본 발명은 다이캐스팅 머신을 위한 냉각수 공급구조에 관한 것으로서, 좀더 상세하게는 직렬로 설치되는 복수개의 다이캐스팅 머신을 이용하는 다이캐스팅 주조공법에 있어서 각각의 다이캐스팅 머신에 냉각수를 공급 및 배출하여 주기 위한 냉각수 공급구조에 관한 것이다.The present invention relates to a cooling water supply structure for a die casting machine, and more particularly, to a cooling water supply structure for supplying and discharging cooling water to each die casting machine in a die casting casting method using a plurality of die casting machines installed in series. It is about.

통상의 다이캐스팅 머신은 작업과정에서 상당한 고열이 발생하는 장비로서 다이캐스팅 머신의 주조부에는 지속적인 냉각수의 공급 및 배출작용이 이루어져야만 하는데, 종래 다이캐스팅 머신의 냉각수 공급체계는 냉각수를 공급하기 위한 냉각수 공급배관과 냉각수를 배출하기 위한 냉각수 배출배관을 2열로 병설한 다음 다이캐스팅 머신에 마련되는 냉각수 유입관을 냉각수 공급배관에 연결하고 역시 다이캐스팅 머신에 마련되는 냉각수 유출관을 냉각수 배출배관에 연결하여 냉각수의 공급 및 배출작용이 이루어지도록 하고 있다.Conventional die casting machine is a device that generates a considerable amount of heat in the process of operation, and the casting part of the die casting machine has to continuously supply and discharge the cooling water. In the conventional die casting machine, the cooling water supply system and the cooling water supply pipe for supplying the cooling water The cooling water discharge pipe for discharging the cooling water is provided in two rows, and the cooling water inlet pipe provided in the die casting machine is connected to the cooling water supply pipe, and the cooling water outlet pipe provided in the die casting machine is connected to the cooling water discharge pipe to supply and discharge the cooling water It is working.

상기한 바와 같은 냉각수 공급체계는 다이캐스팅 머신을 직렬로 설치하여 사용할 경우 냉각수의 공급원으로부터 가장 근접한 다이캐스팅 머신에서 냉각수의 공급 및 배출이 가장 빨리 이루어질 수밖에 없는 체계이므로 냉각수 공급원에 근접한 다이캐스팅 머신과 냉각수 공급원으로부터 떨어진 다이캐스팅 머신은 냉각수의 유속편차가 매우 심해진다는 폐단이 있었으며, 그로 인해 각각의 다이캐스팅 머신 간에 균일한 주조조건이 이루어지지 않았을 뿐만 아니라 냉각효율이 떨어진다는 등의 문제점이 지적되어 왔다.As described above, when the die casting machine is installed in series, the supply and discharge of the coolant is quickest in the die casting machine closest to the source of the coolant. Therefore, the coolant supply system is separated from the die casting machine and the coolant source close to the source of the coolant. The die casting machine has a closed end that the flow rate of the cooling water is very severe, and as a result, problems such as not only uniform casting conditions between the die casting machines but also low cooling efficiency have been pointed out.

본 발명은 전술한 바와 같은 종래 냉각수 공급체제의 제반 문제점을 일소하기 위해 창출된 것으로서, 직렬로 설치된 복수개의 다이캐스팅 머신 사이에 발생되 는 냉각수의 유속편차를 방지할 수 있도록 함으로써 각각의 다이캐스팅 머신에서 균일한 주조조건으로 제품을 생산할 수 있도록 함과 아울러 냉각효율을 극대화할 수 있도록 함에 기술적 과제의 주안점을 두고 완성한 다이캐스팅 머신의 냉각수 공급구조를 제공하고자 한다.
The present invention was created to eliminate all the problems of the conventional cooling water supply system as described above, and it is possible to prevent the flow rate deviation of the cooling water generated between a plurality of die casting machines installed in series to ensure uniformity in each die casting machine.
