Description

Technical Field

[0001] This invention belongs to the field of mold technology, and in particular relates to a punching die device that integrates automatic sawing and punching. Background Technology

[0002] In mold processing, there are two different processing techniques: sawing and punching. Sawing is a process of cutting materials using a saw blade. The saw blade is usually a toothed tool made of a high-hardness material, which cuts the material through high-speed rotation or reciprocating motion. Sawing is often used for rough dimensional cutting of materials, such as the division of metals, wood, and plastics. Punching is a process of separating material from a product by applying pressure, usually using a punch and a die. The punch, under the action of external force, breaks or extrudes the material to form a specific shape. Punching is usually used for processing thin sheets, such as metal sheets and plastic sheets. It is often used to manufacture precision parts, create holes, and cut contours. In the current technology, due to the differences between sawing and punching processes, sawing equipment and punching equipment are two separate independent devices. When sawing and punching are required, two different devices are started at different stations to process the product, resulting in increased processing costs, reduced efficiency, and different equipment requiring different installation and operating spaces, which is not conducive to equipment management.

[0003] In summary, existing mold processing technologies suffer from technical problems such as separation of sawing and punching, inconvenient installation and operation, high processing costs, and low efficiency. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this invention provides an automatic sawing and punching integrated die-cutting device, which integrates sawing and punching, improves installation and operation convenience, increases product processing efficiency, and reduces processing costs.

[0005] The automatic sawing and punching integrated punching die equipment provided by the present invention includes:

[0006] The upper punching die is set above the lower punching and sawing die and is used to press the ejected product at the upper limit of the lower punching and sawing die and to punch away the burrs around the ejected product during the pressing process.

[0007] The integrated punching and sawing lower die includes a sawing component, a product limiting component, and a sliding punching component mounted on the lower die base plate. After the upper punching die presses the ejected product, the sawing component moves to the side of the ejected product that is positioned at the upper limit of the product limiting component and saws off the annular flow channel of the ejected product. The ejected product has branch flow channels, and the sawn annular flow channel is connected to the ejected product through the branch flow channels. After the sawing component saws off the annular flow channel of the ejected product, it resets, and the sliding punching component operates to punch away the branch flow channels of the ejected product, the remaining burrs on the ejected product, and the slag on the ejected product.

[0008] Furthermore, the sawing assembly is located on the left side of the lower die base plate, and the product limiting assembly and the sliding punching assembly are both located on the right side of the lower die base plate; after the upper punching die presses the ejected product, the sawing assembly moves to the right to saw off the annular flow channel of the ejected product, and after sawing off the annular flow channel of the ejected product, the sawing assembly moves to the left to reset.

[0009] Furthermore, the row punching assembly includes a first row punching assembly and a second row punching assembly; the first row punching assembly and the second row punching assembly are distributed on two sides of the product limiting assembly, and the first row punching assembly and the sawing assembly are located in the same straight line direction.

[0010] Furthermore, after the sawing component is reset, the first sliding punching component and the second sliding punching component operate simultaneously. The first sliding punching component moves toward the product limiting component to punch away the branch flow channel of the molded product, the remaining burrs and slag on one side of the molded product, and the second sliding punching component moves toward the product limiting component to punch away the remaining burrs and slag on the other side of the molded product.

[0011] Furthermore, the first sliding punching assembly includes a first sliding cylinder, a first sliding bracket, and a first sliding punching head; the first sliding bracket is mounted on the lower die base plate; the first sliding cylinder is mounted on the first sliding bracket and drives the first sliding punching head to move toward the product limiting assembly to punch away the branch flow channel of the ejected product, the remaining burrs and slag on one side of the ejected product.

[0012] Furthermore, the second sliding punching assembly includes a second sliding cylinder, a second sliding bracket, and a second sliding punching head; the second sliding bracket is mounted on the lower die base plate; the second sliding cylinder is mounted on the second sliding bracket and drives the second sliding punching head to move toward the product limiting assembly to punch away the remaining burrs and slag on the other side of the ejected product.

[0013] Furthermore, the sawing assembly includes a third sliding cylinder and a motor-driven sawing assembly; the motor-driven sawing assembly is movably connected to the lower mold base plate and connected to the third sliding cylinder, and moves under the drive of the third sliding cylinder to drive the motor-driven sawing assembly to move to the side of the molded product at the upper limit of the product limiting assembly to cut off the annular flow channel of the molded product, and after the motor-driven sawing assembly cuts off the annular flow channel of the molded product, it drives the motor-driven sawing assembly to reset.

