An extrusion die for extruding hollow profiles is suggested having a die
head (2), which is connected to a runner part (1) and forms extrusion
channels (3) for shaping a profiled strand (4), and having a runner
chamber (5), which is provided between the die head (2) and the runner
part (1) and runs transversely to the extrusion channels (3), which is
connected around its circumference (8) to an annular channel (7) for
impingement with plastic melt and from which the extrusion channels (3)
of the die head (2) originate. In order to provide advantageous
construction conditions, it is suggested that the runner part (1) have an
inner channel (9) discharging into the runner chamber (5) inside the
annular channel (7) for additional impingement of the runner chamber (5)
with plastic melt.
