ABSTRACT:
Apparatus for injection molding plastic articles includes a first mold base, a plurality of mold cavity units fixed to the first mold base, a second mold base, and a plurality of mold core units fixed to the second mold base in alignment with the mold cavity units fixed to the first mold base, the mold bases being reciprocally movable longitudinally with respect to each other, and a stripper plate, situated between the first and second mold bases and movable with respect to the second mold base, carrying a plurality of pairs of secondary mold elements, the secondary mold elements cooperating with the mold cavity-units and mold core units to define the surface of the plastic articles. Additional apparatus for cooling the molded plastic articles includes a support fixed to a surface of the first mold base confronting the second mold base, a plurality of article receiving tubes mounted for movement on the support between a first position aligned with the mold core units and a second position laterally spaced from the first position, a plurality of nozzles are fixed to the second mold base in alignment with the second position and are adapted to direct cooling fluid on plastic articles held by the receiving tubes when the first and second mold bases are positioned adjacent to each other.
