    摘要: A method of filling a core cavity (2) is provided wherein the entire core cavity is uniformly filled with highly compacted sand for molding the core without the need of providing many ventholes. The method is characterized in that sand for molding the core is drawn into the core cavity (2) to preparatorily fill it, and after that the thus prepared sand is repeatedly and sequentially compacted by impulsively pressurizing the sand, starting from the sand at its innermost positions.

    摘要: A core box vent useful in core making, comprises a porous cylinder of sintered ceramic materials, the pores of such cylinder being less than will allow intrusion of the grain size of sand to be introduced to the core box.
    A method of making cores comprises the steps of:

    (a) forming matable core box sections (25,26) with blow tubes (27) permitting introduction of an air fluidized sand mixture into the interior of the mating core box sections, and further forming one or more ceramic core box vents (20) in the exhaust side (30) of the mated core box sections to permit egress of air used to fluidize the sand mixture, said vents (20) having a labyrinth of passages (21) or pores smaller in diameter than that which allows intrusion of the grain size of said sand mixture;
    (b) blowing through said blow tubes (27) into said mated core box sections a sand and resin mixture that is prevented from exiting through said vents (20), said resin being curable to polyurethane by chemical reaction;
    (c) forcing a catalyst curing gas through said blow tubes (27) to cure said sand and resin mixture again without migration of any of said sand through said vents (20); and
    (d) purging said core box sections (25,26) with air introduced through said blow tubes (27) and exiting from said core sand mixture via said vents (20).

    摘要: Dans un procédé pour fabriquer des pièces moulées, à l'intérieur desquelles est introduit un milieu, notamment pour fabriquer des boîtes à noyau pour le tirage des noyaux, des orifices d'aération pourvus d'ajutages sont prévus dans l'espace de moulage. Lors du moulage de la pièce ou d'un noyau disposé dans celle-ci, notamment de la boîte à noyau, on utilise au moins un insert dont la forme correspond à l'ajutage, et on enlève cet insert après le moulage de la boîte à noyau et on le remplace par l'ajutage.
