Description
본 발명은 다이캐스팅 작업시 성형물과 금형의 분리를 용이하게 하기위하여 금형에 도포하는 이형제(離型劑)를 압축공기를 이용하여 분사하는 이형제 분사장치에 관한 것으로, 분사후 유출된 잉여 이형제를 회수하여 폐유를 분리하고 여과하는 정제과정을 거쳐 재사용이 가능하도록 함으로써 이형제의 낭비와 이형제 및 폐유의 방류로 인한 환경오염을 방지하고, 금형에 분사되어 소모된 이형제와 분사, 회수 및 정제과정 중 증발 등으로 인한 자연손실분을 자동으로 보충하도록 하여 작업의 편리함과 효율성을 증대한 것이다.The present invention relates to a releasing agent injector for spraying a mold release agent (離 型 劑) applied to the mold using compressed air in order to facilitate the separation of the molding and the mold during the die casting operation, to recover the excess release agent discharged after injection By reusing waste oil after refining process to separate and filter waste oil, it prevents waste of mold release agent and environmental pollution caused by release of mold release agent and waste oil. The natural loss caused by the automatic replenishment to increase the convenience and efficiency of work.
다이캐스팅(DIE CASTING)은 금형에 용융된 금속을 주입하여 성형하는 것으로 조직이 치밀하고 정밀도가 높을 성형물을 얻을 수 있는 주조법의 일종이다.Die casting (DIE CASTING) is a type of casting method in which a molten metal is injected into a mold and molded to obtain a molded product having a dense structure and high precision.
이러한 다이캐스팅에 있어서 금형은 성형물을 떼어낸후 반복 사용되는 주형으로서, 성형물과 금형의 원활한 분리가 이루어지지 않을 경우 성형물의 불량이 발생할 뿐 아니라 고가의 장비인 금형자체도 손상되는 심각한 결과를 초래하게 되므로, 미리 금형 표면에 이형제(離型劑; PARTING AGENT)를 도포하여 성형물과 금형이 원활하게 분리되도록 한다.In this die casting, the mold is a mold that is repeatedly used after removing the molding, and if the molding and the mold are not separated smoothly, the mold is not only defective but also causes a serious result of damaging the expensive mold itself. A mold release agent (PARTING AGENT) is applied to the mold surface in advance so that the molding and the mold can be separated smoothly.
일반적으로 이형제는 금속이나 수지상(樹脂狀)의 윤활물질을 에멀션화(EMULSIFICATION)한 원액을 물에 일정비율로 희석하여 사용하게 되며, 금형 표면에 스프레이어 등을 이용하여 고르게 분사, 도포하여 사용한다.Generally, the release agent is used by diluting a stock solution obtained by emulsifying a metal or resinous lubricating substance to a certain ratio in water, and spraying and applying it evenly using a sprayer on the mold surface. .
분사된 이형제의 일부는 금형에 도포되어 피막을 형성하게 되고, 일부는 다이캐스팅기계를 타고 유출되게 되는데, 이때 유출된 이형제는 다이캐스팅기계 표면의 먼지나 윤활유와 같은 각종 이물질이 혼합되어 재사용이 불가능한 상태가 되므로 전량 폐기되는 실정이다.A part of the sprayed release agent is applied to a mold to form a film, and a part is discharged through a die casting machine. At this time, the spilled release agent is mixed with various foreign substances such as dust or lubricant on the surface of the die casting machine, making it impossible to reuse. Therefore, the entire situation is discarded.
따라서, 분사되는 이형제 전량이 소모되어 이형제가 낭비될 뿐 아니라, 유출된 이형제가 하수구나 토양으로 스며들어 수질 및 토양오염 등의 심각한 문제를 야기하며, 이형제 분사기에 계속하여 소모분을 보충해줘야 하는 번거로움이 있었다.Therefore, not only the amount of release agent injected is consumed, and the release agent is wasted, and the leaked release agent penetrates into the sewer or soil, causing serious problems such as water quality and soil contamination, and the hassle of continuously replenishing the consumption of the release agent injector. There was a feeling.
특히, 유출된 폐이형제는 별도의 처리시설에서 정화처리후 방류하거나 전문처리업체에 의뢰하여 처리하여야 하지만 이를 위하여는 막대한 비용이 소요되므로 대다수의 소규모 다이캐스팅 업체에서는 폐이형제를 그대로 방류하는 실정이다.In particular, the spilled waste release agent must be discharged after purification treatment in a separate treatment facility or requested by a specialized treatment company, but this requires a huge cost, so many small die casting companies discharge the waste release agent as it is.