[0014] Furthermore, a third guide rail is provided on the lower mold base plate, and the motor-driven sawing assembly is movably connected to the third guide rail.

[0015] Furthermore, the motor-driven sawing assembly includes a drive motor, a motor mounting base, and a sawing disc; the drive motor is mounted on the motor mounting base, and the motor mounting base is movably connected to the third guide rail; the sawing disc is connected to the output shaft of the drive motor, and rotates or stops rotating with the stop action of the output shaft; when the sawing disc rotates, it performs a sawing action on the annular flow channel of the demolded product that is limited by the product limiting assembly, so as to cut off the connection between the annular flow channel and the demolded product.

[0016] Furthermore, the upper punching die includes an upper die body, upper die closing connecting pillars, and a punching tool assembly; the upper die closing connecting pillars are located at the four apex positions of the upper die body and are connected to the lower side of the upper die body; the punching tool assembly is assembled on the lower side of the upper die body, located in the inner area enclosed by the upper die closing connecting pillars at the four apex positions; the lower die base plate is provided with lower die closing connecting parts at the four apex positions; when the upper punching die presses the ejected product of the upper punching and sawing integrated lower die, the lower die closing connecting parts are aligned and inserted with the upper die closing connecting pillars, and the punching tool assembly is aligned with the ejected product to punch away the burrs of the pressed ejected product.

[0017] Compared with the prior art, the beneficial effects of this invention are as follows:

[0018] This invention provides an automatic sawing and punching integrated die device, including an upper punching die and an integrated punching and sawing lower die. The upper punching die is disposed above the integrated punching and sawing lower die and is used to press the die-out product at the upper limit of the integrated punching and sawing lower die, and to punch away the burrs around the die-out product during the pressing process. The integrated punching and sawing lower die includes a sawing component, a product limiting component, and a sliding punching component mounted on the lower die base plate; after the die-out product is pressed by the upper punching die, the sawing component moves to the side of the die-out product at the upper limit of the product limiting component and saws off the annular flow channel of the die-out product. The die-out product has branch flow channels, and the sawn annular flow channel is connected to the die-out product through the branch flow channels; after the sawing component cuts off the annular flow channel of the die-out product, it resets, and the sliding punching component operates to punch away the branch flow channels of the die-out product, the remaining burrs of the die-out product, and the slag on the die-out product. This automatic sawing and punching integrated die-cutting equipment combines sawing and punching, improving installation and operation convenience, increasing product processing efficiency, and reducing processing costs. Simultaneously, the cut-off annular flow channel connects to the ejected product via the branch flow channel. Because the cut-off annular flow channel does not fall directly and impact the sawing components, it protects the sawing components, thereby improving the service life and stability of the die-cutting equipment.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0033] See Figures 1-5This invention provides an integrated automatic sawing and punching die device, comprising: an upper punching die 1 and an integrated punching and sawing lower die 2. The upper punching die 1 is disposed above the integrated punching and sawing lower die 2 and is used to press the ejected product 6 at the upper limit of the integrated punching and sawing lower die 2, and to punch away the burrs around the ejected product 6 during the pressing process; the integrated punching and sawing lower die 2 includes a sawing component 21, a product limiting component 22, and a sliding punching component 23 mounted on the lower die base plate 20; the sawing component 21 moves to the upper limit of the product limiting component 22 after the upper punching die 1 presses the ejected product 6. The annular flow channel 60 of the molded product 6 is cut off on one side of the product 6. The molded product 6 has a branch flow channel 61. The cut-off annular flow channel 60 is connected to the molded product 6 through the branch flow channel 61. After the sawing component 21 cuts off the annular flow channel 60 of the molded product 6, it resets. The sliding punching component 23 operates to punch away the branch flow channel 61 of the molded product 6, the remaining burrs of the molded product 6, and the slag on the molded product 6.

