Description

Technical Field

[0001] This utility model relates to the field of molds, specifically an integrated top ear box-separating and waste-clearing mold that allows for quick mold changes. Background Technology

[0002] In the production of cardboard box packaging, die-cutting, waste removal, and forming are key processes. Traditional molds typically consist of multiple independent parts such as a die-cutting plate, a waste removal plate, and a bottom mold, which have the following disadvantages: When producing paper boxes of different specifications, it is necessary to replace the entire set of molds or multiple parts of them, which is cumbersome, requires high positioning accuracy, and takes a long time to change molds, thus affecting production efficiency. Functions such as die-cutting, waste removal, and top lugs (for easy box removal) are often implemented by different components, resulting in a fragmented structure and poor coordination. Therefore, in response to the above problems, an integrated top ear box separating and waste removal mold with quick mold change capability is proposed. Utility Model Content

[0003] To overcome the shortcomings of existing technology, when producing paper boxes of different specifications, it is necessary to replace the entire set of molds or multiple parts of them, which is cumbersome, requires high positioning accuracy, and has a long mold change time, thus affecting production efficiency. Die-cutting, waste removal, and top lugs (for easy box removal) are often performed by different components, resulting in a dispersed structure and poor coordination. This utility model proposes an integrated top lug box-separating and waste removal mold that can be quickly changed.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an integrated top ear box separation and waste removal mold with quick mold change, including an upper mold base, a die-cutting and waste removal integrated module and a lower mold base arranged sequentially from top to bottom; the upper end of the lower mold base is provided with a quick positioning and locking mechanism, and the die-cutting and waste removal integrated module is detachably installed on the lower mold base through the quick positioning and locking mechanism; The quick positioning and locking mechanism includes a positioning pin, which is fixedly connected to the upper end of the lower die base. A quick clamp is fixedly connected to the upper end of the lower die base. The bottom surface of the die-cutting and waste-removing integrated module is provided with a positioning hole that cooperates with the positioning pin. The top surface of the die-cutting and waste-removing integrated module is provided with a locking groove that cooperates with the locking head of the quick clamp. Each time a module is replaced, simply align the positioning hole on the module with the positioning pin on the lower mold base to achieve quick and accurate positioning. This method avoids the tedious process of repeatedly adjusting the alignment manually and the possible errors that may occur in the traditional method, ensuring the repeatability of the positioning accuracy of the mold each time it is installed, thereby guaranteeing the quality stability of product die-cutting and forming. The die-cutting and waste removal integrated module includes a die-cutting plate, a waste removal plate, and a top and bottom plate that are stacked and fixedly connected from top to bottom.

[0005] By integrating die-cutting, waste removal, and top ear functions into a complete die-cutting and waste removal integrated module and fixing it with a quick positioning and locking mechanism (positioning pin + quick clamp), overall modular quick changeover is achieved. When changing products, there is no need to disassemble, align, and install individual die-cutting plates, waste removal plates, and bottom molds one by one. Simply release the quick clamps to lift the entire integrated module away, then lift and lock the new integrated module. This greatly simplifies the operation process, significantly shortens the mold changeover time, and improves the flexibility and production efficiency of the production line. It is especially suitable for small-batch, multi-variety production modes.

[0006] Preferably, the waste removal plate has a through-hole for the waste material area generated after die-cutting, and a through-hole for the box forming area is provided on the waste removal plate. The size of the through-hole matches the outline of the box.

[0007] Preferably, the top ear base plate is provided with a plurality of top ear assemblies at the positions corresponding to the sub-box through holes; the top ear assembly includes a top rod and a return spring sleeved outside the top rod, the upper end of the top rod extends out of the sub-box through holes and can move up and down relative to the sub-box through holes, the top ear base plate is embedded with a guide sleeve, the top rod is slidably disposed in the guide sleeve, one end of the return spring is fixedly connected to the inside of the guide sleeve, and the other end is fixedly connected to the lower end of the top rod.

[0008] Preferably, a clearance groove is provided on the lower mold base corresponding to the lower part of the top ear assembly.

[0009] Preferably, the die-cutting plate, the waste removal plate, and the top and bottom ear plates are fixedly connected into a single module by connecting bolts that pass through the three.

