摘要:
A method and apparatus for equalizing gate pressure of a hot runner nozzle are disclosed. The nozzle includes a nozzle housing defining a primary melt channel, a first nozzle tip having a first secondary melt channel in fluid communication with the primary melt channel, a second nozzle tip having a second secondary melt channel in fluid communication with the primary melt channel, and a valve disposed in the primary melt channel for selectively opening and closing a downstream end of the primary melt channel to control a flow of melt to the first and second secondary melt channels. In some embodiments, the valve is configured to selectively open when a pressure of the melt reaches a threshold peak pressure. In some embodiments, the valve includes a valve stem that cooperates with the primary melt channel to block a flow of melt therefrom until the threshold peak pressure is established.
