The specific embodiment
In Fig. 1, Fig. 2, Fig. 3, Fig. 4, the utility model comprises telescoping mechanism and transmission mechanism, and wherein, telescoping mechanism is mainly comprised of narrow drum watt telescoping mechanism and a wide drum watt telescoping mechanism.A narrow drum watt telescoping mechanism comprises: narrow drum watts 10, narrow drum watt support 9; A wide drum watt telescoping mechanism comprises: wide drum watt 1, wide drum watt support 18.Transmission mechanism comprises: piston rod 14, end cap 6, clamp ring 4, pedestal 13, position-arresting disk 15, narrow watt of side slide block 8, narrow watt of side guide 7, wide watt of side slide block 2, wide watt of side guide 3, wide watt of base slider 16, wide watt of bottom guide track 17, narrow watt of base slider 12, narrow watt of bottom guide track 11.End cap 6 is fixed with pedestal 13 one end, and be fixedly connected with piston rod 14 with connecting bolt 5 by clamp ring 4, on the lozenges of pedestal 13, be mounted alternately with narrow watt of side guide 7 and wide watt of side guide 3, narrow watt of side guide 7 coordinates with the narrow watt of side slide block 8 being fixed on narrow drum watt support 9, and wide watt of side guide 3 coordinates with the wide watt of side slide block 2 being fixed on wide drum watt support 18.
When piston rod 14 vertical lifts, pedestal 13 is with piston rod 14 motions, and by guide rail and coordinating of slide block driving radially breathing of telescoping mechanism, on piston rod 14, be set with position-arresting disk 15, position-arresting disk 15 and the fixing assembling of central authority base 20, on position-arresting disk 15 upper sides are circumferential, narrow watt of base slider 12 and wide watt of base slider 16 are alternately housed, coordinate with the narrow watt of bottom guide track 11 and the wide watt of bottom guide track 17 that are fixed on narrow drum watt support 9 and wide drum watt support 18 respectively, prevent that axial displacement from appearring in drum watt in telescopic process.
As shown in Figure 3, tyre vulcanization inner mold of the present utility model, wide drum watt 1 and narrow drum watts 10 be along circumferential alternative arrangements, when all drums are watt in distending position, the overall diameter of inner mold equals outline diameter in finished tire, and its outline curve is consistent with finished tire inner profile curve.
As shown in Figure 4, the curing bag on tire shaping vulcanizing machine central mechanism is replaced with to tyre vulcanization inner mold of the present utility model, under the driving of central authority piston rod 14, inner mold can be realized flexible.When vulcanizer is during in matched moulds state, inner mould presents distending form and coordinates with outer mold 23 fetus 19 is imposed to the required high pressure of sulfuration.
Adopt the tire curing concrete steps of the utility model:
1) dress tire: position-arresting disk 15 is apart from lower steel ring 21 certain altitudes, drum watt bottom does not interfere with lower steel ring 21 when guaranteeing mould breathing, and the utility model inner mold, in contraction state, will treat that cured tire base 19 is placed on sulfuration board simultaneously.
2) sizing: position-arresting disk 15 keeps motionless with central authority base 20, central authority piston rod 14 declines, pedestal 13 is with piston rod 14 motions, and by guide rail and coordinating of slide block driving radially distending of telescoping mechanism, when opening completely, wide drum watt 1 and narrow drum watts 10 stop action, now tire base 19 is propped up fixingly by drum watt, and central authority moves down subsequently, and inner mold is placed on lower steel ring 21 together with tire base 19.
3) matched moulds: as shown in Figure 4, vaporium is closed, and now outer mold upper cover 22 is pushed down clamp ring 4 upper surfaces, and centring machine structure carries out spacing, prevents between curing time that drum watt surface pressing is excessive and causes piston rod 14 to go up.
4) unload tire: vaporium is opened, cured tire is followed central authority and is moved on the whole, when departing from lower steel ring 21 completely, lower sidewall stops action, then position-arresting disk 15 keeps motionless with central authority base 20, on central authority piston rod 14, move, by driving guide rail and coordinating of slide block wide drum watt 1 and narrow drum watts 10 to be contracted in tyre bead diameter, now tire is taken off smoothly.
