Technical Field

Background
At present, a tire mold with a single specification can only vulcanize a tire with one aspect ratio, but in the existing tire specification, tires with the same width and corresponding to different aspect ratios exist. Therefore, in the current tire production process, even if the width of the tire is not changed, when the height of the tire is changed, a tire mold with a new specification needs to be developed, so that the specifications of molds which need to be reserved in a tire factory are various, and the manufacturing cost of the tire is increased.
In addition, for the tire mold of the aluminum pattern block, the tire vulcanization process is different due to different rubber compound formulas or different tire performance requirements, wherein the most important parameter is the vulcanization temperature, but the tire mold used for vulcanization is of the same specification. The expansion amount of the aluminum pattern block is different under different vulcanization temperatures, and the current method for calculating the expansion amount of the mold is (vulcanization temperature-A ℃) multiplied by the linear expansion coefficient of corresponding materials (the linear expansion coefficient value is a value under A ℃), and the clearance of the pattern block of the tire mold is changed due to the change of the expansion amount. For example, when the vulcanization temperature is 175 ℃, the annular edge formed by the matching of the side plate of the tire mold and the caliber of the block and the vertical edge formed by the matching of the block and the block have no gap, and no rubber edge is generated in the vulcanized tire. However, when the vulcanization temperature is adjusted to 160 ℃, the expansion amount of the pattern blocks is reduced, vertical seams appear between the pattern blocks, and the appearance and the quality of the vulcanized tire are affected by the rubber edges of the vulcanized tire.
In conclusion, a set of tire molds needs to be manufactured correspondingly for each tire with each aspect ratio or the vulcanization temperature, so that the production cost is too high, and the actual production is not facilitated.

As described in the background of the invention, in the actual production of existing tires, there is a need to stock a large number of tire molds of different specifications for at least two reasons, namely, different aspect ratios and different vulcanization temperatures.
In view of the above, the present disclosure designs a variable caliber device, such as an insert, at the caliber of the tire mold pattern block, a gasket can be added at the contact position between the back surface of the insert and the pattern block, and the caliber of the pattern block can be changed by adjusting the thickness of the gasket, so as to adapt to different vulcanization temperatures. Or the caliber of the pattern block of the tire mold is designed with an inlay block, a spring is added between the back of the inlay block and the pattern block, and the caliber change of the pattern block is realized by adjusting the compression amount of the spring so as to adapt to different vulcanization temperatures.
In particular, the description is made as different embodiments.
First, as an alternative, in the first embodiment, as shown in fig. 1, an insert block is designed at the block caliber, and the insert block is connected with the block through a connecting screw. By replacing the mosaic blocks with different thicknesses, the caliber size of the pattern block is changed, the height-width ratio of the tire is adjusted, the mold is saved, and the manufacturing cost of the tire is reduced. This scheme is suitable for steel decorative pattern piece and aluminium matter decorative pattern piece simultaneously.
As an alternative, as shown in fig. 2, the mosaic block is positioned and connected with the pattern block by a connecting screw and a positioning pin, and the mosaic block and the pattern block are ensured to be positioned smoothly by the positioning function of the positioning pin.
When the embodiment is used for solving the problem of different aspect ratios of the tire, the principle of replacing the mosaic blocks with different thicknesses is adopted, the thickness of the reference mosaic block plus the width of the tire is multiplied by the variation of the aspect ratio, according to industry experience data, the common aspect ratio of the tire is 45% -65%, and the reference mosaic block is designed according to the minimum aspect ratio of 45%.
As an example, the width of the tire is 205mm, the thickness of the reference mosaic block is 10mm, and the aspect ratio of the tire needs to be changed from 45% to 50%, namely, the replacement thickness is: 10+205 × (50% -45%) 20.25mm mosaic pieces.
Of course, it is understood that the parameters provided in the above embodiments are merely examples, and the adjustment of the parameter sizes may be performed by one skilled in the art according to the influence factors such as the specific tire size or the working environment.
When the present embodiment is to solve the problem caused by the variation of the vulcanization problem, the principle of replacing the mosaic blocks of different thicknesses is due to the impossibility of providing a plurality of mosaic blocks of different thicknesses. For example, t1 in the range of 160 ℃ to 165 ℃ and t2 in the range of 165 ℃ to 170 ℃. The thickness of the specific mosaic block is calculated according to the actual size of the die, the vulcanization temperature and the thermal expansion coefficient of the mosaic block and the side plate material, and after the vulcanization temperature and the corresponding mosaic block are changed, the vulcanization gap is guaranteed to be within 0.02-0.04 mm.
As a calculation example, the block material is aluminum, and the coefficient of thermal expansion of the aluminum is about 24X 10-6The side plate is made of steel with a thermal expansion coefficient of about 11 multiplied by 10 DEG C-6/° C, the aperture of the pattern block is 590mm, the thickness t1 of the mosaic block is 10mm within the range of 160-165 ℃ of the vulcanization temperature, and when the vulcanization temperature is 165-170 ℃, the thickness t2 of the mosaic block is t1+ the temperature variation x (the coefficient of thermal expansion of aluminum-the coefficient of thermal expansion of steel) multiplied by the aperture of the pattern block/2 +/-the tolerance is approximately equal to 10.02 +/-0.01 mm. Supplementary explanation: in the example, the vulcanization temperature is increased from 160-165 ℃ to 165-170 ℃, the expansion amount of the pattern block is increased, the pattern block is firstly contacted with the pattern block, the caliber of the pattern block cannot be contacted with the excircle of the side plate, and the circular seam of the mold is caused, so that the mosaic block needs to be thickened to compensate the problem of the seam caused by the change of the vulcanization temperature.
