The injection moulding machine, for the prodn. of hollow articles, has a core composed of an inner (11) and outer (12) sleeve, to be moved in a sliding action into a position to fill a wall hollow zone (19) and into a position to close the hollow zone. The inner sleeve (11) can slide axially in relation to the outer sleeve (12). The sleeve (11, 12) enclose a ring vol. (16) at the edge of the wall hollow zone (19) for connection through the relative sleeve sliding movement. A feed channel (15) between the sleeves (11, 12) can be connected to a compressed gas feed jet (14). A piston/cylinder unit (13) at the end of the core sleeves (11, 12) away from the wall hollow zone (19) is subjected to the pressure gas feed from the jet (14) to give an axial sliding movement of the base piston (17) formed as the container base in the inner sleeve (11). <IMAGE> |
