Description
Technical field
The invention belongs to cover tire side walls；And its protection, decoration, mark or similar device field, and in particular to a kind of colour
The manufacturing technique method of tire.
Background technique
With the industries such as automobile, motorcycle, electric vehicle it is fast-developing they to have become people indispensable in different regions
Few running tool, tire is exactly black in people's memory, and in the past 10 years, people's lives are horizontal higher and higher to personalization
Product increasingly favor, tire is no exception.Such as the tire of offroad vehicle configuration, its sidewall trade mark becomes white or other colors
Profile, it is more eye-catching and have very much individual character；The development of motorcycle tyre and electric vehicle tyre with tire machinery equipment, cold feeding
Tyre surface compounding extruder was also grown up and was widely used at nearly 8 years, and then how people are also in research by motor and electricity
Vehicle tire becomes colorization and meets people to personalized pursuit, and more enterprise is all in research cold feeding two or triplex
Extruder carries out colored sizing material and black sizing material is compound that tire is made to become colorization, the color tyre of this technique manufacture: (1) material
Expect at high cost；(2) most colors only have 2 kinds on a tires；(3) sidewall upper mold cannot be carved to any one word and change face
Color；(4) since colored sizing material cannot use many supporting materials, flexible resistance when on tire sidewall is poor,
It is easily cracked；And automobile tire tyre with raised white letter production technology using by tread rubber it is compound after move finished tire to autocratic wheel again
It is completed after being ground and (grinding off the black glue of surface covering, expose the coloured glue of bottom) modification on tire character-grinding machine, technique is numerous
It is trivial, equipment investment is big, at high cost.
Summary of the invention
The purpose of the present invention is to provide a kind of manufacturing technique methods of colored tire, color using production method production tire
Color font or pattern firmness are big, any one font or pattern can be changed color, and simple production process.
In order to achieve the above objectives, base case of the invention is as follows:
The manufacturing technique method of colored tire, is produced using sulfurizing mould, and the sulfurizing mould includes upper die and lower die, on
Mould, lower die are equipped with muti-piece and are detachably connected respectively with upper die and lower die and have the active block of indent font or pattern；Producer
Method the following steps are included:
(1) active block with indent font or pattern is placed in insulating box and is heated；
(2) active block is taken out after step 1, and the coloring agent of different color is injected into same active block or difference
On the indent pattern or font of active block；
(3) active block after step 2 to be injected to coloring agent, which is placed again into take out after heating 3-5min in insulating box, is put into vulcanization
On the upper die and lower die corresponding position of mold；
(4) tyre semi-finished products that colorization will be needed to handle are packed into sulfurizing mould, and press the molding of sulfurizing mould by
Button rear tyre enters the vulcanization heating period；
(5) vulcanization terminates and tire is taken out to the production for completing color tyre from sulfurizing mould.
This programme has the advantages that
1, in step 2, the coloring agent of different color can be injected into the indent pattern of same active block or different active blocks
Or in font, different fonts or pattern can be adjusted to different colours in this way, same font or pattern can be also adjusted to
Different colours, so tire sidewall font produced by the present invention or pattern, which can according to need, formulates different colours or different positions
It sets, different size, tire personalization is full；
2, coloring agent of the invention passes through step 2 pre-add thermoforming twice first, is then molded over by vulcanizing the heating period
On the sidewall of tire, coloring agent and tire sidewall can be made to be completely combined integrally using such molding, therefore this technique makes tire
Colored font or pattern firmness are big, do not fall after use, do not split, is colour-fast；
3, the present invention in, the colored font or pattern of tire sidewall be by the coloring agent on active block tire sidewall at
The color tyre of type, the production of this technique is only the materials of a font or pattern, and colored sizing material materials are low；And the present invention is complete
Colored sizing material and the compound mode for making tire become colorization of black sizing material are abandoned entirely, to solve because colored sizing material is used in
Behind the position of sidewall intolerant to flexion and can not volume production worry；
4, color tyre production method of the invention is to form to realize in tire sidewall by the coloring agent on active block, is broken
The technique that conventional composite formula tyre surface extrudes and mill word realizes tire sidewall colorization, it is clear that technique is simpler, and to sulphur
Change that scrap build is at low cost, forms the time more 2 of the whole operation process of colored font or pattern only more conventional vulcanized operation
Minute or so, production efficiency greatly improves.
We begin to set about to carry out the research and development of tyre with raised white letter production technology in October, 2015, many detours of passing by,
Always it fails because volume production is unable to；Start in April, 2016 and colored font tire is analyzed and simulated.By multiple
Modification, finally determines the design producing process of above-mentioned color tyre.
Prioritization scheme 1, advanced optimizes base case, and the heating temperature of insulating box is 60-80 DEG C in step 1.Hair
Bright people in experiments it is found that, control insulating box within the scope of above-mentioned temperature, the coloring agent that is infused on active block font or pattern
Molding effect it is preferable.
Prioritization scheme 2 advanced optimizes base case, 1 any one of prioritization scheme, the active block by magnetite with
Upper mold or lower die connection.It is connected by above-mentioned connection type, energy disassembled and assembled freely active block, injects coloring agent convenient for taking out active block,
And the active block for being put into upper mold or lower die after coloring agent heating, and being placed in upper mold or lower die will not drop out.
Prioritization scheme 4 advanced optimizes base case, 1 any one of prioritization scheme, the active block and upper mold or under
The gap of mould cooperation is less than 0.01mm.The gap control that active block and upper mold or lower die cooperate within the above range, is avoided that into
Active block shifts when type, to guarantee font or the accuracy of pattern forming position on active block.
