They are widely used in the fields of optics and optoelectronics technology and play an important role in many industries with their unique optical properties and functions. In the processing of optical film rolls, in order to efficiently utilize materials and reduce waste, it is necessary to make two die molds with different material widths, including X arrangement and Y arrangement, to flexibly match the consumed materials. For example, when the width of the raw material is 1000 mm, the material width of the X arrangement is 400 mm, and the material width of the Y arrangement is 600 mm. Such a combination can ensure the full utilization of materials and avoid stagnation.

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model will be further described below with reference to the embodiments.

[0022] Embodiment: Referring to Figures 1 to 3 , a die holder for flexibly fixing a die, comprising a frame body 1. Two cavities 2 are provided inside the frame body 1. Partition plates 3 are fixedly connected between the inner walls of the two cavities 2. Two flexible fixing mechanisms are provided. The flexible fixing mechanism includes two moving components, a fixing component and a synchronous component. The moving component includes a threaded rod 4 rotatably connected to the upper surface of the partition plate 3 through a bearing. The threaded rod 4 passes through and is rotatably connected to the upper surface of the frame body 1 through a bearing. A nut 5 is threadedly connected to the threaded rod 4. The fixing component includes limiting through grooves 6 provided between the inner walls on both sides of the frame body 1 and the two cavities 2. Connecting blocks 7 are slidably connected in the two limiting through grooves 6. The side walls of the two connecting blocks 7 are respectively fixedly connected to the side walls of the two nuts 5. A fixing plate 8 is fixedly connected between the adjacent side walls of the two connecting blocks 7. Among the two threaded rods 4 in the flexible fixing mechanism, the top end of any one of them is fixedly connected to a rotating handle 12, which is convenient for the staff to operate. Two handles 13 are fixedly connected to the front surface of the frame body 1, which is convenient for taking the frame body 1. The two flexible fixing mechanisms are symmetrically arranged with respect to the two partition plates 3.

[0023] The synchronous component includes a housing 9 fixedly connected to the upper surface of the frame body 1. Synchronous pulleys 10 are fixedly connected to the circumferences of the two threaded rods 4. A synchronous belt 11 is engaged between the two synchronous pulleys 10. The synchronous belt 11 and the two synchronous pulleys 10 are both located inside the housing 9. The two threaded rods 4 in the flexible fixing mechanism both pass through and are rotatably connected to the upper surface of the housing 9 through bearings.

[0024] The working principle of the present utility model is as follows: When in use, place the required die mold into the frame body 1, and then move the upper and lower fixing plates 8 according to the specific length of the die mold to clamp it tightly. Now, only one die mold is needed instead of the two die molds arranged in X and Y patterns as originally required. During subsequent use, direct transformation can be carried out. When transforming, only need to rotate the die mold by 90 degrees and then fix it again. The number of die molds manufactured is reduced, the cost is controlled, and the product profit is indirectly increased. During the fixing process, control the movement of the two fixing plates 8 to clamp and fix the die mold between them. Here, a flexible fixing mechanism is taken as an example. When fixing is required, rotate the threaded rod 4 by turning the handle 12. When the threaded rod 4 rotates, it will drive the synchronous pulley 10 to rotate. Then, through the meshing transmission of the synchronous belt 11, another synchronous pulley 10 is driven to rotate, thereby driving the threaded rod 4 of another moving component to rotate. The two threaded rods 4 rotate synchronously. The two nuts 5 are respectively restricted by the two limit through slots 6 and the connecting blocks 7, and will respectively engage with the two threaded rods 4 in a threaded manner. Then, the two nuts 5 will move synchronously up and down along the two threaded rods 4, and drive the fixing plate 8 to move through the two connecting blocks 7. Furthermore, the clamping and fixing of the die mold is realized through the two flexibly movable fixing plates 8.

[0025] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present utility model.
