Core inner, upper mold core can move up and down, and during die mould, the first compression fit face is formed between upper mold core and middle mold core；Institute
Stating lower mold core is disc structure, and the lower mold core die shank being arranged by its lower end is fixed in lower template, in lower mold core external cylindrical surface
Upper setting during die mould, is formed for realizing the annular groove of lower mold core axial elastic deformation between lower mold core and middle mold core
Second compression fit face forms third compression fit face between lower mold core and upper mold core.
Above-mentioned sealing rubber ring curing forming mold, the annular groove are wedge section structure.
Above-mentioned sealing rubber ring curing forming mold is arranged on second compression fit face, third compression fit face and uses
In the waste containment chamber for receiving vulcanization clout.
The utility model be a kind of sealing rubber ring curing forming mold, it be arranged on lower mold core external cylindrical surface for realizing
The annular groove of lower mold core axial elastic deformation, during die mould, lower template drives lower mold core to move upwards, first in upper mold core
The first compression fit face is formed between middle mold core, as lower template, lower mold core continue up, in lower mold core and middle mold core
Between form the second compression fit face, then middle mold core be applied to lower mold core pressure effect under, lower mold core edge produce
Raw flexible deformation, forms third compression fit face between lower mold core and upper mold core.It can be seen that the utility model solves sulphur
The problem of changing three groups of compression fit face collective effects of upper mold core, middle mold core and lower mold core in mold, has reached reduction sealant
The manufacturing cost of circle, the purpose for improving sealing rubber ring product quality.
