Mould for producing the injection-moulded plastic part, consisting of a housing upper part or steady rest and mould holder (10''). It consists essentially of an upper (100) and a lower (102) mould half, and forms between them a mould cavity for the injection-moulded plastic part (10''). The two mould halves each have a central part and an outer annular part (104, 106 and 108, 110, respectively), so that in the event of an alteration to the appearance of the dial of the watch only the upper central part (104) need be replaced, while all the remaining parts of the injection mould can stay the same. Likewise, in the event of a change in the design of the steady rest only the upper outer annular part (106) need be exchanged. Ejector pins (112) of the mould and a core (114) for mounting a set-hands arbor are provided. Upon opening of the injection mould, the core (114) is drawn outwards by a mandrel (116) mounted on the upper mould half (100), since it is guided in the lower mould half (102) to be capable of displacement in the longitudinal direction. No discharge opening of the injection mould is represented. <IMAGE> |
