[0026] Due to the popularity of electronic products and unhealthy use in current society, the number of myopic people is increasing, and thus the use of glasses is becoming more and more widespread. Compared with conventional glasses, contact lenses are more portable and aesthetic.

[0027] The contact lenses in the related art cause the wearer's eyeball to be dry because they need to be attached to the eyeball for a long time and there is no liquid passage between the contact lens and the eyeball. There is no contact lens mold for the problem of the wearer's eyeball being dry in the related art of making contact lenses by a mold.

[0028] Based on this, in order to improve the problem of no contact lens mold for the problem of the wearer's eyeball being dry in the related art, the embodiments of the present application provide the following solutions.

[0029] Please refer to Figures 1 to 3 The embodiments of the present application provide a full-automatic forming mold 100 of a contact lens, which comprises a female die 10, a male die 20 and an adjusting part 30, wherein: The concave mold 10 has a first space 101.

[0030] The convex mold 20 cooperates with the concave mold 10 to form an injection cavity 102 between the concave mold 10 and the convex mold 20.

[0031] The adjusting part 30 is movably arranged on the convex mold 20, and the adjusting part 30 comprises a channel forming piece 31 movably arranged on the convex surface of the convex mold 20.

[0032] The adjusting part 30 is used to move the channel forming piece 31 to the convex surface of the convex mold 20 when the convex surface of the convex mold 20 and the concave surface of the concave mold 10 form the injection cavity 102, so that a fluid channel can be formed on the contact surface of the contact lens and the eyeball; the adjusting part 30 is also used to move the channel forming piece 31 into the convex mold 20 when the convex mold 20 and the concave mold 10 are separated, so that the channel forming piece 31 is separated from the fluid channel on the contact lens.

[0033] It can be understood that the concave mold 10 is a component for injecting a silicon hydrogel; for example, the concave mold 10 is a metal material mold or a polypropylene mold with a first space 101, and the shape of the first space 101 is a hemispherical space or a semi-ellipsoidal space. The convex mold 20 is a component for cooperating with the concave mold 10 to form an injection cavity 102; for example, the convex mold 20 can be a mold with a hemispherical body or a mold with a semi-ellipsoidal body, and the radius of the convex mold 20 is smaller than the radius of the first space 101. The channel forming piece 31 is a component for forming a liquid channel on the contact lens; for example, the channel forming piece 31 can be a long strip-shaped mold.

[0034] As can be seen from the above, the contact lens full-automatic forming mold 100 provided by the embodiments of the present application injects a silicon hydrogel into the first space 101, and then inserts one end of the convex mold 20 with a convex surface into the first space 101, so that the silicon hydrogel in the first space 101 forms the shape of a contact lens. Compared with the scheme of obtaining a contact lens by polishing, this scheme is simple to operate, thereby speeding up the production of contact lenses. By arranging the channel forming piece 31 on the convex mold 20, a concave liquid channel can be formed on the side of the contact lens in contact with the eyeball during the formation of the contact lens, so that the liquid can flow in the fluid channel, thereby preventing the eyeball from drying.

[0035] Exemplarily, the channel forming piece 31 may increase the probability of damage to the contact lens during demolding; by arranging the channel forming piece 31 as a movable channel forming piece 31, it can be demolded step by step after the contact lens is formed, and the demolding of the channel forming piece 31 and the contact lens, and the step-by-step demolding of the concave mold 10 and the convex mold 20 and the contact lens, can prevent interference between the demolding forces of the two components during the demolding process, thereby reducing the probability of damage to the contact lens during the demolding process.

[0036] In some embodiments, referring to Figures 1 to 3 , the male mold 20 comprises an injection molding part 21, an adjusting mounting part 22, a fixing part 23 and a stabilizing part 24, wherein: The injection molding part 21 has a second space 210, and an outer surface of the injection molding part 21 is formed with a convex surface; the channel forming member 31 is movably arranged on the injection molding part 21 and located in the second space 210.

[0037] The adjusting mounting part 22 is arranged at an end of the injection molding part 21 away from the female mold 10; the adjusting mounting part 22 has an adjusting space 220, and the adjusting space 220 is in communication with the second space 210.

