Description
Technical field
The invention belongs to tyre vulcanization technical field, more particularly to a kind of pattern block with extensive decorative pattern shape applicability
And tire-mold.
Background technology
In tire vulcanization process, in order to rubber can be distributed evenly in mould, it is necessary to discharge the sky in mold cavity
Gas, prior art typically using opening up multiple steam vents in pattern blocks of tire mold, and steam vent depth penetration pattern block
Radial thickness, wasted time and energy during exhaust hole machined, therefore increased the workload and manufacturing cost in pattern block process,
It is unfavorable for improving operating efficiency.On the other hand, in sulfidation, rubber can be extruded into forming glue hair, vulcanization in steam vent
After the completion of, glue hair in part can be broken in steam vent, and glue hair can hinder the smooth discharge of type chamber air and then influence next time
Sulfidation is smoothed out, therefore, not only need to prune the glue hair on tire, and need to unload tire-mold
Glue hair in steam vent is cleared up, the outward appearance of sizing material and influence tire product is not only wasted, and is greatly reduced vulcanization
The operating efficiency of work.
In order to solve the drawbacks described above that steam vent brings, those skilled in the art propose the pattern block of non air exit hole, main
It is divided into two kinds：One kind is vertical piecemeal, circumferential to be divided by pitch units；Another horizontal resection, by a monoblock pattern block point
Layered structure.But the pattern block of both structures is larger by the limitation of tyre tread, can be only applied to certain several specific
Pattern block, without extensive decorative pattern shape applicability.
Chinese patent CN1070708A proposes a kind of dual damascene composite construction Non-airhole type activating mold, its flower
Line block includes the decorative pattern block body of split type steel construction and aluminium flake, and decorative pattern block body is formed by multi-disc pattern sheet is stacked,
And the either end facet processing annular groove of pattern sheet, edge sets aluminium flake in annular groove, is mounted to combined type Pattern body, each aluminium flake and pattern block
Exhaust passage is provided between body.The decorative pattern block structure phase of the split type pattern block of the invention and foregoing the first non air exit hole mould
Together, save steam vent and good ventilatory effect can be reached, but the pattern block equally may be only available for specific decorative pattern
Block, limitation is big.
Therefore it provides a kind of pattern block and tire-mold, can be applied to various decorative pattern shapes, for people in the art
