Description

Technical Field

[0001] This invention relates to the field of die-cutting device technology, and in particular to a composite die-cutting mold for mass production. Background Technology

[0002] A die-cutting mold is made by cutting a slit in a sheet of material of a certain thickness according to the size of the die-cutting blade, and then inserting the blade into it. The width of the slit must be adapted to the width of the die-cutting blade, and the two sides of the slit wall must fit tightly with the blade to fix the die-cutting blade. Existing die-cutting molds use two or more materials as substrates, and then cut slits of different precision on the surface of the substrates. The blade is fixed by the slits on the substrates of different materials. However, the use of multiple substrates stacked together to form slits requires high precision of the equipment. In addition, cutting high-precision slits on the substrates requires continuous operation for a long time. During this process, due to the inability to control and stop the equipment, many unexpected situations often occur, leading to the failure of cutting the slits. Summary of the Invention

[0003] The purpose of this invention is to solve the problem that the existing technology requires high precision equipment for engraving slits, and at the same time, the continuous operation of the equipment is required during engraving slits, which leads to the easy failure when opening slits with high precision requirements. Therefore, this invention proposes a composite die for mass production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A composite die for mass production includes an upper substrate and a lower substrate. The sides of the upper substrate and the lower substrate are connected by a snap-fit ​​assembly. An auxiliary pressing assembly is provided on the top of the upper substrate. A second upper substrate is tightly attached to the bottom of the auxiliary pressing assembly. The bottom of the second upper substrate is inserted into the inner sidewall of the upper substrate. The connection between the upper substrate and the second upper substrate forms a top die seam. A second lower substrate is inserted into the inner wall of the lower substrate. The connection between the lower substrate and the second lower substrate forms a bottom die seam. An outer fixing ring and an inner fixing ring are fixed to the bottom of the upper substrate and the second upper substrate. An adjusting bolt is threaded to the side of both the outer fixing ring and the inner fixing ring. An outer fan-shaped sleeve and an inner fan-shaped sleeve are sleeved at the ball head of one end of the adjusting bolt. A clamping assembly is provided inside both the outer fan-shaped sleeve and the inner fan-shaped sleeve.

[0006] The clamping assembly includes irregular mounting grooves formed inside the outer and inner fan-shaped sleeves. A sliding plate is tightly fitted to the bottom side of the mounting groove. A spring is fixed to the side of the sliding plate. A sliding rod is fixed to one end of the spring. A folding rod is hinged to the top side of the sliding rod via a shaft. A limit rod is hinged to one end of the folding rod. The two ends of the limit rod are respectively hinged to the inner wall of the mounting groove and the two sides of the sliding rod via shafts. One end of the sliding rod passes through the outer or inner fan-shaped sleeve and is fixed with a secondary clamping plate. The gap formed between the opposite sides of the outer and inner fan-shaped sleeves and the opposite sides of the two secondary clamping plates is a central cut seam.

[0007] Preferably, there are several outer fan-shaped sleeves and inner fan-shaped sleeves, and the several outer fan-shaped sleeves and inner fan-shaped sleeves form two concentric rings.

[0008] Preferably, both the outer fan-shaped sleeve and the inner fan-shaped sleeve have a boss fixed at their bottoms, and the bottom of the boss is inserted into the inner wall of a groove opened on the upper surface of the lower substrate and the second lower substrate.

[0009] Preferably, the bottom of the second lower substrate is threaded with a second adjusting bolt, and the top of the second adjusting bolt passes through the second lower substrate and is fixedly connected to a pressing platform.

[0010] Preferably, the side of the pressing table is provided with a threaded groove, and the lower surface of the threaded groove is in close contact with the upper surface of the bottom end of the inner fixing ring.

[0011] Preferably, the engaging assembly includes engaging grooves respectively formed on the sides of the upper substrate and the lower substrate, an I-shaped locking block inserted into the inner wall of the engaging groove, a fixing bolt inserted into the top of the upper substrate, and the bottom of the fixing bolt passing through the upper substrate and the lower substrate and inserted into the interior of the I-shaped locking block.

[0012] Preferably, a connecting ring is fixed to the top of the fixing bolt, the lower surface of the connecting ring is tightly fitted to the top of the upper substrate, and an arc-shaped groove is provided at each of the four inner diagonal points of the connecting ring.

