Abstract

A side gate nozzle is disclosed having a nozzle body, a nozzle tip, and a transfer member. The nozzle body includes a heater, a longitudinally extending nozzle channel, and a bore extending from an outer sidewall of the nozzle body to the nozzle channel. The nozzle tip includes a tip member, a tip channel extending therethrough, and a sealing member surrounding the tip member and receiving the tip member therein. The transfer member seats on a step in a bore in the nozzle body and includes a bearing surface on which the nozzle tip is slidably seated and a transfer channel extending through the transfer member and in fluid communication between the nozzle channel and the tip channel. In operation, thermal expansion of the transfer member along its length exerts a sealing force on the nozzle tip.

Description

technical field [0001] The present invention relates to side-gated injection molding, and more particularly to a side-gated hot runner nozzle having an offset tip assembly. Background technique [0002] Challenges associated with side-gated injection molding include changing tips or tip assemblies without the hassle of disassembling a side-gated hot runner system. Another challenge associated with hot-runner side-gating injection molding includes the gap between the tip and the nozzle body when the tip is aligned with the cavity and the nozzle body is allowed to move or slide relative to the tip during thermal expansion of the nozzle. Forms a fluid tight seal. Contents of the invention [0003] Embodiments herein relate to a side-gated hot runner system, and a side-gated nozzle having a nozzle body, a nozzle tip, and a transfer member. The nozzle body includes a heater, a nozzle channel extending longitudinally into the nozzle body, and an orifice extending from an outer...
