Abstract

The present invention relates to a core-cooling device for an injection mold which molds plastic injection-molded articles. More particularly, the present invention relates to a core-cooling device for an injection mold, wherein cooling water is efficiently supplied to circulate through a cooling water channel of a core and thus uniformly and quickly cool the core. The core-cooling device for an injection mold according to the present invention comprises: a basic cooling water pipe which is formed on a lower disk (20) and which includes a cooling water inlet (110) and a cooling water outlet (120); and core-cooling water pipes (200) in communication with the cooling water inlet (100) and the cooling water outlet (120) of the basic cooling water pipe so as to enable cooling water to circulate through the interior of a lower core (30). Baffle pipes (210) divided into left and right sections are coupled to respective core-cooling water pipes (200). The cooling water inlet (110) of the basic cooling water pipe enables cooling water to be simultaneously fed into each of the core-cooling water pipes (200) via distribution pipes (111) connected to the lower ends of baffle pipes (210), respectively. The cooling water outlet (120) of the basic cooling water pipe is connected to lower portions of the core-cooling water pipes (200) so as to discharge, to the outside from the core-cooling device, the cooling water which is fed through the lower ends of the baffle pipes (210), discharged from upper portions of the core-cooling water pipes (200), and falling down toward the lower portions of the core-cooling water pipes (200) in order to cool the lower core (30).
