Abstract

A vulcanizing mold for tire is provided to change the shape and dimension or the installation position of a main groove by detaching a main groove molding protrusion. A vulcanizing mold for tire comprises an upper side wall molding part, a lower side wall molding part, a divided thread molding part(1), and a main groove molding protrusion part(2) inside the tread molding part. The main groove molding protrusion is removable from the tread molding part. A main groove molding protrusion of a tread molding part is attached or detached to/from each other through a magnet.

Description

타이어 가류용 금형{Vulcanizing mold for tire}Vulcanizing mold for tire

본 발명은 타이어 가류용 금형에 관한 것으로, 특히 트레드성형부의 개량에 관한 것이다. 더욱 상세히 말하면 트레드 성형부를 조립식으로 형성시켜서 된 가류 금형에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire vulcanization mold, and more particularly to an improvement in a tread molding portion. More specifically, the present invention relates to a vulcanization mold formed by prefabricating a tread molded part.

종래의 일반적인 타이어 가류금형은 일단 제작된 금형의 경우 트레드성형부의 내부 형상을 변경할 수 없는 결점이 있다. 그리하여 트레드성형부를 홀더와 이에 결합되는 다수의 분할부재로 형성시켜 다수의 분할부재를 교체 결합함으로서 다양한 형태의 트레드부를 형성시킬 수 있도록 하여서 된 타이어가 제공된 바 있다(일본국 특개평8-72061). 그러나, 이는 가류 금형이 지나치게 여러 부분으로 분할되어 있어 결합부위에서 누출로 인한 식출이 발생할 염려가 커사 실용적이지 못한 결점이 있다.Conventional tire vulcanization molds have the drawback that the internal shape of the tread molded part cannot be changed in the case of a mold once manufactured. Thus, there has been provided a tire in which a tread molding part is formed of a holder and a plurality of dividing members coupled thereto, thereby forming various types of tread portions by replacing and combining a plurality of dividing members (Japanese Patent Laid-Open No. 8-72061). However, this is not practical because the vulcanization mold is divided into too many parts and the extraction from the leak is likely to occur.

이에 본 발명은 상기와 같은 조립식 트레드성형부를 개량하여 식출 및 금형의 취약성을 개선하면서도 트레드의 형상을 변경시킬 수 있게 하는 금형을 제공하여야 한다는 과제를 해결하고자 한다.Therefore, the present invention is to solve the problem of improving the prefabricated tread molding as described above to provide a mold that can change the shape of the tread while improving the extraction and fragility of the mold.

위와 같은 과제의 해결을 위하여, 본 발명은 적어도 주행방향으로 형성되는 주그루브를 형성시키는 주그루브성형돌출부만은 이를 착탈식의 구조로 형성시켜서 되는 가류금형을 제공한다.In order to solve the above problems, the present invention provides a vulcanization mold in which only the main groove forming protrusion forming the main groove formed in the driving direction is formed in a removable structure.

위와 같은 본 발명은, 금형 자체를 분할시킴에서 오는 금형의 취약성이나 식출의 염려 없이, 필요에 따라 주그루브의 설치 위치나 주그루브의 형상 및 치수를 변경시킬 수 있게 하는 효과가 있다.The present invention as described above has the effect of being able to change the installation position of the main groove and the shape and dimensions of the main groove as necessary, without fear of fragility or extraction of the mold resulting from dividing the mold itself.

상측 사이드월성형부와 하측 사이드월 성형부 및 분할된 트레드성형부로 되고 트레드성형부(1)의 내부에 주그루브성형돌출부가 형성되는 것에 있어서, 본 발명은, 주그루브성형돌출부(2)가 트레드성형부(1)에 착탈 자재롭게 설치된 것을 특 징으로 한다.In the present invention, in which the upper groove wall forming part, the lower side wall forming part and the divided tread forming part are formed, and the main groove forming protrusion is formed inside the tread forming part 1, the main groove forming protrusion 2 is formed in the tread forming part. It is characterized by the fact that it is detachably attached to the part (1).

트레드성형부(1)에의 주그루브브성형돌출부(2)의 착탈구조는, 트레드성형부(1)와 주그루브성형돌출부(2)를 자석에 의한 착탈구조로 구성시킬 수 있으며, 또한, 첨부된 도면에 도시된 바와 같이, 트레드성형부(1)에 결합돌조(11)를 형성시키고 주그루브성형돌출부(2)에 결합요홈(21)을 형성시켜서된 착탈구조로 구성시킬 수 있다.The detachable structure of the main groove forming protrusions 2 to the tread forming part 1 can constitute the detachable structure of the tread forming part 1 and the main groove forming protrusions 2 by a magnet. As shown in the figure, it is possible to form a detachable structure formed by forming the engaging protrusion 11 in the tread forming part 1 and the engaging groove 21 in the main groove forming protrusion 2.

트레드성형부(1)와 주그루브성형돌출부(2)를 자석에 의한 착탈구조로 구성시키게 되면, 착탈이 극히 용이할 뿐 아니라, 트레드성형부(1)에 착설된 상태에서 주그루브성형돌출부(2)를 좌우로 밀어 그 설치 위치를 조정할 수도 있게 된다. 그리고, 착탈구조를 트레드성형부(1)에 결합돌조(11)를 형성시키고 주그루브성형돌출부(2)에 결합요홈(21)을 형성시켜서된 착탈구조로 구성시키게 되면 측벽의 경사각을 다양하게 형성시켜서 되는 그루브성형돌출부(2)를 용이하게 선택 설치할 수 있게 된다. When the tread forming part 1 and the main groove forming protrusion 2 are formed in a detachable structure by magnets, the main groove forming protrusions 2 are not only easily detachable but also attached to the tread forming part 1. You can also adjust) the installation position by sliding left and right. When the detachable structure is formed in the detachable structure by forming the engaging protrusion 11 in the tread molding part 1 and forming the engaging recess 21 in the main groove forming protrusion part 2, the inclination angle of the side wall is variously formed. The groove forming protrusions 2 to be made can be easily selected and installed.
