Device for sieving, mixing and filtering of hot thermoplastics metals

摘要

The assembly is fitted into a tool with heated channels, esp. in the bore (38) of an injection nozzle head (36). It consists of a pedestal (2), with a centrally bored blind hole (16) with passages (6,7,8,9,10) running radially to its peripheral outer surface (44). Opposite the outer end face of the pedestal (2) there are round pillars (21,22,23,24,25,26), held parallel to the central axis (42). All adjacent pillars form line contact, broken by openings (32). Their far ends are accepted by a retaining ring (3) which has a central passage.
