Machine for moulding articles from thermoplastic polymeric materials

摘要

A machine comprises a plastication arrangement communicating, via passages, with a rotor having injection cylinders on the periphery thereof for feeding therefrom melt into moulds which are arranged in a closed conveyor extending around the rotor. Parts of the moulds having gate passages are arranged in another conveyor which also extends around the rotor and a rotor removing gates from the gate passages. The machine also comprises a rotor for removing finished articles which co-operates with the conveyor carrying the moulds. The conveyors move synchronously and, as they move together around the rotor having the injection cylinders, the injection cylinders are coupled to the moulds, and melt is injected into the moulds. After the conveyors leave the rotor in which melt is injected, they move along different paths to co-operate with the rotors removing gates from the gate passages and finished articles from the moulds.
