ABSTRACT:
The coupling means of the assembly comprise machine-side coupling parts, which are movable by means of hydraulic cylinders into coupling engagement with the mold-side coupling parts secured to the sections of the injection mold. As a result, the movable mold section is provided with a coupling for connecting the mold to supply lines for a performance of auxiliary operations in both mold sections and the stationary mold section is provided with a coupling for conducting a fluid for the temperature control of both mold sections. Because the coupling for the temperature control and the coupling for any auxiliary operations to be performed in the injection mold are separated from each other, the expenditure involved in the coupling equipment can be adapted to the current requirements of a potential buyer and nevertheless it is possible to effect a temperature control of the injection mold also when it is outside the clamping region of the injection molding machine.