본 발명은 전술한 문제점을 감안하여 창안한 것으로, 금형에 분사된 후 다이캐스팅기계를 타고 유출된 잉여 이형제를 회수하여 다이캐스팅기계로부터 유입된 폐유를 흡착하여 분리한 후 여과함으로써 재사용이 가능하도록 하였으며, 소모된 이형제는 각종 센서를 통해 감지하여 자동으로 보충하도록 하였고, 이형제 원액을 희석함에 있어서도 혼합실린더, 전동밸브 및 액위센서를 이용하여 정확한 혼합비로 자동 희석되도록 하였다.The present invention was devised in view of the above-described problems, and after the injection into the mold, the excess release agent leaked out by the die casting machine was recovered, and the waste oil introduced from the die casting machine was adsorbed, separated, filtered, and reused. The release agent was sensed through various sensors to automatically replenish the diluent, and even when diluting the release agent stock solution, the diluent was automatically diluted with the correct mixing ratio by using a mixing cylinder, an electric valve, and a liquid level sensor.

본 발명의 상세한 구조를 첨부된 도면을 이용하여 설명하면 다음과 같다.The detailed structure of the present invention will be described with reference to the accompanying drawings.
도 1은 본 발명의 전체적인 구성을 나타낸 것으로서, 이형제를 분사하기 위한 압력용기(700)와 이형제 원액을 저장하는 이형제저장조(300), 이형제를 희석하는 희석조(400), 이형제저장조(300)로부터 일정량의 이형제 원액을 흡입하여 이를 희석조(400)에 주입하는 혼합실린더(200), 다이캐스팅기계(900)에 분사된후 회수된 이형제에서 폐유(910)를 분리하여 정제하는 폐유분리조(100) 및 이들 구성요소들을 연결하고 구동하며 제어하는 각종 배관, 펌프, 모터, 센서 등이 도시되어 있다.Figure 1 shows the overall configuration of the present invention, a pressure vessel 700 for spraying the release agent and a release agent storage tank 300 for storing the release agent stock solution, a dilution tank 400 for diluting the release agent, from the release agent storage tank 300 Waste oil separation tank 100 for separating and purifying waste oil 910 from the release agent recovered after the injection to the mixing cylinder 200, the die casting machine 900 to suck a predetermined amount of the release agent stock solution to the dilution tank 400 And various piping, pumps, motors, sensors and the like for connecting, driving and controlling these components.
본 발명의 작동원리는 도 8에서와 같이, 압력용기(700)에 채워진 이형제가 압축공기공급관(730)으로 공급된 압축공기의 압력에 의하여 이형제분사관(720)을 통하여 다이캐스팅기계(900)에 분사되고, 분사된 이형제 중 다이캐스팅기계(900)를 타고 유출된 잉여이형제가 회수조(500)로 유입되며, 유입된 이형제는 회수펌프(160)에 의하여 폐유분리조(100)에 내장된 분출부(130)로 압송되게 된다.The operating principle of the present invention, as shown in Figure 8, the release agent filled in the pressure vessel 700 by the pressure of the compressed air supplied to the compressed air supply pipe 730 to the die casting machine 900 through the release agent injection pipe (720) Among the sprayed and released mold release agents, the excess release agent discharged through the die casting machine 900 flows into the recovery tank 500, and the introduced release agent is a blowing unit built in the waste oil separation tank 100 by the recovery pump 160. To be pushed to 130.
회수조(500)는 통상적으로 다이캐스팅기계(900)의 하부를 굴착하여 설치하게 되며, 회수조(500) 상부에 지지 부재 등을 설치하고 그 위에 다이캐스팅기계(900)를 거치하게 된다.Recovery tank 500 is typically installed by excavating the lower portion of the die-casting machine 900, the support member is installed on the recovery tank 500, and the die-casting machine 900 is mounted thereon.