[0038] The fixing part 23 is arranged at an end of the adjusting mounting part 22 away from the injection molding part 21; the fixing part 23 has a clamping space 230, and the clamping space 230 is in communication with the adjusting space 220; the fixing part 23 is used for cooperating with the clamping of the mechanical hand.

[0039] The stabilizing part 24 is arranged at an end of the fixing part 23 away from the fixing part 23.

[0040] It can be understood that the injection molding part 21 is a component for cooperating with the female mold 10 to form an injection molding cavity 102; for example, the injection molding part 21 can be a hemisphere or a semi-ellipsoid, etc. The adjusting mounting part 22 is a component for mounting the adjusting part 30; for example, the adjusting mounting part 22 can be a cylinder. The fixing part 23 is a component for cooperating with the clamping of the mechanical hand; for example, the fixing part 23 can be a circular column. The stabilizing part 24 is a component for stably placing the male mold 20 on the workbench; for example, the stabilizing part 24 can be a circular column.

[0041] In this way, the radius of the stabilizing portion 24 in the convex mold 20, the fixing portion 23, the adjusting mounting portion 22 and the injection molding portion 21 is set to be the largest, so that the convex mold 20 can be stably placed on the workbench, and the convex mold 20 can be kept stable during the clamping process of the mechanical hand, thereby facilitating the clamping of the convex mold 20. The fixing portion 23 is arranged to enable the mechanical hand to more stably clamp the convex mold 20, and the convex mold 20 can more stably enter each step of the contact lens manufacturing process, thereby improving the quality of the contact lens. The adjusting mounting portion 22 is arranged at one end of the injection molding portion 21, so that a part of the adjusting portion 30 is arranged on the adjusting mounting portion 22, and the other part is arranged on the injection molding portion 21. The second space 210 is arranged on the injection molding portion 21, the adjusting space 220 is arranged on the adjusting mounting portion 22, the clamping space 230 is arranged on the fixing portion 23, and the stabilizing portion 24 is arranged as a circular column. The second space 210, the adjusting space 220, the clamping space 230 and the passage of the stabilizing portion 24 are connected, so as to accelerate the heat dissipation speed of the convex mold 20, and thereby accelerate the solidification speed of the contact lens.

[0042] Optionally, in some embodiments, referring to Figures 1 to 3 , the adjusting portion 30 is provided with an adjusting hole 221, and the adjusting space 220 is connected with the adjusting hole 221. The injection molding portion 21 is provided with a mounting space 211, and the second space 210 is connected with the mounting space 211. The passage forming member 31 is movably arranged in the mounting space 211 and extends into the adjusting space 220. The adjusting portion 30 further comprises a connecting member 32 and a first trigger member 33, wherein: The connecting member 32 is arranged in the adjusting space 220, and one end of the connecting member 32 is hinged to the passage forming member 31.

[0043] The first trigger member 33 is movably arranged in the adjusting hole 221, and one end of the first trigger member 33 is hinged to the other end of the connecting member 32.

[0044] The first trigger member 33 is used to push the passage forming member 31 to move onto the convex surface of the convex mold 20 through the connecting member 32 when the convex surface of the convex mold 20 and the concave surface of the concave mold 10 form the injection cavity 102.

[0045] It can be understood that the connecting member 32 is a member for connecting the first trigger member 33 and the passage forming member 31. For example, the connecting member 32 can be a double-hinged rod or a double-hinged shell. The first trigger member 33 is a member for providing power to the passage forming member 31. For example, the first trigger member 33 can be a single-hinged rod or a single-hinged shell.

[0046] In this way, when the adjusting portion 22 enters the first space 101, the inner wall of the female mold 10 pushes the first trigger 33 to move towards the adjusting hole 221, and the channel forming piece 31 is moved to partially extend into the installation space 211 through the connecting piece 32, so that the channel forming piece 31 can help the contact lens to form a liquid channel. For example, a scheme composed of a distance sensor, a control element and a power device; the channel forming piece 31 is arranged on the power output end of the power device, the distance sensor is arranged on the side wall of the first space 101, and the control element is electrically connected to the distance sensor and the power device, respectively; the above scheme is complex due to the distance sensor, the control element and the power device, so that it needs a certain space to place, however, the contact lens mold cannot have enough space to install the distance sensor, the control element and the power device; and the distance sensor, the control element and the power device also increase the manufacturing cost. The scheme in the present application can simplify the contact lens mold and reduce the manufacturing cost.

