La présente invention est relative à une installation de positionnement et de serrage de moules de fonderie.The present invention relates to an installation for positioning and clamping foundry molds.

Plus particulièrement, elle est relative à une installation de positionnement et de serrage de moules de fonderie pour la coulée ascendante sous basse pression d'alliage métallique sur un poste de coulée auprès d'un appareil de fusion d'un alliage métallique.More particularly, it relates to an installation for positioning and clamping foundry molds for ascending casting under low pressure of metal alloy on a casting station with a device for melting a metal alloy.

Il est nécessaire de régler la hauteur de déplacement de moule. Il faut de plus, obtenir le serrage le plus efficace sans fuite de métal liquide.It is necessary to adjust the mold displacement height. It is also necessary to obtain the most effective tightening without leakage of liquid metal.

Afin de conserver la même installation pour plusieurs coulées avec des moules différents, la présente invention propose une installation de serrage utilisable pour des moules de différentes dimensions. Les moules en sable borgnes, comprenant chacun un puits de coulée ouvert vers le bas, alimenté via un nez de coulée relié à une poche de coulée d'alliage métallique, et des moyens pour appliquer la base du puits de coulée sur l'ouverture supérieure du nez de coulée, pouvant être de hauteurs différentes, selon les configurations.In order to keep the same installation for several castings with different molds, the present invention provides a clamping installation which can be used for molds of different dimensions. Blind sand molds, each comprising a downwardly open pouring well, supplied via a pouring nose connected to a metal alloy pouring ladle, and means for applying the base of the pouring well to the upper opening of the pouring nose, which can be of different heights, depending on the configurations.

A cette effet, l'installation telle que définie ci-dessus, se caractérise selon l'invention, en ce qu'elle est constituée, d'au moins un bâti porte moule borgne comprenant un puits de coulée ouvert vers le bas, d'un moyen de transfert en translation, d'au moins un vérin de suspension sensiblement vertical et d'au moins un vérin de serrage sensiblement vertical, le poste de coulée se situant sur le nez de coulée de la poche.To this end, the installation as defined above, is characterized according to the invention, in that it consists of at least one blind mold holder frame comprising a casting well open downwards, a means for transferring in translation, at least one substantially vertical suspension cylinder and at least one substantially vertical clamping cylinder, the casting station being located on the pouring nose of the ladle.

De préférence, l'installation suivant l'invention, du type permettant la coulée répétitive dans lequel le moyen de transfert porte un organe de préhension et de suspension du bâti, est caractérisée en ce que l'organe de préhension et de suspension du bâti du moyen de transfert, comporte le vérin de suspension d'un plateau supérieur du bâti, et sur ce plateau, le vérin de serrage, la tête dirigée vers le bas est liée, libre en rotation, au moyen d'une rotule, à un plateau de serrage.Preferably, the installation according to the invention, of the type allowing repetitive casting in which the transfer means carries a member for gripping and suspending the frame, is characterized in that the member for gripping and suspending the frame of the transfer means, comprises the suspension cylinder for an upper plate of the frame, and on this plate, the clamping cylinder, the head directed downwards is linked, free in rotation, by means of a ball joint, to a plate Clamping.

Suivant d'autres caractéristiques :

  • le plateau supérieur du bâti, sensiblement horizontal, est lié fixement à au moins deux tiges de suspension du moule, descendant sensiblement verticalement, et comprenant chacune à leur extrémité inférieure un taquet tournant, sensiblement horizontal, support de plateau porte-moule du moule. Chaque taquet est escamotable entre une position ouverte du bâti et une position fermée ou de prise sous la face inférieure de plateau porte-moule ;
  • un moule est appliqué par sa face inférieure sur un nez de coulée, se caractérisant en ce qu'au poste de coulée, le moule est appliqué sur la face supérieure d'un dispositif intermédiaire d'usure de façon à assurer une étanchéité parfaite.
According to other characteristics:
  • the upper plate of the frame, substantially horizontal, is fixedly connected to at least two suspension rods of the mold, descending substantially vertically, and each comprising at their lower end a rotating cleat, substantially horizontal, support for the mold-carrier plate of the mold. Each cleat is retractable between an open position of the frame and a closed or gripped position under the underside of the mold carrier plate;
  • a mold is applied by its lower face to a pouring nose, characterized in that at the casting station, the mold is applied to the upper face of an intermediate wear device so as to ensure perfect sealing.

