A mold fixing component

Abstract

This utility model belongs to the field of mold processing technology, specifically a mold fixing component, including a worktable. The top of the worktable has a hole, and a limiting ring is fixedly installed on the bottom of the inner wall of the hole. A rotating disk is rotatably installed on the top of the limiting ring. A cleaning component is provided on the top of the worktable. When a stepper motor is powered on, it drives two lead screws to rotate simultaneously. A moving rod moves back and forth along the outer surface of the lead screws, causing the moving rod to drive a cleaning brush installed at the bottom to move back and forth as well. The bottom end of the cleaning brush is attached to the top of the worktable. The back-and-forth movement of the cleaning brush sweeps the debris generated during the cutting of the lens mold body on the top of the worktable into the collection groove on the top of the worktable, achieving the effect of cleaning and collecting debris from the top of the worktable. This prevents debris from accumulating on the top of the worktable and affecting the horizontal placement and clamping of the lens mold body to be processed on the worktable.

Description

Technical Field

[0001] This utility model belongs to the field of mold processing technology, specifically a mold fixing component. Background Technology

[0002] In the production of lenses, lens molds are required. By extruding molten resin material into the lens injection mold, a lens blank is quickly formed. The lens mold is formed by a cutting device. The lens mold to be processed is placed on the top of the worktable, and a fixing component is used to precisely position the lens mold under the cutting mold for processing.

[0003] To accelerate the efficiency of lens mold injection molding into lens blanks, multiple lens cavities are typically machined on the lens mold using a cutting device, allowing the mold to mold multiple lens blanks at once. However, machining multiple cavities on a single lens mold generates a large amount of debris. After one lens mold is completed, workers need to remove it before placing a new mold to be processed. The large amount of debris generated on the worktable accumulates on top, making the new lens mold unstable and unable to be precisely positioned. The debris must be cleaned before the new mold can be placed, a tedious process that impacts processing efficiency. Therefore, a mold fixing component is proposed to address these issues. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a mold fixing component.

[0005] The technical solution adopted by this utility model to solve its technical problem is a mold fixing component, including a worktable, a support leg fixedly installed at the bottom of the worktable, a hole opened at the top of the worktable, a limit ring fixedly installed at the bottom of the inner wall of the hole, a rotating disk rotatably installed at the top of the limit ring, a rotating component installed at the bottom of the rotating disk, a clamping component installed at the top of the rotating disk, and a cleaning component provided at the top of the worktable.

[0006] The cleaning assembly includes a collection trough located on the top of the workbench and a connecting plate 1 fixedly installed on the top of the workbench. A lead screw is rotatably mounted on the front of the connecting plate 1, and a stepper motor is mounted through the back of the lead screw. A moving rod is threaded onto the outer surface of the lead screw, and a cleaning brush is mounted on the bottom of the moving rod. A connecting plate 2 is rotatably connected to the front of the lead screw. A support block is fixedly installed on the inner wall of the collection trough, and a screen is installed on the top of the support block. A lifting column is fixedly installed on the top of the screen.

[0007] Preferably, the cleaning brush is positioned above the collection trough, the bottom of the inner wall of the collection trough has a water outlet, and the connecting plate is fixedly installed on the top of the workbench.

[0008] Furthermore, the screen can block debris, and the cutting fluid can flow out from the outlet through the screen.

[0009] Preferably, there are two lead screws and two stepper motors, which are symmetrically distributed inside the connecting plate and used to move the moving rod of the belt back and forth.

[0010] Preferably, the rotating assembly includes a mounting plate fixedly installed on the bottom of the worktable, a drive motor is mounted on the bottom of the mounting plate, and the output shaft of the drive motor passes through the mounting plate and is mounted on the bottom of the rotating disk.

[0011] Preferably, the clamping assembly includes a fixed plate fixedly installed on the top of the rotating disk, a threaded hole is provided on the right side of the fixed plate, a threaded rod is threadedly connected inside the threaded hole, a clamping plate is rotatably installed on the left side of the threaded rod, and a rotating handle is fixedly installed on the right side of the threaded rod.

[0012] Preferably, there are two clamping components, which are symmetrically distributed on the top of the rotating disk, and the lens mold body is disposed between the two clamping components.

[0013] Furthermore, before the lens mold is clamped and fixed on both sides, it can be placed into the slot on the top of the rotating disk for initial positioning to avoid the problem of inaccurate clamping of the lens mold by the two clamping components.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model, by energizing and starting a stepper motor, drives two lead screws to rotate simultaneously. A moving rod moves back and forth along the outer surface of the lead screw, which in turn drives a cleaning brush installed at the bottom to move back and forth as well. The bottom end of the cleaning brush is attached to the top of the worktable. The back and forth movement of the cleaning brush can sweep the debris generated by cutting the lens mold body on the top of the worktable into the collection groove opened on the top of the worktable. The debris falls into the top of the screen for collection. Pulling the lifting column can remove the screen and take out the collected debris for processing. This achieves the effect of cleaning and collecting debris on the top of the worktable, preventing debris from accumulating on the top of the worktable and affecting the horizontal placement and clamping of the lens mold body to be processed on the worktable.

