Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing plug processing and manufacturing technology, specifically to an auxiliary tooling for through holes in sealing plugs. Background Technology
[0002] With the development of new energy electric vehicles and the widespread adoption of various all-in-one electric drive and control assemblies, the application of sealing plugs used in their internal rubber wiring harnesses is becoming increasingly widespread. The production control requirements for the sealing holes on these sealing plugs are also becoming more stringent. Therefore, a high-quality through-hole auxiliary tooling can more effectively control and determine the state of the sealing holes, thereby facilitating the smooth installation and use of the sealing plugs.
[0003] Currently, in the production process of sealing plugs, existing through-hole auxiliary tooling cores are divided into two types: flexible and rigid. Flexible cores, due to their tendency to bend, cannot completely remove the flash within the sealing hole, resulting in incomplete through-hole opening and hindering the smooth passage of wires during use. Furthermore, flexible cores may become clogged or even break within the sealing hole, further affecting the through-hole operation and the subsequent normal use of the sealing plug. While rigid cores can effectively remove flash, they are prone to damaging the inner wall of the sealing hole, causing scratches or deformation, leading to a decrease in sealing plug quality. Simultaneously, rigid cores allow any sealing hole on the sealing plug to be passed through, resulting in defective sealing plugs that are difficult to pass wires through being passed through the hole. These defective sealing plugs are difficult to pass wires through in later use, further reducing the production quality of the sealing plugs.
[0004] To address this, a through-hole auxiliary tooling for sealing plugs is proposed. Utility Model Content
[0005] The purpose of this invention is to provide an auxiliary tooling for through holes for sealing plugs, so as to solve the problem that the existing through hole auxiliary tooling mentioned in the background art has low efficiency and quality due to the easy bending of the soft mold core or the easy damage to the inner wall of the sealing hole by the rigid mold core.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary tooling for a through hole of a sealing plug, comprising an upper base, a placement groove formed downward at the center of the top surface of the upper base, a sliding groove formed upward at the center of the bottom surface of the upper base, a mold core slidably connected to the upper base within the placement groove, a lower base fixedly connected to the bottom surface of the upper base, a spring groove and a sliding through hole formed downward sequentially at the center of the top surface of the lower base, a sliding ring block slidably connected within the sliding groove, and a spring provided between the bottom surface of the sliding ring block and the inner bottom surface of the spring groove.
[0007] Preferably, a limiting ring block is fixedly connected to the bottom end of the mold core, and the limiting ring block is located in the sliding groove to prevent the mold core from leaving the placement groove.
[0008] Preferably, the limiting ring block abuts against the top surface of the sliding ring block.
[0009] Preferably, an inner sliding rod is fixedly connected to the center of the bottom surface of the sliding ring block, the inner sliding rod slides up and down within the sliding through hole, and the spring is sleeved on the outside of the inner sliding rod.
[0010] Preferably, the placement groove is used to place the sealing plug, the sealing plug includes a sealing hole inside it, and the position and number of the mold cores in the placement groove are matched with the sealing holes inside the sealing plug.
[0011] Preferably, the mold core is made of a soft material.
[0012] Preferably, the mold core is made of rubber or plastic.
[0013] Preferably, the lower base is detachably fixed to the upper base by fastening screws.
[0014] Preferably, the bottom surface of the lower base has a fixing opening, the fixing opening is stepped, and the tail of the fastening screw passes through the fixing opening and is threaded to the upper base.
[0015] Preferably, the two ends of the spring are always in contact with the bottom surface of the sliding ring block and the inner top surface of the spring groove, respectively, and neither end is fixedly connected to the sliding ring block or the spring groove.
[0016] Compared with the prior art, the beneficial effects of this utility model are: this tooling, through the setting and cooperation of the upper base, mold core and spring, utilizes the movable bottom end of the mold core and the known spring force, thereby not only completing the through hole operation of the sealing plug, but also distinguishing the unqualified sealing plugs, improving the through hole efficiency and the production quality of the sealing plugs.

[0019] 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.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0021] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.
[0022] Reference Figure 1-6 As shown, this utility model provides a technical solution for a through-hole auxiliary tooling for a sealing plug: An auxiliary tooling for sealing plugs includes an upper base 3. A placement groove 301 is formed downward at the center of the top surface of the upper base 3, and a sliding groove 302 is formed upward at the center of the bottom surface of the upper base 3. A mold core 5 is slidably connected to the upper base 3 within the placement groove 301. A lower base 4 is fixedly connected to the bottom surface of the upper base 3. A spring groove 401 and a sliding through hole 402 are formed downward sequentially at the center of the top surface of the lower base 4. A sliding ring block 502 is slidably connected within the sliding groove 302, and a spring 503 is provided between the bottom surface of the sliding ring block 502 and the inner bottom surface of the spring groove 401.
[0023] Working principle: Before introducing the usage process of this tooling, the structure of existing through-hole tooling will be briefly described, referring to... Figure 1-2 As shown, the existing through-hole fixture includes a base 1, a placement groove 101, and a mold core 102. The mold core 102 is fixedly installed in the base 1 within the placement groove 101. During use, because the bottom of the mold core 102 is fixed, when the operator holds the sealing plug 2 and aligns the mold core 102 with the sealing hole 201, the parting layer 202 inside the sealing hole 201 will prevent the mold core 102 from passing through. If the operator applies more force, the mold core 102 is easily bent, which not only fails to open the parting layer 202 but also causes the mold core 102 to become blocked inside the sealing hole 201, thus preventing further through-hole drilling of the sealing plug 2 and even affecting the subsequent normal use of the sealing plug 2.
