종래, 사출성형기 등의 성형기에 있어서는, 가열실린더 내에 있어서 가열되어 용융된 성형재료로서의 수지를, 고압으로 사출하여 금형장치의 캐비티 공간에 충전하고, 이 캐비티 공간 내에 있어서 냉각하여 고화시킴으로써 성형품이 성형되도록 되어 있다. Conventionally, in molding machines such as injection molding machines, the resin as a molding material heated and melted in a heating cylinder is injected at a high pressure to be filled in the cavity space of the mold apparatus, and cooled and solidified in the cavity space so that the molded article is molded. It is.
이 경우, 상기 사출성형기는 금형장치, 형체(型締)장치 및 사출장치를 가지며, 상기 형체장치는, 고정플래튼 및 가동플래튼을 구비하고, 형체용 실린더가 가동플래튼을 진퇴시킴으로써 금형장치의 형폐(型閉), 형체(型締) 및 형개(型開)를 행한다.In this case, the injection molding machine has a mold apparatus, a mold clamping apparatus and an injection apparatus, and the mold clamping apparatus includes a stationary platen and a movable platen, and the mold cylinder is moved back and forth by the movable platen. Mold closing, mold opening, and mold opening are performed.
한편, 상기 사출장치는, 수지를 가열하여 용융시키는 가열실린더, 및, 이 가열실린더의 전단(前端)에 장착되어, 용융된 수지를 사출하는 사출노즐을 구비하고, 상기 가열실린더 내에 스크루가 회전 가능하게, 또한, 진퇴 가능하게 설치된다. 그리고, 이 스크루를 후단(後端)에 설치된 구동부에 의해서 회전시켜서, 수지를 스크루의 전방(前方)에 축적함으로써, 이 스크루가 소정의 위치까지 후퇴함으로써 수지의 계량이 행하여진다. 이때, 수지는, 가열실린더 내에 있어서 가열되고, 용융되어서 상기 스크루의 전방에 축적된 수지의 압력에 의해서, 스크루는 후퇴된다. 그리고, 상기 구동부에 의해서 전진시킴으로써 사출노즐로부터 수지가 사출된다. 또한, 상기 가열실린더의 주위에는 가열장치가 장착되어, 가열실린더를 소정의 온도까지 가열하도록 되어 있다.On the other hand, the injection apparatus includes a heating cylinder for heating and melting the resin, and an injection nozzle mounted at a front end of the heating cylinder and injecting the molten resin, wherein the screw can be rotated in the heating cylinder. In addition, it is installed so that advancement is possible. And this screw is rotated by the drive part provided in the rear end, and resin is accumulated in front of a screw, and this screw retreats to a predetermined position, and resin is measured. At this time, the resin is heated in the heating cylinder, and the screw is retracted by the pressure of the resin that is melted and accumulated in front of the screw. The resin is injected from the injection nozzle by advancing by the drive unit. In addition, a heating device is mounted around the heating cylinder to heat the heating cylinder to a predetermined temperature.
이러한 경우, 상기 실린더는 사출에 사용되는 수지의 종류에 따라 각 부분별로 요구되는 온도를 달리한다. 즉, 도 1에 도시한 것과 같이 실린더의 각 구간별로 온도의 분포를 달리하게 된다. In this case, the cylinder varies in temperature required for each part according to the type of resin used for injection. That is, as shown in FIG. 1, the temperature distribution is changed for each section of the cylinder.
이와 같이 실린더의 각 구간별 온도 분포를 조절하기 위하여, 기존에는 특허문헌 1의 "사출장치 및 사출장치의 가열방법" (대한민국 공개특허 제10-2006-0085957호)와 같이 가열실린더의 외주(外周)에 있어서의 냉각장치에 인접한 영역에 유도가열식 가열장치를 장착함으로써, 가열실린더의 온도를 한결같이, 또한, 적절한 값으로 할 수 있고, 또한, 가열실린더의 온도를 신속하게 변화시킬 수 있도록 하는 발명이 개시되어 왔다. In this way, in order to adjust the temperature distribution for each section of the cylinder, conventionally, as described in Patent Document 1, "The heating method of the injection apparatus and the injection apparatus" (Korean Patent Publication No. 10-2006-0085957), the outer periphery of the heating cylinder By installing an induction heating type heater in a region adjacent to the cooling device in the above), the invention is capable of making the temperature of the heating cylinder constant and at an appropriate value, and also allows the temperature of the heating cylinder to be changed quickly. Has been disclosed.
