본 발명은 자동차용 타이어를 가황하는 금형에 관한 것으로, 특히, 문자표지판설치부를 개량하여서 된 타이어 가황용 금형에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mold for vulcanizing automobile tires, and more particularly, to a tire vulcanizing mold obtained by improving a letter board mounting portion.

타이어에는 보통 생산시기를 표시하게 되는 바, 이러한 시기를 표시하기 위하여 금형에 생산시기를 표시하는 문자표지판을 부착하고 교환하게 된다. 금형에 부착 교환하는 문자표지판은 금형의 문자표지판설치부에 설치되며 종래의 금형에 있어서의 문자표지판설치부는 금형의 내측 타이어 성형부에 안쪽으로 경사진 턱을 가지는 홈을 형성시키고 이 홈에 주연이 구부러진 문자판을 끼우고 구부러진 문자판 주연을 펴서 홈에 문자표지판이 설치되도록 구성되어 있다.Tires are usually marked with the production time. To indicate these times, a letter board indicating the production time is attached to the mold and replaced. The letter board to be attached to and exchanged in the mold is installed in the letter plate mounting portion of the mold. In the conventional mold, the letter plate mounting portion forms a groove having an inclined jaw in the inner tire forming portion of the mold. The bent dial is fitted and the bent dial is stretched out so that the dial is installed in the groove.

그런데, 이러한 종래의 금형에 있어서는, 특히 문자표지판설치부가 상부금형에 설치되고 금형이 가류기에 설치되어 있으며 이와 같은 상태에서 문자표지판을 설치하게 되는 경우 문자표지판 설치작업이 지극히 곤란하게 되는 결점이 있다. 그리고, 이러한 문자표지판의 설치작업 곤란 등으로 설치상태가 불량하게 되면 문자표지판이 탈거될 염려가 있고 그리하면 가류된 타이어가 불량품으로 폐기되어지는 일이 있다. 또, 이와 같은 종래의 문자표지판설치부는 문자표지판 주연이 매끈하지 아니하여 성형되는 타이어에 식출이 생기는 등의 결점이 있다.By the way, in such a conventional mold, there is a drawback that the character sign installation is extremely difficult, especially when the letter sign mounting portion is installed in the upper mold, the mold is installed in the vulcanizer, and the character sign is installed in this state. In addition, when the installation state is poor due to such difficult installation work of the letter board, there is a possibility that the letter board is removed, and the vulcanized tire may be disposed of as a defective product. In addition, such a conventional character sign mounting portion has a drawback such that the extraction of the tires to be molded because the peripheral edge of the letter sign is not smooth.

이에 본 발명은 문자표지판 설치부에 자석을 설치하고 문자표지판을 철판으로 형성시킴으로서 문자표지판의 설치 및 교체 작업을 편리하게 한 것인 바, 이와 같은 본 발명을 첨부된 도면에 의하여 설명하면 다음과 같다. Accordingly, the present invention is to install a magnet on the letter plate mounting portion and to form a letter plate made of iron plate to facilitate the installation and replacement of the letter plate, as described in the accompanying drawings, the present invention as follows. .

내면에 타이어 외형에 대응하는 조각부가 형성되고 조각부가 타이어의 생산시기 등을 표시하기 위한 문자표지판설치부를 포함하는 것에 있어서, 본 발명은, 문자표지판설치부가 철판으로 된 문자표지판(1)과 문자표지판(1)을 설치하는 설치홈(2)으로 구성되고, 설치홈(2)은 문자표지판(1)의 둘레에 대응하는 둘레를 가지며 문자표지판(1)의 두께에 대응하는 깊이를 가지도록 형성된 주홈부(21)와 주홈부(21)의 주연에 형성된 경사홈(22)으로 구성되고, 주홈부(21)는 주홈부(21)상에 형성된 자석식입홈(23)과 자석식입홈(23)에 설치된 자석(24)으로 구성된다.In the present invention, the engraving portion corresponding to the tire shape is formed, and the engraving portion includes a letter board mounting portion for displaying the tire production time and the like. (1) consists of an installation groove (2), the installation groove (2) has a circumference corresponding to the circumference of the character sign plate 1 and formed to have a depth corresponding to the thickness of the character sign plate (1) It is composed of the inclined groove 22 formed on the periphery of the groove portion 21 and the main groove portion 21, the main groove portion 21 is provided in the magnet type groove 23 and the magnet type groove 23 formed on the main groove 21 It consists of a magnet 24.

이와 같이 구성된 본 발명은, 알루미늄으로 된 금형의 주홈부(21)에 형성된 자석식입홈(23)에 자석이 식입되어 있으므로 문자표지판(1)을 주홈부(21)에 끼우면 자석(24)이 철판으로 된 문자표지판(1)을 흡착하여 이탈을 방지하면서 설치시킨다.According to the present invention configured as described above, the magnet is inserted into the magnet type groove 23 formed in the main groove 21 of the mold made of aluminum, so that when the letter sign plate 1 is inserted into the main groove 21, the magnet 24 becomes an iron plate. The letter sign board 1 is adsorbed and installed while preventing separation.

이와 같이 설치된 문자표지판(1)을 제거함에 있어서는, 문자표지판(1)의 주연을 누르면, 주홈부(21)의 주연에 경사홈(22)이 형성되어 있으므로, 문자표지판(1)이 쳐들리게되며 따라서 문자표지판(1)을 용이하게 제거하여 교체할 수 있게 된다. In removing the character sign board 1 installed in this way, when the peripheral edge of the character sign board 1 is pressed, since the inclined grooves 22 are formed at the periphery of the main groove 21, the character sign board 1 is lifted. Therefore, the letter sign (1) can be easily removed and replaced.

이와 같은 본 발명은, 문자표지판 설치부에 자석을 설치하고 문자표지판을 철판으로 형성시킴으로서 문자표지판의 설치 및 교체 작업을 지극히 편리하게 하며, 교체시 약한 금형의 손상 염려를 감소시키고 타이어에 발생 가능한 문자표지판 주변의 식출을 제거할 수 있는 효과가 있다.The present invention is very convenient to install and replace the character signboard by installing a magnet on the letter board mounting portion and forming the letter sign plate with iron plate, reducing the risk of damage to the weak mold when replacing the letters that can occur on the tire It is effective to eliminate the extraction around the sign.
