[0042] Please pay special attention to Figures 1 to 10, the adjustment control component 7 includes first sliding blocks 701 slidably connected to both sides of the outer surface of the guide frame. A driven plate is fixedly installed on the side surface of the first sliding block 701, a hydraulic cylinder 702 is fixedly installed on the side surface of the driven plate, a driven frame 703 is fixedly installed on the upper surface of the sliding block 701. V-shaped rods 704 are rotatably connected to both sides of the inner side wall of the driven frame 703. A connecting column 705 is fixedly installed on the side surface of the two V-shaped rods 704. A first electric push rod 706 is arranged on the inner bottom wall of the driven frame 703. One end of the first electric push rod 706 is fixedly installed with a moving rod 707 through a clamping block. Telescopic plates 708 are fixedly installed at both ends of the moving rod 707. A hook plate 709 is fixedly installed at the other end of the telescopic plate 708. A first spring 710 is arranged inside the telescopic plate 708. The hook plate 709 is adapted to the connecting column 705. Clamping rods are fixedly installed at both ends of the V-shaped rod 704. The two ends of the clamping rod are slidably connected to a fixed frame 710. First chutes are opened on both side surfaces of the fixed frame 710. The clamping rod is slidably connected inside the first chute. Sliding plates 711 are fixedly installed on the upper surface of every two fixed frames 710. A number of side chutes 712 are opened on the inner side wall of the driven frame 703. Fixed blocks 713 are fixedly installed on both side surfaces of the sliding plate 711. The fixed block 713 is slidably connected inside the side chute 712. The upper surface of the driven frame 703 is arranged in an open shape. A number of adjusting columns 714 are opened on the upper surface of the sliding plate 711. A bottom frame 715 is slidably connected to the outer surface of the adjusting column 714. A second chute is opened on the lower surface of the bottom frame 715. The adjusting column 714 is slidably connected inside the second chute. Combining modules 716 are fixedly installed on both sides of the lower surface of the mold 8. A number of side columns are fixedly installed on the side surface of the barrier block 9. A second connecting plate 717 is fixedly installed on the surface of the side column. A connecting frame 718 is fixedly installed on the side surface of the second connecting plate 717 through a column body. A second sliding block 719 is fixedly installed at the bottom end of the connecting frame 718. The second sliding block 719 is slidably connected inside the bottom frame 715. Grooves are opened on the lower surface of both the second sliding block 719 and the combining module 716. The groove is adapted to the adjusting column 714. Positioning plates are fixedly installed on the side surfaces of the mold 8. A positioning column 13 is fixedly installed on the side surface of one of the positioning plates.

[0043] In this embodiment: In the initial state, by starting the hydraulic cylinder 702, the first sliding block 701 at one end slides on the outer surface of the guide frame. The first sliding block 701 drives the driven frame 703 on the upper surface, the combined module 716, and the second sliding block 719 on one side to move synchronously, so that the upper die 8 and the barrier block 9 move synchronously, ensuring that the workpiece inside the blow molding can form the shape inside the die and guaranteeing the quality of blow molding. When it is necessary to separate the film directly from the workpiece of the barrier block 9, the staff starts the first electric push rod 706 inside to extend and drive the moving rod 707 to move. During the movement of the moving rod 707, it drives the telescopic plate 708 and the hook plate 709 on one side to move. The hook plate 709 clings to the outer surface of the connecting column 705 and squeezes it to move. The first spring inside extends and stretches, causing the connecting column 705 to drive the V-shaped rod 704 to rotate at the bottom. The rotation of the V-shaped rod 704 drives the latch at one end to slide on the side surface of the fixed frame 710, causing the fixed frame 710 on one side to drive the upper sliding plate 711 to slide upward, and the fixed frame 710 on the other side to drive the upper sliding plate 711 to slide downward. The sliding plate 711 on one side drives the upper adjusting column 714 to insert deep into the groove on the lower surface of the second sliding block 719, and the adjusting column 714 on the other side disengages from the groove inside the lower surface of the combined module 716. Then, by starting the hydraulic cylinder 702, the driven frame 703 slides, and drives the second connecting plate 717 to move through the connecting frame 717. The second connecting plate 717 drives the barrier block 9 to move through the side column. The two barrier blocks 9 move synchronously, but the workpiece inside the die 8 is in a fixed state. Thus, by sliding the barrier block 9, the film inside the workpiece is impacted and dropped, and then reset. The barrier block 9 is reset to its original position. Then, the first electric push rod 706 drives the moving rod 707 to reset, so that the V-shaped rod 704 returns to the horizontal state again. At this time, by starting the hydraulic cylinder 702, the die 8 and the two barrier blocks 9 on both sides slide synchronously, causing the workpiece and the waste to fall down.

