At the same time, the dust that may exist in the forming fixture 8 can be cleaned in time, thereby improving the forming rate of the forming machine frame 1.

[0042] Embodiment 2, on the basis of embodiment 1, the vertical cross-section of the forming tube rack 6 is in the shape of a "7", and a receiving groove 33 is provided on the inner wall of one side of the forming tube rack 6, and a movable groove 41 is provided on the inner walls of both sides of the storing groove 33. The inner walls of the movable grooves 41 on both sides are slidably connected with the same movable block 42, and the bottom outer wall of the movable block 42 is fixedly connected with a guide piece 40, and the guide piece 40 is in an arc shape. The inner wall of the storing groove 33 is fixedly connected with a rotating roller 44, and the outer wall of the rotating roller 44 is movably fitted with the outer wall of the guide piece 40. A folding plate 34 is provided at the bottom of the storing groove 33, and a spring hinge 35 is fixedly connected to the outer wall of one end of the folding plate 34. The spring hinge 35 is away from the outer wall of one end of the folding plate 34. A folding plate 2 36 is fixedly hinged, and the outer walls of the folding plate 1 34 and the folding plate 2 36 at one end away from the spring hinge 35 are fixedly connected with a connecting hinge. The folding plate 1 34 is hinged to the bottom inner wall of the storage groove 33 through the connecting hinge, and the folding plate 2 36 is hinged to the bottom inner wall of the guide plate 40 through the connecting hinge. A winding cavity 37 is provided inside the forming tube rack 6, and a guide groove 38 connected to the winding cavity 37 is provided on one side inner wall of the storage groove 33.

[0043] In the present invention, the guide piece 40 is a metal sheet with a certain flexibility and resilience. Its original shape is an arc shape, rather than a straight plate that is compressed into an arc shape. By splicing the two guide pieces 40 together, a group of wind flow guide channels that match the curvature of the inner wall of the forming fixture 8 are formed, which compresses the wind flow and can be blown in a streamlined manner along the entire process of the inner wall of the forming fixture 8, thereby improving the dust blowing efficiency and avoiding air turbulence on the inner wall of the forming fixture 8. When the two forming tube racks 6 converge toward the forming machine frame 1, the storage rod 22 will rotate, and the tension belt 39 will be gradually wound into the winding chamber 37 by the rotation. At this time, the spring hinge 35 is pulled by the spring hinge 35, and because one end of the folding plate 2 36 is pressed by the guide piece 40, the wind flow is compressed. The folding plate 1 34 and the folding plate 2 36 are folded into the storage groove 33 with the spring hinge 35 as the axis, and the guide piece 40 is against the outside of the storage groove 33. The superimposed width of the guide piece 40, the folding plate 2 36 and the folding plate 1 34 is the same width as the storage groove 33. At this time, because the angle of the guide piece 40 changes, the arc angle formed by the movable groove 41 is within the bending value of the guide piece 40. At the same time, it is affected by the lifting of the bottom folding plate 2 36 and the pressure of the forming tube rack 6 on the storage groove 33 when the dustproof plate 12 moves upward. The guide piece 40 will slide into the movable groove 41. At this point, the dustproof plate 12 is completely flush with the working chamber 9. When the two forming tube racks 6 are completely aggregated, the two opposing dustproof plates 12 will press each other and move into the working chamber 9 to complete the storage.

The outer walls of both sides of the forming pipe rack 6 are provided with annular grooves 43. The outer walls of both ends of the storage rod 22 pass through the inner wall of the winding chamber 37 and are connected with the annular groove 43. The storage rod 22 is located in the annular groove 43 and is fixedly connected to the connecting gear 23. The outer wall of the connecting gear 23 is meshed with the outer wall of the connecting rack 21. A working bin 24 is provided inside one side of the forming pipe rack 6. The outer wall of the rotating shaft 7 is located in the working bin 24 and is fixedly connected with two sprockets 25. The upper and lower ends of the forming pipe rack 6 are provided with mounting bins 32. Both ends of the inner wall of the mounting bin 32 are rotatably connected to a rotating rod 28 connected to the working bin 24. The outer wall of one end of the rotating rod 28 is fixedly connected to a sprocket 27. The two sprockets 27 are respectively meshed with the outer walls of the sprocket 1 25 and are connected with a belt 26. The outer wall of the end of the rotating rod 28 away from the sprocket 27 is fixedly connected to a bevel gear 1 30, and the bottom inner wall of the mounting bin 32 is rotatably connected to the bevel gear 2 31 The bevel gear 2 31 is meshed with the bevel gear 1 30, and the inner wall of the working chamber 9 is rotatably connected with a threaded limiting column 29.

[0045] In the present invention, when the two forming pipe racks 6 converge toward the position of the forming machine frame 1, the screw stepper motor 4 is started to rotate the threaded screw 5, and the rotation of the two threaded screws 5 will drive the sprocket 1 25 to rotate synchronously in the working chamber 24. Further, the sprocket 1 25 drives the two bevel gears to rotate through the belt 26 and the rotating rod 28, and the bevel gear 2 31 further drives the threaded limiting column 29 to rotate. At this time, the dustproof plate 12 is in a closed state on the inner wall of the forming fixture 8, and the semi-threaded connecting cavity 46 is threadedly engaged with the threaded limiting column 29. The rotation of the threaded limiting column 29 drives the dustproof plate 12 to move vertically upward. During the upward movement, the folding plate 34 will engage with the connecting rack 21 to drive the storage rod 22 to rotate synchronously. The rotation of the storage rod 22 will simultaneously press the guide plate 40 into the storage groove 33 until the dustproof plate 12 is completely moved to the same level as the working chamber 9.

