Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cable production, in particular to a cable core pressing and paralleling die. Background Art
[0002] The appearance of the cable is the most intuitive impression that the cable product gives to customers. Cables with better roundness can improve user satisfaction with the product. During the production process of fire-resistant cables, it was analyzed that the main reason for the cable's uneven appearance is that the cable core is not tight and round enough before squeezing the fire-resistant mud. In addition, the vibration of the equipment will cause the amplitude to be too large, resulting in the falling off of the fire-resistant mud.
[0003] Currently, the extruder dies widely used in the cable production industry for compression and splicing are mostly openable and retractable. However, these dies exhibit poor stability during compression and splicing operations. Specifically, the dies are susceptible to interference from external forces during cable production, preventing them from fully closing and, consequently, failing to achieve the desired compression effect. This defect not only causes the wire cores to become loose but also directly leads to the detachment of the fireproofing putty on the compressed wire cores, compromising the overall quality and performance of the cable. Utility Model Content
[0004] The purpose of the utility model is to provide a cable core compression and paralleling mold to solve the technical problem in the prior art that the mold is easily disturbed by external forces during the cable production process, resulting in the inability to completely close and thus unable to achieve the expected compression effect.
[0005] The technical problem to be solved by the present invention can be achieved through the following technical solutions: A cable core pressing and paralleling mold includes a first module and a second module, the side of the first module is provided with a first pressing groove and a guide slide groove, the side of the second module is provided with a second pressing groove and a guide slider is fixedly arranged, and the guide slider is slidably connected to the guide slide groove, the side of the guide slide groove is provided with a limiting card groove, and the side of the guide slider is fixedly provided with a limiting card block that slidably cooperates with the limiting card groove.
[0006] As a further solution of the present invention: guide slots are provided on both sides of the first pressing slot, and guide sliders that slide in cooperation with the corresponding guide slots are fixedly provided on both sides of the second module.
[0007] As a further solution of the present invention: a limit stop is fixedly provided at one end of the guide slide groove.
[0008] As a further solution of the present invention: a positioning hole is provided on the side of the first module, a matching hole is provided on the side of the second module, and a locking rod is provided through the positioning hole and the matching hole.
[0009] As a further solution of the present invention: an external thread is fixedly provided on the outer side of the locking rod, and an internal thread matching with the locking rod is provided in both the positioning hole and the matching hole.
[0010] As a further solution of the present invention: both ends of the first pressing groove and the second pressing groove are provided with arc chamfers.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. Through the sliding cooperation between the guide slider and the guide slot and the locking structure between the limit block and the limit slot, the mold can maintain a high degree of stability after closing, effectively preventing the problem of the mold not being able to be completely closed due to external force interference.
[0013] 2. When the first and second modules move toward each other to close the mold, the guide slides on both sides slide simultaneously along their corresponding guide grooves.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] like Figures 1 to 6 As shown, a cable core pressing and paralleling mold includes a first module 1 and a second module 2. The side of the first module 1 is provided with a first pressing groove 3 and a guide slide groove 4, the side of the second module 2 is provided with a second pressing groove 5 and a guide slider 6 is fixedly set, and the guide slider 6 is slidably connected with the guide slide groove 4, the side of the guide slide groove 4 is provided with a limiting card groove 7, and the side of the guide slider 6 is fixedly provided with a limiting card block 8 that slidably cooperates with the limiting card groove 7.
[0026] Specifically, the mold consists of a first module 1 and a second module 2, which are structurally complementary. The first module 1 has a first pressing groove 3 and a guide slot 4 on its side, while the second module 2 has a second pressing groove 5 and a guide slide 6 on its side. The guide slide 6 and the guide slot 4 are connected by a sliding fit, ensuring smooth and precise docking of the first and second modules 1 and 2 when closed.
[0027] When the first and second molds 1 and 2 move toward each other to close the mold, the guide slider 6 slides along the guide slot 4 until it is fully inserted. Simultaneously, the stopper 8 fixed to the side of the guide slider 6 also slides along the stopper slot 7 provided on the side of the guide slot 4 and eventually inserts into it. This locking mechanism effectively prevents the mold from reopening due to external interference after closing, ensuring mold stability during the pressing operation.
[0028] When the mold is fully closed, the first and second grooves 3 and 5 together form a pressing hole for pressing the fireproofing putty onto the wire cores. The pressing action of the mold firmly presses the wire cores together, while also evenly compacting the fireproofing putty onto the wire cores, thereby improving the overall quality and performance of the cable.
[0029] Through the sliding cooperation between the guide slider 6 and the guide slot 4 and the locking structure between the limit block 8 and the limit slot 7, the mold can maintain a high degree of stability after closing, effectively preventing the problem of the mold being unable to be completely closed due to external force interference.
