Abstract
The utility model relates to a mold for producing an annular tread of a mineral giant reproduced tire. The mold comprises an upper mold, a lower mold and a core mold. By the mold, the production of large-specification annular pre-vulcanized treads is achieved, the blank in design of a mold with the specification in China is made up, and the problem that glue is hard to inject because of a large mold chamber is solved.
Description
Technical field
The utility model relates to a kind ofly for manufacturing the equipment of tire production annular tire tread, particularly a kind of giant mining is manufactured the production mould of tire circular tread more again.
Background technology
Traditional ring shaped precuring tire casing mould, mostly be the lorry tyre tread mould of some small dimensions, and the manufacture method of these ring shaped precuring tire casings, all the rubber mixing to be pressed into the adhesive tape of certain specification size, be wrapped in die cavity, contraction and external force by active module are pressurizeed, and make ring shaped precuring tire casing.But there are a lot of drawbacks in this traditional process: 1, complex procedures 2, increased workman's the amount of labour 3, when segmented mold shrinks, easily make sizing material flow in the gap of active module, cause a large amount of glue limits 4, can not carry out the production of large specification ring shaped precuring tire casing.
By the end of so far, domestic also do not have giant mining to manufacture tire ring-type tread mould again in addition, for measurement and the computational methods of making this mould desired data, and the technological requirement of mould or a blank.And the utility model is from the calculating that measures later data of mould primary data, and the technological requirement of mould has all been carried out the design of system, and be verified in actual applications, filled up the blank that domestic giant mining is manufactured the design of tire ring-type tread mould again.
Summary of the invention
The utility model technical issues that need to address are, overcome the deficiency of background technology, provide a kind of giant mining to manufacture the production mould of tire circular tread again.
For achieving the above object, the technical solution of the utility model is:
Giant mining is manufactured a production mould for tire circular tread again, comprises upper die and lower die and core, it is characterized in that: on average in four orientation of described patrix, respectively process a gum-injecting port, the center overall diameter of described core is 320cm.
Optimize, also comprise mould decorative pattern, groove is narrow, and pattern block is roomy, and decorative pattern saturation degree is 70%～80%.
Use beam calliper to measure (having error) to tire polishing position, and according to the contraction situation of thick rubber, get corresponding shrinkage factor, and then it is high to calculate dies cavity.
Measuring sample tire base glue thickness is Amm, and measuring sample bead wire belt diameter is Bmm, remaining 3mm, and tyre surface diameter dimension is Z=(B+3
2+1.2
a)/(1+0.03), and after sulfuration, tyre surface has certain contraction, core center overall diameter is the corresponding shrinkage factor of Z/(1-).
GB regulation: deepen pattern depth and get 82mm, actual measurement pattern depth 86mm, adds circular tread base portion glue thickness owing to manufacturing the reserved 3-6mm of tire base glue thickness again, if select pattern depth 86mm, then manufactures tire and will exceed former tire outside dimension.Select 82mm, can meet GB and require to reach again the anti-puncture of tire, wear-resisting requirement.
It is little that mould decorative pattern of the present utility model has heat-dissipating, and rapid heat dissipation is wear-resisting, and the good and breach not of self-cleaning, does not fall the characteristics such as piece.
Because of dies cavity excessive (its overall diameter reach 3m more than), for better, to injecting glue in die cavity, on average in four orientation of patrix, respectively process a gum-injecting port.
The utility model has the advantage of: 1, realized the production of large specification ring shaped precuring tire casing, filled up the blank of domestic this specification Design of Dies; 2, the utility model Pattern Design is unique, has improved the serviceability of ring shaped precuring tire casing; 3, solved because of mould cavity excessively, be difficult to the problem of injecting glue; 4, make to produce ring shaped precuring tire casing technique and more succinctly facilitate, be applicable to batch production; 5, the ring shaped precuring tire casing more stable quality that makes production, outward appearance is cleaner and tidier.

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
As shown in the figure, a kind of giant mining is manufactured the production mould of tire circular tread again, comprises upper die and lower die and core, it is characterized in that: on average in four orientation of described patrix, respectively process a gum-injecting port, the center overall diameter 3 of described core is 320cm.
Optimize, also comprise mould decorative pattern, groove is narrow, and pattern block is roomy, and decorative pattern saturation degree is 70%～80%.
Use beam calliper to measure (having error) to tire polishing position, and according to the contraction situation of thick rubber, get corresponding shrinkage factor, and then it is high to calculate dies cavity.
Measuring sample tire base glue thickness is Amm, and measuring sample bead wire belt diameter is Bmm, remaining 3mm, and tyre surface diameter dimension is Z=(B+3
2+1.2
a)/(1+0.03), and after sulfuration, tyre surface has certain contraction, core center overall diameter 3 is the corresponding shrinkage factor of Z/(1-).
GB regulation: deepen pattern depth and get 82mm, actual measurement pattern depth 86mm, adds circular tread base portion glue thickness owing to manufacturing the reserved 3-6mm of tire base glue thickness again, if select pattern depth 86mm, then manufactures tire and will exceed former tire outside dimension.Select 82mm, can meet GB and require to reach again the anti-puncture of tire, wear-resisting requirement.
It is little that mould decorative pattern of the present utility model has heat-dissipating, and rapid heat dissipation is wear-resisting, and the good and breach not of self-cleaning, does not fall the characteristics such as piece.
Because of dies cavity excessive (its overall diameter reach 3m more than), for better, to injecting glue in die cavity, on average in four orientation of patrix, respectively process a gum-injecting port.
As mentioned above, given scheme content, can derive similar technical scheme in conjunction with the accompanying drawings and embodiments.In every case be the content that does not depart from technical solutions of the utility model, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
