Description
Technical field
The utility model is related to a kind of tire-mold, it is adaptable to riding tire, light truck tire, engineering tire, loose die for giant tire, tool
Saying for body, is related to a kind of vacuum type tyre adjustable die, belongs to tire-mold technical field.
Background technology
Tyre adjustable die is that tyre vulcanization shaping must equipment.At present, tire vulcanization process is summarized as follows：Tire base is put
Put and be heated in 180 DEG C or so of mould, fetus is pressed into sidewall plate and pattern block by being inflated in moulding capsules, tire base and
Gas between wall of die cavity is extruded by green tyre, is passively discharged, is made from the steam vent of sidewall plate and pattern block
Green tyre can fill up die cavity, and green tyre starts vulcanization until vulcanization is completed.
Tire is in sulfidation, and the gas between tire base and die cavity must be discharged in time, if can not discharge in time, gas will be residual
Stay at the dead angles such as decorative pattern, can so cause occur starved at the dead angle after the completion of tyre vulcanization, tire is scrapped.To make gas
Smooth discharge, mould can be vented demand according to tire, a large amount of steam vents, tire base and mould are processed in cavity surface in processing
Gas is discharged by steam vent between tyre surface.But this kind of exhaust mode, the discharge of gas is completed by the extruding of moulding capsules,
But sometimes because the Position Design of tyre surface stomata is unreasonable, stomata is blocked not timely clear and coherent, tire contour shape by sizing material and designed
Unreasonable etc., traditional exhaust mode, easily causes gas residue at decorative pattern or other dead angles, can still go out after tyre vulcanization
Show starved defect and turn into waste product.Meanwhile, a large amount of stomatas are processed on tire die cavity, the sizing material of fetus can also be squeezed into steam vent
It is interior, a large amount of adhesive tape are left in surface of tyre after the demoulding, Appcarance guality of tyres is largely effected on, while also resulting in the waste of sizing material.For
Raising Appcarance guality of tyres also increases the production cost of tire, it is necessary to manually trimmed to adhesive tape.
It is existing that the mould structure part that the mould vacuumized is mainly inside mould structure, may be with external world's ventilation is provided
Between joint face on process seal groove, place sealing ring.The mould that vacuumizes of this mode is generally required to design completely and added
The mould of work brand new, not only needs to recalculate the joint face size of mould leakage, and need to consider each structural member
Between annexation matching relationship, it is very high to the requirement on machining accuracy of each joint face, cause design processing cost very
