The spray head, for the two half-molds of a mold, has an extending arm (1) with a number of channel passages (a-d) for a controlled delivery of the spray medium. A number of spray jets (15) are in groups aligned across the direction (2) of the arm movement, with connections (8,9,10,12) to the passage channels. The jet connection has a number of distribution blocks (3) in succession along the arm movement line. They have channels (4-7) for the medium branching to the side of the passage channels in a given sequence, opening out to both sides (3a,3b). Connection plates (8) are fitted at both sides, which can be changed by 180[deg], each with at least one connecting channel (9,10) so that the jet groups can be linked selectively to one of the passage channels. |
