The internal cooling drill bit device comprises an upper template 1, wherein a sliding groove used for placing a material pressing rod is formed in the center of the upper template 1, a notch is downward, and the bottom of the groove is located above. The upper die base plate 2 is fixed below the upper die plate 1 through a fixing bolt, and a through hole which is communicated up and down is formed in the center of the upper die base plate. The spring 4 is placed in the through hole, and the spring gasket 8 is arranged at the bottom of the spring 4. One end of the material pressing rod 3 is abutted against the spring gasket 8, and the other end of the material pressing rod extends into the sliding groove and can move up and down. The core rod sleeve 7 is fixed below the upper die base plate 2 through screws. The center of the core rod sleeve 7 is vertically penetrated, and the core rod 5 is arranged at the center of the core rod sleeve 7. The inner wall of the core rod sleeve 7 is provided with a plurality of horizontal liquid inlet pipelines 71; the core rod 5 is provided with a plurality of corresponding cooling liquid channels 51. The cooling liquid channel 51 comprises three sections, a horizontal liquid inlet section 511, a vertical cooling section 512 and a horizontal liquid outlet section 513. The liquid inlet section comprises an inlet 5110, and the inlet 5110 is positioned on the outer wall of the core rod 5; the liquid outlet section 513 comprises an outlet 5130, and the outlet 5130 is positioned on the outer wall of the core rod 5. An annular clamping groove 72 is formed in the core rod sleeve 7, a circle of limiting plate 52 is arranged on the outer wall of the core rod 5, and the limiting plate 52 is inserted into the clamping groove 72.
