Description

Technical Field

[0001] This utility model belongs to the field of lens processing technology, specifically relating to a lens mold ejection structure. Background Technology

[0002] In the manufacturing process of optical lenses, lens polishing and grinding molds play a crucial role. Traditional lens polishing and grinding molds often rely on a tight fit between the mold groove and the outer wall of the lens to achieve high-precision polishing. However, this fitting method brings many problems in actual operation. To achieve ideal polishing accuracy, significant pressure needs to be applied between the mold groove and the outer wall of the lens to ensure the lens remains stably in the desired position during polishing, thus obtaining a precise polishing effect. However, when the lens is ejected from the mold groove after polishing, the lens is subjected to considerable pressure due to the continuous pressure on its outer wall during polishing. This pressure easily creates indentations on the lens surface, which can negatively impact the lens's optical performance and appearance quality, such as causing abnormal light refraction and damaged surface flatness, severely affecting the final quality of the ejected lens. Utility Model Content

[0003] This utility model provides a lens mold ejection structure, which solves the problem that ejection during lens polishing and grinding can easily affect lens quality.

[0004] This utility model provides the following technical solution: It includes a grinding mold body, a support plate below the grinding mold body, a connecting hole at the center of the grinding mold body, a support ring slidably connected to the inner wall of the connecting hole, an inner support ring plate fixedly connected to the inner wall of the support ring, a vertical rod slidably connected to the inner wall of the inner support ring plate, a limit post fixedly connected to the top of the vertical rod, a support plate fixedly connected to the bottom of the vertical rod, the support plate being detachably connected to the top of the support plate, a lens groove on the grinding mold body, a threaded ring slidably connected to the inner wall of the lens groove, a connecting rod connecting the support ring and the threaded ring, a sealing plate threadedly connected to the inner wall of the threaded ring, and several equally spaced support posts on the threaded ring, the support posts corresponding to the outer wall of the threaded ring.

[0005] The grinding mold body has a through groove on its top that communicates with the lens groove, and the threaded ring and the support ring are connected by a connecting rod, which is located in the through groove.

[0006] The support plate has a fixed sliding rod at its top, and the grinding mold body has a sliding hole that matches the sliding rod.

[0007] The support plate is fixedly connected to an installation plate on its outer side. The installation plate has a bottom groove. A limit rod is fixedly connected to the inner wall of the bottom groove. An "L"-shaped rod is slidably connected to the limit rod. The top end of the "L"-shaped rod corresponds to the bottom end of the grinding mold body.

[0008] The grinding mold body has a clearance groove on its top for making way for the support column, and a connecting groove on its top that communicates with the clearance groove. The support columns are connected by an arc-shaped rod, and the connecting groove matches the arc-shaped rod.

[0009] The bottom end of the sealing plate is fixedly connected to an adjusting rod, and a hole is provided at the connection between the grinding mold body and the sealing plate to allow the adjusting rod to move.

[0010] The beneficial effects of this utility model are: by supporting the height of the threaded ring and the sealing plate through the support ring, the height of the upright, the limiting column and the support plate can be adjusted. In conjunction with the height adjustment of the grinding mold body, the lens can be placed inside the support column and taken out through the sealing plate, thereby reducing the risk of damage to the lens surface when the device pushes the lens out and applies pressure to the lens surface.

[0018] Please see Figures 1-5 The present invention provides the following technical solution: a grinding mold body 1 is included, a support plate 12 is provided below the grinding mold body 1, a connecting hole 2 is provided at the center of the grinding mold body 1, a support ring 24 is slidably connected to the inner wall of the connecting hole 2, an inner support ring plate 241 is fixedly connected to the inner wall of the support ring 24, a vertical rod 3 is slidably connected to the inner wall of the inner support ring plate 241, a limit post 31 is fixedly connected to the top of the vertical rod 3, a support plate 32 is fixedly connected to the bottom of the vertical rod 3, the support plate 32 is detachably connected to the top of the support plate 12, a lens groove 11 is provided on the grinding mold body 1, a threaded ring 27 is slidably connected to the inner wall of the lens groove 11, the support ring 24 and the threaded ring 27 are connected by a connecting rod 271, a sealing plate 28 is threadedly connected to the inner wall of the threaded ring 27, and a number of equally spaced support posts 25 are provided on the threaded ring 27, the support posts 25 corresponding to the outer wall of the threaded ring 27.

[0019] In this implementation scheme: When processing optical lenses, before polishing, the dimensions of the grinding mold body 1 are the same as the lens dimensions, so that it functions as a lens polishing and grinding mold. During use, the support plate 12 below the grinding mold body 1 supports and elevates it, ensuring that the grinding mold body 1 is positioned such that the connecting hole 2 at the center of the grinding mold body 1 encloses the support ring 24, allowing the surface of the grinding mold body 1 to be relatively flat. At this time, the outer wall of the support ring 24 connects with the outer wall of the threaded ring 27 that engages with the inner wall of the lens groove 11 at the top of the grinding mold body 1. The threaded ring 27 can then be used to polish the lens. The polished lens is supported and positioned within the lens groove 11, allowing it to be stably placed within the inner wall of the groove for polishing. The inner wall of the threaded ring 27, connected by the sealing plate 28, forms a support surface that conforms to the lens surface, providing support and protection. This prevents indentations caused by insufficient pressure on the bottom of the lens, which could affect production quality. Several support pillars 25 positioned above the threaded ring 27 are supported within the clearance groove 23 at the top of the polishing mold body 1. These pillars are positioned within the clearance groove 23, with their tops resting on its inner wall. When the lens is pushed out of the lens groove 11, the grinding mold body 1 can move down from the height of the support plate 12. At this time, the support plate 32 installed at the top of the support plate 12 can support the upright 3 and the limiting post 31. The upright 3 is slidably connected to the support ring 24, causing the grinding mold body 1, the support ring 24, and the threaded ring 27 to move downward. At this time, the limiting post 31 is above the device. Rotating the limiting post 31 separates the support plate 32 from the top of the support plate 12. Then, by pulling the limiting post 31 upward, the limiting post 31, the upright 3, and the support plate 32 can support and lift the support ring 24, thereby causing the support ring 24 to drive the threaded ring 27 and the sealing plate 28 upward. The displacement allows the threaded ring 27 and the sealing plate 28 to maintain constant support for the bottom surface of the lens, thus pushing the lens out of the lens groove 11. At this time, the support columns 25 are evenly distributed on the outer side of the lens. The support columns 25 can support the outer wall of the lens, thereby supporting and fixing the position of the lens and preventing the lens from detaching. At this time, the lens is connected to the support columns 25, so that it receives less external support force and its position is limited. When the sealing plate 28 is rotated to push the lens on the threaded ring 27 out from between the support columns 25, the frictional pressure is less, thereby reducing the risk of damage to the lens surface when the device pushes the lens out and applies pressure to the lens surface.

