Abstract

An injection molding device comprises a mold-clamping device that operates in both of a mold-closing state in which a mold is closed under predetermined pressure and a micro mold-open state in which the mold is held in a state in which the mold is open from the mold-closing state by a predetermined amount, an injection device that molds a molded product by injecting a molding material into the mold set to the mold-closing state or the micro mold-open state and a controller that changes a stop position of the mold in the micro mold-open state in accordance with a change of a mold-closing position when the mold-closing position of the mold in the mold-closing state is changed.
