The die comprises a die body, wherein an inner cavity of the die body is respectively provided with a first truncated cone concave hole with a closing-in taper of alpha, a second truncated cone concave hole with a closing-in taper of beta and a cross slot hole from back to front, wherein alpha is larger than beta, the value of alpha is 25-35 degrees, and the value of beta is 5-10 degrees.
Description
Technical Field
The utility model relates to a technical field of cable mould structure specifically is the filling strip and adds the cross of tearing the rope and give as security out the mould.
Background
Present cable is when the preparation, to the part classification type cross filler strip of making in advance as required, increase along with technical requirement, still need set up at the center of cross filler strip and tear the rope, mould is given as security out to original cross, it communicates to the position in cross export groove through the binding off groove that has certain tapering, pull out at the cross center and tear the rope, because cross central point puts the smoothness nature that tears the rope influence and give as security out the sizing material, lead to filling to fill out and give as security out the line footpath unstability, the outward appearance is coarse, production speed can't be opened, there is the breach phenomenon of glue breaking.
Disclosure of Invention
To the above problem, the utility model provides a packing strip adds the cross of tearing the rope and gives as security out the mould, and it adopts big tapering decompression formula, reduces extrusion pressure, increases sizing material shaping distance, improves the smoothness nature of sizing material, guarantees the stability and the appearance quality in line footpath, very big provides production speed.
Fill strip and add the cross of tearing the rope and give as security out the mould, its characterized in that: the die comprises a die body, wherein an inner cavity of the die body is respectively provided with a first truncated cone concave hole with a closing-in taper of alpha, a second truncated cone concave hole with a closing-in taper of beta and a cross slot hole from back to front, wherein alpha is larger than beta, the value of alpha is 25-35 degrees, and the value of beta is 5-10 degrees.
It is further characterized in that: the center of the cross-shaped slotted hole is used for penetrating through the tearing rope, the depth of the concave hole of the first truncated cone is L, the depth of the concave hole of the second truncated cone is H, the depth of the cross-shaped slotted hole is I, L is less than or equal to H, and I is 0.08H-0.15H;
the mold comprises a mold body and is characterized in that the cross-shaped slotted hole is integrated in a cylinder with the thickness of I, an external thread is arranged on the outer annular surface of the cylinder, a cylindrical groove with an internal thread hole is arranged in the inner cavity of the front end of the mold body, the outer annular surface of the cylinder is connected in the cylindrical groove through a thread, and the thickness of the cylindrical groove is I.
After adopting above-mentioned technical scheme, first circular cone platform hole is introduced the back with the material and is followed the slow pan feeding of second circular cone platform hole, and first circular cone platform hole is big tapering structure, and it reduces extrusion pressure fast, later through the longer shaping distance in second circular cone platform hole, and relatively less tapering, has improved the smoothness nature of sizing material, and then guarantees the stability and the appearance quality in line footpath, very big provides production speed.

FIG. 1 is a schematic sectional view of the front view of the present invention;
fig. 2 is a left side view structural schematic diagram of the present invention;
the names corresponding to the sequence numbers in the figure are as follows:
the die comprises a die body 1, a first truncated cone concave hole 2, a second truncated cone concave hole 3, a cross-shaped groove hole 4, a central position 41, a cylinder 5, an external thread 51 and a cylinder groove 6.
Detailed Description
A cross extrusion die for filling strips and tearing ropes is shown in figures 1-2: the mold comprises a mold body 1, wherein an inner cavity of the mold body 1 is respectively provided with a first truncated cone concave hole 2 with a closing-in taper of alpha, a second truncated cone concave hole 3 with a closing-in taper of beta and a cross slotted hole 4 from back to front, wherein alpha is larger than beta, the value of alpha is 25-35 degrees, and the value of beta is 5-10 degrees.
The central position 41 of the cross-shaped slot hole 4 is used for penetrating the tearing rope, the depth of the first truncated cone concave hole 2 is L, the depth of the second truncated cone concave hole 3 is H, the depth of the cross-shaped slot hole 4 is I, L is less than or equal to H, and I is 0.08H-0.15H;
in the specific embodiment: l is H, and I is 0.08H, and the value of alpha is 30, and the value of beta is 5, and cross slotted hole 4 is integrated in thickness is I's cylinder 5, and the outer annular surface of cylinder 5 is provided with external screw thread 51, and the front end inner chamber of mould body 1 is the cylinder groove 6 that has the internal screw hole, and the outer annular surface of cylinder 5 passes through threaded connection in cylinder groove 6, and the thickness of cylinder groove 6 is I.
The working principle is as follows: first circular cone platform hole is introduced the back with the material and is followed the slow pan feeding of second circular cone platform hole, and first circular cone platform hole is big tapering structure, and it reduces extrusion pressure fast, later through the longer shaping distance in second circular cone platform hole, and relatively less tapering, has improved the smoothness nature of sizing material, and then guarantees the stability and the appearance quality in line footpath, very big provides production speed.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
