Description

타이어 가류금형{Vulcanizing mold for tire}Vulcanizing mold for tire

본 고안은 타이어 가류금형에 관한 것으로서, 더욱 상세하게는 다수개로 분할 형성되는 트래드금형의 접면 형상을 개선하여 가류시 트래드금형의 움직임을 억제시키고, 식출의 발생을 방지할 수 있게 하는 타이어 가류금형에 관한 것이다.The present invention relates to a tire vulcanization mold, and more particularly, to a tire vulcanization mold which improves the contact shape of the tread mold which is divided into a plurality, thereby suppressing the movement of the tread mold during vulcanization and preventing occurrence of extraction. It is about.

일반적으로 그린 타이어를 가류시키는 가류금형은 첨부된 도면 도 1 에 도시되는 바와 같이, 톱플레이트(2)의 주연에 트레드금형(5)이 결합된 세그먼트(Segment)(4)가 좌우로 슬라이드 가능하게 설치되고, 상기 세그먼트(4)의 외측에는 플래튼(Platen)(1)에 결합된 아웃터링(3)이 설치되어 구성된다.In general, a vulcanization mold for vulcanizing a green tire is provided with a segment 4 having a tread mold 5 coupled to a circumference of the top plate 2 so as to slide left and right as shown in FIG. 1. It is provided, and the outer ring 3 is coupled to the platen (1) on the outside of the segment (4).

이와 같은 가류금형는 승강장치에 플래튼(1)이 승하강되면서 아웃터링(3)의 경사면이 세그먼트의 경사면과 접촉하면서 세그먼트(4)를 안쪽으로 밀어주어 다수로 분할된 트레드금형(5)을 밀착시켜 그린 타이어를 가류시키는 것이다.Such a vulcanizing mold pushes the segment 4 inward while the platen 1 is raised and lowered on the elevating device while the inclined surface of the outer ring 3 comes into contact with the inclined surface of the segment, thereby closely contacting the tread mold 5 divided into a plurality. To cure the green tires.

첨부된 도면 도 2 는 종래의 트래드금형의 발췌 도시한 사시도이다.2 is a perspective view showing an extract of a conventional tread mold.

도 2 에 도시되는 바와 같이, 종래의 트래드금형은 분할형성된 각각의 트래드금형 접면이 평활한면으로 형성되어 그린 타이어의 가류시 브라더의 팽창되는 힘에 의해 트래드금형의 접면부가 서로 어긋날 수 있다.As shown in FIG. 2, the conventional tread mold has a divided tread mold contact surface having a smooth surface, and the tread mold contact portions may be shifted from each other by the expanding force of the brother when the green tire is vulcanized.

트래드금형의 접면부에 단차가 발생되면 가류되는 타이어에 식출이 발생되어 불량처리되는 문제점이 있다.If a step occurs in the contact portion of the tread mold, there is a problem that the extraction is generated in the vulcanized tire is poorly processed.

본 고안은 상기와 같은 종래의 문제점을 해결하기 위한 것으로서, 본 고안은 다수개로 분할 형성되는 트래드금형의 접면 형상을 개선하여 가류시 트래드금형의 움직임을 억제시키고, 식출의 발생을 방지할 수 있게 하는 타이어 가류금형을 제공함에 그 목적이 있다.The present invention is to solve the conventional problems as described above, the present invention is to improve the contact shape of the tread mold is divided into a plurality to suppress the movement of the tread mold during vulcanization, it is possible to prevent the occurrence of extraction The object is to provide a tire vulcanization mold.

