The invention is related to equipment for injection moulding of parts from plastics, that consists of injection moulding machine and suited to it mould, where the mould consists of at least three parts that are movable one related to another and that lie closely one beside another in position of operation along the partitioning planes going through cavities and being orientated perpendicularly to moving direction of the parts and parallel one to another, wherein each partitioning plane goes through at least one cavity and wherein at least one channel is provided in the mould for injection of melted plastic, which ends at one side in the cavities and at the other side at the place of inlet on the upper side of the mould, which in position of operation is attached to the injection moulding machine. A task is solved in the invention, to build the above mentioned equipment in a way so that to enable usage of tandem-type injection mould providing for encrease of productivity of the machine, together with an ordinary injection moulding machine. The task accordingly to the invention is solved in a way that a channel is provided in the mould which extends from the place of inlet to the first partitioning plane and further to the second partitioning plane, and branch channels go from the channel to the cavities. A fixing device is attached to the parts of the mould that is switchable between two positions, by means of which in the first position only middle part of the mould and its front part comprising place of inlet are fixed together, and in the second position only the middle part and the rear part of the mould are fixed together.
