Abstract

L'invention a pour objet un dispositif de noyautage pour fonderie par gravité, ledit dispositif de noyautage comportant : - des moyens de constitution des noyaux comprenant des outillages définissant des cavités de moulage, - des moyens d'alimentation en composé(s) pulvérulent(s) desdites cavités par des ouvertures d'alimentation, et - des moyens de séchage des noyaux en cours de constitution dans lesdites cavités par soufflage d'un fluide par des ouvertures de soufflage, tel que les ouvertures de soufflage sont distinctes des ouvertures d'alimentation.

Figure imgaf001
The subject of the invention is a coring device for gravity casting, said coring device comprising: - means for constituting the cores comprising tools defining molding cavities, - supply means for powdery compound (s) ( s) of said cavities by feed openings, and - drying means of the cores being formed in said cavities by blowing a fluid through blow openings, such that the blow openings are distinct from the openings of food.
