Valve pin bushing for the hot runner of an injection mold

摘要

To improve the flow symmetry and the molding quality, it is presented a valve pin bushing for the hot runner of an injection mold, including two input channels, each having a geometric axis and through which the material to be injected can enter through an outlet into, and an output channel, which extends along a longitudinal axis up to an output from which the material can exit the valve pin bushing. The portions of the geometric axes, which extend at the outlet are arranged so that on any imaginary plane passing through the longitudinal axis there lies at most one portion.

1. A valve pin bushing for a hot runner of an injection mold, comprising:
an output channel extending along a longitudinal axis up to an exit from which material to be injected can exit the valve pin bushing; two input channels, each having a geometric axis and an outlet through which material to be injected can enter the output channel, each said geometric axis having a portion which extends at a corresponding outlet; and wherein the portions of the geometric axes are arranged so that on any imaginary plane passing through said longitudinal axis there lies at most one of said portions.
