Description

타이어 가류금형의 에어벤트 장치{An air vent device for tire mould}Air vent device for tire vulcanization mold

본 고안은 타이어 가류금형의 에어벤트 장치에 관한 것으로, 특히 타이어 제조시 사용되는 가류금형에 구비된 관통홀에 끼어박음식으로 결합되며 내측에는 공기가 유통되는 다수개의 세관(작은 홀)이 구비된 에어벤트 장치에 관한 것이다.The present invention relates to an air vent device of a tire vulcanization mold, and in particular, is coupled to the through-holes provided in the vulcanization mold used in the manufacture of tires, and has a plurality of customs (small holes) inside which air is distributed. An air vent device.

일반적으로 타이어를 제조하는 공정은 상, 하로 구성된 금형내에 타이어의 원료인 고무를 장입시킨 후 외부금형과 내측의 코아간에 가압 및 가열하여 타이어 형상을 성형하고 있다.In general, a tire manufacturing process is performed by charging rubber, which is a raw material of a tire, into a mold consisting of upper and lower parts, and pressing and heating an outer mold and an inner core to form a tire shape.

상술한 제조공정 중 가압 및 가열공정에서 고무와 금형내에 잔존하는 공기는 외부로 배출시켜 주어야 되며, 이러한 공기가 배출되지 않고 내부에 잔존하는 경우에는 타이어에 핀 홀 발생이나 공기흐름에 따른 자욱이 발생되어 타이어의 구조적인 불량이나 외관상의 불량을 발생시키게 된다.The air remaining in the rubber and the mold in the pressurizing and heating process of the above-mentioned manufacturing process should be discharged to the outside, and when such air is not discharged and remains inside, tires are generated due to pin hole generation or air flow. Structural defects and appearance defects of tires are generated.

따라서, 타이어의 가열, 가압 공정에서 금형내의 공기를 외부로 배출시키기 위한 장치가 필요하게 되는데, 종래에는 금형내의 공기를 배출하기 위한 수단으로도 1에 도시된 바와 같이, 금형을 관통하는 관통홀에 끼어 박음식으로 결합되며 내측에 0.6mm의 에어벤트홀(1)이 구비된 에어벤트장치(2)가 사용되어 왔으나 이는 공기와 함께 고무가 동시에 배출되는 단점이 있었으며, 고무의 빨려나옴에 의해 에어벤트홀(1)이 막혀 수회작업 후에는 에어벤트홀(1)을 관통시켜야 하는 문제점이 있었다.Therefore, there is a need for a device for discharging air in the mold to the outside during the heating and pressurization process of the tire, conventionally as a means for discharging the air in the mold, as shown in Figure 1, through the through-hole penetrating the mold The air vent device (2) having a 0.6 mm air vent hole (1) coupled to the inside of the food has been used but this has the disadvantage that the rubber is discharged at the same time with the air, the air is sucked out of the rubber There was a problem in that the vent hole 1 was blocked and penetrated through the air vent hole 1 after several operations.

또한, 본 출원인에 의해 출원되어 등록(등록번호 20-0209439)된 도 2와 같은 기술에 있어서는 내측에 다수개의 작은 에어벤트홀(3)이 구비된 에어벤트장치(4)를 사용함으로써 기존의 1개의 큰 에어벤트홀(1)이 구비된 에어벤트장치(2)에 비해 에어벤트시 에어와 동시에 고무가 배출됨으로써 발생되던 타이어의 구조적 불량과 외관상의 불량을 방지할 수 있었으나, 이 경우 장기적으로 사용시 작은 에어벤트홀(3)중 일부가 막히게 되는 단점이 있었다.In addition, in the technique as shown in FIG. 2 filed and registered by the present applicant (Registration No. 20-0209439), the existing air vent apparatus 4 having a plurality of small air vent holes 3 inside is used. Compared to the air vent device 2 having two large air vent holes 1, it was possible to prevent structural defects and appearance defects of the tire caused by the discharge of rubber at the same time of air venting. There was a disadvantage that some of the small air vent hole (3) is blocked.

본 고안은 상기와 같은 종래의 문제점들을 해결하기 위한 것으로, 본 고안의 목적은, 0.2mm이하의 다수관을 결합 가공하여 형성된 내부관을 일정길이 이하로 절단하여 외부관에 삽입하거나 용접, 나사체결 등의 방법으로 결합하여 구성된 에어벤트 장치를 제공하여 공기의 원활한 소통과 고무의 배출방지로 타이어 표면을 개선한 환경친화적인 타이어를 제조할 수 있도록 하는데 있다.The present invention is to solve the conventional problems as described above, the object of the present invention is to cut the inner tube formed by combining a plurality of pipes of 0.2mm or less to a certain length or less to insert into the outer tube or welded, screwed By providing an air vent device configured by combining in such a way as to enable the production of environmentally friendly tires with improved tire surface by the smooth communication of air and preventing the discharge of rubber.

이와 같은 목적을 달성하기 위한 본 고안의 제조과정은, 외부관을 제조하는 단계와, 여러개의 세관을 결합하여 인발가공한 내부관을 제조하는 단계와, 제조된 내부관을 길이방향으로 절단가공하여 절단내부관을 제조하는 단계와, 절단 내부관을 외부관에 결합하는 단계로 이루어진다.The manufacturing process of the present invention for achieving the above object, the step of manufacturing the outer tube, the step of manufacturing the inner tube is drawn by combining a plurality of tubules, by cutting the manufactured inner tube in the longitudinal direction And a step of manufacturing the cut inner tube, and coupling the cut inner tube to the outer tube.

