Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of molds for carton forming and die-cutting machines, and more specifically, to a mold for forming U-shaped carton pads. Background Technology
[0002] As a primary packaging medium in modern commodity circulation, the forming process of cardboard boxes directly determines packaging efficiency and cost control. Currently, the commonly used cardboard box forming mold technology in the industry is mainly based on die-cutting principles, using customized metal dies to creasing and cutting corrugated cardboard. Depending on product specifications, manufacturers need to design and manufacture dedicated die-cutting molds for each cardboard box or related padding. This "one item, one mold" production model has persisted for decades, becoming a technological bottleneck restricting the industry's flexible development.
[0003] With the explosive growth of demand for customized packaging in e-commerce logistics, traditional mold technology is no longer able to meet the market requirements of "multiple specifications and short cycles." The industry urgently needs to develop a molding mold system that can adapt to the current market characteristics of "multiple specifications and short cycles" in e-commerce logistics. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of existing carton forming molds, which can only produce one mold for one item, and to provide a carton U-shaped pad forming mold that can adapt to the current market demand characteristics of "multiple specifications and short cycle" in e-commerce logistics.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A U-shaped cardboard pad forming mold is provided, including an outer mold frame, a driving mechanism, and a size adjustment mechanism. The size adjustment mechanism includes a fixed knife holder, a movable knife holder, and an adjusting block. The driving mechanism is drivenly connected to the movable knife holder, the fixed knife holder is fixedly connected to the outer mold frame, and the movable knife holder is slidably connected to the outer mold frame. The driving mechanism drives the movable knife holder away from or towards the fixed knife holder. The adjusting block is installed between the movable knife holder and the fixed knife holder and is slidably connected to both the movable and fixed knife holders.
[0007] In the operation of the above technical solution, when the mold is die-cut on the die-cutting machine, the distance between the fixed knife holder and the movable knife holder determines the width of the formed U-shaped carton pad, and the distance between the two adjusting blocks determines the length of the formed U-shaped carton pad. When it is necessary to change the size, several adjusting blocks of the same length are first installed on the side of the fixed knife holder. The operator operates the drive mechanism, which drives the movable knife holder to slide relative to the fixed knife holder in the outer mold frame, so that the side of the movable knife holder aligns with the other side of the adjusting block. After installation, several adjusting blocks can slide relative to the movable and fixed knife holders. The operator continues to manually slide the adjusting blocks so that the distance between the adjusting blocks meets the required size requirements. By changing the adjusting blocks of different lengths and adjusting the distance between the movable and fixed knife holders, different width sizes can be converted. By sliding the distance between the adjusting blocks, different length sizes can be converted, realizing the adaptive size conversion of the formed U-shaped carton pad, while avoiding the need to replace the entire mold when changing the size.
[0008] Furthermore, it also includes a slider. The two ends of the adjusting block are external splicing blocks, which are slidably connected to one side of the slider. The movable knife holder and the fixed knife holder are provided with guide rails on their facing sides, and the other side of the slider is slidably connected to the guide rail. The slider realizes the sliding connection between the adjusting block and the movable knife holder and the fixed knife holder. When it is necessary to change the length of the formed carton pad, the slider slides in the guide rail to realize the sliding of the adjusting block.
[0009] Furthermore, the adjusting block also includes several inner splicing blocks, which are detachably and fixedly connected to the outer splicing block, and the several inner splicing blocks are detachably and fixedly connected to each other. The adjusting block has a modular splicing design, which is composed of several inner splicing blocks and outer splicing blocks on both sides. When the width needs to be changed, it is only necessary to install and splice according to the requirements. At the same time, the outer splicing blocks and inner splicing blocks can also be modularly designed with different heights to achieve flexible changes in the height of the formed carton padding card, effectively adapting to the current market demand of "multiple specifications and short cycles" in e-commerce logistics.
[0010] Furthermore, the outer splicing block, the inner splicing block, and the slider are all provided with a plurality of grooves and protrusions. The outer splicing block and the slider are connected by engaging grooves and protrusions, and the inner splicing block and the outer splicing block are connected by engaging grooves and protrusions. A plurality of inner splicing blocks are connected to each other by engaging grooves and protrusions. After the grooves and protrusions are engaged, threaded holes can be provided on the outer splicing block, the inner splicing block, and the slider. After engagement, the threads can be threaded through the grooves and protrusions for fixation.
