Description

Technical Field

[0001] This utility model relates to the field of optical functional film preparation, and in particular to a molding die for optical functional film preparation. Background Technology

[0002] Optical functional films are thin-film materials with specific optical properties used to control the characteristics of light propagation. Through scientific and precise design of material structure and composition, they can accurately control the reflection, transmission, absorption, polarization, and phase characteristics of light. For example, antireflective films reduce light reflection from the surface of optical components, increasing light transmittance, and are commonly found in camera lenses; reflective films efficiently reflect specific wavelengths of light and are used in display backlight modules; polarizing films allow only light polarized in a specific direction to pass through, and are crucial in 3D displays and liquid crystal displays. Their performance depends on material selection, film thickness, and manufacturing processes, and they are widely used in industries such as display, lighting, photovoltaics, and imaging, forming the cornerstone of the modern optoelectronic industry. Furthermore, molding dies are indispensable in the fabrication of optical functional films, facilitating precise molding.

[0003] However, in the existing technology, after the optical functional film completes the molding process in the mold, it needs to be removed from the mold cavity by workers with the help of external tools to achieve the purpose of demolding, which will undoubtedly affect the production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a molding die for preparing optical functional films, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a molding die for preparing optical functional films, comprising an operating table, an adjustment groove inside the operating table, a first electric push rod inside the adjustment groove, a movable plate fixedly connected to the upper end of the first electric push rod, a support rod fixedly connected to the upper end of the movable plate, a push plate fixedly connected to the other end of the support rod, a connecting rod fixedly connected to the upper edge of the movable plate, a ball bearing inside the connecting rod, and a lower mold located at the upper center of the operating table.

[0006] Preferably, the two sides of the operating table are fixedly connected to support plates, the upper end of the support plate is provided with a second electric push rod, the other end of the second electric push rod is fixedly connected to a short block, one side of the short block is fixedly connected to a top plate, the lower end of the top plate is provided with an upper mold, and the upper end of the top plate is provided with a pouring nozzle.

[0007] Preferably, pressure plates are fixedly connected to both sides of the top plate, a fixing block is fixedly connected to the front side of the operating table, a buffer groove is provided inside the fixing block, a short plate is fixedly connected inside the buffer groove, a slide rod is slidably connected inside the short plate, a connecting plate is fixedly connected to the upper end of the slide rod, a spring is provided on one side of the connecting plate, a pressure rod is fixedly connected to the other side of the connecting plate, a long plate is fixedly connected to the upper end of the pressure rod, and a damping rod is provided at the lower end of the interior of the fixing block.

[0008] Preferably, the movable plate slides inside the adjustment groove via a first electric push rod.

[0009] Preferably, the number of the second electric push rods is multiple, and they are symmetrically arranged about the center line of the operating table.

[0010] Preferably, the slide bar slides inside the short plate via a connecting plate, a damping rod, and a spring.

[0011] Using the above technical solution, by activating the first electric push rod, the moving plate moves upward under its drive, and the push plate slides out from inside the lower mold. At this time, the formed film is pushed out of the lower mold, realizing demolding. Similarly, by retracting the first electric push rod, the moving plate drives the push plate to slide back into the lower mold and return to its position, ready for the next use. In addition, the two sets of connecting rods are equipped with ball bearings. The ball bearings can greatly improve the smoothness of the push plate sliding in the lower mold. The position of the push plate can be adjusted by the components such as the first electric push rod, the moving plate, the connecting rod, and the ball bearings, thereby pushing out the formed film, speeding up demolding, and improving production efficiency.

[0012] Using the above technical solution, during the mold closing process of the upper and lower molds, the top plate causes the pressure plate to squeeze the long plate, while the long plate causes the connecting plate to move downward. At this time, the slide rod slides inside the short plate, and the connecting plate simultaneously compresses the spring and damping rod. The spring accumulates elastic potential energy. After the diaphragm is formed, the top plate releases the downward pressure and moves upward. The spring quickly rebounds and pushes the connecting plate and the long plate to reset in the opposite direction. The resulting elastic reaction force acts in the opposite direction on the top plate, providing it with additional upward driving force, thereby accelerating the process of the top plate leaving the mold. Through components such as the fixed block, spring, damping rod, and short plate, the rising time of the top plate can be effectively shortened, significantly improving the mold opening efficiency, while also ensuring continuous production.

Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Example 1

[0021] Please see Figures 1-5 This utility model provides a technical solution: a molding die for preparing optical functional films, including an operating table 1, an adjustment groove 2 inside the operating table 1, a first electric push rod 3 inside the adjustment groove 2, a movable plate 4 fixedly connected to the upper end of the first electric push rod 3, a support rod 5 fixedly connected to the upper end of the movable plate 4, a push plate 6 fixedly connected to the other end of the support rod 5, a connecting rod 7 fixedly connected to the upper edge of the movable plate 4, a ball bearing 8 inside the connecting rod 7, a lower mold 9 at the upper middle part of the operating table 1, support plates 10 fixedly connected to both sides of the operating table 1, a second electric push rod 11 at the upper end of the support plate 10, a short block 12 fixedly connected to the other end of the second electric push rod 11, a top plate 13 fixedly connected to one side of the short block 12, an upper mold 15 at the lower end of the top plate 13, a pouring nozzle 14 at the upper end of the top plate 13, and the movable plate 4 sliding inside the adjustment groove 2 via the first electric push rod 3.