이하, 본 고안의 실시 예를 첨부도면을 참고로 하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 고안의 분해사시도, 도 4는 본 고안의 결합사시도로, 내부관에 다수개의 세관(30)을 나란하게 삽입 및 압축결합하여 인발 가공하고 이를 소정길이 절단하여 절단내부관(50)을 형성하며, 상기 절단내부관(50)을 외부관(10)에 삽입하여 구성된 것으로, 도면중 60은 에어벤트장치를 나타낸 것이다.3 is an exploded perspective view of the present invention, Figure 4 is a combined perspective view of the present invention, a plurality of tubules 30 are inserted into the inner tube side by side and compression-combined by drawing and cutting the predetermined length to cut the inner tube (50) To form, it is configured by inserting the cut inner tube 50 into the outer tube 10, 60 in the figure shows an air vent device.

단, 상기 절단내부관(50)을 외부관(10)에 결합하는 수단으로는 삽입가공, 용접, 나사체결 등을 사용할 수 있다.However, as the means for coupling the cut inner tube 50 to the outer tube 10, insertion processing, welding, screwing, or the like may be used.

이와 같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

먼저, 내부관내부에 다수의 세관(30)을 결합하여 압축 인발함으로써 결합이 견고하게 되며, 이를 일정길이로 절단하여 절단내부관(50)을 만든 상태에서 이러한 절단내부관(50)을 외부관(10)의 내면에 삽입가공하거나 용접, 나사체결 등의 방법으로 결합하여 타이어 가류금형에 삽입 결합되는 형상을 갖는 에어벤트 장치(60)로이루어진다.First, by combining a plurality of tubules (30) in the inner tube by compression drawing is a strong bond, cutting the inner tube 50 in a state made by cutting it to a certain length by cutting the inner tube 50 to the outer tube An air vent device 60 having a shape that is inserted into the tire vulcanization mold by inserting into the inner surface of the 10 or by joining by welding, screwing, or the like is formed.

따라서, 본 고안의 에어벤트장치(60)를 타이어 금형에 결합하여 작업시 다수개의 세관(30)이 형성되어 있고, 이 세관(30)의 길이가 짧으므로 타이어 생산시 고무가 세관(30)에 막히지 않게 된다.Therefore, when the air vent device 60 of the present invention is combined with a tire mold, a plurality of tubules 30 are formed during operation, and the length of the tubules 30 is short, so that rubber is produced in the tubules 30 during tire production. It will not be blocked.

한편, 내부관과 외부관(10)에 사용되는 재질은 금속제품으로 성형성이 좋은 동합금이나 스테인리스, 니켈합금, 철, 티타늄파이프나 2원계 이상의 합금이나 또는 내열성이 좋고 열팽창계수가 극히 낮은 플라스틱으로 하여도 좋다.On the other hand, the material used for the inner tube and the outer tube 10 is a metal product, which is a moldable copper alloy, stainless steel, nickel alloy, iron, titanium pipe or an alloy of two or more systems, or a plastic having excellent heat resistance and extremely low coefficient of thermal expansion. You may also do it.

또한, 내부관과 외부관(10)에 사용되는 재질은 동일소재이거나 다른 재질의 소재이어도 무방하며, 내부관과 외부관(10)의 형상은 원형의 파이프가 좋고, 타원형, 다각형이어도 좋으나 작업성을 고려할 경우 원형 파이프가 바람직하다.In addition, the material used for the inner tube and the outer tube 10 may be the same material or a different material. The inner tube and the outer tube 10 may have a circular pipe shape, an oval shape, or a polygon shape. Considering this, round pipes are preferable.

인발가공이 완료된 외부관(10)의 치수는 타이어 생산용 금형에 좌우되나 일반적으로 외경1-50mm, 두께 0.1-20mm 내부관이 내주면에 결합된 세관(30)의 치수는 내경이 0.01-10mm인 다수의 세관이 사용되며, 절단내부관(50)의 길이는 5mm이하로 하는 것이 바람직하다.The dimension of the outer tube 10 after the drawing process is completed depends on the mold for tire production, but generally the dimension of the outer tube 1-50 mm and the thickness 0.1-20 mm of the inner tube combined with the inner circumferential surface is 0.01-10 mm. A plurality of tubules are used, the length of the cut inner tube 50 is preferably 5mm or less.

이상에서 상세히 설명한 바와 같은 본 고안은 종래 1개의 큰 에어벤트홀이 구비된 장치나 또는 외부관의 내부에 다수의 세관을 결합하여 벤트홀 길이가 외부관의 길이와 같은 에어벤트장치는 에어벤트시 에어와 동시에 고무가 배출되거나 또는 장시간 사용시 막힘발생으로 타이어의 표면불량을 발생시켰으나 본 고안에서는 내면에 다수개의 작은 세관이 구비된 에어벤트장치의 길이를 짧게 절단하여 외부관에 결합함으로써 상기 종래의 결점을 모두 해소함은 물론, 고무 배출로 발생되는 공해유발을 방지할 뿐 만 아니라 값비싼 수입고무의 절감효과가 있다.The present invention, as described in detail above, is conventionally provided with a device having one large air vent hole or an air vent device having a vent hole length equal to the length of an outer tube by combining a plurality of tubules inside the outer tube. At the same time, the rubber is discharged at the same time as the air or clogging caused when used for a long time, but the surface defect of the tire was generated, but in the present invention, by short cutting the length of the air vent device equipped with a plurality of small tubules on the inner surface and coupled to the outer tube, the conventional drawback In addition to eliminating all of them, it not only prevents pollution caused by rubber discharge, but also saves expensive imported rubber.
