By cutting the ring body of the unit and finishing processing the ring body of the cut unit with a grinding device to produce the rubber packing as a finished product, fundamentally to smoothly perform the essential function of the rubber packing to increase the reliability of the product, Furthermore, the present invention relates to a rubber packing manufacturing method having a circular cross section so that a rubber packing manufacturing process is automatically performed, thereby improving productivity and reducing a defective rate.

일반적으로 자동차의 엔진룸에는 엔진을 냉각하여 과열을 방지하는 동시에 적온으로 유지케 하는 냉각장치가 설치되어 있고, 이 냉각장치를 이루는 부품의 하나인 라디에이터 상,하부에는 냉각수가 흐르는 상부탱크와 하부탱크가 각각 설치되어 있으며, 이 라디에이터와 상,하탱크 사이에는 기밀성을 유지하기 위한 수단으로 고무패킹이 결합되어 있다.Generally, a cooling device is installed in an engine room of a car to prevent the engine from overheating and keep it at an appropriate temperature. The upper and lower tanks, through which coolant flows, are provided on the upper and lower parts of the radiator, which is one of the components of the cooling device. Are respectively installed, and the rubber packing is coupled between the radiator and the upper and lower tanks as a means for maintaining airtightness.

이와 같은 목적으로 사용되는 종래 고무패킹의 제조과정을 간단하게 살펴보면 먼저 금형틀(도시하지 않음)에 형성된 성형공간에 고무원재료를 투입한 후 열가압 성형하면 제1도에서와 같이 단면이 원형인 단위의 고무패킹(1)이 성형된다.Looking briefly at the manufacturing process of the conventional rubber packing used for this purpose, if the rubber raw material is first put into the molding space formed in the mold (not shown), and then thermo-pressure molding, the unit having a circular cross section as shown in FIG. Rubber packing 1 is molded.

상기와 같이 열가압 성형된 고무패킹(1) 안쪽과 바깥쪽 중간에는 금형의 파팅 라인에서 바리(2)가 발생하게 되는데 이때 마무리 작업으로 바리(2) 제거작업을 하고, 바리(2)가 제거된 고무패킹(1)을 라디에이터와 상,하탱크 사이에 결합하여 기밀성을 유지토록 하였다.Barrier (2) is generated in the parting line of the mold in the middle of the inside and the outside of the rubber packing (1) heat-molded as described above, the barrier (2) is removed as a finishing operation, the barrier (2) is removed Rubber packing (1) was bonded between the radiator and the upper and lower tanks to maintain airtightness.

이러한 종래 고무패킹 제조방법을 통하여 제조된 고무패킹(1)을 이용하여 라디에이터와 상하탱크 사이에 결합하여 사용할 수는 있으나 다음과 같은 문제점이 발생되었다.Using the rubber packing (1) manufactured by the conventional rubber packing manufacturing method can be used in combination between the radiator and the upper and lower tanks, but the following problems occur.

첫째, 금형틀의 성형공간에서 열가압 성형되는 고무패킹(1)은 금형의 파팅 라인에 의해 제1도에서와 같이 안쪽과 바깥쪽 중간에서 바리(2)가 형성하게 되고, 이러한 바리(2)는 필수 마무리 작업에 해당된다. 이를 위해 종래에는 수작업을 통하여 고무패킹(1) 한 개씩 바리(2) 제거작업을 수행하였기 때문에 생산성이 크게 저하되었고, 이러한 바리(2) 제거작업은 숙련공에 의해 제거작업이 이루어질 뿐 아니라 숙련공에 의해 바리제거 작업이 이루어진다 하더라도 잘못하면 고무패킹(1)에 흠집이나 불량률이 발생되는 요인이 되었다.First, the rubber packing (1) that is heat-pressurized in the molding space of the mold frame is formed with a bar (2) in the middle of the inside and the outside as shown in Figure 1 by the parting line of the mold, such a bar (2) Corresponds to the essential finishing work.
