Technical Field

[0001] This utility model relates to the field of mold design technology, and more specifically, to a cutting mold with an easy-to-clean cutting blade. Background Technology

[0002] Die-cutting molds (or simply die-cutting dies) are used to stamp flat materials (such as paper, plastic, and thin metal sheets) into specific shapes. Their core function is to transform flat materials into three-dimensional products through precise cutting. For example, in the printing and packaging industry, die-cutting dies can stamp flat paper into the shape of cardboard boxes; in the electronics industry, die-cutting dies can be used to cut precision components such as mobile phone screen protectors and heat sinks.

[0003] Currently, when cutting, debris easily remains on the cutting blade, which can negatively impact subsequent processing. Traditional manual cleaning is inefficient and poses safety hazards. Therefore, some improved molds use water rinsing for cleaning. For example, a die-cutting mold with easy-to-clean blade design, as announced in patent number CN218425069U, uses a centrifugal pump to spray cleaning water from the tank through a nozzle, thereby rinsing and cleaning the die-cutting blade. During this process, a servo motor can drive the nozzle to move with the mounting block, improving the cleaning quality and efficiency of the die-cutting blade.

[0004] However, water rinsing also has some shortcomings. First, it is not easy to rinse away some stubborn and sticky debris, which may leave residue. Also, the high-speed water flow can cause splashing, which can easily dirty the environment. Overall, it has obvious shortcomings.

[0005] Therefore, in response to the above problems, the applicant needs to design a cutting die that is easy to clean. Utility Model Content

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0019] like Figures 1-7 As shown, the present invention provides a cutting die mold with an easy-to-clean cutter, comprising: a die base 1, a processing chamber 12 and a lower die groove 11 installed on the top of the die base 1, a cutter holder 14 installed on the top of the processing chamber 12 via a hydraulic lifting rod 13, a cutter 15 installed on the bottom of the cutter holder 14, and a cleaning assembly 2 installed inside the processing chamber 12, including a cylinder 22 sliding in an inclined groove 23 inside the processing chamber 12, the cylinder 22 being fixed on both sides of a cleaning frame 21, two cleaning frames 21 being provided and slidably installed on the bottom of a lifting plate 20, the two lifting plates 20 being connected to each other. There are two U-shaped plates 210, which are located above the knife holder 14. A horizontally movable brush plate 24 is installed inside the cleaning frame 21. The brush plate 24 is fixed to one side of the motor 25. The motor 25 is slidably installed inside the cleaning frame 21, and a gear 26 is installed at the output end of the motor 25. The gear 26 meshes with the toothed track 27 fixed inside the cleaning frame 21. Two reset rods 28 are fixed at the top of the lifting plate 20. The reset rods 28 pass through the processing chamber 12 to form a sliding connection. A spring 29 is connected between the lifting plate 20 and the processing chamber 12 and is sleeved on the outside of the reset rods 28.

[0020] Through the design of cleaning component 2, during processing, the workpiece is placed in the lower mold groove 11. The hydraulic lifting rod 13 is activated to drive the bottom cutter 15 of the tool holder 14 to descend and complete the cutting. This is the existing technology. When cleaning is required, the tool holder 14 is reset and then moved upward, driving the U-shaped plate 210, the lifting plate 20, and the cleaning frame 21 to move upward. The reset rod 28 plays a guiding role and compresses the spring 29 during the movement. When the cleaning frame 21 moves upward, the cylinder 22 slides in the inclined groove 23, causing the cleaning frame 21 to move horizontally. Finally, the brush plate 24 contacts both sides of the cutter 15. Note that the shape of the brush plate 24 is adapted to the cutter 15. Then, the motor 25 is started, and the output end of the motor 25 drives the... As gear 26 rotates, it meshes with the toothed track 27 fixed inside the cleaning frame 21. Under the rotation of gear 26, motor 25 slides horizontally along the toothed track 27 inside the cleaning frame 21, thereby driving the brush plate 24 fixed on one side of motor 25 to move horizontally on both sides of cutter 15. The brush plate 24 is provided with soft and elastic bristles. These bristles are closely attached to the blade surface of cutter 15. During the horizontal movement, they can effectively remove residual workpiece debris, oil stains and other impurities on the blade surface of cutter 15. After cleaning, all parts are reset. The compressed spring 29 can play an auxiliary reset role and use the rebound force to help drive the cleaning frame 21 back to the initial position.

[0021] A water spray assembly 3 is connected between the blade holder 14 and the machining chamber 12. This assembly sprays water onto both sides of the cutter 15 when the brush plate 24 cleans the blade surface. The water spray assembly 3 includes two horizontal pipes 31 fixed to the bottom of the blade holder 14, located on both sides of the cutter 15. A row of nozzles spraying water towards the upper end of the cutter 15 is installed on the side wall of each horizontal pipe 31. A connecting pipe installed at the top of the horizontal pipe 31 passes through the blade holder 14 and connects to a water receiving hopper 32. The water spray assembly 3 also includes a water tank 34 installed at the top of the machining chamber 12. Two water outlet pipes 33 installed at the bottom of the water tank 34 pass through… Through the processing chamber 12, the water outlet pipe 33 is located directly above the water receiving hopper 32, and a solenoid valve 36 is installed on the water outlet pipe 33. A controller 35 electrically connected to the solenoid valve 36 is installed at the bottom of the water tank 34. The start button of the controller 35 is located at the bottom. A pressing rod 37 is installed on the top of the tool holder 14. The pressing rod 37 can pass through the round opening of the processing chamber 12 to press the button of the controller 35. When the pressing rod 37 presses the button of the controller 35 to open the valve of the solenoid valve 36, the water receiving hopper 32 fits against the bottom of the processing chamber 12 and surrounds the outlet of the water outlet pipe 33 inside.

[0022] Furthermore, through the design of the water spray assembly 3, when the brush plate 24 contacts the cutter 15, the pressing rod 37 presses the button on the controller 35, and this action instantly triggers the opening of the solenoid valve 36. Water in the water tank 34, under the action of gravity, quickly flows downwards along the outlet pipe 33 and falls precisely into the water receiving hopper 32. Because the water receiving hopper 32 is fitted to the bottom of the processing chamber 12 and surrounds the outlet of the water pipe 33, the water will not splash everywhere. Instead, it flows steadily into the two horizontal pipes 31 fixed at the bottom of the cutter holder 14 through the connecting pipe installed at the top of the water receiving hopper 32. A row of nozzles installed on the side wall of the horizontal pipes 31 spray water towards the upper end of the cutter 15, and at this time, a fine stream of water is evenly sprayed out, closely coordinating with the cleaning action of the brush plate 24. On the one hand, the water stream can moisten the dirt on the blade surface of the cutter 15, making it easier for the bristles on the brush plate 24 to remove it, greatly improving the cleaning efficiency. This improves cleaning efficiency. On the other hand, the water flow can also wash away the debris and impurities brushed off by the brush plate 24 in time, preventing them from re-adhering to the surface of the cutter 15 and ensuring a more thorough cleaning effect. Note that a recycling box can be placed inside the lower mold groove 11. This is existing technology and will not be described in detail in the figure and text. After cleaning is completed, the cutter holder 14 begins to descend and reset under the action of the hydraulic lifting rod 13. As the cutter holder 14 moves down, the pressing rod 37 gradually disengages from the button of the controller 35. The solenoid valve 36 automatically closes under the control of the controller 35, and the water outlet pipe 33 stops discharging water. Since it is a natural flow, it will not cause a lot of water splashing and dirt splashing compared to using a water pump.

[0023] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
