The process for making an i.c. engine block from a light alloy such as aluminium alloy consists of forming a mould cavity (10) with at least one sleeve (7) positioned in it to form an engine cylinder and for filling the cavity, the molten alloy being fed into the cavity through both the interior and exterior of the sleeve. The mould cavity is filled under pressure, with the molten alloy fed into it through the surface that corresponds to the base of the engine block, and with the sleeve held by an inner support (9) that leaves at least one passage for pouring the alloy that forms the upper part of the block.

Description

La présente invention concerne d'une façon générale le moulage de pièces en alliage léger tel qu'un alliage d'aluminium et plus particulièrement le moulage de pièces possédant des inserts métalliques. Plus particulièrement, il s'agit de blocs moteurs de moteurs à combustion interne comportant des inserts constitués par des chemises de cylindres.The present invention generally relates to the molding of light alloy parts such as an aluminum alloy and more particularly the molding of parts having metal inserts. More particularly, these are engine blocks of internal combustion engines comprising inserts consisting of cylinder liners.

Pour la réalisation de certaines pièces en aluminium moulé, par exemple les blocs moteurs, il est actuellement nécessaire d'utiliser à certains endroits des inserts en un matériau autre que celui utilisé pour le moulage de la pièce.For the production of some molded aluminum parts, for example engine blocks, it is currently necessary to use in some places inserts made of a material other than that used for molding the part.

Dans le cas des blocs moteurs en alliage léger, la technologie la plus répandue consiste ainsi à insérer les chemises en fonte, qui assurent le contact avec les segments des pistons, dès la coulée.In the case of light alloy engine blocks, the most widespread technology is to insert the cast iron liners, which ensure contact with the piston rings, as soon as casting.

Pour ce faire il convient de donner à l'insert une surface d'accrochage mécanique satisfaisante, par exemple par usinage d'une gorge hélicoïdale sur la surface externe de la chemise. Si l'aluminium liquide pénètre bien dans ces reliefs, la tenue mécanique de l'ensemble est obtenue de façon satisfaisante.To do this, it is necessary to give the insert a satisfactory mechanical attachment surface, for example by machining a helical groove on the outer surface of the jacket. If the liquid aluminum penetrates well into these reliefs, the mechanical strength of the assembly is obtained satisfactorily.

Or, il apparaît que les procédés de fabrication utilisés aujourd'hui et notamment le procédé par coulée sous pression de l'aluminium dans des moules métalliques ne permettent pas d'obtenir une haute qualité métallurgique notamment en terme de fissures et autres micro-porosités dans les régions de la pièce telles que le haut des cylindres, c'est-à-dire la zone où l'aluminium vient recouvrir les chemises et ce, quelle que soit la forme donnée aux talons de lavage disposées dans ces zones. Ceci est susceptible d'entraîner des taux élevés de rebuts.However, it appears that the manufacturing processes used today and in particular the process by die casting of aluminum into metal molds do not allow to obtain a high metallurgical quality especially in terms of cracks and other micro-porosities in the parts of the room such as the top of the cylinders, that is to say the area where the aluminum comes to cover the shirts and this, regardless of the shape given to the washing heels arranged in these areas. This is likely to result in high rejection rates.

En effet, l'existence de défauts dans cette zone s'avère préjudiciable lors de la mise en place des segments : des particules peuvent se détacher et rayer la chemise, ce qui n'est pas tolérable.Indeed, the existence of defects in this area is detrimental when setting up segments: particles can come off and scratch the shirt, which is not tolerable.

La présente invention a pour objet de pallier ces limitations de l'état de la technique et de permettre d'obtenir une bonne qualité métallurgique dans la zone du haut des cylindres.The present invention aims to overcome these limitations of the state of the art and to obtain a good metallurgical quality in the area of the top of the cylinders.

