Description

Technical Field

[0001] This utility model relates to the field of contact lens mold-separation equipment, and in particular to a contact lens mold-separation equipment. Background Technology

[0002] It is known that the production technology of hydrophilic contact lenses can be completed by lathe cutting, rotational casting, injection molding or a combination thereof. Among them, it is particularly common to use a two-part mold, in which a reactive mixture is injected between a lower mold for forming the front curved surface of the contact lens and an upper mold for forming the back curved surface of the contact lens to complete the molding process of the contact lens.

[0003] Existing contact lens mold-making equipment can often only process contact lenses of one diameter, which limits the equipment's capabilities. When processing contact lenses of different diameters, changing the mold to process contact lenses of different diameters is both restrictive and cumbersome. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a contact lens mold separating device.

[0005] This utility model is achieved by the following technical solution: a contact lens mold separating device, including a limiting seat, a lower mold assembly is provided on the surface of the limiting seat, and a driving assembly is provided inside the lower mold assembly.

[0006] The lower mold assembly includes an inner limiting shaft, which is fixedly connected to the surface of a limiting seat. A moving rod is slidably connected to the surface of the inner limiting shaft, and an outer limiting shaft is slidably connected to the surface of the moving rod. A limiting block is contacted on the surface of the moving rod. The outer wall of the limiting block is slidably connected to the surface of the inner limiting shaft. A rotating rod is rotatably connected to the inner wall of the limiting block. A support plate is rotatably connected to the outer wall of the rotating rod. The lower mold is fixedly connected to the top of the support plate. A second limiting block is rotatably connected to the inner wall of the support plate at the end away from the limiting block. Several limiting blocks and second limiting blocks are provided. A limiting plate is fixedly connected to the surface of several limiting blocks and second limiting blocks. The outer wall of the limiting plate is slidably connected to the surface of the outer limiting shaft. A connecting screw is rotatably connected to the inner wall of the limiting block. The end of the connecting screw away from the limiting block is threadedly connected to the inner wall of the second limiting block.

[0007] As a further improvement to the above solution, there are two inner limiting shafts, which are symmetrically arranged around the moving rod. There are several moving rods. There are also two outer limiting shafts, which are symmetrically arranged around the moving rod.

[0008] As a further improvement to the above solution, two rotating rods are provided, and the two rotating rods are symmetrically arranged with the moving rod as the center.

[0009] Through the above technical solution, the connecting screw can be rotated outward to disengage from the inside of the second limiting block, and then the connecting screw can be pulled outward to disengage from the inside of the limiting block. Then, the limiting block can be rotated around the rotating rod as the center, thereby disengaging the limiting block from the inner limiting shaft, the outer limiting shaft, and the surface of the limiting seat.

[0010] As a further improvement to the above solution, the drive assembly includes a motor mounting base, a drive motor is fixedly connected to the surface of the motor mounting base, and a motor rotating rod is fixedly connected to the output end of the drive motor.

[0011] As a further improvement to the above solution, the outer wall of the motor rotating rod is rotatably connected to the inner wall of the limiting seat, the motor rotating rod passes through the inner wall of the limiting seat and extends therethrough, and a drive gear is fixedly connected to the outer wall of the motor rotating rod.

[0012] As a further improvement to the above scheme, the outer wall of the drive gear is meshed with the outer wall of the moving rod, and the end of the moving rod away from the drive gear is meshed with a second drive gear, and the inner wall of the second drive gear is fixedly connected with a second rotating rod.

[0013] As a further improvement to the above solution, the outer wall of the rotating rod is rotatably connected to the inner wall of the limiting seat, and a support seat is fixedly connected to the surface of the limiting seat. There are two support seats, which are symmetrically arranged with the moving rod as the center.

[0014] Through the above technical solution, the drive motor is operated, the output end of the drive motor rotates the motor rotating rod, the motor rotating rod rotates the drive gear, and the drive gear meshes with the second drive gear to slide along the inner limit shaft and the outer limit shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes an outward-rotating connecting screw to disengage it from the inner limit block two. The connecting screw is then pulled outwards, freeing it from the limit block. The limit block is then rotated around a rotating rod, disengaging it from the inner limit shaft, outer limit shaft, and limit seat surface. A support plate is then pushed towards the limit block two, disengaging the limit block and limit block two from the inner and outer limit shafts. This allows the support plate to disengage the lower mold, and finally, the limit block and limit block two disengage from the moving rod. This allows for the replacement of lower molds with different diameters, increasing the flexibility and applicability of the equipment.

