Oriented injection blow molded container production

An apparatus for producing injection blow molded biaxially oriented plastic articles from plastic parisons comprising:

• a. a frame member;
• b. a transport table mounted to said frame member for rotational movement about and reciprocally along the central axis of said transport table;
• c. a table power means associated with said transport table for effecting said rotational and reciprocal movements;
• d. at least one transversally extending hollow core rod fixedly mounted on said table, said rod having a longitudinally extending hollow portion and said rod having first sealing means at its distal end;
• e. an elongated stretch pin movably mounted in said hollow portion and said stretch pin having,
• i. at its distal end second sealing means for cooperation with said first sealing means to achieve a seal between said first and second sealing means,
• ii. first locking means in mounted relationship with the proximate end of said stretch pin, and
• iii. first engagement moving means associated with said stretch pin whereby movement of said first engagement moving means causes movement of said stretch pin in said hollow portion;
• f. a second locking means mounted to said transport table for cooperation with said first locking means to lock said stretch pin from movement when said stretch pin is in the position within said hollow portion to achieve said seal between the said first and second sealing means;
• g. a second engagement moving means movably mounted to said frame member for engagement with said first engagement moving means when said transport table is in its lowered position at the blow molding station of (h);
• h. a power means for moving said second engagement moving means when it is in said engagement with said first engagement moving means whereby said movement of said stretch pin in said hollow portion is effected, said seal is broken and the distal end of said stretch pin is moved a distance sufficient to cause axial stretch of said plastic parison carried by said core rod;
• i. unlocking means mounted to said frame member for unlocking said lock between said first and second locking means when said transport table is in its lowered position at the blow molding station of (h);
• j. an injection molding station adjacent said transport table for receipt of said hollow core rod so that said parison can be injection formed on said hollow core rod;
• and
• k. a blow molding station for blow forming said article from said injection formed parison while said parison is on said hollow core rod, said blow molding station being located adjacent said second engagement moving means and said unlocking means.
