| 摘要 |
An injection-molding half-mold has a base plate (1), a nozzle-carrying plate (2), a cavity-carrying plate (3), and a hot runner (4) to which there are associated a plurality of resistive elements (6) connected externally to a power supply source via at least an electric conductor (9, 19) lead connected to an appropriate external connector. The nozzle-carrying plate (2) can be removed from the hot runner (4) without any need for either the electric conductor lead (9, 19) or the connections of the latter to the resistive elements (6) to be disconnected
