Abstract
The utility model provides a kind of orifice wear-resisting pipe damage tubular molding tool of insulated cable sheath extruding machine, including squeezing pipe internal model and crowded external mold, the nozzle bearing line area with cable core in angle is provided at the nozzle of the crowded pipe internal model, the angle of the nozzle bearing line area and cable core is 3 °~8 °, and the position that the crowded pipe internal model is in contact with cable core outer wall is inlaid with wolfram steel and holds line set.The angle of the nozzle bearing line area and cable core is 5 °.The utility model avoids original mold disadvantage when keeping original crowded pipe die to have advantages.It solves former tubular molding tool to be changed to hold the weight of line set receiving cable conductor by wolfram steel by inner mould core nozzle bearing line area receiving cable conductor, and contacts cable conductor with inner mould core nozzle bearing line area.To solve the problems, such as that nozzle is easy to wear in the continuous production process of high temperature, improves the service life of mold.
Description
Technical field
The utility model relates to insulating sheath extruding machine field, specially a kind of nozzle of insulated cable sheath extruding machine is resistance to
Wear tubular molding tool.
Background technique
Currently, used mold has squash type when extruding cable cover(ing) (insulation) of different model specification, squeeze tubular type and
Half squeezes tubular type.Wherein tubular molding tool has disadvantage:
1. tubular molding tool is easily deformed using nozzle at high temperature for a long time；
It is prone to wear, ruptures 2. tubular molding tool nozzle is relatively thin；
3. the mould steel hardness that tubular molding tool uses, finish are lower.
Utility model content
The purpose of this utility model is to provide a kind of orifice wear-resisting pipes of insulated cable sheath extruding machine to damage tubular molding tool.
When keeping original crowded pipe die to have advantages, while original mold disadvantage is avoided.
To reach above-mentioned technical purpose, the technical solution of the utility model includes:
A kind of orifice wear-resisting pipe damage tubular molding tool of insulated cable sheath extruding machine, including squeeze pipe internal model and crowded external mold, institute
State be provided at the nozzle of crowded pipe internal model be in cable core angle nozzle bearing line area, the angle of the nozzle bearing line area and cable core is
3 °~8 °, the position that the crowded pipe internal model is in contact with cable core outer wall is inlaid with wolfram steel and holds line set.
The angle of the nozzle bearing line area and cable core is 5 °.
Compared with prior art, the beneficial effects of the utility model include: when keeping original crowded pipe die to have advantages,
Original mold disadvantage is avoided simultaneously.It solves former tubular molding tool to be changed to by inner mould core nozzle bearing line area receiving cable conductor
Line set is held by wolfram steel and bears the weight of cable conductor, and contacts cable conductor with inner mould core nozzle bearing line area.To solve
Nozzle problem easy to wear, improves the service life of mold in high temperature continuous production process.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Figure label respectively indicates, and 1-squeezes pipe internal model, and 2-squeeze pipe external mold, 3-cable cores, 4-nozzle bearing line areas, 5-tungsten
Steel holds line set.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution:
As shown in Figure 1, a kind of orifice wear-resisting pipe of insulated cable sheath extruding machine damages tubular molding tool, including squeeze pipe internal model 1
With crowded pipe external mold 2, be provided at the nozzle of the crowded pipe internal model 1 be in cable core 3 angle nozzle bearing line area 4, the nozzle holds
The angle of line area 4 and cable core 3 is 3 °~8 °, and the position that the crowded pipe internal model 1 is in contact with 3 outer wall of cable core is inlaid with wolfram steel and holds line
Set 5.
The nozzle bearing line area 4 and the angle of cable core 3 are 5 °.
Before improvement: mold temperature is higher when tubular molding tool squeezes out, and squeezes the relatively thin cable conductor of pipe inner mould core nozzle from crowded pipe
It is pierced by formula mold inner mould core, the weight of cable core is supported by tubular molding tool inner mould core nozzle bearing line area.Cable conductor meeting
Biggish friction is generated with inner mould core nozzle bearing line area, is easy to wear nozzle, rupture causes mold to be scrapped.
After improvement:
In order to improve the service life of mold, inlayed in squeezing pipe inner mould core a wolfram steel hold line set (hardness of wolfram steel and
The finish of finished surface is all better than mould steel).For supporting the weight of cable conductor, and 5 ° inclines is done in nozzle
Angle contacts cable core with nozzle during through inner mould core.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
Claims (2)
