  • Injection Moulding Of Plastics Or The Like (AREA)

Abstract

The invention relates to the plastics processing, namely to processes and nozzles of the plants for injection molding of articles, and can be used for manufacturing plastic articles with surface differing in structure and/or color.The process for injection molding of plastic articles includes the operations of separate plastication and dosing of the mouldable material of different types/color, injection of doses of mouldable material into the shaping cavity through the nozzle with at least two gate channels for separate feeding of material doses to the outlet hole of the nozzle. Injection of material doses, according to the first variant, is carried out concomitantly from all gate channels of the nozzle, filling the entire shaping cavity with mixed materials (into the outlet hole of the nozzle and the gate channel of the shape nearby its inlet hole). According to the second variant, injection of material doses is carried out in series, carrying out the filling of the shaping cavity by portions, beginning from the portion nearby the inlet hole of the shape. Then there follows cooling and solidification of the plastic material, as well as extraction of the finished article.The nozzle of the plant for injection molding of plastic articles contains a body, wherein there are made a central rectilinear gate channel and at least a concentric annular gate channel. Into the body there is placed an annular partition with outlet holes, forming together with the front wall of the body, wherein it is made the inlet hole of the central channel, a chamber. Into the lateral wall of the body there is made the inlet of the chamber. The end portions of the central and/or concentric channels, coming to the outlet hole of the nozzle, are made conic. On the body it is fixed a mouthpiece communicating with the outlets of the gate channels by means of the outlet hole of the nozzle.
