본 발명은 에어가 적용되는 다이 캐스팅 금형에 관한 것으로서, 특히 다이캐스팅 금형의 제품인출후 이물질제거용 필터에 필터링되는 이물질을 매공정마다 깨끗하게 제거할수 있도록 한 다이캐스팅의 이물질제거장치에 관한 것이다.The present invention relates to a die casting mold to which air is applied, and more particularly, to a foreign substance removing apparatus of a die casting to remove the foreign substances filtered by the foreign substance removing filter after the product of the die casting mold is removed at every step.

일반적으로 다이캐스팅금형은 제품형상이 가공된 한쌍의 금형편의 결합면을 일치시킨후 일측의 용탕주입구를 통하여 상측과 연결된 진공탱크의 진공흡입력에 의해 용탕을 주입시켜 제품을 양산토록하는 것은 주지된 사실이다.In general, it is well known that die casting molds produce mass products by injecting molten metal by the vacuum suction input of a vacuum tank connected to the upper side through the molten metal inlet and matching the mating surfaces of a pair of mold pieces processed into product shapes. .

그러나 종래의 다이캐스팅금형(51)은 제3도에서와 같이 제품모양이 가공된 한쌍의 금형편(52)(52^)을 설치하되 일측의 금형편(52)에는 용탕이 주입될 수 있는 용탕주입구(53)가 형성되고, 금형편(52)(52^)의 결합면 상측의 진공넌너(54)끝단에는 칠블럭(Chill Block)(55)를 설치하였다.However, in the conventional die casting mold 51, as shown in FIG. 3, a pair of mold pieces 52 and 52 ^ having a product shape are installed, but a molten metal inlet for injection of molten metal into one side of the mold piece 52 is provided. A 53 was formed, and a chill block 55 was provided at the end of the vacuum column 54 above the joining surface of the mold pieces 52, 52 ^.

그리고 상기 칠블럭(55)은 파이프(57)를 연결하여 진공탱크(56)와 연결하였다.The chill block 55 is connected to the vacuum tank 56 by connecting the pipe 57.

이때 상기 파이프(57)내부에는 진공흡입시 금형편(52)(52^)내부의 이물질이 진공탱크(56)로 유입되지 못하도록 이물질제거용필터(58)를 장착설치하여 구성된 것이다.At this time, the inside of the pipe 57 is installed by installing a foreign matter removal filter 58 so that foreign matter inside the mold pieces 52, 52 ^ does not flow into the vacuum tank 56 during vacuum suction.

이와같이, 구성된 종래의 다이캐스팅금형(51)은 제품형성시 한쌍의 금형편(52)(52^)의 결합면을 밀착되게 조립한 후 작동하면 금형편(52)(52^)내부가 진공상태로 되면서 용탕주입구(53)로 용탕주입구(53)로 용탕이 유입하여 제품을 형성한다.In this way, the conventional die casting mold 51 configured as described above closely assembles the mating surfaces of the pair of mold pieces 52, 52 ^ in forming the product, and then operates the mold pieces 52, 52 ^ in a vacuum state. While the molten metal flows into the molten metal inlet 53 into the molten metal inlet 53 to form a product.

이때, 상기 제품형성시 진공탱크(56)의 작동으로 금형편(52)(52^)내부를 진공상태로 만들 때 금형편(52)(52^)내부의 이물질은 파이프(57)내부에 설치된 이물질제거용필터(58)에 필터링되게 된다.At this time, the foreign matter inside the mold pieces 52 and 52 ^ is formed inside the pipe 57 when the inside of the mold pieces 52 and 52 ^ is vacuumed by the operation of the vacuum tank 56 at the time of forming the product. The foreign matter removal filter 58 is filtered.