본 고안은 상기와 같은 목적을 달성하기 위하여 다음과 같이 구성된다. 즉, 본 고안은 톱플레이트에 세그먼트(Segment)가 좌우로 슬라이드 가능하게 설치되고, 상기 세그먼트의 내측에 분할형성된 다수의 트래드금형이 설치되고, 상기 세그먼트의 외측에는 플래튼(Platen)에 결합된 아웃터링이 설치되어 구성되는 타이어 가류금형에 있어서, 다수개로 분할형성되는 트래드금형의 접면부가 서로 맞닺는 접면부와 걸리어질 수 있도록 요철부를 대응되게 형성시켜 구성되는 것에 특징을 둔 것이다.The present invention is configured as follows to achieve the above object. That is, the present invention is a segment (Segment) is slidably installed to the left and right on the top plate, a plurality of tread molds are formed on the inside of the segment is installed, the outer side of the segment coupled to the platen (Platen) out In the tire vulcanization mold, which is formed by installing a turing, the contact portion of the tread mold, which is divided into a plurality, is formed by correspondingly forming an uneven portion so as to be caught with a contact portion that meets each other.

첨부된 도면 도 3 는 본 고안에 따른 트래드금형을 발췌 도시한 단면도이고, 도 4 는 본 고안의 다른 실시 예를 도시한 단면도이다.3 is a cross-sectional view showing an extract of the tread mold according to the present invention, Figure 4 is a cross-sectional view showing another embodiment of the present invention.

도 3 및 도 4 에 도시되는 바와 같이, 본 고안은 톱플레이트(2)에 세그먼트(4)가 좌우로 슬라이드 가능하게 설치되고, 상기 세그먼트(4)의 내측에 분할형성된 다수의 트래드금형(5)이 설치되고, 상기 세그먼트(4)의 외측에는 플래튼(Platen)(1)에 결합된 아웃터링(3)이 설치되는 타이어 가류금형에 있어서, 다수개로 분할형성되는 트래드금형(5)의 접면부(50)가 서로 맞닺는 접면부와 걸리어질 수 있도록 요철부(55)를 대응되게 형성시켜 구성되는 것이다.As shown in Figures 3 and 4, the present invention is a segment 4 is slidably installed on the top plate 2 to the left and right, and the plurality of tread molds 5 formed in the inner part of the segment (4) In the tire vulcanization mold in which the outer ring 3 coupled to the platen 1 is installed on the outer side of the segment 4, the contact portion of the tread mold 5 divided into a plurality. The concave-convex portion 55 is formed to correspond to the contact portion 50 to be in contact with each other.

상기 요철부(55)는 톱니형상으로 형성시킬 수도 있고, 웨이브형상으로 형성시킬 수도 있는 것이다.The uneven portion 55 may be formed in a sawtooth shape or may be formed in a wave shape.

이와 같이 구성되는 본 고안은 그린 타이어의 가류시 트래드금형의 접면부가 요철부에 의해 근접한 트래드금형과 견고하게 결합됨에 따라 브라더의 팽창력에 의해 트래드금형이 밀려 접면부에서 발생되는 단차를 억제시킬 수 있는 것이다.The present invention configured as described above can firmly bind the tread mold when the green tire is vulcanized with the tread mold adjacent by the uneven portion, so that the step of the tread mold can be suppressed due to the expansion force of the brother, thereby suppressing the step difference generated at the fold portion. will be.

이에 따라 금형의 접면부에서 빈번하게 발생되는 식출을 방지시킬 수 있는 것이다.As a result, it is possible to prevent extraction that occurs frequently at the contact portion of the mold.

본 고안은 전술한 실시 예에 한정되지 않고 본 고안의 기술사상이 허용하는 범위 내에서 다양하게 변형하여 실시할 수가 있다.The present invention is not limited to the above-described embodiments, and various modifications can be made within the range permitted by the technical idea of the present invention.

이상에서와 같이 본 고안에 따르면 타이어의 가류시 트래드금형의 움직임을 억제시키고, 트래드금형의 접면부사이에서의 식출 발생을 방지할 수 있는 효과가 있는 것이다.As described above, according to the present invention, it is possible to suppress the movement of the tread mold during the vulcanization of the tire and to prevent the extraction of the tread mold between the contact portions.
