<p>An injection moulding 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 moulds 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 mould in which the half components may be joined. The apparatus makes use of a single injector differentially controlled for each stage.</p> |
