The outer surface of each second ball 306 contacts the inner wall of the limit box 302. The inner bottom walls of the two moving boxes 303 are fixedly installed with limit springs 307. The tops of the two limit springs 307 are fixedly installed with connecting plates 308. The upper surfaces of the two connecting plates 308 are respectively in contact with the outer surfaces of the two first balls 305. The limit spring 307 and the connecting plate 308 play a limiting role to prevent the second ball 306 from moving freely inside the moving box 303. The top ends of the two threaded rods 304 penetrate the limit box 302 and are fixedly installed with a rotating disk 309. By rotating the rotating disk 309, the threaded rod 304 is moved upward, so that the first ball 305 releases the squeezing limit on the second ball 306, and then the worker can move the limit box 302 upward. The upper surfaces of the two fixed frames 2118 are fixedly installed with a placement box 310. The interiors of the two placement boxes 310 are slidably connected with rollers 311. The outer surface of the rotating disk 309 is provided with grooves arranged at equal distances for the rollers 311 to engage. Clamped inside the rotating disk 309, the outer surfaces of the two rollers 311 are fixedly installed with pull rods 312, and the ends of the two pull rods 312 away from the rollers 311 are extended to the outside of the placement box 310, and the interiors of the two placement boxes 310 are clamped with pins 313, and the bottom ends of the two pins 313 are extended to the interior of the placement box 310. By providing an adjustment mechanism 3, after the core mold body 12 is installed, the worker can adjust the position of the core mold body 12 without disassembling the core mold body 12, so that when the core mold body 12 has a position deviation, the position of the core mold body 12 can be adjusted more conveniently, further increasing the installation and fixing efficiency of the core mold body 12.

[0051] See also Fig.12Two telescopic columns 314 are fixedly installed on the inner top walls of the two fixed frames 2118, and the telescopic ends of each telescopic column 314 are fixedly connected to the upper surface of the limit frame 2119. The installation of the telescopic columns 314 serves to limit the moving trajectory of the limit frame 2119, thereby ensuring the stability of the movement of the limit frame 2119.

[0052] See also Fig.14 The inner bottom walls of the two moving boxes 303 are fixedly installed with telescopic shafts 315, and the telescopic ends of the two telescopic shafts 315 are fixedly connected to the bottom surface of the connecting plate 308. The installation of the telescopic shafts 315 serves to limit the moving trajectory of the connecting plate 308, thereby ensuring the stability of the movement of the connecting plate 308.

[0053] The specific implementation of this embodiment is as follows: when there is a position deviation in the front-to-back direction after the core mold body 12 is installed, the worker pulls the pin 313 out of the inside of the placement box 310, and then the worker pulls the pull rod 312, so that the pull rod 312 drives the roller 311 away from the rotating disk 309, so that the rotating disk 309 drives the threaded rod 304 to rotate, so that the threaded rod 304 moves upward, and then the threaded rod 304 drives the first ball 305 to move upward, so that the first ball 305 releases the limiting effect on the second ball 306, and then the worker pulls the limit box 302 upward, so that the limit box 302 slides on the outer surface of the moving box 303, so that the limit box 302 drives the limit frame 2119 to move upward. The worker moves up to release the clamping limit of the steel frame 11, and then corrects the position of the core mold body 12 by moving the core mold body 12 and the base 2114. When the position of the core mold body 12 is corrected, the elastic force of the fixed spring 301 is used to make the limit frame 2119 cooperate with the base 2114 to clamp and limit the steel frame 11. Then the worker rotates the rotating disk 309 in the opposite direction, thereby driving the first ball 305 to limit the second ball 306 here, and then fixes the moving box 303 to the limit box 302. Then the worker clamps the roller 311 into the inside of the rotating disk 309 and inserts the pin 313 into the inside of the pull rod 312 to complete the correction of the position of the core mold body 12.
