Abstract
The utility model relates to a diagonal vacuum tire mould and belongs to the field of tire moulds. The diagonal vacuum tire mould comprises a two-piece type vulcanizing mould, and is characterized in that an up-down type bead part of the two-piece type vulcanizing mould comprise a middle bead ring, a side bead ring and a mould body; an inclined exhaust line is arranged on one side of the joint surface of the middle bead ring, the side bead ring and the mould body; a circumferential exhaust line is arranged on the other side of the joint surface of the middle bead ring, the side bead ring and the mould body; radial exhaust lines are uniformly distributed on the whole circumference of the circumferential exhaust line; a radial exhaust groove and a circumferential exhaust groove are formed in a side bead ring of an up-down type bead toe part of the two-piece type vulcanizing mould; an exhaust hole is formed in the junction of the radial exhaust groove and the circumferential exhaust groove; and the exhaust hole penetrates through the mould body. The diagonal vacuum tire mould is simple in structure and can be used for effectively exhausting air in a bead hole so as to overcome the defects of glue shortage and bubbles generated by the bead toe part in production and prevent the hidden trouble caused by air leakage of a vacuum tire.
Description
Technical field
The utility model relates to the tire field, at length says it is a kind of oblique vacuum tire mould.
Background technology
As everyone knows, it is cope and drag pattern mostly that the oblique vacuum tire vulcanizes employed mould, and this mould has the advantages such as making is relatively simple, durable in use, not yielding; But, for the tire manufacturing enterprise that adopts BOM sulfuration process production cross-ply, the one of main bad of puzzlement produced on-site is the various bubbles of tire lip, because BOM technique must be come filling and vulcanization medium and conduction heat with curing bag, so just produce curing bag and the tire applying compression problem at each position inside, the tire lip position of tire is as the position of curing bag and carcass compression maximum, the problem that produces is because compression is large, fit closely, causing the nest at this position to deposit gas can't in full force and effectly discharge, it is bad to form the rear minute bubbles of tire finished product sulfuration or starved, thereby cause the apparent defective of finished product, and increase the material reprocess and the cost on the manpower.For common tire (tire that the inner tube of a tyre is arranged), bore in the tire heel position of mould to add under steam vent or the rim line and carve the roller line and can effectively address this problem, but for vacuum tyre, this mode can allow vacuum tyre stay the hidden danger of gas leakage, and gas leakage then is the most fatal to vacuum tyre.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of oblique vacuum tire mould, and the gas that tire lip nest can be deposited is discharged effectively, thereby it is bad to improve the tire toe produces in the production bubble, starved, prevents the hidden danger that vacuum tyre leaks air.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of oblique vacuum tire mould, comprise the two-piece type sulfurizing mould, it is characterized in that, the tire lip position of two-piece type sulfurizing mould is by middle tire lip ring, side tire lip ring and die ontology three parts form, middle tire lip ring, composition surface one side of side tire lip ring and die ontology three parts is processed with the exhaust line with gradient, at middle tire lip ring, the opposite side on the composition surface of side tire lip ring and die ontology three parts is processed with a circumferential exhaust line, the uniform radially exhaust line that is processed with on the circle of this circumferential exhaust line, the mo(u)ld top half tire toe position of two-piece type sulfurizing mould, be processed with radially air discharge duct and a circumferential air discharge duct on the side tire lip ring of mo(u)ld bottom half tire toe position, each radially air discharge duct be processed with steam vent with the circumferential intersection of air discharge duct, steam vent runs through die ontology.
The beneficial effects of the utility model are, simple in structure, the gas that tire lip nest can be deposited is discharged effectively, thus improve produce in tire the toe bubble, the starved that produce bad, prevent the hidden danger that vacuum tyre leaks air.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model, also is the schematic diagram of a kind of embodiment.
Fig. 2 is B of the present utility model section enlarged drawing.
Fig. 3 is the A direction partial schematic diagram of the utility model Fig. 1.
1. side tire lip rings among the figure, 2. in tire lip ring, 3. die ontology, 4. steam vent, 5. circumferential air discharge duct, 6. air discharge duct radially, 7. with the exhaust line of gradient, 8. circumferential exhaust line, 9. exhaust line radially.
The specific embodiment
Such as Fig. 1, Fig. 2, shown in Figure 3, the utility model the utility model is upper cross-ply two-piece type sulfurizing mould, mo(u)ld bottom half tire lip position, mould is divided into side tire lip ring 1, middle tire lip ring 2 and die ontology 3 three parts, at side tire lip ring 1, middle tire lip ring 2 is carved the exhaust line 7 of beating with gradient with die ontology 3 composition surfaces one side, the length general control is below 4 mm, length with control tire finished product glue hair, but in order to allow the smooth and easy discharge of gas energy, then at side tire lip ring 1, the opposite side on middle tire lip ring 2 and die ontology 3 composition surfaces, circumferential exhaust line 8 of elder generation's car, carve at this circumferential exhaust line 8 again and beat radially exhaust line 9, circle uniform some (quantity can be decided according to the mould size).
Moreover, for further improving the degassing function of sulfurizing mould tire lip toe, on tire toe side tire lip ring 1 down, uniform radially air discharge duct 6 and the circumferential air discharge duct 5 of carving the certain depth some that add of circle, and at each radially air discharge duct 6 and the circumferentially intersection of air discharge duct 5, bore the steam vent 4 of certain pore size, steam vent 4 runs through die ontology 3 again, the gas that tire lip nest can be deposited is discharged effectively, thereby improves the tire toe produces in the production bubble, starved phenomenon.
