Definitions
- the present invention relates to, for example, a tire vulcanizing mold suitable for vulcanizing an off-the-road heavy-duty pneumatic tire belonging to the category of construction vehicles, and a pneumatic tire vulcanized thereby.
- the vulcanization of raw tires, especially the tread portion is performed by a plurality of sector-molds that are displaced in the radial direction of the tire, and the inner surface of the sector-mold is used.
- the present invention proposes a technique for preventing damage, breakage, and the like of the tread molding protrusion and the land formed on the tread.
- the heat generated in the central area of the tread can be suppressed low, and the heat generated in the central area of the tread can be increased based on the fact that the narrow walls of the narrow grooves are separated from each other outside the contact area. As a result, thermal deterioration of the tread central region can be advantageously prevented.
- each sector-one mold should be attached to the tread of the raw tire, When piercing in the radial direction of the tire, especially if the projection is prone to bending, breakage, etc., it is likely to be thin, and the projection for forming the narrow groove is likely to be bent.
- each sector mold is expanded and displaced to separate them from the vulcanized tire, and the mold is pierced into the tread tread surface in the tire radial direction.
- the protruding portion for forming the narrow groove is easily deformed due to a large pull-out resistance from the vulcanized and hardened tread, and the land portion of the tread is easily damaged by the protruding portion.
- An object of the present invention is to solve such problems of the prior art, and an object of the present invention is to use a sector-one mold for a tread portion of a large heavy load tire.
- the narrow and deep grooves shall be formed smoothly and reliably on the tread tread surface without damage or breakage of the groove forming projections of the sector-one mold and the tread land.
- the tire vulcanizing mold according to the present invention is arranged at a predetermined circumferential pitch, and is displaced synchronously with each other in the expanding / contracting direction to vulcanize the tread portion of the tire. It has a plurality of sector molds to be applied, and the inner surface of each sector mold The projecting direction of the groove-forming projection formed on the tread tread surface from the inner surface of the sector-mold is made substantially parallel to the displacement direction of each sector-mold.
- the displacement of a plurality of sector-molds is performed radially with respect to the center of the space defined by the sector-molds.
- the projecting direction of the protruding groove forming protrusion was set in the center direction of the section space to form a groove facing inward in the radial direction of the tire on the tread surface of the product tire.
- this angle difference is large when the distance from the center position of the inner surface of the sector-to-mold is large.
- the angle difference between the displacement direction of the sector-one mold and the projection direction of the groove-forming protrusion is determined by vulcanizing and molding each sector-mold with the above-mentioned radial mold.
- the diameter is reduced in the direction, the resistance of the groove-forming protrusion to the raw tire tread increases, so when the angle difference is large, the groove-forming protrusion is bent. There is a possibility that damage such as force S may occur, and this is
- the mold protrusion having a small thickness and a long protrusion length which contributes to the formation of a groove on the tread tread surface, has a groove in the tread circumferential direction.
- it is provided so as to protrude almost parallel to the displacement direction of the sector-mould, which is different from that extending in the tread width direction.
- the piercing resistance and the withdrawal resistance acting on each mold protrusion can be greatly reduced, and as a result, damage and breakage of the mold protrusion and the land formed on the tread of the tread are effective. Will be prevented.
- the displacement direction of each sector-mold is defined by a radial line segment connecting the inner surface of the sector-mold and the center of the space surrounded by each sector-mold in consideration of the three-dimensional shape. If it is the direction, a groove is formed in the tread tread that extends in any direction. In doing so, it is possible to more sufficiently protect the mold projections and the like.
- the present invention is particularly effective when the protrusion length of each mold protrusion from the inner surface of the mold is in the range of 0 to 180 mm.
- the protrusion length is less than 40 mm
- the influence of the angle difference between the displacement direction of the sector-to-mold and the protrusion direction of the mold protrusion is relatively small.
- the extremely thin mold protrusion of the mold has the same displacement direction of the mold and the protrusion direction of the protrusion, and because of the low strength of the protrusion, it can ensure smooth piercing and the like. It becomes difficult.
- each circumferential groove is formed in each sector-one mold and butt-joined in a zigzag shape in the circumferential direction.
- the protruding direction of the protrusion at the contact position of the mutually adjacent sector-mold is defined by the intersection of the circumferential line segment connecting the center of the inner surface of each sector-mold and the contact edge of the sector-mold.
- the direction is parallel to the adjustment line connecting the center of the space surrounded by each sector-mold, and the direction of projection of these projections is increased as the distance from the contact edge position of the sector-mold increases. Gradually approach the displacement direction of one sector.
