본 발명은 전차(TANK)류의 로드휠(ROAD WHEEL) 고무성형장치에 관한 것이다.The present invention relates to a road wheel (ROAD WHEEL) rubber molding apparatus of the tank (TANK).
전차(TANK)류에 사용되는 로드휠에는 접촉되는 면과의 완충작용을 이룰 수 있도록 고무를 성형하게 되어 있는바, 종래에는 로드휠에 고무를 성형하는 수단으로 일정한 두께와 폭을 갖도록 띠현상의 고무띠를 별도로 압출시켜 놓은 다음, 로드휠에 가류성형시킬때에는 제 1 도에 도시된 바와 같이 금형기기의 하부금형(3)에 고무를 성형시킬 로드휠(1)을 얹혀놓고 로드휠(1) 둘레에 상기 고무띠를 두르게 한 다음 상부금형(2)과 하부금형(3)으로 기류성형하게 되었다.The road wheels used for tanks are molded with rubber to achieve a buffering effect on the contact surface. Conventionally, the rubber bands are formed to have a certain thickness and width as means for forming rubber on the road wheels. When separately extruded, and then subjected to vulcanization on the rod wheel, as shown in FIG. 1, the rod wheel 1 for molding the rubber is placed on the lower mold 3 of the mold machine, and the rubber band is formed around the rod wheel 1. Then, air flow was formed into the upper mold (2) and the lower mold (3).
이와 같이 종래에는 가류성형시키기 위해서는 고무띠를 성형해야 하는 별도의 공정이 필요할뿐만 아니라, 성형에 따른 고무의 필요양보다 약간 많은 양의 고무띠를 사용해야 되는 로스(LOSS)의 발생과, 가류성형 된 다음에도 제품외면에 붙어 있는 고무찌꺼기를 제거해야하는 사상공정이 추가되어야만 했다.As described above, in order to vulcanize molding, not only a separate process of forming a rubber band is required, but also a generation of LOSS, which requires the use of a slightly larger amount of rubber band than the amount of rubber required for molding, Next, a finishing process to remove the rubber residue from the outside of the product had to be added.
따라서, 본 발명은 상기와 같은 여러 결점을 감안하여 발명한 것으로, 로드휠에 고무를 성형시키는 수단으로 금형틀에 고무를 주입시켜서 가류성형될 수 있도록 함으로써 고무의 손실을 줄이고, 한번의 공정으로 가류성형될 수 있도록 한 것이다.Therefore, the present invention has been invented in view of the above-mentioned shortcomings, by injecting rubber into the mold as a means for forming rubber in a road wheel, so that it can be vulcanized, thereby reducing the loss of rubber and vulcanizing in one step. It would be possible.
이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.When described in detail based on the accompanying drawings as follows.
로드휠(1)에 고무를 가류성형하기 위한 상부금형(2)과 하부금형(3)으로 이루어진 금형기기에 있어서, 상부금형(2)의 중간에 단열판(5)과 히터층(6)을 이루게 하고, 상부에는 포트(POT : 7)를 형성하여 고무를 담을 수 있게 하며 포트(7) 하부에 노즐(8)을 형성하여 상기 단열판(5)과 히터판(6)을 통해 사출홈(9)에 연통되게 ; 하며, 상부금형(2) 상부에는 코어(10)를 구비한 프레스부(4)를 상하 작동되게 설치하여 코어(10)가 포트(7)내에 고무를 압축시킴에 따라 노즐(8)를 통해 사출홈(9)에 주입될 수 있도록 구성된 로드휠 고무성형 장치이다.In a mold apparatus consisting of an upper mold (2) and a lower mold (3) for vulcanizing rubber on a road wheel (1), the heat insulating plate (5) and the heater layer (6) are formed in the middle of the upper mold (2). In the upper part, a port (POT: 7) is formed to contain the rubber, and a nozzle 8 is formed at the lower part of the port 7 to the injection groove 9 through the heat insulating plate 5 and the heater plate 6. In communication; In the upper mold 2, the press part 4 having the core 10 is installed to operate up and down, so that the core 10 compresses the rubber in the port 7 and is injected through the nozzle 8. It is a road wheel rubber forming apparatus configured to be injected into the groove 9.
여기서 포트(7)의 내부 둘레에는 플랜지(11)를 설치하여 프레스부(4)의 상하작동에 따라 코어(10)가 포트(7)에 담아 있는 고무를 압입하게 될때 코어(10)와 포트(7) 사이의 틈으로 고무가 올라오는 것을 방지할 수 있게 하였으며, 따라서 고무가 더욱 효과적으로 압입되어지는 것이다.Here, the inner periphery of the port 7 is provided with a flange 11 when the core 10 presses the rubber contained in the port 7 according to the up and down operation of the press part 4. 7) It is possible to prevent the rubber from rising to the gap between them, so that the rubber can be pressed more effectively.