[0016] 2. In this utility model, by rotating the handle, the clamping plate can be moved towards the center of the rotating disk, and the side of the lens mold body placed on the top of the rotating disk is squeezed and clamped to fix it. The two clamping plates are symmetrically distributed on the left and right sides of the lens mold body, and can squeeze and clamp both sides of the lens mold body together, so as to achieve the effect of clamping and fixing the lens mold body to the top of the rotating disk. When the drive motor is powered on, it can drive the rotating disk to rotate. The rotation angle of the lens mold body after the top of the rotating disk is limited and fixed by the clamping component is so that the cutting device can process the lens cavity in different positions of the lens mold body.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 As shown, a mold fixing assembly includes a worktable 1, with a support leg 11 fixedly installed at the bottom of the worktable 1, allowing the support leg 11 to place the worktable 1 horizontally. The top of the worktable 1 has an opening, and a limit ring 2 is fixedly installed at the bottom of the inner wall of the opening. A rotating disk 21 is rotatably installed on the top of the limit ring 2, which can support the rotating disk 21 and prevent it from falling off. A rotating component 22 is installed at the bottom of the rotating disk 21, and a clamping component 3 is installed on the top of the rotating disk 21. A cleaning component 4 is provided on the top of the worktable 1.

[0027] The cleaning component 4 includes a collection trough 401 located on the top of the workbench 1 and a connecting plate 402 fixedly mounted on the top of the workbench 1. A lead screw 403 is rotatably mounted on the front of the connecting plate 402, and a stepper motor 404 is mounted through the back of the lead screw 403. A moving rod 405 is threadedly connected to the outer surface of the lead screw 403, and a cleaning brush 406 is mounted at the bottom of the moving rod 405. A connecting plate 407 is rotatably connected to the front of the lead screw 403. A support block 408 is fixedly mounted on the inner wall of the collection trough 401, and a screen 409 is mounted on the top of the support block 408. A lifting column 410 is fixedly mounted on the top of the screen 409. The cleaning brush 406 is positioned above the collection trough 401, and a water outlet 5 is provided at the bottom of the inner wall of the collection trough 401. The connecting plate 407 is fixedly mounted on the top of the workbench 1. Two lead screws 403 and two stepper motors 404 are provided. The two lead screws 403 and the two stepper motors 404 are symmetrically distributed inside the connecting plate 402 and are used to move the moving rod 405 back and forth.

[0028] Through the above technical solution, connecting plate 1 402 and connecting plate 2 407 are fixedly installed at the top rear end and front end of the workbench 1, respectively. A lead screw 403 is rotatably installed between connecting plate 1 402 and connecting plate 2 407. A stepper motor 404 is installed on the back of the lead screw 403 through connecting plate 1 402. A moving rod 405 is threaded onto the outer surface of the lead screw 403. Two lead screws 403 and two stepper motors 404 are each installed inside the moving rod 405. The two stepper motors 404 are started by the controller, which can drive the two lead screws 403 to rotate simultaneously. The moving rod 405 moves back and forth along the outer surface of the lead screw 403, so that the moving rod 405 can drive the cleaning brush 406 installed at the bottom to move back and forth together. The bottom end of the cleaning brush 406 is attached to the top of the worktable 1. The back and forth movement of the cleaning brush 406 can sweep the debris generated by cutting the lens mold body 6 on the top of the worktable 1 into the collection groove 401 opened on the top of the worktable 1. The sides of the connecting plate 1 402 and the connecting plate 2 407 are both provided with collection grooves 401, so as to achieve the effect of cleaning and collecting debris on the top of the worktable 1 and avoid the debris from affecting the placement and clamping of the lens mold body 6 on the worktable 1.

[0029] It should be noted that a screen 409 is also installed inside the collection tank 401. The screen 409 is supported by a support block 408 fixed to the inner wall of the collection tank 401. The debris entering the collection tank 401 is blocked at the top of the screen 409. A water outlet 5 is provided at the bottom of the inner wall of the collection tank 401. The cutting fluid sprayed from the top of the workbench 1 can flow into the collection tank 401, fall after passing through the screen 409, and flow out from the water outlet 5. When too much debris accumulates on the top of the screen 409, the lifting column 410 can be pulled to remove and process the debris accumulated on the top of the screen 409.

[0030] Considering the issue of how to fix the lens mold body 6 to the top of the worktable 1 for processing, the following is presented: Figure 1 and 5 The specific structure of the clamping assembly 3 is disclosed. The clamping assembly 3 includes a fixed plate 301 fixedly installed on the top of the rotating disk 21. A threaded hole is opened on the right side of the fixed plate 301. A threaded rod 302 is threadedly connected inside the threaded hole. A clamping plate 303 is rotatably installed on the left side of the threaded rod 302. A rotating handle 304 is fixedly installed on the right side of the threaded rod 302.

