Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a base plate making mold for a micro-nano optical embossing plate. Background Art

[0002] With the development of packaging and printing technology, mid-to-high-end products have higher and higher requirements for the presentation form, graphic content, and anti-counterfeiting of packaging products. Compared with commonly used packaging materials, dynamic and three-dimensional display anti-counterfeiting packaging materials have attracted great attention from the industry due to their advantages such as good anti-counterfeiting effect, high difficulty in imitation, and good visual effect. The three-dimensional anti-counterfeiting efficiency is currently achieved by preparing micro-nano structures on paper. At present, the preparation of micro-nano structures is mostly achieved by molding rollers. However, the molding rollers need to be laser engraved and electroplated first, and the laser engraving plate is expensive, and the overprinting accuracy is difficult to control during molding.

[0003] According to research, making micro-nano structures on nickel plates and using embossing can not only solve the problem of overprinting accuracy, but also has low cost. However, due to the poor uniformity of the electroplated thickness of the nickel plate, it is difficult to control the flatness during embossing. Therefore, it is necessary to make a matching base plate for the nickel plate to ensure the flatness during embossing. At present, all injection molding processes are in-mold molding processes, such as the application number CN201010226750.2, entitled "Method for Making Holographic Images on In-Mold Injection Molded Products", which injects molten plastic into a mold cavity composed of a female mold and a male mold to form a holographic molded image. After the product is formed, a holographic molded image is formed at the position of the product outer surface corresponding to the holographic molded nickel plate. However, the base plate size of the mold molding cannot be changed, and the base plate can only be made according to the fixed nickel plate. The mold has poor versatility, resulting in different nickel plates requiring the customization of different molds, which directly increases the production of printing companies.

[0004] Therefore the prior art still needs to be improved and enhanced. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] It should be noted that when a component is referred to as being "mounted on", "fixed on" or "disposed on" another component, it may be directly on the other component or there may be an intermediate component at the same time. When a component is referred to as being "connected to" another component, it may be directly connected to the other component or there may be an intermediate component at the same time.

[0027] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of the present invention are merely relative concepts or are based on the normal use status of the product and should not be considered as restrictive.

[0028] See also Figure 1 and Figure 2 The utility model provides a micro-nano optical embossing plate base plate making mold comprising a bottom mold plate 1, a left mold component 2, a right mold component 3, a front mold component 4, a rear mold component 5 and a top mold component 6. The right mold component 3, the front mold component 4, the left mold component 2 and the rear mold component 5 are sequentially arranged on the bottom mold plate 1 to form a square mold cavity (such as Figure 1 As shown), the top mold assembly 6 is arranged on the bottom mold plate 1 and can be raised and lowered relative to the bottom mold plate 1.

[0029] The right mold assembly 3 pushes the front mold assembly 4 to move toward the left mold assembly 2 to adjust the length of the square, and the left mold assembly 2 drives the front mold assembly 4 to move toward the rear mold assembly 5 to adjust the width of the square (such as Figure 2 As shown), the size of the square can be adjusted by the right mold component 3 and the left mold component 2, so that the plate-making mold can be freely adjusted according to the size of the nickel plate to increase the versatility of the plate-making mold. After the size is adjusted, the top mold component 6 is controlled to descend so that it is in close contact with the top surfaces of the right mold component 3, the front mold component 4, the left mold component 2 and the rear mold component 5, and then the resin is injected. After cooling and demolding, the initial shaping of the nickel plate is completed, so that the size of the membrane cavity used for molding can be adjusted as needed, which improves the versatility of the plate-making mold and reduces the plate-making cost.

[0030] Please also read Figure 3 and Figure 4 In the base plate making mold of the micro-nano optical embossing plate provided by the utility model, the rear end of the right mold component 3 abuts against the rear mold component 5 to achieve the longitudinal positioning of the right mold component 3, so that the right mold component 3 can only move (such as translate) laterally (i.e., to the left or to the right) along the rear mold component 5.

[0031] Specifically, the right mold assembly 3 includes a right mold plate 31, a right mold control module 32 and a right mold groove rail (not shown in the figure). The right mold control module 32 is arranged at the rear end of the right mold plate 31 and is penetrated in the rear mold assembly 5. The right mold control module 32 is connected to the right mold plate 31. The right mold groove rail is located on the inner side of the right mold plate 31. The right mold control module 32 controls the lateral movement of the right mold plate 31 so that the length of the platemaking mold can be adjusted. Moreover, the right mold control module 32 is arranged in the rear mold assembly 5, so that the right mold plate 31 can be tightly fitted with the rear mold assembly 5 without generating a gap, so as to prevent the resin from flowing out during the injection molding process.

