[0030] When the No. 1 motor 3 is running, the driving shaft 4 and the driving gear 5 will start to rotate. Since the driving gear 5 and the driven gear 6 are meshed with each other, the driven gear 6 will be driven by the rotation of the driving gear 5, so that the driven gear 6 and the driven shaft 7 as a whole will start to rotate with the upper side of the support frame 2 as the axis.

[0032] When the second motor 11 is running, the double-threaded lead screw 12 will start to rotate.

[0033] Among them, the left and right sides of the outer surface of the double-thread screw 12 are threadedly sleeved with movable blocks 13 located inside the hollow plate 9. There are two movable blocks 13, and the lower surfaces of the two movable blocks 13 are movably connected to the inner surface of the hollow plate 9.

[0034] When the double-threaded lead screw 12 rotates, the two movable blocks 13 start to move away from each other under the drive of the double-threaded lead screw 12 .

[0035] Among them, the outer surfaces of the front and rear sides of the two movable blocks 13 are hinged with connecting rods 14, the other end of the connecting rods 14 is hinged with hinged plates 15, the outer surface of the hinged plates 15 is fixedly connected with connecting frames 16, the number of connecting frames 16 is two, the outer ends of the two connecting frames 16 penetrate the hollow plate 9 and extend to the outside of the hollow plate 9, the outer surfaces of the two connecting frames 16 are movably connected to the inner surface of the hollow plate 9.

[0037] The left and right sides of the upper surface of the hollow plate 9 are movably connected with clamping blocks 17 . There are two clamping blocks 17 . The outer surfaces of the two clamping blocks 17 are fixedly connected to the two connecting frames 16 , respectively.

[0043] The working principle and use process of this utility model:

[0044] First, the operator places the undrilled mold on the upper surface of the hollow plate 9 and then starts the No. 2 motor 11. As the No. 2 motor 11 runs, the double-threaded screw 12 starts to rotate, which causes the two movable blocks 13 to start moving away from each other under the drive of the double-threaded screw 12 and the limit of the inner surface of the hollow plate 9. During the movement of the two movable blocks 13, the connecting rod 14 starts to rotate under the drive of the movable blocks 13, and the other end of the connecting rod 14 drives the hinged plate 15, so that the two hinged plates 15 as a whole start to move toward each other along the inner surface of the hollow plate 9. During this process, the two clamping blocks 17 gradually approach the outer surface of the mold and finally fix the mold, thereby ensuring the stability of the undrilled mold during the drilling process.

[0045] Then the operator starts the No. 1 motor 3. The operation of the No. 1 motor 3 will cause the driving shaft 4 and the driving gear 5 to start rotating. Since the driving gear 5 and the driven gear 6 are meshed with each other, the driven gear 6, the driven shaft 7 and the connecting block 8 will start rotating around the driven shaft 7 as the axis under the drive of the driving gear 5. This causes the mold fixed on the upper surface of the hollow plate 9 to tilt. When the tilt angle of the mold meets the drilling requirements, the operator starts the pneumatic cylinder 20 and the No. 3 motor 22. The operation of the pneumatic cylinder 20 will cause the mounting block 21 to move downward as a whole, and the operation of the No. 3 motor 22 will cause the rotating shaft 23 and the deep hole drill 24 to start rotating. Finally, under the joint action of the mounting block 21 and the deep hole drill 24, the deep hole processing operation of the mold is completed.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