Dans le but de maintenir le plateau porte-moule horizontal, le bâti est guidé verticalement par au moins une tige verticale. De plus les taquets sont étalonnés de façon à ce que les faces d'appui forment un plan horizontal sur lequel vient se placer la plaque porte-moule. Ce plan est perpendiculaire à ladite tige verticale.In order to keep the mold tray horizontal, the frame is guided vertically by at least one vertical rod. In addition, the tabs are calibrated so that the bearing faces form a horizontal plane on which is placed the mold carrier plate. This plane is perpendicular to said vertical rod.

L'invention a encore pour objet une installation de positionnement et de serrage de moule de fonderie en sable borgne pour la coulée ascendante d'alliage métallique ; le moule en sable borgne comprenant un puits de coulée ouvert vers le bas alimenté, via un nez de coulée relié à une poche de coulée d'alliage métallique, et des moyens pour appliquer la base du puits de coulée sur l'ouverture supérieure du nez de coulée caractérisée en ce que l'installation est telle que définie ci-dessus.Another subject of the invention is an installation for positioning and clamping a blind sand foundry mold for the upward casting of metal alloy; the blind sand mold comprising a pouring open open well, via a pouring nose connected to a metal alloy pouring ladle, and means for applying the base of the pouring well to the upper opening of the nose casting characterized in that the installation is as defined above.

Divers détails et avantages de l'invention apparaîtront à la lecture de la description qui va suivre, donnée à titre d'exemple non limitatif, en se référant au dessin annexé, dont la figure unique représente schématiquement une installation de fonderie conforme à l'invention.Various details and advantages of the invention will appear on reading the description which follows, given by way of nonlimiting example, with reference to the appended drawing, the single figure of which schematically represents a foundry installation according to the invention .

L'installation représentée au dessin comprend un bâti 1 dans lequel est fixé un moule borgne 2 comprenant un puits de coulée 3 ouvert vers le bas. Elle est du type permettant la coulée répétitive et comprend en outre, un moyen de transfert horizontal 4 connu tel que, par exemple, le brevet FR-A 2 533 847, breveté par la Demanderesse. Le moyen de transfert porte, selon l'invention, un organe de préhension et de suspension du bâti. L'installation est destinée à positionner et serrer automatiquement de manière répétitive, un moule 2 sur un chenal de coulée ascendante 5.The installation shown in the drawing comprises a frame 1 in which is fixed a blind mold 2 comprising a pouring well 3 open downwards. It is of the type allowing repetitive pouring and further comprises a known horizontal transfer means 4 such as, for example, patent FR-A 2,533,847, patented by the Applicant. The transfer means carries, according to the invention, a member for gripping and suspending the frame. The installation is intended to automatically position and tighten repeatedly, a mold 2 on an upward flow channel 5.

Le bâti 1 comprend à sa partie supérieure un plateau 6, sensiblement horizontal et supposé rectangulaire. Le plateau supérieur 6 est lié fixement à quatre tiges 7 dont deux ne sont pas représentées, de suspension du moule, descendant verticalement, et comprenant chacune à leur extrémité inférieure un taquet horizontal rotatif 8, d'appui du plateau porte-moule 9 du moule 2 ; chaque taquet 8 étant escamotable entre une position ouverte du bâti 1 et une position fermée ou de prise sous la face inférieure 10 du plateau porte-moule 9 du moule 2. Le moule en sable borgne 2 est centré sur le plateau porte-moule 9 et serré entre ledit plateau 9 et la plaque de serrage supérieure 11 au moyen d'un vérin double effet 12 de serrage, dont la tête 13 dirigée vers le bas est liée, libre en rotation, par une rotule 14, à la plaque de serrage 11 du moule 2. Le corps 17 du vérin 12 est lié au plateau 6. La rotation permise par la rotule 14 rend possible l'utilisation de moule dont la face supérieure, représentée en traits pointillés mixtes, est dans un plan incliné par rapport au plan de la face inférieure. La face inférieure de la plaque supérieure 11 étant plus grande ou de même dimension que la face supérieure du moule 2.The frame 1 comprises at its upper part a plate 6, substantially horizontal and assumed to be rectangular. The upper plate 6 is fixedly linked to four rods 7, two of which are not shown, of the mold suspension, descending vertically, and each comprising at their lower end a rotary horizontal cleat 8, for supporting the mold carrier plate 9 of the mold 2; each cleat 8 being retractable between an open position of the frame 1 and a closed or gripped position under the underside 10 of the mold carrier plate 9 of the mold 2. The blind sand mold 2 is centered on the mold carrier plate 9 and clamped between said plate 9 and the upper clamping plate 11 by means of a double-acting clamping cylinder 12, the head 13 of which pointing downwards is linked, free in rotation, by a ball joint 14, to the clamping plate 11 of the mold 2. The body 17 of the jack 12 is linked to the plate 6. The rotation allowed by the ball 14 makes it possible to use a mold, the upper face of which, represented in dashed dashed lines, is in an inclined plane with respect to the plane from the underside. The lower face of the upper plate 11 being larger or of the same dimension as the upper face of the mold 2.

