Description
본 고안은 타이어 가류기의 열판 구조에 관한 것으로, 가류기의 열판을 이중으로 장착하고 이 열판에 공급되는 열원을 다르게 설정하여 몰드의 각 부위에 전달되는 열량이 조절되어 그린타이어 각 부위의 가류상태가 균일하게 되고 가류시간이 단축됨으로써 품질 및 생산성이 향상되도록 된 가류기의 열판 구조에 관한 것이다.The present invention relates to a hot plate structure of a tire vulcanizer. The heat plate of the vulcanizer is double mounted, and the heat source supplied to the hot plate is set differently so that the amount of heat transferred to each part of the mold is controlled so that the vulcanization state of each part of the green tire is controlled. It is related with the hot plate structure of a vulcanizer in which the uniformity and the vulcanization time are shortened and the quality and productivity are improved.
일반적으로 가류공정은 성형공정에서 완성된 그린타이어를 가류기의 타이어 몰드와 브래더 사이에 삽입하고 내측 및 외측에서 열과 압력증기를 가해서 일정시간 동안 경과시켜서 배합과정에서 투입된 가류제를 반응시켜 타이어내의 유황과 고무 분자가 완전히 결합하여 안정된 고유물성을 얻으며 또한 몰드에 의해 독특한 트래드 디자인과 사이드모양, 각인문자 및 상표등이 찍히게되는 공정으로, 통상 가류기는 상, 하측의 열판과 이 열판에 접하여 열이 전달되는 몰드 및 그린타이어 내측에서 열을 전달하고 타이어 내부형상을 형성하는 브래더(bradder)가 구비되는데, 상기 열판에 고온의 스팀이 공급되어 이 열판에 접한 몰드에 열이 전달되고 다시 몰드 내부의 그린타이어에 열량이 전달되어 그린타이어의 가류가 이루어진다. 또한 그린타이어 내측에 접한 브래더의 내측으로부터도 열과 압력이 공급되고 브래더가 팽창하게 되어 몰드와 브래더 사이의 그린타이어를 압축하면서 열을 전달하게된다.In general, the vulcanization process inserts the green tire completed in the molding process between the tire mold and the bladder of the vulcanizer, and heats and pressures steam inside and outside for a predetermined time to react the vulcanizing agent introduced in the compounding process. Sulfur and rubber molecules are completely combined to obtain stable intrinsic properties, and unique tread designs, side shapes, imprinted letters, and trademarks are imprinted by the mold. In general, the vulcanizer is in contact with the upper and lower hot plates and the hot plates. There is provided a mold to transfer the heat inside the green tire and the tire (bradder) to form the internal shape of the tire, a hot steam is supplied to the hot plate is transferred to the mold in contact with the hot plate and the inside of the mold The heat is transferred to the green tires, thereby vulcanizing the green tires. In addition, heat and pressure are also supplied from the inner side of the bladder in contact with the inside of the green tire, and the bladder is expanded to transfer heat while compressing the green tire between the mold and the bladder.
그러나, 상기와 같은 종래의 가류기의 열판 구조는 동일한 열원이 열판에 공급되어 가류가 진행되므로 몰드내에 전달되는 열량이 각부분별로 차이가 나게되는데, 즉 몰드가 두꺼운 트래드부분은 열이 늦게 전달되고 몰드가 얇은 사이드월 부분은 열이 빨리 전달되므로 사이드월과 같은 부위는 트래드부위보다 상대적으로 가류가 빨리 진행되게된다.However, in the hot plate structure of the conventional vulcanizer as described above, since the same heat source is supplied to the hot plate and vulcanization proceeds, the amount of heat transferred into the mold is different for each part. Thin-walled sidewalls transfer heat faster, so parts like sidewalls tend to vulcanize faster than treads.
따라서 가류가 가장 늦은 부위의 가류가 진행중인 때에 이미 가류가 된 부위는 과가류 현상이 일어나게되어 타이어의 품질이 저하되며 실제 타이어가 시험실에서 요구된 물성을 만족하는 성능을 얻기 어려운 문제점이 있었다.Therefore, when vulcanization is in progress at the latest vulcanization part, the vulcanized part has a problem of excessive vulcanization, and the quality of the tire is deteriorated.
이에 본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 상하측 열판의 측면부에 몰드 측면부와 접하도록 열판을 추가로 장착하고 이 열판에 가해지는 열량을 다르게 설정하여 균일한 가류상태를 얻음으로써 타이어의 품질이 향상되고 가류시간의 단축으로 생산성이 향상되도록 된 가류기의 열판구조를 제공하는데 그 목적이 있다.The present invention is devised to solve the above problems, by additionally installing a hot plate to contact the mold side portion in the upper and lower side of the hot plate and by setting different amounts of heat applied to the hot plate to obtain a uniform vulcanization state An object of the present invention is to provide a hot plate structure of a vulcanizer in which tire quality is improved and productivity is improved by shortening vulcanization time.

