[0028] In one embodiment, a rectangular inner support frame is provided inside the mold positioning frame 6, and the inner support frame is located above the chip removal plate 9. Support frames 10 are welded to both the left and right sides of the mold positioning frame 6, and cylinders 11 are fixed on the support frames 10. One end of the cylinder 11 is fixed to a push plate 12 by screws, and several positioning posts 25 are welded to the surface of the push plate 12. One end of the positioning post 25 extending to the inner side of the mold positioning frame 6 is press-fitted with an elastic block 26.

This structure makes it easy to support the drive box 4, and the connecting posts allow the drilling bit 22 of the drive box 4 to extend toward the center area of ​​the mold positioning frame 6, thus meeting the drilling requirements of various parts of the precision mold.

[0034] Working principle: First, the precision mold to be drilled is placed inside the mold positioning frame 6. The cylinder 11 is extended, causing one end of the cylinder 11 to push several positioning pins 25 on its surface through the push plate 12 into the inner side of the mold positioning frame 6. Combined with the elastic blocks 26 on the end faces of the positioning pins 25, the precision mold is simultaneously clamped on both sides. When adjusting the drilling position, the first motor 7 is started, causing it to drive the first screw 8 at its output end to rotate. This causes the first threaded sleeve 15 below the mold positioning frame 6 to move along the surface of the first screw 8, allowing the mold positioning frame 6 to achieve Y-axis position adjustment under the guidance of the slide rod 5 and the slide sleeve 14. The second motor 17 of the start-up base 13 is activated, causing the second screw 16 at its output end to rotate. This causes the second threaded sleeve 18 on the bottom surface of the mold positioning frame 6 to move along the surface of the second screw 16, thereby adjusting the position of the mold positioning frame 6 in the X-axis direction. This allows for easy and flexible adjustment of the drilling position of the precision mold inside the mold positioning frame 6. When drilling, the electric cylinder 19 in the start-up drive box 4 is extended, and the third motor 21 in the lifting shell 20 is activated, causing the rotating drilling bit 22 to extend into the mold positioning frame 6 and drill holes in various parts of the precision mold inside the mold positioning frame 6. After drilling is completed, the precision mold can be removed.
