본 발명은 고압주조기 플런저 팁 분해 장치에 관한 것으로서, 더욱 상세하게는 고압주조 과정에 있어서 플런저 팁과 슬리브의 마찰로 인해 발생되는 플런저 팁의 마모 로 이 플런저 팁을 주기적으로 교체할 수 있도록 마련된 고압주조기 플런저 팁 분해 장치에 관한 것이다.The present invention relates to a high pressure casting machine plunger tip disassembly apparatus, and more particularly, a high pressure casting machine provided to periodically replace the plunger tip due to abrasion of the plunger tip caused by friction between the plunger tip and the sleeve during the high pressure casting process. Plunger tip disassembly apparatus.

일반적으로, 고압 주조 공법은 사출슬리브내에 용탕을 넣고 플런저팁을 고속으로 전진시켜 용탕을 금형내에 사출하는 주조법으로써, 도 1에 도시된 바와 같이, 슬리브(10)내 채워진 용탕을 금형(20)의 성형부(21)에 주입하기 위해 사출부(30)를 작동시키면 사출실린더(40) 내부에 있던 사출실린더 로드(41)가 전진함에 따라, 이 사출실린더 로드(41)와 연결되어 있는 플런저로드(51) 또한 전진하게 되고 이 플런저로드(51) 최전방에 위치한 플런저 팁(50)은 슬리브(10)내 충진된 용탕을 밀면서 금형(20)내 성형부(21)으로 사출하게 된다.In general, a high pressure casting method is a casting method in which a molten metal is injected into a mold by injecting a molten metal into an injection sleeve and advancing the plunger tip at a high speed. As shown in FIG. When the injection unit 30 is operated to inject into the molding unit 21, the injection cylinder rod 41 inside the injection cylinder 40 is advanced, so that the plunger rod connected to the injection cylinder rod 41 ( 51) Also, the plunger tip 50 located at the forefront of the plunger rod 51 is injected into the mold 21 in the mold 20 while pushing the molten metal filled in the sleeve 10.

상기와 같은 작동으로 상기 플런저 팁은 슬리브를 왕복 이동하면서 마찰이 발생되고, 이러한 반복된 작용으로 인해 플런저 팁의 마모가 발생되어 지며, 플런저 팁의 마모에 따른 주기적인 교체가 이루어진다.In this operation, the plunger tip is frictionally generated while reciprocating the sleeve, and this repeated action causes wear of the plunger tip, and periodic replacement is performed according to the wear of the plunger tip.

도 2에서 보듯이, 작업자는 상기 플런저 팁(50)을 교체하기 위해 플런저 팁(50)을 전진시켜 금형(20) 외부로 돌출시킨 후, 작업공구를 이용해 상기 플런저로드(51)에 체결된 볼트 및 너트를 약간 푼 후, 작업자는 손으로 플런저 팁(50)을 돌려 플런저로드(51)와 분해하게 된다.As shown in FIG. 2, the operator advances the plunger tip 50 to protrude outside the mold 20 to replace the plunger tip 50, and then bolts fastened to the plunger rod 51 using a work tool. And after loosening the nut slightly, the operator turns the plunger tip 50 by hand to disassemble the plunger rod 51.

그러나, 상기와 같은 종래의 플런저 팁 분해 방식은 다음과 같은 문제점이 있었다.However, the conventional plunger tip disassembly method as described above has the following problems.

상기 플런저 팁은 그 중량이 20Kg의 무거운 구성부품이며 이 플런저 팁을 손으로 중심을 잡으면서 회전시키는 것은 작업자에게 상당한 노동강도를 요하게 되는 것으로써, 플런저 팁 분해 말기에 플런저 팁의 하강 사고가 발생되어 작업자의 안전사고가 유발될 수 있는 문제점이 있었다.The plunger tip is a heavy component weighing 20 kg and rotating the plunger tip while centering it by hand requires considerable labor intensity for the operator, resulting in a plunger tip falling accident at the end of disassembling the plunger tip. There was a problem that can cause worker safety accidents.

본 발명은 상기와 같은 문제점을 해결하기 위해 제안된 것으로서, 기존의 작업자가 손으로 직접 회전시켜 분해하던 플런저 팁을 분해 장치를 이용하여 분리함에 따라 작업자에게 노동강도를 요하지 않을 뿐 아니라 플런저 팁의 분해 말기에 발생되는 하강사고를 예방할 수 있는 고압주조기 플런저 팁 분해 장치를 마련하는데 그 목적이 있다.The present invention has been proposed in order to solve the above problems, by separating the plunger tip that was previously disassembled by rotating by hand by using a disassembly device does not require the labor intensity of the operator as well as disassembly of the plunger tip The purpose of the present invention is to provide a high pressure casting machine plunger tip disassembly device which can prevent the falling accident occurring at the end.

상기 샤프트(100) 후단부에는 이 샤프트(100)를 회전시키는 회전수단인 토오크 랜치(400)이 설치된다.The rear end of the shaft 100 is provided with a torque wrench 400 that is a rotation means for rotating the shaft 100.

또한, 상기 클램프(300)는 그 선단부에 구비된 집개부(310)가 플런저 팁(50)의 후단부를 잡아당겨 그 선단부가 상기 몸체(200)에 밀착될 수 있도록 5절 링크 구조의 타입으로 구성된다.In addition, the clamp 300 is configured in the form of a five-section link structure so that the front end portion is in close contact with the body 200 by pulling the rear end of the plunger tip 50 is provided with the catch portion 310 provided at the front end portion thereof. do.

