Description

Technical Field

[0001] This utility model relates to the field of molding die technology, and in particular to a cable core compression molding die. Background Technology

[0002] In the production of cable cores, compaction molding is a crucial process to ensure the stability of the core structure and its electrical performance. Different mold tubes need to be replaced according to the different specifications of the cores. Existing mold tube replacement structures mostly use bolt fixing or a single snap-fit ​​method, which results in cumbersome and time-consuming replacement operations. Frequent mold changes can easily lead to increased production line downtime, affecting production efficiency.

[0003] Meanwhile, traditional fixed structures are prone to loosening during long-term, high-frequency vibration compaction operations, leading to decreased positioning accuracy of the mold tube and deviations in the core forming dimensions, thus affecting product quality stability. Furthermore, some structures lack secondary reinforcement designs, which may result in mold tube displacement under high-pressure compaction conditions, posing a safety hazard. Therefore, a new cable core compaction mold is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cable core compression molding die, which aims to improve the problems of cumbersome mold changing, loose fixing and poor precision in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable core compression molding die includes a die platform, a working tube fixedly connected to the outside of the die platform, a support sleeve fixedly connected to the outside of the working tube, a spring sleeved on the outside of the working tube, a sliding sleeve fixedly connected to one end of the spring, a plurality of locking balls engaged inside the working tube, a die tube slidably connected to the outside of the working tube, a groove formed on the outside of the die tube, and a fixing component for secondary fixing slidably connected to the outside of the support sleeve.

[0007] As a further description of the above technical solution:

[0008] The fixing component includes a locking tube, the locking tube being slidably connected to the outside of the support sleeve, and multiple slots being provided inside both the support sleeve and the sliding sleeve, with multiple locking blocks fixedly connected to the outside of the locking tube.

[0009] As a further description of the above technical solution:

[0010] The sliding sleeve is pushed to compress the spring, thereby releasing the compression of the multiple retaining balls, allowing the multiple retaining balls to move freely in the working tube, which facilitates the calibration of the tube groove;

[0011] As a further description of the above technical solution:

[0012] When the sliding sleeve is released, the spring releases its elastic force, which in turn pushes the sliding sleeve to squeeze the multiple retaining balls, so that the multiple retaining balls engage with the tube groove to complete the fixation;

[0013] As a further description of the above technical solution:

[0014] The locking blocks are externally slidably connected to the outside of the support sleeve and the sliding sleeve;

[0015] As a further description of the above technical solution:

[0016] Multiple locking blocks are externally engaged with the inside of the tube groove to complete secondary fixation.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, when replacing the mold tube, push the sliding sleeve to compress the spring, release the compression of the locking ball, pull out the original mold tube, insert the new one and adjust the tube groove to correspond with the locking ball, release the sliding sleeve, and the spring pushes it to compress the locking ball and lock it into the tube groove for fixed operation.

[0019] 2. In this utility model, the fixing component is centered on the locking tube and locking block, which cooperate with the tube grooves of the support sleeve and sliding sleeve. Initially, it is not locked, and the sliding sleeve fixes the mold tube by the force of the spring. Pushing the locking tube causes the locking block to embed into the tube groove, restricting displacement and enhancing rigidity; pulling in the opposite direction unlocks it, facilitating replacement and adjustment.

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1 to 4 This utility model provides an embodiment of a cable core compression molding die, including a die platform 1, which serves as the basic support component of the entire die. A working tube 2 is fixedly connected to the outside of the die platform 1, serving as the core load-bearing and guiding component. A support sleeve 3 is fixedly connected to the outside of the working tube 2, serving as auxiliary support and limiting function. A spring 4 is sleeved on the outside of the working tube 2, which generates elastic force through its own elastic deformation to provide continuous pressure and ensure the initial fixing effect. A sliding sleeve 5 is fixedly connected to one end of the spring 4, serving as a force transmission component. Multiple locking balls 6 are engaged inside the working tube 2, serving as direct fixing components. A die tube 7 is slidably connected to the outside of the working tube 2, serving as a component that directly participates in the cable core compression molding.

