FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy. Proposed device comprises metal mould composed by heat pipe with heating and cooling areas and insert core. Metal mould walls have cylindrical bores for fitting of tubular electrical heaters therein in amount n = 3-8. Mould cooling area is ribbed. Thermocouples in cooling and heating areas are connected to automatic cutoff system.
EFFECT: higher density and uniformity of metal structure in moulded tread.
