Abstract
The utility model relates to a tire vulcanization is with sealed mouth pad belongs to tire production facility field. The mouth pad is provided with a left lug boss of the mouth pad, a right lug boss of the mouth pad, a left sealing sub-port and a right sealing sub-port, the middle plane of the mouth pad is provided with a central line of the mouth pad, the left lug boss of the mouth pad and the right lug boss of the mouth pad are in a left-right asymmetric structure, the left sealing sub-port and the right sealing sub-port are also in a left-right asymmetric structure, the left shape and the right shape of the mouth pad after the left sealing sub-port and the right sealing sub-port are separated from the central line of the mouth pad are in a left-right asymmetric structure, the diameter of the left sealing sub-port is larger than that of the right sealing sub-port, and chamfers are processed on the left sealing sub-port and the right sealing sub-port. The beneficial effects of the utility model are that, solve to lead to vapour not smooth, sealed tight and punch askew partially, cause to step up slowly, leak, lead to the large tracts of land to lack to glue or directly lead to the condemned problem of tire, life increases to stabilize product quality, improve production efficiency, greatly reduce manual work and material cost simultaneously.
Description
Technical Field
The utility model relates to a tire production facility field says in detail a tire vulcanizes with sealed filter pad.
Background
As is known, in the field of tire manufacturing and processing, there is a vulcanization process, which adopts a quick-opening vertical pot type vulcanizing tank for vulcanization, the pot type vulcanization is characterized in that a nozzle pad is adopted between a mold and a mold for sealing, several pairs of molds are ensured to form a circulation channel through the sealing of the nozzle pad, if the internal and external quality of a product is directly influenced due to the sealing failure, the traditional design is two-sided symmetry, the sealing nozzle pad is provided with a left boss of the nozzle pad, a right boss of the nozzle pad, a left sealing sub-port and a right sealing sub-port, wherein the left boss of the nozzle pad and the right boss of the nozzle pad are in a bilateral symmetry structure, the left sealing sub-port and the right sealing sub-port are also in a bilateral symmetry structure, the left and right shapes are completely the same after being separated from a central line, punching needs to be carried out on the middle plane of the nozzle pad, a valve rod is installed, the nozzle pad is extruded and deformed when the two-wheel tire molds are pressed and closed, make left side sealed bead, right side sealed bead position diameter diminish, cause the latus rectum diminish in the valve pole department, influence the steam lead to effect and sealed not tight phenomenon, traditional way is that the manual left side sealed bead with the cutter with the mouth pad cuts the chamfer soon, though can reduce the not smooth phenomenon of steam lead to, nevertheless because of manual cutting size is not unified soon, can not solve sealed not tight phenomenon, still need frequent change, increase manual work and material cost, and have very big quality hidden danger. The sealing nozzle pad with the structure has the advantages that the drift diameter is reduced and the thickness is reduced after the nozzle pad is seriously deformed due to large stress of the upper surface, and in the vulcanization process, the pressure rise is slow and the leakage is caused due to unsmooth steam ventilation and poor sealing caused by deformation and aging of the sealing nozzle pad, so that large-area rubber shortage is caused or tires are directly scrapped.
Disclosure of Invention
In order to overcome the not enough of prior art, the utility model provides a tire vulcanization is with sealed filter tip pad solves to lead to vapour not smooth, sealed tight and punch askew partially, causes to step up slowly, leaks, leads to the large tracts of land to lack to glue or directly leads to the condemned problem of tire.
The utility model provides a technical scheme that its technical problem adopted is: a sealed nozzle pad for tire vulcanization is provided with a nozzle pad and is characterized in that a left boss of the nozzle pad, a right boss of the nozzle pad, a left sealing sub-opening and a right sealing sub-opening are machined on the nozzle pad, a center line of the nozzle pad is arranged on the middle plane of the nozzle pad, the left boss of the nozzle pad and the right boss of the nozzle pad are in a left-right asymmetric structure, the left sealing sub-opening and the right sealing sub-opening are also in a left-right asymmetric structure, the left shape and the right shape of the nozzle pad after the center line of the nozzle pad is separated are in a left-right asymmetric structure, the diameter of the left sealing sub-opening is larger than that of the right sealing sub-opening, and chamfers are machined on the left sealing sub-opening and the right sealing sub-opening.
The beneficial effects of the utility model are that, vulcanize out the direct shaping of mouth pad to increase the central line that punches in mouth pad circumference, cancel artifical cutter with sealed mouth pad mouth on with the mouth pad and cut the technology soon, solve to lead to vapour not smooth, sealed not tight and punch askew partially, cause to step up slowly, leak, lead to the large tracts of land to lack to glue or directly lead to the condemned problem of tire, and life increases, thereby stabilize product quality, and the production efficiency is improved, greatly reduce manual work and material cost simultaneously.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention, which is also a sectional view of the embodiment.
In the figure, 1, 2, right boss, 3, left boss, 4, left sealing seam allowance, 5, right sealing seam allowance and 6, central line of the mouth pad.
Detailed Description
In fig. 1, the utility model discloses the design shape of mouth pad 1 is for controlling asymmetric structure, is equipped with left boss 3 of mouth pad, mouth pad right side boss 2 and left sealed rim of a mouth 4, right sealed rim of a mouth 5 and mouth pad central line 6, and wherein left boss 3 of mouth pad, mouth pad right boss 2 are for controlling asymmetric structure, and processing has the chamfer on left sealed rim of a mouth 4, the right sealed rim of a mouth 5. The left sealing sub-port 4 and the right sealing sub-port 5 are also in a left-right asymmetric structure, the left shape and the right shape are completely different after being separated from the central line 6 of the mouth pad, especially the diameter of the left sealing sub-port 4 is larger than that of the right sealing sub-port 5, the central line 6 of the mouth pad is arranged on the middle plane of the mouth pad 1, the central line is punched, when a valve rod is installed, the left sealing seam allowance 4 of the nozzle pad 1 is installed upwards in a tire vulcanization mold, after the nozzle pad 1 is extruded and deformed when the two vulcanization molds are closed under pressure, the diameter of the position of the left sealing sub-port 4 still meets the requirement of the drift diameter size, the problems of large-area rubber shortage or direct tire scrapping caused by slow pressure rise and leakage due to the fact that the inner drift diameter of the valve rod is reduced to influence the steam through effect and poor sealing are solved, the service life is prolonged by 10 times, thereby stabilizing product quality, improving production efficiency and greatly reducing labor and material costs.
