Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a mold base for merging optical fibers into a tape. Background Technology

[0002] In optical cable production, scattered optical fibers need to be combined into ribbons, which are then wound and wrapped into optical cables. Because the precision, smoothness, and durability requirements of the fiber combining molds are extremely high, optical cable manufacturers currently mostly use imported molds and mold bases to ensure the quality of communication transmission.

[0003] However, existing fiber optic merging and ribboning mold bases are expensive, have long purchase cycles, and lack timely after-sales service. Furthermore, the mold's assembly and disassembly structure is complex and labor-intensive, impacting the processing efficiency of fiber optic merging and ribboning. Additionally, after merging the fiber optics into ribbons, debris remains in the wire grooves within the mold. Cleaning the wire grooves requires disassembling the upper and lower molds and cleaning the grooves sequentially, a cumbersome and labor-intensive process. Therefore, a fiber optic merging and ribboning mold base is needed. Utility Model Content

[0004] The main purpose of this utility model is to provide a fiber optic merging and tape forming mold base. This utility model solves the problems of inconvenience in disassembling and assembling the existing fiber optic merging and tape forming mold base during use, as well as inconvenience in cleaning the wire grooves inside the upper and lower molds, by setting screws, limit blocks, support blocks A and B, grooves, drive components, drive plates A and B, brush blocks, positioning holes and positioning pins.

[0005] The technical solution adopted by this utility model to solve its technical problem is to combine optical fibers into a mold base, including an upper mold base and a lower mold base. An upper mold is snapped into the inner side of the upper mold base, and support blocks A are symmetrically welded to the outside of the upper mold. Quick connectors A, B, and C are threadedly connected to the outside of the upper mold base, with quick connector A located to the left of quick connector B and quick connector B to the left of quick connector C. A screw connected to the lower mold base is threaded onto the outside of the upper mold base. A lower mold is snapped into the inner side of the lower mold base, and limit blocks are symmetrically welded to the outside of the lower mold. The bottom is symmetrically welded with support block B. The upper and lower mold bases are symmetrically provided with grooves on the outside for support block A and support block B to enter. The inner sides of the upper and lower molds are provided with wire grooves for moving optical fibers. The top of the upper mold base is symmetrically inserted with positioning pins. The surfaces of the upper and lower molds are symmetrically provided with positioning holes for the positioning pins to enter. The lower mold base is symmetrically slidably connected with drive plate A and drive plate B. The ends of drive plate A and drive plate B are welded and fixed with brush blocks for cleaning the wire grooves. The lower mold base is provided with a drive assembly that drives drive plate A and drive plate B to move.

[0006] By adopting the above technical solution, when installing the mold base for fiber optic ribbon bundling, the lower mold is first placed on the lower mold base, and then the support block B at the bottom of the lower mold enters the groove on the lower mold base. Next, the upper mold is placed on the lower mold, and the limiting block outside the lower mold limits the upper mold. Then, the upper mold base is placed on the upper mold, and the positioning pin is inserted into the positioning holes on the upper and lower molds, allowing the upper and lower molds to pass through. The positioning pin precisely positions and fixes the connection. Then, the support block A outside the upper mold enters the groove inside the upper mold base, and the upper and lower mold bases are connected using screws, thus completing the installation of the mold base. When the mold base needs to be disassembled, the screw is turned and threaded into the lower mold base and removed. Then, the positioning pin is moved out of the positioning holes on the upper and lower molds, and the upper and lower molds are separated. Finally, the lower mold is removed from the lower mold base, thus completing the disassembly of the mold base. This facilitates the assembly and disassembly of the mold base for fiber optic ribbon bundling, improving the processing efficiency of fiber optic ribbon bundling.

[0007] The upper and lower molds can be made of high-hardness tungsten steel, which has a service life 3-5 times longer than conventional materials, a smaller coefficient of thermal expansion, higher corrosion resistance, more stable mold dimensions, and higher flatness.

