Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold for a ferrule for a needle insertion point. Background Technology

[0002] The use of indwelling needles can reduce the pain and fear of injections caused by repeated intravenous punctures in children, alleviate parental anxiety, facilitate clinical medication administration, and reduce the workload of nurses and children. Therefore, indwelling needles are widely used in clinical practice. The most crucial part of the indwelling needle melting machine is the melting mold that processes the indwelling needle tip. Generally, operators use automated equipment to insert the indwelling needle tip into the melting mold for processing.

[0003] The "fusion head" refers to the device used in the manufacturing process of indwelling needles to connect the needle tip and the catheter via heat fusion. It is usually made of metal and has a specific internal cavity structure to accommodate the needle tip and for heating. The fusion head plays a key role in the manufacturing process of indwelling needles, and its structure usually includes one or more limiting grooves or clamping structures for fixing the needle tip and performing thermoforming or welding operations.

[0004] A document with publication number CN217729711U discloses a mold for an indwelling needle fuse head, including a mold plate mounted on a workbench. A fuse head is detachably mounted within the mold plate. The fuse head is a cylindrical structure with one open end, and a retaining ring is fixedly sleeved on its outer wall. The mold plate is a rectangular plate structure, consisting of an upper plate and a bottom plate from top to bottom. The upper and bottom plates are inserted and fixed together, and the fuse head is held in place by the insertion and engagement of the upper and bottom plates. This utility model design uses a mold plate composed of two detachable upper and bottom plates, with the fuse head positioned and inserted between them for stable installation and easy replacement and maintenance. A guideable insert-holding base is incorporated at the bottom of the bottom plate, allowing for quick and stable assembly onto the workbench. This overall structure facilitates flexible disassembly of each module, improving maintenance convenience.

[0005] However, this type of mold can only process one type of indwelling needle fuse. If it is necessary to process other specifications of indwelling needle fuses, the mold needs to be changed, which reduces the practicality of the mold.

[0006] Therefore, it is necessary to provide a mold for the indwelling needle melting point to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments. Example

[0028] like Figure 1-5The diagram shows the indwelling needle melting head mold provided by this utility model, comprising: a support platform 1, on which a mold is mounted, the mold including a lower mold 2 and an upper mold 3, the bottom of the lower mold 2 being connected to the support platform 1, the upper mold 3 being connected to the lower mold 2 by bolts, a melting head body 4 being installed between the upper mold 3 and the lower mold 2, and two clamping components 5 symmetrically mounted on both the upper mold 3 and the lower mold 2, the clamping groove 6 formed between the two clamping components 5 being used to limit the side protrusions of the melting head body 4, the melting head body 4 adopting the structure disclosed in CN217729711U, which will not be described in detail here, the clamping components 5 including a first limiting ring 7, a second limiting ring 8 and a third limiting ring 9 nested in order of decreasing size, and if necessary, a fourth limiting ring, a fifth..., etc. can be added sequentially. The positioning ring 9 is nested within the second limiting ring 8, which in turn is nested within the first limiting ring 7. The first limiting ring 7 is fixedly connected to the upper mold 3 / lower mold 2. It's worth noting that the inner diameters of the first limiting ring 7, second limiting ring 8, and third limiting ring 9 are adapted to the corresponding specifications of the ferrule body 4. Taking the installation of a ferrule body 4 that is compatible with the second limiting ring 8 as an example, in use, the third limiting ring 9 on the upper mold 3 and lower mold 2 is removed (if a larger diameter ferrule body 4 needs to be replaced, the second limiting ring 8 also needs to be removed). Then, the ferrule body 4 is placed within the second limiting ring 8 of the lower mold 2, and the upper mold 3 is then fastened onto the ferrule body 4, connecting and fixing the upper mold 3 and lower mold 2. The ferrule body 4 can then be used to process the indwelling needle. This mold uses multiple limiting rings, enabling one mold to adapt and fix multiple specifications of ferrules, thus improving its practicality.