[0020] The top of the grinding mold body 1 has a through groove 21 that communicates with the lens groove 11. The threaded ring 27 and the support ring 24 are connected by a connecting rod 271, which is located in the through groove 21. The through groove 21 on the top of the grinding mold body 1 is used to allow room for the connecting rod 271 connecting the support ring 24 and the threaded ring 27, so that when the support ring 24 is pulled upward, the threaded ring 27 can be separated synchronously with it. The connecting rod 271 is located in the through groove 21, which avoids the connecting rod 271 being limited when connecting the through groove 21 and the threaded ring 27, thus ensuring that the lens can be taken out from the grinding mold body 1.

[0021] A sliding rod 13 is fixed at the top of the support plate 12, and a sliding hole 131 matching the sliding rod 13 is provided on the grinding mold body 1. The sliding rod 13 fixedly connected to the top of the support plate 12 can connect with the sliding hole 131 provided on the grinding mold body 1, so that when the height of the grinding mold body 1 is adjusted on the support plate 12, the position of the grinding mold body 1 is limited, so that the grinding mold body 1 can ensure vertical displacement.

[0022] A mounting plate 14 is fixedly connected to the outside of the support plate 12. A bottom groove 141 is provided on the mounting plate 14. A limiting rod 142 is fixedly connected to the inner wall of the bottom groove 141. An "L"-shaped rod 15 is slidably connected to the limiting rod 142. The top end of the "L"-shaped rod 15 corresponds to the bottom end of the grinding mold body 1. The mounting plate 14 is fixedly connected to the outside of the support plate 12 for installing the bottom of the "L"-shaped rod 15 through the bottom groove 141. The limiting rod 142 passes through the bottom of the "L"-shaped rod 15. At this time, the "L"-shaped rod 15 can slide steadily on the mounting plate 14. When the lens is in the lens groove 11 opened on the grinding mold body 1, the "L"-shaped rod 15 can support and fix the grinding mold body 1 at this height. The height of the support ring 24 and the grinding mold body 1 can be supported at the same level as the top end of the limiting post 31, so as to avoid affecting the grinding operation of the lens in the lens groove 11.

[0023] The top of the grinding mold body 1 is provided with a clearance groove 23 for making way for the support column 25. The top of the grinding mold body 1 is provided with a connecting groove 22 that communicates with the clearance groove 23. The support columns 25 are connected by an arc rod 26. The connecting groove 22 matches the arc rod 26. The clearance groove 23 on the top of the grinding mold body 1 is used to make way for the position of the support column 25, and the connecting groove 22 is used to make way for the arc rod 26. At this time, the arc rod 26 and the support column 25 can be connected to ensure that the support column 25 supports and limits the outer wall of the lens, thereby providing a protective effect for the lens.

[0024] An adjusting rod 281 is fixedly connected to the bottom end of the sealing plate 28. A hole is provided at the connection between the grinding mold body 1 and the sealing plate 28 to allow the adjusting rod 281 to move. The adjusting rod 281 fixedly connected to the bottom end of the sealing plate 28 can facilitate the rotation of the sealing plate 28. At this time, the sealing plate 28 can be rotated, so that the sealing plate 28 pushes the lens held in the support column 25, so that the lens can be taken out from the support column 25.

[0025] The working principle and usage process of this utility model are as follows: During use, the grinding mold body 1 is erected at the same height as the limiting post 31, ensuring that the support post 25 and the arc-shaped rod 26 are flush with the grinding mold body 1, thus guaranteeing the grinding of the lens. When the lens needs to be pushed out of the lens groove 11, the grinding mold body 1 can be lowered from its position on the support plate 12, placing the limiting post 31 above the device. By lifting the limiting post 31 upwards, the support ring 24 is supported and lifted, causing the support ring 24 to move the threaded ring 27 and the sealing plate 28 upwards, thereby causing the threaded ring 27 and the sealing plate 28 to move upwards. While maintaining the support for the bottom surface of the lens, the lens is pushed out of the lens groove 11. At this time, the support columns 25 are evenly distributed on the outer side of the lens. The support columns 25 can support the outer wall of the lens, thereby supporting and fixing the position of the lens to prevent it from detaching. At this time, the lens is connected to the support columns 25, so that it receives less external support force and its position is limited. When the lens on the threaded ring 27 is pushed out from between the support columns 25 by rotating the sealing plate 28, the friction pressure is less, thereby reducing the risk of damage to the lens surface when the device pushes the lens out and applies pressure to the lens surface.