[0008] After the optical fiber is combined into a strip in the upper and lower molds, the drive assembly in the lower mold base drives drive plate A and drive plate B to move laterally towards each other. Then, the brush blocks at the ends of drive plate A and drive plate B enter the grooves opened in the upper and lower molds, so that the brush blocks can move in the grooves, thereby facilitating the cleaning of the grooves opened in the upper and lower molds.

[0009] Specifically, the drive assembly includes a bidirectional lead screw, drive sleeve A, and drive sleeve B. The bidirectional lead screw is rotatably connected inside the lower mold base, and drive sleeve A and drive sleeve B are threadedly connected to the outside of the bidirectional lead screw.

[0010] By adopting the above technical solution, when it is necessary to move drive plate A and drive plate B, the bidirectional lead screw in the lower mold base rotates, and then drive sleeve A and drive sleeve B outside the bidirectional lead screw are limited by the external structure. Then drive sleeve A drives drive plate A to move, and drive sleeve B drives drive plate B to move. The end of the bidirectional lead screw is interference-fitted with a bearing.

[0011] Specifically, both the upper and lower molds have channels A and B on their surfaces, with channel A located to the left of channel B.

[0012] By adopting the above technical solution, channels A and B are opened on the surfaces of both the upper and lower molds, which facilitates the entry of quick connectors A, B, and C into the interior of the upper and lower molds.

[0013] Specifically, the top of the drive sleeve A is welded to the end of the drive plate A, and the top of the drive sleeve B is welded to the end of the drive plate B.

[0014] By adopting the above technical solution, drive sleeve A is connected to drive board A at one end, and drive sleeve B is connected to drive board B at the other end, which facilitates the movement of drive board A and drive board B.

[0015] Specifically, the lower mold base is externally connected to a handle that drives the bidirectional lead screw to rotate.

[0016] By adopting the above technical solution, when it is necessary to drive the bidirectional lead screw to rotate, the handle outside the lower mold base is rotated, so that the handle drives the bidirectional lead screw to rotate.

[0017] The beneficial effects of this utility model are:

[0018] (1) The optical fiber merging into a tape mold base of this utility model, when installing the optical fiber merging into a tape mold base, first place the lower mold on the lower mold base, then the support block B at the bottom of the lower mold enters the groove opened on the lower mold base, then place the upper mold on the lower mold, the limiting block outside the lower mold limits the upper mold, then place the upper mold base on the upper mold, then insert the positioning pin into the positioning hole opened on the upper mold and the lower mold, so that the upper mold and the lower mold pass through, and the positioning pin is precisely positioned and fixedly connected, then the upper mold outside the upper mold... Support block A enters the groove in the upper mold base, and then the upper mold base and lower mold base are connected by screws to complete the installation of the mold base. When the mold base needs to be disassembled, turn to the screw and screw it out from the lower mold base. Then, remove the positioning pin from the positioning hole in the upper and lower molds, and then separate the upper mold and lower mold. Then, remove the lower mold from the lower mold base to complete the disassembly of the mold base. This facilitates the disassembly and assembly of the mold base for fiber optic ribbon bonding and improves the processing efficiency of fiber optic ribbon bonding.

