[0033] Specifically, it is necessary to start the motor 4 first, and its output end drives the rotating rod 5 to rotate, and the active bevel gear 6 at the rear end of the rotating rod 5 rotates accordingly. The rotation of the active bevel gear 6 will drive the two driven bevel gears 8 to rotate, so that the two threaded rods 7 rotate in the groove 3.

[0035] Specifically, after starting motor 202, the output end of motor 202 drives the rotating shaft 203 to rotate, thereby rotating the driving gear 204 at the bottom of the rotating shaft 203. The rotation of the driving gear 204 will drive the rack 206 to slide horizontally in the sliding groove 205. When the rack 206 moves, the telescopic rods 207 on the left and right sides of its bottom will move accordingly, thereby driving the cross plate 208 and the processing plate 209 fixed to the bottom of the cross plate 208 to move together. By controlling the forward and reverse rotation of motor 202, the position of the processing plate 209 in the horizontal direction is adjusted so that it can perform processing operations on the mold steel clamped on the workbench 1.

After the mold steel is placed between the two clamping plates 10, the positions of the two clamping plates 10 are adjusted so that they are close to the mold steel until they are initially fixed. At this time, for some mold steels with irregular shapes or that require more stable clamping, the clamping mechanism on each clamping plate 10 can be further adjusted. By rotating the threaded rod 12, the clamping plate 13 moves downward to clamp different parts of the mold steel, so that the mold steel will not be displaced or shaken during processing;

[0041] After starting motor 202, the output end of motor 202 drives the rotating shaft 203 to rotate, thereby rotating the driving gear 204 at the bottom of the rotating shaft 203. The rotation of the driving gear 204 drives the rack 206 to slide horizontally in the sliding groove 205. When the rack 206 moves, the telescopic rods 207 on the left and right sides of its bottom will move accordingly, thereby driving the cross plate 208 and the processing plate 209 fixed to the bottom of the cross plate 208 to move together. By controlling the forward and reverse rotation of motor 202, the position of the processing plate 209 in the horizontal direction is adjusted so that it can perform processing operations on the mold steel clamped on the workbench 1.
