Universal rotating base for moulds for multi-injection of plastics has fixed bodies (3, 4) mounted on the mobile plate (2) of the injection machine and a central splined shaft (5) able to rotate and move axially. One end of the shaft (5) is mounted in a central bearing (6) itself mounted on the front face of the fixed body (3, 4). That end has a head (18) onto which is demountably fitted a rotating element (7) being part of the multi-injection mould (7-14). The rotating element (7) can be part of a bi-injection mould with dual cavities (9, 10) on a rotating injector. The base is universal accepting all types of mould made for rotation.