그러나, 이러한 기존의 발명은 사출기의 실린더의 외부 역시 높은 고온이 되므로, 사출기가 설치된 실내로 많은 열이 방출되어 작업자가 별도의 방열복 등을 착용하지 않고서는 장시간 작업이 불가능할 정도로 실내의 온도가 고온이 되어 작업환경이 열악해 지는 문제점이 있었다. 이러한 문제점은 특히 하나 이상의 다수의 사출 장치를 설치하여 운영하는 경우 더욱 크게 나타나게 된다. However, since the existing invention is also a high temperature outside the cylinder of the injection machine, a lot of heat is released to the room where the injection machine is installed, so that the indoor temperature is high enough that the operator can not work for a long time without wearing a separate heat-resistant suit, etc. There was a problem that the working environment is poor. This problem is particularly significant when one or more injection apparatuses are installed and operated.
한편, 사출기에서 금형의 냉각 및 온도 제어를 위하여 종래에는 냉각수를 이용하는 방법과, 냉각유를 이용하는 방법 그리고 질소가스를 이용하여 금형을 냉각시키는 방법들이 있었다. 그러나 상기한 방법 중 냉각수를 이용하는 방법은 금형내부의 냉각수라인에 부식이 발생되어 금형의 수명이 단축되고, 냉각수를 주기적으로 교체해 주어야하는 불편함과 냉각수의 특성상 100℃이상의 온도로는 금형의 온도제어가 불가능하며, 또한 금형의 교체 시 냉각수가 외부로 흘러내려 작업장의 주위가 불결해지는 문제점과, 상기 냉각유를 사용하는 방법은 100℃이상의 고열로서 사용되는바 이에 따른 탄화현상의 발생으로 인하여 금형 및 장비들의 수명이 저하되며,금형교체시 냉각유가 흘러내려 작업장의 주위가 불결해지는 문제점이 발생되었다.On the other hand, there are conventional methods for cooling the mold and temperature control in the injection molding machine using a cooling water, a method using a cooling oil, and a method of cooling the mold using nitrogen gas. However, the method using the cooling water of the above method is to reduce the life of the mold due to corrosion occurs in the cooling water line inside the mold, and to control the temperature of the mold at a temperature above 100 ℃ due to the inconvenience of having to replace the cooling water periodically and the nature of the cooling water And the problem that the surroundings of the workplace are unclean because the coolant flows to the outside when the mold is replaced, and the method of using the coolant is used as a high temperature of 100 ° C. or higher. The service life of the equipment is reduced, and when the mold is replaced, the coolant flows down and the surroundings of the work site are dirty.
또한, 상기한 기존 발명들은 단지 금형의 냉각 및 온도 제어를 위한 것이나, 일반적으로 금형은 실내에서 그 노출 면적이 적어 실내로의 열 방출이 비교적 적을 뿐만 아니라, 작동 부위의 특성상 커버 등으로 밀페되어 설치되는 경우가 대부분인 점을 고려할 때 실내로의 열 방출이 더욱 적으므로, 열방출에 의한 작업실 내의 온도 상승으로 인한 문제점이 비교적 작게 발생하게 되므로, 작업실 내의 온도 조절을 위한 방법으로는 대단히 미흡하다는 문제점이 있었다. In addition, the above-mentioned existing inventions are merely for cooling and temperature control of the mold, but in general, the mold has a small exposed area in the room, so that the heat dissipation into the room is relatively low, and due to the nature of the working part, the mold is sealed and installed. Considering that most of the cases are less heat discharge into the room, the problem caused by the temperature rise in the work room due to the heat release occurs relatively small, so the method for controlling the temperature in the work room is very insufficient. there was.
