Description
본 고안은 타이어의 성형 금형에 설치되는 공기 배출변에 관한 것이다. 그린타이어를 성형금형에 넣고 그린타이어의 내부에 설치된 브라더에 공기를 압입시켜 팽창시키면 그린타이어의 외벽이 성형금형의 내벽에 닿아 금형의 내면 형상에 따라 타이어의 외형이 성형된다. 그런데 브라더를 팽창시키더라도 금형과 그린타이어 사이에 공기가 잔존하게 되면 타이어가 금형에 밀착되지 못하게 되어 성형 작업이 부전하게 되는 염려가 있다. 그리하여 그린타이어와 금형사이의 공기를 배출시키기 위한 배출변이 안출되어 금형의 내면에 장착되어 사용되고 있다(본 출원인의 실용신안등록 제67706호; 공보번호 92-4862호). 그러나 이와같은 공기 배출변들은 몸체의 내부에 스프링으로 작동되는 변체를 설치하여 구성되어 있으며, 이러한 변체는 내측으로 출몰되므로 변좌에 고무가 끼이게 되어 작용 부전이 일어나는 일이 있을 뿐 아니라 타이어에 흠집을 만드는 결점이 있다.The present invention relates to an air discharge valve installed in a molding die of a tire. When the green tire is placed in a molding mold and air is inflated by injecting air into the brother installed inside the green tire, the outer wall of the green tire contacts the inner wall of the molding mold, and the outer shape of the tire is molded according to the inner surface shape of the mold. However, even when the brother is inflated, if air remains between the mold and the green tire, the tire may not come into close contact with the mold, thereby causing the molding work to fail. Thus, a discharge valve for discharging air between the green tire and the mold is devised and mounted on the inner surface of the mold (Utility Model Registration No. 67706 of the present applicant; Publication No. 92-4862). However, such air discharge valves are constructed by installing a spring-operated valve inside the body, and the valves are mounted on the inside, so the rubber becomes stuck in the toilet seat, which causes malfunction, as well as scratches the tire. There is a drawback to making.
그리하여 본 고안은 타이어 성형용 금형에 있어서의 공기 배출에 관한 전술한 문제점을 해결하기 위해 안출된 것으로서, 본 고안은 변체의 주연과 변체의 중심에 설치하는 마개의 주연에 고무는 통과하지 못하고 공기만이 통과할 수 있는 미세한 통기공을 설치하므로서 공기의 배출효과를 증진시키고 특히 변체로 인한 타이어 표면에의 흠집 발생이나 변체의 작용 부전으로 인한 식출의 발생을 감소시킬 수 있도록 안출된 것으로 이를 첨부된 도면에 의하여 설명하면 다음과 같다.Therefore, the present invention was devised to solve the above-mentioned problems related to the air discharge in the mold for forming a tire, and the present invention is intended to solve the above problem. It is designed to enhance the air discharge effect and to reduce the occurrence of scratches on the tire surface due to the deformation or the occurrence of extraction due to the malfunction of the deformation due to the installation of fine ventilation holes that can pass therethrough. Explained as follows.

본 고안은 첨부된 도면에 도시된 바와 같이, 중앙에 통공(11)과 렌치홈(12)이 형성되고 외주부에 결합 나사부(13)가 형성된 몸체(1)에 마개(2)를 설치하여서 된 것에 있어서, 몸체(1)의 외주연에 직경이 0.01~0.05m인 통기구(通氣溝)(14)를 길이 방향으로 형성시키고, 또한 몸체(1)와 마개(2) 사이에 직경이 0.01~0.5mm인 통기공(21)을 설치하는 것을 특징으로 한다. 통기구(14)나 통기공(21)의 직경을 0.01~0.05mm로 형성시키는 것은 공기의 유통은 자유로우나 고무입자 등의 통과가 불가능하게 하기 위함이다. 다만 마개(2)는 그 중앙부의 두께를 얇게 형성시켜 중앙부분에 타력을 가하므로서 마개를 파손시키고 몸체(1)의 렌치홈(12)에 렌치를 끼워 몸체(1)를 발출할 수 있게 하는 것이 바람직하다.The present invention, as shown in the accompanying drawings, the through-hole 11 and the wrench groove 12 is formed in the center and the stopper (2) is installed on the body (1) formed with a coupling screw portion 13 in the outer peripheral part In the outer periphery of the body 1, a vent 14 having a diameter of 0.01 to 0.05 m is formed in the longitudinal direction, and the diameter is 0.01 to 0.5 mm between the body 1 and the stopper 2. It is characterized by installing a phosphorus vent 21. The diameter of the air vent 14 and the air vent 21 is formed to be 0.01 ~ 0.05mm to allow the air to flow freely, but to prevent the passage of rubber particles. However, the stopper (2) is to form a thin thickness of the center portion to break the stopper by applying a force to the center portion to insert the wrench into the wrench groove 12 of the body (1) to be able to eject the body (1) desirable.
통기구(14)나 통기공(21)은 외방으로 연통되어야 한다. 다만 그 연통하는 길은 따질 바 아니다. 따라서 본 고안은 전술한 통기구나 통기공에 관한 구성에 있어서, 상술한 바 또는 첨부된 도면에 도시된 바의 실시예에 국한되지 않고 본 고안의 기술사상이 허용하는 범위 내에서 다양하게 변형하여 실시될 수가 있다.Vent 14 or vent 21 should be communicated outward. The path of communication is not to be determined. Therefore, the present invention is not limited to the embodiments described above or shown in the accompanying drawings in the configuration related to the above-described vents or vents, various modifications are carried out within the range allowed by the technical idea of the present invention. Can be.
이상에서와 같이 구성된 본 고안에 따르면 변체에 형성되는 통기구나 통기공이 미세하여 고무의 식출 염려가 없을 뿐 아니라 통기구나 통기공의 직경이 워낙 미세하여 이에 고무입자가 몰입되지 아니하여 통기구나 통기공이 폐색될 염려가 없게 되는 효과가 있다.According to the present invention configured as described above, there is no fear of extraction of rubber because the vent or vent formed in the body is fine, and the diameter of the vent or vent is so fine that rubber particles are not immersed in the vent or vent. There is an effect that there is no fear of being blocked.
