A heating cylinder with a chamber therein is mounted on a base and has a discharge nozzle with an orifice therein, a plunger being movable into the chamber toward the discharge nozzle. A mold holder is supported on the base and has a mold including first and second mold members which jointly provide a mold cavity therebetween. The mold holder is pivotable between a first position in which the mold is held in contact with the discharge nozzle with a sprue in one of the mold members being held in communication with the orifice and a second position in which the mold is located away from the discharge nozzle. There is a means on the base for locking the mold holder in the first position.