도 5에서와 같은 구조의 분출부(130)로 압송된 잉여이형제는 외부배관연결부(134)를 통하여 분출통(132) 내로 유입되게 되며, 분출공(133)을 통하여 분출된후 외통(131) 내측을 타고 유출되게 된다.The excess release agent pumped into the jetting unit 130 having the structure as shown in FIG. 5 is introduced into the jetting tube 132 through the external pipe connection part 134, and is discharged through the jetting hole 133 and then the outer cylinder 131. It will flow out on the inside.
분출부(130)를 통하여 폐유분리조(100)로 유입된 잉여이형제는 순수한 이형제가 아니라 다이캐스팅기계(900)로부터 유출되고 회수조(500)로 회수되는 과정에서 각종 폐유(910) 및 불순물이 혼합된 혼합물 이므로, 이들 폐유(910) 및 불순물을 분리하는 정제과정이 필요하며, 폐유분리조(100)통하여 이러한 정제과정을 수행하게 된다.The excess release agent introduced into the waste oil separation tank 100 through the ejection unit 130 is not a pure release agent but mixed with various waste oils 910 and impurities in the process of being discharged from the die casting machine 900 and recovered to the recovery tank 500. Since it is a mixture, a purification process for separating these waste oils (910) and impurities is required, and this purification process is performed through the waste oil separation tank (100).
폐유분리조(100)는 도 2 내지 3에서와 같이, 내부에 다수의 격벽이 형성되고, 상부에는 흡착로울러(110), 이송날개(120) 및 토출구(101)가 구비된 직육면체 형태의 용기로서, 유입된 잉여이형제가 격벽에 의하여 최대한 정온성(靜穩性) 유지하도록 하여 비중이 낮은 폐유(910)가 상승하도록 하고, 상승하여 상부에 층을 이룬 폐유(910)는 흡착로울러(110)로 흡착한후, 압밀봉(111)으로 압착, 이탈시켜 토출구(101)로 배출되도록 한 것이다.Waste oil separation tank 100, as shown in Figures 2 to 3, a plurality of partitions are formed therein, the upper portion as a rectangular parallelepiped container provided with a suction roller 110, the transfer blade 120 and the discharge port 101. The waste oil 910 having a low specific gravity is raised by increasing the surplus release agent to be kept at a constant temperature by the partition wall, and the waste oil 910 which is layered on the upper portion is raised to the adsorption roller 110. After the adsorption, it is compressed and separated by the consolidation rod 111 to be discharged to the discharge port 101.
이러한 폐유분리조(100)의 내부공간은 도 3에서와 같이, 경사지게 설치된 상하분리판(141)과, 하단은 폐유분리조(100) 내측 하부면에 접하고 상단은 상하분리판(141)의 하부면과 소정 거리 이격된 상태로 설치된 다수의 하부격벽(144) 및 하단이 상하분리판(141)의 상부면에 접하도록 설치된 다수의 상부격벽(142)으로 분할되며, 상부격벽(142) 및 하부격벽(144)의 하단에는 각각 상부통로(143) 및 하부통로(145)가 좌, 우측에 교대로 형성되어 격벽 사이의 공간을 연결하게 된다.As shown in Figure 3, the inner space of the waste oil separation tank 100, the upper and lower separation plate 141 is installed obliquely, the lower end is in contact with the inner bottom surface of the waste oil separation tank 100, the upper end of the upper and lower separation plate 141 The plurality of lower partitions 144 and the lower end spaced apart from the surface by a predetermined distance are divided into a plurality of upper partitions 142 installed to contact the upper surface of the upper and lower separator 141, the upper partition 142 and the lower An upper passage 143 and a lower passage 145 are alternately formed at the left and right sides of the partition 144 to connect spaces between the partition walls.
또한, 상기 상하분리판(141)은 상측 및 하측단이 폐유분리조(100)의 내측면과 소정 거리 이격되도록 설치하여, 상하분리판(141)의 상, 하부 공간이 연결될 수 있도록 하고, 전술한 분출부(130)를 상하분리판(141) 상측단의 상부에 설치하여 분출부(130)를 통하여 유입된 잉여이형제가 상하분리판(141)의 상부면을 따르는유로(流路)를 형성하며 흘러서 폐유분리조(100)를 채우도록 하였다.In addition, the upper and lower separation plates 141 are installed so that the upper and lower ends are spaced apart from the inner surface of the waste oil separation tank 100 by a predetermined distance, so that the upper and lower spaces of the upper and lower separation plates 141 can be connected to each other. One ejection part 130 is installed on the upper end of the upper and lower separator plates 141 to form a flow path along the upper surface of the upper and lower separator plates 141 with excess release agent introduced through the ejection part 130. And flow to fill the waste oil separation tank (100).
