It is about.
주지된 바와 같이, 금속을 용해시켜 소정의 금속부재로 제조하기 위하여 다이케스팅 압출제조기가 사용되어지는데, 상기 다이케스팅 압출제조기는 크게 나누어 금속을 소정의 온도에서 용해시키는 용해로장치와, 용해로장치에서 용해된 금속용해물을 주사하는 노즐장치와, 노즐장치로부터 주사된 금속용해물을 금형에 주입하여 소정의 형상으로 제조하는 금형장치 등으로 구성된다.As is well known, a die casting extruder is used to melt a metal into a predetermined metal member, and the die casting extruder is divided into a melting apparatus for dissolving the metal at a predetermined temperature and a metal melted in the melting apparatus. And a nozzle apparatus for scanning the melt, and a mold apparatus for injecting the metal melt injected from the nozzle apparatus into a mold to produce a predetermined shape.
여기에서, 본 발명과 관련된 노즐장치에 대해서 좀 더 상세히 설명하면, 도 1과 같이 축방향으로 소정 직경의 노즐공(1a)이 형성된 금속재질의 노즐부(1)가 설치되고, 상기 노즐부(1)의 직하부에 노즐공(1a)을 따라 흐르는 금속용해물의 냉각을 방지할 수 있도록 다수의 화염분사기(2)가 설치된다.Herein, a nozzle apparatus related to the present invention will be described in more detail. As shown in FIG. 1, a nozzle unit 1 made of metal having a nozzle hole 1a having a predetermined diameter in the axial direction is provided, and the nozzle unit ( A plurality of flame sprayers 2 are installed directly below 1) to prevent cooling of the metal melt flowing along the nozzle hole 1a.
즉, 용해로장치로부터 노즐공(1a)으로 공급된 금속용해물은 용해온도 이하로 급속히 낮아져 응고되는데, 이때 화염분사기(2)를 이용하여 노즐부(1)를 금속의 용해온도, 또는 그 이상으로 일정하게 가열하므로서 다이케스팅작업을 연속적으로 수행할 수 있게 된다.That is, the metal lysate supplied from the melting furnace apparatus to the nozzle hole 1a is rapidly lowered to below the melting temperature and solidified. At this time, the flame sprayer 2 is used to move the nozzle unit 1 to the melting temperature of the metal or higher. By constant heating, die casting can be carried out continuously.
그런데, 상기와 같이 종래에는 노즐부(1)를 다수의 화염분사기(2)를 이용하여 가열하기 때문에 화력의 세기를 정밀하게 조절할 수 없어 노즐의 온도분포와 가열온도를 일정하게 유지시키기가 극히 어려울 뿐만 아니라, 이로 인하여 양질의 제품을 생산하기가 매우 어렵다는 문제점이 있었다.However, as described above, since the nozzle unit 1 is heated by using a plurality of flame sprayers 2, it is difficult to precisely control the intensity of the thermal power, and thus it is extremely difficult to keep the temperature distribution and the heating temperature of the nozzle constant. In addition, there was a problem that it is very difficult to produce a quality product.
따라서, 본 발명은 상기와 같은 문제점을 감암하여 창안한 것으로서, 노즐부의 외주부에 고주파발진수단을 설치. 고주파를 발진시키므로서 노즐공을 따라 흐르는 금속용해물을 일정한 온도로 유지시켜 작업효율 및 생산성을 크게 향상시킴은 물론이고, 노즐부의 가열시간과 온도분위기를 정밀하게 제어함은 물론이고 고주파발진수단에 의한 노즐부의 가열속도를 크게 단축시킬 수 있어 양질의 제품을 다량으로 생산할 수 있으며, 또한 화염을 발생시킬 때 발생되는 오염을 완전히 방지할 수 있으므로 쾌적한 작업환경을 유지할 수 있는 다이케스팅 압출제조기의 노즐장치를 제공함에 그 목적이 있다.Therefore, the present invention was conceived to overcome the above problems, and the high frequency oscillation means is provided in the outer peripheral part of the nozzle unit. By oscillating the high frequency, the metal melt flowing along the nozzle hole is maintained at a constant temperature, which greatly improves work efficiency and productivity, and precisely controls the heating time and temperature atmosphere of the nozzle unit. It can reduce the heating speed of the nozzle part by a large amount, and can produce a large amount of high quality products. Also, it can completely prevent the pollution generated when generating a flame, so that the nozzle device of the die casting extrusion manufacturing machine can maintain a comfortable working environment.

