Abstract
The utility model discloses a novel extrusion tooling, including the external mold, be equipped with the centre form in the external mold inner chamber, be equipped with the runner between external mold and the centre form, be evacuation passageway in the middle of the centre form cavity, the runner is close to the lower extreme of external mold and centre form and is the footpath section for being, is footpath section below and is external mold corridor section. The utility model has the advantages that: the utility model provides an between crowded pipe and half-pipe give as security out mode, can obtain between crowded pipe and half-pipe adhesive force and half-pipe's complete outward appearance, can save to TPU and low smoke no halogen material sheath and weave outer wrapping process, reduced man-hour, reduced manufacturing cost to the flame retardant property of wire rod has been improved.
Description
Technical Field
The utility model relates to a cable extrusion tooling technical field specifically is a novel extrusion tooling.
Background
At present, three common cable insulation extrusion modes are available: 1: the extrusion type wire drawing machine is very high in pressure, large in wire adhesion and round and neat in appearance; 2: the pipe is extruded, the insulating adhesive force of the wire is small, and the appearance is not round; 3: the semi-extrusion type is smaller than extrusion, but much larger than the extrusion tube type, and has more perfect appearance;
under the following product requirements, the current three extrusion modes cannot meet the requirements: 1: the appearance is good and complete, but the required adhesive force is relatively small, the existing solution is half-pipe partial loosening production, the adhesive force greatly fluctuates along with the fluctuation of the linear speed and the linear diameter in the production process, and the quality problem is easy to occur; 2: the outer quilt with PU or low smoke and no halogen material extruded outside the woven semi-finished product is not easy to peel, and the existing solution is to wrap a layer of paper tape outside the woven semi-finished product, so that the working time is increased and the delivery time is prolonged. Because the paper tape is a flammable material, the flame retardant property of the wire is reduced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel extrusion tooling to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel extrusion tooling, includes the external mold, be equipped with the centre form in the external mold inner chamber, the external mold with be equipped with the runner between the centre form, be the evacuation passageway in the middle of the centre form cavity, the runner is close to the external mold with the lower extreme of centre form is for being the footpath section, it is external mold corridor section to be footpath section below.
Preferably, the outer die is cylindrical and has an integrally molded structure.
Preferably, the inner mold is cylindrically arranged in the outer mold cavity, and the cylindrically inner mold and the inner wall of the outer mold form the flow passage.
Preferably, the pumping hole of the pumping channel is located between the radial section and the outer mold gallery section.
Preferably, the outer die lane section is used for removing the redundant insulating material on the surface of the wire rod.
Advantageous effects
The utility model provides an between crowded pipe and half-pipe give as security out mode, can obtain between crowded pipe and half-pipe adhesive force and half-pipe's complete outward appearance, can save to TPU and low smoke no halogen material sheath and weave outer wrapping process, reduced man-hour, reduced manufacturing cost to the flame retardant property of wire rod has been improved.

Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
Examples
As shown in fig. 1-2, a novel extrusion die comprises an external die 1, an internal die 2 is arranged in an inner cavity of the external die 1, a flow channel 3 is arranged between the external die 1 and the internal die 2, a vacuumizing channel 4 is arranged in the middle of a cavity of the internal die 2, the lower end of the flow channel 3, which is close to the external die 1 and the internal die 2, is a radial section 5, and an external die corridor section 6 is arranged below the radial section 5.
Preferably, the outer mold 1 is cylindrical and has an integrally molded structure.
Preferably, the inner mold 2 is cylindrically disposed in the cavity of the outer mold 1, and the cylindrically shaped inner mold 2 and the inner wall of the outer mold 1 form the flow channel 3.
Preferably, the suction opening of the vacuum channel 4 is located between the radial section 5 and the outer mold lane section 6.
Preferably, the outer mold lane segments 6 are used to remove excess insulation from the wire surface.
The insulation material flow reaches the diameter section through a flow passage between the inner die and the outer die, then the insulation material flow is led to the surface of the semi-finished wire rod in a vacuumizing mode, and the outer surface of the wire rod is coated through a short outer die gallery section;
the insulation is attached to the surface of the semi-finished product in a tube extruding and vacuumizing mode, the inner surface of the semi-finished product is provided with light woven product lines, and the outer surface of the insulation is coated on a very small corridor section to enable the appearance to be complete;
finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the content of the present invention within the protection scope of the present invention.
