Wherein, the shunting centrum is conical.
The outer wall of the prepressing part is annularly provided with a prepressing convex body, and the prepressing convex body is used for being in sliding butt joint with the prepressing inclined plane.
The upper end of the shell is provided with a mouth mold, a core mold is arranged in an inner cavity of the mouth mold, and the core mold is connected with the prepressing part.
And the upper end of the mouth mold is fixedly provided with an extrusion intensifying ring.
Wherein, the feeding end is fixedly connected with the shell through a screw.
Wherein, the shell is fixedly connected with the mouth mold through screws.
The utility model has the advantages that:
the utility model discloses novel structure, design benefit utilizes the setting of reposition of redundant personnel centrum for produce the reposition of redundant personnel effect when the sprue pan feeding of feeding section, makes plastics through reposition of redundant personnel centrum when flowing in from the sprue, realizes 360 shunts at no dead angle of plastics, and the material flow homogeneity is good; further, increase the splenium in advance, through the cooperation of the pre-compaction inclined plane of shell, realize the compression to plastics for plastics produce better plastify effect than traditional PE tubular product mould, improve the density of tubular product, and then reach the pressure grade of tubular product more easily, the structure is reliable.
