Abstract (en)

[origin: WO2016193458A1] The invention relates to a hot runner feed system for a diecasting mould, wherein the feed system comprises a manifold-and-feed block construction with an inlet-side feed inflow opening (1), at least one first and one second outlet-side feed outlet opening (2, 3), which open out into a mould parting plane between a fixed mould half and a movable mould half of the diecasting mould, and comprises a branching runner structure (5), extending from the feed inflow opening to the feed outlet openings. According to the invention, at least in an outlet-side block region comprising the two feed outlet openings, the manifold-and-feed block construction is produced as shortened in a transverse direction parallel to the mould parting plane with respect to a prescribed desired operating extent by an amount (B-b) which is predetermined as a thermal transverse expansion of this block region when it is heated from a room temperature range to a comparatively increased, prescribed operating temperature range. Use for example for the diecasting of nonferrous alloys and molten salts.