[0034] It's important to note that the product runner is the channel through which material enters the mold cavity. However, once the product is molded, the runner is no longer needed and is irrelevant to the final product. If the runner is not removed, excess material will remain on the product, affecting not only its appearance but also its function and usability. Removing the runner results in a smoother and more even product surface, meeting customer requirements for appearance and precision. Slag pockets are typically formed by impurities generated at the end of the runner or during material flow. If these impurities are not removed, the surface quality of the product will be affected, potentially leading to defects during use. Removing slag pockets ensures surface quality and prevents impurities or irregular materials from affecting the product's appearance and performance. Blinders are excess, thin, sheet-like materials generated due to improper mold closure or excessive material. These excess materials not only affect the product's appearance but may also cause inconvenience during subsequent assembly or use, and even affect its functionality. Removing blisters results in neater, smoother edges, meeting customer requirements for a high-quality product appearance, while also avoiding inconvenience or potential functional problems caused by blistering.

[0035] It should also be noted that in this embodiment, the upper punching die 1 is positioned above the integrated punching and sawing lower die 2, used to press the ejected product 6 at the upper limit of the integrated punching and sawing lower die 2, and punches away the burrs around the ejected product 6 during the pressing process. This allows the upper punching die 1 to accurately remove the burrs from the product while applying pressure, thereby reducing process separation, improving product processing efficiency, ensuring the stability of the burr removal process, and avoiding secondary processing of the product. After the upper punching die 1 presses the ejected product 6, the sawing assembly 21 moves to the side of the ejected product 6 at the upper limit of the product limiting assembly 22 and cuts off the annular flow channel 60. The annular flow channel 60 is connected to the ejected product 6 through a branch flow channel 61, thereby preventing the annular flow channel 60 from falling off after cutting and avoiding interference with the sawing assembly 21. This structure not only protects the sawing assembly 21 and extends the service life of the equipment, but also ensures the continuity and smoothness of the cutting process and improves the stability of the equipment. After the sawing assembly 21 completes sawing, it returns to its initial position. Then, the sliding punching assembly 23 begins operation, punching away the branch runner 61, remaining burrs, and slag from the molded product 6, allowing the punching and sawing processes to be completed continuously and efficiently. By sawing before punching, the product's precision and integrity are ensured. When removing the branch runner 61, burrs, and slag, the punching assembly ensures a smooth product surface with no excess material residue, thereby improving the final product quality. It is important to note that in this embodiment, after the annular runner 60 is sawn off, it remains connected to the molded product 6 via the branch runner 61. This ensures that after sawing, the various parts of the annular runner 60 do not detach, thus avoiding interference with the sawing assembly 21. This not only improves equipment safety but also extends the equipment's service life. The branch runner 61 is separated from the product along with the annular runner 60 only through the subsequent punching process, ensuring the stability of the processing and the product's precision.

[0036] In some preferred embodiments, the sawing component 21 is located on the left side of the lower die base plate 20, while the product limiting component 22 and the sliding punching component 23 are both located on the right side of the lower die base plate 20. After the upper punching die 1 presses the ejected product 6, the sawing component 21 moves to the right to saw off the annular flow channel 60 of the ejected product 6. After sawing off the annular flow channel 60 of the ejected product 6, the sawing component 21 moves to the left to reset. It should be noted that the sawing component 21 and the punching component are separately arranged on both sides of the lower die base plate 20, which helps to separate their working paths and avoid mutual interference. The sawing component 21 is located on the left side, first completing the sawing of the annular flow channel 60, and then resetting to the left; while the punching component is located on the right side, punching the branch flow channel 61, burrs, and slag bags after the sawing operation is completed. Separating the sawing and punching functions and integrating them on different sides of the same lower die base plate 20 helps to reduce the impact of one operation on the other. After sawing is completed, the sawing component 21 resets without affecting subsequent punching operations. Each component can reset independently after completing its work, facilitating overall control and maintenance.

[0037] In some preferred embodiments, the row-position punching assembly 23 includes a first row-position punching assembly 230 and a second row-position punching assembly 231; the first row-position punching assembly 230 and the second row-position punching assembly 231 are distributed on two sides of the product limiting assembly 22, and the first row-position punching assembly 230 and the sawing assembly 21 are located in the same straight line direction. Further, after the sawing assembly 21 is reset, the first row-position punching assembly 230 and the second row-position punching assembly 231 operate simultaneously. The first row-position punching assembly 230 moves towards the product limiting assembly 22 to punch away the branch flow channel 61 of the molded product 6, the remaining burrs and slag on one side of the molded product 6, and the second row-position punching assembly 231 moves towards the product limiting assembly 22 to punch away the remaining burrs and slag on the other side of the molded product 6.

