ELECTRICALLY HEATABLE FEED NOZZLE DISPOSED AT THE END OF A HOT RUNNER

摘要

The feed nozzle has a central heater rod (1) and casing sections (2) and (3), the heater rod being connected at the upper end with the casing section (3) and at the lower end through a fork (8) with casing section (2). The casing sections are insulated from each other by means of washers (4) and (5) and define an annular flow channel (15) for the plastic mass that is introduced into the channel at the upper end, and passes out at the lower end through outlets (14) into the feed orifice of an injection mold. The feed nozzle has two tips (11) at the lower end each of which extends into a feed orifice or into the vicinity of a feed orifice of an injection mold. Thus, using the feed nozzle tow injection molds can be filled with plastic simultaneously.