- the projecting direction of each projection coincides with the displacement direction of the sector one mold at a position separated from the mutual contact position of the sector one mold by 50 mm or more along the ridgeline of the projection. Let it.
- the circumferential groove that continues in a zigzag shape in the circumferential direction on the tread tread surface has a circumferentially extending component and a tread widthwise extending component.
- the projecting direction of the mold protrusions is the displacement direction of the sector-mold in the cross section in the width direction, and the projecting direction is Since the direction is common to all the sectors and molds, it is not necessary to adjust the protruding direction of the mold protrusion between the sectors and molds adjacent to each other for the circumferentially extending component.
- the protruding direction of the mold protruding portion is seen in the circumferential cross section of each individual sector and the mold inner surface. Therefore, the direction of projection of each projection is shifted by an amount equivalent to the circumferential pitch of each sector and mold. Therefore, with respect to the component extending in the width direction, it is necessary to adjust the projecting direction of the mold protrusion between the adjacent sectors and molds.
- the zigzag circumferential groove formed on the tread surface will continue in the circumferential direction on the tread surface at the abutment part of the sector-mold, but will end apart from each other in the circumferential direction at other parts. Therefore, it is impossible to ensure the continuity of the circumferential groove.
- the projecting direction of the mold protrusion at the contact position of the sector and the mold to avoid the occurrence of force and squealing is made parallel to the adjustment line described above. It is possible to butt-join the entire protrusions between the adjoining sectors and molds, while on the other hand, as the protrusion directions of the protrusions move away from the contact positions of both sectors and molds,
- the displacement direction of the sector-mold should be gradually approached to the direction of expansion / contraction of the sector-mold, and more preferably, the projecting direction of the mold-projection should be at least 50 mm away from the contact position along the ridgeline of the projection. In this way, the zigzag circumferential grooves can be smoothly and reliably formed continuously, and the risk of damage to the mold projections and the like can be advantageously eliminated.
- the reason that the projecting direction of the mold protrusions is made to coincide with the displacement direction of one sector at a position separated by 50 mm or more is that if it is less than 50 mm, an unnatural appearance appears and the Is a concern.
- the zigzag groove of the tread tread is opened to a wide lug groove extending to the tread side region, the zigzag groove is measured along the ridgeline of the protrusion from the mutual contact position of the sector and the mold. If the protrusion is continuous with the large lug groove forming protrusion at a distance of less than 50 mm, the protrusion direction of the protrusion should be flat with the adjustment line segment until the continuous position to the large protrusion. In this case, it is possible to protect the molding projection with a high rigidity of the large projection, such as damage.
- the number of pitches of the sector-to-mold over the entire circumference in other words, the number of arranged sectors-to-mold itself is 1245. Les ,. [0025] That is, when the number of the molds is less than 12, the influence on the roundness, such as mold processing accuracy, becomes too large, and the tire radial direction and the sector-to-mold expansion / contraction direction at both circumferential ends of the sector-mold. When the angle difference exceeds 15 °, the effect on tire performance may not be negligible.On the other hand, when the angle exceeds 45, the mold cost becomes too high and handling workability etc. There is a tendency that the decline of the inevitable.
- the pneumatic tire according to the present invention is vulcanized by any of the tire vulcanizing dies described above.
- various grooves formed on the tread tread surface in particular, The groove can be narrow and the groove can be made appropriate without damage, etc., and the function of the groove body can be sufficiently exhibited in those grooves.

- PP indicates the pattern pitch of the tread pattern.
- Such a tread pattern is arranged at a predetermined circumferential pitch, and a plurality of sectors each of which is displaced in synchronization with each other in a synchronized manner are vulcanized.
- the direction of protrusion of each of the protrusions from the inner surface of the mold should be substantially parallel to the direction of expansion and contraction displacement of each sector-to-mold.
- FIG. 3 a cross-sectional view of one sector and one mold is shown in FIG.
- the mold protrusion 21 of the mold is formed by the direction X of expansion and contraction of the sector 22 and, more precisely, the center O of the mold inner surface 23 and each sector.
- 0 is formed in a direction substantially parallel to a radial line segment R connecting the center ⁇ of the space surrounded by the single mold 22. It becomes common about.
- the circumferential linear groove 4 formed in this manner is formed on the mold inner surface 23 by a normal line indicated by a virtual line in the figure, in other words, extends in the cross section of the circumferential linear groove according to the conventional technique.