그러나 초기의 금형 사출시에는 이물질제거로 깨끗한 제품을 양산할 수 있지만, 장기간 사용할 때에는 수시로 이물질제거용필터(58)를 분리하여 청소작업을 하여야하는 번거러운 결점등이 야기되었을 뿐만 아니라 청소불량시에는 이물질제거용필터(58)에 의해 필터링된 이물질이 떨어져 금형편(52)(52^)내부로 유입되어 제품을 양산함에 따라 깨끗한 제품을 얻지 못하게 되는 문제점등이 야기되었다.However, in the initial mold injection, clean products can be mass-produced by removing debris, but in the case of long-term use, the cumbersome defects such as removing the debris removal filter 58 from time to time and cleaning work are caused. The foreign matter filtered by the removal filter 58 falls into the mold pieces 52 and 52 ^, and as a result, mass production of the product causes problems such as the inability to obtain a clean product.

본 발명은 상기한 종래의 제 결점 및 문제점 등을 감안하여 된것으로서, 본 발명의 그주된 목적으론 파이프에 설치되어 이물질을 제거하는 이물질제거용필터와 이격된 지점에 진공탱크 온.오프용 진공솔레노이드밸브를 설치한후, 이물질제거용 필터와 진공솔레노이드밸브 사이에 에어탱크 온.오프용 에어솔레노이드 밸브를 설치하여 금형의 제품인출로 인해 금형편이 벌어질 때, 에어펌프가 작동하여 이물질제거용필터에 달라붙었던 이물질을 매작동시마다 제거할 수 있도록 하여, 이물질제거용필터에 장기간 사용할 뿐만 아니라 제품사출시 이물질의 침투가 전혀없게 되어 깨끗한 제품을 생산할 수 있도록 한 것이 그 목적이다.The present invention has been made in view of the above-mentioned conventional drawbacks and problems, and the main purpose of the present invention is to provide a vacuum solenoid for vacuum tank on / off at a point separated from a filter for removing foreign substances which is installed in a pipe to remove foreign substances. After installing the valve, install an air tank on / off air solenoid valve between the filter for removing foreign substances and the vacuum solenoid valve, and when the mold piece is opened due to the product drawing out of the mold, the air pump operates to The purpose of this is to make it possible to remove the foreign matter stuck at every operation, so that it can be used for a long time in the filter for removing the foreign matter and there is no penetration of foreign matter at the time of product injection, so that a clean product can be produced.

상기의 목적을 달성할 수 있는 본 발명을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.When described in detail by the accompanying drawings, the present invention that can achieve the above object is as follows.

제1도는 본 발명이 적용된 금형의 개략측면도이고1 is a schematic side view of a mold to which the present invention is applied.

제2도는 본 발명의 요부단면도이다.2 is a cross-sectional view of main parts of the present invention.

제1도 및 제2도에서와 같이 다이캐스팅금형(51)은 내부에 제품형상이 가공된 한쌍의 금형편(2)(2^)의 결합면이 밀착되게 조립한다.As shown in FIG. 1 and FIG. 2, the die casting mold 51 is assembled so that the mating surfaces of the pair of mold pieces 2 (2 ^) in which the product shape is processed are in close contact.

그리고 상기 금형편(2)의 하측으론 용탕을 주입할 수 있는 용탕주입구(3)를 형성하였고, 상측에는 진공넌너(4)가 형성되었다.A molten metal injection hole 3 through which the molten metal can be injected is formed below the mold piece 2, and a vacuum thinner 4 is formed on the upper side thereof.

그리고 상기 진공넌너(4)상측으론 진공의 잔여분을 밀어낼 수 있도록 칠블럭(5)을 장착설치하고 이 칠블럭(5)은 파이프(7)로 연결하여 진공탱크(6)와 연결하였다.The chill block 5 is installed to push the residual portion of the vacuum above the vacuum nender 4, and the chill block 5 is connected to the vacuum tank 6 by a pipe 7.

