Apparatus for blow molding plastic articles from a parison
摘要:
In the art of blow molding thermoplastic articles a pair of blow mold halves is closed around a parison. A blowing medium is applied so that the parison is thus blown to a container configuration. In this blowing step very high closing forces are necessary to maintain the mold halves in closed position. The invention provides for a plurality of biased pistons which are actuated by a pressure medium to support the mold halves on a stationary frame.
