Abstract:
An injection half-mold, comprising:a base plate; a nozzle-carrying plate; a cavity-carrying plate; a hot runner; a plurality of resistive elements associated with said hot runner, said plurality of resistive elements being externally connected to a power supply source by a respective plurality of electric conductor leads that are connected to an external connector; a plurality of nozzles arranged and supported in said nozzle-carrying plate; and a plurality of resistive elements heating respective said nozzles, said plurality of resistive elements being contained in said nozzle-carrying plate and being connected to a power supply source by a respective plurality of electric conductor leads; wherein at least a portion of said plurality of electric conductor leads of said resistive elements of said nozzle-carrying plate is contained in the body of said nozzle-carrying plate, from which said plurality of electric conductor leads of said resistive elements of said nozzle-carrying plate extend to outside of said nozzle-carrying plate to be connected to a terminal clamp of a power supply connector; and wherein said nozzle-carrying plate is adapted to be removed and displaced away from said hot runner without disconnecting said plurality of electric conductor leads of said resistive elements of said nozzle-carrying plate or connections between said plurality of electric conductor leads and said resistive elements of said nozzle-carrying plate.
