Specific embodiment
Explanation is further explained to the utility model in the following with reference to the drawings and specific embodiments, but is not limited practical
Novel protection scope.
As shown in Figure 1 to Figure 2, a kind of production plastic cement products extrusion mandrel, mould body 1 and circular tube shaped including canalis spinalis shape
Connect the die body that mould 2 forms, connection mould 2 and mould body 1 are integrally formed, and mould body 1 is equipped with major diameter import and path and exports, path into
The inner wall of mouth is equipped with internal screw thread, and connection mould 2 is located at the major diameter input end of mould body 1, the internal diameter and mould body 1 of the connection mould 2
Major diameter input end internal diameter it is identical, on the inner wall of the mould body 1 close to path outlet end be equipped with tapered slot 3 and cylindrical groove 4,
The surface of cylindrical groove 4 is equipped with screw thread and twist-on has inner wall for the fixed ring 5 on inclined-plane, the inner wall of fixed ring 5 and the inner wall of mould body 1