At this time, the two formed pipe racks 6 are completely aggregated, and the two opposite dustproof plates 12 will press against each other to force the pressing plate 19 to slide in the slide groove 17. The threaded limit column 29 will also disengage from the semi-threaded connecting cavity 46 and enter the strip-shaped connecting cavity 45, so that the pressing plate 19 is completely stored in the working chamber 9.

[0046] The working principle and use process of the present invention: In the present invention, after the driving fixture 49 clamps the molding machine frame 1 in the molten state, the driving motor 50 is started to drive the mounting plate 48 to move horizontally to move the molding machine frame 1 to the center position of the two molding pipe racks 6. At the same time, the screw stepper motor 4 is started to extend and retract the threaded screw 5 to drive the two molding pipe racks 6 to move in the center and fit on the outer wall of the molding machine frame 1 to press and form the molding machine frame 1. After the molding machine frame 1 is completely shaped, the screw stepper motor 4 drives the threaded screw 5 to rotate, so that the two molding pipe racks 6 move back and away from the outer wall of the molding machine frame 1. While moving back, the two dustproof plates 12 slide out of the working chamber 9 and move up and down to cover the inner wall of the molding fixture 8 to avoid The impure air in the factory adheres to the inner wall of the forming fixture 8, and the air compressor 14 is started to generate air pressure, and the air flow is gradually transmitted to the forming fixture 8 through the ventilation main pipe 10, the diverter valve pipe 11 and the air flow duct 13, and the inner wall of the forming fixture 8 is blown to blow off the dust impurities that may be attached to the forming fixture 8 and discharge them into the collection box 15 with the air flow. In the present invention, the ventilation end of the air compressor 14 is equipped with a dust filter, which is a conventional device already available on the market. The unit workers perform regular inspections and cleanings, and the present invention will not go into details. Through this device, the exposure of the forming fixture 8 to the factory air before processing can be reduced to avoid dust adhesion. At the same time, the dust that may exist in the forming fixture 8 can be cleaned in time, thereby improving the forming rate of the forming machine frame 1. In the embodiment, the guide piece 40 is a metal sheet with a certain flexibility and resilience. Its original shape is an arc shape, and it is not a straight plate that is compressed into an arc shape. Through the mutual splicing of the two guide pieces 40, a group of wind flow guide channels that match the curvature of the inner wall of the forming fixture 8 are formed, which compresses the wind flow and can be streamlined to fit the inner wall of the forming fixture 8 throughout the process, thereby improving the dust blowing efficiency and avoiding air turbulence on the inner wall of the forming fixture 8. When the two forming pipe racks 6 converge toward the position of the forming machine frame 1, the storage rod 22 will rotate, and the tension belt 39 will be gradually wound into the winding chamber 37 by rotation. At this time, the spring hinge 35 is pulled by the spring hinge 35, and because one end of the folding plate 2 36 is pressed by the guide piece 40, the folding plate 1 34 and the folding plate 2 36 are elastically moved. The spring hinge 35 is axially folded into the receiving groove 33, and the guide piece 40 is against the outside of the receiving groove 33. The superimposed width of the guide piece 40, the folding plate 2 36 and the folding plate 1 34 is the same width as the receiving groove 33. At this time, because the angle of the guide piece 40 changes, the arc angle formed by the movable groove 41 is within the bending value of the guide piece 40. At the same time, it is affected by the lifting of the bottom folding plate 2 36 and the pressure of the forming pipe frame 6 on the receiving groove 33 when the dust plate 12 moves upward. The guide piece 40 will slide into the movable groove 41. At this point, the dust plate 12 is completely flush with the working chamber 9. When the two forming pipe racks 6 are fully assembled, the two opposing dust plates 12 will press each other and move into the working chamber 9 to complete the storage. In the present invention, when the two forming pipe racks 6 are assembled toward the position of the forming machine frame 1,The screw stepper motor 4 is started to rotate the screw rod 5. The rotation of the two screw rods 5 will drive the sprocket 1 25 to rotate synchronously in the working chamber 24. Further, the sprocket 1 25 drives the two bevel gears to rotate through the belt 26 and the rotating rod 28. The bevel gear 2 31 further drives the threaded limit column 29 to rotate. At this time, the dustproof plate 12 is in a closed state on the inner wall of the forming fixture 8. The semi-threaded connecting cavity 46 will be threadedly engaged with the threaded limit column 29. The rotation of the threaded limit column 29 drives the dustproof plate 12 to move vertically upward. During the upward movement, the folding plate 13 4 will engage with the connecting rack 21 and drive the storage rod 22 to rotate synchronously. The rotation of the storage rod 22 will simultaneously press the guide piece 40 into the storage groove 33 until the dust plate 12 is completely moved to the same level as the working chamber 9. The pressure plate 19 will completely press against one side inner wall of the dust plate 12. At this time, the two formed pipe racks 6 are completely assembled. The two opposing dust plates 12 will press against each other to force the pressure plate 19 to slide in the slide groove 17. The threaded limit column 29 will also disengage from the semi-threaded connecting cavity 46 and enter the strip-shaped connecting cavity 45, thereby completely storing the pressure plate 19 in the working chamber 9.
