- movable means directly supported by one of said plate means,
- molded article retrieval means carried by said movable means,
- said retrieval means being movable relative to said mold halves in synchronism with the stroke thereof,
- a first position of said retrieval means defining a molded article pick up position,
- a second position of said retrieval means defining a molded article release position, and
- means for moving the retrieval means from said second position to said first position before the mold halves have reached a full open position whereby the cycle time of the retrieval means is minimized.
