FIELD: machine building.
SUBSTANCE: invention can be used in a tooling for hot forging of a forged disc. Cooled matrix comprises lower support and upper shaping parts. Support part has annular grooves arranged on its upper end face with partitions forming common partition, two lateral openings on side surface and blind axial seat. Besides, there is a reduction for the sealing element. Peripheral annular groove is made with longitudinal socket open to second transverse window. Annular grooves are in-series connected to each other by means of oppositely lying depressions of separating walls and partitions. Coolant is fed through second crosswise opening, displaced through lengthwise seat, annular grooves and blind axial seat and led out through crosswise opening communicated with blind axial seat.
EFFECT: result is higher matrix resistance.