[0022] Specifically, the first electric push rod 3 is activated, and under its drive, the moving plate 4 moves upward, while the push plate 6 slides out from inside the lower mold 9. At this time, the formed film is pushed out of the lower mold 9, achieving demolding. Similarly, the first electric push rod 3 is retracted, and the moving plate 4 drives the push plate 6 to slide back into the lower mold 9 and return to its position, waiting for the next use. In addition, the two sets of connecting rods 7 are equipped with ball bearings 8. The ball bearings 8 can greatly improve the smoothness of the push plate 6 sliding in the lower mold 9. The position of the push plate 6 can be adjusted by the components such as the first electric push rod 3, the moving plate 4, the connecting rods 7, and the ball bearings 8, thereby pushing out the formed film, speeding up demolding, and improving production efficiency.

[0023] Example 2

[0024] Please see Figures 1-5 This utility model provides a technical solution: a molding die for preparing optical functional films. Pressure plates 16 are fixedly connected to both sides of the top plate 13. A fixing block 17 is fixedly connected to the front side of the operating table 1. A buffer groove 18 is provided inside the fixing block 17. A short plate 19 is fixedly connected inside the buffer groove 18. A sliding rod 20 is slidably connected inside the short plate 19. A connecting plate 21 is fixedly connected to the upper end of the sliding rod 20. A spring 22 is provided on one side of the connecting plate 21. A pressure rod 23 is fixedly connected to the other side of the connecting plate 21. A long plate 25 is fixedly connected to the upper end of the pressure rod 23. A damping rod 24 is provided at the lower end of the fixing block 17. Multiple sets of second electric push rods 11 are symmetrically arranged about the centerline of the operating table 1. The sliding rod 20 slides inside the short plate 19 through the connecting plate 21, the damping rod 24, and the spring 22.

[0025] Specifically, during the mold closing process of the upper mold 15 and the lower mold 9, the top plate 13 causes the pressure plate 16 to press against the long plate 25, while the long plate 25 causes the connecting plate 21 to move downward. At this time, the slide rod 20 slides within the short plate 19, and the connecting plate 21 simultaneously compresses the spring 22 and the damping rod 24. The spring 22 accumulates elastic potential energy. After the diaphragm is formed, the top plate 13 releases the downward pressure and moves upward. The spring 22 quickly rebounds and pushes the connecting plate 21 and the long plate 25 to reset in the opposite direction. The resulting elastic reaction force acts in the opposite direction on the top plate 13, providing it with additional upward driving force, thereby accelerating the process of the top plate 13 leaving the mold. Through components such as the fixed block 17, spring 22, damping rod 24, and short plate 19, the rising time of the top plate 13 can be effectively shortened, significantly improving the mold opening efficiency, while also ensuring continuous production.

[0026] Working principle: When using this molding die, firstly, the second electric push rod 11 is activated. Under its driving action, the second electric push rod 11 drives the top plate 13 to move downward, so that the upper mold 15 and the lower mold 9 are precisely fitted. Then, high-temperature solution raw material is injected into the mold through the pouring nozzle 14, and left to stand for the raw material to complete molding. After the molding process is completed, the second electric push rod 11 is activated again to drive the top plate 13 to move upward. Finally, the first electric push rod 3 is activated. Under its driving action, the moving plate 4 moves upward, and the push plate 6 slides out from the inside of the lower mold 9. At this time, the molded film is pushed out of the lower mold 9, realizing demolding. Similarly, the first electric push rod 3 is retracted, and the moving plate 4 drives the push plate 6 to slide back into the lower mold 9 and return to its position, waiting for the next use. In addition, the two sets of connecting rods 7 are equipped with ball bearings 8. The ball bearings 8 can greatly improve the smoothness of the push plate 6 sliding in the lower mold 9. The components such as plate 4, connecting rod 7, and ball bearing 8 can adjust the position of push plate 6, thereby pushing out the formed film, accelerating demolding, and improving production efficiency. During the mold closing process of upper mold 15 and lower mold 9, top plate 13 causes pressure plate 16 to squeeze long plate 25, and long plate 25 causes connecting plate 21 to move downward. At this time, slide rod 20 slides in short plate 19, and connecting plate 21 simultaneously compresses spring 22 and damping rod 24. Spring 22 accumulates elastic potential energy. After the film is formed, top plate 13 releases the downward pressure and moves upward. Spring 22 quickly rebounds and pushes connecting plate 21 and long plate 25 to reset in the opposite direction. The resulting elastic reaction force acts in the opposite direction on top plate 13, providing it with additional upward driving force, thereby accelerating the process of top plate 13 leaving the mold. The components such as fixing block 17, spring 22, damping rod 24, and short plate 19 can effectively shorten the rising time of top plate 13, significantly improve mold opening efficiency, and ensure continuous production.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