[0019] (2) The optical fiber merging into a strip mold base of the present invention, after the optical fiber is merged into a strip in the upper mold and the lower mold, the driving component in the lower mold base drives the driving plate A and the driving plate B to move laterally towards each other. Then the brush block at the end of the driving plate A and the driving plate B enters the groove opened in the upper mold and the lower mold, so that the brush block moves in the groove, thereby facilitating the cleaning of the groove opened in the upper mold and the lower mold.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] To improve the processing efficiency of fiber optic cable bundling, as one embodiment of this utility model, such as... Figure 1 , Figure 2 and Figure 3 As shown, the optical fiber merging mold base of this utility model includes an upper mold base 1 and a lower mold base 8. An upper mold 2 is snapped into the inner side of the upper mold base 1, and support blocks A10 are symmetrically welded to the outside of the upper mold 2. Quick connectors A15, B16, and C17 are threaded onto the outer side of the upper mold base 1, with quick connector A15 located to the left of quick connector B16 and quick connector B16 located to the left of quick connector C17. A screw 18 is threaded onto the outer side of the upper mold base 1 and connects to the lower mold base 8. A lower mold 3 is snapped into the inner side of the lower mold base 8, and limit blocks 4 are symmetrically welded to the outer side of the lower mold 3. Support blocks are symmetrically welded to the bottom of the lower mold 3. The upper mold base 1 and lower mold base 8 of block B12 are symmetrically provided with grooves 13 on their exteriors to allow support blocks A10 and B12 to enter. The upper mold 2 and lower mold 3 are both provided with wire grooves 11 on their interiors to allow the optical fiber to move. The top of the upper mold base 1 is symmetrically inserted with positioning pins 19. The surfaces of the upper mold 2 and lower mold 3 are symmetrically provided with positioning holes 21 to allow the positioning pins 19 to enter. The lower mold base 8 is symmetrically slidably connected with drive plates A6 and B7, and brush blocks 5 for cleaning inside the wire grooves 11 are welded and fixed at the ends of drive plates A6 and B7. The lower mold base 8 is provided with a drive assembly 25 that drives drive plates A6 and B7 to move.

[0027] When installing the mold base for merging optical fibers into a strip, first place the lower mold 3 onto the lower mold base 8. Then, the support block B12 at the bottom of the lower mold 3 enters the groove 13 on the lower mold base 8. Next, place the upper mold 2 onto the lower mold 3. The limiting block 4 outside the lower mold 3 limits the upper mold 2. Then, place the upper mold base 1 onto the upper mold 2. Then, insert the positioning pin 19 into the positioning hole 21 on the upper mold 2 and the lower mold 3, so that the upper mold 2 and the lower mold 3 pass through. The positioning pin 19 precisely positions and fixes the connection. Then, the support block A10 outside the upper mold 2 enters the upper mold base 8. The upper mold base 1 and the lower mold base 8 are connected by screws 18 within the groove 13 inside the mold base 1, thus completing the installation of the mold base. When the mold base needs to be disassembled, screws 18 and screws 18 are turned into the lower mold base 8 and removed. Then, the positioning pins 19 are moved out from the positioning holes 21 on the upper mold 2 and the lower mold 3. Then, the upper mold 2 and the lower mold 3 are separated. Then, the lower mold 3 is removed from the lower mold base 8, thus completing the disassembly of the mold base. This facilitates the disassembly and assembly of the mold base for fiber optic ribbon bonding and improves the processing efficiency of fiber optic ribbon bonding.

[0028] After the optical fibers are combined into a strip in the upper mold 2 and the lower mold 3, the drive assembly 25 in the lower mold base 8 drives the drive plate A6 and the drive plate B7 to move laterally towards each other. Then, the brush block 5 at the end of the drive plate A6 and the drive plate B7 enters the wire groove 11 opened in the upper mold 2 and the lower mold 3, so that the brush block 5 moves in the wire groove 11, thereby facilitating the cleaning of the wire groove 11 opened in the upper mold 2 and the lower mold 3.

[0029] To move driver board A6 and driver board B7, for example, as follows: Figure 3 As shown, the present invention also includes the following: the drive assembly 25 includes a bidirectional lead screw 23, a drive sleeve A14 and a drive sleeve B24; the bidirectional lead screw 23 is rotatably connected inside the lower mold base 8; and the drive sleeve A14 and the drive sleeve B24 are threadedly connected to the outside of the bidirectional lead screw 23.

[0030] When in use, when the drive plate A6 and drive plate B7 are to be moved, the bidirectional lead screw 23 inside the lower mold base 8 rotates. Then, the drive sleeve A14 and drive sleeve B24 outside the bidirectional lead screw 23 are limited by the external structure. Then, the drive sleeve A14 drives the drive plate A6 to move, and the drive sleeve B24 drives the drive plate B7 to move.

[0031] To allow quick couplings A15, B16, and C17 to enter the upper mold 2 and lower mold 3, for example, as follows: Figure 2 As shown, the present invention also includes channels A9 and B20 on the surfaces of the upper mold 2 and the lower mold 3, with channel A9 located to the left of channel B20.

