Abstract: The device for moving front and rear ejector disk packets (3a, 3b) of a form tool of an injection molding machine, whose machine side has an ejection unit with an ejection rod subjecting on the disk packets, and a tool side has a compact-socket unit (18) in the disk packet, comprises an internal socket (19), in which a control bolt (20) is arranged. The control bolt cooperates with in radial through holes of breaking unit (17) arranged to the control bolt surrounding the internal socket for transmitting a lifter inlaid by the ejection rod. The device for moving front and rear ejector disk packets (3a, 3b) of a form tool of an injection molding machine, whose machine side has an ejection unit with an ejection rod subjecting on the disk packets, and a tool side has a compact-socket unit (18) in the disk packet, comprises an internal socket (19), in which a control bolt (20) is arranged. The control bolt cooperates with in radial through holes of breaking unit (17) arranged to the control bolt surrounding the internal socket for transmitting a lifter inlaid by the ejection rod. The four breaking units depressively hold a power of subjectable, temporarily, movable support ring during lifting. The socket unit is integrated in the front ejector disk packet and over its breaking unit, a first hub (H1) traversed from the rear ejector disk packet is lockable for the transmission of the forward movement of the ejection rod and the execution of the second hub (H2) traversed from the front disk packet with a holding socket formed at the forward end of the ejection rod. The holding socket is equipped with an interiorly lying compressive-annular groove, in which the breaking unit interferes the socket unit. The partial length of the ends of the ejection rod lying behind the holding socket concentric by a reception socket mounting in the rear disk packet is enclosed in radial through holes intended to engagable and disengagable breaking unit interfered in the initial position before the ejection movement in its assigned profile groove of the ejection rod. The reception socket runs in a guiding socket that is arranged in a rigid mobile machine plate, which allocates a chip area for the tool, and has the annular groove in its head end for the breaking unit. Two radial tortional fall back pins are arranged in the break through of the reception socket additional to the breaking unit. The external mantle of the ejector pole and the internal mantle of the guiding socket are formed with linear slip way for the breaking unit and the fall back pin. The guiding socket ends in the annular groove in the slip way. The bayonet like guiding socket is formed with importable recess arranged to the slip way for the breaking unit and the fall back pin. The breaking element constituted in the reception socket, and the fall back pin are transitioned through turning of the guiding socket on its slip way. The guiding socket allocates a mechanical stop through the rotation for the breaking element. The guiding socket is equipped with a collar, over which a tool centering disk is clamped. The breaking unit is formed as cylindrical control segment.
