[0002] Scalding-proof packaging boxes are specially designed packaging containers used to hold high-temperature items, such as beverages and food. They can effectively prevent heat from being transferred to the outside and protect users from burns. Scalding-proof packaging box production molds are special molds used to produce scalding-proof packaging boxes.

[0003] In existing molds for producing heat-resistant packaging boxes, dust or particles can fall onto the boxes during the stamping process, causing appearance defects that prevent the boxes from entering the market. This results in a high scrap rate and increases production costs. Utility Model Content

[0004] The purpose of this utility model is to provide a heat-resistant packaging box production mold to solve the problem mentioned in the background art that in the existing heat-resistant packaging box production mold, dust or particles fall on the packaging box during the stamping process, causing appearance defects in the stamped packaging box, making it unusable in the market, resulting in a high scrap rate of packaging boxes and increasing production costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold for producing anti-scalding packaging boxes includes a base frame, a guide rod fixedly connected to the surface of the base frame, a top frame fixedly connected to the surface of the guide rod, a first cylinder fixedly connected to the surface of the top frame, a protective shell fixedly connected to the piston rod of the first cylinder, an upper mold fixedly connected to the surface of the protective shell, a protective base plate fixedly connected to the surface of the guide rod, a rotating rod rotatably connected to the surface of the base frame, an adjusting plate fixedly connected to the surface of the rotating rod, a second cylinder fixedly connected to the surface of the adjusting plate, a clamping plate fixedly connected to the piston rod of the second cylinder, a lower mold fixedly connected to the surface of the clamping plate, a first gear fixedly connected to the surface of the rotating rod, a servo motor fixedly connected to the lower surface of the base frame, and a second gear fixedly connected to the output shaft of the servo motor.

[0006] Preferably, the bottom of the protective shell is open, the upper mold is fixedly connected to the top inner side of the protective shell, and the protective shell slides and rises and falls on the surface of the guide rod by the piston rod of the first cylinder.

[0007] Preferably, the base frame supports the protective base plate via guide rods, and the inner surface of the protective outer shell slides on the outer side of the protective base plate.

[0008] Preferably, a rectangular locking hole is formed on the surface of the protective base plate, and the locking plate is raised and lowered on the base frame by the piston rod of the second cylinder, and the locking plate is engaged with the rectangular locking hole of the protective base plate.

[0009] Preferably, the adjusting plate rotates on the surface of the base frame via a rotating rod, and the second cylinder and the clamping plate rotate on the surface of the base frame following the rotating rod.

[0010] Preferably, the lower mold changes its tilt angle on the base frame by rotating the clamping plate.

[0011] Preferably, the second gear is driven to rotate by the output shaft of the servo motor, the first gear and the second gear mesh with each other, and the second gear drives the rotating rod to rotate on the base frame through the first gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This mold uses the piston rod of the second cylinder to drive the clamping plate to rise, causing the clamping plate to rise onto the rectangular clamping hole of the protective base plate. The first cylinder uses the piston rod to adjust the protective shell to slide and descend on the guide rod. The protective shell drives the upper mold to descend synchronously, and the bottom of the protective shell slides and descends on the protective base plate. This ensures that the upper and lower molds are always between the protective shell and the protective base plate during the stamping process of the packaging box, preventing dust particles from falling on the surface of the packaging box, thereby avoiding defects in the stamping of the packaging box, reducing the scrap rate of the packaging box, and saving the production cost of the packaging box.

[0014] 2. The mold drives the second gear to rotate via the output shaft of the servo motor. The electromagnetic brake of the servo motor locks the second gear after it rotates. The second gear drives the rotating rod to rotate via the first gear. The rotating rod drives the clamping plate to rotate via the adjusting plate. The clamping plate drives the lower mold to rotate the packaging box, thereby changing the picking angle of the packaging box, reducing the labor intensity when manually picking it out, and reducing the risk of damage to the packaging box during the picking process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A mold for producing heat-resistant packaging boxes includes a base frame 1, a guide rod 2 fixedly connected to the surface of the base frame 1, a top frame 3 fixedly connected to the surface of the guide rod 2, a first cylinder 4 fixedly connected to the surface of the top frame 3, a protective shell 5 fixedly connected to the piston rod of the first cylinder 4, an upper mold 6 fixedly connected to the surface of the protective shell 5, a protective base plate 7 fixedly connected to the surface of the guide rod 2, a rotating rod 8 rotatably connected to the surface of the base frame 1, an adjusting plate 9 fixedly connected to the surface of the rotating rod 8, a second cylinder 10 fixedly connected to the surface of the adjusting plate 9, a clamping plate 11 fixedly connected to the piston rod of the second cylinder 10, and a lower mold 12 fixedly connected to the surface of the clamping plate 11. A first gear 13 is fixedly connected to the surface of the base 8, and a servo motor 14 is fixedly connected to the lower surface of the base 1. A second gear 15 is fixedly connected to the output shaft of the servo motor 14. During the stamping process of the upper mold 6 and the lower mold 12, the production mold will keep the upper mold 6 and the lower mold 12 between the protective shell 5 and the protective base plate 7, thereby avoiding the presence of dust and particles on the packaging box, thus avoiding defects in the stamping of the packaging box, reducing the scrap rate of the packaging box, saving the production cost of the packaging box, and the lower mold 12 can adjust the angle of the packaging box by rotating after stamping, reducing the labor intensity when manually taking it out and reducing the risk of damage to the packaging box during the taking out process.