[0032] The left end of the rear mold assembly 5 abuts against the left mold assembly 2 so that when the left mold assembly 2 moves longitudinally (ie, forward or backward), it will not interfere with the rear mold assembly 5.

[0033] Specifically, the rear mold assembly 5 includes a rear mold template 51, a rear mold groove 52 and a rear mold slider (not numbered in the figure). The rear mold template 51 is fixedly set on the bottom mold template 1. The rear mold template 51 is provided with a mounting hole (not numbered in the figure) for inserting the right mold control module 32. One end of the right mold control module 32 extends out of the outside of the rear mold template 51. The rear mold slider is set at the left end of the rear mold template 51 and is connected to the left mold assembly 2. When the left mold assembly 2 moves longitudinally, the rear mold slider plays an auxiliary positioning role, thereby causing the left mold assembly 2 to move along the left end of the rear mold template 51 so that no gap is generated between the two to prevent the resin from flowing out during the injection molding process.

[0034] The depth of the mounting hole is greater than the telescopic length of the right mold screw 321, so that it will not limit the telescopic length of the right mold screw 321, that is, the right mold plate 31 can be as close to the left mold plate 21 as possible, so as to be suitable for smaller nickel plates.

[0035] Optionally, the right mold control module 32 includes a right mold screw 321, a right mold slider 322, a right mold screw handle 323 and a right mold screw fixing block 324, the right mold screw 321 is inserted into the rear mold plate 51, the right mold slider 322 is fixed on the right mold screw 321 and placed in the rear mold plate 51, the rear mold groove 52 is for the right mold slider 322 to slide, and one end of the right mold slider 322 extends out and is connected to the right mold plate 31, the right mold screw fixing block 324 is sleeved on one end of the right mold screw 321 and fixed on the bottom mold plate 1, and the right mold screw handle 323 is arranged at the end of the right mold screw 321.

[0036] During installation, the right mold screw rod fixing block 324 is used to fix one end of the right mold screw rod 321, and the right mold slider 322 is used to position the middle part of the right mold screw rod 321. Furthermore, a limiting member 325 is sleeved on the other end of the right mold screw rod 321, so that when the right mold screw rod 321 is extended or retracted, the limiting member 325 moves along the installation hole to assist the extension and retraction of the right mold screw rod 321, and can also prevent the right mold screw rod 321 from escaping from the right mold slider 322, and also make the two ends of the right mold screw rod 321 located on the same straight line, so that the right mold plate 31 can move smoothly horizontally.

[0037] When in use, the right mold screw 321 is rotated synchronously by controlling the right mold screw handle 323 to rotate forward and reversely, and the right mold slide block 322 can only move left and right by utilizing the limiting effect of the rear mold groove rail 52, thereby driving the right mold plate 31 to move left and right.

[0038] Furthermore, the length of the rear mold groove 52 is smaller than the telescopic length of the right mold screw 321, so that the rear mold groove 52 serves to limit the extension length of the right mold screw 321, avoiding the possibility of deformation of the right mold screw 321 caused by the limiting member 325 abutting the bottom of the mounting hole, and by increasing the spacing between the rear mold groove 52 and the rear mold slider, the connection strength between the rear mold slider and the rear mold plate 51 is made stronger, avoiding the deformation of the rear mold slider causing a gap between the left mold assembly 2 and the rear mold plate 51.

[0039] Please also read Figure 5 The front end of the left mold assembly 2 abuts against the front mold assembly 4, so that when the front mold assembly 4 moves to the left, the left mold assembly 2 will not interfere with the front mold assembly 4.

[0040] Specifically, the left mold assembly 2 includes a left mold template 21, a left mold slider 22, a left mold control module 23 and a left mold groove rail 24. The left mold slider 22 is arranged at the front end of the left mold template 21, and the left mold control module 23 is arranged at the rear end of the left mold template 21 and is located on the outside of the left mold template 21. The left mold control module 23 is connected to the left mold template 21, and the rear mold slider is placed in the left mold groove rail 24 to slide. When the left mold template 21 moves backward, the rear groove slider moves from the left mold groove rail 24 to assist the left mold template 21 to move smoothly. At the same time, it also plays a role in stabilizing the left mold template 21 to avoid shaking of the left mold template 21 during movement or a gap between the left mold template 21 and the rear mold template 51.

[0041] Furthermore, by arranging the left mold control module 23 on the outside of the left mold plate 21, it does not interfere with the left mold plate 21 or the rear mold plate 51 during the process of controlling the left mold plate 21 to move forward or backward.