- the groove bottom portion is located on the side of the tread as compared to the direction, this is not a particular disadvantage in this type of tire.
- the mold protrusions 21 are provided in all the sector-molds 22 as shown in the figure.
- each protrusion 21 is inserted into the raw tire tread and the sector.
- FIG. 4 shows a mold protrusion for forming a width direction groove 5 for providing communication between the two circumferential linear grooves 4 formed in this manner.
- the projecting direction of each mold protrusion 24 from the mold inner surface 23 is defined by the center O of the mold inner surface 23 and the sector.
- the extending direction of the radial line segment R connecting the center O of the space surrounded by the one mold 22 is preferably set to a direction substantially parallel to the mold displacement direction X.
- the relative displacement directions of the circumferentially adjacent sector-molds 22 differ by an angle corresponding to the circumferential pitch MP of the sector-molds 22.
- the same is true for the protrusions 24 of the sector-to-mold 22 of this type.However, such a difference between the sectors-to-mold 22 also indicates that the width formed on the tread tread surface is limited as long as the mold pitch number is 12 or more. There is no particular disadvantage to the operation of the directional groove 5.
- the mold projection 24 receives only a very small resistance in the expansion and contraction displacement of each sector mold 22, so that the Even in the case where the thickness is small and the protruding length is long, it is possible to effectively eliminate the possibility that the protruding portion 24 or the like may be damaged.

- each groove 7 and 8 has a groove width of 2 to 20 mm and a depth of 40 to 180 mm, and the inclined groove 8 extends beyond the circumferential pitch MP of the sector-to-mold 22. It does not exist.
- the total number of the circumferential pitches MP of the sector-to-mold 22 over the entire circumference is 1245, and the total number of pattern pitches PP is 2545. It is preferable that the number be one to three. The same is true for the tread pattern shown in FIG.
- the zigzag groove 7 unlike the circumferential linear groove 4, has not only a circumferentially extending component but also a tread widthwise extending component. Therefore, if the projecting direction of the mold projection for forming the zigzag groove 7 is specified to be unique to each sector-to-mold 22 and is specified in a direction parallel to the displacement direction of the sector-to-mold 22, the mutual At the contact position of the two sectors and the mold 22 adjacent to each other, as schematically illustrated in a circumferential cross-sectional view in FIG.
- each of the mold projections for forming the point C portion of the zigzag groove 7 shown in FIG. 7 protrudes over the adjustment line segment R as shown in FIG. As a result, the continuity of the zigzag groove 7 in the circumferential direction is secured.
- the protrusions of the respective protrusions are required.
- the protrusion direction of the protrusion is As shown schematically in Fig. 8, the respective mold protrusions 24-1 and 24-2 are gently curved from the butt joint position corresponding to the point C, as shown in Fig. 8. Gradually approach the direction parallel to the mold displacement direction via 25-1 and 25-2, and set the required parallel direction at each of points D and E.
- the protruding direction force of the Monoredo protrusions 24-1 and 24-2 is set to be exactly parallel to the displacement direction of each sector one mold 22-1 and 22-2 along the protrusion ridge line.
- the reason why it is set to 50 mm or more is to remove the discomfort in appearance, taking into account the maximum amount of twist of the mold protrusion in large tires.

- the groove force extends in the depth direction in a direction substantially parallel to the above-described adjustment line connecting the intersection point O and the center of space.
- the included angle with the connected adjustment line segment (see “ ⁇ ” in Fig. 6) is (360 ° ⁇ mold pitch number / 2). According to the mold pitch number (18) in Table 1, the angle is calculated as 10 °. Therefore, at the point F, the zigzag groove is parallel to the radial line segment in the depth direction. And at point H, if both extend exactly in the direction parallel to the adjustment line, the included angle of the extension line in the depth direction at each of those points (" ⁇ " in FIG. 6). (See ”)", which was also 10 °, which was 7.2 ° in the zigzag groove arrangement.

If the ridgeline distance is shorter than 50mm and the lug groove is wide at point I, adjust the extension of the groove in the depth direction without adjusting between H and I. It is also possible to maintain the same direction as the projecting direction at point H, which is parallel to the line segment.
- a block row defined by narrow grooves is formed in the central region of the tread.
- the required continuity can be reliably provided to the groove extending in a direction obliquely intersecting the contact edge of the sector-to-mold, so that the degree of freedom in designing the tread pattern is greatly increased.
- the adoption of a tread pattern having a complicated configuration can be sufficiently permitted.
