Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting equipment, in particular to a mold and a die-cutting machine with a waste removal function. Background Art

[0002] Traditional die-cutting is a cutting process used in the post-production of printed materials. Die-cutting allows printed materials or other paper products to be cut according to pre-designed patterns using a die-cutting plate, thus expanding the possibilities of printed materials into shapes that are no longer limited to straight edges or right angles. Traditional die-cutting involves using a die-cutting blade, assembled into a die-cutting plate according to the design requirements, and then applying pressure to the printed material or other sheet material to create the desired shape or cut.

[0003] In existing production technology, when a die-cutting machine performs through-hole die-cutting on a product, a correspondingly shaped cutter is required on the lower side of the upper die. A waste removal hole is also provided on the upper die, and the cutter is located at the edge of the hole. After die-cutting, the waste removed by the cutter will be in the waste removal hole. The waste is then removed by the air blowing assembly on the frame or manually. However, since the pressure of the upper die is not fixed, waste may remain attached to the product, requiring manual removal. It is very easy for personnel to fail to remove waste due to negligence or new employees. Furthermore, the fluidity of double-sided tape itself means that after manual removal of waste, glue threads are easily left at the edges, resulting in unqualified dimensions and appearance defects. The softer edges of foam or double-sided tape are easily damaged and squeezed, resulting in a poor appearance that cannot be used by customers, and high labor costs.

[0004] Therefore, the existing technology needs to be improved. Utility Model Content

[0005] In order to remedy the deficiencies of the prior art, the present application proposes a mold and a die-cutting machine with a waste removal function.

[0006] In the first aspect, the present invention provides a mold with a waste removal function, which adopts the following technical solutions:

[0007] A mold with a waste removal function comprises an upper cutting mold and a lower cutting mold, the upper cutting mold and the lower cutting mold are respectively arranged on an external frame, the upper cutting mold moves toward the lower cutting mold, a waste cleaning hole is provided on one side of the upper cutting mold, a cutting knife is provided at the edge of the hole on one side close to the lower cutting mold, a waste ejecting column is provided on the other side of the upper cutting mold, and the lower cutting mold is provided with a waste ejecting hole for the waste ejecting column to pass through, and the waste ejecting column is used to eject waste on the product from the waste ejecting hole.

[0008] By adopting the above technical solution, due to the setting of the waste ejector pin and the waste ejector hole, after the upper cutting die is used to punch and die-cut the product on the external frame, the product is pulled by the external machine so that the through hole produced by the punching faces the waste ejector hole, and then the waste ejector pin is passed through the through hole and the waste ejector hole by the upper cutting die. If there is still waste in the through hole, it will be ejected from the waste ejector hole by the waste ejector pin, which can avoid the waste remaining on the product and the need for manual waste removal, thereby achieving the simultaneous completion of machine die-cutting and waste discharge, reducing labor costs and improving product quality.

[0009] Preferably, the waste cleaning hole is arranged in a conical shape, and the portion of the waste cleaning hole with a smaller cross-sectional area is arranged close to the cutting knife.

[0010] By adopting the above technical solution, when the die-cutting machine performs through-hole processing on the product, the upper cutting die moves toward the lower cutting die until the cutting knife completely penetrates the product. At this time, the waste generated by the die-cutting product will be in the waste cleaning hole and will be taken away from the product by the upper cutting die through the friction between the waste and the side wall of the waste cleaning hole. After multiple die-cutting operations, the waste generated will be stacked in order in the waste cleaning hole. Since the waste cleaning hole is conical in design, when cleaning the waste in the waste cleaning hole, the waste can be more conveniently removed from between the waste cleaning holes, thereby facilitating the cleaning of the waste.

[0011] Preferably, the cross section of the top waste column is smaller than the cross section of the area enclosed by the cutting blade.

[0012] By adopting the above technical solution, since the cross-sectional area of ​​the waste column is smaller than the cross-sectional area of ​​the area enclosed by the cutting knife, and since the size of the cutting knife determines the size of the waste, the cross-sectional area of ​​the waste column is smaller than the cross-sectional area of ​​the waste. Then, when the external machine pulls the product so that the waste faces the waste hole, errors may occur due to precision issues. Therefore, setting the cross-sectional area of ​​the waste column smaller than the cross-sectional area of ​​the waste can allow partial errors in the product and avoid the waste column pushing out the required part of the product and causing damage to the product.

[0013] Preferably, the cross section of the top waste hole is larger than the cross section of the area enclosed by the cutting knife.

