Description
본 발명은 그린 타이어를 가류시키는 타이어 가류금형에 관한 것으로, 더욱 상세하게는 타이어를 가류시키는 열원을 개량하여 고무두께가 두꺼운 트래드부위와 상대적으로 고무두께가 얇은 사이드월부위의 가류정도를 균일하게 유지할 수 있게 하여 미가류 또는 과가류로 인한 불량의 발생을 방지할 수 있게 하는 타이어 가류금형에 관한 것이다.The present invention relates to a tire vulcanization mold for vulcanizing a green tire, and more particularly, to improve the heat source for vulcanizing a tire to maintain the degree of vulcanization of a tread portion having a thick rubber thickness and a sidewall portion having a relatively thin rubber thickness. It relates to a tire vulcanization mold that makes it possible to prevent the occurrence of defects due to uncured or over-cured.
일반적으로 그린 타이어를 가류에 필요한 시간 설정은 고무의 두께가 두꺼워 가류가 가장 늦게 이루어지는 트래드부를 기준으로 설정된다.In general, the time setting required for vulcanizing the green tire is set based on the tread portion where vulcanization occurs at the latest due to the thick rubber.
특히, 사이드월부는 트래드 및 비드부에 비해 고무의 두께가 상대적으로 얇은 반면에 가류시간은 여타 부위와 동일하게 설정되어 과가류 정도가 심하여 타이어의 품질을 저하시키는 주요원인으로 지적되고 있다.In particular, the sidewall portion has a relatively thin thickness of the rubber compared to the tread and the bead portion, while the vulcanization time is set to the same as other parts, the degree of excessive vulcanization is pointed out as a major cause of deterioration of the tire quality.
이러한 문제점을 해결하기 위하여 종래에는 사이드금형의 내부에 과가류방지용 냉각라인과 스팀라인을 별도로 설치시켜 사이드월부가 과가류되는 것을 방지할 수 있게 하는 것이 제공된 바 있다.(특허공개 99-025118호)In order to solve this problem, it has been conventionally provided that the sidewall portion can be prevented from being over-cured by separately installing a cooling line and a steam line for preventing over-curing inside the side mold. number)
그러나 상기한 바와 같은 선행기술은 스팀라인과 냉각라인을 사이드금형의 내부에 설치시키는 작업이 용이하지 않고, 전열판에서 전도되는 열에 의해 냉각라인의 온도가 상승됨으로써 정확하게 온도를 조절할 수 없어 그 효과가 미비한 문제점이 있다.However, the prior art as described above is not easy to install the steam line and the cooling line in the inside of the side mold, the temperature of the cooling line is increased by the heat conducted from the heat transfer plate, the temperature can not be accurately controlled, the effect is insignificant. There is a problem.
또 다른 종래의 기술로서, 두께가 얇은 사이드금형을 열전도율이 낮은 철제재질로 형성시키고, 두께가 두꺼운 트래드금형을 열전도율이 높은 비철금속을 제작하여 과가류 및 미가류를 방지할 수 있게 하는 것이 제공된 바 있다.(특허공개96-762)As another conventional technique, it is provided that the thin side mold is formed of a low thermal conductivity iron material, and the thick tread mold is made of a non-ferrous metal having high thermal conductivity to prevent over- and under-curing. (Patent Publication 96-762)
그러나 상기한 바와 같은 또 다른 선행기술은 철제와 비철금속간의 열팽창계수가 서로 달라 전열판에서 고온이 전열될 때 가류금형에 변형이 발생되어 타이어의 형상에 영향을 미치게 되며, 장시간에 걸쳐 전열이 이루어 졌을 때 열전도율이 낮은 철재금형이라 할지라도 고온으로 상승하여 기존 가류금형과 같이 사이드월부가 과가류되어 타이어의 품질을 저하시키는 문제점이 있다.However, another prior art as described above is different from the coefficient of thermal expansion between iron and non-ferrous metal when the high temperature is transferred from the heat transfer plate deformation occurs in the vulcanizing mold affects the shape of the tire, when the heat transfer over a long time Even if the steel mold having a low thermal conductivity rises to a high temperature, there is a problem in that the sidewall portion is excessively vulcanized like the existing vulcanization mold, thereby degrading the quality of the tire.
본 발명은 상기와 같은 종래의 문제점을 해결하기 위한 것으로서, 본 발명은 타이어를 가류시키는 열원을 온도조절이 용이한 것으로 개량하여 고무두께가 두꺼운 트래드부위와 상대적으로 고무두께가 얇은 사이드월부위의 가류정도를 균일하게 유지할 수 있게 하여 미가류 또는 과가류로 인한 불량의 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 improves the heat source for vulcanizing the tire to easy temperature control, so that the vulcanization of the tread portion with a thick rubber thickness and the sidewall portion with a relatively thin rubber thickness It is an object of the present invention to provide a tire vulcanization mold that can maintain the degree uniformly and prevent the occurrence of defects due to uncured or excessive vulcanization.
본 발명은 상기와 같은 목적을 달성하기 위하여 다음과 같이 구성된다. 즉, 본 발명은 상하 사이드금형과, 다수개로 분할형성되는 트래드금형으로 구성되는 것에 있어서, 상기 상하 사이드금형의 외측에 전기를 에너지로 발열하는 전기히터를 설치시키고, 상기 다수개로 분할형성되는 트래드금형의 외측에도 전기히터를 설치시키며, 사이드금형의 외측에 설치되는 전기히터의 발열온도가 트래드금형의 외측에 설치되는 전기히터의 발열온도 보다 낮게 설정시켜 구성되는 것에 특징을 둔 것이다.The present invention is configured as follows to achieve the above object. That is, the present invention comprises an upper and lower side mold and a tread mold divided into a plurality, wherein an electric heater for generating electricity with energy is installed outside the upper and lower side molds, and the tread mold is divided into a plurality of molds. The electric heater is also installed on the outside of the side mold, and the heat generation temperature of the electric heater installed on the outside of the side mold is set to be lower than the heat generation temperature of the electric heater installed on the outside of the tread mold.
