Description

Technical Field

[0001] This invention relates to the field of die-cutting technology, specifically to an adjustable-spacing resin die. Background Technology

[0002] With the development of science and technology, die-cutting and creasing dies are widely used in packaging printing, electronics, blister packaging and other industries. During processing, the die is usually clamped on the worktable of a die-cutting machine. Through the relative movement of the die template and the die-cutting base plate, various shapes of flat products, flat products with concave and convex patterns or creasing lines are cut or pressed out. Further, more exquisite products can be obtained through color printing or hot stamping, or flat products with creasing lines can be folded into various three-dimensional products. Because the resin die used in current processing is made of multiple independent resin board die layers stacked and connected by a fixed structure, it restricts the position change of the blades on the die. It is necessary to replace the die to adjust the blade spacing, or to make multiple holes in the die for the blade to disassemble and reposition. This can easily cause damage to the blades and bring certain adverse effects to actual use. Therefore, improvements are needed. Summary of the Invention

[0005] Preferably, both sides of the inner wall of the outer frame are fixedly connected to a limiting guard plate, and the internal thread of the limiting guard plate is connected to a positioning screw, and one end of the positioning screw is connected to the internal thread of the resin die-cutting main board.

[0006] Preferably, the limiting component includes a limiting plate and a limiting groove. The limiting plate is fixedly connected to the side of the threaded sleeve plate, and the limiting groove is formed on the side of the inner wall of the tool holder. The inner wall of the limiting groove and the surface of the limiting plate are slidably connected.

[0007] Preferably, a side plate is fixedly connected to the side of the tool holder, a pull rod is slidably connected to the inner wall of the side plate, a sandpaper panel is fixedly connected to one end of the pull rod, and a compression spring is connected to the front side of the sandpaper panel and the rear side of the side plate through a damping pad.

[0008] Preferably, the top of the pull rod is provided with a connecting slot, and a connecting rod is engaged with the inner wall of the connecting slot.

[0009] Preferably, an abutment pad is fixedly connected to the rear side of the inner wall of the clamping plate, and the abutment pad is made of rubber.

[0010] Preferably, the bottom of the stop plate is fixedly connected to an anti-slip plate, and the surface of the anti-slip plate is coated with a wear-resistant coating.

[0011] Preferably, a vibration sensor is fixedly installed inside the stop plate, and the sensing end of the vibration sensor is connected to the surface of the anti-slip plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. By fixing the positioning screws, limiting guard plates, and mounting plates, the outer frame, shock-absorbing support plate, and resin die-cutting main board can be spliced ​​and fixed into a whole, completing the firm assembly of the entire resin die-cutting mold;

[0014] 2. When clamping blades of different lengths is required, the setting of the limiting component enables the rotation of the bidirectional threaded rod to drive the threaded sleeves on different threaded surfaces to move in opposite directions. The movement of the threaded sleeves can drive the clamping plates to move. After the two clamping plates are adjusted to the appropriate position.

[0015] 3. The first threaded rod moves by rotating inside the first threaded groove. Under the constraint of the straight rod and the straight groove, the rotation of the first threaded rod can push the clamping plate to move, clamping the blade inside the clamping plate. The abutment pad inside the clamping plate can reduce the recoil force on the blade during subsequent use. When the user needs to adjust the spacing between connected blades, the user can push the entire tool holder to move. After the tool holder moves to the appropriate position, the user can use the second threaded groove to rotate the second threaded rod, pushing the stop plate into the inner wall of the stop groove. The continuously pressed stop plate can press against the stop groove to prevent slippage. The anti-slip plate further enhances the stability of the tool holder. At the same time, the user can lower the sandpaper panel. The compression spring, under the pressure of the damping pad, allows the sandpaper panel to abut against the resin die main board to achieve secondary positioning. The vibration sensor can detect whether the tool holder is slipping. The connecting rod allows the user to pull two sandpaper panels in one direction at a time.

