Abstract
The utility model relates to a structure with adjustable tire mould pre -compaction volume, including fit with a contraceptive ring, well die sleeve and connecting bolt, connecting bolt has the double thread, and lower end screw thread connection is on well die sleeve to it is fixed through lock nut, fit with a contraceptive ring and well die sleeve between connecting bolt on, the cover is equipped with spring and spring guide pin bushing the below of spring is equipped with the spacing bolt washer of spring, connecting bolt's upper end is passed and is fitted with a contraceptive ring and be connected with fitting with a contraceptive ring through adjusting nut. Adjustment pre -compaction volume only needs to adjust disc spring's pretightning force and height through the the tight regulation nut, can accomplish on the vulcanizer. Because the pre -compaction volume can be adjusted by optional size in the adjusting range, to compare with traditional increase gasket adjustment, the precision is higher, advantages such as easy operation.
Description
Technical field
The utility model relates to a kind of tire-mold precompressed amount adjustable structure, especially a kind of engineering vehicle radial tyre mould precompressed amount adjustable structure.
Background technology
Radial ply tyre moulds precompressed amount refers to mould under cold mould state after matched moulds, mold integral is lifted on experimental rig, again for several times certain moment of torsion external force is applied in 4 o'clock minutes to die sleeve in mould or pressed on ring circumference, the height average of die sleeve or pressed on ring and upper tops in finally measuring.The effect of precompressed amount is after mould matched moulds, applies certain centripetal force to pattern block, prevents from making pattern block outwards movement because of capsule inflating pressure during tyre vulcanization, if precompressed amount is inadequate, pattern block matched moulds is not in place, and glue limit will appear in tire.Glue limit not only affects the presentation quality of tire, and the serious dynamic balancing that also can affect tire.
The structure of conventional project tire-mold as shown in Figure 1 and Figure 2.The precompressed amount of common engineering vehicle tyre activating mold controls at 1-1.2mm, mould is after using after a while, because each parts wear, the precompressed amount of mould can reduce, when the glue limit of tire is relatively serious, need the precompressed amount readjusting mould to avoid the appearance of overlap.Conventional method increases pads at middle die sleeve or pressed on ring upper surface circumference 4 or 6 locked mode screw positions, by adjusting the thickness adjustment precompressed amount of pad, the spacer thickness that general mould factory uses has 0.3mm, 0.5mm and 1mm, then selects the combination of pad according to the precompressed amount of mould reality.But at every turn after activating mold under vulcanizer replacing, adjustment pad is also dismantled together, so need to often pay mould increase adjustment spacer thickness keep a record, next die-filling time according to record increase adjustment pad, this is relatively high to the management expectancy of mould; Structure shown in Fig. 2 also can increase adjustment pad at adjustment packing ring 2 place, way first pressed on ring is taken apart, the pad of desired thickness is increased according to actual needs on adjustment packing ring, then pressed on ring is reinstalled, this method need not repeat dismounting mode transfer pad, but need dismounting pressed on ring, operate cumbersome.
Summary of the invention
The purpose of this utility model is for above Problems existing, provides a kind of tire-mold precompressed amount adjustable structure more easily adjusting mould precompressed amount more accurately.
The utility model, comprise pressed on ring, middle die sleeve and connecting bolt, described connecting bolt has double thread, and lower end is threaded on middle die sleeve, and is fixed by lock nut; On connecting bolt between pressed on ring and middle die sleeve, be arranged with spring and spring guide thereof, in the below of described spring, be provided with spring retainer bolt washer; The upper end of connecting bolt is passed pressed on ring and is connected with pressed on ring by adjusting nut.
The utility model, described spring can be butterfly spring.
The utility model, tool has the following advantages:
1, precompressed amount can adjust by arbitrary dimension in adjusting range, and compared with adjusting with traditional increase pad, precision is higher.
2, after precompressed amount is adjusted, after loading and unloading mould from vulcanizer, precompressed amount remains unchanged at every turn.
3, adjust precompressed amount only need adjust butterfly spring pretightning force and height by degree of tightness adjusting nut, can complete on vulcanizer.Operate fairly simple.
Accompanying drawing explanation
Fig. 1, Fig. 2 are the structure principle chart of conventional project vehicle tyre mould, and Fig. 3-Fig. 4 is structure principle chart of the present utility model, and wherein Fig. 4 is partial enlarged drawing.
In figure, 1, pressed on ring; 2, mode transfer packing ring; 3, middle die sleeve; 4, gib block; 5, slide block; 6, on-slip pin; 7, base; 8, locating ring; 9, lower side panel; 10, pattern block; 11, epipleural; 12, upper cover; 13, lift block; 14, upper steel ring; 15, lower steel ring; 21, spring retainer bolt; 22, adjusting nut; 23, spring guide; 24, butterfly spring; 25, spring retainer bolt washer; 26, lock nut.
Detailed description of the invention
With reference to Fig. 3, Fig. 4, a kind of radial ply tyre moulds containing precompressed amount adjustable structure, form primarily of pressed on ring 1, middle die sleeve 3, gib block 4, slide block 5, on-slip pin 6, base 7, locating ring 8, lower side panel 9, pattern block 10, epipleural 11, upper cover 12 and lift block 13, between pressed on ring 1 and middle die sleeve 3, be provided with precompressed amount adjustable structure.Described precompressed amount adjustable structure comprises connecting bolt 21, and connecting bolt has double thread, and lower end is threaded on middle die sleeve 3, and is fixed by lock nut 26; On connecting bolt 21 between pressed on ring 1 and middle die sleeve 3, be arranged with butterfly spring 24 and spring guide 23 thereof, in the below of described butterfly spring 24, be provided with spring retainer bolt washer 25; The upper end of connecting bolt 21 is passed pressed on ring 1 and is connected with pressed on ring 1 by adjusting nut 22.
Its operation principle is the pretightning force and the height that are controlled butterfly spring 24 combination by the moment of torsion of adjustment adjusting nut 22, thus reaches the effect of adjustment precompressed amount.
