Simultaneous filling blow molding apparatus

A simultaneous filling blow molding apparatus, comprising:

• a cross head mounted at an end of an extruder for extruding a parison between a pair of elements of a metallic mold;
• a filling nozzle lifting apparatus lifting a filling nozzle provided in parallel to said cross head;
• a clean air box for accommodating said filling nozzle, means for maintaining the clean air box at a positive pressure;
• a metallic mold feeding apparatus for moving a mold clamping apparatus for opening and closing said metallic mold between a parison receiving position and a filling position;
• a parison cutting apparatus for cutting the parison above said metallic mold;
• and
• a liquid filling apparatus connected to said filling nozzle, comprising a liquid pressure feeding system for controlling the liquid to a fixed temperature and a fixed pressure and a liquid filling system provided with a fixed amount filling solenoid valve and a drop prevent solenoid valve in series for filling the liquid into a molded article;
• wherein said drop prevent solenoid valve includes a flexible bellows attached to said passage and a solenoid core communicating with said bellows, said solenoid core configured to deform said bellows when said solenoid valve is energized;
• wherein said mold clamping apparatus, metallic mold feeding apparatus, filling nozzle lifting apparatus and parison cutting apparatus are electrically driven.