[0044] Please refer specifically to Figures 1 to 10 , as a further solution of the present invention: A rectangular frame is provided on the outer surface of the extruder 2, and cylinders 14 are provided on both side surfaces of the rectangular frame. A sealing clamping plate 15 is provided at one end of the cylinder 14.

[0045] By starting the cylinder 14, the sealing clamping plate 15 is driven to move. The two sealing clamping plates 15 move towards the middle, clamping the bottom of the conveyed material to make the bottom in a sealed state.

[0046] The upper surface of the mold 8 is fixedly installed with a sealed clamping plate 16. The side surface of the sealed clamping plate 16 is provided with a number of arc-shaped protrusions and arc-shaped grooves. The arc-shaped protrusions and arc-shaped grooves on the surfaces of the two sealed clamping plates 16 are adapted to each other. The blowing system 11 includes a stretching solenoid valve, a high-pressure blowing valve, and a blowing air storage cylinder 1101. The top gate removing component 10 includes a fixed clamping ring 1001 fixedly installed on the outer surface of the blowing air storage cylinder 1101. The side surface of the fixed clamping ring 1001 is provided with a groove. A second spring 1002 is arranged inside the groove. One end of the second spring 1002 is fixedly installed with an arc-shaped block 1003. The outer side of the arc-shaped block 1003 is an arc-shaped surface. A gate removing groove is arranged on the inner side wall of the mold 8. A push plate 1004 is slidably connected inside the gate removing groove. Both sides of one side surface of the push plate 1004 are fixedly installed with push columns. One end of the two push columns is fixedly installed with a first connecting plate 1005. One side surface of the first connecting plate 1005 is rotatably connected with a push rod 1006 through a hinge. The other end of the push rod 1006 is rotatably connected with an L-shaped plate 1007 through a hinge. One end of the L-shaped plate 1007 is fixedly installed with a semi-arc-shaped clamping ring 1008. A telescopic column is fixedly installed on the lower surface of the L-shaped plate 1007. A return spring 1009 is fixedly installed inside the telescopic column.

[0047] In this embodiment: During the downward movement of the air storage cylinder 1101, the fixed clamping ring 1001 on its outer surface slides downward. When the arc-shaped block 1003 on the outer surface of the fixed clamping ring 1001 disengages from the inner side wall of the semi-arc-shaped clamping ring 1008, due to its arc-shaped surface, the arc-shaped block 1003 will contract into the inside of the groove and squeeze the second spring 1002 inside. After moving to the bottom, blow molding operation is carried out. After the blow molding is completed, during the contraction process, since the upper surface plane of the arc-shaped block 1003 contacts the lower surface of the semi-arc-shaped clamping ring 1008, the arc-shaped block 1003 drives the semi-arc-shaped clamping ring 1008 to move synchronously. Then, the semi-arc-shaped clamping ring 1008 drives the L-shaped plate 1007 at one end to move upward. The L-shaped plate 1007 drives the push rod 1006 on one side to move. The push rod 1006 drives the first connecting plate 1005 and the push column on one side to move. The push column drives the push plate 1004 at one end to move. The moving push plate 1004 pushes off the excess flash on the upper surface of the workpiece. Then, when the semi-arc-shaped clamping ring 1008 disengages from the upper surface of the arc-shaped block 1003, it is reset through the return spring 1009 inside the telescopic column.
