본 고안은 타이어 가류용 금형에 관한 것으로, 타이어 가류시에는 일반적으로 비드 부위의 가류가 늦어지게 되므로 비드부위가 충분히 가류될 때 까지 타이어를 가류하지 않으면 아니되고, 따라서 결과적으로 타 부위는 지나치게 가류되어 타이어의 품질을 저하시키는 원인이 되어 왔으며, 타이어의 가류시간을 길게하여 생산성이 저하되는 결점이 있었던 바, 본 고안은 가류가 가장 늦은 부위인 비드 부위에 열매체분사관과 스프링 엘리먼트 링(Spring element ring)을 설치하므로서 비드 부위만을 고르게 예열한 후 타이어를 가열할 수 있게 하여 비드부위가 타부위와 등가류(Equivalent cure)되도록 하고, 그리하여 타이어의 품질을 향상시키고 생산성을 향상시킬 수 있도록 한 것임.The present invention relates to a tire vulcanization mold, and in the case of tire vulcanization, since the vulcanization of the bead part is generally delayed, the tire must be vulcanized until the bead part is sufficiently vulcanized. It has been a cause of deterioration of the tire quality, there was a drawback that the productivity is lowered by lengthening the vulcanization time of the tire, the present invention is a thermal element injector and the spring element ring (Spring element ring) in the bead region of the last By preheating only the bead area evenly, the tire can be heated so that the bead part is equivalent to the other part. Therefore, the tire quality and productivity are improved.

Description

자동차 타이어 가류 금형Car tire vulcanization mold

본 고안은 타이어 가류용 금형에 관한 것으로, 특히 비드부의 예열장치를 가진 타이어 가류용 금형을 제공하기 위한 것이다.The present invention relates to a tire vulcanization mold, and more particularly, to provide a tire vulcanization mold having a bead preheating device.

타이어 가류용 금형은, 이에 설치되는 타이어의 비드부 주위에 브라더 크램프링이 설치되어 있으므로, 타이어의 비드부에의 열공급이 원활치 못하고 그리하여 일반적으로 비드 부위의 가류가 늦어지게 되므로 비드부위까지 충분히 가류될 때까지 타이어를 가류하지 않으면 아니되고, 따라서 결과적으로 열공급이 원활한 타부위가 지나치게 가류되어 타이어의 품질을 저하시키는 원인이 되어 왔으며, 타이어의 가류시간을 길게하여 생산성이 저하되는 결점이 있었다.Since the tire clamping mold is provided with a Brother clamping ring around the bead portion of the tire to be installed thereon, the heat supply to the bead portion of the tire is not smooth, so that the vulcanization of the bead portion is generally slowed down. Until the tire has to be vulcanized, the other part of which the heat supply is smooth is consequently vulcanized, resulting in deterioration of the quality of the tire.

상술한 바와 같이 비드부의 가류에 많은 시간이 소요되는 것은 비드부에 열매체의 공급이 적어 가열이 더딘데에 그 원인이 있다. 그리하여 본 고안은, 열원의 공급이 적어 가류가 가장 늦은 부위인 비드 부위에 별도의 열매체분사관과 스프링 엘리먼트 링(Spring element ring)을 설치하므로서 비드 부위만을 고르게 예열한 후 타이어를 가열할 수 있게 하였다. 그리하여 결과적으로 타이어의 고른 가열이 가능케하여 비드를 포함한 타이어의 전체 부위가 등가류(Equivalent cure)되어 부분적인 과가류 현상이 발생되지 아니하게 하므로서 타이어의 품질을 향상시키고 가류시간을 단축하여 생산성을 향상시킬 수 있도록 한 것인 바, 이와 같은 본 고안을 첨부된 도면에 의하여 설명하면 다음과 같다.As described above, a large amount of time is required for vulcanization of the bead portion, which is caused by a low supply of heat medium in the bead portion, resulting in slow heating. Thus, the present invention provides a heat preheating of the bead area evenly by installing a separate thermal spray tube and a spring element ring in the bead part, which has the lowest vulcanization due to the low supply of heat source. . As a result, the tire can be heated evenly so that the entire part of the tire including the beads is equivalent to cure so that no partial over-curing phenomenon occurs, thereby improving the quality of the tire and shortening the vulcanization time, thus improving productivity. It is intended to be improved, this invention will be described by the accompanying drawings as follows.

An extended flexible pipe 61 is provided, a ring-shaped flexible injection pipe 72 is installed at an end of the flexible pipe 61, and a plurality of injection holes 63 are provided at the upper and lower portions of the flexible injection pipe 62. ), And a dense coil ring 5 is provided on the upper and lower sides of the injection hole 63. The flexible tube 61 or the flexible spray tube 62 installed on the upper portion of the preheating tube 6 provides flexibility in charging or withdrawing the inside of the brother 1 to prevent breakage of the associated structure. The coil ring 5 functions as an equidistant holding zone for allowing the flexible spray pipe 62 to have an equidistant distance from the upper and lower bead portions of the tire 2, and the heat medium sprayed from the flexible spray pipe 62 is the brother ( Without heating the specific portion of the inner wall of 1), the heating medium is diffused by the coil ring 5, and the heating medium first heats the coil ring 5, and the heated coil ring 5 is the brother 1 The inner wall of the indirect heating is configured to preheat the bead portion of the tire evenly without damaging the inner wall of the brother on the bead portion side.

이와 같이 구성된 본 고안은 열 및 압력매체를 유입시키는 유입관(7)으로 열매체를 유입시키기 이전에, 예열관(6)을 통하여 열매체를 유입시키면, 열매체가 플렉시블분사관(62)의 분사공(63)들을 통하여 상하로 분사되고 코일 링(5)에 의하여 확산되면서 코일 링(5)을 가열하고, 또 확산되는 열매체와 가열된 코일 링(5)이 비드부측의 브라더 내벽을 가열하게 된다. 이와같이 하여 비드부가 충분히 예열되면, 유입관(7)을 통하여 브라더(1) 내부에 열매체를 유입시켜 타이어(2)를 가열하므로서 가류작업을 수행하게 된다.According to the present invention configured as described above, if the heat medium is introduced through the preheating tube 6 before the heat medium is introduced into the inlet pipe 7 through which heat and pressure medium are introduced, the heat medium is sprayed through the flexible injection pipe 62 ( The coil ring 5 is heated while being sprayed up and down through the 63 and diffused by the coil ring 5, and the heat medium and the heated coil ring 5, which are diffused, heat the inner wall of the brother on the bead part side. When the bead part is sufficiently preheated in this manner, the heating medium is introduced into the brother 1 through the inflow pipe 7 to heat the tire 2 to perform the vulcanization operation.

이와같은 본 고안은 비드부를 예열할 수 있게 하여 타이어의 일부가 과가류되는 일이 없게 하여 타이어의 품질을 향상시킬 수 있게 하며, 비드부를 예열함에 있어서도 예열을 위한 열매체가 분산되게 하고 또 코일 링(5)에 의하여 간접 가열되게 하여 브라더가 손상되는 일이 없게되는 효과가 있다.The present invention enables preheating of the bead part so that part of the tire is not over-cured so as to improve the quality of the tire. Also, in preheating the bead part, the heat medium for preheating is dispersed and the coil ring Indirect heating by (5) has the effect of avoiding damage to the brother.
