The set sulfuration process of glue vulcanizes rubber.Further, in order to guarantee that die ontology will not in Vulcanization Process of Rubber
It is softened, downward pressure can be applied to upper die body by pressing device, which need to guarantee that clamp force is greater than the swollen mould of rubber
Power.Further, the pressure that clamp force generates is greater than 30MPa, it is preferred that the pressure that clamp force generates is greater than 50MPa.
Specifically, set vulcanization process, includes the steps that heating mold, to control in Vulcanization Process of Rubber
Curing temperature, vulcanize rubber according to set sulfuration process.
SO3: the signal of the swollen mould force value of output characterization rubber is to detection device, and the detection device is for showing swollen mould power
The curve that value changes over time.
It will test part to connect with detection device, in Vulcanization Process of Rubber, swollen mould power is acted in trunk portion, to pass through
Detection piece detects the value for the swollen mould power that trunk portion is born.Detection piece exports the signal for characterizing swollen mould force value to detection device, and
The curve that the value of swollen mould power changes over time is shown by detection device.Preferably, detection time is more than or equal to the normal of rubber
Vulcanization time guarantees to stop detection after vulcanization.
The above is only a specific embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
