Abstract
An injection molding apparatus includes: a mold including a fixed mold and a movable mold facing the fixed mold, and that has a cavity defined by the fixed and movable molds and a runner communicating with the cavity; a mold clamping unit moves the movable mold with respect to the fixed mold; an injection unit injects a molding material into the cavity through the runner; a cutting mechanism at the mold includes a cutter projecting to the runner; a drive unit provided on the mold that drives the cutting mechanism; and a control unit controlling the injection unit, the mold clamping unit, and the drive unit. The control unit controls the injection unit to inject the molding material into the cavity, and then controls the drive unit to cause the cutter to project to the runner, thereby cutting the molding material hardened in the runner.