[0011] Furthermore, the size adjustment mechanism also includes a guide rod that passes through the fixed knife holder and the movable knife holder. Both ends of the guide rod are fixedly connected to the inner wall of the outer mold frame. The movable knife holder is slidably connected to the guide rod. The guide rod passes through the fixed knife holder and the movable knife holder, serving as a guide for the sliding of the movable knife holder, ensuring that the movable knife holder remains parallel to the fixed knife holder during the sliding process. This facilitates the installation of the adjustment block, and the cut cardboard pads will also achieve a horizontal and vertical straight appearance.
[0012] Furthermore, the two sides of the outer mold frame connected to the guide rod are called mold frame A, and the other two sides of the outer mold frame are called mold frames B. Mold frame A and mold frame B are detachably connected. The detachable design of the outer mold frame is to facilitate the assembly and replacement of the fixed and movable tool holders inside the outer frame. Under normal conditions, mold frame A is not opened. Only when the fixed tool holder is assembled for the first time or when the movable tool holder is damaged and needs to be replaced will one of the mold frames A be disassembled. The detachable connection between mold frame A and mold frame B can be a threaded connection or a snap-fit structure.
[0013] Furthermore, the driving mechanism includes a screw threadedly connected to the movable tool holder, one end of which is rotatably connected to the outer mold frame. The driving mechanism can also be a guide rail cylinder; however, compared to a cylinder, the manual driving method using a screw rod simplifies the mold structure and reduces mold costs because the workload of manual operation is not significant.
[0014] Furthermore, it also includes an operating unit, which is located outside the outer mold frame and fixedly connected to the screw. The operating unit is connected to the outside of the screw, which facilitates the operator to operate the screw to drive the movable tool holder. By manually operating the operating unit to rotate the screw, the movable tool holder is pushed to slide closer to and further away from the fixed tool holder, providing power support for width adjustment during mold processing.
[0015] Furthermore, a locking part is also provided outside the outer mold frame, which is used to lock the screw; the locking part fixes the rotatable screw to prevent the movable tool seat from shifting due to the screw loosening caused by the die-cutting vibration during the production process, thus affecting the processing accuracy.
[0016] Furthermore, it also includes a cutting tool. The fixed tool holder, the movable tool holder, and the adjusting block are all provided with tool mounting slots. The tool mounting slots are used to install the cutting tool. The cutting tool is installed on the fixed tool holder, the movable tool holder, and the adjusting block. After the entire mold is placed on the die-cutting machine, the die-cutting machine moves down to press the cardboard material, and the cutting tool performs the basic function of cutting.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. The drive mechanism is connected to the movable knife holder, the fixed knife holder is fixedly connected to the outer mold frame, and the movable knife holder is slidably connected to the outer mold frame. The drive mechanism drives the movable knife holder to move away from or closer to the fixed knife holder. The adjusting block is installed between the movable knife holder and the fixed knife holder and is slidably connected to both. By changing the adjusting blocks of different lengths and adjusting the distance between the movable and fixed knife holders, different width dimensions can be converted. By sliding the distance between the adjusting blocks, different length dimensions can be converted, realizing the adaptive size conversion of the U-shaped cardboard pad for the formed carton. At the same time, it avoids replacing the entire mold when the size needs to be changed, adapting to the current market demand of "multiple specifications and short cycles" in e-commerce logistics.
[0019] 2. The size adjustment mechanism includes a guide rod that passes through the fixed knife holder and the movable knife holder, guiding the sliding of the movable knife holder and helping the die-cut carton pads to achieve a horizontal and vertical straight appearance.

