Definitions

  • the ladle is preferably provided with feet 32 and is positioned centrally of a chamber 35 by a plurality of ribs 34 therein.
  • the cover 22 is preferably provided with an insulation pad 36 above the ladle 28 and is seated on an annular resilient sealing gasket 37 affording a substantially air-tight seal between the chamber 35 and the cover 22.
  • the cover is releaseably clamped against the gasket 37 by conventional clamps 38.
  • the distance shown between the plunger seat 44 and the gate seat 46 when the plunger is in open position as illustrated is substantially less than the distance between the plunger seat and the upper surface 48 of the hub section 10 of the mold cavity 8. This arrangement reduces to a minimum the pumping action of the plunger 42 on the molten metal within the mold cavity 8 to minimize any tendency of the molten metal to be forced out of the riser opening 12 as the plunger 42 is actuated from its open position to closed position, whereat the seats 44 and 46 are mated to close the gate 14.
  • riser opening is illustrated in the drawing, preferably a plurality of such riser openings are utilized d], as, for example, three of such openings equidistantly spaced for each other around the longitudinal axis of the plunger 42.