[0013] Preferably, the auxiliary pressure assembly includes a fixed cylinder inserted into the inner wall of an arc-shaped groove opened at four inner diagonal points of the connecting ring. The bottom of the fixed cylinder is fixed to the top of the upper substrate. A telescopic rod is fixed to the top of the fixed cylinder. A second spring is fixed between the bottom of the telescopic rod and the inner bottom wall of the fixed cylinder. A pressure leg is fixed to the side of the telescopic rod. The bottom of the pressure leg is tightly fitted to the top of the second upper substrate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The present invention, through the setting of an outer fan-shaped sleeve and an inner fan-shaped sleeve, can be enclosed in a circle or other shapes as shown in the figure. The central slit formed by this effectively reduces the difficulty of precision machining, avoids the problem of low error rate when the processing device needs to work continuously when processing precision slits, greatly improves the success rate of slit engraving device, and avoids rework or damage to the substrate, which increases costs and wastes time.

[0016] 2. The present invention, through the setting of the auxiliary clamping plate, can tighten the middle cutting slit formed by the auxiliary clamping plate when the blade moves upward. Specifically, the folding rod drives the limiting rod to move relative to each other, thereby driving the auxiliary clamping plate to tighten, so as to reduce the upward movement distance of the blade and avoid the blade moving upward and affecting the cutting effect. At the same time, the auxiliary clamping plate can also move upward when tightened, thereby increasing the contact area between the middle cutting slit and the blade to reduce the breakage rate of the blade moving up and down under overload.

[0017] 3. The present invention, by setting the upper substrate on the second upper substrate and the lower substrate on the second lower substrate, forms a top slit and a bottom slit that can be processed by rough machining, thereby reducing the difficulty of making slits on the substrate. The top slit and the bottom slit are both auxiliary to the middle slit to fix the blade body, thereby reducing the difficulty of aligning the slits when stacking multiple substrates.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] Example, refer to Figure 1-8 A composite die for mass production includes an upper substrate 1 and a lower substrate 2. The sides of the upper substrate 1 and the lower substrate 2 are connected by a locking assembly. The locking assembly further includes locking grooves 23 respectively opened on the sides of the upper substrate 1 and the lower substrate 2. An I-shaped locking block 24 is inserted into the inner wall of the locking groove 23. A fixing bolt 25 is inserted into the top of the upper substrate 1. The bottom of the fixing bolt 25 passes through the upper substrate 1 and the lower substrate 2 in sequence and is inserted into the interior of the I-shaped locking block 24. A connecting ring 26 is fixed to the top of the fixing bolt 25. The lower surface of the connecting ring 26 is tightly attached to the top of the upper substrate 1. An arc-shaped groove is opened at each of the four inner diagonal corners of the connecting ring 26.

[0029] The further advantage of adopting the above is that the middle base plate consisting of the upper base plate 1, the lower base plate 2, the outer fan-shaped sleeve 10, and the inner fan-shaped sleeve 11 can be fixed again by the I-shaped locking block 24 in the locking assembly. At the same time, it is also convenient for the staff to separate the upper base plate 1 and the lower base plate 2 to replace the outer fan-shaped sleeve 10 and the inner fan-shaped sleeve 11 during maintenance, which effectively reduces the difficulty of maintenance equipment and saves maintenance costs and reduces resource waste.

[0030] The top of the upper substrate 1 is provided with an auxiliary pressure assembly. The auxiliary pressure assembly further includes a fixing cylinder 27 that is inserted into the inner wall of the arc-shaped grooves opened at the four inner diagonal corners of the connecting ring 26. The bottom of the fixing cylinder 27 is fixed to the top of the upper substrate 1. A telescopic rod 28 is fixed to the top of the fixing cylinder 27. A second spring 29 is fixed between the bottom of the telescopic rod 28 and the inner bottom wall of the fixing cylinder 27. A pressure leg 30 is fixed to the side of the telescopic rod 28. The bottom of the pressure leg 30 is tightly attached to the top of the second upper substrate 3.

[0031] The further advantage of adopting the above is that the auxiliary pressure component can buffer the second upper substrate 3 when the blade body is subjected to overload displacement, so as to reduce the damage to the second upper substrate 3 at the top of the blade body, thereby increasing the service life of the device, reducing the replacement rate of parts and reducing resource waste.