[0042] Specifically, the left mold control module 23 includes a left mold screw 231, a left mold screw fixing block 232, a left mold screw sleeve 233, a vertical bevel gear 234, a horizontal bevel gear 235, a rotating shaft 236, a rotating shaft fixing frame 237, a rotating shaft crank 238 and a left mold screw arm 239, wherein the left mold screw arm 239 is arranged at the rear end of the left mold screw 231 and is connected to the left mold plate 21, the left mold screw sleeve 233 is sleeved on the left mold screw 231 and is connected to the left mold screw fixing block 232, the left mold screw fixing block 232 is fixed on the bottom mold plate 1, the vertical bevel gear 234 is sleeved on the left mold screw 231, the horizontal bevel gear 235 is arranged on the rotating shaft 236 and meshes with the vertical bevel gear 234, the rotating shaft 236 is fixed to the bottom mold plate 1 through the rotating shaft fixing frame 237, and the rotating shaft crank 238 is arranged at the end of the rotating shaft 236.

[0043] Preferably, the length of the left mold screw 231 is not longer than the left mold plate 21, and the distance between the left mold screw arm 239 and the left mold screw sleeve 233 is not less than the size difference between the maximum and minimum nickel plates that the plate making mold can adjust to place.

[0044] During installation, the left mold screw rod sleeve 233 is sleeved on the left mold screw rod 231, and then welded to the left mold screw rod fixing block 232, so as to fix the middle part of the left mold screw rod 231, and then the left mold screw rod arm 239 is connected to one end of the left mold screw rod 231 and the left mold plate 21, so that the left mold screw rod 231 is fixed, and the rotating shaft fixing frame 237 also plays the role of positioning the rotating shaft 236, so that the horizontal bevel gear 235 on the rotating shaft 236 is meshed with the vertical bevel gear 234 on the left mold screw rod 231. During use, by rotating the rotating shaft crank 238 forward and reverse, the horizontal bevel gear 235 is rotated synchronously, so as to drive the vertical bevel gear 234 to rotate synchronously, and then the left mold screw rod 231 is controlled to extend and retract forward and backward, so that the left mold plate 21 moves forward and backward along with the extension and retraction of the left mold screw rod 231.

[0045] The right end of the front mold assembly 4 is in contact with the right mold assembly 3, so that when the right mold assembly 3 moves to the left, it can push the front mold assembly 4 to move synchronously, and the length of the plate-making mold can be adjusted. Specifically, the front mold assembly 4 includes a front mold plate 41, a front mold groove rail, and a front mold slider 43. The front mold slider 43 is arranged at the right end of the front mold plate 41 and slides in the right mold groove rail. Through the connection between the front mold slider 43 and the right mold groove rail, the front mold plate 41 can move synchronously with the left and right movement of the right mold plate 31.

[0046] Optionally, the front mold groove is located on the inner side of the front mold plate 41, and the left mold slider 22 is placed in the front mold groove to slide. Through the connection between the left mold slider 22 and the front mold groove, the front mold plate 41 can move synchronously with the forward and backward movement of the left mold plate 21. The front mold plate 41 can be controlled to adjust its position forward, backward, left and right through the left mold plate 21 and the right mold plate 31, thereby achieving the function of adjusting the size of the platemaking mold.

[0047] Please continue reading Figure 1 and Figure 2 The top mold assembly 6 includes a top mold plate 61, a top mold stand 62, a top mold screw rod 63, a top mold screw rod rocker 64, a top mold slide rail 65 and a top mold slider 66.

[0048] During installation, the top mold stand 62 plays the role of positioning the top mold screw rod 63, and then the top mold slider 66 connects the top mold screw rod 63 and the top mold plate 61, so that the top mold plate 61 can rise and fall with the extension and contraction of the top mold screw rod 63, and the top mold slide rail 65 plays the role of limiting the top mold slider 66, so that the top mold slider 66 can only move up and down, and the top mold slider 66 can move smoothly. During use, the top mold screw rod 63 is rotated synchronously by the forward and reverse rotation of the top mold screw rod rocker 64, so as to drive the top mold slider 66 on the top mold screw rod 63 to move up and down synchronously, thereby controlling the lifting and lowering of the top mold plate 61 connected to the top mold slider 66.

[0049] In this embodiment, the top mold plate 61 is provided with a resin injection hole 611 and an exhaust hole 612, through which injection molding can be performed in the plate-making mold, and the exhaust hole 612 is used to exhaust the air in the plate-making mold during the injection molding process. Since injection molding is a prior art, it is not described here in detail. In this embodiment, the resin injection hole 611 and the exhaust hole 612 are located at the upper left corner of the top mold plate 61, so that when the plate-making mold is adjusted to the minimum size, the resin injection hole 611 and the exhaust hole 612 are always located above the plate-making mold, so that resin can be smoothly injected into the plate-making mold and air can be exhausted.

[0050] The inner sides of the rear template 51 , the left template 21 , the right template 31 , the front template 41 and / or are provided with scales 7 , and the scales 7 are located above each groove rail. The scales 7 enable the operator to ensure that the nickel plate is placed flat relative to the bottom template 1 .

