Abstract:
A method for producing molded articles filled with liquid, comprising the steps of:extruding a parison between a pair of elements of a metallic mold;closing said metallic mold by a mold-clamping apparatus driven electrically;holding said parison between said metallic mold;cutting said parison above said metallic mold by a parison-cutting apparatus driven electrically;forming a molded article by expanding said parison;moving said metallic mold holding said molded article which has an opening at a top thereof between a parison-receiving position and a filling position by a mold-feeding apparatus driven electrically;covering over said opening of said molded article between said parison-receiving position and said filling position with clean air flowing out from a clean air box for accommodation of a filling nozzle;inserting said filling nozzle into said molded article by a nozzle-lifting apparatus driven electrically;filling liquid, kept at a fixed temperature and a fixed pressure, into said molded article by a fixed-amount filling solenoid valve;sucking a liquid drop at an end of said filling nozzle by a drop-preventing solenoid valve, after closing said fixed-amount filling solenoid valve;moving up and accommodating said filling nozzle into said clean air box; andsealing the opening of said molded article filled with the liquid.
