Method and apparatus for controlling the cooling of molds for the controlled-pressure
casting of metals |
(57) The invention relates to a method of controlling the cooling of the inner surfaces
of the molds (8-8) used for the pressure-casting of metals, wherein, after the removal
of a casting and the cleaning of said surfaces, the step of detecting the temperatures
of said inner surfaces, is followed by a cooling step carried out by means of water
sprays (4), each one of which cools a portion of said surfaces, so that at a given
moment, after the said second step having been carried out, the entire surface is
at the same optimum temperature to permit the coating or lining thereof, the amount
of water to be sprayed being established automatically by a central electronic unit
(7).
