Abstract

PURPOSE:To simplify control of flow rates and correction of ununiform thickness, etc. at the start of an operation by a method wherein a die body in the pipe-extruder is divided into two parts in a longitudinal direction of a resin passage and flow control pins are inserted detachably from the outside of the die body to the resin passage. CONSTITUTION:The die body 1 in the pipe-extruder for extrusion-molding a synthetic resin pipe is manufactured by segmental dies composed of an upper surface 1a and a lower surface 1b. A spindle form core 4 fixed on the lower surface 1b is provided in the resin passage 3 to form tubular slits 3', 3'' having openings on the front side and several flow control pins 9 are inserted freely movably at symmetrical positions pinching the resin passage from the outside of the die body 1 into the resin passage 3. At the start of an extruding operation the core 4 is fixed on the lower surface 1b of the die body 1 so that correct tubular slits 3' can be provided, segmental dies are assembled always to provide correct tubular slits 3' and when flow rates and/or ununiform resin thickness must be controlled, they can be controlled easily by the adjustment of adjust pins 9, a movable land 5.