[0038] It should be noted that in this embodiment, the first row-position punching component 230 and the second row-position punching component 231 are arranged on two sides of the product limiting component 22, and the first row-position punching component 230 and the sawing component 21 are located on the same straight line. After the sawing component 21 completes the sawing of the annular flow channel 60 and resets, the two punching components operate simultaneously, punching the two sides of the product from different directions. The two components can work simultaneously to quickly remove the branch flow channel 61, burrs, and slag, thereby reducing the time interval during the punching process and improving processing efficiency. By simultaneously removing burrs and slag from both sides of the product, the need for secondary processing can be avoided. All unnecessary excess material can be removed at once, effectively reducing the product processing cycle, avoiding the cost and time consumption of secondary processing, and thus improving overall production efficiency.

[0039] In some preferred embodiments, the first sliding punching assembly 230 includes a first sliding cylinder 2300, a first sliding bracket 2301, and a first sliding punching head 2302; the first sliding bracket 2301 is mounted on the lower mold base plate 20; the first sliding cylinder 2300 is mounted on the first sliding bracket 2301 and drives the first sliding punching head 2302 to move toward the product limiting assembly 22 to punch away the branch flow channel 61 of the molded product 6 and the remaining burrs and slag on one side of the molded product 6. The second sliding punching assembly 231 includes a second sliding cylinder 2310, a second sliding bracket 2311, and a second sliding punching head 2312. The second sliding bracket 2311 is mounted on the lower die base plate 20. The second sliding cylinder 2310 is mounted on the second sliding bracket 2311 and drives the second sliding punching head 2312 to move towards the product limiting assembly 22, punching away the remaining burrs and slag on the other side of the ejected product 6. It should be noted that in this embodiment, by setting two punching assemblies, the product can be punched at different positions, effectively removing excess material (such as branch channels 61, burrs, and slag) from the ejected product 6 in steps, ensuring that each part can be accurately removed. In addition, setting separate first and second sliding punching heads allows each punching head to focus on removing excess material from a specific position, reducing possible errors during the punching process and improving the quality of the final product. Distributing the punching task across different punching components allows for a more compact and easier-to-design overall mold structure, reduces manufacturing difficulty, and facilitates maintenance and replacement of punching components. For complex-shaped products with varying amounts of excess material in different locations, setting punching components at different positions allows for targeted removal of excess material from specific locations based on the product's actual structure and shape, resulting in products that better meet design requirements.

[0040] In some preferred embodiments, the sawing assembly 21 includes a third positioning cylinder 210 and a motor-driven sawing assembly 211. The motor-driven sawing assembly 211 is movably connected to the lower mold base plate 20 and connected to the third positioning cylinder 210. Driven by the third positioning cylinder 210, it moves to move to the side of the ejected product 6 at the upper limit of the product limiting assembly 22 to saw off the annular flow channel 60 of the ejected product 6. After the motor-driven sawing assembly 211 cuts off the annular flow channel 60 of the ejected product 6, it resets. Further, a third positioning guide rail 200 is provided on the lower mold base plate 20, and the motor-driven sawing assembly 211 is movably connected to the third positioning guide rail 200. Furthermore, the motor-driven sawing assembly 211 includes a drive motor 2110, a motor mounting base 2111, and a sawing disc 2112. The drive motor 2110 is mounted on the motor mounting base 2111, which is movably connected to the third guide rail 200. The sawing disc 2112 is connected to the output shaft of the drive motor 2110 and rotates or stops rotating with the stop action of the output shaft. When the sawing disc 2112 rotates, it performs a sawing action on the annular flow channel 60 of the molded product 6, which is limited by the product limiting assembly 22, to sever the connection between the annular flow channel 60 and the molded product 6. It should be noted that in this embodiment, the sawing assembly 21 is specifically designed to cut the annular flow channel 60 of the molded product 6. This flow channel is usually used to guide molten material to fill the mold cavity during injection molding. After demolding, these flow channels become waste and need to be precisely removed. The motor-driven sawing assembly 211 ensures the precision and quality of the cutting process, preventing damage to the product body. The motor-driven sawing assembly 211 includes a drive motor 2110, a motor mounting base 2111, and a sawing disc 2112, facilitating maintenance and replacement when needed. It should be noted that improper cutting of the annular flow channel 60 may cause stress concentration in the product body, leading to deformation or other defects. In this embodiment, the motor-driven sawing assembly 21 can effectively reduce vibration and impact during the cutting process by precisely controlling the rotational speed and movement speed of the sawing disc 2112, thus reducing the risk of product damage. Furthermore, in this embodiment, by providing guide rails on the lower die base plate 20, the movement path of the motor-driven sawing assembly 211 is effectively controlled and stabilized, ensuring consistency and precision during the sawing process. The guide rails can also reduce cutting deviations caused by offset or shaking during the cutting process, improving the flatness and quality of the product's cut surface.

