Footpath, and the difference between the two is 0.5mm-1mm.The diameter of circular extrusion dish is more than the diameter of cylindrical mould core, it is ensured that the melting in passage
Material is extruded in extrusion by circular extrusion dish side, to ensure that what is be molded extrudes the smooth of inside pipe wall.
As further improvement of the utility model, multiple spiral shells are sequentially provided with along its circumference on the end face of the annular external mold
Pit.Whole mould installion is removed and installed very convenient on the head of extrusion equipment by the screwed hole.
As further improvement of the utility model, the circular extrusion dish and annular extrusion dish use polytetrafluoroethyl-ne
Alkene.The circular extrusion dish of polytetrafluoroethylmaterial material and annular extrusion dish, surface is smooth and does not stick material, makes the inside and outside of extrusion molding pipe
Wall is more smooth.
The beneficial effects of the utility model are：
(1) annular extrusion dish is identical with the thickness of circle extrusion dish and the bottom surface of the two is in same plane, it is ensured that slurry by
Power is uniform, makes wall thickness of extrusion pipe uniform；
(2) internal diameter of annular extrusion dish is less than the internal diameter of annular external mold, it is ensured that fused materials in passage in extrusion by
To the extruding of annular extrusion dish medial surface, with ensure shaping extrusion pipe outer wall it is smooth；
(3) diameter of circular extrusion dish is more than the diameter of cylindrical mould core, it is ensured that fused materials in passage in extrusion by
To the extruding of circular extrusion dish side, to ensure that what is be molded extrudes the smooth of inside pipe wall；
(4) because mould is to be operated in hot environment, the circular easy temperature distortion of extrusion dish, the fixed form of conventional screw makes
Circular extrusion dish is obtained to be very easy to cause to damage during dismounting, thus in the utility model, by circular extrusion dish and post
Shape core rod integrated design, without dismounting during use, adds its service life；
(5) the circular extrusion dish of polytetrafluoroethylmaterial material and annular extrusion dish, surface is smooth and does not stick material, makes extrusion molding
The inside and outside wall of pipe is more smooth.