[0014] By adopting the above technical solution, since the cross-sectional area of ​​the waste hole is larger than the cross-sectional area of ​​the area enclosed by the cutting knife, the cross-sectional area of ​​the waste hole is larger than the cross-sectional area of ​​the waste material. Therefore, when the waste column pushes the waste material out of the waste hole, the waste material can be directly pushed out of the waste hole by the waste column, and the waste material will not be stuck on the inner wall of the waste hole, thereby facilitating the ejection of the waste material.

[0015] Preferably, the lower cutting die is provided with a positioning post, and the upper cutting die is provided with a positioning hole for the positioning post to pass through.

[0016] By adopting the above technical solution, the upper cutting die can always move along the length direction of the positioning column during the die-cutting process, so that the operation stability of the upper cutting die is better, and the cutting knife can be ensured to be always in the correct position during die-cutting, thereby reducing product waste.

[0017] In the second aspect, the utility model also provides a die-cutting machine adopting the following technical solution:

[0018] A die-cutting machine comprises the above-mentioned die.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. Due to the setting of the ejector pin and the ejector hole, after the upper cutting die is used to punch and die-cut the product on the external frame, the product is pulled by an external machine so that the through hole produced by the punching faces the ejector hole. The upper cutting die then passes the ejector pin through the through hole and the ejector hole. If there is still waste in the through hole, it will be ejected from the ejector hole by the ejector pin, which can avoid the waste remaining on the product and the need for manual waste removal. This achieves the simultaneous completion of machine die-cutting and waste removal, reduces labor costs, and improves product quality.

[0021] 2. Because the cross-sectional area of ​​the waste pin is smaller than the cross-sectional area of ​​the area enclosed by the cutting blade, and the size of the cutting blade determines the size of the waste, the cross-sectional area of ​​the waste pin is smaller than the cross-sectional area of ​​the waste. In this case, when the external machine pulls the product so that the waste faces the waste hole, errors may occur due to precision issues. Therefore, setting the cross-sectional area of ​​the waste pin smaller than the cross-sectional area of ​​the waste can allow for some errors in the product and avoid the waste pin pushing up the required part of the product and causing damage to the product.

[0022] 3. Because the cross-sectional area of ​​the top waste hole is larger than the cross-sectional area of ​​the area enclosed by the cutting knife, the cross-sectional area of ​​the top waste hole is larger than the cross-sectional area of ​​the waste material. Therefore, when the waste ejector column ejects the waste material from the top waste hole, the waste material can be directly ejected from the top waste hole by the waste ejector column, and the waste material will not be stuck on the inner wall of the top waste hole, so as to facilitate the ejection of the waste material.

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The embodiment of the present application discloses a mold with a waste removal function. Figure 1The mold includes an upper cutting die 1 and a lower cutting die 2. Specifically, the upper cutting die 1 and the lower cutting die 2 are respectively connected to the external frame. Under the action of the external frame, the upper cutting die 1 can move toward the direction of the lower cutting die 2 to realize the function of stamping and die cutting. A waste removal hole 11 is provided on the upper cutting die 1. The waste removal hole 11 is provided with a corresponding number according to the through holes to be processed by the product. The direction of the waste removal hole 11 is parallel to the vertical direction. At the same time, the cross-sectional shape of the waste removal hole 11 is adapted to the shape of the through hole processed by the product. A cutting knife 12 is provided on the upper cutting die 1. The cutting knife 1 2 is arranged on one side of the upper cutting die 1 close to the lower cutting die 2, and the cutting knife 12 is arranged around the edge of the opening of the waste hole 11, so that when the product is die-cut, the size of the waste generated is the same as the cross-section of the opening of the waste hole 11 close to the lower cutting die 2. In this embodiment, the waste hole 11 is arranged on one side along the moving direction of the product, and a waste pin 3 is arranged on the other side of the upper cutting die 1. The waste pin 3 is arranged on one side of the upper cutting die 1 close to the lower cutting die 2. The waste pin 3 is cylindrical. The number of the waste pins 3 is the same as the number of the waste holes 11. The axis of the column 3 is set parallel to the vertical direction, and a top waste hole 21 is set at the corresponding position of the lower cutting die 2. The top waste hole 21 is set corresponding to the position and number of the top waste column 3. The top waste hole 21 is used for inserting the top waste. When the external frame is punching and die-cutting the product, the product is pulled into the space between the upper cutting die 1 and the lower cutting die 2 by the external machine, and then the upper cutting die 1 is punched and moved toward the lower cutting die 2 by the frame, so that the cutting knife 12 cuts the product. At this time, the cut waste will be squeezed out from the waste clearing hole 11 under the action of stamping, and can be removed by manual or The other waste removal structures are moved out, and then the through hole processed in the product is moved to a position corresponding to the top waste hole 21 by an external machine through pulling up, down, left and right. At this time, the upper cutting die 1 is moved downward to insert the top waste column 3 into the top waste hole 21. In this design method, after the stamping and die-cutting are completed, the top waste column 3 is used to insert the processed through hole so that the extruded waste falls out of the top waste hole 21, which can avoid waste remaining on the product and requiring manual waste removal, and realizes the simultaneous completion of machine die-cutting and waste discharge, thereby reducing the cost of the processing process.

