Injection control apparatus

摘要

An injection control apparatus includes an injection member; a drive section for injection; an injection-speed detection processing section which detects injection speed; an injection-pressure detection processing section which detects injection pressure; and a drive control processing section which drives the drive section for injection on the basis of the injection speed and the injection pressure to thereby perform pressure control before start of charging of a molding material into a cavity, and speed control after the start of charging of the molding material into the cavity. Since the drive section is driven on the basis of the injection speed and the injection pressure such that pressure control is performed before start of charging of a molding material into a cavity, and speed control is performed thereafter, the pressure of the cavity after the molding material has entered the cavity becomes stable and uniform.