[0016] 4. The baffle can protect the workpiece in the front and rear positions. Under the action of the gas spring, the baffle can move in the front and rear directions according to the fixed point of contact, and the slide rod can constrain the normal movement trajectory of the cross plate and the baffle on it.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 8This invention provides a technical solution: an adjustable-spacing resin die-cutting mold, comprising an outer frame 1, an mounting plate 2 fixedly connected to the inner wall of the outer frame 1, a shock-absorbing support plate 3 fixedly mounted on the surface of the mounting plate 2, a resin die-cutting main plate 4 snapped between two shock-absorbing support plates 3, a movable groove 5 formed on the surface of the resin die-cutting main plate 4, a movable plate 6 movably connected to the inner wall of the movable groove 5, a tool holder 7 fixedly connected to the surface of the movable plate 6, a bidirectional threaded rod 8 rotatably connected to the inner wall of the tool holder 7 via a bearing, and matching threaded sleeves 9 threadedly connected to different threads on the surfaces of the bidirectional threaded rod 8, a limit assembly connected to the side of the threaded sleeve 9, a clamping plate 10 fixedly connected to the front of the threaded sleeve 9, a first threaded groove 11 formed on the side of the clamping plate 10, a first threaded rod 12 threadedly connected to the inner wall of the first threaded groove 11, and an anti-slip clamping plate 13 rotatably connected to one end of the first threaded rod 12 via a pin. A straight rod 14 is fixedly connected to the side of the clamping plate 10. A straight groove 15 is opened on the side of the inner wall of the clamping plate 10. The inner wall of the straight groove 15 is slidably connected to the surface of the straight rod 14. A fixing plate 16 is fixedly connected to the top of the tool holder 7. A second threaded groove 17 is opened inside the fixing plate 16. A second threaded rod 18 is threadedly connected to the inner wall of the second threaded groove 17. A stop plate 19 is rotatably connected to the bottom of the second threaded rod 18 through a pin. The resin die plate 4 has a stop plate 19 near its top. A stop groove 20 is provided on the surface, and the inner wall of the stop groove 20 is engaged with the surface of the stop plate 19. A baffle 21 is slidably connected inside the shock-absorbing support plate 3. A cross plate 22 is fixedly connected to the rear side of the baffle 21. A slide rod 23 is fixedly connected to the rear side of the resin die-cutting main plate 4. The surface of the slide rod 23 is slidably connected to the inner wall of the cross plate 22. A gas spring 24 is fixedly connected to the surface of the cross plate 22. One end of the gas spring 24 abuts against the rear surface of the resin die-cutting main plate 4.

[0028] Furthermore, both sides of the inner wall of the outer frame 1 are fixedly connected with limiting plates 25. The internal threads of the limiting plates 25 are connected with positioning screws 26, and one end of the positioning screws 26 is connected to the internal threads of the resin die-cutting main board 4. The limiting plates 25 can abut against the shock-absorbing support plates 3 to constrain the position. Then, the user can snap the resin die-cutting main board 4 between the two shock-absorbing support plates 3 to complete the initial fixation of the resin die-cutting main board 4, and rotate the positioning screws 26 into the resin die-cutting main board 4 and the limiting plates 25 to complete the firm assembly of the entire resin die-cutting mold.

[0029] Furthermore, the limiting component includes a limiting plate 27 and a limiting groove 28. The limiting plate 27 is fixedly connected to the side of the threaded sleeve 9, and the limiting groove 28 is formed on the side of the inner wall of the tool holder 7. The inner wall of the limiting groove 28 and the surface of the limiting plate 27 are slidably connected. Through the setting of the limiting plate 27 and the limiting groove 28, the movement trajectory of the threaded sleeve 9 is limited, so that the rotation of the bidirectional threaded rod 8 can drive the threaded sleeves 9 on different threaded surfaces to move in opposite directions.