상기 클램프(300)의 5절링크 구조는 선답부가 플런저 팁(50)을 잡아당기는 집게부(310)와 이 집게부(310) 후방 양측에 각각 회동 가능하게 그 일단부가 설치되는 제1링크(320) 및 제2링크(330)와, 이 제2링크(330)의 타단부는 상기 몸체의 전방부분에 회동가능하게 설치되며, 상기 제1링크(320)의 중심부분에는 상기 몸체(200)와 연결되도록 회동가능하게 설치된 제3링크(340)로 구성된다.The five-section link structure of the clamp 300 has a first part 320 having one end portion rotatably installed at both sides of the tong portion 310 to which the front portion pulls the plunger tip 50 and both sides of the rear portion of the tong portion 310. ) And a second link 330, and the other end of the second link 330 is rotatably installed in the front portion of the body, the central portion of the first link 320 and the body 200 and It is composed of a third link 340 rotatably installed to be connected.

이하에서, 본 발명에 따른 고압주조기 플런저 팁 분해 장치의 작동상태를 설명한다.Hereinafter, the operating state of the high pressure casting machine plunger tip disassembly apparatus according to the present invention.

고압주조기의 슬리내(10) 내부를 왕복 운동하면서 슬리브(10) 내부에 충진된 용탕을 금형(20) 내부로 밀어주는 플런저 팁(50)의 마모로 인해 플런저 팁(50)을 교체하기 위해서는 플런저 팁(50)을 전진시켜 금형(20) 외부로 돌출시키고 난 후, 크래인(130)을 이용해 샤프트(100) 외면에 설치된 베어링(110)의 걸림부(120)를 고정시키면, 작업자는 금형(20) 외부로 돌출된 플런저 팁(50)으로 분해 장치를 이동시키게 된다.In order to replace the plunger tip 50 due to abrasion of the plunger tip 50 which pushes the molten metal filled in the sleeve 10 into the mold 20 while reciprocating the inside of the sleeve 10 of the high pressure casting machine. After advancing the tip 50 to protrude to the outside of the mold 20, and fixing the engaging portion 120 of the bearing 110 installed on the outer surface of the shaft 100 by using the crane 130, the worker is the mold (20) The disassembly device is moved to the plunger tip 50 which protrudes outward.

이렇게, 이동된 플런저 팁 분해장치의 클램프(300) 집개부(310)의 선단부를 플런저 팁(50) 후단부에 건 후에 작업자는 제1링크(320)를 내측으로 잡아당기게 되면 제2링크(330)와 제3링크(340)전방 내측 방향으로 회동되어 지고, 집게부(310)는 플런저 팁(50)을 몸체(200)의 전방면으로 밀착시켜 잡아당기게 되어 플런저 팁(50)을 고정시키게 된다.In this manner, after the front end of the clamp 310 of the moved plunger tip disassembly device is attached to the rear end of the plunger tip 50, when the operator pulls the first link 320 inward, the second link 330 ) And the third link 340 is rotated in the front inward direction, the tong portion 310 is pulled by pulling the plunger tip 50 in close contact with the front surface of the body 200 to fix the plunger tip (50). .

이 후, 작업자는 샤프트(100) 후단부에 회전수단인 토오크 랜치(400)를 연결 설치하여 샤프트(100)를 회전시키면 이 샤프트(100)의 회전에 따라 몸체(200)가 회전되고, 이 몸체(200)에 연결설치되어 플런저 팁(50)을 물고 있는 클램프(300)가 회전되어 플런저 로드(51)에 설치되어 있던 플런저 팁(50)을 회전시켜 분리하게 된다.Thereafter, the operator connects and installs the torque wrench 400 which is a rotation means at the rear end of the shaft 100 to rotate the shaft 100. The body 200 is rotated according to the rotation of the shaft 100. The clamp 300, which is connected to the 200 and bites the plunger tip 50, is rotated and separated by rotating the plunger tip 50 installed in the plunger rod 51.

상기 플런저 팁(50) 분해 후에도 플런저 팁(50)은 클램프(300)의 집개부(310)에 물려 있으므로 원하는 장소까지 크래인(130)을 이용하여 이동시킨 후 분리하게 된다.Even after disassembling the plunger tip 50, the plunger tip 50 is bitten by the clamping part 310 of the clamp 300, and then separated by using the crane 130 to a desired place.

상술한 바와 같이 본 발명에 따른 고압주조기 플런저 팁 분해 장치에 따르면, 작업자의 수작업이 아닌 플런저 팁 분해장치의 클램프를 이용해 중량물인 플런저 팁을 분해하기 때문에 작업방법이 안전하여 안전사고를 미연에 방지할 수 있는 효과와, 반대로 조립시에도 플런저 팁을 클램프에 고정하여 플런저 로드에 조립시에도 작업자의 플런저 팁 회전을 통한 수작업을 대체하여 작업시간의 단축 및 안전사고 발생에 따른 산업재해를 예방할 수 있는 효과가 있다.As described above, according to the high-pressure casting machine plunger tip disassembly apparatus according to the present invention, since the heavy plunger tip is disassembled using the clamp of the plunger tip disassembly apparatus instead of the operator's manual work, the work method is safe and prevents safety accidents. On the contrary, the plunger tip is fixed to the clamp when assembling to replace the manual work by rotating the plunger tip of the operator even when assembling on the plunger rod, thereby reducing the working time and preventing industrial accidents caused by safety accidents. There is.
