité du manchon, ladite collerette fournissant une surface d'appui qui affleure dans la pièce en matière plastique, et le manchon traversant la pièce en matière plastique, caractérisé en ce que l'insert est un insert que défini ci-dessus. The invention also relates to an assembly comprising at least one plastic part and at least one fixing insert, the insert comprising a sleeve for receiving a fixing member and means for locking the sleeve in said part which comprise at least one collar extending one end of the sleeve, said collar providing a bearing surface which is flush with the plastic part, and the sleeve passing through the plastic part, characterized in that the insert is an insert as defined below -above.

Selon une variante, l'ensemble constitue une face avant pour un véhicule automobile. According to a variant, the assembly constitutes a front face for a motor vehicle.

L'invention a en outre pour objet un procédé de fabrication d'un en semble tel que défini ci-dessus, caractérisé en ce qu'on surmoule ladite pièce en matière plastique sur l'insert de fixation. The invention further relates to a method for manufacturing a set as defined above, characterized in that said plastic part is molded onto the fixing insert.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple, et faite en se référant aux dessins annexés, sur lesquels - la figure 1 est une vue de dessus d'un insert selon l'invention, - la figure 2 est une vue en coupe prise suivant la ligne II-II de la fi gure 1, - la figure 3 est une vue partielle, schématique et en coupe, illus trant la réalisation d'une face avant pour un véhicule automobile incorporant l'insert des figures 1 et 2, et - la figure 4 est une partielle, schématique et en perspective, illustrant la face avant ainsi obtenue. The invention will be better understood on reading the description which follows, given solely by way of example, and made with reference to the appended drawings, in which - Figure 1 is a top view of an insert according to l invention, - Figure 2 is a sectional view taken along line II-II of Figure 1, - Figure 3 is a partial, schematic and sectional view, illustrating the realization of a front face for a motor vehicle incorporating the insert of Figures 1 and 2, and - Figure 4 is a partial, schematic and perspective, illustrating the front face thus obtained.

Les figures 1 et 2 illustrent un insert de fixation 1 pour une face avant d'un véhicule automobile. Figures 1 and 2 illustrate a fixing insert 1 for a front face of a motor vehicle.

Cet insert 1 comprend manchon 2 d'axe A et une collerette 3 prolongeant transversalement l'extrémité supérieure du manchon 2. This insert 1 comprises sleeve 2 of axis A and a flange 3 transversely extending the upper end of the sleeve 2.

Le manchon 2 est de section circulaire et présente intérieurement un orifice traversant 5 circulaire, taraudé, et destiné à recevoir une vis. L'orifice 5 est centré sur l'axe A du manchon 2. The sleeve 2 is of circular section and has internally a circular through hole 5, tapped, and intended to receive a screw. The orifice 5 is centered on the axis A of the sleeve 2.

La collerette 3 comprend depuis le manchon 2 successivement une région intérieure 7, une région intermédiaire 8 et une région périphérique 9. The collar 3 successively comprises from the sleeve 2 an interior region 7, an intermediate region 8 and a peripheral region 9.

La région intérieure 7 étend, depuis le manchon 2, transversale ment à l'axe A vers l'extérieur, et présente un contour périphérique extérieur 10 carré à coins arrondis. The inner region 7 extends from the sleeve 2, transverse to the axis A towards the outside, and has an outer peripheral contour 10 square with rounded corners.

La région intermédiaire 8 s'étend le long de l'axe A et possède une section transversale carrée à coins arrondie. Elle s'étend depuis le contour exté rieur 10 vers le bas. The intermediate region 8 extends along the axis A and has a square cross section with rounded corners. It extends from the outer contour 10 downwards.

La région périphérique 9 s'étend transversalement à l'axe A vers l'extérieur depuis la région intermédiaire 8. La région périphérique 9 présente un contour périphérique intérieur 11 et contour périphérique extérieur 12 qui sont tous les deux de formes carrées à coins arrondis. The peripheral region 9 extends transversely to the axis A outward from the intermediate region 8. The peripheral region 9 has an inner peripheral contour 11 and external peripheral contour 12 which are both square in shape with rounded corners.

L'insert 1 a, par exemple, été obtenu par mise en forme d'une tôle. Pour ce faire, la tôle a par exemple fluotournée pour former à la fois le man chon 2 et son taraudage, puis emboutie pour former la collerette 3 et enfin dé coupée extérieurement le long du contour 12. The insert 1 has, for example, been obtained by shaping a sheet. To do this, the sheet has for example flow-turned to form both the sleeve 2 and its thread, then stamped to form the flange 3 and finally cut outwardly along the contour 12.

