본 고안은 타이어 가류용 금형의 상부에 실리콘 박스를 구비하여, 타이어 가류시, 타이어 트레드면에 실리콘을 도포함으로서, 타이어 인출시, 조각 절상으로 인해 제품에 손상이 가는 것을 방지한 타이어 가류용 금형에 관한 것이다.The present invention includes a silicon box on the upper part of the tire vulcanization mold, and includes silicone on the tire tread surface when the tire is vulcanized, so that the tire vulcanization mold which prevents damage to the product due to cuts during tire extraction. It is about.
타이어 가류용 금형에는 상형, 하형으로 된 두조각 금형(two piece mold)과 여러 조각으로 이루어진 세그먼트 금형(segment mold)이 있다. 전자는 트레드 중심부에 금형 분리선을 가지고 있고 또 상·하형으로 나누어져 가류공정을 마치는 금형으로서, 금형을 개방할 때, 금형 내부로 돌출된 금속재질의 그루브 조각과 고무 재질의 트레드 사이에 간섭현상이 발생하여 트레드 부분에 조각절상(Tearing)이 생기고, 특히 타이어 가류시, 그린케이스의 변형이 많아 품질면에서 가류도가 균일하지 않은 폐단이 있는데 반해, 후자는 상기 두조각 금형이 가지고 있는 단점을 보완하기 위하여 금형조각을 다수개로 나누었으니, 공정상 관리하기가 어렵고, 금형제작에 높은 생산비가 소모되어 제품가 상승을 유발하며, 여기에 덧붙여 금형을 교체하는데 많은 시간이 소모되는 결점이 있다.Tire vulcanization molds include a two piece mold of upper and lower molds and a segment mold of several pieces. The former has a mold separation line at the center of the tread and is divided into upper and lower molds to finish the vulcanization process.When the mold is opened, there is an interference phenomenon between the groove of the metal material and the tread of the rubber material when the mold is opened. There is a tearing in the tread part, and especially in the case of tire vulcanization, there is a closed end where the degree of vulcanization is not uniform in quality due to the deformation of the green case, whereas the latter compensates for the disadvantages of the two-piece mold. In order to divide the mold into a plurality of pieces, it is difficult to manage in the process, the high production cost is consumed in the mold production, causing the rise of the product, in addition to the defect that takes a lot of time to replace the mold.
이에, 본 고안에서는 상기의 문제점을 개선하기 위해, 두조각 금형에 자동유압분사장치를 가진 실리콘 박스를 구비하고, 또 상기 금형의 내면쪽에는 트레드 폭방향으로 상기 자동유압 분사장치에 연결되는 공급로를 형성하여 실리콘을 분사하므로써 트레드 부위에 실리콘 오일이 골고루 도포되도록 하여 절상으로 인한 제품 타이어의 손상을 방지함을 목적으로 한다.Thus, in the present invention, in order to improve the above problems, a two-piece mold is provided with a silicon box having an automatic hydraulic injection device, and the inner surface of the mold is connected to the automatic hydraulic injection device in the tread width direction By spraying the silicon by forming a silicon oil to be evenly applied to the tread area to prevent damage to the product tires due to the raise.
이하, 본 고안의 타이어 가류용 금형에 대해 첨부도면에 의거하여 상세히 설명한다.Hereinafter, the tire vulcanization mold of the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 상형(1) 및 하형(2)으로 이루어진 두조각 금형에 있어서, 상기 상형(1) 및 하형(2)상에 자동유압 분사장치를 가진 실리콘 박스(6)를 장착하고, 상기 상형 및 하형에 트레드부 폭방향으로 0~0.2㎜ 직경의 실리콘 오일 공급로(8)를 다수개 형성하여 상기 실리콘 박스(6)와 연결한 것을 특징으로 한다.The present invention is a two-piece mold consisting of the upper mold (1) and the lower mold (2), the silicon box (6) having an automatic hydraulic injection device on the upper mold (1) and the lower mold (2), the upper mold and The lower die is formed with a plurality of silicon oil supply passages 8 having a diameter of 0 to 0.2 mm in the width direction of the tread part, and is connected to the silicon box 6.
이상과 같이 구성되는 본 고안의 두조각 금형에 그린케이스(5)를 삽입한 후, 상기 실리콘 박스(6)에서 자동조절되는 실리콘 오일을 타이어 트레드면에 형성된 공급로(8)를 통해 분사하여, 가류완료 후 상형을 열고 타이어를 인출하면, 상기 오일의 작용에 의해서 절상이 일어나지 않는다. 트레드 표면에 실리콘을 도포하면, 타이어 인출시, 타이어 트레드 조각과 금형 그루브 조각과의 압착으로 인한 마찰력을 최소한으로 줄일 수 있게 된다.After inserting the green case 5 into the two-piece mold of the present invention configured as described above, by spraying the silicone oil automatically adjusted in the silicon box 6 through the supply path 8 formed on the tire tread surface, After the vulcanization is completed, when the upper mold is opened and the tire is taken out, the cut does not occur due to the action of the oil. The application of silicone to the tread surface minimizes the frictional forces due to the compression of the tire tread piece and the mold groove piece when the tire is taken out.
따라서, 본 고안은 타이어 가류완료 후 금형으로부터 타이어를 인출시, 트레드의 절상을 방지함으로서 타이어의 외관품질을 향상하고, 불량률을 감소시키며, 종래에는 작업자가 수작업으로 직접 도포하였던 것을 본 고안에서는 자동으로 분사되도록 하였으므로 생산능률면에서도 매우 향상된 것이다.Therefore, the present invention improves the appearance quality of the tire and reduces the defective rate by preventing the tread from cutting when the tire is taken out of the mold after the completion of the tire vulcanization, and in the present invention, the manual application by a worker by hand is automatically performed. Since it is sprayed, it is very improved in terms of production efficiency.
여기서, 미설명부호 4는 비드링 조각을, 7은 그루브를 나타낸다.Here, reference numeral 4 denotes a bead ring piece, 7 denotes a groove.
