An apparatus for instruction in the techniques of blow molding includes an air cylinder actuated ram parison extruder secured atop a frame carrying a low mass mold set. The mold set includes two thin wall mold segments mounted for reciprocal travel toward a closed position at a molding station. Each mold segment is adjustably secured to one of a pair of webbed, heat dissipating jaws with each jaw being adjustably mounted to a worm-driven carriage. Mold segment set up is accomplished by loosely mounting the jaws to their respective carriages and the mold segments to their jaws; the jaws are brought toward one another to close and align the mold segments. With the segments closed and registered, they are then tightened to the jaws and the jaws to the carriages thereby assuring repeated registration of the mold segments during molding cycles.
