Another aspect of the present invention additionally provides a kind of to be connected using rubber core injecting glue described in any of the above-described embodiment
Device realizes the connection method of rubber core injecting glue connection, comprising the following steps:
The end of two rubber cores to be connected is cut out together, cleaning cuts surface, is placed in the interior membrane cavity 46 of gel-injection mould 4
In, rubber core is fixedly clamped by clamp system 5.It include: using 300C to the cleaning for cutting surfaceWSand paper surface is beaten
It polishes whole, makes surface without overlap, particle caused by cutting and breakpoint etc., using cleaning solution clean the surface and dry.
According to the volume of the length of injecting glue junction and inside cavity 46, sizing material usage amount is calculated；Sizing material is insufficient in order to prevent,
When sizing material weighs, it is further added by 5g or so on the basis of the sizing material usage amount of calculating, load weighted sizing material is placed in injecting glue
In slot 43, being preheated to sizing material becomes flowing shape；The material of sizing material and the material of rubber core are consistent.It should be noted that in sizing material
Selection on, it is desirable that crosslinking material is consistent with the material of rubber core, and otherwise sizing material and rubber core material are inconsistent, can exist bonding
Insecure or unconnected problem；Moreover, junction is partially soft, easily there are problems that discounting if the sizing material hardness of selection is low；If selection
Sizing material excessive high hardness, junction is partially hard, and there are inflexible problems.
The pressure for imposing 5MPa ± 0.5MPa to the sizing material in injecting glue slot 43 by moulding column 3, makes sizing material be flowed into inner membrance
In chamber 46, and it is full of interior membrane cavity 46.It should be noted that in the selection of pressure, the too small glue that can make injecting glue junction of pressure
Expect that density is small, connects relaxation；Pressure is excessive, can make rubber core to be connected is mobile even to deform；Suitable pressure limit is 5MPa
± 0.5MPa, suitable pressure can be 4.5MPa, 5MPa, 5.5MPa.
Heating gel-injection mould 4 makes the rubber vulcanization in interior membrane cavity 46, and curing temperature is 162 DEG C ± 3 DEG C, vulcanization time 15
±2min.It should be noted that curing temperature is too low in the selection of curing temperature and time, the time is short, injecting glue can be made to connect
It is insecure to locate partially soft or bonding；Curing temperature is excessively 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；When suitable vulcanization
Between range be 15 ± 2min, suitable vulcanization time can also be 13min, 15min, 17min.
After vulcanization completely, pressure is laid down, unclamps clamp system 5, the smooth rubber core taken out after connection avoids curved under high temperature
The junction Qu Zaocheng cracking, is placed in and cools down at room temperature, clears up the redundant rubber stock of injecting glue junction after cooling, and polish flat, obtains
The rubber core connected to injecting glue.
Rubber core, the outer diameter of injecting glue junction and former rubber are connected using the injecting glue that the connection method of the present embodiment obtains
Core outer diameter difference is only 0.12mm, within the internal diameter error range of sebific duct production, can be used for producing sebific duct；To obtained rubber core
Toughness detected, injecting glue junction is under the pulling force of 2000N without cracking；By rubber chip bending at 5 times of nominal outside diameter
It on mandrel, is placed in 150 DEG C of ageing oven, after parking 168h, injecting glue junction is without cracking.
In addition, when 461 diameter of injecting glue linkage section of interior membrane cavity 46 is greater than 463 diameter of rubber core placement section, rubber to be connected
Placement location of the glue core end in interior membrane cavity 46, has an impact to the outer diameter of injecting glue junction, is described as follows:
When adjusting the position wait connect rubber core end and being aligned with the small end for seamlessly transitting section 462, obtained injecting glue connects
Connect rubber core, injecting glue junction and former rubber core are almost the same, raw in sebific duct there is only the recess that depth at two is 0.12mm
Within the internal diameter error range of production；When adjust the position wait connect rubber core end with seamlessly transit section 462 big end be aligned when,
Obtained rubber core, the outer diameter of injecting glue junction and former rubber core outer diameter are completely the same.
