Abstract

An arrangement is provided in an injection mould with a hot-runner system, comprising a stationary mould part (4) and a movable mould part (6) including mould cavities (8), runner blocks (10), tab sleeves (12), at least one needle valve (2) movable between two end positions, and an operating means (16, 24). The novel features of the inventive arrangement reside in that the needle valve (2) has at least one bore extended in the axial direction for providing a tubular valve, that a core (22) is at least partly supported in said bore for movement relative to the needle valve (2), and that a portion of the core (22) extends into the mould cavity (8) to form a dead hole or a through hole in the finished moulded article.
