Abstract:
1. An apparatus for molding an article, comprising: a mold, wherein, when the mold is clamped, a cavity is defined in the mold, and wherein the mold has at least one vent communicated with the cavity; an injecting mechanism for injecting coating material and molding material into the cavity; a decompression mechanism, wherein, after the coating material is injected into the cavity, the decompression mechanism lowers the pressure in the cavity through the vent, thereby forming a predetermined coating on the inner surface of the cavity; an opening-closing mechanism for opening and closing the opening of the vent, wherein the opening-closing mechanism includes switching means and a plug member for blocking the vent, wherein the switching means switches the vent between an open state and a closed state with the plug member; and a controller for controlling the switching means, wherein the controller controls the switching means based on the value of a parameter that represents the pressure in the decompression mechanism.
