Abstract
The apparatus includes a carrier plate cooperating with an injection molding machine and having at least two sets of cavities therein for cooling the hollow plastic articles, with the number of cavities corresponding to a multiple of at least two times the number of hollow plastic articles produced in an injection molding cycle. The apparatus also includes means for aligning one set at a time of said carrier plate cavities to juxtapose said set of cavities with the hollow plastic articles formed in an injection molding cycle, and means for transferring said hollow plastic articles to said juxtaposed cavities.
Claims6
An apparatus for producing hollow plastic articles which comprise:
- an injection molding machine including a first mold portion having at least one cavity therein and a second mold portion having at least one elongate core seating in said cavity in mold-closed position to form a first number of hot hollow plastic articles in an injection molding cycle, and means for reciprocating said mold portions form said mold-closed position to a mold-open position forming a gap between said mold portions;
- a carrier plate having at least two sets of cavities therein for cooling said hollow plastic articles, with the number of cavities corresponding to a multiple of at least two times the number of hollow plastic articles produced in an injection molding cycle;
- means for moving the carrier plate into and out of said gap;
- means for aligning one set at a time of said carrier plate cavities to juxtapose said aligned set of cavities with said hollow plastic articles formed in an injection molding cycle;
- and
- means for transferring said hollow plastic articles to said juxtaposed cavities.
