The utility model relates to an automatic extruder die head of easy change of pressure regulating especially relates to one kind and can change die head pressure automatically, the multi -purpose double screw extruder die head of one end. Its design part mainly includes: the filter corresponds board (14), the filter corresponds mechanism in -line (11), footstep bearing (13), rotating blade (12), the filter corresponds the oil path of mechanism (16) constitution and filter matched with die head internal pressure adjustment mechanism's drivetrain parts, sealing washer (15) are advanced sealedly to this mechanism, spring (8) provide the pretightning force of case (4), the motion of on -off control case (4) through in -line (7) and oil path (10) fluid, seal flow passage control mechanism end cover (9), the material finally flows through die orifice screw (17). Can can also reach directly multi -purpose effect through changing die orifice screw (17) through the automatic pressure value that regulate and control the aircraft nose of the inside structural change of aircraft nose (1) through above -mentioned structure.
