Abstract
The utility model relates to the technical field of rubber molds, in particular to a tire two-half mold, which comprises a pattern block upper mold pattern block, a lower mold pattern block, a parting line and a chamfer angle; the entire tire block is circumferentially divided into two portions by a parting line: an upper mold block and a lower mold block; the edges of the upper mould pattern blocks on the parting line are chamfered, so that the problem that the pattern blocks fall off due to the fact that tread patterns are scratched after the tyre is ejected is avoided, and the product quality is guaranteed. According to the utility model, the chamfer is arranged at the edge of the upper die pattern block, so that the pattern block is effectively prevented from being scratched after the tire is taken out of the die, the defective rate is reduced, the structure is simple, and the processing is convenient.
Description
Technical Field
The utility model relates to the technical field of rubber molds, in particular to a tire two-half mold.
Background
With the development of the automobile industry, people have more and more demands on tires, and how to improve the production efficiency is the aim of each dry tire industry. The two half moulds of the semisteel tyre have lower cost and are widely applied to common tyre products. Because of the problem of the design of the two half molds, the parting line is designed at the center of the tread or at the upper position, and the pattern blocks at the parting line position are very sharp, the tread pattern is easily scratched in the production process, the pattern blocks fall off, the appearance quality of the tire is affected, and waste and defective products are generated.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art, and provides a two-half tire mold which can effectively ensure that pattern blocks are not scratched after the tire is ejected, so that the rate of defective products is reduced.
The technical scheme adopted for solving the technical problems is as follows:
a tire two-half mold comprises a pattern block upper mold pattern block, a lower mold pattern block, a parting line and a chamfer; the entire tire block is circumferentially divided into two portions by a parting line: an upper mold block and a lower mold block; the edges of the upper mould pattern blocks on the parting line are chamfered, so that the problem that the pattern blocks fall off due to the fact that tread patterns are scratched after the tyre is ejected is avoided, and the product quality is guaranteed.
Further, the chamfer is positioned at the edge of the upper die pattern block, and a circle of chamfer is circumferentially distributed.
Further, the chamfer is arc-shaped.
Further, the fillet radius of the chamfer is 0.8mm-1.5mm, such as 0.8mm, 0.9mm, 1.0mm, 1.2mm, 1.3mm, etc.
Further, the parting line is located between 0 and 15mm above the block in the transverse direction, such as 0.2mm, 1.0mm, 5.5mm, 6.0mm, 8.0mm, 12.5mm, 14.0mm, etc.
The utility model has the technical effects that:
compared with the prior art, the two-half tire mold has the advantages that the chamfer is arranged at the edge of the upper mold pattern block, so that the pattern block is not scratched after the tire is ejected, the defective rate is reduced, the structure is simple, and the processing is convenient.

1, an upper die pattern block; 2. a lower mold pattern block; 3. parting line; 4. chamfering.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present utility model more clear, the technical solutions in the embodiments of the present utility model are clearly and completely described below with reference to the accompanying drawings of the specification.
Example 1:
as shown in fig. 1 and 2, the present embodiment relates to a tire two-half mold including a block upper mold block 1, a lower mold block 2, a parting line 3, and a chamfer 4.
As shown in fig. 1, the entire tire block is circumferentially divided into two parts by a parting line 3: an upper mold block 1 and a lower mold block 2; the parting line 3 is horizontal to the ground in the radial direction.
As shown in fig. 2, the upper die block 1 is chamfered at the position of the parting line 3. The chamfer 4 is arc-shaped, is positioned at the edge of the upper die pattern block 1, and is circumferentially distributed for one circle, so that the problem that the pattern block is dropped due to the fact that a tread pattern is scratched after a tire is taken out of a die can be avoided.
As one of the embodiments, the fillet radius of the chamfer 4 is 0.8mm; the parting line 3 is positioned between 0.2mm above the block by taking the transverse direction as the center.
As another embodiment thereof, the fillet radius of the chamfer 4 is 1.0mm; the parting line 3 is positioned between 8.0mm above the transverse direction of the pattern block.
As another embodiment, the fillet radius of the chamfer 4 is 1.5mm; the parting line 3 is positioned between 15mm above the transverse direction of the pattern block.
As another embodiment, the fillet radius of the chamfer 4 is 1.2mm; the parting line 3 is positioned on the upper 6.0mm of the block in the transverse direction.
According to the utility model, the chamfer is arranged at the edge of the upper die pattern block 1, so that the pattern block is effectively prevented from being scratched after the tire is taken out of the die, and the waste and defective rate is greatly reduced. Simple structure and convenient processing.
The above embodiments are merely examples of the present utility model, and the scope of the present utility model is not limited to the above embodiments, and any suitable changes or modifications made by those skilled in the art, which are consistent with the claims of the present utility model, shall fall within the scope of the present utility model.