본 발명은 상기와 같은 목적을 달성하기 위하여 금속을 소정의 온도에서 용해시키는 용해로장치와, 용해로장치에서 용해된 금속용해물을 주사하는 노즐장치와, 노즐장치로부터 주사된 금속용해물을 금형에 주입하여 소정의 형상으로 제조하는 금형장치 등으로 구성된 다이케스팅 압출제조기에 있어서, 중심축선상을 따라 노즐공이 형성된 노즐부의 외주부에 고주파코일이 일정하게 배치된 고주파발진수단을 설치하는 한편, 상기 고주파코일의 외주부에 단열부재를 설치한 것을 특징으로 한다.In order to achieve the above object, the present invention provides a melting furnace apparatus for dissolving a metal at a predetermined temperature, a nozzle apparatus for injecting the dissolved metal dissolved in the melting apparatus, and a metal melt injected from the nozzle apparatus into the mold.

There is a characteristic.
이하, 본 발명의 바람직한 일실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 따른 노즐장치의 노즐부를 발췌도시한 단면도이고, 도 3은 본 발명에 따른 다이케스팅 압출제조기의 노즐장치를 발췌도시한 구성도이다.Figure 2 is a cross-sectional view showing an extract of the nozzle unit of the nozzle apparatus according to the present invention, Figure 3 is a block diagram showing an extractor of the nozzle apparatus of the die casting extrusion machine according to the present invention.
노즐장치는 크게 나누어 관형상의 노즐부(10)와. 상기 노즐부(10)를 소정의 온도로 가열시키는 고주파발진수단(20)과, 상기 노즐부(10)의 열이 외부로 방출되는 것을 방지하는 단열부재(30)로 구성된다.The nozzle device is largely divided into a tubular nozzle part 10 and the tubular nozzle part 10. High frequency oscillation means 20 for heating the nozzle unit 10 to a predetermined temperature, and the heat insulating member 30 for preventing the heat of the nozzle unit 10 to be discharged to the outside.
먼저, 노즐부(10)는 열전도가 탁월하면서 강자성체인 금속재질로 형성되며, 상기 노즐부(10)의 중심축선상을 따라 소정 직경의 노즐공(11)이 형성되는데, 상기 노즐공(11)은 금속용해물의 압출용량에 따라 그 직경이 달라지며, 상기 노즐부(10)의 인입구 주변과 중간부분에 노즐부(10)의 각 부분의 온도를 감지하는 온도감지센서(12)가 설치된다.First, the nozzle unit 10 is formed of a metal material which is excellent in thermal conductivity and ferromagnetic material, and a nozzle hole 11 having a predetermined diameter is formed along the central axis of the nozzle unit 10. The diameter varies according to the extrusion capacity of the silver metal lysate, and a temperature sensor 12 is installed at the periphery and the middle of the nozzle part 10 to sense the temperature of each part of the nozzle part 10. .
그리고, 고주파발진수단(20)은 노즐부(10)의 외주부에 고주파전류가 흐르는 동파이프로 된 고주파코일(21)이 설치되는데, 상기 고주파코일(21)은 전방가열용 코일(21a)과 후방가열용 코일(21b)로 구획 설치되어 노즐부(10)에 설치된 온도감지센서(12)의 감지된 온도에 따라 노즐부(10)의 전방과 후방, 또는 전체를 선택적으로 유도가열하게 된다.In addition, the high frequency oscillation means 20 is provided with a high frequency coil 21 made of copper pipe through which a high frequency current flows on the outer circumference of the nozzle unit 10. The high frequency coil 21 has a front heating coil 21a and a rear side. Partitioned with a heating coil (21b) is to selectively induction heating the front and rear, or the whole of the nozzle unit 10 in accordance with the detected temperature of the temperature sensor 12 installed in the nozzle unit (10).
이때, 유도가열이란 고주파전류가 흐르는 코일속에 위치한 금속 등의 도전체는 와전류 손실과 히스테리시스(hysteresis) 손실(자성체의 경우)에 의하여 고온의 열이 발생하게 되며, 이 열을 이용하여 피가열물질인 노즐부(10)를 가열하는 것을 말한다.In this case, induction heating means that a conductor such as a metal located in a coil in which a high frequency current flows generates high temperature heat due to eddy current loss and hysteresis loss (in the case of magnetic material). It means heating the nozzle unit 10.
한편, 단열부재(30)는 고주파코일(21)의 외주부에 밀폐가능하게 설치되어 고주파코일(21)에 의해 가열된 노즐부(10)의 열이 외부로 방출되는 것을 방지하고, 노즐부(10)를 일정한 온도로 유지시켜 준다.On the other hand, the heat insulating member 30 is installed to be sealed to the outer peripheral portion of the high frequency coil 21 to prevent the heat of the nozzle unit 10 heated by the high frequency coil 21 to be discharged to the outside, the nozzle unit 10 ) At a constant temperature.