또한, 포트(7)와 사출홈(9) 사이는 노즐(8)에 의해 연통되어 있어서 포트(7)에 담아진 고무가 코어(10)에 의해 압입되어지면 노즐(8)을 통하여 사출홈(9)에 장입된다.In addition, the port 7 and the injection groove 9 are communicated by the nozzle 8 so that when the rubber contained in the port 7 is press-fitted by the core 10, the injection groove ( It is charged in 9).
이와 같이 고무를 주입시키는 포트(7)와 노즐(8)은 본 금형기기에 다수 형성하게 되며, 프레스부(4)의 한번에 동작으로 하부의 사출홈(9)에 고무가 일정량만큼 장입되는 것이다.In this way, a plurality of ports 7 and nozzles 8 for injecting rubber are formed in the present mold machine, and the rubber is inserted into the lower injection groove 9 by a predetermined amount by a single operation of the press unit 4.
이와 같이 구성된 본 발명은 하부금형(3)에 로드휠(1)을 엊혀 높고 하부금형(3)과 상부금형(2)을 밀착시킨 다음, 프레스부(4)를 하강시켜 포트(7)에 담아 있는 고무를 코어(10)로 압입하게 되며, 포트(7)내의 고무는 노즐(8)을 통하여 아래로 밀려 내려가게 된다.According to the present invention configured as described above, the rod wheel 1 is squeezed to the lower mold 3 so that the lower mold 3 and the upper mold 2 are in close contact with each other, and then the press part 4 is lowered to be contained in the port 7. The rubber is pressed into the core 10, and the rubber in the port 7 is pushed down through the nozzle 8.
이때 포트(7)의 내부둘레에는 플랜지(11)가 형성되어 있어서 포트(7)와 코어(10)사이로 빠져나오는 고부를 막게 되므로 효과적으로 압입되어지는 것이다.At this time, since the flange 11 is formed in the inner circumference of the port 7 to prevent the high part exiting between the port 7 and the core 10, it is effectively press-fitted.
노즐(8)을 따라 내려오는 고무는 중간의 히터층(6)을 지남에 따라 액화상태로 되어지면서 하부의 사출홈(9)에 장입되어지는 것이다.The rubber coming down along the nozzle 8 is charged into the lower injection groove 9 while becoming liquefied as it passes through the intermediate heater layer 6.
따라서, 사출홈(9)에 장입되어진 고무는 사출홈(9)의 형상으로 성형되어지면서 로드휠(1)에 가류성형되어지는 것이다.Therefore, the rubber charged into the injection groove 9 is vulcanized into the rod wheel 1 while being molded into the shape of the injection groove 9.
이와 같은 상태에서 사출홈(9)에 장입된 액화상태의 고무는 상기 로드휠(1)에 성형된 상태에서 굳어지게 되며, 일정시간이 지난후 상부금형(2)으로부터 하부금형(3)이 떨어지게 되면 작업자는 하부금형(3)상의 가류성형된 로드휠(1)을 꺼집어 내기만 하면 된다.In such a state, the liquefied rubber inserted into the injection groove 9 is hardened in the state formed in the rod wheel 1, and after a predetermined time, the lower mold 3 falls from the upper mold 2. The operator only needs to pull out the vulcanised rod wheel 1 on the lower mold 3.
이와 같이 본 발명은 하부금형(3)에 로드휠(1)을 얹혀 놓기만 하면 자동으로 고무가 적정량 주입되어져 로드휠(4)에 가류성형 되는 것이다.As described above, the present invention is simply placing the rod wheel 1 on the lower mold 3 to automatically inject a proper amount of rubber into the rod wheel 4 to vulcanize the rod wheel 4.
따라서, 로드휠(1)에 적정량의 고무가 주입되어 가류성형됨에 따라 종래의 성형될 고무량보다 많은 여분이 있는 고무를 넣어야 하는 고무의 손실을 줄일 수 있는 동시에 한번에 공정으로 가류성형될 수 있게 되므로 공수절감과 생산비를 절약할 수 있는 특장점이 있는 것이다.Therefore, since a suitable amount of rubber is injected into the road wheel 1 and subjected to vulcanization, it is possible to reduce the loss of rubber, which requires a lot of excess rubber than conventional rubber to be molded, and at the same time, it can be vulcanized by the process at a time. There is a merit that saves and saves production costs.
