Definitions

  • Another object of this invention is to provide a novel gating arrangement, for simultaneously casting a plurality of metal articles, which'prevents the formation of solidified runners.
  • FIGURE 1 is a fragmentary side elevational view, partially in cross-section, of a gating arrangement constructed in accordance with the teachings of this invention
  • FIGURE 2 is a fragmentary cross-sectional view taken substantially on the plane of line 22 of FIG- URE l and looking in the direction of the arrows;
  • FIGURE 3 is a bottom plan view ofthe arrangement as shown in FIGURE 1.
  • FIG- URES l and 2 illustrate a mold assemblylil comprised of left and right mold sections 12 and 14 and left and right mold flask sections 16 and iii secured to a gating assembly 20.
  • Gate body 34 is proivded with a generally invertedtruncated pyramidal recess 40 for the reception therein of a mating refractory flow dividing insert 42 which is provided with an inlet orifice 44 at its lower end and outlet orifices 46 and 48 at its upper end (also see FIGURE 3).
  • a refractory cut-off slide 50 provided with orifices 52 and 54 which at times complete communication between mold cavities 56, 58 and outlet orifices 46, 48, respectively, is slidably retained between mold as'sem biy it and gate body 34.
  • spacer rails or blocks 60 and 62 are provided on opposite sides thereof. Additional shim material, not shown, may of course be employed. Spacer rails 60 and 62 may be formed so as to also insure proper lateral location of slide 50 with respect to the outlet orifices 46, 48 and branch conduits 64, 66.
  • a recess 63 formed in the lower portion of gate body 34 is adapted to receive therein, in mating relationship, a pouring tube '70 of a suitable pressure pouring ladle assembly 72.
  • the mold assembly 10 is preferably comprised of abutting mold sections 12 and 14, forming a parting line 74, which are capable of being moved away from each other thereby affording ready access to solidified castings within cavities 56 and 5s.
  • each of the mold sections and cooperating mold flask sections can be moved outwardly to positions illustrated generally at 16' and 1'8.
  • the operation of the invention is briefly as follows.
  • the mold assembly 10, in its closed position, and gating assembly 20 are positioned atop pouring tube 76 and slide 50 is moved until orifices 5'2 and 54 complete communication between cavities 56, 5 8 and branch conduits 64, 66, respectively.
  • Ladle 72 is then pressurized causing the molten metal contained therein to flow upwardly through tube 7% branch conduits 64, 66, orifices 52, 54 and into mold cavities 56, 58.
  • the pouring of molten metal continues until the respective mold cavities are filled at which time slide 56 is again moved to a position .whereat the previously established communication through orifices 52 and 54 is terminated.
  • the pressure within ladle '72 is then reduced thereby allowing the molten metal within branch conduits 64 and 66 to drain back into ladle 72. 1
  • the entire mold and gate assembly may then be removed from the pouring tube to asuitable location whereatsolidification of the cast metal can occur. After a sufficient length of time, screws 26 may be loosened and mold sections 12 and 14 opened so as to remove the solidified cast articles. 7 a
