Description

Technical Field

[0001] The utility model belongs to the technical field of optical lens compression molding, and particularly relates to a free spherical optical lens compression molding machine. Background Art

[0002] Free-sphere optical lenses are optical lenses with complex and unique surface designs, which have successfully broken through the limitations of traditional spherical lenses. Their surface shapes are not simple spheres, but are carefully designed and precisely calculated to achieve more excellent optical performance. Such lenses can be customized according to different needs and application scenarios. For example, the surface shape can be accurately shaped according to the wearer's vision, eye habits, frame shape, and specific optical requirements. Free-sphere optical lenses can effectively reduce aberrations and distortions, significantly improve the clarity and accuracy of imaging, and thus bring the wearer a wider, clearer, and more comfortable visual experience. Whether in the field of eyeglasses to correct vision, or in the fields of optical instruments and photographic equipment, free-sphere optical lenses play a vital role, fully satisfying people's unremitting pursuit of high-quality optical effects.

[0003] At present, in the production and processing flow of free spherical optical lenses, optical lens molding machines are usually used to assist in the molding process. The Chinese patent with the announcement number "CN212795624U" discloses an aspherical optical lens molding machine, which includes a movable plate and a base. The aspherical optical lens molding machine is configured with a forward and reverse motor. When the forward and reverse motor is started during use, the output shaft of the forward and reverse motor rotates to drive the screw to rotate, so that the movable block moves in the relative direction, and the fixed block and the connecting column also move accordingly. When the connecting column is moved to the groove, the upper mold and the lower mold are fixed at this time, and the hydraulic rod is started. The hydraulic rod pushes the movable plate downward, so that the upper mold and the lower mold fit closely. When the mold needs to be cleaned or replaced after use, it is only necessary to start the forward and reverse motor again to reverse. Similarly, the connecting column is moved out of the groove, and the upper mold and the lower mold can be removed. This makes the operation simpler, greatly improves the work efficiency, and successfully solves the problem of cumbersome disassembly and assembly of the current molding machine on the market.

[0004] However, during the production and processing of the above-mentioned device, a motor and a screw are used to achieve the locking and fixation of the mold. During the overall use process, it relies on the motor and the screw for clamping, and the overall cost is quite high. It is necessary to additionally set up components such as screws and motors. During the overall use period, two additional sets of motor screws and other structures are required, and the cost during use is relatively high. At the same time, it requires additional motor circuits and other structures, and the overall application is relatively complicated, so it needs to be improved. Utility Model Content

The bottom rail 8 on the base 7 at the top of the substrate 1 provides a stable installation and sliding basis for the lower slide 9 and the lower mold 10. It is particularly worth mentioning that the clamping mechanism 6 located in the middle of the top rear side of the substrate 1 can firmly install the upper slide 5 on the inner side of the top rail 4 and the lower slide 9 on the inner side of the bottom rail 8, ensuring that during the molding process, the positions of the upper mold 11 and the lower mold 10 are accurate and stable, thereby effectively improving the quality and precision of the lens molding, and ensuring the stability and reliability of production. During the processing, the telescopic cylinder 3 can be used to push the upper mold 11 and the lower mold 10 to close each other, and then the molding process can be carried out.

[0025] refer to Figure 1-Figure 5The clamping mechanism 6 includes a mounting rail 61, which is fixedly mounted in the middle of the top rear side of the substrate 1. Limiting components 62 are arranged on both sides of the interior of the mounting rail 61. A linkage component 63 is arranged on the top of the limiting component 62. The limiting component 62 includes a limiting spring 621 and a limiting hole 622. The limiting hole 622 is opened on the rear side of the upper slide plate 5 and the lower slide plate 9. The limiting spring 621 is fixedly mounted on both ends of the mounting rail 61. A slide 623 is arranged at the end of the limiting spring 621. A limiting frame 624 is arranged on the outer side of the slide 623. A limiting pin 625 is arranged at the inner front end of the limiting frame 624. The limiting pin 625 passes through the bottom rail 8 and is inserted into the inner side of the limiting hole 622 of the lower slide plate 9. The linkage component 63 includes a vertical rail 631, which is fixedly mounted on the top of the limiting frame 624.

The movable block 632 The front side is provided with a fixing block 633, and the inner side of the fixing block 633 is also provided with a limiting pin 625. The end of the limiting pin 625 passes through the top rail 4 and is inserted into the inner side of the limiting hole 622 at the rear end of the upper slide plate 5. The limiting assembly 62 pushes the slide 623 to drive the limiting frame 624 to move through the expansion and contraction of the limiting spring 621, so that the limiting pin 625 can be accurately inserted into the limiting holes 622 of the upper slide plate 5 and the lower slide plate 9, so as to achieve stable clamping and ensure the accurate position of the mold. The vertical rail 631 of the linkage assembly 63 cooperates with the movable block 632, so that the limiting pin 625 on the inner side of the fixing block 633 can also be accurately inserted into the corresponding limiting hole 622, so as to enhance the clamping effect and prompt the two limiting pins 625 to synchronously clamp and fix the upper slide plate 5 and the lower slide plate 9. The entire clamping mechanism 6 has a delicate structure and a stable clamping, which can effectively ensure the stability and accuracy of the upper and lower molds 10 during work, and improve the quality and efficiency of compression molding.