[0029] By setting up a support platform 1, a lower mold 2 and an upper mold 3, and setting up a clamping assembly 5 including a first limiting ring 7, a second limiting ring 8 and a third limiting ring 9, this mold can be used in a corresponding combination to adapt to the fixed use of various melting head bodies 4, thereby improving the practicality of the mold. Example

[0030] like Figure 3 As shown, the first limiting ring 7 and the second limiting ring 8 are respectively provided with a first slot 10 and a second slot 12 of the same specification. Correspondingly, the second limiting ring 8 and the third limiting ring 9 are respectively provided with a first clip 11 and a second clip 13 of the same specification. A strong magnetic magnet is installed in both the first slot 10 and the second slot 12. When in use, the first clip 11 is inserted into the first slot 10, so that the first clip 11 is magnetically attracted and fixed, thereby connecting and fixing the second limiting ring 8 to the first limiting ring 7. The connection between the third limiting ring 9 and the second limiting ring 8 is similar and will not be described in detail here.

[0031] By setting the first card slot 10 and the second card slot 12, and installing the first card head 11 and the second card head 13, the first limiting ring 7, the second limiting ring 8 and the third limiting ring 9 are connected by magnetic attraction, which facilitates the assembly and disassembly of the clamping component 5. Example

[0032] like Figure 3-4 As shown, an arc-shaped groove 14 is provided on the top of the lower mold 2. The arc-shaped groove 14 is adapted to the first limiting ring 7. An overlapping part 15 is provided at both ends of the arc-shaped groove 14. An isolation protrusion 17 is provided between the overlapping parts 15. An overlapping joint 16 is provided on the first limiting ring 7. The overlapping joint 16 has a hole, and the overlapping part 15 has a threaded groove. In use, the overlapping joint 16 of the first limiting ring 7 is placed on the overlapping part 15. The inner side of the first limiting ring 17 abuts against the isolation protrusion 17. Then, a screw is passed through the overlapping joint 16 and screwed into the overlapping part 15 to fix the first limiting ring 7. The two first limiting rings 7 are naturally divided into clamping grooves 6 of corresponding widths through the isolation protrusion 17.

[0033] By setting the arc groove 14, the overlapping part 15, the overlapping joint 16 and the isolation protrusion 17, the first limiting ring 7 can be easily connected and fixed to the lower mold 2, and the first limiting ring 7 can be positioned to facilitate the formation of the clamping groove 6. Example

[0034] like Figure 5 As shown, an installation groove 18 is provided on the support platform 1, and the lower mold 2 is embedded in the installation groove 18. In use, the bottom end of the lower mold 2 is embedded in the installation groove 18, and then a long bolt 19 is screwed onto the side of the support platform 1 so that the end of the long bolt 19 presses tightly against the side of the lower mold 2, thereby fixing the lower mold 2 in the installation groove 18.

[0035] By setting the mounting groove 18 on the support platform 1, the lower mold 2 can be easily installed and positioned. Example

[0036] like Figure 4 As shown, a tapered groove 20 is provided on the side of the lower mold 2. The tapered groove 20 has a larger opening and a smaller inner opening. In use, the end of the long bolt 19 is screwed into the tapered groove 20. As the end of the bolt goes deeper into the tapered groove 20, the end of the long bolt 19 presses against the tapered groove 20, so that the position of the tapered groove 20 can be automatically aligned, thereby enabling the lower mold 2 to be automatically aligned when fixed.

[0037] By opening a tapered groove 20 on the side of the lower mold 2, the lower mold 2 can be automatically aligned when it is fixed, making the assembly more precise.

[0038] Working principle: Taking the installation of the ferrule body 4, which needs to be adapted to the second limiting ring 8, as an example, remove the third limiting ring 9 from the upper mold 3 and the lower mold 2. Then, place the ferrule body 4 inside the second limiting ring 8 of the lower mold 2, so that the side protrusion of the ferrule body 4 is embedded in the clamping groove 6. Then, fasten the upper mold 3 onto the ferrule body 4, connecting and fixing the upper mold 3 and the lower mold 2. The ferrule body 4 can then be used to process the indwelling needle. This mold uses multiple limiting rings that can be used in combination, enabling one mold to adapt and fix ferrules of various specifications, thus improving its practicality.
