Less than 0.5 millimeter, then end plate is installed, end plate is completely embedded by bolt with upper die and lower die, it is preferred that in end plate and upper mould
Rubber slab is laid and lower mould between, makes better seal between end plate and upper die and lower die；
6th step, negative pressure is sturdy, and the mould after matched moulds is integrally put into vacuum bag, and vacuum connects mouth and is exposed at outside vacuum bag
Side, vacuum is connect and sealed between mouth and vacuum bag, and negative pressure 0.08-0.1Mpa, more than 30 minutes time, in 5 minutes are taken out to hermetic bag
Vacuum meter reading declines no more than 0.017Mpa, makes the rubber slab in mould sturdy with mould；
7th step, solidification, mould is put into curing oven together with vacuum bag, by the vacuum valve on vacuum bag and solidification
The negative tube connection of stove, keeps being heated after negative pressure 0.08-0.1Mpa in vacuum bag, and heating rate is set to 1.5 DEG C/min, most
High-temperature is set to 175 DEG C, keeps malleation 0.6MPa ± 0.01MPa in curing oven, 175 DEG C of constant temperature ± 10 minutes 120 minutes, so
After start cooling, when temperature drops to 60 DEG C, start pressure release, temperature comes out of the stove after being down to room temperature；
8th step, opens mould and recontour.
Beneficial effects of the present invention are：Production efficiency is improve, the generation of waste product is reduced, behaviour does simple, reduces life
Cost is produced, product quality is improve.
