본 발명은 타이어가류금형의 브라더성형방법과 장치에 관한 것이다.The present invention relates to a brother molding method and apparatus for a tire vulcanization mold.

타이어가류금형의 브라더는 첨부된 도면 제2도에 도시된 바와 같은 스러그(Slug)고무를 소정의 금형에 넣고 가열가압하여 제1도에 도시된 바와 같이 형성시킨다.The tire vulcanizing mold is formed by inserting a slug rubber as shown in FIG.

이와 같이 스러그고무를 가열가압하여 브라더를 제조함에 있어서 종래에는 제3도에 도시된 금형을 브라더의 성형장치로 사용하여 왔다.As described above, in manufacturing a brother by heating and pressing the slug rubber, a mold shown in FIG. 3 has been used as a molding apparatus of the brother.

이와같은 제3도에 도시한 금형은, 프레스기의 상판에 상하로 2분할된 외부금형의 상부(102)가 고정되게 설치되고, 내부금형(103)이 승강봉(104)에 고정설치되어 있으며, 내부금형(103)의 하단은 별도의 하단금형(1031)으로 분할되어 승강봉(1032)에 고정설치되고 외부금형의 하부(105)가 프레스기 하판에 고정설치되어 있다.In the mold shown in FIG. 3, the upper part 102 of the outer mold divided into two parts is fixed to the upper plate of the press machine, and the inner mold 103 is fixed to the lifting bar 104. The lower end of the inner mold 103 is divided into a separate lower mold 1031 and fixed to the lifting bar 1032, and the lower mold 105 of the outer mold is fixed to the lower plate of the press.

그리하여 외부금형의 하부(105)상면의 재치부(108)에 스러그고무(109)를 올려놓고 외부금형의 하부(105)를 상승시키면 스러그고무(109)는 내부금형(103)과 외부금형의 상하부(102,205) 사이의 브라더성형공간(110)으로 압입된다.Thus, when the slug rubber 109 is placed on the mounting portion 108 of the upper surface of the lower mold 105 and the lower portion 105 of the outer mold is raised, the slug rubber 109 is the inner mold 103 and the outer mold. It is press-fitted into the brother molding space 110 between the upper and lower portions 102,205.

그런데, 브라더성형공간(110)은, 하부(105)의 상승초기에는, 제3도의 (a)에 도시된 바와 같이, 윗공간(111)은 브라더의 상측형상과 동일한 형상을 가지는 반면 아랫공간(112)으로 더 많은 량이 압이보디게 마련이고 그리하여 브라더는 상부보다 하부가 보다 두꺼워지거나 적어도 고무밀도가 커지게 되는 일이 있으며 이와같이 브라더의 상하부의 두께나 밀도가 달라지게 되면 타이어가류시 타이어 상하부의 두께가 서로 달라지게 되어 타이어의 균일성에 큰 영향을 미치게 된다.However, the brother molding space 110, at the beginning of the lower portion 105, as shown in (a) of FIG. 3, the upper space 111 has the same shape as the upper shape of the brother while the lower space ( 112) the larger the amount of pressure, so the brother may become thicker than the upper part or at least the rubber density becomes larger. Thus, if the thickness or density of the upper and lower parts of the brother is changed, the upper and lower tires are subjected to tire vulcanization. The thickness of the different from each other will greatly affect the uniformity of the tire.

그리하여 본 발명은 스러그고무를 압입하는 초기에는 브라더성형공간의 상하부가 동일한 체적을 갖게하여 스러그고무가 상하 동일하게 압입되게 하므로서 브라더의 상하부 두께나 밀도를 동일하게 형성시키고 그리하여 가류성형되는 타이어의 균일성을 향상시키기도록 한 것인바, 이와같은 본 발명을 첨부된 도면에 의하여 설명하면 다음과 같다.Thus, in the present invention, the upper and lower portions of the brother molding space have the same volume at the initial stage of injecting the slug rubber so that the slug rubber is press-fitted equally up and down, thereby forming the same thickness and density of the brother and thus forming the vulcanized tire. It is to improve the uniformity bar, as described in the accompanying drawings, the present invention as follows.

