Abstract

Inventia se refera la un dispozitiv de injectie-suflare prevazut pe ambele parti ale camerei de formare prin injectie, orientata în directia de închidere, cu cîte o camera de formare prin suflare, cu cîte o camera de formare prin suflare, amplasata sub un unghi de 90 degree , capul de suport fiind prevazut cu doua miezuri de suflare formînd pereche, putînd fi pivotat printr-o miscare alternativa, cu un unghi de 90 degree , în jurul unei axe perpendiculare pe directia de închidere, în fiecare pozitie finala acapului de suport unul din miezurile de suflare gasindu-se în camera de formare prin injectie, iar celalalt miez de suflare gasindu-se în una din cele doua camere de suflare, iar la rotirea fiecarui miez de suflare din pozitia de suflare în pozitia deinjectie este deplasata în directia axiala a miezului de suflare o placa de desprindere cu ajutorul unei role de ghidare aplicata pe profilul de ghidare al unei placi de ghidare.The invention relates to an injection-blowing device provided on both sides of the injection molding chamber, oriented in the direction of closure, by means of a blow molding chamber, with a blow molding chamber located at an angle of 90 degrees, the support head being provided with two winding pairs forming a pair, being pivoted by an alternating motion with an angle of 90 degrees, about an axis perpendicular to the closure direction, in each end position of the support spindle one the blowing cores being found in the injection molding chamber and the other blowing core being located in one of the two blowing chambers, and upon the rotation of each blowing core from the blowing position in the injecting position it is moved in the axial direction of the blowing core a detach plate by means of a guide roller applied to the guiding profile of a guide plate.