[0028] The mold tube 7 has a groove 8 on its outside. This groove 8 is designed as a mating structure, providing engagement space for the ball clamping 6 and the locking block 10 of the fixing component. Through mechanical engagement with the ball clamping 6 and the locking block 10, the mold tube 7 and related components are fixed. Pushing the sliding sleeve 5 compresses the spring 4, thereby releasing the compression of the multiple ball clamping 6, allowing them to move freely within the working tube 2, facilitating the calibration of the groove 8. When the sliding sleeve 5 is released, the spring 4 releases its elastic force, pushing the sliding sleeve 5 to compress the multiple ball clamping 6, causing them to engage with the groove 8 and complete the fixation. A fixing component for secondary fixing is slidably connected to the outside of the support sleeve 3.

[0029] Reference Figure 3 , Figure 4 The fixing component includes a locking tube 9, which is designed as the main frame of the fixing component. The locking tube 9 is slidably connected to the outside of the support sleeve 3. Both the support sleeve 3 and the sliding sleeve 5 have multiple tube grooves 8 inside. The tube grooves 8 are designed as the core contact components for achieving secondary fixing.

[0030] Multiple locking blocks 10 are fixedly connected to the outside of the locking tube 9. The locking blocks 10 are designed to provide locking space. Through precise cooperation with the locking blocks 10, mechanical limiting is formed, so that the support sleeve 3, the sliding sleeve 5 and the locking tube 9 form a stable overall structure, further consolidating the fixing effect of the mold tube 7. The multiple locking blocks 10 are externally slidably connected to the outside of the support sleeve 3 and the sliding sleeve 5, and the multiple locking blocks 10 are externally engaged with the inside of the tube groove 8 to complete secondary fixing.

[0031] Working principle: When changing different mold tubes 7, first push the sliding sleeve 5 to compress the spring 4. This action releases the compression of multiple retaining balls 6, allowing them to move freely inside the working tube 2. At this time, the original mold tube 7 can be pulled out of the working tube 2, and the new mold tube 7 can be inserted into the working tube 2. Next, adjust the position of the new mold tube 7 so that the tube groove 8 precisely aligns with the position of the retaining balls 6. Then, release the sliding sleeve 5, and the spring 4 will release its elasticity, pushing the sliding sleeve 5 to compress the multiple retaining balls 6 again, causing the retaining balls 6 to engage with the tube groove 8 of the new mold tube 7, completing the fixing operation of the new mold tube 7. After fixing, the cable core compression molding die can use the new mold tube 7 to perform corresponding compression molding operations on the cable core. Through this process, different mold tubes 7 can be replaced to adapt to production needs.

[0032] The fixing assembly, centered on the locking tube 9 and locking block 10, works in conjunction with the groove 8 of the support sleeve 3 and sliding sleeve 5 to achieve "double-limiting fixation." Initially, the locking tube 9 is fitted over the support sleeve 3, and the locking block 10 is not embedded in the groove 8. The sliding sleeve 5, with the spring force of the spring 4, presses against the retaining ball 6, completing the initial fixation of the mold tube 7. When locking is triggered, pushing the locking tube 9 along the axial direction of the support sleeve 3 causes the locking block 10 to slide, aligning it and embedding it into the groove 8, thus limiting the relative displacement between the support sleeve 3 and the sliding sleeve 5. After locking takes effect, the sliding sleeve 5 cannot move due to the locking block 10's engagement, ensuring continuous pressure from the spring 4 on the retaining ball 6. The locking tube 9 also fills the gap at the joint and enhances rigidity. Pulling the locking tube 9 in the opposite direction disengages the locking block 10 from the groove 8, allowing the sliding sleeve 5 to regain its mobility, facilitating the replacement or adjustment of the mold tube 7. This adapts to the tight-pressing operation environment and ensures stable mold operation.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
