Abstract
An injection molding method in which a molding material is injected into a cavity formed in a mold to be molded. The mold is driven to resonate so that resonance occurs in the mold at n wavelengths, where n=m/2 and m is a positive integer, and an injection molding apparatus provided with a fixed mold and a movable mold; the movable mold having a cavity in one side thereof, and an ultrasonic vibration feed device being connected to the other side thereof.
Claims4
An injection molding method in which a molding material is injected into a cavity in a mold, the mold having opposite sides comprising a step of resonating the mold so that a resonance wave measured from one opposite side to the other opposite side has n wavelengths, where n=m/2 and m is a positive integer.