이렇듯 내부 공간이 분할된 폐유분리조(100)의 구조로 인하여 폐유분리조(100)에 잉여이형제가 채워지는 과정에 있어서 분출부(130)의 분출작용으로 인한 교란이 최소화 되고, 폐유분리조(100)내에서의 이형제 흐름에 있어서도 상부통로(143) 및 하부통로(145)를 따라 사행(蛇行)유로를 형성하게 되므로, 높은 정온성(靜穩性)을 유지할 수 있게 되어 비중차에 의한 이형제와 폐유(910)의 분리가 원활히 이루어지게 된다.As such, due to the structure of the waste oil separation tank 100 in which the internal space is divided, disturbance due to the ejection action of the ejection unit 130 is minimized in the process of filling the excess mold release agent in the waste oil separation tank 100, and the waste oil separation tank ( In the flow of the releasing agent in 100, the meandering flow path is formed along the upper passage 143 and the lower passage 145, so that it is possible to maintain a high temperature stability and release agent due to specific gravity difference. And the separation of the waste oil 910 is made smoothly.
특히, 상하분리판(141) 상부 공간에서 미처 분리되지 못한 폐유(910)는 도 8에서와 같이 하부 공간에서 분리되어 상하분리판(141) 하부 경사면을 따라 상승하여, 결국 폐유분리조(100) 상부에 형성된 폐유(910)층에 합류하게 된다.In particular, the waste oil 910 not separated in the upper space of the upper and lower separation plates 141 is separated in the lower space as shown in FIG. 8 and rises along the lower slope of the upper and lower separation plates 141, resulting in the waste oil separation tank 100. Join the waste oil (910) layer formed on the top.
폐유분리조(100)의 상부격벽(142) 및 분출부(130) 상부에는 서로 평행한 축을 가지는 흡착로울러(110) 및 이송날개(120)가 체인(121)으로 연결되어 로울러구동모터(114)에 의하여 회전되도록 설치된다.A suction roller 110 and a transfer blade 120 having axes parallel to each other are connected to the chain 121 at the upper partition 142 and the ejection portion 130 of the waste oil separation tank 100 by a roller driving motor 114. It is installed to rotate by.
이송날개(120)가 회전함에 따라 폐유분리조(100) 상부에 층을 이룬 폐유(910)가 흡착로울러(110) 쪽으로 이송되게 되며, 이송된 폐유(910)는 흡착로울러(110)에 흡착된후, 흡착로울러(110)에 밀착되도록 설치된 압밀봉(111)에 의하여 압착, 이탈되어 토출구(101)로 배출되게 된다.As the transfer blade 120 rotates, the waste oil 910 layered on the waste oil separation tank 100 is transferred toward the adsorption roller 110, and the transferred waste oil 910 is adsorbed by the adsorption roller 110. Thereafter, by the pressing rod 111 installed to be in close contact with the adsorption roller 110, it is compressed and released to be discharged to the discharge port (101).
흡착로울러(110)의 표면은 스폰지와 같이 흡착력이 우수한 소재로 이루어지며, 압밀봉(111)에는 도 1 내지 2에서와 같이 스프링(112)과 조절핸들(113)이 연결되어 압밀봉(111)이 흡착로울러(110)를 누르는 힘을 조절할 수 있도록 하였다.The surface of the adsorption roller 110 is made of a material having excellent adsorption power, such as a sponge, the consolidation rod 111 is connected to the spring 112 and the control handle 113 as shown in Figure 1 to 2 consolidation rod 111 The adsorption roller 110 was able to adjust the pressing force.
전술한 과정에 의하여 폐유(910)가 분리된 이형제는 폐유분리조(100) 하부에 설치된 분리조필터(150)를 통과하면서 분순물이 여과되며, 이렇듯 폐유(910)와 불순물이 제거된 이형제는 고압펌프(600)에 의하여 압송되어 이형제공급관(710)을 통해 압력용기(700)에 주입된다.The release agent from which the waste oil 910 is separated by the above-described process is filtered through the separation tank filter 150 installed at the bottom of the waste oil separation tank 100. Thus, the release agent from which the waste oil 910 and impurities are removed is removed.
