Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to an integrated stamping die for a corrugated cardboard box handle hole. Background Technology

[0002] The integrated stamping die for corrugated cardboard box handle holes is a mold equipment specifically designed for forming handle holes in corrugated cardboard boxes. This die integrates the stamping and forming process of the handle hole into the same mold structure. By using the cooperation of the upper and lower dies, the corrugated cardboard is stamped in one go under the action of a press to complete the cutting of the handle hole.

[0003] The integrated stamping die for corrugated cardboard box handle holes forms the handle holes through the precise cooperation of the upper and lower dies. The corrugated cardboard is placed on the positioning device of the lower die to ensure accurate board position. Then, the press drives the upper die downward, and the punch first cooperates with the cutting edge of the die to cut the cardboard to form the handle hole.

[0004] In existing technologies, some integrated stamping dies for corrugated cardboard box handle holes suffer from mismatches between the die and the cardboard box due to the different cardboard sizes of different types of boxes. The die uses a fixed block and positioning pin structure, which can only match cardboard of a specific size, resulting in a mismatch between the die and the box positioning and affecting stamping efficiency. Therefore, an integrated stamping die for corrugated cardboard box handle holes is proposed to solve the above problems. Utility Model Content

A limit plate is fixedly connected to the outside of the sliding shaft.

[0010] As a further description of the above technical solution:

[0011] The drive assembly includes a cylinder, which is externally fixedly connected to the inside of the fixed block. The drive end of the cylinder is fixedly connected to a connecting shaft, and the rear end of the connecting shaft is fixedly connected to the front end of one of the sliding plates.

[0012] As a further description of the above technical solution:

[0013] The bottom of the two positioning plates is slidably connected to the top of the workbench, and the outside of the two sliding rods is slidably connected to the inside of the two rotating plates respectively;

[0014] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, a starting cylinder drives a connecting shaft to push one of the sliding plates to slide. The sliding of one of the sliding plates pushes a rotating plate to rotate. The rotating plate drives a sliding rod to rotate through a rotating shaft. At the same time, the rotating shaft drives the rotating plate and the sliding rod to slide under the limit of the sliding groove. This causes the sliding rod to drive the other sliding plate to slide, thus forming a relative sliding between the two sliding plates. Meanwhile, the two sliding plates drive multiple positioning plates to slide through multiple fixed shafts, thereby fixing cartons of different sizes and improving the stamping efficiency of the stamping die.

[0024] 2. In this utility model, by pressing the sliding column, the sliding column drives the sliding block to squeeze the sliding shaft through the baffle, thereby causing the sliding shaft to disengage from the convex module, thus disassembling the fixed frame from the convex module. Then, by pushing the convex module into the interior of the fixed frame, the convex module squeezes the sliding shaft, and the sliding shaft drives the limiting plate to squeeze the second spring, causing the second spring to deform. When the convex module and the fixed frame are engaged, the second spring returns to its original position, so that the sliding shaft tightly locks the convex module, thereby completing the fixation of the convex module by the fixed frame, which facilitates the replacement of the convex module.

[0031] 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of an integrated stamping mold for corrugated cardboard box handle holes, including a workbench 1, which provides basic support and improves the stability of the stamping mold. A fixing block 2 is fixedly connected to the front end of the workbench 1, providing support for the fixing block 2 and improving its load-bearing capacity. A support frame 3 is fixedly connected to the top of the workbench 1, providing fixation for the support frame 3 and improving its stability. A drive assembly is fixedly connected inside the fixing block 2, providing fixation for the drive assembly and preventing vibration during operation. The drive assembly includes a cylinder 4, which is externally fixedly connected inside the fixing block 2, providing fixation for the cylinder 4 and improving its stability during operation, preventing vibration. A connecting shaft 5 is fixedly connected to the drive end of the cylinder 4, providing driving force for the movement of the connecting shaft 5 by activating the cylinder 4.

[0033] The workbench 1 has two sliding plates 6 internally connected. The rear end of a connecting shaft 5 is fixedly connected to the front end of one of the sliding plates 6. The movement of the connecting shaft 5 drives one of the sliding plates 6 to slide inside the fixed block 2. Two rotating plates 7 are rotatably connected internally to one of the sliding plates 6. The sliding plate 6 connects to the two rotating plates 7 via a shaft, and its movement drives the two rotating plates 7 to rotate. The two rotating plates 7 are externally slidably connected inside the workbench 1, which provides guidance for the sliding of the two rotating plates 7 and improves their sliding stability. Fixed shafts 8 are fixedly connected to the top of each of the two sliding plates 6. Multiple fixed shafts 8 are externally slidably connected inside the workbench 1, which has slide rails. The sliding of the sliding plates 6 drives the multiple fixed shafts 8 to slide within the workbench 1. Two positioning plates 9 are fixedly connected internally to the two fixed shafts 8. The positioning plates 9 are used to fix the position of the carton, and their movement is driven by the sliding of the fixed shafts 8. The bottom of the two positioning plates 9 are slidably connected to the top of the worktable 1, and the worktable 1 provides support for the two positioning plates 9, thereby improving the sliding stability of the two positioning plates 9.