[0041] In some preferred embodiments, the upper punching die 1 includes an upper die body 10, an upper die closing connecting post 11, and a punching tool assembly 12; the upper die closing connecting post 11 is located at the four corners of the upper die body 10 and is connected to the lower side of the upper die body 10; the punching tool assembly 12 is assembled on the lower side of the upper die body 10, within the area enclosed by the upper die closing connecting post 11 at the four corners; the lower die base plate 20 is provided with lower die closing connecting parts 201 at the four corners; when the upper punching die 1 presses the upper die 2 of the punching and sawing integrated lower die 2 to the upper die, the lower die closing connecting parts 201 are aligned and inserted with the upper die closing connecting post 11, and the punching tool assembly 12 is aligned with the upper die 6 to punch and remove the burrs of the pressed upper die 6. It should be noted that in this embodiment, by setting the upper die closing connecting post 11 at the four corners of the upper die body 10 and setting the lower die closing connecting part 201 at the four corners of the lower die base plate 20, the stability of the movement path of the upper die during the downward punching process can be ensured. The alignment and insertion of the upper die closing connecting post 11 and the lower die closing connecting part 201 can effectively prevent offset, shaking or misalignment during the punching process, thereby improving the accuracy of the punching tool. During the alignment process between the punching upper die 1 and the punching saw integrated lower die 2, the cooperation of the lower die closing connecting part 201 and the upper die closing connecting post 11 allows the punching upper die 1 to press the ejected product 6 before punching, ensuring that the position of the product is fixed during the punching process and preventing the product from being incompletely punched or damaged due to loosening or displacement. The punching tool assembly 12 is located on the lower side of the upper mold body 10 and within the internal area enclosed by the four upper mold closing connecting pillars 11. This not only saves space but also makes the entire mold structure more compact, facilitating assembly and operation. The punching tool assembly 12 removes the burrs from the ejected product 6 through precise alignment and insertion, effectively removing excess burrs and ensuring a smooth and flat product surface. This prevents burr residue from affecting the product's appearance quality and performance.

[0042] In some further preferred embodiments, an automation system control box 3 and upper / lower mold closing induction switches 4 are provided on the lower mold base plate 20; the automation system control box 3 and the upper / lower mold closing induction switches 4 are located on one side of the sawing assembly 21; product placement induction switches 5 are also provided on both ends of the product limiting assembly 22; the upper / lower mold closing induction switches 4, the product placement induction switches 5, the upper punching mold 1, the sawing assembly 21, and the sliding punching assembly 23 are all connected to the automation system control box 3 via electrical signals. It should be noted that, in this embodiment, by providing the automation system control box 3 on the lower mold base plate 20, the entire punching and sawing process can be managed by a central control system. The automation system control box 3 receives signals from each induction switch and triggers corresponding actions, such as mold closing, punching, and sawing, based on these signals, thereby achieving full automation of the production process and improving production efficiency. Among them, the upper / lower mold closing induction switches 4 and the product placement induction switches 5 can monitor the status of the mold and the position of the product in real time, ensuring that subsequent processes are triggered only when all conditions are met. For example, the punching operation will only be initiated when the product is correctly placed and the upper and lower dies are correctly closed, preventing product damage or equipment failure due to misoperation. The automated system control box 3 centrally manages all sensor switches and operating components, making system debugging and maintenance simpler. Equipment operators can easily adjust various parameters and perform system calibration through the control box, and can quickly locate the problem in case of a malfunction, reducing downtime.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
