Abstract

Inventia se refera la o duza cu autoînchidere si indexare pentru prelucrarea maselor plastice prin injectie, care împiedica scurgerea topiturii de material plastic din cilindrul de plastifiere în timpul lucrului. Duza este alcatuita dintr-un corp filetat, un plunjer si un capac, plunjerul având niste canale longitudinale în care sunt presate niste bile prin intermediul unor arcuri reglate cu ajutorul unor suruburi de reglare, realizându-se astfel fixarea pozitiei dorite a duzei, plunjerul având niste canale longitudinale care fac posibila trecerea curentului de material, pozitia de lucru obtinându-se prin rotirea cu ajutorul unei chei fixe a capacului duzei, oprirea curentului de material efectuându-se prin contactul a doua suprafete conice.The invention relates to a self-closing and indexing nozzle for plastic injection molding, which prevents plastic material from flowing out of the plasticizing cylinder during work. The nozzle is formed by a threaded body, a plunger and a cap, the plunger having some longitudinal channels in which some balls are pressed by means of adjustable springs by means of adjusting screws, thus achieving the desired position of the nozzle, the plunger having some longitudinal channels which allow the passage of the material stream, the working position being obtained by the rotation of the nozzle cap by means of a fixed key, the material flow stopping by contacting two conical surfaces.
