Specific embodiment
Fig. 1 and Fig. 2 illustrate the activating mold core rod vertical view partly that tire processing sulfidation is used, and mainly are made up of the patrix 1 of annular, counterdie 2 and 10 fan-shaped pattern blocks 3 of annular.Patrix 1 is fixed on one can be along the loam cake below that axially moves up and down, and loam cake drive patrix 1 moves up when demoulding state, moves down during matched moulds.Counterdie 2 is fixed on the base.Each pattern block 3 is fixed on the slide block, and along moving radially, pattern block 3 radially outwards moves each pattern block 3 separately when demoulding state, moves inward simultaneously during matched moulds under the drive of sliding seat.Patrix 1, counterdie 2 and each pattern block 3 are worked in coordination with and are surrounded an annular die cavity 4 during the matched moulds state.During the production and processing tire, green tyre is placed in this annular die cavity 4, carries out first cure under pressure and high temperature.
As shown in Figure 3 and Figure 4, on the composition surface of pattern block 3 and patrix 1, excessive glue groove 5 is arranged, on the composition surface of pattern block 3 and counterdie 2 excessive glue groove 6 is arranged.Composition surface between pattern block 3 also can increase by an excessive glue groove 7 again.In making processing tire process, when the closing precision variation, cause excessive glue with regard to the slit having occurred between patrix and the pattern block, between pattern block and the counterdie or the composition surface between the pattern block, excessive rubber can flow into the glue groove 5 that overflows, overflow glue groove 6 and/or excessive glue groove 7, forms thick rubber strip and is convenient to removing.Excessive glue groove 5, excessive glue groove 6 and excessive glue groove 7 preferably are arranged on the position near die cavity 4 as far as possible, so that the thin film that may generate between die cavity 4 and excessive glue groove 5 is as far as possible little, prevent that thin film from coming off in die cavity 4, also be convenient on finished tire, remove the rubber strip that the glue groove that overflows forms.