Comme illustré par la figure 3, pour intégrer l'insert 1 dans une face avant d'un véhicule automobile, il possible de disposer l'insert 1 à l'intérieur d'un moule 15 d'injection d'une matière plastique qui comprend un demi-moule supérieur 16 et un demi-moule inférieur 17. Le demi-moule supérieur 16 s'appuie sur l'insert par l'intermédiaire de la région 7 de sa collerette 3. Le demi-moule inférieur 17 'appuie sur la tranche inférieure 18 du manchon 2 de l'insert 1. As illustrated in FIG. 3, to integrate the insert 1 into a front face of a motor vehicle, it is possible to place the insert 1 inside a mold 15 for injecting a plastic material which comprises an upper half-mold 16 and a lower half-mold 17. The upper half-mold 16 rests on the insert via the region 7 of its flange 3. The lower half-mold 17 'presses on the lower edge 18 of the sleeve 2 of the insert 1.

II est possible de prévoir, sur l'un ou sur chaque demi-moule 16 17, un relief de positionnement de l'insert 1 qui s'engage dans l'orifice 5 du - chon 2. It is possible to provide, on one or on each half-mold 16 17, a positioning relief of the insert 1 which engages in the orifice 5 of - chon 2.

Pour réaliser la face avant, on injecte une matière plastique 19, exemple polyamide ou du polyéthylène, dans l'empreinte de moulage 20 limitée par demi-moules 16 et 17 et par l'insert de fixation 1. Cette matière plastique 1 entoure alors l'insert 1, en recouvrant entièrement la région inter médiaire 8 la région périphérique 9 de la collerette 3, mais ne pénètre dans l'orifice 5 du manchon 2. To make the front face, a plastic material 19, for example polyamide or polyethylene, is injected into the molding cavity 20 limited by half-molds 16 and 17 and by the fixing insert 1. This plastic material 1 then surrounds the insert 1, completely covering the intermediate region 8 the peripheral region 9 of the collar 3, but does not penetrate into the orifice 5 of the sleeve 2.

Après durcissement de la matière plastique 19 et démoulage, obtient ainsi une face avant 24, partiellement représentée sur la figure 4, comprend une pièce en matière plastique 19 surmoulée sur l'insert 1 et traversee de part en part par le manchon 2. La région intérieure 7 de la collerette 3 et tranche inférieure 18 (non visible sur la figure 4) du manchon 2 affleure dans face avant 24. Les régions intermédiaire 8 et périphérique 9 de la collerette sont noyées dans la matière plastique de la face avant 24. After hardening of the plastic material 19 and demolding, thus obtains a front face 24, partially shown in FIG. 4, comprises a plastic part 19 molded onto the insert 1 and traversed right through by the sleeve 2. The region inside 7 of the collar 3 and lower edge 18 (not visible in FIG. 4) of the sleeve 2 is flush with the front face 24. The intermediate 8 and peripheral 9 regions of the collar are embedded in the plastic of the front face 24.

Ainsi, la région intérieure 7 de la collerette 3 fournit une surface d'appui métallique pour un équipement à fixer sur la face avant 24 par vissage dans l'orifice taraudé 5 du manchon 2. Thus, the interior region 7 of the collar 3 provides a metal bearing surface for equipment to be fixed to the front face 24 by screwing into the threaded orifice 5 of the sleeve 2.

Par ailleurs, on conçoit que les régions 8 et 9 de la collerette 3 (non visibles sur la figure 4) assurent un blocage satisfaisant du manchon 2 dans face avant 24, à la fois en translation et en rotation par rapport à l'axe A du - chon 2, notamment du fait de l'ancrage de l'insert 1 dans la pièce en matière plastique 19 par l'intermédiaire de la région 9 de la collerette 3. Le blocage en rotation est assuré par butée de la collerette 3 contre la matière plastique 19 l'entourant. Furthermore, it can be seen that the regions 8 and 9 of the collar 3 (not visible in FIG. 4) ensure satisfactory locking of the sleeve 2 in the front face 24, both in translation and in rotation relative to the axis A du - chon 2, in particular due to the anchoring of the insert 1 in the plastic part 19 via the region 9 of the collar 3. The rotation lock is ensured by the stop of the collar 3 against the plastic 19 surrounding it.

On constate en particulier que l'insert 1 résiste bien à l'arrachement. In particular, it can be seen that the insert 1 resists pulling out well.

La structure relativement simple de l'insert 1, qui permet sa réalisa tion par mise en forme d'une tôle et son intégration par surmoulage dans une face avant 24, confère à l'insert 1 des coûts de fabrication et de pose relative ment faibles. De plus, le poids de l'insert 1 est réduit. The relatively simple structure of the insert 1, which allows its realization by shaping a sheet and its integration by molding in a front face 24, gives the insert 1 relatively low manufacturing and installation costs. . In addition, the weight of insert 1 is reduced.

Selon des variantes non représentées, les contours 10, 11 et 12 de la collerette 3 peuvent avoir des formes variées, par exemple polygonales, mais de préférence qui ne soient pas de révolution par rapport à l'axe A du manchon 2.According to variants not shown, the contours 10, 11 and 12 of the flange 3 can have various shapes, for example polygonal, but preferably which are not of revolution relative to the axis A of the sleeve 2.
