Abstract
The utility model relates to a kind of ultrahigh molecular weight polyethylene tubing mould internal diameter shaping cover, comprise extrusion die, described extrusion die comprises mould pipe and the mouth mould of inclination, it is characterized in that, mold core is provided with in mouth mould, mold core is provided with internal diameter shaping cover and extending port mould, external diameter and the pipe internal diameter of described internal diameter shaping cover match, and described extrusion die also comprises the linear interflow strengthening segment be arranged between spreader and mould pipe.The utility model solves the bending of ultrahigh molecular weight polyethylene tubing and elliptic problem, and the tubing intensity of preparation is good.
Description
Technical field
The utility model relates to a kind of ultrahigh molecular weight polyethylene tubing mould internal diameter shaping cover.
Background technology
Current ultrahigh molecular weight polyethylene tubing due to speed of production slower, its type of cooling generally all designs at mould itself, thus tubing can not get cooling fully and sizing, leave mould mouth when naturally cooling, can the phenomenons such as bending, oval be produced, cause bad appearance quality to product.
Summary of the invention
The utility model provides a kind of ultrahigh molecular weight polyethylene tubing mould internal diameter shaping cover, which solves the bending of ultrahigh molecular weight polyethylene tubing and elliptic problem.
The technical scheme that the utility model specifically adopts is:
A kind of ultrahigh molecular weight polyethylene tubing mould internal diameter shaping cover, comprise extrusion die, described extrusion die comprises mould pipe and the mouth mould of inclination, it is characterized in that, mold core is provided with in mouth mould, mold core is provided with internal diameter shaping cover and extending port mould, external diameter and the pipe internal diameter of described internal diameter shaping cover match.
Further, described extrusion die also comprises the linear interflow strengthening segment be arranged between spreader and mould pipe.
Compared with prior art, the utility model has the advantages that:
1) after mold diversion shuttle, add interflow strengthening segment, tube material is first straight operation after spreader, then compresses reducing, is more conducive to eliminate mould interflow line, improves tubing intensity;
2) when tubing is after mouthful mould is left in mold cools down sizing, mold core adds one section of sizing section consistent with pipe internal diameter, and after tubing leaves mouthful mould, temperature has dropped to about 50 degree relatively, continue to run in internal diameter sizing section, tubing runs in this section will drop to about 30 degree, and internal diameter is fully shaped by the section of sizing, thus tubing comparatively circle, and through the cooling of this section, tubing primary crystallization terminates substantially, and tubing is comparatively straight, no longer bending.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of ultrahigh molecular weight polyethylene tubing mould internal diameter shaping cover, described mould comprises spreader 1 and extrusion die, described extrusion die comprises linear interflow strengthening segment 2, the mould pipe 3 tilted and mouth mould 4, and described interflow strengthening segment 2 is arranged between spreader 1 and mould pipe 3; Be provided with mold core 6 in mouth mould 4, mold core 6 is provided with internal diameter shaping cover 5 and extending port mould 4, external diameter and the pipe internal diameter of described internal diameter shaping cover 5 match.
