Abstract
The utility model discloses a low smoke and zero halogen cable extrusion die, including mold core (1) and die sleeve (2), during die sleeve (2) were located in mold core (1), mold core (1) and die sleeve (2) centre was equipped with jiao dao (4), die sleeve (2) hold the line than being 0.4. The utility model discloses enabling the cable when passing through the mould, keeping the stability of sinle silk, realize extruding and press equilibrium of forces, disconnected glue can not appear, the material flows unstablely and surface phenomenon such as crude, the cable jacket of the system of crowd is smoothly surperficial, more accords with the technological requirement, can effectively improve the production efficiency of cable product.
Description
Technical field
The utility model relates to Design of Dies field, particularly relates to the extrusion die that a kind of electric wire is produced.
Background technology
Low-smoke halogen-free cable, refer to and be made up of the sizing material of the material of not halogen-containing, not leaded, the contaminated environment such as cadmium, chromium, mercury, the corrosivity of burning gases is little, it also avoid the infringement to other instrument and equipments in building, the characteristic of low halogen, Halogen, cable material is improved with UV resistant and other irradiation behaviour greatly ageing-resistant, thus extends the service life of cable, wide market.But the shaping difficulty of this cable cover(ing) is large, owing to adopting environment-friendly type sizing material, existing plsitive mold is when extruding sheath, easy appearance is broken the faults such as glue, pore and extrusion pressure be unstable, and when causing production, thickness can not meet technological requirement, thus affects production efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of low smoke and zero halogen cable extrusion die, when can make cable by mould, keep the stability of core, realize the balance of extrusion pressure, the phenomenon such as there will not be the unstable and surface of disconnected glue, stream crude, the cable jacket smooth surface extruded, more meets technological requirement, effectively can improve the production efficiency of cable products.
The technical solution of the utility model is as follows: a kind of low smoke and zero halogen cable extrusion die, comprise core rod and die sleeve, core rod is located in die sleeve, Jiao Dao is provided with in the middle of core rod and die sleeve, the line ratio that holds of die sleeve is 0.4, be subject to suitable resistance when cable jacket can be made to extrude, the shaping rear surface of sheath is smooth and tight.
In aforesaid this low smoke and zero halogen cable extrusion die, the sizing ratio of described core rod sizing area is 1.2.
In aforesaid this low smoke and zero halogen cable extrusion die, described core rod outside cone angle is 39 ° ~ 42 °, and when can ensure to produce, jacket thickness meets technological requirement, enhances productivity.
In aforesaid this low smoke and zero halogen cable extrusion die, the wall thickness of the outlet port of described core rod is 0.6mm ~ 0.8mm, thus avoid core rod and formation vortex, mould junction, cause the instability of extrusion pressure, that effectively can improve cable jacket extrudes quality.
In aforesaid this low smoke and zero halogen cable extrusion die, the reach of described core rod is 12mm ~ 15mm, can ensure that core rod is combined firmly with cross-head.
Compared with prior art, when the utility model can make cable by mould, keep the stability of core, realize the balance of extrusion pressure, the phenomenon such as there will not be the unstable and surface of disconnected glue, stream crude, the cable jacket smooth surface extruded, more meets technological requirement, effectively can improve the production efficiency of cable products.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-core rod, 2-die sleeve, 3-outlet port, 4-Jiao Dao, 5-screw thread.
