Injection-moulding mould configured for being mounted in an injection-moulding apparatus for automated moulding of work pieces from plastics, said injection-moulding mould comprising at least two separate mould parts that are separated by a mould separation face, and wherein at least one mould part 1 is configured with an outer frame 2 in which one or more spaces is/are configured that are open relative to the mould separation face, in which is mounted at least one exchangeable mould insert 3, and wherein the exchangeable mould insert 3 has a mould cavity side that faces towards the mould separation face, which mould cavity side is provided with one or more mould cavities, and wherein, in the mould insert 3, a set of cooling channels 14 is provided and at least two pipe couplings to which there is, for each pipe coupling, configured a cooling pipe 4 being, with its first end, mounted to the pipe coupling and extending therefrom, in its longitudinal direction, from the pipe coupling and out through a channel 8 in the outer frame of the mould part and to its other end. The cooling pipe being secured in the channel in such a manner that it cannot be shifted in the longitudinal direction thereof, it is accomplished that the pipe coupling may be configured such as to occupy only very little space in the mould insert 3.