[0010] Preferably, a stamping template is fixedly connected to the lower end of the upper die base, and a waste removal punch is fixed to the lower end of the upper die base. The position of the waste removal punch corresponds vertically to the position of the waste removal hole.

[0011] Preferably, the side walls of the die-cutting plate, the waste removal plate, and the top and bottom plates are all fixedly connected with lifting lugs.

[0012] The advantages of this utility model are: 1. This utility model integrates die-cutting, waste removal, and top ear functions into a complete die-cutting and waste removal integrated module, and uses a quick positioning and locking mechanism (positioning pin + quick clamp) for fixation, realizing overall modular quick change. When changing products, there is no need to disassemble, align, and install individual die-cutting plates, waste removal plates, and bottom molds one by one. Simply loosen the quick clamps to lift the entire integrated module away, and then lift and lock the new integrated module. This greatly simplifies the operation process, significantly shortens the mold change time, and improves the flexibility and production efficiency of the production line. It is especially suitable for small-batch, multi-variety production modes. 2. Each time the module is replaced, the positioning hole on the module is aligned with the positioning pin of the lower mold base and then lowered to achieve quick and accurate positioning. This method avoids the tedious process of repeated manual adjustment and possible errors in the traditional method, ensuring the repeatability of positioning accuracy of the mold each time it is installed, thereby ensuring the quality stability of product die cutting and forming. 3. The three-layer structure of die-cutting plate, waste removal plate, and top ear bottom plate is solidified into an integral module by connecting bolts. This breaks the pattern of traditional molds where the functional components are scattered and have poor coordination. Within a compact module, the entire process of die-cutting, waste removal, and ejecting the carton is completed in sequence. This integrated design makes the operation more continuous and reliable, reduces failures caused by poor coordination of multiple independent components, and improves the stability of equipment operation and the first-time molding qualification rate of products.

Detailed Implementation

[0016] 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 scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. This application discloses an integrated top ear box-separating and waste-clearing mold with quick mold change capability. (Refer to...) Figures 1-6 An integrated top ear box separation and waste removal mold with quick mold change capability includes an upper mold base 1, a die-cutting and waste removal integrated module 2 and a lower mold base 3 arranged sequentially from top to bottom; the upper end of the lower mold base 3 is provided with a quick positioning and locking mechanism 4, and the die-cutting and waste removal integrated module 2 is detachably installed on the lower mold base 3 through the quick positioning and locking mechanism 4. The quick positioning and locking mechanism 4 includes a positioning pin 401, which is fixedly connected to the upper end of the lower die base 3. A quick clamp 402 is fixedly connected to the upper end of the lower die base 3. The bottom surface of the die-cutting and waste-removing integrated module 2 is provided with a positioning hole 403 that cooperates with the positioning pin 401. The top surface of the die-cutting and waste-removing integrated module 2 is provided with a locking groove 404 that cooperates with the locking head of the quick clamp 402. Each time a module is replaced, simply align the positioning hole 403 on the module with the positioning pin 401 on the lower mold base 3 and place it down to achieve quick and accurate positioning. This method avoids the tedious process of repeatedly adjusting the alignment manually and the possible errors in the traditional method, ensuring the repeatability of the positioning accuracy of the mold each time it is installed, thereby guaranteeing the quality stability of product die cutting and forming. The die-cutting and waste removal integrated module 2 includes a die-cutting plate 201, a waste removal plate 202, and a top and bottom plate 203 that are stacked and fixedly connected from top to bottom.

[0018] By integrating die-cutting, waste removal, and top ear functions into a complete die-cutting and waste removal integrated module 2, and fixing it with a quick positioning and locking mechanism 4 (positioning pin 401 + quick clamp 402), overall modular quick change is achieved. When changing products, there is no need to disassemble, align, and install individual components such as the die-cutting plate 201, waste removal plate 202, and bottom mold one by one. Simply loosen the quick clamp 402 to lift the entire integrated module away, and then lift and lock the new integrated module. This greatly simplifies the operation process, significantly shortens the mold change time, and improves the flexibility and production efficiency of the production line. It is especially suitable for small-batch, multi-variety production modes.

[0019] Reference Figures 1-6 The waste removal board 202 has a through-hole 2021 for the waste area generated after die cutting, and a through-hole 2022 for the box forming area. The size of the through-hole 2022 matches the outline of the box.

