Method and apparatus for blow molding hollow plastic containers |
摘要 |
A mold system for blow molding hollow plastic containers includes an extruder for providing a hollow tube of plastic material having a longitudinal axis. Three mold segments include at least two mold segments that are movable against the third mold segment, in directions perpendicular to the tube axis, between a closed position in which the mold segments form a hollow mold cavity in which the tube is captured and an open position spaced from the tube axis. A blow pin is disposed on one of the mold segments to pierce the tube in the closed position of the mold segments. One of the mold segments may be a mold core movably mounted on a second of the mold segments, and cylinders are mounted on the second mold segment for moving the mold core between an extended position and a retracted position with respect to the second mold segment. The blow pin may be movably mounted on the mold core.