도 2는 도 1의 대응도로서 종래의 가류기의 열판구조이다.FIG. 2 is a hot plate structure of a conventional vulcanizer as a corresponding diagram of FIG. 1.

상기와 같은 목적을 달성하기위한 본 고안은 가류기의 상·하부에 각각 제 1열판이 설치되고, 이 열판의 측면부에 몰드의 측면과 접지하도록 제 2열판이 설치되는데, 상기 제 1열판의 위아래에 대칭으로 몰드가 형성되고, 이 몰드에 형성된 공동의 내부에 가류기의 중앙지지대에 취부된 브래더가 설치되는 한편, 이 브래더와 몰드 사이에 그린타이어가 삽입되는 구조로 되어있다.The present invention for achieving the above object is the first hot plate is installed on the upper and lower portions of the vulcanizer, respectively, the second hot plate is installed to the ground side and the side of the mold, the top and bottom of the first hot plate The mold is formed symmetrically, and a bladder attached to the central support of the vulcanizer is provided inside the cavity formed in the mold, while the green tire is inserted between the bladder and the mold.
이하 본 고안을 첨부된 도면에 의거하여 상세히 설명하고자 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 고안에 따른 가류기의 열판구조의 단면도인바, 가류기의 상하부에 고온의 스팀을 공급받는 제 1열판(1)이 상하측몰드(2, 2')와 접하도록 장착되고, 상기 제 1열판(1)의 측면부에 상,하측몰드(2, 2')의 측면과 접하도록 제 2열판(1')이 장착되며, 상측몰드(2)와 하측몰드(2')는 서로 대칭형상으로 형성되어 이 상하측몰드가 서로 접하는 부분에 공동이 형성되되, 이 공동 내에 중앙지지대에 취부된 브래더(4)가 내설되고, 이 브래더(4)와 몰드(2, 2') 사이에 그린타이어(3)가 삽입된 구조로 되어 있다.1 is a cross-sectional view of a hot plate structure of a vulcanizer according to the present invention, wherein a first hot plate 1 receiving hot steam is provided in contact with upper and lower molds 2 and 2 'at upper and lower portions of the vulcanizer. The second heat plate 1 'is mounted on the side surface of the first heat plate 1 so as to be in contact with the side surfaces of the upper and lower molds 2 and 2', and the upper mold 2 and the lower mold 2 'are symmetric with each other. A cavity is formed at a portion where the upper and lower molds come into contact with each other, and a bladder 4 mounted on a central support is installed in the cavity, and between the bladder 4 and the molds 2 and 2 '. The green tire 3 is inserted in the structure.
따라서 고온의 스팀이 열판(1, 1')에 공급되면 이 열판(1, 1')과 접하고 있는 몰드(2, 2')의 상하부면과 측면으로 각각 열량이 전달되고 다시 몰드(2, 2')와 브래더(4)사이의 그린타이어(3)에 열량이 전달됨으로써 가류가 되는데, 가류가 늦게 진행되는 트래드부(3a)와 인접한 몰드(2, 2')의 측면부를 가열하는 제 2열판(1')의 온도를 가류가 상대적으로 빨리 진행되는 사이드월부(3b)와 인접한 상하부면을 가열하는 제 1열판(1)의 온도보다 상대적으로 높게 설정함으로해서 트래드부(3a)의 가류속도를 빠르게 할 수 있게되므로 그린타이어(3) 전체적으로 가류상태를 균일하게 할 수 있게된다.Therefore, when hot steam is supplied to the hot plates 1 and 1 ', the heat is transferred to the upper and lower surfaces and the side surfaces of the molds 2 and 2' which are in contact with the hot plates 1 and 1 ', respectively. The amount of heat is transferred to the green tire 3 between ') and the bladder 4 so that it is vulcanized. The second heating part of the side of the mold 2 and 2' adjacent to the tread portion 3a where the vulcanization progresses is late. The vulcanization rate of the tread portion 3a is set by setting the temperature of the hot plate 1 'to be relatively higher than the temperature of the first hot plate 1 heating the upper and lower surfaces adjacent to the sidewall portion 3b where vulcanization proceeds relatively quickly. Since it is possible to speed up the green tire (3) as a whole it becomes possible to make the vulcanization state uniform.
이상 설명한 바와 같이 본 고안에 따르면, 가류가 상대적으로 늦게 진행되는 부위의 가류속도가 더 빠르게 진행되고 가류가 상대적으로 빠르게 진행되는 부위의 가류속도가 더 늦게 진행되므로 그린타이어 전부분에서 가류상태가 균일하게 되며, 가류시간이 단축되므로 타이어의 품질이 향상되고 생산성이 향상되는 효과가 있다.As described above, according to the present invention, since the vulcanization speed of the portion where the vulcanization proceeds relatively faster progresses and the vulcanization speed of the portion where the vulcanization proceeds relatively faster proceeds later, the vulcanization state is uniform throughout the green tire. And, since the vulcanization time is shortened, there is an effect that the quality of the tire is improved and the productivity is improved.
