ABSTRACT:
Access to mold halves disposed on and between opposed stationary and movable platens of a molding machine is facilitated by releasing and at least partially retracting, from the zone between the platens, at least one of a plurality of tie rods extending therebetween. A tie rod is at least partially removed by (1) slidingly translating the movable platen along the tie rods toward the stationary platen, (2) releasing one tie rod from connection with the stationary platen and connecting it to the movable platen, and then (3) slidingly translating the movable platen away from the stationary platen along tie rods remaining connected thereto, to at least partially retract the released tie rod from between the stationary and movable platens.