[0024] Furthermore, the bottom of the protective shell 5 is open, and the upper mold 6 is fixedly connected to the top of the inner side of the protective shell 5. The protective shell 5 slides and rises on the surface of the guide rod 2 through the piston rod of the first cylinder 4. During the rising and falling process, the upper mold 6 is adjusted to rise and fall, so that the upper mold 6 completes the stamping of the packaging box on the lower mold 12.

[0025] Furthermore, the base frame 1 supports the protective base plate 7 through the guide rod 2, the inner surface of the protective shell 5 slides on the outer side of the protective base plate 7, and the protective shell 5 always slides on the surface of the protective base plate 7, ensuring that the upper mold 6 is always between the protective shell 5 and the protective base plate 7 during the stamping process.

[0026] Furthermore, a rectangular locking hole is provided on the surface of the protective base plate 7. The locking plate 11 is raised and lowered on the base frame 1 by the piston rod of the second cylinder 10. The locking plate 11 is engaged with the rectangular locking hole of the protective base plate 7, thus sealing the rectangular locking hole of the protective base plate 7. At this time, the lower mold 12 is also located between the protective shell 5 and the protective base plate 7.

[0027] Furthermore, the adjusting plate 9 rotates on the surface of the base frame 1 via the rotating rod 8, and the second cylinder 10 and the clamping plate 11 follow the rotating rod 8 to rotate on the surface of the base frame 1. The adjusting plate 9 can only rotate when the clamping plate 11 is not on the rectangular clamping hole of the protective base plate 7.

[0028] Furthermore, the lower mold 12 changes its tilt angle on the base frame 1 by rotating the clamping plate 11. The change in the tilt angle of the lower mold 12 changes the picking angle of the packaging box. By optimizing the picking angle, the error of manual picking of the packaging box is reduced, and the efficiency of picking the packaging box is improved.

[0029] Furthermore, the second gear 15 is driven to rotate by the output shaft of the servo motor 14. The servo motor 14 is equipped with an electromagnetic brake, which can lock the angular position of the second gear 15 after it has rotated, so as to prevent the second gear 15 from shifting in position. The first gear 13 and the second gear 15 mesh with each other. The second gear 15 drives the rotating rod 8 to rotate on the base frame 1 through the first gear 13, thereby driving the adjusting plate 9 to rotate on the surface of the base frame 1.

[0030] Working principle: The piston rod of the second cylinder 10 drives the clamping plate 11 to rise, causing it to rise onto the rectangular clamping hole of the protective base plate 7. The first cylinder 4, through its piston rod, moves the protective shell 5 to slide and descend on the guide rod 2. The protective shell 5 drives the upper mold 6 to descend synchronously, and the bottom of the protective shell 5 slides and descends on the protective base plate 7. This ensures that the upper mold 6 and the lower mold 12 remain between the protective shell 5 and the protective base plate 7 during the stamping process of the packaging box, preventing dust particles from falling onto the surface of the packaging box, thus avoiding defects in the stamping process and reducing the packaging box's quality. The scrap rate is reduced, saving on the production cost of the packaging box. When the lower mold 12 descends below the bottom of the protective base plate 7, the servo motor 14 drives the second gear 15 to rotate through the output shaft. The electromagnetic brake of the servo motor 14 locks the second gear 15 after it rotates. The second gear 15 drives the rotating rod 8 to rotate through the first gear 13. The rotating rod 8 drives the clamping plate 11 to rotate through the adjusting plate 9. The clamping plate 11 drives the lower mold 12 to rotate the packaging box, thereby changing the picking angle of the packaging box, reducing the labor intensity when manually picking it out, and reducing the risk of damage to the packaging box during the picking process.