[0017] This invention utilizes a drive motor to rotate a motor rod at its output end. The motor rod rotates a drive gear, which meshes with a second drive gear and slides along the inner and outer limit shafts. This causes a uniformly arranged moving rod to move a limit block and a second limit block, which in turn move a support plate. The support plate then moves the lower mold, thereby transporting the contact lenses on the surface of the lower mold and facilitating the transport and processing of the contact lenses.

[0028] Please combine Figure 1-7This embodiment provides a contact lens mold separating device, including a limiting seat 1, a lower mold assembly 2 disposed on the surface of the limiting seat 1, and a driving assembly 3 disposed inside the lower mold assembly 2.

[0029] The lower mold assembly 2 includes an inner limiting shaft 201, which is fixedly connected to the surface of the limiting seat 1. A moving rod 202 is slidably connected to the surface of the inner limiting shaft 201, and an outer limiting shaft 203 is slidably connected to the surface of the moving rod 202. A limiting block 204 is disposed in contact with the surface of the moving rod 202. The outer wall of the limiting block 204 is slidably connected to the surface of the inner limiting shaft 201. A rotating rod 205 is rotatably connected to the inner wall of the limiting block 204, and a support plate 206 is rotatably connected to the outer wall of the rotating rod 205. The top of the support plate 206 is fixed. A lower mold 207 is connected. A second limit block 209 is rotatably connected to the inner wall of the support plate 206 away from the limit block 204. Several limit blocks 204 and second limit blocks 209 are provided. A limit plate 210 is fixedly connected to the surface of several limit blocks 204 and second limit blocks 209. The outer wall of the limit plate 210 is slidably connected to the surface of the outer limit shaft 203. A connecting screw 208 is rotatably connected to the inner wall of the limit block 204. The end of the connecting screw 208 away from the limit block 204 is threadedly connected to the inner wall of the second limit block 209.

[0030] There are two inner limit shafts 201, which are symmetrically arranged with the moving rod 202 as the center. There are several moving rods 202. There are two outer limit shafts 203, which are symmetrically arranged with the moving rod 202 as the center.

[0031] There are two rotating rods 205, which are symmetrically arranged with the moving rod 202 as the center, and several support plates 206 are provided.

[0032] The drive assembly 3 includes a motor mounting base 301, a drive motor 302 is fixedly connected to the surface of the motor mounting base 301, and a motor rotating rod 303 is fixedly connected to the output end of the drive motor 302.

[0033] The outer wall of the motor rotating rod 303 is rotatably connected to the inner wall of the limiting seat 1. The motor rotating rod 303 passes through the inner wall of the limiting seat 1 and extends therethrough. The outer wall of the motor rotating rod 303 is fixedly connected to the drive gear 304.

[0034] The outer wall of the drive gear 304 is meshed with the outer wall of the moving rod 202. The end of the moving rod 202 away from the drive gear 304 is meshed with the drive gear 305. The inner wall of the drive gear 305 is fixedly connected with the rotating rod 306.

[0035] The outer wall of the rotating rod 306 is rotatably connected to the inner wall of the limiting seat 1. The surface of the limiting seat 1 is fixedly connected to the support seat 307. There are two support seats 307, which are symmetrically arranged with the moving rod 202 as the center.

[0036] The implementation principle of a contact lens mold-separating device in this embodiment is as follows: By operating the drive motor 302, the output end of the drive motor 302 rotates the motor rotating rod 303, which in turn rotates the drive gear 304. The drive gear 304 meshes with the second drive gear 305, which slides along the inner limiting shaft 201 and the outer limiting shaft 203. Simultaneously, the moving rod 202 drives the second drive gear 305 to rotate around the second rotating rod 306. This causes the evenly arranged moving rod 202 to drive the limiting blocks 204 and 209, which in turn drive the support plate 206. The support plate 206 then moves the lower mold 207, thereby transporting the contact lenses on the surface of the lower mold 207, facilitating the transport of the contact lenses. The processing can be achieved by rotating the connecting screw 208 outward to disengage it from the inside of the second limiting block 209. Then, the connecting screw 208 is pulled outward to disengage it from the inside of the limiting block 204. Next, the limiting block 204 is rotated around the rotating rod 205, thereby disengaging the limiting block 204 from the inner limiting shaft 201, the outer limiting shaft 203, and the surface of the limiting seat 1. Then, the support plate 206 is pushed towards the second limiting block 209, thereby disengaging the limiting blocks 204 and the second limiting block 209 from the inner limiting shaft 201 and the outer limiting shaft 203. This allows the support plate 206 to drive the lower mold 207 to disengage, and then the limiting blocks 204 and the second limiting block 209 to disengage from the moving rod 202. This allows for the replacement of lower molds 207 with different diameters, increasing the flexibility and applicability of the equipment.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
