Injection moulding device comprises a nozzle with support to inject matters, a cavity bottom with main cavity having pressure pad plated against the support to tighten the nozzle and the cavity and a delivery pipes

摘要

The support (4) extends along the main cavity (22) to form a plasticizing cylinder, in which nozzle (1) partially extends, with its end opposite to the injection point. The plasticizing cylinder has to co-operate with a wall of the main cavity (22) to ensure centering cavity, where the cylinder has a chamfer (44) of connection between the end surface and the cylindrical portion.
