Abstract
The utility model relates to a tire vulcanizing die and belongs to the field of tire dies. The tire vulcanizing die comprises an upper die and a lower die, and is characterized in that a circumferential exhaust grooves are circumferentially processed on the backs of the upper die and the lower die, tire crown exhaust holes and tire side exhaust holes penetrate through the backs of the upper die and the lower die and are communicated with the peripheral exhaust grooves directly or through air ditches, and crisscrossed radial exhaust grooves are processed on the backs of the upper die and the lower die and communicated with the circumferential exhaust grooves. The tire vulcanizing die is simple in structure, and on the premise of keeping matching precision between the die and a machine heating plate constant, a unique exhaust way is designed, the tire die can well transmit heat and exhaust so as to keep smooth operation during practical production.
Description
Technical field
The utility model relates to the tire-mold field, at length says it is a kind of tyre vulcanized mould.
Background technology
As everyone knows, at tyre industry, for guaranteeing the homogeneity of tire, usually require sulfuration board hot plate that very high horizontal plane precision will be arranged, simultaneously, the back side of sulfurizing mould, the i.e. mating surface of sulfurizing mould and hot plate of vulcanizer, also the very high depth of parallelism and surface smoothness to be arranged, in order to avoid cause horizontal plane not good or not with hot plate of vulcanizer hydrous water Pingdu because die surface is uneven.We are when pursuing mould and hot plate precision-fit, but bring another problem, that cooperates better exactly, and that gap between the two is just fewer, in theory, because the outer temperature of tire vulcanization process passes to mould by hot plate, mould and hot plate gap are the smaller the better, but well-known, a very large exhausting problem that difficult point is exactly mould of puzzlement tyre industry, if tire-mold can not be discharged the survival gas in the die cavity well, that certainly will cause outward appearance even the mass defect of tire.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of tyre vulcanized mould, cooperate under the prerequisite of precision with the board hot plate not destroying mould, designed a kind of exhaust mode of uniqueness, tire-mold can be conducted heat well, again well exhaust, with can be in actual production smoothly operation.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of tyre vulcanized mould, be provided with patrix and counterdie, it is characterized in that, the back side of patrix and counterdie circumferentially is processed with circumferential air discharge duct, crown steam vent and sidewall steam vent extend through the back side of patrix and counterdie, crown steam vent and sidewall steam vent directly are connected with circumferential air discharge duct, or be connected with circumferential air discharge duct through connecting channeling, the back side of patrix and counterdie also is processed with criss-cross radially air discharge duct, and radially air discharge duct is connected with circumferential air discharge duct.
The beneficial effects of the utility model are, and are simple in structure, cooperate under the prerequisite of precision with the board hot plate not destroying mould, designed a kind of exhaust mode of uniqueness, tire-mold can be conducted heat well, again well exhaust, with can be in actual production smoothly operation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is section structure schematic diagram of the present utility model.
Fig. 2 is schematic rear view of the present utility model.
1. crown steam vents among the figure, 2. crown steam vent, 3. sidewall steam vent, 4. sidewall steam vent, 5. sidewall steam vent, 6. patrix, 7. counterdie, 8. circumferential air discharge duct, 9. air discharge duct radially 10. connects channeling.
The specific embodiment
As shown in Figure 1, the utility model is provided with patrix 6 and counterdie 7, the back side of patrix 6 and counterdie 7 circumferentially is processed with circumferential air discharge duct 8, circumferentially the quantity of air discharge duct 8 varies in size according to mould, but must follow the minimum number principle, crown steam vent 1, crown steam vent 2 and sidewall steam vent 3, sidewall steam vent 4, sidewall steam vent 5 extends through the back side of patrix 6 and counterdie 7, crown steam vent 1, crown steam vent 2 and sidewall steam vent 3, sidewall steam vent 4, sidewall steam vent 5 directly is connected with circumferential air discharge duct 8, or be connected with circumferential air discharge duct 8 through connecting channeling 10, because mould sidewall steam vent and crown steam vent position generally are relatively-stationary, so, circumferentially the position of air discharge duct 8 to be dropping on sidewall steam vent and crown steam vent to greatest extent wherein as principle, rather than equidistant.Can not drop on sidewall steam vent and crown steam vent in the circumferential air discharge duct 8 for minority, additional processing connects channeling 10, in order to all steam vents all are communicated with.The back side of patrix 6 and counterdie 7 also is processed with criss-cross radially air discharge duct 9, and radially air discharge duct 9 is connected with circumferential air discharge duct 8.Radially air discharge duct 9 connects mould back side four direction, forms the effect that extends in all direction.Wherein, circumferentially air discharge duct 8, radially air discharge duct 9, connect the degree of depth, the width of channeling 10, decide on the mould size, but can not have influence on the heat-transfer effect of mould and hot plate, otherwise, can cause to add the not enough or reduction of sulphur and vulcanize efficient.