본 발명인 노즐장치의 작용을 상세히 설명하면 다음과 같다.Referring to the operation of the nozzle device of the present invention in detail as follows.
용해로장치에서 공급된 금속용해물은 노즐부(10)의 노즐공(11)에 유입됨과 동시에 용해온도 이하로 급속히 낮아져 응고되는데, 이때 노즐부(10)의 두 온도감지센서(12)에서 각 부분의 온도를 감지하여 전자회로장치에 신호를 보내게 되고, 상기 전자회로장치는 그 신호를 받아 고주파발진수단(20)의 고주파코일(21)에 고주파전류를 공급하여 노즐부(10)를 소정의 온도로 가열하므로서 노즐공(11) 내부를 흐르는 금속용해물이 경화되는 것을 방지하게 된다.The metal lysate supplied from the smelting apparatus flows into the nozzle hole 11 of the nozzle unit 10 and solidifies rapidly below the melting temperature. At this time, each part of the two temperature sensors 12 of the nozzle unit 10 is solidified. The electronic circuit device senses the temperature and sends a signal to the electronic circuit device. The electronic circuit device receives the signal and supplies a high frequency current to the high frequency coil 21 of the high frequency oscillation means 20 to supply the nozzle unit 10 with a predetermined amount. By heating to a temperature, the metal melt flowing in the nozzle hole 11 is prevented from being cured.
이에 대해서 좀 더 부연하자면, 노즐부(10)의 두 온도감지센서(12)에서 노즐부(10)의 온도를 감지하였을 때 노즐부(10)의 인입부분보다 중간부분의 온도가 낮을 시에는 노즐부(10) 전방의 전방가열용 코일(21a)보다 노즐부(10) 후방의 후방가열용 코일(21b)에 더 높은 고주파전류를 공급하여 노즐부(10)의 전체 온도를 용해온도 이상으로 일정하게 유지시켜 주므로서 금속용해물이 경화되는 것을 방지하게 된다.In more detail, when the temperature of the nozzle unit 10 detects the temperature of the nozzle unit 10 by the two temperature sensors 12 of the nozzle unit 10, the nozzle is lowered when the temperature of the middle portion is lower than the inlet portion of the nozzle unit 10. By supplying a higher frequency current to the rear heating coil 21b behind the nozzle unit 10 than the front heating coil 21a in front of the unit 10, the entire temperature of the nozzle unit 10 is fixed above the melting temperature. It keeps to prevent the metal melt hardening.
한편, 고주파코일(21)의 외주부에는 단열부재(30)가 밀폐가능하게 설치되어 고주파코일(21)에 의해 가열된 노즐부(10)의 열이 외부로 방출되는 것을 방지하고, 노즐부(10)를 일정한 온도로 유지시켜 준다On the other hand, the heat insulating member 30 is installed on the outer circumferential portion of the high frequency coil 21 so as to be sealed to prevent the heat of the nozzle unit 10 heated by the high frequency coil 21 from being discharged to the outside, and the nozzle unit 10 Keep) at a constant temperature
따라서, 본 발명은 노즐부(10)의 외주부에 고주파발진수단(20)을 설치. 고주파를 발진시키므로서 노즐공(11)을 따라 흐르는 금속용해물을 일정한 온도로 유지시켜 작업효율 및 생산성을 크게 향상시킴은 물론이고, 노즐부(10)의 가열시간과 온도분위기를 정밀하게 제어함은 물론이고 고주파발진수단(20)에 의한 노즐부(10)의 가열속도를 크게 단축시킬 수 있어 양질의 제품을 다량으로 생산할 수 있으며, 또한 화염을 발생시킬 때 발생되는 오염을 완전히 방지할 수 있으므로 쾌적한 작업환경을 유지할 수 있는 매우 유용한 효과가 있다.Therefore, the present invention provides a high frequency oscillation means 20 in the outer peripheral portion of the nozzle unit 10. By oscillating high frequency, the metal melt flowing along the nozzle hole 11 is maintained at a constant temperature, thereby greatly improving work efficiency and productivity, as well as precisely controlling the heating time and temperature atmosphere of the nozzle unit 10. Of course, since the heating speed of the nozzle unit 10 by the high frequency oscillation means 20 can be greatly shortened, a large amount of high-quality products can be produced, and the pollution generated when generating a flame can be completely prevented. There is a very useful effect to maintain a comfortable working environment.
