Device comprising a mold for manufacturing hollow bodies. Processes are known for the manufacture by casting of hollow bodies with or without a bottom, for example consisting in casting liquid metal into a mold or a shell giving the external shape of the hollow body to be obtained. , this mold or this shell being filled as if it were a question of obtaining a solid body with no interior void, then leaving the mold or the shell thus filled in the casting position for the time necessary to obtain by solidification the desired wall thickness for the body to be manufactured, and finally to empty by any means the non-solidified metal, so as to form the central cavity of the hollow body to be obtained.
Lorsque 1a vidange du metal encore li quide a lieu par basculement du moule, an a propose d'imprimer au moule au moins Pen dant la vidange un mouvement de rotation, de maniere ä communiquer au metal en fusion un mouvement helicoidal pour eviter un enle- vem,ent local de metwl päteux et obtenir ainsi des corps creux ä, parois d'epaisseur uniforme. Pour realiser ce mouvement de rotation du moule, en mAme temps que son mouvement de renversement pour la vidange du metal li quide, il est necessaire cependant de disposer d'appareils relativement . compliques. When the emptying of the still liquid metal takes place by tilting the mould, it has been proposed to impart to the mould, at least during the emptying, a rotational movement, so as to impart to the molten metal a helicoidal movement to avoid removal. vem, ent local pasty metwl and thus obtain hollow bodies with walls of uniform thickness. To achieve this rotational movement of the mold, at the same time as its overturning movement for the emptying of the liquid metal, it is however necessary to have relatively apparatus. complicated.
La presente invention a pour objet un dis- positif comportant un moule pour fabriquer des corps creux en coulant du metal liquide dans ce moule, en ne daissant se solidifier qu'une Partie de ce metal au contact dune partie au moins de la surface interne du moule, puis en basculant ce dernier pour en eliminer 1e metas encore liquide. The subject of the present invention is a device comprising a mold for manufacturing hollow bodies by pouring liquid metal into this mold, only allowing part of this metal to solidify in contact with at least part of the internal surface of the mould, then tilting the latter to eliminate the still liquid metas.
Ce dispositif est caracterise en ce que la paroi dudit moule presente une region dann laquelle son epaisseur est plus Brande que celle du reste de 1a paroi, afin que la cha- leur du metal liquide puisse s'ecouler plus rapidement ä travers cette region plus epaisse de la paroi et qu'ainsi l'epaisseur du metal se solidifiant soit plus Brande dans sa Partie ad- jacente ä cette region, dans 1e but qu'en fai- sant basculer 1e moule du cöte presentant la plus Brande epaisseur de paroi pour eliminer 1e mptal encore liquide celui-ei- reste 1e plus This device is characterized in that the wall of said mold has a region in which its thickness is greater than that of the rest of the wall, so that the heat of the liquid metal can flow more rapidly through this thicker region. of the wall and so that the thickness of the solidifying metal is greater in its part adjacent to this region, with the aim that by tilting the mold to the side having the greater wall thickness to eliminate the 1st metal still liquid this one remains the 1st most
longtemps en eontact avec la Partie solidifiee de plus grande epaisseur et n'enleve en s'eeou iant de meta-1 päteux qu'ä rette Partie et quo Fon puisse ainsi obtenir un Corps creux pre sentant des parois d'epaisseur uniforme. a long time in contact with the solidified Part of greater thickness and does not remove pasty meta-1 by flowing except from this Part and so that it is possible to obtain a Hollow Body having walls of uniform thickness.
Comme an 1e remarquera, los moyens pre vus dann,ce dispositif pour obtenir des Corps 'a parois d'epaisseur uniforme sont beancoup plus simples quo dann los appa.reils utilises jusqu'ä ce jour. As one will notice, the means provided in this device for obtaining Bodies having walls of uniform thickness are much simpler than in the devices used to date.