Au poste de coulée, le moule 2 est appliqué sur la face supérieure d'un dispositif intermédiaire d'usure 15.At the casting station, the mold 2 is applied to the upper face of an intermediate wear device 15.

Le bâti 1 est déplacé en translation par le moyen de transfert 4. Le moyen de transfert 4 porte un organe de préhension et de suspension du bâti qui comporte un vérin à double effet 18 de suspension du plateau supérieur 6 du bâti 1. Le vérin 18 est dirigé vers le bas et sa tête 19 porte le bâti 1.The frame 1 is moved in translation by the transfer means 4. The transfer means 4 carries a member for gripping and suspending the frame which comprises a double-acting cylinder 18 for suspending the upper plate 6 of the frame 1. The cylinder 18 is directed downwards and its head 19 carries the frame 1.

Pour préparer le positionnement, le moule 2 arrive par un moyen de convoyage à l'intérieur du bâti 2, les taquets étant en position ouverte.To prepare the positioning, the mold 2 arrives by a conveying means inside the frame 2, the cleats being in the open position.

On ramène les taquets 8 en position de prise. Le moule ne peut plus sortir du bâti 2. Les taquets sont réglés de façon à ce que leur face d'appui et la partie inférieure du plateau porte moule 9 soient maintenant dans le même plan horizontal. Le puits de coulée 3 du moule 2 s'ouvrant vers le bas débouche sur le vide.The tabs 8 are returned to the gripping position. The mold can no longer leave the frame 2. The tabs are adjusted so that their bearing face and the lower part of the mold carrier plate 9 are now in the same horizontal plane. The pouring well 3 of the mold 2 opening downwards leads to the vacuum.

Ensuite, le vérin de serrage 12 presse le moule 2 et le lie au bâti par serrage, le moule 2 n'ayant pas été déplacé par rapport au bâti 1.Then, the clamping cylinder 12 presses the mold 2 and binds it to the frame by clamping, the mold 2 not having been moved relative to the frame 1.

Puis, le moyen de transfert en translation 4 place le bâti 1 contenant le moule 2 au-dessus de la goulotte d'alimentation 16.Then, the translational transfer means 4 places the frame 1 containing the mold 2 above the feed chute 16.

Ensuite le vérin 18 descend le bâti 1 de façon à mettre le moule 2 en position de coulée.Then the jack 18 lowers the frame 1 so as to put the mold 2 in the casting position.

Pendant toute la période de temps dans laquelle le moule 2 est maintenu en position de coulée, afin d'éviter que ledit moule 2 ne soit soulevé dans le bâti, ce qui provoquerait des fuites de métal liquide, le vérin de serrage 12 exerce une pression dirigée vers le bas, supérieure à la pression fournie par le(s) vérin(s) de suspension 18 pour le positionnement et le maintien du moule 2 sur le dispositif intermédiaire d'usure 15.During the entire period of time in which the mold 2 is kept in the casting position, in order to prevent said mold 2 from being lifted in the frame, which would cause leaks of liquid metal, the clamping cylinder 12 exerts pressure directed downwards, greater than the pressure supplied by the suspension cylinder (s) 18 for positioning and holding the mold 2 on the intermediate wear device 15.

Après la coulée, les vérins 12 et 18 étant à double effet, toutes les opérations ci-dessus sont effectuées dans l'ordre inverse.After casting, the cylinders 12 and 18 are double-acting, all the above operations are carried out in reverse order.

Puis, un autre moule arrive dans le bâti 1 pour la coulée suivante. La hauteur du deuxième moule peut être différente de celle du premier, la course du vérin 12 s'adaptant à la hauteur du moule.Then, another mold arrives in the frame 1 for the next casting. The height of the second mold may be different from that of the first, the stroke of the jack 12 adapting to the height of the mold.