[0028] Viewed from the vertical direction, the thickness of the cutting blade 12 is much smaller than the length of the waste ejector column 3 , so when the waste ejector column 3 ejects the waste from the waste ejector hole 21 , the cutting blade 12 will not perform die-cutting on the product.

[0029] Reference Figure 1In order to better squeeze out the processed waste during the die-cutting process, the waste cleaning hole 11 is set to be conical, and the side of the waste cleaning hole 11 with a smaller cross-sectional area is set toward the lower cutting die 2. When the die-cutting process is performed, the waste generated will be accumulated in the waste cleaning hole 11. Since the waste cleaning hole 11 is designed to be conical, when taking out the waste, it can be taken out directly along the side wall of the waste cleaning hole 11, or it can be taken out through other material-taking structures, so that the cleaning of the waste is more convenient and simple.

[0030] Better yet, in this embodiment, the cross-section of the waste ejector column 3 is smaller than the cross-section of the area enclosed by the cutting knife 12, that is, the cross-section of the waste ejector column 3 is smaller than the cross-section of the waste material. Therefore, in the process of ejecting the waste material in the product, the product will be pulled by the action of an external machine. Due to precision issues, there will be some error between the waste material and the waste ejector hole 21 during the pulling process. Therefore, setting the cross-section of the waste ejector column 3 smaller than the cross-section of the waste material can allow the product to produce some error during the movement process, so as to avoid the waste ejector column 3 from damaging the required part of the product during the insertion into the waste ejector hole 21, thereby reducing product waste.

[0031] At the same time, the cross-section of the waste ejection hole 21 is set to be larger than the cross-section of the area surrounded by the cutting knife 12, that is, the cross-section of the waste ejection hole 21 is larger than the cross-section of the waste material. Therefore, when the waste ejection column 3 ejects the waste material from the waste ejection hole 21, the waste material can be directly ejected from the waste ejection hole 21 by the waste ejection column 3, and the waste material will not be stuck on the inner wall of the waste ejection hole 21, thereby facilitating the ejection of the waste material.

[0032] In addition, in this embodiment, a positioning column 4 is provided on the lower cutting die 2. The positioning column 43 is in the shape of a cylindrical rod, and the positioning column 4 is integrally arranged on the lower cutting die 2. At the same time, a positioning hole 13 is provided at the corresponding position of the upper cutting die 1. The positioning hole 13 is used for the positioning column 4 to pass through, and the positioning column 4 is set to a pointed end at the part close to the upper cutting die 1. In order to make the upper cutting die 1 run more stably, a plurality of positioning columns 4 are provided, and the positioning holes 13 are set corresponding to the positioning columns 4. The positioning columns 4 are evenly distributed at the edges of the lower cutting die 2 so that the upper cutting die 1 always moves along the length direction of the positioning columns 4 during the die-cutting process, so that the upper cutting die 1 is accurately positioned and has good stability, thereby reducing product waste.

[0033] The implementation principle of a mold with a waste removal function in an embodiment of the present application is as follows: after the upper cutting die 1 is used to punch and die-cut the product on an external frame, the product will be pulled up, down, left and right by an external machine so that the through hole on the product corresponds to the top waste hole 21. Then the upper cutting die 1 will move toward the lower cutting die 2 so that the top waste column 3 is inserted into the top waste hole 21. If there is waste remaining in the through hole processed by the product, it will be ejected from the top waste hole 21 by the top waste column 3, thereby realizing the simultaneous completion of machine die-cutting and waste removal, reducing labor costs and improving product quality.

[0034] The present invention also provides a die-cutting machine, comprising the above-mentioned die-cutting mechanism. The die-cutting machine of this embodiment also has the above-mentioned beneficial effects, which will not be described in detail here.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