[0028] This embodiment is a first embodiment of a U-shaped cardboard pad forming mold, such as... Figures 1 to 3 As shown, the device includes an outer mold frame 100, a drive mechanism 200, and a size adjustment mechanism 300. The size adjustment mechanism 300 includes a fixed cutter holder 310, a movable cutter holder 320, and an adjustment block 330. The drive mechanism 200 is connected to the movable cutter holder 320 in a transmission manner. The fixed cutter holder 310 is fixedly connected to the outer mold frame 100. The movable cutter holder 320 is slidably connected to the outer mold frame 100. The drive mechanism 200 drives the movable cutter holder 320 away from or closer to the fixed cutter holder 310. The adjustment block 330 is installed between the movable cutter holder 320 and the fixed cutter holder 310 and is slidably connected to both the movable cutter holder 320 and the fixed cutter holder 310.
[0029] Specifically, it also includes a slider. The two ends of the adjusting block 330 are external splicing blocks 331. The external splicing blocks 331 are slidably connected to one side of the slider. The movable knife holder 320 and the fixed knife holder 310 are provided with guide rails on their facing sides. The other side of the slider is slidably connected to the guide rail. The slider realizes the sliding connection between the adjusting block 330 and the movable knife holder 320 and the fixed knife holder 310. When it is necessary to change the length of the formed carton pad, the slider slides in the guide rail to realize the sliding of the adjusting block 330.
[0030] Specifically, the adjusting block 330 also includes several inner splicing blocks 332, which are detachably and fixedly connected to the outer splicing blocks 331, and the several inner splicing blocks 332 are detachably and fixedly connected to each other. The adjusting block 330 is a modular splicing design, composed of several inner splicing blocks 332 and outer splicing blocks 331 on both sides. When the width needs to be changed, it is only necessary to install and splice according to the requirements. At the same time, the outer splicing blocks 331 and the inner splicing blocks 332 can also be modularly designed with different heights to achieve flexible changes in the height of the formed carton padding card, effectively adapting to the current market demand of "multiple specifications and short cycles" in e-commerce logistics.
[0031] Specifically, the outer splicing block 331, the inner splicing block 332, and the slider are all provided with a number of grooves 600 and protrusions 700. The outer splicing block 331 and the slider are connected by engaging grooves 600 and protrusions 700. The inner splicing block 332 and the outer splicing block 331 are connected by engaging grooves 600 and protrusions 700. Several inner splicing blocks 332 are connected to each other by engaging grooves 600 and protrusions 700. After the grooves 600 and protrusions 700 are engaged, threaded holes can be provided on the outer splicing block 331, the inner splicing block 332, and the slider. After engagement, the threads can be used to fix the blocks through the grooves 600 and protrusions 700.
[0032] Specifically, the size adjustment mechanism 300 also includes a guide rod 340, which passes through the fixed cutter holder 310 and the movable cutter holder 320. Both ends of the guide rod 340 are fixedly connected to the inner wall of the outer mold frame 100. The movable cutter holder 320 is slidably connected to the guide rod 340. The guide rod 340 passes through the fixed cutter holder 310 and the movable cutter holder 320, which serves as a guide for the sliding of the movable cutter holder 320, so that the movable cutter holder 320 always remains parallel to the fixed cutter holder 310 during the sliding process. This is beneficial for the installation of the adjustment block 330, and at the same time, the cut cardboard pads will also achieve a horizontal and vertical straight effect in appearance.
[0033] The working principle of a U-shaped cardboard pad forming mold in this embodiment is as follows:
[0034] Before the mold is installed into the die-cutting machine, select the corresponding number of inner splicing blocks 332 and outer splicing blocks 331 according to production requirements.

At the same time, operate the drive mechanism 200 to drive the movable knife holder 320. The movable knife holder 320 slides on the guide rod 340 so that the distance between the movable knife holder 320 and the fixed knife holder 310 matches the length of the adjusting block 330. Then, install several adjusting blocks 330 between the movable knife holder 320 and the fixed knife holder 310 through the sliding connection of the slider on the outer splicing block 331 and the slide rail. Finally, slide to adjust the spacing of each adjusting block 330. After completion, push the mold into the die-cutting machine to start production.
[0035] The beneficial effects of this embodiment are: different width dimensions can be converted by changing the adjustment blocks 330 of different lengths and adjusting the distance between the movable knife holder 320 and the fixed knife holder 310, and different length dimensions can be converted by sliding the distance between the adjustment blocks 330, so as to realize the adaptive size conversion of the U-shaped pad card of the formed carton, while avoiding the need to replace the entire mold when the size needs to be changed.
