to simplify the cleaning of hot runner feed lines , and consequently to reduce the downtimes , an injection mold with at least one central feed line and a number of plates arranged one above the other is proposed . the injection mold has at least one hot runner feed line with one or more branching points , at which the hot runner feed line changes direction and / or is divided . in each plate , the hot runner feed line runs in a straight line from the upper surface of a plate to the lower surface of the plate . these hot runner feed lines run straight and at an angle within the plate . at least on one side , the hot runner feed lines open out into exchangeable inserts . for cleaning the injection mold , the exchangeable inserts can be removed from the plates and cleaned separately , while the straight - running hot runner feed lines can be mechanically cleaned in a conventional way .