[0026] refer to Figure 5The clamping mechanism 6 includes a fixed frame 64 and a linkage frame 67. The linkage frame 67 is fixedly installed on the inner end of the back side of the slide 623. The fixed frame 64 is fixedly installed in the middle of the top rear side of the substrate 1. A guide plate 65 is slidably connected to the inner side of the fixed frame 64. The side shape of the guide plate 65 is set in a hook shape. A guide block 66 is set at the outer end of the guide plate 65. The guide plate 65 is fixedly installed on the inner end of the back side of the slider. The inner end of the guide plate 65 and the bottom inclined surface of the guide block 66 are fitted and connected. The inner end of the linkage frame 67 is set to an arc shape, and the overall front view shape of the guide block 66 is set to an isosceles triangle. The bottom inclined surface of the guide block 66 and the inner end arc surface of the guide plate 65 are fitted and connected. The four corners of the substrate 1 are provided with mounting holes 12, and the mounting holes 12 are set as countersunk holes. The linkage frame 67 is fixed to the inner end of the back side of the slide 623 and is connected to the fixed frame 64 cooperate with each other to ensure the stability of the structure and the continuity of the action. The fixing frame 64 is fixed in the middle of the top rear side of the base plate 1, with a reasonable position to provide a solid support for the internal components. The side of the guide plate 65 is hook-shaped, and it can slide flexibly and stably on the inside of the fixing frame 64. The guide block 66 at the outer end of the guide plate 65 is an isosceles triangle, and the bottom inclined surface fits tightly with the arc surface of the inner end of the guide plate 65. This design makes the force transmission more accurate and effective during operation, and can achieve precise guiding effect. The arc-shaped design of the inner end of the linkage frame 67 reduces friction and jamming, making the action smoother. The countersunk mounting holes 12 at the four corners of the base plate 1 facilitate the installation and fixation of the entire device, ensuring that there will be no loosening or displacement during work. On the whole, the card installation mechanism 6 is exquisitely designed, and the various components work together to improve the efficiency and stability of the card installation.

[0027] Principle and advantages of use: By setting the clamping mechanism 6, the device can be retracted and reset by the limit spring 621 during use, and then the slide 623 can be driven to slide on both sides of the mounting rail 61. The sliding of the slide 623 can drive the limit frame 624 to move. At this time, the limit frame 624 can drive the limit pin 625 at the bottom to be inserted into the inner side of the limit hole 622 of the lower slide plate 9, and the lower slide plate 9 is clamped and limited by the limit pin 625, so as to assist in clamping and fixing the lower mold 10. During this period, the inward movement of the limit frame 624 can drive the vertical rail 631 to move inward. At this time, the movable block 632 is slid upward to move, so that the limit pin 625 on the fixed block 633 can penetrate the top and be inserted into the inner side of the limit hole 622 at the upper end. At this time, the two groups of limit pins 625 can be driven to be synchronously inserted into the inner side of the limit hole 622 at the same time, so that the upper slide plate 5 and the lower slide plate 9 can be quickly clamped and fixed, so as to facilitate the installation and fixation of the upper mold 11 and the lower mold 10 at the same time.

[0028] By setting the linkage assembly 63, when the upper mold 11 and the lower mold 10 need to be separated during use of the device, the guide plate 65 can be pressed downward to move downward, and the downward movement of the guide plate 65 can drive the guide block 66 to move downward, so that the bottom inclined surface of the guide block 66 contacts the inner end of the linkage frame 67. At this time, the inclined surface of the guide block 66 can be used to squeeze the arc surface of the inner end of the linkage frame 67. The inclined surface and the arc surface can assist in guiding, so that the linkage frame 67 can be opened, and the linkage frame 67 can slide outward to drive the slide 623 to pull the limit spring 621 to be in an extended state. The outward movement of the slide 623 can synchronously drive the fixed frame 64 and the limit pin 625 inside it to separate from the lower slide plate 9. The limiting hole 622 of the upper slide 5 can be located at the bottom rail 8. At this time, the lower slide 9 inside the bottom rail 8 can be disassembled. When the lower slide 9 is removed, the lower mold 10 can be disassembled. As the limiting frame 624 moves outward, the vertical rail 631 can be driven to move outward. The vertical rail 631 moves outward and the fixed block 633 on the movable block 632 can be pulled to drive the limiting pin 625 at the upper end to disengage from the inner side of the limiting hole 622 of the upper slide 5. By separating the limiting pin 625 from the limiting hole 622 of the upper slide 5, the upper slide 5 can be quickly pulled out and disassembled, so that the device as a whole is convenient for quickly disassembling and replacing the upper mold 11 and the lower mold 10. The overall use does not require additional electronic components for card-connection installation, which can reduce the overall use cost of the device.