Le procédé de fabrication d'un bloc moteur de moteur à combustion interne à cylindres en alliage léger tel qu'un alliage d'aluminium selon l'invention est caractérisé en ce qu'il comprend les étapes de former une cavité de moule à l'intérieur de laquelle est disposée au moins une chemise rapportée destinée à former au moins un cylindre dudit moteur et d'alimenter ladite cavité en alliage liquide, le liquide remplissant la cavité à la fois par l'intérieur de la chemise et par l'extérieur de la chemise.The method for producing a light alloy cylinder internal combustion engine engine block such as an aluminum alloy according to the invention is characterized in that it comprises the steps of forming a mold cavity at the inside which is disposed at least one attached sleeve intended to form at least one cylinder of said motor and to feed said liquid alloy cavity, the liquid filling the cavity both by the inside of the jacket and by the outside of shirt.

Selon une autre caractéristique du procédé fabrication d'un bloc moteur objet de la présente invention, l'alimentation de la cavité de moule est opérée sous pression, et en ce que l'alliage est introduit par la face du moule correspondant à la face inférieure du bloc moteur.According to another characteristic of the manufacturing process of a motor block which is the subject of the present invention, the feeding of the mold cavity is carried out under pressure, and in that the alloy is introduced by the face of the mold corresponding to the lower face. of the engine block.

Selon une autre caractéristique du procédé fabrication d'un bloc moteur objet de la présente invention, la chemise est portée par une pièce support s'étendant à l'intérieur de la chemise et en ce que la pièce support est conformée pour laisser au moins un passage pour l'alliage.According to another characteristic of the manufacturing process of a motor block object of the present invention, the liner is carried by a support piece extending inside the liner and in that the support piece is shaped to leave at least one passage for the alloy.

Selon une autre caractéristique du procédé fabrication d'un bloc moteur objet de la présente invention, le passage s'étend le long de la face intérieure de ladite chemise.According to another characteristic of the manufacturing process of a motor block object of the present invention, the passage extends along the inner face of said liner.

Selon une autre caractéristique du procédé fabrication d'un bloc moteur objet de la présente invention, le passage est agencé pour venir alimenter la face supérieure du bloc moteur venant recouvrir le dessus de ladite chemise.According to another characteristic of the manufacturing process of a motor block object of the present invention, the passage is arranged to feed the upper face of the engine block coming to cover the top of said jacket.

Selon une autre caractéristique du procédé fabrication d'un bloc moteur objet de la présente invention, la pièce support est formée par un fût cylindrique et en ce que ce fût comporte à sa périphérie un canal pour le passage de l'alliage.According to another characteristic of the manufacturing process of a motor block object of the present invention, the support piece is formed by a cylindrical barrel and in that it has at its periphery a channel for the passage of the alloy.

Selon une autre caractéristique du procédé fabrication d'un bloc moteur objet de la présente invention, ce canal débouche dans une zone prédéterminée de ladite face supérieure du bloc moteur.According to another characteristic of the manufacturing process of a motor block object of the present invention, this channel opens into a predetermined zone of said upper face of the motor unit.

Selon une autre caractéristique du procédé fabrication d'un bloc moteur objet de la présente invention, ce canal à une profondeur d'environs 1 à 4mm sur une largeur de 1 à 6 cm.According to another characteristic of the manufacturing process of a motor block object of the present invention, this channel to a depth of about 1 to 4mm over a width of 1 to 6 cm.

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 représente une vue synthétique d'une machine à mouler selon l'invention ;
  • la figure 2 représente une vue en perspective d'un fût porte chemise pour machine à mouler selon l'invention.
The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended drawings in which:
  • Figure 1 shows a synthetic view of a molding machine according to the invention;
  • FIG. 2 represents a perspective view of a casing holder for a molding machine according to the invention.

