Abstract
The utility model discloses an extruding die for a reinforced type composite flat cable. The extruding die comprises a die core and a die sleeve, wherein the die core is nested in the die sleeve; a tapered hole and a plurality of open pores are formed in two ends of the die core respectively; the outer wall of the die core is a tapered surface; the tapered hole is communicated with the plurality of the open pores respectively; an arc transition surface is formed between the tapered hole and the plurality of the open pores; an included angle between an axis of the tapered hole and the inner wall of the tapered hole is 30 degrees; a horn-mouth-shaped hole matched with the outer wall of the die core is formed in one end of the die sleeve; a waist-shaped hole is formed in the other end of the die sleeve; the end surface of the die sleeve adopts a convex arc structure; the horn-mouth-shaped hole is communicated with the waist-shaped hole; and an arc transition surface is formed between the horn-mouth-shaped hole and the waist-shaped hole. According to the extruding die, a scorched material cannot be produced, extruding is smooth, and a molten material can flow out smoothly, an extruded protection sleeve is uniform in thickness; and the end surface of a discharge port of the die sleeve adopts the convex arc structure, so that the forming compression time of the die is prolonged to restrain force expansion in the middle, and a non-flat phenomenon is avoided.
Description
Technical field
The utility model relates to the extrusion die field, specifically is a kind of extrusion die of reinforced compound flat cable.
Background technology
Along with the development of industries such as China's port and pier, power plant, steel mill, mine, introduced a large amount of comprehensive mechanical equipment, its power supply adopts collection power, communication mostly, is controlled in the flat type cable of one or various specific (special) requirements.Flat type sheath soft cable is for mobile frequent, need the occasion of crooked towing, but the mould of flat cable is designed to the technical barrier that flat cable is produced.
Common round cable, because its circular configuration, the pressure of circular die orifice circumferentially is being evenly distributed, so its sheath is not prone to above-mentioned quality problems.Flat type cable is quite different, because the level of its die orifice and being uneven in length of vertical direction cause the inhomogeneous of extrusion pressure, this technological problems does not solve, and the sheath quality just is difficult to control.
The used flat cable sheath of existing domestic most of cable factories is extruded die sleeve, and the shortcoming of its structure is the materials flow inequality, and because having the dead angle on the die sleeve inwall place circumference, the stream material remains in a standstill at this place easily and causes burnt material.
According to the rubber-plastics material melt flow characteristics, runner is more level and smooth, when extruding discharging more easy, if core rod adopts the conventional squash type geometry of figure, gel quantity on platypelloid type die orifice place's level and the vertical direction is not waited, be difficult to guarantee to extrude the uniformity of thickness.
When extruding the rubber flat cable, because rubber has the viscoelastic body characteristic, make the middle pressure maximum of die sleeve mouth pancake, flow is just fast especially, owing to expand, makes product cause " flat type is not flat " phenomenon of bulging.
The utility model content
The purpose of this utility model provides a kind of extrusion die of reinforced compound flat cable, the problem of the technological equipment that the flat cable that solve power, communication, is controlled to be one is produced at common extruder.
The technical solution of the utility model is as follows:
A kind of extrusion die of reinforced compound flat cable, include core rod and die sleeve, described core rod is nested in the die sleeve, it is characterized in that: the two ends of described core rod are respectively equipped with bellmouth and a plurality of perforate, the outer wall of core rod is taper surface, described bellmouth connects with a plurality of perforates respectively, has arc transiting surface between bellmouth and a plurality of perforate, and the axis of bellmouth and the angle of its inwall are 30 °; One end of described die sleeve is provided with the toroidal hole that the outer wall with core rod is complementary, the other end of die sleeve is provided with mounting hole, and its end face is the evagination arcuate structure, and described toroidal hole and mounting hole connect, and has arc transiting surface between toroidal hole and the mounting hole.
The extrusion die of described a kind of reinforced compound flat cable is characterized in that: have ring-shaped step on the end outer wall of described die sleeve.
The beneficial effects of the utility model:
1, a plurality of perforates and the mounting hole that pass for steel wire respectively of core rod of the present utility model and die sleeve realized the manufacturing with wire reinforced flat cable;
2, the utility model is according to the mobile characteristics of plastics molten condition, when the axis of bellmouth and the angle of its inwall were 30 °, plastics were mobile best by mould, can not produce burnt material, extrude smoothly, guaranteed the fluency that melted material flows out from angle;
3, have between arc transiting surface and toroidal hole and the mounting hole between the utility model bellmouth and a plurality of perforate and have arc transiting surface respectively, guaranteed the mobile smoothness in the plastics extrusion, make that the jacket thickness of extruding is even;
4, the runner of the utility model die sleeve is smooth, does not have the dead angle, when being used with core rod, can form stable extrusion pressure, and the gel quantity at any position is impartial relatively in the runner, has played the smooth closely knit effect of extruding layer;
5, when extruding the rubber flat cable, this is because rubber has the viscoelastic body characteristic, make the middle pressure maximum of die sleeve mouth pancake, flow is just fast especially, owing to expand, makes product cause " flat type is not flat " phenomenon of bulging, the end face evagination arcuate structure of the utility model die sleeve discharging opening, prolong its shaping pressurized time with tension in the middle of suppressing, solved " flat type is not flat " phenomenon, guaranteed shape requirement.

The specific embodiment
Referring to accompanying drawing, a kind of extrusion die of reinforced compound flat cable, include core rod 1 and die sleeve 2, core rod 1 is nested in the die sleeve 2, the two ends of core rod 1 are respectively equipped with bellmouth 3 and a plurality of perforate 4, and the outer wall of core rod 1 is taper surface, and bellmouth 3 connects with a plurality of perforates 4 respectively, have arc transiting surface 5 between bellmouth 3 and a plurality of perforate 4, the axis of bellmouth 3 and the angle of its inwall are 30 °; One end of die sleeve 2 is provided with the toroidal hole 6 that the outer wall with core rod 1 is complementary, the other end of die sleeve 2 is provided with mounting hole 7, and its end face is evagination arcuate structure 8, and toroidal hole 6 connects with mounting hole 7, has arc transiting surface 9 between toroidal hole 6 and the mounting hole 7.
In the utility model, has ring-shaped step 10 on the end outer wall of die sleeve 2.