본 발명은 제4도에 도시된 바와같이, 상측외부금형(1)과 하측외부금형(2) 및 2분할된 내부금형(3)으로 구성되고, 상하외부금형(1,2) 사이에 스러그고무(4)를 재치할 재치부(5)를 가지며, 상측외부금형(1)은 프레스기의 상판에 하측외부금형(2)은 프레스기의 하판에 각각 고정설치되고, 분할된 내부금형(3)의 상단중앙부와 분할된 내부금형의 하단중앙부가 각각 승강봉(6)(7)에 고정설치된 것에 있어서, 내부금형(3) 본체를 그 중간부위에서 상하로 2분할시켜 내부상금형(31)과 내부하금형(32)으로 형성시키고, 내부상하부금형(31,32) 사이에도 스러그고무(4)가 재치될 재치부(51)를 형성시키며 내부상금형(31)과 내부하금형(32) 이 내부하금형(32)의 내측상단주연에 상향으로 형성시킨 내접통체(8)에 의해 암수결합 되게 한다. 그리하여 제4도의 (a)에 도시된 바와 같이 상하외부금형과 상하내부금형 사이의 상하공간부(9,91)가 동일한 형상과 체적을 가지게 한다.As shown in FIG. 4, the present invention consists of an upper outer mold (1), a lower outer mold (2), and a divided inner mold (3), and a slug between the upper and lower outer molds (1,2). The upper outer mold 1 is fixed to the upper plate of the press machine, and the lower outer mold 2 is fixed to the lower plate of the press machine, respectively. The upper middle part and the lower middle part of the divided internal mold are fixedly installed on the elevating rods 6 and 7, respectively, and the inner mold 3 is divided into two parts up and down at the middle part thereof. It is formed as a lower mold (32), and between the upper and lower molds (31, 32) to form a mounting portion 51 on which the slug rubber (4) is to be placed, and the inner upper mold (31) and the inner lower mold (32) The inner lower mold 32 is male and female coupled by the inner circumferential body 8 formed upward in the upper peripheral edge. Thus, as shown in (a) of FIG. 4, the upper and lower space portions 9 and 91 between the upper and lower outer molds and the upper and lower inner molds have the same shape and volume.

상축외부금형(1)과 하측외부금형(2) 및 내부상금형(31)과 내부하금형(32)이 닫혀진 제4도의 (b)에 도시된 바와 같은 상태에서는 내부금형(3)의 내부공간(33)에 가열을 위한 고온의 수증기가 압입되는바 압입되는 수증기가 누출되지 아니하도록 결합 부위에 패킹(81)을 설치하는 것이 바람직하다.내부금형93)의 내부공간(33)에 수증기를 압입함에 있어서는 종래의 성형장치에 있어서와 같이 상하승강봉(6,7)의 중심에 설치한 통기공(61)을 통하여 이를 압입 배출시킨다.The inner space of the inner mold (3) in the state as shown in (b) of FIG. 4 in which the upper shaft outer mold (1), the lower outer mold (2), and the inner upper mold (31) and the inner lower mold (32) are closed. Since the high temperature steam for heating is pressed into the 33, it is preferable to install the packing 81 at the joining portion so as not to leak the pressurized steam. The steam is press-inserted into the inner space 33 of the inner mold 93. In the case, as in the conventional molding apparatus, it is press-injected and discharged through a vent hole 61 provided at the center of the up and down lifting rods 6 and 7.

이와 같은 본 발명은 상하측외부금형(1,2) 사이에 재치부(5,51)에 스러그고무(4)를 올려놓고, 상측외부금형(1)과 내부상금형(31)을 고정시킨 상태에서, 하측외부금형(2)과 내부하금형(32)을 동시에 상승시키면 스러그고무(4)가 브라더의 형상과 동일한 형상을 가지는 상하공간부(9)(91)에 고르게 압입된다.In the present invention, the slug rubber 4 is placed on the mounting parts 5 and 51 between the upper and lower outer molds 1 and 2, and the upper outer mold 1 and the inner upper mold 31 are fixed. In the state, when the lower outer mold 2 and the inner lower mold 32 are raised at the same time, the slug rubber 4 is evenly press-fitted into the upper and lower space portions 9 and 91 having the same shape as that of the brother.

따라서 본 발명은 상하의 두께나 밀도가 균일한 브라더를 제조할 수 있게 하고 그리하여 타이어의 균일성(Uniformity)을 크게 향상시킬 수 있는 효과가 있다.Therefore, the present invention enables the manufacture of a uniform thickness and density of the Brother, and thus has the effect of greatly improving the uniformity (Uniformity) of the tire.