[0034] Two sliding rods 10 are rotatably connected inside another sliding plate 6. The two sliding rods 10 are slidably connected to the interiors of two rotating plates 7. Rotation of the two rotating plates 7 drives the two sliding rods 10 to rotate, which in turn drives the other sliding plate 6 to slide within the worktable 1. Rotating shafts 11 are rotatably connected inside each of the two rotating plates 7. The two rotating shafts 11 are rotatably connected to the interiors of the two sliding rods 10, providing rotational support for the rotating plates 7 and the two sliding rods 10, thus improving their rotational stability. Two sliding grooves 12 are formed inside the worktable 1. The two rotating shafts 11 are slidably connected to the interiors of the two sliding grooves 12, providing guidance for the two rotating shafts 11. The two rotating shafts 11 slide relative to each other, driving the two rotating plates 7. A recessed module 13 is fixedly connected inside the worktable 1, providing fixation and improving its operational stability.

[0035] Reference Figure 1 , Figure 3 and Figure 4 A second cylinder 14 is fixedly connected to the top of the support frame 3, providing stability for the operation of the second cylinder 14. A fixed frame 15 is fixedly connected to the drive end of the second cylinder 14, providing a drive source for the fixed frame 15 by starting the second cylinder 14. A protruding module 16 is slidably connected inside the fixed frame 15, and a slide rail is provided inside the fixed frame 15 to guide the sliding of the protruding module 16. Multiple sliding blocks 17 are slidably connected inside the fixed frame 15, providing sliding support for the multiple sliding blocks 17 and improving the sliding stability of the sliding blocks 17. Two baffles 18 are slidably connected inside the fixed frame 15, with their left and right ends fixedly connected to the adjacent ends of the two sliding blocks 17 respectively. The fixed frame 15 guides the sliding of the baffles 18, causing the two sliding blocks 17 to slide. A spring 19 is fixedly connected to the bottom of the baffle 18. The sliding of the baffle 18 compresses the spring 19, causing the spring 19 to deform. The return of the spring 19 causes the baffle 18 to return to its original position.

[0036] The fixed frame 15 has two sliding posts 20 internally connected, providing guidance and stability for the sliding posts 20. The bottoms of the two sliding posts 20 are fixedly connected to the tops of two baffles 18, and the sliding of the sliding posts 20 drives the baffles 18 to slide. The fixed frame 15 also has multiple sliding shafts 21 internally connected, which engage with and fix the convex module 16. A second spring 22 is sleeved on the outside of each sliding shaft 21, ensuring even force distribution and preventing deformation. Limiting plates 23 are fixedly connected to the outside of each sliding shaft 21, and these limiting plates 23 are slidably connected inside the fixed frame 15. The fixed frame 15 has internal slide rails, allowing the limiting plates 23 to slide within the fixed frame 15 as the sliding of the sliding shafts 21 causes them to slide. The near ends of the two springs 22 are fixedly connected to the far ends of the two limiting plates 23 respectively. The sliding of the limiting plates 23 applies pressure to the springs 22, causing the springs 22 to deform.

[0037] Working principle: The connecting shaft 5 is displaced by starting cylinder 4, which in turn pushes one of the sliding plates 6 to slide. The sliding plate 6 drives two rotating plates 7 to rotate via shaft. The two rotating plates 7 drive two sliding rods 10 to rotate via two rotating shafts 11. At the same time, the rotating shafts 11 slide inside the slide groove 12, which in turn drives the two rotating plates 7 and the two rotating shafts 11 to slide. This causes the two sliding rods 10 to drive the other sliding plate 6 to slide. Simultaneously, the sliding of the two sliding plates 6 drives multiple fixed shafts 8 to slide relative to each other, which in turn drives multiple positioning plates 9 to slide, thereby fixing cartons of different specifications. Then, starting cylinder 14 drives the fixed frame 15 to drive the convex module 16 to impact the concave module 13, thereby completing the formation of the handle hole.

[0038] By pressing the two sliding posts 20, the sliding posts 20 press against the baffle 18, which in turn press against the two springs 19. At the same time, the two baffles 18 drive multiple sliding blocks 17 to press against the spring 22, causing the spring 22 to disengage from the inside of the convex module 16. At this time, the spring 19 drives the sliding posts 20 to reset through the baffle 18, and the fixed frame 15 separates from the convex module 16. By pushing the convex module 16 into the inside of the fixed frame 15, the convex module 16 presses against multiple sliding shafts 21 and engages with the sliding shafts 21. At the same time, the sliding shafts 21 press against the spring 22 through the limiting plate 23, causing the spring 22 to deform. When the spring 22 resets, it drives the sliding shafts 21 to engage with the convex module 16, thus completing the fixation of the convex module 16 by the fixed frame 15.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
