본 발명은 사출금형의 슬라이드 코어 냉각장치에 관한 것으로, 상세하게는 냉각장치의 설치 및 작업성이 향상되고 높은 냉각효율을 얻을 수 있는 사출금형의 슬라이드 코어 냉각장치이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide core cooling apparatus of an injection mold, and more particularly, to a slide core cooling apparatus of an injection mold which can improve installation and workability of a cooling apparatus and obtain high cooling efficiency.

일반적으로 사출금형 슬라이드 코어를 냉각하기 위해서는 냉각하고자 하는 부분에 드릴링 작업으로 냉각수 유입관과 냉각수 배출관을 각각 형성하고, 냉각수 유입관을 통하여 냉각수를 공급하여 냉각수가 냉각수 배출관을 통해 배출 되도록 구성되어 있다.In general, in order to cool the injection mold slide core, the cooling water inlet pipe and the cooling water discharge pipe are respectively formed by a drilling operation on the portion to be cooled, and the cooling water is supplied through the cooling water inlet pipe so that the cooling water is discharged through the cooling water discharge pipe.

그러나, 상기와 같은 종래기술에 따른 사출금형의 슬라이드 코어 냉각장치는 다음과 같은 문제점이 있다.However, the slide core cooling apparatus of the injection mold according to the prior art as described above has the following problems.

첫째, 냉각수 유입관과 배출관을 형성하기 위하여 코어에 각각 구멍을 뚫는 작업을 해야 하는 불편함이 있다. First, in order to form the cooling water inlet pipe and the discharge pipe, there is an inconvenience of having to drill holes in the cores, respectively.

또한, 냉각수 유입관과 냉각수 배출관을 상호 연통하는 연결통로를 별도로 형성하여야 하므로, 작업성이 현저히 저하된다.In addition, since the connection passage for communicating the cooling water inlet pipe and the cooling water discharge pipe must be formed separately, workability is significantly reduced.

둘째, 슬라이드 코어가 휘어진 구조를 갖는 경우에 냉각수 유입관과 배출관을 드릴링 하는 작업은 극히 어려워진다.Second, when the slide core has a curved structure, drilling of the coolant inlet and outlet pipes becomes extremely difficult.

셋째, 냉각수가 단순히 유입관과 배출관으로 유동하면서 냉각시키는 구조이므로, 냉각효율을 높일 수 없다.Third, since the cooling water is simply cooled while flowing to the inlet and outlet pipes, the cooling efficiency cannot be increased.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 휘어진 구조를 함으로서 작업성이 현저히 향상된 사출금형의 슬라이드 코어 냉각장치를 제공하는 것을 목적으로 한다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a slide core cooling apparatus of an injection mold, which has remarkably improved workability by having a curved structure.