[0036] Example 2
[0037] This embodiment is a second embodiment of a U-shaped cardboard pad forming mold, such as... Figure 1 As shown, the difference from Embodiment 1 is as follows:
[0038] Specifically, the two sides of the outer mold frame 100 connected to the guide rod 340 are called A mold frame 110, and the other two sides of the outer mold frame 100 are called B mold frame 120. The A mold frame 110 and the B mold frame 120 are detachably connected. The detachable design of the outer mold frame 100 is to facilitate the assembly and replacement of the fixed tool holder 310 and the movable tool holder 320 inside the outer mold frame 100. Under normal conditions, the A mold frame 110 is not opened. Only when it is assembled for the first time or when the fixed tool holder 310 or the movable tool holder 320 is damaged and needs to be replaced will one of the A mold frames 110 be disassembled. The detachable connection between the A mold frame 110 and the B mold frame 120 can be a threaded connection or a snap-fit structure.
[0039] The working principle of a U-shaped cardboard pad forming mold in this embodiment is as follows:
[0040] When assembling or repairing / replacing for the first time, simply disconnect the detachable connection between mold frame A 110 and mold frame B 120, and then remove and replace the fixed tool holder 310, movable tool holder 320, adjusting block 330, and guide rod 340 one by one.
[0041] The beneficial effects of this embodiment are: the detachable mold frame design improves the flexibility of the entire mold assembly and disassembly, making it easier for workers to operate.
[0042] Example 3
[0043] This embodiment is a third embodiment of a U-shaped cardboard pad forming mold, such as... Figure 1 As shown, the difference from Embodiment 1 is as follows:
[0044] Specifically, the drive mechanism 200 includes a screw 210 threadedly connected to the movable tool holder 320, with one end of the screw 210 rotatably connected to the outer mold frame 100. The drive mechanism 200 can also be a guide rail cylinder; however, compared to a cylinder, since the workload of manual operation is not large, the manual drive form of the screw rod can simplify the mold structure and reduce mold costs.
[0045] Specifically, it also includes an operating unit 220, which is located outside the outer mold frame 100 and fixedly connected to the screw 210. The screw 210 is connected to the operating unit 220, which makes it easy for the worker to operate the screw 210 to drive the movable tool holder 320. By manually operating the operating unit 220 to rotate the screw 210, the movable tool holder 320 is pushed to achieve sliding action relative to the fixed tool holder 310, providing power support for width adjustment during mold processing.
[0046] Specifically, a locking part 130 is also provided outside the outer mold frame 100. The locking part 130 is used to lock the screw 210. The locking part 130 fixes the rotatable screw 210 to prevent the screw 210 from loosening due to die-cutting vibration during the production process, which would cause the movable tool holder 320 to shift and affect the processing accuracy.
[0047] Specifically, it also includes a cutting blade 400. The fixed blade holder 310, the movable blade holder 320, and the adjusting block 330 are all provided with blade mounting slots 500. The blade mounting slots 500 are used to install the cutting blade 400. The cutting blade 400 is installed on the fixed blade holder 310, the movable blade holder 320, and the adjusting block 330. After the entire mold is placed on the die-cutting machine, the die-cutting machine moves down to press the cardboard material, and the cutting blade 400 then performs the basic function of cutting.
[0048] The working principle of a U-shaped cardboard pad forming mold in this embodiment is as follows:
[0049] The drive mechanism 200 is operated manually. During operation, the operator rotates the operating part 220 to rotate the screw 210. The screw 210 drives the movable cutter holder 320 to slide on the guide rod 340. After the sliding is adjusted to the distance required for production, the operating locking part 130 locks the screw 210. Finally, the cutting cutter 400 is installed on the cutter mounting seam 500, and die cutting can be performed.
[0050] The beneficial effects of this embodiment are: the drive mechanism 200 adopts the form of screw 210 to cooperate with the operating part 220 and the locking part 130, which effectively simplifies the mold structure and reduces the mold cost under the premise of low manual operation load.
[0051] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