Le processus de moulage d'un bloc moteur (ou carter cylindres) d'un moteur à combustion interne du type multicylindre en alliage d'aluminium est réalisé par une installation industrielle comportant notamment une machine à mouler, un robot d'extraction de la pièce, des moyens de poteyage, un circuit de refroidissement, un four de maintien et un dispositif d'alimentation du type à louche ainsi qu'une presse à dégrapper.The molding process of an engine block (or crankcase) of an internal combustion engine of the multicylinder type of aluminum alloy is carried out by an industrial installation comprising in particular a molding machine, a robot for extracting the workpiece. , potting means, a cooling circuit, a holding furnace and a ladle-type feeder as well as a de-icing press.

Comme il est visible sur la figure 1, la machine ou presse à mouler référencée 1 comporte une empreinte fixe 2 définissant la face inférieure du bloc moteur et une empreinte mobile 3 définissant la face supérieure.As can be seen in FIG. 1, the machine or molding press referenced 1 comprises a fixed imprint 2 defining the lower face of the motor unit and a movable footprint 3 defining the upper face.

L'empreinte fixe est portée par un plateau fixe 4, lequel réalise par ailleurs la fonction d'injection du métal dans le moule par un canal d'injection 5 du métal liquide sous pression.The fixed impression is carried by a fixed plate 4, which also performs the function of injecting the metal into the mold via an injection channel 5 of the liquid metal under pressure.

L'empreinte mobile 3 est elle portée par le plateau mobile 6 de la machine à mouler 1. Le plateau mobile 6 opère par ailleurs le support des chemises 7 avant la coulée et accueille plusieurs sous-ensembles appelés noyaux ou tiroirs 8 réalisant les faces extérieures du bloc. Le plateau mobile 6 coopère par ailleurs avec des moyens d'éjection du bloc non détaillés plus avant.The mobile footprint 3 is carried by the movable plate 6 of the molding machine 1. The movable plate 6 also operates the support of the shirts 7 before casting and accommodates several subassemblies called cores or drawers 8 forming the outer faces of the block. The movable plate 6 also cooperates with block ejection means not further detailed.

Les chemises 7 sont portées par des broches encore appelées fûts porte chemise 9 formés par des cylindriques faisant saillies perpendiculairement à l'empreinte mobile 3 et destinée à recevoir les chemises 7 sur toute la longueur de ces dernières. L'extrémité libre des fûts 9 fait face à l'empreinte fixe 2 du moule.The sheaths 7 are carried by pins also called casing barrels 9 formed by cylindrical protrusions perpendicular to the movable footprint 3 and intended to receive the shirts 7 along the entire length of the latter. The free end of the barrels 9 faces the fixed footprint 2 of the mold.

Les noyaux 8 définissant les faces latérales du bloc moteur sont montés mobiles en translation sous l'action de vérins de sorte qu'à l'ouverture du moule, les noyaux puissent coulisser et libérer la pièce formant le bloc moteur.The cores 8 defining the lateral faces of the motor unit are mounted to move in translation under the action of jacks so that at the opening of the mold, the cores can slide and release the part forming the motor unit.

Ainsi donc la machine à mouler définit une cavité de moulage 10 délimitée principalement par les empreintes 2 et 3, les tiroirs 8, les chemises 7 et les fûts 9. Cette cavité 10 destinée à être remplie par un alliage d'aluminium, est conformée pour que les chemises 7 soient recouvertes d'aluminium à leur extrémité dirigée vers la face supérieure du bloc moteur.Thus, the molding machine defines a molding cavity 10 delimited mainly by the cavities 2 and 3, the drawers 8, the liners 7 and the barrels 9. This cavity 10 intended to be filled with an aluminum alloy, is shaped to that the shirts 7 are covered with aluminum at their end facing the upper face of the engine block.

Le fonctionnement d'une telle machine à mouler est le suivant :The operation of such a molding machine is as follows:

On opère tout d'abord la fermeture du moule, le piston d'injection du mécanisme d'injection sous pression recule et on fait descendre la louche d'alimentation dans le four de maintien de l'aluminium en fusion. La louche alimente ensuite le canal d'injection en alliage liquide.First of all, the closing of the mold is carried out, the injection piston of the injection mechanism under pressure moves back and the feed ladle is lowered into the holding furnace of the molten aluminum. The ladle then feeds the liquid alloy injection channel.

