BLOW-MOULDING PLASTICS

摘要

The novel blow molding unit has mold sections movable toward and away from each other between open and closed positions. A motion-imparting arrangement is coupled with the mold sections for moving them between these positions. A clamping arrangement is located upwardly of the points where the motion-imparting arrangement is coupled with the mold sections and serves to bias the mold sections towards one another either when they are in the closed position or just before they reach the same.
