Description
본 고안은 타이어의 규칙과 용도 등을 표시하기 위해 타이어의 측면에 문자를 성형시키는 그린타이어 가류용 몰드의 문자판 구조에 관한 것으로, 가류용 몰드에 부착시 몰드의 표면과 일치되도록 함몰되어 가류됨으로써 타이어 표면의 단차를 제거하도록 된 그린 타이어 가류용 몰드의 문자판 취부구조에 관한 것이다.The present invention relates to a dial structure of a green tire vulcanizing mold for forming a letter on the side of the tire to indicate the rules and uses of the tire, the tire by being recessed and vulcanized so as to match the surface of the mold when attached to the vulcanizing mold A dial mounting structure of a green tire vulcanization mold adapted to remove the step difference of the surface.
일반적으로 자동차는 노면의 굴곡이나 장애물 등에 의한 지면으로부터의 충격을 방지하기 위하여 서스팬션 구조와 함께 타이어를 장착하여, 여러 방향으로부터의 하중이나 토크를 타이어 자체의 변형으로 그 외력에 대해 저항하도록 되어 진다.In general, a vehicle is equipped with a tire with a suspension structure to prevent the impact from the ground due to road curvature or obstacles, so that the load or torque from various directions to the external force by deformation of the tire itself.
한편, 상기 타이어는 성형공정에서 만들어진 그린타이어를 가류공정으로 보내 몰드로 넣게 되고, 하부몰드에서 주입되는 고온 고압 증기에 의한 팽창작용과 고온의 몰드의 작용으로 팽창시키며, 이 과정에서 팽창된 그린타이어가 타이어몰드의 내면에 눌리면서 트레드패턴, 사이드의 모양, 각인문자, 상표 등이 타이어 상에 찍히게 된다.On the other hand, the tire is sent to the vulcanization process of the green tires made in the molding process, and is inflated by the action of the high temperature and high pressure steam injected from the lower mold and the action of the high temperature mold, in this process the expanded green tire Is pressed on the inner surface of the tire mold, the tread pattern, the shape of the side, the carved letters, trademark, etc. are printed on the tire.
여기서, 상기 타이어상의 각인문자는 원형의 얇은판에 문자를 에칭하거나 문자조각기를 이용하여 가공한 문자판을 몰드의 사이드월부에 본드 등의 부착수단을 매개로 부착되는바, 종래 구조를 도시한 제3도에서와 같이 원하는 여러 가지 에칭문자(2a)가 새겨진 문자판(2)이 몰드의 사이드월(1) 상의 접착부(4)에 본드와 같은 부착수단으로 고정되어진다.Here, the imprinted characters on the tire is attached to the side wall of the mold by means of etching the characters in a circular thin plate or by using a letter engraving machine, through the attachment means such as bond, the third structure showing a conventional structure As shown in the figure, the dial 2 engraved with the desired etching characters 2a is fixed to the bonding portion 4 on the sidewall 1 of the mold by means of attachment such as bonds.
그러나, 상기와 같이 문자판(2)이 접착부(4)를 매개로 몰드에 부착되어지게 되면, 타이어의 가류과정시 고온 고압에 의해 상기 접착부(4)가 어느 정도 용융되면서 부착력이 저하되고, 이로 인해 문자판(2)이 사이드월(4) 상에서 이동되면서 타이어상에 각인문자의 위치가 편향되는 즉, 삐뚤어지는 현상이 발생되고, 또한 문자판(2)이 몰드의 사이드월(1)에 어느 정도 돌출된 형태로 부착되므로 완성된 타이어 상에서 각인문자 부분이 타이어 내로 함몰되어 각인문자 부분과 타이어 표면의 단차가 발생하는 문제점이 있었다.However, when the dial 2 is attached to the mold through the adhesive portion 4 as described above, the adhesive force is reduced while melting the adhesive portion 4 to some extent by the high temperature and high pressure during the curing process of the tire, thereby As the dial 2 is moved on the sidewall 4, the position of the imprinted characters on the tire is deflected, that is, a skewing phenomenon occurs, and the dial 2 is projected to the sidewall 1 of the mold to some extent. Since it is attached in the form, there is a problem that the carved letter portion on the finished tire is recessed into the tire to cause a step between the carved letter portion and the tire surface.
이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 몰드의 사이드월상에 문자판이 삽입되는 안착부를 구성하도록 하여 몰딩과정에서 발생하는 타이어상의 단차를 제거하고 문자판의 이동을 방지하도록 된 그린타이어 가류용 몰드의 문자판 취부구조를 제공함에 그 목적이 있다.The present invention is devised to solve the above problems, to form a seating portion that is inserted into the dial on the sidewall of the mold to eliminate the step on the tire generated during the molding process and to prevent the movement of the green tire The purpose is to provide a dial mounting structure for a vulcanizing mold.
제1도는 본 고안에 따라 타이어몰드 상에 부착되는 문자판의 분리단면도.1 is an exploded cross-sectional view of the dial attached to the tire mold according to the present invention.
제2도는 제1도에 따른 문자판의 세부확대도.2 is a detailed enlarged view of the dial according to FIG.
제3도는 종래구조로서 그린타이어 가류용 몰드 상에 부착된 문자판이 어느 정도 돌출된 상태를 나타낸 단면도이다.3 is a cross-sectional view showing a state in which the dial attached to the green tire vulcanization mold is projected to some extent as a conventional structure.

