Definitions

  • the pocket 1, fixed has an upper cover 5 tightly fixed to its side walls and locked by appropriate means (not shown).
  • a pouring nozzle 6 passes through an orifice 7 formed in the cover 5.
  • This nozzle 6 comprises a tubular lower part 8 whose outside diameter corresponds to the diameter of the orifice 7 and an upper part 9, of generally frustoconical shape, which s' presses tightly on the periphery of the orifice 7 by its large flat base 10.
  • a seal 11 formed by an asbestos bead is housed in a groove formed in the base 10 of the nozzle.
  • the frame 3 comprises posts 17 provided at their base with wheels 18 carried by two rails 19.
  • the posts 17 are joined at their upper end by a ceiling 20 carrying a jack 21 directed downwards and whose piston rod 22 carries, articulated at its lower end, a support plate 23.
  • the mold 4 is a solid multi-stage blind mold, for example with three stages, as shown in FIG. 2. It is made of sand and comprises a vertical pouring well 28, of circular section roughly equal to that of the supply tube 12. This well is open at its base, which has a housing 29 having a tapered flared shape combined with that of nozzle 6. It extends up to a certain distance from the upper end face of the mold.