L'injection commence ensuite par une première phase où le métal liquide est amené jusqu'aux attaques de la pièce (vitesse du piston 0,2m/s) puis dans une seconde phase on injecte le métal dans la pièce à vitesse élevée (vitesse du piston 4.5m/s, vitesse aux attaques 60m/s). Le moulage se termine par une phase de compression, la pression dans le métal atteignant 950 bars.The injection then begins with a first phase where the liquid metal is brought to the attacks of the workpiece (piston speed 0,2m / s) and then in a second phase the metal is injected into the workpiece at a high speed (speed of piston 4.5m / s, speed to attacks 60m / s). The molding ends with a compression phase, the pressure in the metal reaching 950 bars.

Cette phase terminée on procède à l'ouverture de la machine, au démoulage des noyaux et à l'éjection du bloc. Il ne reste plus alors qu'à opérer le poteyage et le soufflage des empreintes et insérer les chemises pour recommencer ensuite le cycle de moulage. Le bloc moulé est quant à lui ensuite conduit vers l'outil de dégrappage où il est débarrassé de tous les artifices nécessaires à sa réalisation (masselottes, talons de lavage, coulée, etc.).This completed phase is proceeded to the opening of the machine, the release of the cores and the ejection of the block. All that remains is to do the poteyage and blowing of the imprints and insert the folders to then start the molding cycle again. The molded block is then led to the de-cleaving tool where it is stripped of all the devices necessary for its realization (weights, washing heels, casting, etc.).

Comme cela est représenté à la figure 2, afin de faciliter le passage du métal et faire en sorte que la zone du trottoir d'aluminium recouvrant les chemises (face supérieure ou tablature du carter cylindres) présente une parfaite santé métallurgique et en particulier ne présente pas de fissure, une ou plusieurs veines formant des canaux d'alimentation 91 sont aménagées à la périphérie des fûts 9 de façon à permettre l'alimentation de la zone par l'intérieur des chemises.As shown in Figure 2, to facilitate the passage of the metal and ensure that the area of the sidewalk covering the shirts (upper face or tablature of the crankcase) has a perfect metallurgical health and in particular does not present no crack, one or more veins forming feed channels 91 are arranged at the periphery of the barrels 9 so as to allow the supply of the zone from inside the shirts.

Ces veines 91 sont définies par des usinages de profondeur et de largeur adaptés pratiqués sur la surface des fûts 9 et ce, afin de pouvoir assurer un passage prédéterminé du métal liquide et faciliter ensuite l'élimination du métal lors du dégrappage. Selon l'exemple illustré, le fût comporte une veine d'environ 2cm de large sur 1mm de profondeur. Bien évidemment les dimensions de la veine et le nombre de veine sont adaptées en fonction au cas par cas en fonction des dimensions des moteurs. Ainsi la profondeur peut varier d'environ 1 à 4mm et la largeur de 1 à 6 cm.These veins 91 are defined by machining depth and width adapted made on the surface of the barrels 9 and this, in order to ensure a predetermined passage of the liquid metal and then facilitate the removal of the metal during de-stemming. According to the illustrated example, the barrel has a vein approximately 2 cm wide by 1 mm deep. Obviously the dimensions of the vein and the number of veins are adapted according to the case by case according to the dimensions of the engines. Thus the depth can vary from about 1 to 4mm and the width from 1 to 6 cm.

Lors du remplissage du moule, cette veine 91 permet de venir alimenter et/ou de nettoyer la zone de la tablature directement par l'intérieur de la chemise et ainsi d'assurer une montée rapide en température et/ou un nettoyage de la zone assurant la bonne santé métallurgique de cette dernière.When filling the mold, this vein 91 makes it possible to feed and / or clean the area of the tablature directly from the inside of the jacket and thus to ensure a rapid rise in temperature and / or a cleaning of the zone ensuring the good metallurgical health of the latter.
