ABSTRACT:
The present invention has a multi-station molding system formed having a upper housing segment and a lower housing segment which are interconnected by a plurality of elongate guide and support rails and a central support column. The upper and lower housing segments may optionally be formed of pie-shaped segments which are symmetrically spaced in an abutted, side-by-side orientation. The segments can be fabricated and/or mechanically linked as desired to provide two, three, four, five, six, or more work stations within the system. A plurality of independently movable platens are mounted between the upper and lower housing segments and are each affixed to a cylinder lift to reciprocate the movable platens toward and away from the upper housing segment. Each of the stations are provided with a mold, the male portion of which is typically affixed to the rotatable mold carrier that is attached to the upper housing segment and the female portion of which is typically affixed to the vertically movable platen. The upper housing segment is provided with a rotary table which rotates about the central column such that the plural injection molding units may be positioned at each one or selected ones of the stations to effect the injection molding process with selected molds. Each of the injection units may be provided with a different thermoplastic material and/or different color as desired.
