Description

Tire tread extrudes mouth device

Technical field

The utility model relates to the tire production apparatus field, at length is that a kind of production tire tread extrudes mouth device.

Background technology

As everyone knows, all-steel radial tyre enterprise uses the tyre surface semi-finished product of one or both sizing material production plurality of specifications, different structure for adapting to variation, differentiation product demand at present.For guaranteeing that tyre surface each several part size meets design requirement, general tyre surface size according to different size, different structure, the tyre surface pre-die is designed to the shape close with tread structure, and be used with the whole die panel of corresponding specification tyre surface, for this reason, tire enterprise need be processed the demand that a fairly large number of pre-die satisfies different product, make tire enterprise increase hundreds thousand of frock costs, long owing to the pre-die process-cycle simultaneously, restrict the progress of tire enterprise new product development, can not satisfy the requirement of shortening the tire construction cycle.

Summary of the invention

The purpose of this utility model is to overcome tire tread extrusion pre-die need process the more demand that satisfies different product of quantity, cause frock cost height, and the problem of restriction tire new product development progress, the utility model provides a kind of tire tread to extrude mouth device, satisfies the tire tread production requirement of plurality of specifications, different structure.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of tire tread extrudes mouth device, be provided with shape of the mouth as one speaks box, shape of the mouth as one speaks box inside is equipped with pre-die, whole die panel, it is characterized in that: pre-die is monolithic construction, the upper and lower gum outlet that is processed with respectively of pre-die reaches gum outlet down, the place, exit position of gum outlet is provided with whole die panel under last gum outlet reaches, and whole die panel comprises by bolted die panel and the following die panel gone up.

The utility model also can be realized by following measure: be processed with spew groove on the following die panel.

The beneficial effects of the utility model are that tire enterprise can significantly reduce tyre surface pre-die quantity, saves the frock cost, and is conducive to improve the new product development progress, also can change the pre-die number of times because reducing, and reaches the purpose of enhancing productivity.

1. shape of the mouth as one speaks boxes are 2. gone up die panel among the figure, and 3. spew groove 4. descends die panel, 5. descends gum outlet, and 6. pre-die is 7. gone up gum outlet, 8. sizing material interface, 9. opening.

The specific embodiment

As shown in Figure 1, the utility model is provided with shape of the mouth as one speaks box 1, shape of the mouth as one speaks box 1 inside is equipped with pre-die 6, whole die panel, pre-die 6 is monolithic construction, the upper and lower gum outlet 7 that is processed with respectively of pre-die 6 reaches gum outlet 5 down, the place, exit position of gum outlet 5 is provided with whole die panel under last gum outlet 7 reaches, and whole die panel comprises by bolted die panel 2 and the following die panel 4 gone up.Following die panel 4 is processed with the spew groove 3 of difformity, different size, or does not have spew groove 3, satisfies the production of different structure, different size tyre surface by spew groove 3 sizes of adjusting die panel 4 under the whole shape of the mouth as one speaks of tyre surface.

As shown in Figure 2, between last gum outlet 7 and the following gum outlet 5 sizing material interface 8 is arranged, last gum outlet 7 tread mix of flowing through, the following gum outlet 5 tire base sizing material of flowing through.The tread mix of extruding through extruder is by last die panel 2 gum outlets of last gum outlet 7 arrival of pre-die 6 whole die panel shown in Figure 1, tire base sizing material arrives the spew groove 3 of die panel 4 under the whole die panel shown in Figure 1 by the following gum outlet 5 of pre-die 6, tire base sizing material upwards flows then, and with pre-die 6 on after the tread mix that flows out of gum outlet 7 converges, together by last die panel 2 openings of whole die panel, finish extruding of tyre surface.

If produce the tyre surface of version shown in Figure 3, a kind of sizing material then by last die panel 2 openings 9 of the whole shape of the mouth as one speaks of tyre surface shown in Figure 4, is produced the tyre surface of structure shown in Figure 3 by gum outlet 7 on the general pre-die 6 of tyre surface shown in Figure 1.
