Description

Extrusion die for preventing wire core from sliding

Technical Field

The utility model relates to an extrusion die, specifically speaking are prevent gliding extrusion die of sinle silk.

Background

The flat cable sheath with a metal wire is usually formed by a corresponding extrusion die during production and forming. The traditional mold core of the extrusion mold for the cable sheath is designed into an integral oblate shape, as shown in figure 1, the mold core comprises a mold sleeve 1, a mold core mold opening 2, a mold sleeve mold opening 3 and a mold core, the integral mold core mold opening is only one, and when the extrusion mold is used for extruding the sheath, the pressure of a wire core is large and uneven, the position is easy to slide, and the phenomena of eccentricity, thickness instability and the like are easy to occur.

Disclosure of Invention

The invention aims to provide an extrusion die for preventing a wire core from sliding.

In order to solve the technical problems, the invention adopts the following technical scheme:

the utility model provides a prevent gliding extrusion die of sinle silk, includes die sleeve and mold core, and the mold core is established in the die sleeve, is equipped with the die sleeve nib in the die sleeve, and the mold core block is in the die sleeve nib, be equipped with two insulation core holes and a metal wire hole on the mold core, the metal wire hole is located the middle zone in two insulation core holes.

The metal wire hole is tangent to the two insulated wire core holes, and a gap is arranged at the position where the metal wire hole is tangent to the two insulated wire core holes and enables the metal wire hole to be communicated with the two insulated wire core holes.

The two insulated wire core holes and the metal wire holes are arranged side by side.

The two insulated wire core holes and the metal wire holes are both circular.

The diameters of the two insulated wire core holes are the same, and the diameter of the metal wire hole is smaller than that of the insulated wire core hole.

A gap is arranged between the metal wire hole and the insulating wire core hole.

The utility model discloses can prevent effectively that the sinle silk from sliding, improve the stability of production efficiency and quality.

Detailed Description

For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

As shown in the accompanying

drawings

2 and 3, the utility model discloses a prevent gliding extrusion die of sinle silk, including die sleeve 1 and mold core 6, mold core 6 is established in die sleeve 1, is equipped with die sleeve die orifice 3 in the die

sleeve

1, and 6 blocks of mold core are in die sleeve die orifice 3, be equipped with two insulating wire core holes 2 and a metal wire hole 4 on the mold core 6, metal wire hole 4 is located the middle zone in two insulating wire core holes 2, and two insulating wire core holes 2 are arranged side by side with metal wire hole 4.

The metal wire hole 4 is tangent to the two insulated wire core holes 2, and a gap 5 is arranged at the position where the metal wire hole 4 is tangent to the two insulated wire core holes 2, so that the metal wire hole is communicated with the two insulated wire core holes, and the gap is usually smaller.

The two insulated wire core holes and the metal wire holes are both circular, and are correspondingly circular according to the shape of the cable, so that the cable has universality.

In addition, two insulation wire core holes and metal wire holes are horizontally arranged with the die sleeve die orifice. Of course, when other specific requirements exist, the device can be arranged in other modes, and flexible change can be performed according to the requirements.

The utility model discloses in, the insulated wire is drawn forth from the insulated wire core hole, and metal wire (ground wire) are drawn forth from the metal wire hole, and it is fixed to utilize respective hole site to carry out position location to corresponding line, and the slip that makes a round trip when can effectually preventing the sinle silk from extruding, moreover, hole site shaping separately ensures that the atress is even, ensures the accuracy at center, improves product quality stability.

Although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that modifications, equivalents, improvements, and the like can be made in the technical solutions of the foregoing embodiments or in some of the technical features of the foregoing embodiments, but those modifications, equivalents, improvements, and the like are all within the spirit and principle of the present invention.
