Abstract
The invention discloses a preheating device for a tire vulcanizing mold, and belongs to the technical field of tire vulcanizing equipment. The preheating device for the tire vulcanizing mold comprises an upper mold body and a lower mold body which are arranged in a steam room of the vulcanizing equipment. During mold closing, a tire cavity is formed between the upper mold body and the lower mold body; small holes which are communicated with the steam room and the tire cavity are formed on the upper mold body and the lower mold body, and a capsule device is arranged in the tire cavity; an external temperature medium channel which is communicated with the steam room is formed on the vulcanizing equipment; an internal temperature medium channel is formed on the capsule device; and a capsule expansion channel controlled by a valve is formed between the external temperature medium channel and the internal temperature medium channel. Therefore, the technical problem that the capsule is easily damaged during preheating the mold in the large or giant tire vulcanizing process is solved. The preheating device for the tire vulcanizing mold has reasonable structure, and is widely applied to the tire manufacturing industry.
Description
Technical field
The present invention relates to the tire vulcanizing device technical field, relate in particular to a kind of preheating device of large-scale or giant tyre sulfurizing mould.
Background technology
As everyone knows, after tire forming vulcanizer is shut down, before the sulfuration of normal dress tire, all to mould be carried out preheating.The purpose of preheating mainly is to guarantee the tyre vulcanization quality.Present preheating method on the market is a vacuum in the capsule, and outer temperature medium feeds the steam chamber heating of vulcanizer, and according to the size of mould, the generally warm outside medium of preheating continues 3-8 hour after reaching the technique initialization temperature.And this preheating method; Whole warm is because the effect of outer temperature steam pressure (the about 0.65MPa of load-carrying tire pressure generally, the about 0.33MPa of giant tyre), and with capsule being pressed on central authority or the die surface tightly, the salient angle of central authority makes capsule produce rapid the distortion; Generation in service life to capsule has a strong impact on; Particularly large-scale engineering tyre or diameter surpass 122 inches giant tyre vulcanizing equipment preheating, because the capsule wall thickness rate is thicker, effect on service life is comparatively serious.Many tiremakers capsule in the giant tyre production process is very low service life, and the damaged phenomenon of the continuous capsule of preheating all occurred.Capsule is damaged, not only causes to produce to interrupt, and influence the ordinary production plan, and tiremaker is also suffered bigger economic loss.
Summary of the invention
Technical problem to be solved by this invention is: a kind of preheating device of tyre vulcanized mould is provided, with solve large-scale or the giant tyre sulfidation in, the technical problem of capsule cracky during mould and die preheating.
For solving the problems of the technologies described above, technical scheme of the present invention is: the preheating device of tyre vulcanized mould, comprise upper die body and lower mold body, and said upper die body and lower mold body are arranged in the steam chamber of vulcanizing equipment; During matched moulds, form the tire die cavity between said upper die body and the lower mold body, be equipped with the aperture that is communicated with said steam chamber and tire die cavity on said upper die body and the lower mold body, be provided with capsule apparatus in the said tire die cavity; Said vulcanizing equipment is provided with the outer temperature medium channel that communicates with said steam chamber, and said outer warm medium channel has outer warm medium import and outer temperature media outlet; Warm medium channel in said capsule apparatus is provided with, said in warm medium channel have in warm medium import and Nei Wen media outlet; Outside said, be provided with a capsule inflation channel between warm medium channel and the interior temperature medium channel by valve control.
As a kind of improvement, said capsule inflation channel is arranged between said outer warm media outlet and the interior temperature medium channel.
As further improvement, said valve comprises two stop valves and is serially connected with the two-position three way stop valve between said two stop valves that an interface of said two-position three way stop valve is communicated with the emptying pipeline.
As further improvement, said two-position three way stop valve is the two-position three way pneumatic cut-off valve.
Owing to adopted technique scheme, the invention has the beneficial effects as follows: because outer temperature media outlet is communicated with through the capsule inflation channel with interior temperature medium channel, the capsule inflation channel is provided with valve; Make tire vulcanizing device in warm; The steam that comes out from steam chamber enters into capsule through the capsule inflation channel, and valve keeps unimpeded in whole warm, so the pressure in pressure in the capsule and the steam chamber keeps relative equilibrium; And this balance is a dynamic balance; Along with the change in pressure in the steam chamber, avoid the capsule inside and outside differential pressure excessive, cause capsule to be attached on the central authority; Run into step or turning and produce rapid distortion and damage capsule, brought into play the service life of capsule to greatest extent.Because the capsule inflation channel draws from the outer temperature media outlet of steam chamber, the pressure of outer temperature medium of having avoided introducing capsule is excessive, damages capsule; Improved security performance, only needing simultaneously increases by place's capsule inflation channel, just can solve large-scale or giant tyre flimsy problem of capsule in the vulcanizer warm; Utilize existing pipeline and resource; Small investment, effect is obvious, can popularize in the tire manufacturing industry.
Because the capsule inflation channel of the preheating device of tyre vulcanized mould is provided with two stop valves, between two stop valves, is in series with a two-position three way stop valve, an interface of two-position three way stop valve connects the emptying pipeline; Make the security performance of preheating device be improved, because when normal sulfuration, the pressure ratio of interior temperature medium is higher; And the pressure of outer temperature medium is relatively low, if the sealing property of stop valve is bad, can cause the interior temperature medium of high pressure to enter into steam chamber; Destroy normal sulfidation, two-position three way stop valve set between two stop valves has well solved this problem, and the two-position three way stop valve is in the vulcanizer warm; Be communicated with two stop valves, make steam chamber and capsule be communicated with, in the normal sulfidation of vulcanizer; The two-position three way stop valve is communicated with emptying pipeline and the stop valve that links to each other with capsule; Cut off two paths between the stop valve simultaneously, both made a stop valve occur leaking, in normal sulfidation; Warm medium is scurried in the steam chamber in also being unlikely to occur, and influences the normal sulfuration of tire.
