MULTILAYER DISC FAN MOLDING DIE AND METHOD OF MANUFACTURING MULTILAYER DISC FANS USING THE SAME.

摘要

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.