상기와 같은 목적을 달성하기 위하여 본 고안은, 그린타이어가 가류용 몰드의 사이드월상에 다수의 결합돌기를 구비한 함몰된 안착부가 형성되고 이 안착부에 끼워져 고정되는 문자판이 상기 안착부의 결합돌기와 결합되도록 함물된 다수의 결합홈을 갖춘 구조로 된다.In order to achieve the above object, the present invention, the green tire is formed with a recessed seating portion having a plurality of engaging projections on the sidewall of the mold for vulcanization and the dial that is fitted and fixed to the seating portion is combined with the engaging projection of the seating portion. It is a structure having a plurality of coupling grooves contained as possible.
이에 따라, 문자가 에칭된 문자판의 결합홈을 몰드의 사이드월에 형성된 안착부로 삽입하게 되면, 상기 결합홈에 안착부의 결합돌기가 끼워지면서 사이드월의 표면과 문자판의 표면이 일치하게 되므로 가류후 완성된 타이어 상에 단차가 발생하지 않고 정해진 위치에 균일한 문자가 찍히도록 되어진다.Accordingly, when the coupling groove of the letter-etched dial is inserted into the seating portion formed in the sidewall of the mold, the coupling protrusion of the seating portion is fitted into the coupling groove, so that the surface of the sidewall and the surface of the dial coincide with each other. A uniform character is imprinted on a fixed position without a step occurring on the used tire.
이하 본 고안은 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 따라 문자판을 타이어몰드 상에 부착한 상태를 나타낸 분리단면도이고 제2도는 문자판과 안착부의 세부확대도를 도시한 것인바, 그린타이어를 가류하는 몰드의 사이드월(1) 상에 소정깊이로 함몰되어 대략 역삼각형 형상으로 서로 일정간격을 두고 돌출된 다수개의 결합돌기(1b)와 문자판(2)의 고정위치를 정해주도록 한쪽 부위에 돌출되어 형성된 고정홈(1c)으로 이루어진 안착부(1a)가 형성되어, 이 안착부(1a)에 문자판(2)이 안착되되, 이 문자판(2)은 여러 가지 형상을 각인한 에칭문자(2a)가 형성된 면의 반대면으로 상기 안착부(1a)의 결합돌기(1b)와 끼워져 결합되도록 서로 대응되는 형상으로 이루어진 다수개의 결합홈(2b)과, 상기 고정홈(1c)에 삽입되어 문자판의 위치 내지 형상을 정확하게 잡아주는 고정부(2c)로 구성되어 진다.1 is a separated cross-sectional view showing a state that the dial is attached to the tire mold according to the present invention and FIG. 2 is a detailed enlarged view of the dial and the seating part, the side wall (1) of the mold vulcanizing the green tire A recess consisting of a fixing groove 1c protruding in one portion to determine a fixing position of the plurality of engaging projections 1b and the dial 2 protruded at a predetermined interval from each other in a substantially inverted triangle shape in a predetermined depth in the A portion 1a is formed so that the dial 2 is seated on the seating portion 1a, and the dial 2 is opposite to the surface on which the etching characters 2a are stamped in various shapes. A plurality of coupling grooves (2b) made of a shape corresponding to each other to be fitted and coupled to the coupling protrusion (1b) of (1a), and the fixing portion (2c) is inserted into the fixing groove (1c) to accurately grasp the position or shape of the dial It consists of).
따라서, 상기 문자판(2) 상의 고정부(2c)를 사이드월(1) 상에 형성되 안착부(1a)의 고정홈(1c) 위치에 맞도록 문자판(2)을 눌러 안착부(1a)에 삽입하여 취부하도록 되어, 문자판(2)과 사이드월(1)이 단차를 갖지 않는 평면을 구성하도록 된다.Therefore, the fixing part 2c on the dial 2 is formed on the side wall 1 and is pressed into the mounting part 1a by pressing the dial 2 so as to match the position of the fixing groove 1c of the seating part 1a. The dial 2 and the side wall 1 constitute a plane having no step.
이에 따라, 서로 끼워져 결합되는 결합돌기(1b)와 결합홈(2b)과 같은 결합매개를 이용하여 문자판(2)이 억지끼움식으로 끼워져 고정되므로 사이드월(1) 상에서 문자판(2)의 이동을 방지할 수 있으며, 가공정을 거쳐 완성된 타이어의 각인문자가 타이어의 다른 부분과 단차를 가지지 않게 된다.Accordingly, by using the coupling media such as the engaging projection (1b) and the coupling groove (2b) to be coupled to each other, the dial (2) is fitted to be fixed by fitting so that the movement of the dial (2) on the side wall (1) It can be prevented, and the carved letters of the finished tires will not have a step with other parts of the tire.
이상에서 설명한 바와 같이 본 고안에 의하면, 문자가 에칭된 문자판을 사이드월 상의 안착부에 삽입하도록 하여 문자판이 사이드몰드 상에서 움지깅는 것을 방지하며, 이에 따라 가류공정을 마친 완성된 타이어의 문자 각인 부분과 기타 부분의 단차가 없어지고 타이어상에 고정위치에 정확하게 문자가 찍히는 효과가 있다.As described above, according to the present invention, the letter-etched dial is inserted into the seating portion on the sidewall to prevent the dial from creeping on the side mold, and thus the letter stamped part of the finished tire after the vulcanization process The step of the other part is eliminated, and the effect is that the letters are accurately printed on the fixed position on the tire.
