Abstract
Dans ce dispositif, une structure de distribution de sable (20) est placée entre une hotte d'alimentation en sable (16) et un châssis (48) comportant un modèle (70). La structure de distribution de sable comprend deux plaques juxtaposées (82, 84) ayant des ouvertures; ces plaques peuvent être réglées l'une par rapport à l'autre de façon à faire varier la coïncidence de leurs ouvertures (122, 222). Il est possible, en changeant les dimensions et les emplacements des ouvertures dans les plaques, de choisir le débit désiré et/ou de disperser sélectivement le sable sur le modèle.In this device, a sand distribution structure (20) is placed between a sand supply hood (16) and a frame (48) comprising a model (70). The sand distribution structure includes two juxtaposed plates (82, 84) having openings; these plates can be adjusted relative to each other so as to vary the coincidence of their openings (122, 222). It is possible, by changing the dimensions and locations of the openings in the plates, to choose the desired flow rate and / or to selectively disperse the sand on the model.
