Extrusion moulding mould of online small -bore tubular product of biaxial orientation plastics

The utility model discloses an extrusion moulding mould of online small -bore tubular product of biaxial orientation plastics, including managing embryo shaping district, insulated zoon and the two -way district that dilates, pipe embryo shaping district, insulated zoon and the two -way district that dilates connect in proper order. Pipe embryo shaping district is including die body, reposition of redundant personnel awl, mandrel support, the aircraft nose body, bush, coaxial adjusting screw, plug, heater, thermocouple and connecting screw, passageway in plug and the mandrel support is equipped with high temperature resistant adiabatic hose and joint. Axial, radial tensile is carried out to the small -bore tubular product of plastics (the plug diameter is lighter than 20mm) to the invention, improves the physics mechanical properties of plastics tubular product, has improved its intensity and toughness greatly, has improved the axiality of tubular product and the homogeneity of wall thickness degree, and has reduced the consumption and the reduction in production cost of material by a wide margin.
