ABSTRACT:
The apparatus includes a first chamber disposed about the mold cavity and defined by a top, a bottom, and walls extending between the top and bottom at the inner and outer peripheries of the first chamber. A liquid coolant is supplied under pressure to the first chamber through an inlet. A step is formed adjacent one of the corners between the top and bottom .and the inner peripheral wall of the first chamber, a circumferential groove is formed in the outer peripheral wall of the step, and an elastomeric sealing ring is sealingly engaged with the mouth of the groove to define a second chamber in the groove. Meanwhile, the shoulder of the step is spaced apart from the other corner of the first chamber, and a series of holes is formed in the shoulder to permit the coolant to pass into the second chamber at a reduced pressure. A passage then discharges the reduced pressure coolant onto a body of metal emerging from the discharge end opening of the cavity.