Le dispositif pourrait etre agence de fa @on quo Fon puisse fabriquer avee lui des eorps c.reux de forme exterieure cy lindrique, ovofde, cubique, prismatique, par exemple; 1a ca.vite pouvant, par exemple, eire ouverte ou non. The device could be arranged so as to quo Fon can manufacture with it c.reux bodies of cylindrical external shape, egg-shaped, cubic, prismatic, for example; 1a ca.vite can, for example, eire open or not.
Le dessin annexe represente, 5, Eitre d'exemple, Je moule dune forme d'exeeution du dispositif selon Finvention. The accompanying drawing represents, 5, Eitre example, I mold dune form of execution of the device according to the invention.
La. fig. 1 est une coupe selon Faxe de ce moule qui est de forme eylindrique et permet de fabriquer des Corps creux presentant im fond; La fig. `? est une vue en plan de ee inoule. et la fig. 3 est une vue en elevation clutlit moule montrant Je renflement de sa paroi. Le moule represente est de forme eylindi-i que et presente une paroi laterale 1() et <B>Im</B> fond 11. Cette paroi laterale 10 c.omporte une i-6oion dann larluelle son epaisseur est. plus grande quo cel.le du teste de la paroi, rette region de la paroi <B>1.0</B> presenta.nt exterieure ment un renflement 12 de forme tolle quo ses sections perpendiculaires ä laxe du moule out la forme de Croissants, Ces eroissants allaut en diminuant de grandeur du bord su p6rieur 13 du moule jusqu'ä sa base l4. Ce renflement est venu de fabrication avee 1e teste du moule. The. fig. 1 is a section according to Faxe of this mold which is eylindrical in shape and makes it possible to manufacture hollow bodies having a bottom; fig. `? is a plan view of ee inoule. and fig. 3 is an elevational view of the mold showing the bulge in its wall. The mold represented is of eylindi-i shape and has a side wall 1 () and <B>Im</B> bottom 11. This side wall 10 includes an i-6oion dann larluelle its thickness is. greater than that of the test of the wall, this region of the wall <B>1.0</B> presents on the outside a bulge 12 of the shape tolle quo its sections perpendicular to the axis of the mold or the shape of Croissants, These eroissants decrease in size from the upper edge 13 of the mold to its base l4. This bulge came from manufacture with the first mold test.
0n pourrait se servir pour faire basculer ce moule pour 1e vider, d'un mecanisine de n'importe quel type connu, agissant nur 1e moule, par exemple de maniere ä 1-e faire pi voter selon un axe perpendiculaire au plan de coupe de la, fig. 1, c'est-ä-dir,de maniere quo 1e plan de pivotement passe par la Partie la plus epaisse du renflement 12. 0n could be used to tilt this mold to empty it, a mechanism of any known type, acting on the first mold, for example so as to 1-e vote along an axis perpendicular to the cutting plane of the, fig. 1, i.e., so that the pivot plane passes through the thickest part of the bulge 12.
Lorsque Fon desire fabriquer tin Corps creux, an remplit 1e moule 10, 11 de metal en fusion, an laisse se solidifier une Partie 15 de ce in6tul, 1a Partie se solidifiant en Premier etant celle en contact avec la. surfacE interne du moule, puis an basoule 1e moule selon Faxe indique ei-dessus, pour en vider 1e metal non eneore solidifie. Comme an 1e coniprendra. lors de 1a vidange du metal en core liquide, celui-ei roste en contact avec 1e metal solidifie, et 1a duree de ce contact n'est pas kt meme pour tonten los Parties du inetal solidifie. Les Parties restant 1e plus longtemps en contact avec 1e metal liquide sont rechauffees et refondent partiellement. Si donc avant de basculer 1e moule, 1'epais seur de metal soliclifie est la, meme nur tont 1e pourtour interne du moule. a-pres versement du metal eneore liquide, eette epaisseur a.ura subi urie diniinution Jans certaines de ses par t;t#. qui Sera 1a. plus forte it Fendroit oh Fef fet inecanique de 1a, coulee du lneta.l liquide pourrait diminuer Fepaisseur de 1a paroi du Corps ereux. Pour compenser cet enlevemetit pa,r fusion dune Partie de la paroi du corp.4 erelix. la Partie de paroi plus epaissepermet im econlement plus rapide de la chaleur ä tra vers eette Partie qu'it travers 1e teste de la. haroi (In inoitle, e, clui a pour consequenee quo Fepaisseur du meta.l se solidifia.ut devient plus graude dann sa. pa.rtie adjacente au ren flement 12. 