[0030] refer to Figure 2 and Figure 3 As shown, in some specific embodiments, to enhance the stability and ease of operation of the cable core compression and paralleling mold, guide slots 4 are provided on both sides of the first compression groove 3, and guide sliders 6 are fixedly provided on both sides of the second module 2, which slide in conjunction with the corresponding guide slots 4. When the first and second modules 1 and 2 move toward each other to close the mold, the guide sliders 6 on both sides slide simultaneously along the corresponding guide slots 4. This bilateral sliding fit ensures that the mold maintains a smooth and symmetrical motion trajectory during the closing process, thereby avoiding mold deflection or jamming caused by uneven force on one side.
[0031] refer to Figure 5 As shown, in some specific embodiments, to enhance the accuracy of the cable core compression and paralleling mold, a limit stopper 9 is fixedly provided at one end of the guide chute 4. During the mold closing process, the guide slider 6 slides smoothly along the guide chute 4. When the guide sliders 6 touch each other, it indicates that the first compression groove 3 and the second compression groove 5 are aligned, thereby simplifying the operation process of closing the first module 1 and the second module 2 and improving work efficiency. Precise mold alignment helps ensure that the cable cores receive uniform pressure and shape during the compression and paralleling process. This helps to improve the overall quality and consistency of the product.
[0032] refer to Figure 4 、 Figure 5 and Figure 6 As shown, in some specific embodiments, in order to enhance the stability of the cable core compression and paralleling mold, a positioning hole 10 is opened on the side of the first module 1, and a matching hole 11 is opened on the side of the second module 2. A locking rod 12 is provided through the positioning hole 10 and the matching hole 11. When the first module 1 and the second module 2 are closed and the positioning hole 10 and the matching hole 11 are completely aligned, the operator inserts the locking rod 12 from one side so that it passes through the positioning hole 10 and the matching hole 11, thereby ensuring the alignment accuracy and locking effect of the mold. Precise mold alignment and a stable locking state help ensure that the cable core obtains uniform pressure and shape during the compression and paralleling process. This helps to improve the overall quality and consistency of the product.
[0033] In some specific embodiments, in order to further enhance the stability and reliability of the cable core compression and paralleling mold, the outer side of the locking rod 12 is fixed with an external thread, and the positioning hole 10 and the matching hole 11 are both provided with an internal thread that matches the locking rod 12.
[0034] When the positioning hole 10 and the matching hole 11 are completely aligned, the operator inserts the externally threaded locking rod 12 from one side and rotates it clockwise. As the locking rod 12 rotates, its external threads gradually engage with the internal threads in the positioning hole 10 and the matching hole 11 until the locking rod 12 is fully inserted and firmly fixed on the other side.
[0035] After the locking rod 12 is fully inserted and tightened, it tightly connects the first module 1 and the second module 2 together to form a stable whole. At this time, the mold is in a completely closed and locked state, and the cable core compression and paralleling operation can begin.
[0036] After the processing is completed, the operator only needs to rotate the locking rod 12 counterclockwise to gradually separate the external thread from the internal thread in the positioning hole 10 and the matching hole 11, and then pull the locking rod 12 out of the hole to easily open the mold and take out the processed cable core.
[0037] The mold can be locked more securely when closed by the tight fit of the external threads of the locking rod 12 with the internal threads in the positioning hole 10 and the matching hole 11. This threaded connection not only provides additional locking force, but also helps prevent the mold from accidentally opening due to external interference during processing.
[0038] refer to Figure 1 、 Figure 2 and Figure 3 As shown, in some specific embodiments, in order to optimize the fluidity of the cable core in the compacting and paralleling mold and reduce the friction and damage of the core at the edge of the pressing groove, both ends of the first pressing groove 3 and the second pressing groove 5 are provided with arc chamfers 13.
[0039] When the cable cores are fed into the die, they first contact the arc chamfers 13 at both ends of the groove. These chamfers guide the cores into the groove and reduce the direct friction between the cores and the edge of the groove.
[0040] Once the wire cores enter the groove, they will flow along the bottom and two side walls of the groove. In this process, the structure of the arc chamfer 13 ensures that the wire cores flow more smoothly in the groove, reducing the resistance or damage caused by sudden changes in shape.
[0041] When the cable cores are pressed and connected, they will leave the other end of the groove. Similarly, the arc chamfer 13 plays a role in smooth transition, helping the cores to leave the groove easily and avoiding scratches or breaks caused by sharp edges.
[0042] By providing curved chamfers 13 at both ends of the first and second grooves 3, 5, direct friction between the cable core and the edges of the first and second grooves 3, 5 is reduced. This not only helps extend the life of the mold but also reduces the risk of damage to the core during processing, making the compression and paralleling of the cable core smoother and more efficient. This reduces downtime and rework caused by poor core flow or damage, thereby improving overall processing efficiency.
[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