[0024] When using this tooling, the operator holds the sealing plug 2, aligns the mold core 5 with the sealing hole 201, and then presses down the sealing plug 2. At this time, the mold core 5 will gradually pass through the sealing hole 201. When the mold core 5 reaches the parting layer 202 inside the sealing hole 201, the mold core 5 is blocked, which causes the sliding ring block 502 to move downward in the sliding groove 302. At this time, the spring 503 is compressed. As the operator increases the force, the spring 503 is continuously compressed, and the force on the parting layer 202 from the mold core 5 gradually increases. If the mold core 5 still does not pass through the sealing hole 201 after the sealing plug 2 is completely placed in the placement groove 301, the quality of the sealing plug 2 is unqualified. Conversely, the quality of the sealing plug 2 is qualified, and the parting layer 202 inside the sealing plug 2 will be completely removed.
[0025] This tooling, through the arrangement and cooperation of the upper base 3, the mold core 5, and the spring 503, utilizes the movable bottom end of the mold core 5 and the known spring force of the spring 503 to not only complete the through-hole operation of the sealing plug 2, but also identify the unqualified sealing plug 2, thereby improving the through-hole efficiency and the production quality of the sealing plug 2. The structure is simple, efficient, and easy to operate, making it suitable for widespread application.
[0026] Reference Figure 1-6 As shown, in an optional embodiment: a limiting ring block 501 is fixedly connected to the bottom end of the mold core 5. The limiting ring block 501 is located within the sliding groove 302 and is used to prevent the mold core 5 from disengaging from the placement groove 301. It should be noted that this setting avoids the mold core 5 from being lost during the carrying, transportation, or use of this tooling, ensuring the normal use of this tooling.
[0027] Reference Figure 1-6As shown, in an optional embodiment, the limiting ring block 501 abuts against the top surface of the sliding ring block 502. It should be noted that the limiting ring block 501 is not fixedly connected to the sliding ring block 502, which makes it easy to remove and replace the mold core 5 from this tooling, thus extending the service life of this tooling.
[0028] Reference Figure 1-6 As shown, in an optional embodiment: an inner slide rod 504 is fixedly connected to the center of the bottom surface of the sliding ring block 502. The inner slide rod 504 slides up and down within the sliding through hole 402, and the spring 503 is sleeved on the outside of the inner slide rod 504. It should be noted that, with this arrangement, the spring 503 is less prone to bending or even deformation during compression, ensuring the normal working condition of the spring 503 and extending the service life of this tooling.
[0029] Reference Figure 1-6 As shown, in an optional embodiment: the placement groove 301 is used to place the sealing plug 2, the sealing plug 2 including a sealing hole 201 inside it, and the position and number of the mold core 5 in the placement groove 301 are matched with the sealing holes 201 in the sealing plug 2. It should be noted that the above settings are specifically referred to Figure 6 As shown, there are two mold cores 5. This design makes the tooling highly targeted, allowing workers to easily match it with the corresponding sealing plugs 2, thus quickly completing the through-hole operation.
[0030] Reference Figure 1-6 As shown, in an optional embodiment, the mold core 5 is made of a soft material. It should be noted that this design avoids scratching or deforming the sealing hole 201 by the rigid material mold core 5, thereby improving the production quality of the sealing plug 2.
[0031] Reference Figure 1-6 As shown, in an optional embodiment, the mold core 5 is made of rubber or plastic. It should be noted that although the mold core 5 is made of a soft material, it still possesses good toughness, meaning that the mold core 5 can remain stable and will not bend or deform during the compression of the spring 503.
[0032] Reference Figure 1-6 As shown, in an optional embodiment: the lower base 4 is detachably fixed to the upper base 3 by fastening screws 6. (Refer to...) Figure 5 As shown, in an optional embodiment: the bottom surface of the lower base 4 has a fixing opening 403, which is stepped, and the tail of the fastening screw 6 passes through the fixing opening 403 and is threaded to the upper base 3. It should be noted that the head of the fastening screw 6 is located inside the fixing opening 403. This arrangement makes it easy to disassemble the upper base 3 and the lower base 4, thereby facilitating the replacement of the spring 503.
[0033] Reference Figure 1-6 As shown, in an optional embodiment, the two ends of the spring 503 always abut against the bottom surface of the sliding ring block 502 and the inner top surface of the spring groove 401, respectively, and neither end is fixedly connected to the sliding ring block 502 or the spring groove 401. It should be emphasized that this configuration allows the spring 503 to be easily disassembled, facilitating the replacement of springs 503 with different elastic coefficients according to actual needs, thereby significantly improving the applicability and flexibility of this tooling. It should be further explained that the reason for replacing the spring 503 with springs of different elastic coefficients is that when designing the sealing plug 2, the force required for wires of different hardness to pass through the sealing hole 201 on the sealing plug 2 varies. Therefore, it is necessary to replace the spring 503 with one of different elastic coefficients to meet the force required for the wires to pass through the sealing hole 201 on the sealing plug 2.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
