摘要

An injection mold for molding a fan having a shape-adaptive cooling channel is provided to control the rotation unbalance while the fan rotating. An injection mold(10) comprises: a fan(3) made of a hub(5) and a plurality of blades(7) formed in the outer circumference of the hub; a low die(30) having a first cavity(41) for molding the hub and a second cavity(45) for molding the blade; a cooling channel which is adjacent to the first and the second cavity; and a molding unit(37) formed with the high speed metal molding method.