[0032] During use, channels A9 and B20 are provided on the surfaces of the upper mold 2 and the lower mold 3, respectively, to facilitate the entry of quick connectors A15, B16 and C17 into the interior of the upper mold 2 and the lower mold 3.

[0033] To move driver board A6 and driver board B7, for example, as follows: Figure 3 As shown, the present invention also includes the top of the drive sleeve A14 being welded to the end of the drive plate A6, and the top of the drive sleeve B24 being welded to the end of the drive plate B7.

[0034] During use, drive sleeve A14 is connected to the end of drive board A6, and drive sleeve B24 is connected to the end of drive board B7, which facilitates the movement of drive board A6 and drive board B7.

[0035] To drive the bidirectional lead screw 23 to rotate, for example, as follows: Figure 3 As shown, the present invention also includes a handle 22 that drives the bidirectional lead screw 23 to rotate, which is inserted into the outside of the lower mold base 8.

[0036] When in use, to drive the bidirectional lead screw 23 to rotate, rotate the handle 22 outside the lower mold base 8, so that the handle 22 drives the bidirectional lead screw 23 to rotate.

[0037] In use, when installing the mold base for merging optical fibers into a strip, the lower mold 3 is first placed on the lower mold base 8. Then, the support block B12 at the bottom of the lower mold 3 enters the groove 13 on the lower mold base 8. Next, the upper mold 2 is placed on the lower mold 3, and the limiting block 4 outside the lower mold 3 limits the upper mold 2. Then, the upper mold base 1 is placed on the upper mold 2. Then, the positioning pin 19 is inserted into the positioning hole 21 on the upper mold 2 and the lower mold 3, so that the upper mold 2 and the lower mold 3 pass through. The positioning pin 19 is precisely positioned and fixedly connected. Then, the support block A10 outside the upper mold 2... Enter the groove 13 opened in the upper mold base 1, and then use screw 18 to connect the upper mold base 1 and the lower mold base 8 to complete the installation of the mold base. When the mold base needs to be disassembled, turn to screw 18 and screw 18 into the lower mold base 8 to take it out. Then, move the positioning pin 19 out of the positioning hole 21 opened on the upper mold 2 and the lower mold 3, and then separate the upper mold 2 and the lower mold 3. Then, take the lower mold 3 out of the lower mold base 8 to complete the disassembly of the mold base. This facilitates the disassembly and assembly of the mold base for fiber optic ribbon bonding and improves the processing efficiency of fiber optic ribbon bonding.

[0038] After the optical fibers are combined into a strip in the upper mold 2 and the lower mold 3, the drive assembly 25 in the lower mold base 8 drives the drive plate A6 and the drive plate B7 to move laterally towards each other. Then, the brush block 5 at the end of the drive plate A6 and the drive plate B7 enters the wire groove 11 opened in the upper mold 2 and the lower mold 3, so that the brush block 5 moves in the wire groove 11, thereby facilitating the cleaning of the wire groove 11 opened in the upper mold 2 and the lower mold 3.

[0039] When it is necessary to move the drive plate A6 and drive plate B7, the bidirectional lead screw 23 inside the lower mold base 8 rotates, and then the drive sleeve A14 and drive sleeve B24 outside the bidirectional lead screw 23 are limited by the external structure. Then the drive sleeve A14 drives the drive plate A6 to move, and the drive sleeve B24 drives the drive plate B7 to move.

[0040] Both the upper mold 2 and the lower mold 3 have channels A9 and B20 on their surfaces to facilitate the entry of quick connectors A15, B16 and C17 into the upper mold 2 and the lower mold 3.

[0041] Drive sleeve A14 is connected to the end of drive board A6, and drive sleeve B24 is connected to the end of drive board B7, which facilitates the movement of drive board A6 and drive board B7.

[0042] When you want to drive the bidirectional lead screw 23 to rotate, rotate the handle 22 outside the lower mold base 8 so that the handle 22 drives the bidirectional lead screw 23 to rotate.
