Description
Technical Field
The utility model relates to the technical field of dies, in particular to a sectional tire pattern forming die.
Background
The existing tire pattern forming die comprises the following components: in the tire vulcanization production process, the annular steel sheets of the upper and lower mold locking structures are easy to deform under stress, and the circumferential or radial displacement phenomenon of the tire pattern blocks occurs, so that the integrity of the tire pattern blocks is damaged, and the wear resistance of the tire is also influenced.
In the utility model patent with the publication number of CN216682915U, a tire mold structure is disclosed, which comprises a mold jacket, a mold cavity, a cavity, an air inlet groove and a tire pattern block manufacturing area, wherein the mold cavity is positioned in the mold jacket and communicated with the cavity through the air inlet groove, the tire pattern block manufacturing area is distributed at the outer edge of the mold cavity, the tire mold structure also comprises a ring-shaped steel sheet, the ring-shaped steel sheet is positioned in the mold jacket and distributed at the outer side of the tire pattern block manufacturing area in an array manner, the mold jacket comprises an upper mold and a lower mold, the upper mold is matched with the lower mold to form a mold closing position, a central pattern block manufacturing area is arranged in the tire pattern block manufacturing area, the width of the central pattern block manufacturing area is a, the width from the edge of the upper mold to the mold closing position is b, and the width from the edge of the lower mold to the mold closing position is c, |b-c|=a.
The patent also adopts a mode based on an upper die and a lower die to realize die opening, adopts the deviation dislocation design of the upper die and the lower die, and avoids the manufacturing area of the central pattern block of the die even if the annular steel sheet is deformed and shifted in the using process of the patent, and the position of a die clamping opening where the deformation and the shift occur is positioned in the groove between the pattern blocks of the tire without influencing the integrity of the central pattern block of the tire.
However, due to the mold opening mode (the mold opening mode is divided into an upper mold and a lower mold), the tire with simple pattern lines or specific lines can be manufactured on the pattern line design, the pattern lines, especially complex pattern blocks, are easily damaged by mold opening, once the tire has the mold sticking phenomenon during upper and lower vulcanization mold opening, the pattern lines are easily scratched during mold opening, and the ring-shaped steel sheets are adopted in the patent, are positioned in the mold jacket and distributed outside the tire pattern block manufacturing area in an array manner, so that the mold opening is not easy to operate and has low efficiency.
Disclosure of Invention
The utility model aims to provide a sectional tire pattern forming die, which has the advantages that the structure is simpler by changing the die opening mode, patterns with unique and complex patterns can be manufactured, the patterns are not required to be worried about the patterns which are easily damaged by pulling out the patterns up and down after being complex, the die opening operation is simple, the die opening efficiency is improved, and the labor intensity is reduced.
In order to achieve the above purpose, the present utility model is realized by the following technical scheme: the utility model provides a sectional type tire decorative pattern forming die, includes the mould base plane, be provided with a plurality of groups of tracks on the mould base plane, still be provided with a base on the base plane and hold in the palm, be provided with annular mould on the base holds in the palm, be provided with tire decorative pattern line on the annular mould inner wall, be provided with slide rail and annular mould piece outer wall both ends on the annular mould outer wall still are provided with the hasp, the track cooperation that sets up on slide rail and the base plane is installed, annular mould is formed by a plurality of sections annular mould piece end to end concatenation, connect through the hasp between the adjacent annular mould piece.
In order to position and mount the rim and the base support with corresponding sizes, a positioning ring is further arranged in the base support, and when the positioning device is used, the rim and the positioning ring with corresponding sizes are matched and placed, so that positioning is realized.
Because of the continuity and the sequency of different tire patterns, for the simple splicing, the operation is convenient, and the annular die is formed by splicing the ends of three sections of annular die blocks.
Compared with the prior art, the utility model has the following beneficial effects: according to the utility model, the upper die and the lower die are changed into horizontal die opening by changing the die opening mode (the die is separated from the tire by only pulling the sliding rail of the annular die block at the corresponding position), so that the defect that the pattern lines are easily damaged after the pattern is complicated is avoided, the die opening operation is simple, the die opening efficiency is improved, and the labor intensity is reduced.

Description of the embodiments
The following description of the optimized specific technical scheme refers to the accompanying drawings and the specific embodiments:
as shown in fig. 1-2, a sectional tire pattern forming mold comprises a mold base plane 1, a plurality of groups of rails 7 are arranged on the mold base plane 1, a base support 2 is further arranged on the mold base plane 1, an annular mold 4 is arranged on the base support 2, tire pattern lines are arranged on the inner wall of the annular mold 4, a sliding rail 5 is arranged on the outer wall of the annular mold 4, lock catches 6 are further arranged at two ends of the outer wall of the annular mold 4, the sliding rail 5 is matched with the rails 7 arranged on the mold base plane 1, the annular mold 4 is formed by splicing a plurality of sections of annular mold blocks in a head-tail mode, and adjacent annular mold blocks are connected through the lock catches 6.
In order to position and mount the rim and the base support with corresponding sizes, a positioning ring 3 is further arranged in the base support 2, and when the positioning device is used, the rim and the positioning ring with corresponding sizes are matched and placed, so that positioning is realized.
Because of the continuity and the sequence of different tire patterns, the annular mold 4 is formed by splicing three annular mold blocks for the sake of simple splicing and convenient operation.
