±2min.It should be noted that in the selection of curing temperature and time, curing temperature is too low, the time is short, can connect injecting glue
Place is partially soft or is bonded insecure；Curing temperature is too high, the time is long, then injecting glue junction can be made partially hard or not flexible；Suitable
Sulfurizing temperature range is 162 DEG C ± 3 DEG C, and suitable curing temperature can also be 159 DEG C, 162 DEG C, 165 DEG C；During suitable vulcanization
Between scope be 15 ± 2min, suitable cure time can also be 13min, 15min, 17min.
After vulcanization completely, pressure is laid down, unclamp clamp system 5, the smooth rubber core taken out after connection, it is to avoid curved under high temperature
Qu Zaocheng junctions are ftractureed, and are placed in and are cooled down at room temperature, and the redundant rubber stock of injecting glue junction is cleared up after cooling, and are polished flat, and are obtained
To the rubber core of injecting glue connection.
The injecting glue obtained using the connection method of the present embodiment connects rubber core, the external diameter of its injecting glue junction and former rubber
Core external diameter difference is only 0.12mm, within the internal diameter error range of sebific duct production, can be used to produce sebific duct；To the rubber core for obtaining
Toughness detected that its injecting glue junction is under the pulling force of 2000N without cracking；By rubber chip bending in 5 times of nominal outside diameter
On mandrel, it is placed in 150 DEG C of ageing oven, after parking 168h, injecting glue junction is without cracking.
In addition, when the injecting glue linkage section 461 of interior membrane cavity 46 is with diameter greater than rubber core 463 diameter of placement section, rubber to be connected
Placement location of the glue core end in interior membrane cavity 46, the external diameter to injecting glue junction has an impact, is described as follows：
When the position for adjusting rubber core end to be connected is alignd with the small end for seamlessly transitting section 462, the injecting glue for obtaining connects
Rubber core is connect, its injecting glue junction is basically identical with former rubber core, it is the depression of 0.12mm to only exist depth at two, in sebific duct life
Within the internal diameter error range of product；When the position for adjusting rubber core end to be connected is alignd with the big end for seamlessly transitting section 462,
The rubber core for obtaining, the external diameter of its injecting glue junction is completely the same with former rubber core external diameter.