[0047] Optionally, referring to Figures 1 to 3 , the adjusting portion 30 further comprises a first elastic element 34, the first elastic element 34 is arranged in the communication hole, one end of the first elastic element 34 is connected to the first trigger 33, and the other end is connected to the inner side wall of the communication hole; the first elastic element 34 is used to drive the channel forming piece 31 to move into the installation space 211 completely when the male mold 20 and the female mold 10 are separated.

[0048] It can be understood that the first elastic element 34 is a component for providing a restoring force to the first trigger 33; for example, the first elastic element 34 can be a spring or a rubber elastic element.

[0049] In this way, when the adjusting portion 22 is separated from the first space 101, the first elastic element 34 pushes the first trigger 33 to move away from the adjusting hole 221, and the channel forming piece 31 is moved to completely enter the installation space 211 through the connecting piece 32, so that the channel forming piece 31 is moved out of the liquid channel of the contact lens, thereby facilitating the subsequent separation of the male mold 20.

[0050] Exemplarily, referring to Figures 1 to 3 , the inner diameter of the first space 101 is smaller than the diameter of the first trigger 33, so that the first trigger 33 is retracted into the adjusting hole 221 when entering the first space 101.

[0051] In this way, by making the inner diameter of the first space 101 smaller than the diameter of the first trigger 33, the side wall of the first space 101 can push the first trigger 33 to retract into the adjusting hole 221. Compared with the scheme of directly arranging a power device, the above scheme can simplify the scheme and effectively reduce the manufacturing cost.

[0052] In some embodiments, referring to Figures 1 to 3 , the contact lens full-automatic forming mold 100 further comprises a sealing element 40, which is arranged on the outer sidewall of the adjusting mounting portion 22.

[0053] It can be understood that the sealing element 40 is a component for preventing the silicone hydrogel from flowing out of the injection cavity 102; for example, the sealing element 40 can be a rubber sealing ring or a plastic sealing ring, etc.

[0054] In this way, by arranging the sealing element 40 on the outer sidewall of the adjusting mounting portion 22, and locating the sealing element 40 between the first trigger 33 and the injection molding portion 21, the silicone hydrogel is fixed in the injection cavity 102.

[0055] Optionally, in some embodiments, referring to Figures 1 to 3 , the fixing portion 23 has a third space 231 and a clamping hole 232, the clamping hole 232 being in communication with the third space 231; the contact lens full-automatic forming mold 100 further comprises a dustproof portion 50, a part of the dustproof portion 50 being arranged in the third space 231, and another part of the dustproof portion 50 being arranged in the clamping hole 232.

[0056] It can be understood that the dustproof portion 50 is a component for preventing dust from polluting the injection molding portion 21 and the channel forming element 31; for example, the dustproof portion 50 can be a component composed of a power mechanism 51, a dustproof support 52 and a dustproof cover 53.

[0057] In this way, since there is some included angle between the channel forming element 31 and the injection molding portion 21, some dust will be hidden in the included angle and is not easy to be removed. By arranging the dustproof portion 50, the injection molding portion 21 and the channel forming element 31 are isolated from the external space, thereby preventing dust, so as to reduce the influence of dust on the quality of the contact lens.

[0058] Optionally, referring to Figures 1 to 3 , the dustproof portion 50 comprises the power mechanism 51, the dustproof support 52 and the dustproof cover 53, wherein: A part of the power mechanism 51 is arranged in the third space 231, and another part of the power mechanism 51 is arranged in the clamping hole 232.

[0059] The dustproof support 52 is arranged on the power output end of the power mechanism 51, and the dustproof support 52 is located in the adjusting mounting portion 22.

[0060] The dustproof cover 53 is arranged on the dustproof support 52, and the dustproof cover 53 is used for completely covering the male die 20, thereby preventing the male die 20 from being polluted.

