Description

타이어의 가류 금형Vulcanization Mold of Tire

본 고안은 타이어의 가류 금형에 관한 것으로서, 더욱 상세하게는 가류시 타이어와 금형사이에 존재하는 공기를 용이하게 배출하며 공기 배출구로 인하여 타이어에 식출이나 자국이 생기지 아니하게 한 가류금형을 제공하기 위한 것이다.The present invention relates to a vulcanization mold of a tire, and more particularly, to provide a vulcanization mold which easily discharges air existing between the tire and the mold during vulcanization and does not cause extraction or marks on the tire due to the air outlet. will be.

브라더를 팽창시켜 그린타이어를 가류금형의 내부에 밀착시키려면 그린타이어와 가류금형 사이에 공기가 있어서는 아니된다. 따라서 브라더의 팽창에 따른 그린타이어의 금형 내벽에의 밀착은 필연적으로 공기의 배출을 필요로 한다. 그리하여 종래에는 금형에 통공을 설치하므로서 통공을 통하여 공기가 배출되게 하였던 바, 이러한 통공으로는 공기만이 배출되는 것이 아니라 고무마저 배출되어 타이어의 표면에 무수한 식출이 생기게 마련이었다. 그리하여 공기만이 배출되고 고무는 배출되지 아니하게 하는 밸브가 안출되기에 이르렀다.(본 출원인의 실용신안등록제 58621호; 공고번호 제91-2513호) 그러나 이와같이 공기 배출변을 장착한 가류 금형에 있어서는 공기 배출변의 작용 부전의 염려가 있으며 또한 공기 배출변 자체가 타이어에 흠을 형성시키는 결점이 있었다.There should be no air between the green tire and the vulcanizing mold to inflate the brother to squeeze the green tire to the inside of the vulcanizing mold. Therefore, the close contact of the green tire to the mold inner wall due to the expansion of the brother inevitably requires the discharge of air. Thus, in the related art, air was discharged through the through hole by installing a through hole in the mold. The air not only discharged through the through hole, but also the rubber was discharged, resulting in countless extraction on the surface of the tire. As a result, a valve was released, which allowed only air to be discharged and rubber not to be discharged. (Utility Model Registration No. 58621 of the Applicant; Publication No. 91-2513) However, in a vulcanizing mold equipped with an air discharge valve as described above. There is a risk of malfunction of the air outlet valve and there is a drawback that the air outlet valve itself forms a flaw in the tire.

본 고안은 타이어 가류 금형에 있어서의 위와 같은 문제점을 해결하여 공기의 배출을 원활히 함과 동시에 타이어와 금형사이의 공기 배출 작용 부전의 염려가 없게할 뿐 아니라, 타이어에 식출 등의 흠이 발생되지 아니하게 하고, 나아가 금형에 있어서의 트레드 부분을 금형 본체와 별도로 분리 형성시키되 분리된 트레드 부분 금형을 또한 다수개로 분할 형성시키므로서, 트레드의 디자인만을 변경시키기가 용이하도록 하여서된 금형을 제공하기 위한 것인 바, 이와같은 본 고안을 첨부된 도면에 의하여 설명하면 다음과 같다.The present invention solves the above problems in the tire vulcanization mold to facilitate the discharge of air and to avoid the possibility of impaired air discharge between the tire and the mold. Further, to provide a mold by separating the tread portion in the mold separately from the mold main body, but also by separately forming a plurality of separated tread portion molds, so as to easily change only the design of the tread. Bar, this invention is described by the accompanying drawings as follows.

금형 본체(1)와 트레드금형부(2)를 별도로 형성시켜서 된 통상의 것에 있어서, 트레드 금형부(2)를 다수개로 분리된 분할체(21,22,23,24,.....)의 결합으로 구성시키며, 각개의 분할체(21,22,23,24,.....)는 이웃하는 분할체(21,22,23,24,......)와의 접면부(31,32,33,34,....)와 이격부(41,42,43,44,.....)를 가지며, 각개의 분할체(21,22,23,24,.....)의 접면부(31,32,33,34,...)는 이웃하는 분할체(21,22,23,24.,,,,)의 접면부(31,32,33,34,...)와 밀접하게 접하여지나 각개의 분할체(21,22,23,24,....)의 이격부(41,42,43,44,....)는 이웃하는 분할체(21,22,23,24,.....)의 이격부(41,42,43,44,....)와 간격을 이루며 이러한 간격은 공간(5)을 형성시키게 된다. 공간(5)의 폭은 0.02∼0.08mm의 크기로 형성시키므로서 이러한 공간(5)을 통하여 공기는 배출되나 고무입자 등은 유입되지 아니하도록 형성시킨다. 물론 공간(5)는 금형 밖의 외부와 연통되어야 한다. 각개의 분할체(21,22,23,24,....)의 이격부(41,42,43,44,....)와 이에 이웃하는 분할체(21,22,23,24,.....)의 이격부(41,42,43,44,....)사이에 간격을 형성시킴에 있어서는 양측을 각각 0.01∼0.04mm씩 동일한 공간부를 가지게 형성시킬 수도 있으나, 일측에만 공간을 형성시킬 수도 있다.In the ordinary thing formed by separately forming the mold main body 1 and the tread mold part 2, the tread mold part 2 is divided into a plurality of divided bodies 21, 22, 23, 24, .....) Each partition (21,22,23,24, .....) is a contact portion with neighboring partitions (21,22,23,24, ......). 31, 32, 33, 34, ....) and spacings (41, 42, 43, 44, .....), each partition 21, 22, 23, 24, ... The contact portions 31, 32, 33, 34,... Of the contact portions are the contact portions 31, 32, 33, 34, of the neighboring partitions 21, 22, 23, 24. ..., but closely adjacent to each other (21, 22, 23, 24, ...), the separation portion (41, 42, 43, 44, ...) of the adjacent partition ( 21, 22, 23, 24, ....) is spaced apart from the space (41, 42, 43, 44, ...) of the space that forms the space (5). Since the width of the space 5 is formed in a size of 0.02 to 0.08 mm, air is discharged through the space 5, but rubber particles and the like are not introduced. The space 5 must, of course, communicate with the outside of the mold. Spacers 41, 42, 43, 44,... Of the respective partitions 21, 22, 23, 24,... And neighboring partitions 21, 22, 23, 24,. In forming a gap between the spaced parts 41, 42, 43, 44, .. of the .....), both sides may be formed to have the same space by 0.01 to 0.04mm, respectively, It can also form a space.

이상에서와 같이 구성된 본 고안은 트레드금형부를 본체와 분리 형성시켰으므로, 트레드금형부만을 달리 형성시키므로서 하나의 금형으로써, 다양한 형태의 트레 부분을 가지는 타이어를 성형시킬 수 있는데다가, 별도의 공기 배출 장치를 설치하지 아니하면서도 식출의 염려가 없이 완벽한 공기 배출 작용을 실현시킬 수 있으며, 공기 배출로 인하여 생길 수 있는 어떠한 흠도 타이어에 생기지 아니하게 하여 타이어의 품위를 크게 향상시킬 수 있게 하는 효과가 있다.Since the present invention configured as described above is formed separately from the main body of the tread mold, it is possible to form a tire having various types of tread portion with one mold by forming only the tread mold portion differently, and separate air discharge It is possible to realize perfect air bleeding without worrying about extraction without installing device, and it is effective to greatly improve the quality of the tire by not causing any flaw in the tire to be caused by air bleeding. .
