본 발명은 사출금형용 온도조절장치에 관한 것으로, 좀더 상세히는 사출금형의 바람직한 작업온도를 일정하게 유지하도록 몸체 저부에 지그재그 공간부와 히터를 마련한 순환부를 별도로 마련하여 펌프에 의해 열교환매체의 순환속도를 향상시킬 수 있도록 하는 것이다.The present invention relates to a temperature control apparatus for an injection mold, and more particularly, to provide a zigzag space part and a circulation part provided with a heater at the bottom of the body to maintain a constant working temperature of the injection mold. To improve.

일반적으로 플라스틱 사출성형기는 플라스틱 성형재료를 가열하여 연하게 한 뒤 이것을 차가운 사출금형에 재빨리 밀어넣어 성형하는 것으로, 열가소성 수지의 성형에 많이 사용되며 또한, 플라스틱 사출금형에 공급되는 성형재료로는 플라스틱에 안료나 안정제를 첨가하여 절단해 만든 입자 모양의 칩이 쓰이며, 플랜지가 후퇴했을 때 칩이 호퍼에서 자동적으로 실린더 속으로 공급, 가열되어 유동상태가 되고 스크루가 있는 부분에서는 성형재료가 가는 통로를 지나며 균등하게 가열된다.In general, the plastic injection molding machine heats and softens the plastic molding material and quickly pushes it into a cold injection mold. The plastic injection molding machine is commonly used for molding thermoplastic resins, and the molding material supplied to the plastic injection mold is plastic. Particle chips made by cutting with pigment or stabilizer are used.When the flange is retracted, the chips are automatically fed into the cylinder from the hopper and heated to become a fluid state. Heated evenly.

그리고, 노즐로부터 닫힌 사출금형 속으로 압입되며, 사출금형에는 냉각수를 순환시켜 적당한 온도를 유지해야 하며, 압입이 완료되어 성형물이 냉각고화된 뒤 가동판이 후퇴하여 사출금형이 열리면 장치가 작동하여 성형물이 나오게 된다.Then, it is pressed into the injection mold closed from the nozzle, and the injection mold has to maintain a proper temperature by circulating the cooling water.After the injection is completed, the molding is cooled and solidified, and the movable plate is retracted to open the injection mold. Come out.

따라서, 사출성형기에 온도조절기를 부설하여 물이나 기름등의 열교환매체를 금형에 순환 공급시켜 사출금형의 온도를 일정하게 유지하고 있다.Therefore, a temperature controller is installed in the injection molding machine to circulate and supply a heat exchange medium such as water or oil to the mold to maintain a constant temperature of the injection mold.

종래의 사출금형용 온도조절기는 몸체 내부에 히터를 마련하고 열교환매체를 채워 상기 히터에 의해 열교환매체를 설정된 온도로 가열하여 순환시키기 위한 펌핑수단과 그 연결관에 의해 사출금형을 소정의 온도로 유지가능케 하는 것이다.Conventional injection mold temperature controller provides a heater in the body and filling the heat exchange medium to maintain the injection mold at a predetermined temperature by the pumping means and the connection pipe for heating and circulating the heat exchange medium to the set temperature by the heater. It is.

이러한 통상의 사출금형용 온도조절기는 몸체 내부의 히터를 가열하면 히터의 표면에서 몸체 내부의 전체공간으로 전달시키게 하므로 열교환매체로 열전달이 늦어지는 문제점이 발생하며, 그로인해 히터의 가열온도를 높이게 하거나 열교환매체의 소정온도가 될때까지 대기하여야 하는 문제점이 발생하며 또한, 상기 펌프에 의한 순환속도를 증가시키면 사출금형에 원하는 소정온도를 유지하기가 어려운 문제점이 있었다.The conventional injection mold temperature controller causes a problem that the heat transfer to the heat exchange medium is delayed when the heater inside the body is heated, thereby transferring it from the surface of the heater to the entire space inside the body, thereby increasing the heating temperature of the heater or heat exchange. There is a problem of waiting for a predetermined temperature of the medium, and increasing the circulation speed by the pump has a problem that it is difficult to maintain a desired temperature in the injection mold.

상기 히터의 열이 열교환매체로 열의 전달이 늦어지는 현상으로 인해 상기 히터의 표면에서 탄화현상이 일어나는 문제점과 그로인한 열교환매체의 타는 냄새가 발생하게 되는 것이다.Due to the phenomenon that the heat of the heater is delayed in the transfer of heat to the heat exchange medium, the carbonization phenomenon occurs on the surface of the heater and the burning smell of the heat exchange medium is generated.

따라서, 상기 온도조절기의 몸체 내부에 히터를 마련하고 열교환매체를 채우므로 몸체 내부에 차지하는 히터의 표면적이 낮아 몸체 내부에 마련된 열교환매체 를 가열하는데 시간이 많이 소요되는 문제점과 열교환매체의 순환속도가 늦어지면 사출금형을 소정의 온도로 유지하는데 어려움이 있었다.Therefore, since the heater is provided inside the body of the temperature controller and the heat exchange medium is filled, the surface area of the heater occupying the inside of the body is low, so that it takes a long time to heat the heat exchange medium provided in the body and the circulation speed of the heat exchange medium is slow. There was a difficulty in maintaining the surface injection mold at a predetermined temperature.

