Abstract | A multilayer disc fan molding die capable of manufacturing multilayer precision disc fans at a low cost, and a method of manufacturing multilayer disc fans using the same. A die for molding a resin into a multilayer disc fan is formed so that it consists of inner and outer cores, and at least one of these cores is composed of a plurality of thin blades piled with very narrow clearances maintained thereamong and through holes for resins provided in these blades. The size of each clearance between adjacent blades corresponds to the thickness of each of the disc members of a multilayer disc fan to be molded, and the thickness of each blade the size of each clearance between adjacent disc members of the multilayer disc fan to be molded.
On décrit une filière de moulage pour soufflante à disques multi-couches, qui permet de fabriquer des soufflantes à disques de précision multi-couches à faible coût, ainsi qu'un procédé utilisant cette filière pour fabriquer de telles soufflantes. Cette filière, qui permet de mouler une soufflante à disques multi-couches à partir de résine, est constituée de noyaux internes et externes, l'un d'entre eux au moins étant composé de plusieurs lames minces empilées avec des séparations très étroites entre elles et entre les orifices de passage des résines pratiqués dans ces lames. La dimension de chaque séparation entre des lames adjacentes correspond à l'épaisseur de chacun des disques d'une soufflante à disques multi-couches à mouler et l'épaisseur de chaque lame correspond à la dimension de chacune des séparations prévues entre des disques adjacents de la soufflante à disques multi-couches à mouler. |
