Cooled injection core for an integrated injection blow mold machine

A removable cooled core for a plastic injection mold assembly, the removable cooled core forming at least a portion of a mold in which an article can be molded, the removable cooled core comprising

• an outer wall and a distal end wall defining the exterior surface of the removable cooled core,
• a first water channel within the core for circulating water through the core to cool hot plastic forming said article contiguous to the outer wall,
• a first water inlet and a first water outlet connected to the first water channel for circulating water through the first water channel,
• an inner conduit extending through the cooled core to an opening in the distal end wall,
• a poppet valve including a head mating with the opening in the distal end wall for controlling introduction of air between the molded article and the removable cooled core distal end wall, and
• means for cooling the poppet valve head, the cooling means comprising a poppet cooling conduit connected to a second water inlet for circulating water between the second water inlet and a second water outlet to cool plastic forming said article adjacent to the poppet valve head.

• a first water channel within the core for circulating water through the core to cool hot plastic forming said article contiguous to the outer wall, the first water channel including an inner wall situated within the mold core outer wall, and a plurality of water directing elements situated between the inner wall and the mold core wall to impart a spiral flow pattern to water flowing through the first water channel,
• a first water inlet and a first water outlet connected to the first water channel for circulating water through the first water channel,
• an inner conduit extending through the cooled core to an opening in the distal end wall,
• a poppet valve including a head mating with the opening in the distal end wall for controlling introduction of air between the molded article and the removable cooled core distal end wall, and a stem connected to said head, the stem being situated within said inner conduit, and
• means for cooling the poppet valve head, the cooling means comprising a poppet cooling conduit connected to a second water inlet for circulating water between the second water inlet and a second water outlet, the poppet cooling conduit extending through the valve stem to the head to cool plastic forming said article adjacent to the poppet valve head.
