description The utility model relates to a special mould for manufacturing a high-performance and low-cost composite heat insulation pipe, belonging to the field of manufacturing of pipelines for conveying fluids. The mould is characterized in that the center of a mould inlet at one end of the mould is coaxial with the center of a mould outlet at the other end of the mould; the distance between the inlet and the outlet is not longer than 1200cm; and the mould is sequentially provided with a ring-shaped sizing sleeve with the length of 20cm at the mould inlet, a ring-shaped sealing vacuum shaping area with the length of 30cm and a ring-shaped inner tube cooling and molding area in an inner cavity of the mould, a foaming material inlet, a foaming material compression area and a foaming composite molding area with the length of 30cm at the periphery of the mould, a heat insulation layer foaming compound area with the length of 15cm, a heat insulation layer molding area with the length of 15cm, and an outer tube extrusion ma