[0031] There are two clamping components 3, which are symmetrically distributed on the top of the rotating disk 21. The lens mold body 6 is located in the middle of the two clamping components 3.

[0032] Through the above technical solution, a fixing plate 301 is fixedly installed on the top right side of the rotating disk 21. A threaded rod 302 is threadedly connected to a threaded hole inside the fixing plate 301. A clamping plate 303 is rotatably connected to the left side of the threaded rod 302. A rotating handle 304 is installed on the right side of the threaded rod 302. When the operator rotates the rotating handle 304, the clamping plate 303 can be moved towards the center of the rotating disk 21 to squeeze and clamp the side of the lens mold body 6 placed on the top of the rotating disk 21. There are two clamping plates 303, which are symmetrically distributed on the left and right sides of the lens mold body 6. They can squeeze and clamp the two sides of the lens mold body 6 together, achieving the effect of clamping and fixing the lens mold body 6 to the top of the rotating disk 21, which facilitates the cutting device to cut and process the top of the lens mold body 6.

[0033] It should be noted that the top of the rotating disk 21 is provided with a locking slot, which can initially limit the placement of the lens mold body 6 on the top of the rotating disk 21, avoiding the problem of the clamping plate 303 clamping the mirror mold inaccurately. In addition, the bristles of the cleaning brush 406 are higher than the fixed plate 301, so they will not be blocked by the fixed plate 301 and cannot move for cleaning.

[0034] Furthermore, considering that multiple lens cavities need to be cut into the top of the lens mold body 6, and the need to change the orientation of the lens mold body 6, the following is provided: Figure 2 , Figure 4 and Figure 5 The specific structure of the rotating assembly 22 is disclosed. The rotating assembly 22 includes a mounting plate 201 fixedly installed on the bottom of the worktable 1. A drive motor 202 is installed on the bottom of the mounting plate 201. The output shaft of the drive motor 202 passes through the mounting plate 201 and is installed on the bottom of the rotating disk 21.

[0035] Through the above technical solution, the bottom of the rotating disk 21 is equipped with a mating interface, and the top of the worktable 1 is fixedly equipped with a mounting plate 201, so that the drive motor 202 can be installed at the bottom of the mounting plate 201. Then, the output shaft of the drive motor 202 can pass through the mounting plate 201 and extend into the interior of the mating interface. The controller can start the drive motor 202 by powering it on, which can drive the rotating disk 21 to rotate. The top of the rotating disk 21 is fixed by the clamping component 3, and the lens mold body 6 is rotated by an angle, so that the cutting device can process the lens cavity in different positions of the lens mold body 6.

[0036] It should be noted that the controller has a switch assembly installed inside, which is used to electrically connect the stepper motor 404 and the drive motor 202, and can control the start and stop of the stepper motor 404 and the drive motor 202.

[0037] In summary, the working principle of this utility model is as follows:

[0038] When the lens mold body 6 is processed and fixed, the operator can rotate the handle 304 to move the clamping plate 303 toward the center of the rotating disk 21, and squeeze and clamp the side of the lens mold body 6 placed on the top of the rotating disk 21. The two clamping plates 303 are symmetrically distributed on the left and right sides of the lens mold body 6, and can squeeze and clamp the two sides of the lens mold body 6 together, so as to achieve the effect of clamping and fixing the lens mold body 6 to the top of the rotating disk 21, which facilitates the cutting device to cut the top of the lens mold body 6. When processing the lens cavity in different positions on the top of the lens mold body 6, the drive motor 202 is powered on and can drive the rotating disk 21 to rotate. The rotation angle of the lens mold body 6 after the top of the rotating disk 21 is limited and fixed by the clamping component 3 is adjusted so that the cutting device can process the lens cavity in different positions of the lens mold body 6.

[0039] When the lens mold body 6 is finished and replaced with another lens mold body 6, the debris generated by cutting on the worktable 1 hinders the horizontal placement of the lens mold body 6. The stepper motor 404 is powered on and started, which drives the two lead screws 403 to rotate simultaneously. The moving rod 405 moves back and forth along the outer surface of the lead screw 403, so that the moving rod 405 can drive the cleaning brush 406 installed at the bottom to move back and forth as well. The bottom end of the cleaning brush 406 is attached to the top of the worktable 1. The back and forth movement of the cleaning brush 406 can sweep the debris generated by cutting the lens mold body 6 on the top of the worktable 1 into the collection groove 401 opened on the top of the worktable 1. The debris falls into the top of the screen 409 for collection. Pulling the lifting column 410 can remove the screen 409 and take out the collected debris for processing, achieving the effect of cleaning and collecting debris on the top of the worktable 1, and preventing debris from accumulating on the top of the worktable 1 and affecting the horizontal placement and clamping of the lens mold body 6 on the worktable 1.
