Apparatus for blow moulding articles

摘要

Each blowing station of the plant has a valve(44) for controling compressed air flow and a connector(41) for connecting the valve with the inside of a preform to be molded. The valve(44) is held in a carrier(45) adjacent to the connector. A baseplate(43) with air flow channels holds the valve carrier and both can be joined or parted parallel to the parting plane of the blowing mold. The valve may be a high pressure valve operated at either 40 bar or 4-20 bar or can be a venting valve. Mounting of the baseplate is on a blowing station support(42). The baseplate comprises a support plate(47) and valve holding plate(46) which are sealed relative to each other. Valves may be arranged on both sides of the connector(41) and two valves can be arranged one above the other. Bores in the support plate are linked to connecting channels in the station support. Bores in the valve holding plate are linked to the valves and the connector. Air flow channels between the support plate and valve holding plate may be formed in either plate surface.
