FIELD: technological processes.
SUBSTANCE: invention relates to hot-forming tooling. Die comprises a holder, in the cavity of which there is a die with a molding cavity. Cage has a top and bottom transverse openings for the coolant, with top, middle and lower ring grooves and with screw grooves. Screw grooves extend with their ends into upper and middle annular grooves. Cavity crosswise openings are open to top and bottom annular grooves. Central annular groove is located below the zone of conjugation of parts of the forming cavity of the matrix, which has inclined channels located in the above zone for cooling agent and longitudinal or inclined grooves on external surface. Said grooves extend in their lower annular groove. Inclined channels of the matrix, at the beginning of which the screw grooves of the cartridge are opened, come out with their ends to the beginning of the longitudinal or inclined grooves. Die has transverse windows extending by their ends into upper annular groove of cartridge and to beginning of upper part of forming cavity.
EFFECT: result is higher die resistance due to more efficient cooling of its surface.
