FIELD: machine building.

SUBSTANCE: invention can be used for manufacture of elastic support hinges (ESH) of nozzle blocks of solid-propellant rocket engines (SPRE). Die mould for manufacture of reinforced rubber technical goods with layer-by-layer located reinforcement elements and layers of elastomer includes upper and lower semi-moulds, and upper and lower forming rings, as well as fasteners of reinforcement elements. Upper and lower hold-down rings rigidly attached to the corresponding moulding rings are installed opposite fasteners of reinforcement elements. One hold-down ring is equipped with screws screwed into threaded through holes open in that ring against the stop into fasteners of reinforcement elements. Through slots for passage of elastomer to reinforcement elements are made in the other hold-down ring.

EFFECT: number of die moulds of the design as per the described invention has been developed by the enterprise, where high-quality ESH of nozzle blocks with various dimensions are manufactured and the required manufacturability is provided.