[0020] The waste removal plate 202 has a through-hole 2021 for full waste removal, which works in conjunction with the waste removal punch 102 of the upper die to remove all waste from non-product areas in one go and over a large area (i.e., full waste removal). Compared with traditional manual or partial waste removal, this method is extremely efficient and the waste removal is thorough and clean, which provides convenience for subsequent automatic waste collection or automated production and further improves the overall production rhythm. The 2022 through-hole design allows individual die-cut cartons to exist independently in their respective holes, achieving natural separation.

[0021] Reference Figures 1-6 Multiple top ear assemblies 2031 are provided on the top ear base plate 203 at positions corresponding to the sub-box through hole 2022. The top ear assembly 2031 includes a top rod 20311 and a return spring 20312 sleeved outside the top rod 20311. The upper end of the top rod 20311 extends out of the sub-box through hole 2022 and can move up and down relative to the sub-box through hole 2022. A guide sleeve 20313 is embedded in the top ear base plate 203. The top rod 20311 is slidably disposed in the guide sleeve 20313. One end of the return spring 20312 is fixedly connected to the inside of the guide sleeve 20313, and the other end is fixedly connected to the lower end of the top rod 20311.

[0022] Under the action of the return spring 20312, the upper end of the top ear assembly 2031 is pressed down during die cutting. After die cutting, it is pushed upward under the action of the spring force, easily pushing the cardboard box out of the box-separating through hole 2022. This greatly facilitates the operator to pick up the box or realizes automated collection, avoiding product damage and low efficiency that may be caused by manual picking.

[0023] Reference Figures 1-6 A clearance groove 204 is provided on the lower mold base 3 below the top ear assembly 2031.

[0024] The clearance groove 204 facilitates the upward movement of the push rod 20311 using hydraulic cylinders or other driving devices.

[0025] Reference Figures 1-6 The die-cutting plate 201, the waste removal plate 202, and the top ear bottom plate 203 are fixedly connected into an integral module by connecting bolts 205 that pass through the three.

[0026] Reference Figures 1-6 The lower end of the upper die base 1 is fixedly connected to a stamping template 101, and the lower end of the upper die base 1 is fixedly connected to a waste removal punch 102. The position of the waste removal punch 102 corresponds vertically to the position of the waste removal hole 2021.

[0027] Reference Figures 1-6 The side walls of the die-cutting plate 201, the waste removal plate 202, and the top ear bottom plate 203 are all fixedly connected with lifting lugs 206.

[0028] Lifting lugs 206 are installed on the side walls of each panel, which allows the heavy integrated modules to be lifted conveniently and safely using cranes and other lifting equipment, reducing the labor intensity of workers and improving the safety of operation.

[0029] Working principle: Each time a module is replaced, simply align the positioning hole 403 on the module with the positioning pin 401 on the lower mold base 3 and lower it, then clamp it with quick clamps 402 to achieve fast and accurate positioning and installation. The waste removal plate 202 has a through-hole 2021 for full waste removal, which works in conjunction with the waste removal punch 102 of the upper die to remove all waste from non-product areas in one go and over a large area (i.e., full waste removal). Compared with traditional manual or partial waste removal, this method is extremely efficient and the waste removal is thorough and clean, which provides convenience for subsequent automatic waste collection or automated production and further improves the overall production rhythm. The 2022 through-hole allows each die-cut carton to exist independently in its own hole, achieving natural separation. Under the action of the return spring 20312, the upper end of the top ear assembly 2031 is pressed down during die cutting. After die cutting, it is pushed upward under the action of the spring force, easily pushing the cardboard box out of the box-separating through hole 2022. This greatly facilitates the operator to pick up the box or realizes automated collection, avoiding product damage and low efficiency that may be caused by manual picking. By integrating die-cutting, waste removal, and top ear functions into a complete die-cutting and waste removal integrated module 2, and fixing it with a quick positioning and locking mechanism 4 (positioning pin 401 + quick clamp 402), overall modular quick change is achieved. When changing products, there is no need to disassemble, align, and install individual components such as the die-cutting plate 201, waste removal plate 202, and bottom mold one by one. Simply loosen the quick clamp 402 to lift the entire integrated module away, and then lift and lock the new integrated module. This greatly simplifies the operation process, significantly shortens the mold change time, and improves the flexibility and production efficiency of the production line. It is especially suitable for small-batch, multi-variety production modes.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
