<p>An injection molding apparatus for hollow parts comprises first and second co-operating dies, each die including a first male die core and a female die recess. One of the dies is rotatable about an axis. In a first angular position of the rotatable die, the male die core of the first die co-operates with the female die recess of the second die and the male die core of the second die co-operates with the female die recess of the first die, to define first and second molds in which half-components may be formed. In a second angular position of the rotatable die, the respective female dies recesses of the first and second dies co-operate to form a third mold in which the half-components may be joined. The apparatus makes use of a single injector differentially controlled for each stage.</p> |