[0061] The power mechanism 51 is used to drive the dustproof support 52 to rotate reversely in the case that the mechanical arm clamps the fixing part 23, and then the dustproof cover 53 is shrunk to leak the injection molding part 21; the power mechanism 51 is also used to drive the dustproof support 52 to rotate forwardly in the case that the mechanical arm releases the fixing part 23, and then the dustproof cover 53 is unfolded to cover the injection molding part 21.

[0062] It can be understood that the power mechanism 51 is a device for providing power for the dustproof support 52; for example, the power mechanism 51 can be a mechanism composed of the second trigger 511, the rack 512, the gear 513 and the second elastic element 514; for another example, the power mechanism 51 can also be a motor, and a power output end of the motor is connected with the dustproof support 52.

[0063] In this way, the dustproof support 52 is driven to rotate by the power mechanism 51, and then the dustproof cover 53 is driven to rotate, so as to cover or leak the injection molding part 21; the above scheme can effectively reduce the influence of dust on the quality of contact lenses.

[0064] In some embodiments, referring to Figures 1 to 3 The power mechanism 51 comprises the second trigger 511, the rack 512, the gear 513 and the second elastic element 514, wherein: The second trigger 511 is movably arranged in the clamping hole 232.

[0065] The rack 512 is arranged in the third space 231.

[0066] The gear 513 is rotatably arranged in the third space 231, and the gear 513 is engaged with the rack 512; the dustproof support 52 is connected with the gear 513.

[0067] The second elastic element 514 is arranged in the third space 231, and one end of the second elastic element 514 is connected with an end of the rack 512 away from the second trigger 511, and the other end of the second elastic element 514 is connected with a side wall of the third space 231 facing the injection molding part 21.

[0068] The second trigger 511 is used to be pushed by the mechanical arm to move the rack 512 towards the second elastic element 514, and then drive the gear 513 to rotate reversely, so as to close the dustproof cover 53; the second elastic element 514 is used to push the rack 512 to move away from the second elastic element 514 in the case that the mechanical arm is separated from the second trigger 511, and then drive the gear 513 to rotate forwardly, so as to open the dustproof cover 53.

[0069] It can be understood that the second trigger 511 is a member for pushing the rack 512 to move forward; for example, the second trigger 511 can be a block or a shell, etc. The second elastic element 514 is a member for pushing the rack 512 to move reversely; for example, the second elastic element 514 can be a spring or a rubber elastic element, etc.

[0070] In this way, the robot clamps the second trigger 511 and pushes the second trigger 511 to move into the clamping hole 232, thereby pushing the rack 512 to move towards the second elastic element 514, thereby driving the gear 513 to rotate reversely, so as to close the dust cover 53; the robot releases the second trigger 511, and under the action of the restoring force of the second elastic element 514, the rack 512 moves away from the second elastic element 514, thereby driving the gear 513 to rotate forward, so as to open the dust cover 53. The above scheme can associate the opening or closing of the dustproof part 50 with the clamping of the robot, and can drive the opening or closing of the dustproof part 50 by the robot, thereby simplifying the structure and reducing the production cost.

[0071] The embodiment of the present application also provides a manufacturing method of a full-automatic contact lens forming mold, comprising: The male mold 20 and the female mold 10 are placed in corresponding positions of an injection molding device.

[0072] The male mold 20 is clamped to enable the male mold 20 to move and the dustproof part 50 of the male mold 20 to open.

[0073] The male mold 20 is moved to partially enter the first space 101, so that the injection molding cavity 102 can be formed between the male mold 20 and the female mold 10.

[0074] When the male mold 20 enters the first space 101, the channel forming member 31 moves to the convex surface of the male mold 20.

[0075] As known from the above, the male mold 20 and the female mold 10 are placed in corresponding positions of an injection molding device, so as to facilitate subsequent operations; the male mold 20 is clamped by a robot, and the robot also opens the dustproof part 50 of the male mold 20 in the clamping process; and the robot moves the male mold 20 to the injection molding part 21 and the adjusting and mounting part 22 to enter the first space 101, thereby enabling the male mold 20 and the female mold 10 to form the injection molding cavity 102. The inner side wall of the female mold 10 pushes the first trigger 33 to move the channel forming member 31 to the convex surface of the male mold 20, thereby enabling the contact lens to form a liquid channel, so as to prevent the eyeball from being dry.

[0076] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
