Specifically, the lower mold 25 is pushed during installation, moving from the second feeding auxiliary bracket 16 to slide on the lower support slider 18 and the second support limiting guide roller 19. Finally, the rear end of the lower mold 25 is attracted and fixed by the second magnet 706 on the magnetic steel plate and the second limiting plate frame 701, thus initially positioning and fixing the lower mold 25. Then, the connecting frame 22 is pushed by the third hydraulic telescopic rod 21 below, causing the connecting frame 22 to pass through the limiting... The slide rail 23 moves stably, thereby pushing the locking block 24 to engage and lock the lower mold 25. Similarly, the upper mold 26 is pushed during installation, moving from the first feeding auxiliary bracket 12 to the upper support slider 18 and the second support limiting guide roller 19. Finally, the rear end of the upper mold 26 is attracted and fixed by the first magnet 503 on the magnetic steel plate and the first limiting plate frame 501, thus initially positioning and fixing the upper mold 26. Then, the connecting frame 22 is pushed by the third hydraulic telescopic rod 21 above, so that the connecting frame 22 moves stably through the limiting slide rail 23, thereby pushing the locking block 24 to engage and lock the upper mold 26.

[0031] Auxiliary support seats 8 are fixedly installed on the front side of the upper mold seat 5 and the front side of the lower mold seat 7. A first card holder 9 is engaged on the upper auxiliary support seat 8. A first connecting frame 28 is fixedly connected to the front side of the first card holder 9. A first support card plate 10 is fixedly connected to the front side of the first connecting frame 28.

A first support limiting guide roller 17 is rotatably connected to the left and right sides of the second feeding auxiliary bracket 16 and the left and right sides of the first feeding auxiliary bracket 12.

[0032] When the first feeding auxiliary bracket 12 is installed on the upper auxiliary support seat 8, the first clamping bracket 9 is engaged with the auxiliary support seat 8, the first connecting bracket 28 is located between the auxiliary support seats 8, and the first connecting bracket 28 abuts against the upper mold seat 5, thereby serving as a locking and limiting position for the first feeding auxiliary bracket 12. When the second feeding auxiliary bracket 16 is installed on the lower auxiliary support seat 8, the second clamping bracket 13 is engaged with the auxiliary support seat 8, the second connecting bracket 29 is located between the auxiliary support seats 8, and the second connecting bracket 29 abuts against the lower mold seat 7, thereby serving as a locking and limiting position for the second feeding auxiliary bracket 16. The first support limiting guide roller 17 helps to slide on the first feeding auxiliary bracket 12 or the second feeding auxiliary bracket 16 during mold installation.

[0033] The upper mold base 5 includes a first limiting plate frame 501 fixedly installed at the lower end of the upper mold base 5 near the rear side. The first limiting plate frame 501 has a first opening slot 502. A first magnet 503 is embedded in the front side of the first limiting plate frame 501. A fixing frame 504 is fixedly connected to the rear side of the first limiting plate frame 501. A fourth hydraulic telescopic rod 505 is fixedly installed through the side wall of the fixing frame 504. A first push plate 506 is fixedly connected to the front end of the fourth hydraulic telescopic rod 505.

[0034] The first magnet 503 is used for the initial positioning and fixation of the upper mold 26 during sliding installation, which facilitates subsequent locking. The fourth hydraulic telescopic rod 505 pushes the first push plate 506 to act on the upper mold 26, which facilitates the upper mold 26 to detach from the adsorption and move and adjust for mold replacement.

[0035] The lower mold base 7 includes a second limiting plate frame 701 and a mounting base 702, which are fixedly installed on the upper end of the lower mold base 7 near the rear side. The mounting base 702 is located on the rear side of the second limiting plate frame 701. A fifth hydraulic telescopic rod 703 is fixedly installed on the mounting base 702.

A second magnet 706 is embedded in the front side of the second limiting plate frame 701.

[0036] The second magnet 706 is used for the initial positioning and fixation of the lower mold 25 during sliding installation, which facilitates subsequent locking and engagement. The fifth hydraulic telescopic rod 703 pushes the second push plate 704 onto the lower mold 25, which facilitates the lower mold 25 to detach from the adsorption and move for adjustment and mold replacement.

[0037] Combination Figures 1-7The specific usage process of the PP blister packaging box forming mold of this embodiment is as follows: When the first feeding auxiliary bracket 12 is installed on the upper auxiliary support seat 8, the first clip 9 is inserted into the auxiliary support seat 8, and the first connecting bracket 28 is located between the auxiliary support seats 8, and the first connecting bracket 28 abuts against the upper mold seat 5, thereby serving as a locking and limiting position for the first feeding auxiliary bracket 12. When the second feeding auxiliary bracket 16 is installed on the lower auxiliary support seat 8, the second clip 13 is inserted into the auxiliary support seat 8, and the second connecting bracket 29 is located between the auxiliary support seats 8, and the second connecting bracket 29 abuts against the lower mold seat 7. The lower mold 25 is pushed during installation, moving from the second feeding auxiliary bracket 16 to the lower support slider 18 and the second support limiting guide roller 19. Finally, the rear end of the lower mold 25 is attracted and fixed by the second magnet 706 on the magnetic steel plate and the second limiting plate frame 701, thus initially positioning and fixing the lower mold 25. The operator then operates the button panel, which pushes the connecting frame 22 through the third hydraulic telescopic rod 21 below. This causes the connecting frame 22 to move stably along the limiting slide rail 23, thereby pushing the locking block 24 to engage and lock the lower mold 25. That is, the lower locking block 24 is completely inserted into the lower mold 25, and the lower mold 25 contacts the lower connecting frame 22. When the upper mold 26 is installed, it is pushed from the first feeding auxiliary bracket 12 to slide on the upper support slider 18 and the second support limiting guide roller 19. Finally, the rear end of the upper mold 26 is attracted and fixed by the first magnet 503 on the first limiting plate frame 501 through the magnetic steel plate, and the upper mold 26 is initially positioned and fixed. The operator operates the button panel, and pushes the connecting frame 22 under the action of the upper third hydraulic telescopic rod 21, so that the connecting frame 22 moves stably through the limiting slide rail 23, thereby pushing the locking block. The upper mold 26 is locked in place by the upper locking block 24, meaning the upper locking block 24 is fully engaged inside the upper mold 26. The upper mold 26 and the upper connecting frame 22 are in contact. By setting a pressure sensor or laser rangefinder, the connecting frame 22 is controlled to move to an appropriate position and then stop. This part of the technology is an existing technology structure. The fourth hydraulic telescopic rod 505 pushes the first push plate 506 to act on the upper mold 26, which facilitates the upper mold 26 to detach from the adsorption and move for adjustment to change the mold. The fifth hydraulic telescopic rod 703 pushes the second push plate 704 to act on the lower mold 25, which facilitates the lower mold 25 to detach from the adsorption and move for adjustment to change the mold.