[0051] The base plate making mold of the micro-nano optical embossing plate also includes a casting component (not shown in the figure), a guide component (not shown in the figure), a demolding component (not shown in the figure), etc., to assist the plate making mold to complete the plate making. Since the casting component, guide component, and demolding component are existing technologies, they will not be repeated here.

[0052] In order to make the scheme of the base plate making mold of the micro-nano optical embossing plate provided by the present invention clearer, the operation steps of the base plate making mold of the micro-nano optical embossing plate are described in detail below:

[0053] S1. Place the nickel plate face down on the bottom template 1 of the plate-making mold, and position one corner of the nickel plate at the upper left inner corner of the plate-making mold, that is, place the adjacent two sides of the nickel plate close to the rear template 51 and the left template 21 of the plate-making mold respectively.

[0054] S2. Manually shake the right mold screw handle 323 in the right mold assembly 3, and the right mold screw 321 rotates to drive the right mold slider 322 and the right mold plate 31 to move horizontally to the left as a whole. At the same time, the front mold plate 41 moves horizontally to the left synchronously with the relative movement of the left mold slider 22 and the front mold groove rail until the inner side surface of the right mold plate 31 contacts and fits with the nickel plate.

[0055] S3. Manually shake the rotating shaft crank 238 in the left mold assembly 2, and convert the horizontal circumferential rotation of the rotating shaft 236 into the vertical circumferential rotation of the left mold screw 231 through the vertical engagement of the horizontal bevel gear 235 and the vertical bevel gear 234. The rotation of the left mold screw 231 drives the left mold screw arm 239 and the left mold plate 21 to move backward horizontally as a whole. At the same time, the front mold plate 41 moves backward horizontally synchronously with the relative movement of the front mold slider 43 and the right mold groove rail until the rear side of the front mold plate 41 contacts and fits with the nickel plate.

[0056] S4. Visually inspect and ensure that the nickel plate is level with respect to the bottom template 1 according to the rear mold scale 7 and the left mold scale 7, and then manually and slowly shake the right mold screw handle 323 and the shaft handle 238 in sequence, so that the four sides of the nickel plate are respectively in close contact with the inner sides of the front, rear, left and right templates 31.

[0057] S5. Manually shake the top mold screw handle 64 in the top mold assembly 6, and the top mold screw 63 rotates to drive the top mold slider 66 and the top mold assembly 6 to move downward vertically as a whole, until the bottom surface of the top mold plate 61 in the top mold assembly 6 is in close contact with the top surfaces of the front, rear, left and right mold plates. At this point, the top mold plate 61, the front, rear, left and right mold plates and the nickel plate are assembled together to form the injection molding inner cavity of the plate making mold.

[0058] S6. Resin base plate injection molding: first, polymer resin particles or powder are loaded into the injection molding machine hopper, and the hopper screw pushes the plastic to a fully molten state in the heat pipe; then, the temperature, pressure and speed of the injection molding machine are adjusted to push the molten plastic into the entire plate-making mold cavity; then, the molten plastic is cooled and solidified. After the molten plastic is injected into the mold cavity, the injection molding machine stops applying pressure and controls the cooling time and the temperature of the cooling medium to ensure that the molten plastic is fully cooled and solidified and bonded to the nickel plate; then, demolding is performed. When demolding, the plate-making mold is first controlled to vibrate (not shown), and then the top mold screw handle 64, the shaft handle 238, and the right mold screw handle 323 are manually shaken in the opposite direction in turn to open the plate-making mold, and the cooled and solidified resin base plate together with the bonded nickel plate are removed from the plate-making mold.

[0059] S7. Molding of the micro-nano embossing plate: The resin base plate bonded to the nickel plate is subjected to secondary processing, the excess burr resin is polished, and holes are punched and screws are tightened in the non-micro-nano structure graphic areas at the four corners of the nickel plate surface to reinforce the nickel plate and the resin base plate, so that the micro-nano embossing plate is molded.

[0060] To sum up, the utility model can adjust the size of the square through the right mold assembly and the left mold assembly, so that the platemaking mold can be freely adjusted according to the size of the nickel plate to increase the versatility of the platemaking mold. After the size is adjusted, the top mold assembly is controlled to descend so that it is in close contact with the top surfaces of the right mold assembly, the front mold assembly, the left mold assembly and the rear mold assembly, and then the resin is injected. After cooling and demolding, the initial shaping of the nickel plate is completed, so that the size of the membrane cavity used for molding can be adjusted according to needs, which improves the versatility of the platemaking mold and reduces the platemaking cost.

[0061] In addition, the utility model has the characteristics of simple structure, easy operation, strong applicability, etc.