[0030] Furthermore, a side plate 29 is fixedly connected to the side of the tool holder 7. A pull rod 30 is slidably connected to the inner wall of the side plate 29. A sandpaper panel 31 is fixedly connected to one end of the pull rod 30. Compression springs 32 are connected to the front side of the sandpaper panel 31 and the rear side of the side plate 29 through damping pads. Under the pressure of the damping pads, the compression springs 32 allow the sandpaper panel 31 to abut against the resin die main plate 4 for secondary positioning. A connecting slot 33 is provided at the top of the pull rod 30. A connecting rod 34 is engaged with the inner wall of the connecting slot 33. The connecting rod 34 allows the user to pull both sandpaper panels 31 in one direction at a time.

[0031] Furthermore, an abutment pad 35 is fixedly connected to the rear side of the inner wall of the clamping plate 10. The abutment pad 35 is made of rubber. The abutment pad 35 inside the clamping plate 10 can reduce the recoil force experienced by the blade during subsequent use.

[0032] Furthermore, an anti-slip plate 36 is fixedly connected to the bottom of the stop plate 19, and the surface of the anti-slip plate 36 is coated with a wear-resistant coating. A vibration sensor 37 is fixedly installed inside the stop plate 19, and the sensing end of the vibration sensor 37 is connected to the surface of the anti-slip plate 36. The anti-slip plate 36 further enhances the stability of the tool holder 7, and the vibration sensor 37 can subsequently sense whether the tool holder 7 has become loose.

[0033] Working Principle: When using this adjustable-spacing resin die, first place the outer frame 1 and shock-absorbing support plate 3, etc., together. Place the shock-absorbing support plate 3 inside the outer frame 1, and connect and fix it using the mounting plate 2. The limiting guard plate 25 can abut against the shock-absorbing support plate 3 to constrain its position. Then, the user can snap the resin die main plate 4 between the two shock-absorbing support plates 3 to initially fix the resin die main plate 4. Finally, rotate the positioning screw 26 onto the resin die main plate 4 and the limiting guard plate 25 to complete the secure assembly of the entire resin die. The user can adjust the spacing according to different situations. When replacing the main plate 4 of the resin die-cutting mold, and when the user needs to clamp blades of different lengths, the user can rotate the bidirectional threaded rod 8. Through the setting of the limiting plate 27 and the limiting groove 28, the movement trajectory of the threaded sleeve 9 is limited, allowing the rotation of the bidirectional threaded rod 8 to drive the threaded sleeves 9 on different threaded surfaces to move in opposite directions. The movement of the threaded sleeves 9 can drive the clamping plate 10 to move. After the two clamping plates 10 are adjusted to the appropriate position, the user can rotate the first threaded rod 12 inside the first threaded groove 11. Under the restriction of the straight rod 14 and the straight groove 15, the rotation of the first threaded rod 12 is... The clamping plate is moved to clamp the blade inside the clamping plate 10. The abutment pad 35 inside the clamping plate 10 reduces the recoil force experienced by subsequent blades during use. When the user needs to adjust the spacing between connected blades, the user can move the entire tool holder 7. After the tool holder 7 is moved to the appropriate position, the user can use the second threaded groove 17 to rotate the second threaded rod 18, pushing the stop plate 19 into the inner wall of the stop groove 20. The continuously pressed stop plate 19 can press against the stop groove 20 to prevent slippage. The anti-slip plate 36 further enhances the stability of the tool holder 7. At the same time, the user can pull up... When the sandpaper panel 31 is lowered, the compression spring 32, under the pressure of the damping pad, allows the sandpaper panel 31 to abut against the resin die main board 4 for secondary positioning. The vibration sensor 37 can then sense whether the tool holder 7 is slipping. The connecting rod 34 allows the user to pull both sandpaper panels 31 in one direction at a time. The baffle 21 can protect the workpiece in the front and back positions. Under the action of the gas spring 24, the baffle 21 can move in the front and back directions according to the abutment fixing point. The sliding rod 23 can constrain the normal movement trajectory of the cross plate 22 and the baffle 21 on it, bringing convenience to the user's work.