한편, 상기 파이프(7)에는 진공시 흡입된 이물질을 필터링할 수 있는 이물질제거용필터(8)를 장착하고, 이물질제거용필터(8)로부터 일정거리 떨어진 지점에는 진공탱크(6) 온.오프용 진공솔레노이드밸브(9)를 설치하고, 상기 이물질제거용필터(8)와 진공솔레노이드밸브(9)간에는 에어탱크(10)와 에어라인(11)으로 연결하되, 에어라인(11) 통로에는 에어탱크(10) 온.오프용 에어솔레노이드밸브(12)를 설치하여 구성한 것이다.On the other hand, the pipe (7) is equipped with a foreign matter removal filter (8) for filtering the foreign matter sucked in the vacuum, and the vacuum tank (6) on and off at a point away from the foreign matter removal filter (8). A vacuum solenoid valve 9 is installed, and the foreign matter removing filter 8 and the vacuum solenoid valve 9 are connected to the air tank 10 and the air line 11, but the air line 11 is connected to the air. The tank 10 is configured by installing an air solenoid valve 12 for on and off.

이와같이 구성된 본 발명의 다이캐스팅금형(1)은 제품형상이 가공된 금형편(2)(2^)의 결합면을 밀착시킨후 제품을 성형코자할시 진공탱크(6)가 연결된 에어라인(11)의 에어솔레노이드밸브(12)가 오프상태에서 작동하여 한쌍의 금형편(2)(2^)의내부의 진공을 파이프(7)를 통하여 빨아들이면, 빨아들인 진공만큼 용탕을 용탕주입구(3)로 빨아들인다.The die casting mold 1 of the present invention configured as described above has an air line 11 connected to a vacuum tank 6 when forming a product after closely contacting a joining surface of a mold piece 2 (2 ^) in which a product shape is processed. Air solenoid valve 12 is operated in the off state to suck the vacuum inside the pair of mold pieces 2, 2 ^ through the pipe 7, and the molten vacuum is transferred to the molten metal inlet 3 as much as the sucked vacuum. Suck

이때, 상기 진공펌프(6)의 작동에 의해 금형편(2)(2^)내부의 진공시 금형편(2)(2^)내부에 있던 이물질은 파이프(7)에 설치된 이물질제거용필터(8)에 필터링되게되고, 용탕주입구(3)를 통하여 들어온 용탕은 진공을 밀어내면서 진공넌너(4)와 칠블럭(5)까지 유입되어 제품이 매끄럽게 되는 것이다.At this time, by the operation of the vacuum pump 6, the foreign matter in the mold piece (2) (2 ^) during the vacuum in the mold piece (2) (2 ^) is a foreign material removal filter installed in the pipe ( 8) to be filtered, and the molten metal introduced through the molten metal inlet 3 flows into the vacuum nender 4 and the chill block 5 while pushing the vacuum to smooth the product.

그리고 금형편(2)(2^)내부에서 제품형성이 완료되어 제품을 인출후에는 진공탱크(6)는 작동을 멈춘상태에서 진공솔레노이드밸브(9)가 오프되고 에어펌프(10)가 작동되면서 에어솔레노이드밸브(12)를 온시켜 에어라인(11)을 통하여 강한 에어를 공급한다.After the product formation is completed in the mold piece 2 (2 ^) and the product is withdrawn, the vacuum solenoid valve 9 is turned off and the air pump 10 is operated while the vacuum tank 6 is stopped. The air solenoid valve 12 is turned on to supply strong air through the air line 11.

그러면 공급된 에어펌프(10)의 에어는 이물질제거용필터(8)를 통해 빠져 나간다.Then, the air of the supplied air pump 10 exits through the foreign matter removing filter 8.

이때, 에어가 빠져나가는 과정에서 이물질제거시의 역방향으로 1회 진공시마다 이물질을 제거하게되어 이물질제거용필터가 항시 깨끗하게 유지되는 것이다.At this time, the foreign material is removed every vacuum in the reverse direction when removing the foreign matter in the process of air escape is to keep the foreign matter removal filter is always clean.
