Claim:
A device for the injection molding of parts made of plastic, comprising: a conventional injection molding machine and a tool dedicated thereto, where said tool contains at least two cavities that correspond to the dimensions of the molded parts to be produced, where the tool comprises at least a front part, a central part and a rear part which are moveable in relation to each other, and which in an operating position are firmly pressed against each other by a pressure force of a pressure generator along at least first and second separation planes that pass through the cavities and are parallel to each other and at right angles to the moving direction of the at least front part, central part and rear part, wherein for use of the conventional injection molding machine a centrally located channel is provided in the front part of the tool which extends from an inlet area to the first separation plane, and continues to the second separation plane within the central part of the tool, the channel having a conical shape within the front part of the tool and a conical shape within the central part of the tool, and partial channels extending from the channel to the at least two cavities, and a lock, moveable between first and second positions, said lock located on the parts of the tool, where, after lifting of the pressure from the pressure generator in the first position, only the central part and the front part of the tool that contains the inlet area of the channel are locked together, and in the second position only the central part and the rear part of the tool are locked together with residual force respectively, wherein moving of the lock between the first and second positions is done by the pressure generator.
