Abstract

PURPOSE: A tire curing mold is provided to prevent the projection and stepped gap of rubber by symmetrically forming a concave unit and a protrusion unit at divided surfaces and precisely coupling the divided molds. CONSTITUTION: A tire curing mold is composed of divided units(1,2) divided up and down or radially. A concave unit(3) and a protrusion unit(4) are symmetrically formed at divided surfaces(11,21), respectively. The concave unit and protrusion unit have a depth and height of 2-5mm, respectively.

Description

타이어 가류용 금형{Tire vulcanizing mold}Tire vulcanizing mold

본 발명은 타이어 가류용 금형에 관한 것으로 특히, 분할된 금형의 결합 상태를 개선할 수 있게 하여서 된 것이다.The present invention relates to a tire vulcanization mold, and in particular, to improve the bonding state of the divided mold.

타이어 가류용 금형에는, 금형을, 상하로 분할한 이른 바 투피스 몰드(Two-piece mold)와 금형을 방사상으로 다수 분할한 섹셔널 몰드(Sectional mold) 가 있는 바, 이와 같이 상하로, 또는 방사상의 방향으로 분할 된 가류금형이 그 결합상태가 불완전하게 되면 분할면을 통하여 고무가 식출되거나 단차가 발생하여 타이어의 균일성을 해하게 될 염려가 있으며, 또 소음 발생의 염려가 있게 된다. 뿐만 아니라, 특히 그루브에 식출이 생기면 식출고무가 그루브의 통로를 막아 배수성능을 저하시키는 중대한 결점이 발생하게 된다.The tire vulcanization mold includes a so-called two-piece mold in which the mold is divided up and down, and a section mold in which a plurality of molds are radially divided. If the vulcanization mold divided in the direction is incompletely coupled, the rubber may be extracted through the divided surface, or a step may occur, thereby deteriorating the uniformity of the tire, and there is a fear of noise generation. In addition, especially when grooves are extracted in the groove, a significant drawback occurs that the extraction rubber blocks the passage of the groove to reduce drainage performance.

이에 본 발명은, 분할된 금형의 분할면에 서로 대칭이 되게 요함부와 돌출부를 형성시킴으로써, 요함부와 돌출부가 분할된 금형이 분할면에서 정확한 위치로 결합되도록 안내하도록 한 금형을 제공함으로써 분할면의 부적절한 결합으로 인한 식출이나 단차의 발생을 방지할 수 있게 한 것인 바, 이와 같은 본 발명을 첨부된 도면에 의하여 설명하면 다음과 같다.Accordingly, the present invention provides a mold in which the recess and the protrusion are symmetrically formed on the divided surface of the divided mold, thereby providing a mold for guiding the divided mold and the protrusion divided into the correct position on the divided surface. It is to be able to prevent the occurrence of extraction or step due to improper combination of the present invention will be described with reference to the accompanying drawings as follows.

본 발명은, 상하 또는 방사상으로 다수 분할된 분할부(1, 2)로 구성된 가류 금형에 있어서, 분할된 금형의 분할면(11, 21)에 서로 대칭이 되게 요함부(3)와 돌출부(4)를 형성시키는 것을 특징으로 한다.According to the present invention, in the vulcanizing mold composed of the divided parts 1 and 2 divided into a plurality of vertically or radially, the recessed part 3 and the protrusion 4 are symmetrical to each other on the divided surfaces 11 and 21 of the divided mold. It is characterized by forming a).

요함부(3)와 돌출부(4)의 형상은 기다란 형상의 돌조와 이에 대응하는 기다란 요홈으로 형성시킬 수 있으며, 반구, 원추형 등 임의의 형상으로 형성시킬 수 있다.The concave portions 3 and the protrusions 4 may be formed of elongated protrusions and elongated grooves corresponding thereto, and may be formed into arbitrary shapes such as hemispheres and cones.

그리고 요함부(3)의 깊이나 돌출부(4)의 높이는 2∼5mm 정도인 것이 바람직하다.And it is preferable that the depth of the recessed part 3 and the height of the protrusion part 4 are about 2-5 mm.

이와 같이 구성된 본 발명은, 분할된 금형의 분할면(11, 21)에 정확한 위치로의 결합을 안내하는 요함부(3)와 돌출부(4)가 형성되어 있어 결합 위치의 어긋남이 발생할 염려가 없게 되며, 따라서, 타이어의 가류시 분할면의 불완전 결합으로 인한 식출이나 단차가 발생할 염려가 없어 타이어의 품위를 저하시킬 염려가 없게 되는 효과가 있다.According to the present invention configured as described above, recesses 3 and protrusions 4 are formed on the divided surfaces 11 and 21 of the divided molds to guide the coupling to the correct positions so that there is no fear of misalignment of the coupling positions. Therefore, there is no fear of extraction or step difference due to incomplete coupling of the divided surface when the tire is vulcanized.