본 발명은 상술한 종래의 문제점을 해결하기 위한 것으로서, 위와같이 사출금형용 온도조절기의 몸체 내부에 마련된 열교환매체의 순환속도를 향상시키기 위한 것으로 몸체 내부와 사출금형과 통하는 별도의 순환부를 마련하고 순환부 내부에 다수개의 격판을 지그재그로 배열한 공간부를 마련하여 상기 공간부에 히터를 설치하여 상기 순환부의 지그재그로 배열된 공간부 내에서 히터의 표면적을 높여 히터에 의한 열을 열교환매체로 신속하게 전달가능케 하므로 펌프의 순환속도를 향상시키기 위한 것인데,The present invention is to solve the above-described problems, to improve the circulation rate of the heat exchange medium provided in the body of the temperature controller for injection mold as described above to provide a separate circulation portion communicating with the body and the injection mold and the circulation portion By arranging a plurality of diaphragms in the space therein and installing a heater in the space to increase the surface area of the heater in the space arranged in the zigzag of the circulation portion to quickly transfer heat by the heater to the heat exchange medium So to improve the circulation speed of the pump,

By increasing the surface area of the heat exchange medium 7 and the heater 23 by the diaphragm 21 arranged in a zigzag ()) to improve the heat transfer from the surface of the heater 23 to the heat exchange medium (7).

또한, 펌프(3)에 의해 사출금형(2)을 거쳐 투입관(5)을 통해 순환부(20)의 투입구(12)로 투입된 열교환매체(7)는 다시 다수개의 히터(23)에서 열전달되어 순환부(20)의 지그재그로 배열된 격판(21)의 공간부(22)와 히터(23)를 거치면서 한층 더 효과를 나타내며 상기 순환부(20)의 양끝단에 형성된 배출구(11)를 통해 열교환매체(7)는 몸체(10)로 배출된다.In addition, the heat exchange medium 7 introduced through the injection mold 2 by the pump 3 into the inlet 12 of the circulation unit 20 through the inlet pipe 5 is heat-transferd from the plurality of heaters 23 again. Passing through the space portion 22 and the heater 23 of the diaphragm 21 arranged in a zigzag of the circulation portion 20 has a further effect and through the discharge port 11 formed at both ends of the circulation portion 20 The heat exchange medium 7 is discharged to the body 10.

상기 순환부(20)에서 배출된 열전달된 열교환매체(7)는 배출구(11)의 상부에 형성된 평판(13)에 의해 몸체(10) 내부에서 분산을 용이하게 하여 상기 펌프(3)에 의해 열교환매체(7)는 배출관(4)을 통해 사출금형(2)으로 이동가능케 하는 것이다.The heat-transferd heat exchange medium 7 discharged from the circulation part 20 facilitates dispersion in the body 10 by a flat plate 13 formed on an upper portion of the discharge port 11, thereby exchanging heat by the pump 3. The medium 7 is movable to the injection mold 2 through the discharge pipe 4.

따라서, 상기 순환부(20)의 내부에 다수개의 격판(21)을 지그재그 배열한 공간부(22)에 마련된 히터(23)에 의해 순환부(20)에 위치한 열교환매체(7)는 격판(21)에 의해 공간부(22)내에서 히터(23)의 표면적을 높여 열교환매체(7)로 쉽게 열전달이 용이하도록 하여, 상기 지그재그 배열된 격판(21)을 거치면서 열교환매체(7)의 열전달을 한층 더 향상시키므로 펌프(3)에 의한 열교환매체(7)의 순환속도를 증가시킬 수 있는 이점이 있는 것이다.Therefore, the heat exchange medium 7 located in the circulation part 20 is provided by the heater 23 provided in the space part 22 in which the plurality of diaphragms 21 are zigzag arranged inside the circulation part 20. By increasing the surface area of the heater 23 in the space 22 to facilitate heat transfer to the heat exchange medium (7), the heat transfer of the heat exchange medium (7) while passing through the zigzag arranged plate 21 Since it is further improved, there is an advantage that can increase the circulation speed of the heat exchange medium 7 by the pump 3.

따라서, 상기 펌프(3)에 의해 열교환매체(7)의 순환속도를 향상시키면 상기 히터(23)의 표면에서 열교환매체(7)로 열전달시 탄화현상을 제거할 수 있으며 그로인한 타는 냄새를 제거 할 수 있는 것이다.Therefore, when the circulation speed of the heat exchange medium 7 is improved by the pump 3, the carbonization phenomenon may be removed during heat transfer from the surface of the heater 23 to the heat exchange medium 7, thereby removing the burning odor. It can be.

따라서, 본 발명은 상기한 바와 같이 사출금형과 별도로 형성하는 온도조절장치의 내부에 별도의 순환부를 마련하여 그 내부에 격판을 지그재그로 배열한 공간부를 마련하여 상기 지그재그 배열된 공간부에 각각의 히터를 마련케 하여 공간부 내에서 히터의 표면적을 높여 히터에 의한 열이 열교환매체로 전달을 용이하게 하여 히터에서 열교환매체로 빠른 열전달을 가능케 하여 펌프에 의한 순환속도를 향상시킬 수 있는 이점과 그로인한 향상된 순환속도에 의해 히터의 표면에서 탄화현상이 일어나는 문제점과 그로인한 열교환매체의 타는 냄새를 방지하게 하는 이점이 있는 것이다.Therefore, the present invention provides a separate circulation portion in the temperature control device formed separately from the injection mold as described above to provide a space portion zigzag arranged therein each heater in the zigzag spaced space portion By increasing the surface area of the heater in the space portion to facilitate the transfer of heat by the heater to the heat exchange medium to enable fast heat transfer from the heater to the heat exchange medium to improve the circulation speed by the pump and thereby The improved circulation speed has the advantage of preventing carbonization on the surface of the heater and the burning odor of the heat exchange medium.