[0032] The bottom of the auxiliary pressure assembly is tightly fitted with the second upper substrate 3. The bottom of the second upper substrate 3 is inserted into the inner wall of the upper substrate 1. The connection between the upper substrate 1 and the second upper substrate 3 forms a top slit 4. The inner wall of the lower substrate 2 is fitted with the second lower substrate 5. The connection between the lower substrate 2 and the second lower substrate 5 forms a bottom slit 6. The bottom of the upper substrate 1 and the second upper substrate 3 is fixed with an outer fixing ring 7 and an inner fixing ring 8. The sides of the outer fixing ring 7 and the inner fixing ring 8 are threaded with adjusting bolts 9. An outer fan-shaped sleeve 10 and an inner fan-shaped sleeve 11 are fitted onto the ball head of one end of the adjusting bolt 9. The number of outer fan-shaped sleeves 10 and inner fan-shaped sleeves 11 is... There are several outer fan-shaped sleeves 10 and inner fan-shaped sleeves 11 forming two concentric rings. The bottom of both the outer fan-shaped sleeves 10 and the inner fan-shaped sleeves 11 is fixed with a boss 20. The bottom of the boss 20 is inserted into the inner wall of the groove opened on the upper surface of the lower substrate 2 and the second lower substrate 5. The bottom of the second lower substrate 5 is threaded with a second adjusting bolt 21. The top of the second adjusting bolt 21 passes through the second lower substrate 5 and is fixedly connected to a pressing platform. The side of the pressing platform is provided with a threaded groove 22. The lower surface of the threaded groove 22 is tightly attached to the upper surface of the bottom end of the inner fixing ring 8. The outer fan-shaped sleeves 10 and the inner fan-shaped sleeves 11 are both provided with clamping components.

[0033] It is worth noting that the threaded groove 22 can connect the second adjusting bolt 21 with the inner fixing ring 8 to fix the second lower base plate 5. Similarly, the threaded groove 22 can also be fixed after the second lower base plate 5 is moved, so as to facilitate the alignment and fixing of the top blade slot 4, the bottom blade slot 6 and the middle blade slot 19. The boss 20 is set to facilitate the partial displacement of the outer fan-shaped sleeve 10 and the inner fan-shaped sleeve 11, so as to facilitate the middle blade slot 19 to better fit the blade body.

[0034] The clamping assembly includes an irregular mounting groove 12 formed inside the outer fan-shaped sleeve 10 and the inner fan-shaped sleeve 11. A sliding plate 13 is tightly fitted to the bottom side of the mounting groove 12. A spring 14 is fixed to the side of the sliding plate 13. A sliding rod 15 is fixed to one end of the spring 14. A folding rod 16 is hinged to the top side of the sliding rod 15 via a shaft. A limiting rod 17 is hinged to one end of the folding rod 16. The two ends of the limiting rod 17 are respectively hinged to the inner wall of the mounting groove 12 and the two sides of the sliding rod 15 via shafts. One end of the sliding rod 15 passes through the outer fan-shaped sleeve 10 or the inner fan-shaped sleeve 11 and is fixed with a secondary clamping plate 18. The gap formed between the opposite sides of the outer fan-shaped sleeve 10 and the inner fan-shaped sleeve 11 and the opposite sides of the two secondary clamping plates 18 is a central cut slit 19.

[0035] It is worth noting that the secondary clamping plate 18, as well as the outer fan-shaped sleeve 10 and the inner fan-shaped sleeve 11, are made of wood. Wood can increase the friction on the blade and reduce damage to the blade. At the same time, it can further reduce the difficulty of precision machining the middle blade seam 19 of the device.

[0036] When using this invention, as Figure 3 As shown, remove the retaining bolt 25 from the upper substrate 1 and the lower substrate 2, then remove the I-shaped locking block 24 from the engaging groove 23, thereby removing the lower substrate 2, and then insert the blade as shown. Figure 6 The middle slit 19 shown extends inside the blade until the top of the blade touches the surface. Figure 5 The top slit 4 is shown;

[0037] When the cutter body partially mismatches with the cutter kerf, rotate along the thread direction as follows: Figure 6 The adjusting bolt 9 shown makes the central blade seam fit snugly against the blade body, and finally... Figure 7 When the second adjusting bolt 21 is rotated, the threaded groove 22 fits into the inner sector sleeve 11 to fix the second lower base plate 5. Finally, the lower base plate 2 is fixed to the bottom of the outer sector sleeve 10 by aligning it with the boss 20 at the bottom of the outer sector sleeve 10. Finally, the I-shaped clip 24 is inserted into the engagement groove 23, and the fixing bolt 25 moves down to fix the I-shaped clip 24 to the upper base plate 1 and the lower base plate 2.

[0038] When the blade moves upward due to excessive force, such as Figure 6 As shown, during the upward movement of the sub-clamping plate 18, the folding rod 16 will move upward, thereby pulling one end of the limiting rod 17 upward, so that the sub-clamping plate 18 relatively tightens and fixes the blade body.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
