Go out.Between 0.5mm to 5mm, the design expands distance after can avoiding tire tube air-inflating between adjacent warp, is expressed to spiral latitude
Inside line, the phenomenon for causing to hinder the inner tube of a tyre to spill the flowing of air-flow and collect is produced, and prevent leakage gas can not be reached out smoothly
Gas port.
Preferably, described lowering or hoisting gear includes hydraulic jack and guide upright post, and hydraulic jack is arranged on by support frame
Above upper mould, the upper mould of output shaft lower end connection of hydraulic jack, output shaft both sides are arranged with guide upright post.Lowering or hoisting gear is not only
Mould oscilaltion can be made, and mould can be compressed, make upper die and lower die closely fasten to form confined space, prevented from knot
Gas leakage at conjunction, guide upright post play the guiding role, and make operation more steady.
Described lowering or hoisting gear includes cylinder and guide upright post, and cylinder is arranged on above upper mould by support frame, cylinder
The upper mould of output shaft lower end connection, output shaft both sides are arranged with guide upright post.
The inner tube of a tyre detection method carried out using inner tube of a tyre detection means, has following steps：
A. the inner tube of a tyre to be detected is put into lower mould, the charging connector of the inner tube of a tyre stretches out from inflation inlet；
B. lowering or hoisting gear drives upper mould to decline, and upper mould is fastened on directly over lower mould, forms an airtight chamber；
C. inflated using aerating device by inflation inlet into the inner tube of a tyre, the gas channel in the inner tube of a tyre and airtight chamber of expansion
It is in close contact；
D. gas leakage is judged whether, if gas leakage, gas is collected by gas channel and discharged from gas outlet, air pressure detection
Device detects air pressure change；If air tight, pressure test device is unchanged；
E, deflated by inflation inlet, take out the inner tube of a tyre, complete detection.
Compared with prior art, beneficial effect possessed by the above-mentioned technical proposal of the inner tube of a tyre detection means is：
1st, automatic detection inner tube of a tyre air-tightness, labor strength is reduced：The lower mould of design and can automatic lifting upper mould, and
Gas channel is covered with upper die and lower die inwall, upper mould or lower mould offer gas outlet；If there is gas inner tube of a tyre optional position
Leakage, gas can be discharged by gas channel from gas outlet, and gas outlet, which can connect air gauge or other, can detect gas
Body whether the detection means of seepage, whether observation has gas permeation, so as to realize automatic detection inner tube of a tyre air-tightness, without using existing
There is the artificial detection method under technology, substantially reduce labor strength.
2nd, the unique gas channel for being interlocked and being formed by spiral parallel and warp of design, can detect inner tube of a tyre optional position
Gas leak phenomenon, whole detection process is rigorous accurate, is not in detection error situation, greatly improves product export qualification rate.
