When the threaded rod 4 moves inside the fixed block 5, it will drive the mold 6 to move inside the fixed block 5 until it moves to a suitable position, thereby completing the adjustment of the position of the mold 6. When multiple molds 6 need to be adjusted synchronously, multiple handles can be rotated at the same time through the synchronization mechanism, reducing the tediousness of adjusting the molds 6 one by one, thereby improving work efficiency. The rotation mechanism can make the adjustment more labor-saving and easier to adjust.

When the threaded rod 4 is close to the adjustment block 3, it is slidably connected with the handle through the sliding plate 11, reducing the risk of the gear 10 sliding on the top of the rack 17. By using the synchronization mechanism, the staff can more conveniently and quickly adjust multiple molds 6 synchronously, reducing the tediousness of adjusting multiple molds 6, thereby improving the adjustment efficiency. The auxiliary rod 18 provides an additional support point for the threaded block 14, making the threaded block 14 more stable when moving.

[0041] Reference Figure 4 and Figure 5 The rotating mechanism includes a locking box 19 fixedly connected to the top of the workbench 1, a driving rod 20 is arranged inside the locking box 19, the driving rod 20 and the locking box 19 are slidingly arranged, a plurality of driving grooves 25 are equidistantly opened on the outer surface of the driving handle 13, the driving rod 20 is adapted to the driving grooves 25, and a locking piece is arranged inside the locking box 19.

Then the staff presses the driving rod 20 downward to make the driving handle 13 start to rotate, thereby adjusting the position of the mold 6. The driving rod 20 and the driving groove 25 can increase the rotation torque of the handle, and can convert a smaller force into a larger torque, thereby making it easier to operate the driving handle 13. When the driving rod 20 is rotated to a position where it is difficult to apply force, a plurality of driving grooves 25 are provided on the outer surface of the driving handle 13. At this time, the driving rod 20 is taken out and placed in the driving groove 25 where force is easy to apply. When the adjustment is completed, the driving rod 20 is taken out of the driving groove 25. , then pull the handle to drive the connecting plate 23 to move upward, and the connecting plate 23 moves upward to drive the slide plate 21 to move upward, and the slide plate 21 will squeeze the elastic member 22 upward, and the spring will generate elastic potential energy after being compressed.

When the slide plate 21 engages with the driving rod 20, the bottom of the slide plate 21 is set to an arc shape, so that the contact panel between the slide plate 21 and the driving rod 20 becomes larger, thereby better engaging and fixing the driving rod 20. When the slide plate 21 moves inside the engagement box 19, it is slidably connected with the slide groove 24 through the slider and the slide groove 24.

[0046] Working principle: first observe the position of the mold 6 inside the fixed block 5, and then drive the threaded rod 4 to rotate by turning the handle, and the threaded rod 4 is rotatably connected to the mold 6. When the threaded rod 4 moves inside the fixed block 5, it will drive the mold 6 to move inside the fixed block 5 until it moves to a suitable position, thereby completing the adjustment of the position of the mold 6. By turning the driving handle 13, the rack 17 moves on the top of the driving box 7, and the rack 17 is meshed with the gear 10, so that the gear 10 starts to rotate. After the gear 10 rotates, it drives the threaded rod 4 to rotate. By using the synchronization mechanism, the staff can more conveniently and quickly adjust multiple molds 6 synchronously.

[0047] The driving rod 20 is taken out from the locking box 19, and the driving groove 25 is adapted to the driving rod 20 so that the driving rod 20 is inserted into the driving groove 25. Then the staff presses the driving rod 20 downward to make the driving handle 13 start to rotate, thereby adjusting the position of the mold 6. The driving rod 20 and the driving groove 25 can increase the rotational torque of the handle, and a smaller force can be converted into a larger torque, thereby making it easier to operate the handle. By setting the bottom of the slide plate 21 to an arc shape, the contact panel between the slide plate 21 and the driving rod 20 becomes larger, thereby better fixing the driving rod 20.