011 s'arrange pour quo lots du basculeinent du inoule pour la vidange du me tal encore liquide, Ces Parties plus epaisses de la paroi du eorps creux soient celles qui restent en. contaet 1e plus longtemps avec 1e inetal en fusion de faVon quo finalement 1e Corps ereux aura. la. meme epaisseur nur tout son pourtour. When Fon desires to manufacture tin hollow body, year fills the first mold 10, 11 of molten metal, year leaves to solidify a Part 15 of this in6tul, 1a Part solidifying in First being that in contact with. internal surface of the mold, then year basoule the first mold according to Faxe indicated above, to empty the first metal not yet solidified. As year 1e will understand. during the emptying of the liquid core metal, the latter remains in contact with the solidified metal, and the duration of this contact is not kt even for all parts of the solidified metal. The parts remaining the longest in contact with the liquid metal are reheated and partially remelt. If, therefore, before tipping the mold, the thickened metal is there, even nur tont the first internal periphery of the mold. after pouring the still liquid metal, this thickness will have undergone a reduction in some of its t;t#. which will be 1a. strongest at the place where the mechanical effect of the a, flow of the liquid lneta.l could decrease the thickness of the wall of the erous body. To compensate for this enlevemetit pa, r fusion of a Part of the wall of the corp.4 erelix. the thicker wall portion allows for faster heat dissipation through this portion than through the test piece. haroi (In inoitle, e, it has the consequence that the thickness of the meta.l solidifies.ut becomes greater in its. of the still liquid metal, These thicker parts of the wall of the hollow body are those which remain in contact the longest with the molten metal so that finally the erous body will have the same thickness all around.
Le dispositif dont 1e moule est represente au dessin Petit eire eoniplete par d'autres dis positions permettant de faire varier dune ma niere definitive Fepaisseur des parois du Corps creux quo Fon desire obtenir. Ces autres dis positions peuvent etre, par exemple, l'adjonc tion Tun anneau refroidissant ä. 1'exterieur an da.ns 1a paroi du moule, Fangmenta.tion de la. conduction de clialeur du fond du moule en constituant ce fand ä 1'aide d'un m.etal tres conducteur, 1'isolation de certaines Parties du moule en vue d'obtenir dans 1e Corps creux termine, aux endroits correspondant ä Ces Par ties, des parois tres minces, voire maure inexistantes, 1'echauffement de certaines par- fies du moule, par des moyens electriques ou chimiques (capsule alumino-thermique), par exemple. The device whose first mold is represented in the drawing Petit eire eoniplete by other said positions allowing to vary in my last definitive thickness of the walls of the hollow body quo Fon wishes to obtain. These other provisions can be, for example, the addition of a cooling ring ä. 1'exterieur year da.ns 1a wall of the mold, Fangmenta.tion of the. conduction of heat from the bottom of the mold by constituting this fand with the aid of a highly conductive metal, the insulation of certain parts of the mold with a view to obtaining in the finished hollow body, at the places corresponding to these parts , very thin or even non-existent walls, the heating of certain parts of the mould, by electrical or chemical means (alumino-thermal capsule), for example.
Pour augmenter .la vitesse d'ecoulement de la chaleur ä @certains endroits du moule, la paroi de celui-ei peut präsenter sofft sur sa sur- face interieure, sofft exterieurement, des ondu- lations augmentant la surface de contact du metal en fusion avec le moule ou respective- ment augmentant le pouvoir de radiation du moule. To increase the rate of heat flow at certain places in the mould, the wall of the latter may present sofft on its interior surface, sofft on the exterior, corrugations increasing the contact surface of the molten metal. with the mold or respectively increasing the radiation power of the mold.
