Long nozzle manufacturing mold

The invention discloses a long nozzle manufacturing mold and belongs to the field of metallurgical refractory materials. The long nozzle manufacturing mold comprises a base, a core rod, a rubber jacket, a barrel and a leveling workpiece; the core rod is connected onto the base and sleeved with the barrel, and the leveling workpiece is arranged at the top of the core rod in the barrel; the rubber jacket sleeves the base; the leveling workpiece consists of a bottom triangular support and three metal rods on the top. The long nozzle manufacturing mold aims to solve the problems heat-insulation liners filled during manufacturing of long nozzles always have thick walls and high deviations. Workers do not need to take out the leveling workpiece during filling of the heat-insulation liner materials in manufacturing of long nozzles by changing the leveling workpiece, and the long nozzles manufactured by the mold have uniform wall thickness, are not easy to rupture during use, and accordingly can improve quality of mo
