A distribution plate (10) for a mould for the injection moulding of plastic materials, comprising a plurality of distribution elements (21, 22, 23), arranged adjacently but separate from one another by a certain distance (17, D), and defining internally a distribution network (14) consisting of a plurality of hot flow channels (14-1, 14-2, 14-3, etc.); and one or more tubular couplings (18) to connect the hot flow channel sections (14-1, 14-5) which extend through two adjacent distribution elements (21 - 22, 21-23), wherein the distribution plate (10) also comprises sealing means (24) consisting of at least two Belleville springs (26, 27) which are mounted on the outside of each tubular connecting coupling (18) and accommodated in the space (17, D) that separates the two adjacent distribution elements (21, 22) in the connection zones of the hot flow channels. Further a Belleville spring comprising a ring-shaped pressure plane and produced in a grinding operation is provided. |