In the calculation process, the parameters such as the corresponding expansion coefficient and the like can be changed due to different materials and the like of the pattern blocks, and meanwhile, the expansion coefficient, the thickness of the mosaic block and the like are considered, so that the adjustment of a small compensation amount can be carried out.
It is understood that the parameters provided in the above embodiments are merely examples, and the adjustment of the parameter size may be performed by one skilled in the art according to the influence factors such as the specific tire size or the working environment.
Alternatively, as a second embodiment, as shown in fig. 3 and 4, an insert block is designed at the block caliber, and the insert block is connected with the block through a connecting screw.
In order to satisfy the thickness adjustment principle of different aspect ratios of the tire, it is consistent with the first embodiment and will not be described herein again.
When the vulcanization temperature changes, an adjusting gasket is added at the contact position of the back surface of the mosaic block and the pattern block to realize the change of the caliber size of the pattern block, ensure no clearance between a side plate and the pattern block of a tire mold and between the pattern block and the pattern block during vulcanization, and realize no rubber edge of the vulcanized tire.
The thickness of the mosaic block is designed according to the lowest vulcanization temperature. The principle of changing the shim, the shim thickness ═ vulcanization temperature variation/5 ℃x0.02 mm, as: when the vulcanization temperature changes by 0-5 ℃, adding an adjusting gasket of 0.02 +/-0.01 mm; when the vulcanization temperature changes by 5-10 ℃, a gasket with the thickness of 0.04 +/-0.01 mm is added.
In the calculation process, the material of the pattern block and the material of the adjusting gasket are different, so that the corresponding parameters such as the expansion coefficient and the like can be changed, and meanwhile, the expansion coefficient, the thickness of the mosaic block and the like are considered, so that the adjustment of a small compensation amount can be carried out.
It is understood that the parameters provided in the above embodiments are merely examples, and the adjustment of the parameter size may be performed by one skilled in the art according to the influence factors such as the specific tire size or the working environment.
Alternatively, as a third embodiment, as shown in fig. 5 and 6, an insert block is designed at the caliber of the block, and the insert block is positioned and connected with the block through a positioning pin and a connecting screw. The springs are added between the back surfaces of the mosaic blocks and the pattern blocks, the change of the expansion amount of the pattern blocks caused by the change of the vulcanization temperature is compensated by adjusting the compression amount of the springs, no gap is left between the side plates and the pattern blocks of the tire mold and between the pattern blocks during vulcanization, and the vulcanized tire is free of rubber edges.
The compression of the spring is required to meet the caliber size change caused by the vulcanization temperature change, such as: the designed variation range of the vulcanization temperature is 185-160 ℃, the compression is 0.004mm at each variation of 1 ℃, the tolerance is +/-0.002 mm, the minimum compression amount is (185-160) × 0.004-0.1 mm, and the tolerance is +/-0.025. Supplementary explanation: when the tolerance accumulation reaches +/-0.025, the tolerance is not increased.
It is understood that the parameters provided in the above embodiments are merely examples, and the adjustment of the parameter size may be performed by one skilled in the art according to the influence factors such as the specific tire size or the working environment.
When the compression amount of the spring is adjusted, the design of the caliber is different from that of the first embodiment and the second embodiment, the design is a conical surface, the conical surface can play a guiding role, and the mosaic blocks are guaranteed not to incline.
For more clear explanation, as shown in fig. 7(a) -7 (d), the aluminum blocks have different expansion amounts at different vulcanization temperatures, and the conventional method for calculating the mold expansion amount is (vulcanization temperature-a ℃) multiplied by the linear expansion coefficient of the corresponding material (the linear expansion coefficient value is a value at a ℃), and the gap between the tire mold blocks changes due to the change in the expansion amount.
As an example, the corresponding material is aluminum.
When the vulcanization temperature is the designed vulcanization temperature, the annular edge formed by the matching of the tire mold side plate and the pattern block caliber and the vertical edge formed by the matching of the pattern block and the pattern block have no gap, and no rubber edge is generated in the vulcanized tire. However, when the vulcanization temperature is adjusted to be lower than the designed vulcanization temperature, the expansion amount of the pattern blocks is reduced, the requirement cannot be met, vertical seams appear between the pattern blocks, and the appearance and the quality of the vulcanized tire are affected due to the rubber edges of the vulcanized tire. When the vulcanization temperature is adjusted to be higher than the designed vulcanization temperature, the expansion amount of the pattern blocks is increased, if the pattern blocks exceed the standard, annular flash seams appear between the pattern blocks, and the appearance and the quality of the vulcanized tire are affected by the rubber edges of the vulcanized tire.
By adopting the scheme provided by the disclosure, taking the second embodiment as an example, as shown in fig. 8(a) and 8(b), when the vulcanization temperature changes, the tread blocks can be ensured not to have vertical seams only by changing the thickness of the adjusting shim to compensate for the gap change.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
Although the present disclosure has been described with reference to specific embodiments, it should be understood that the scope of the present disclosure is not limited thereto, and those skilled in the art will appreciate that various modifications and changes can be made without departing from the spirit and scope of the present disclosure.
