[0040] One or both of the clamping table 120 and the heating module 130 are movably connected to the workbench 110; a plurality of molds 140 are connected to the clamping table 120, and the molds 140 are used to clamp the catheter to be formed;

[0041] The clamping table 120 or the heating module 130 is used to move relative to the workbench 110 under the action of an external force, so that the heating module 130 is in a position where the plurality of molds 140 can be heated.

[0042] Please refer to Figure 1-Figure 5 The working principle of the catheter tip molding device 100 is:

[0043] The catheter tip molding device 100 includes a workbench 110, a clamping table 120, a heating module 130 and a plurality of molds 140; wherein the plurality of molds 140 are all connected to the clamping table 120, and the molds 140 are used to clamp the catheter to be molded, and one or both of the clamping table 120 and the heating module 130 are movably connected to the workbench 110; thus, when the catheter is molded, the plurality of catheters to be molded can be respectively loaded into the plurality of molds 140, and the clamping table 120 or the heating module 130 is moved relative to the workbench 110, so that the heating module 130 is in a position where the plurality of molds 140 can be heated, thereby the plurality of molds 140 can be heated simultaneously by the heating module 130, and then the plurality of catheters to be molded can be molded simultaneously, thereby the tips of the catheters can be molded in batches, thereby shortening the processing cycle of the catheters, improving the processing efficiency, and reducing the processing cost of the catheter tips.

[0044] It should be noted that, from the above content, it can be seen that when configuring the clamping table 120 and the heating module 130, one or both of the clamping table 120 and the heating module 130 can be movably connected to the workbench 110. In the present embodiment, the clamping table 120 is fixedly connected to the workbench 110, while the heating module 130 is movably connected to the workbench 110. For illustration; in other embodiments of the present utility model, the clamping table 120 can be movably connected to the workbench 110, while the heating module 130 is fixedly connected to the workbench 110, or both the clamping table 120 and the heating module 130 can be movably connected to the workbench 110.

[0045] For further information, please refer to Figure 1-Figure 5In this embodiment, when configuring the mold 140, the purpose is to load the catheter to be formed into the mold 140, and under the heating action of the heating module 130 on the mold 140, the end of the catheter to be formed in the mold 140 is formed into a preset tip style. Therefore, when configuring the mold 140, the molding cavity in the mold 140 can be set according to the required tip style. Specifically, each mold 140 includes a first mold body 141 and a second mold body 142. When the first mold body 141 and the second mold body 142 are molded together, a molding cavity for the tip of the molded catheter is formed; one of the first mold body 141 and the second mold body 142 is fixedly connected to the clamping table 120, and the other is movably connected to the clamping table 120.

[0046] Thus, by setting up the structure of the mold 140 in this way, during use, taking the first mold body 141 as being fixedly connected to the clamping table 120 and the second mold body 142 as being movably connected to the clamping table 120, by adjusting the position of the second mold body 142, the first mold body 141 and the second mold body 142 can be separated from each other, so as to facilitate taking out the formed catheter or putting in the catheter to be formed, that is, it is easy to simplify the operation of combining and separating the first mold body 141 and the second mold body 142. It should also be noted that in this embodiment, when setting up the mold 140, the cross section of the end of the mold 140 facing the heating module 130 can be tapered, that is, from the direction of the heating module 130 toward the clamping table 120, the outer diameter of the end of the mold 140 facing the heating module 130 gradually increases.

[0047] In accordance with the structure of the above-mentioned mold 140, the clamping table 120 is provided with a plurality of mounting grooves 121, and each mounting groove 121 is matched with a first mold body 141 or a second mold body 142. Moreover, in the present embodiment, when installing the first mold body 141 and the second mold body 142, the first mold body 141 and the second mold body 142 are rotatably connected so that the second mold body 142 can move relative to the clamping table 120. Therefore, the mold 140 also includes a rotating hinge 143, and the first mold body 141 is rotatably connected to the second mold body 142 through the rotating hinge 143. In accordance with the above-mentioned structure, in order to facilitate the installation of the above-mentioned mold 140, the clamping table 120 is provided with a plurality of receiving grooves 122, each receiving groove 122 corresponds to a mounting groove 121, and the receiving groove 122 receives the rotating hinge 143 of the mold 140 located in the corresponding mounting groove 121.

[0048] In summary, when configuring the clamping table 120, the present embodiment adopts a method of configuring a plurality of installation grooves 121 and a plurality of receiving grooves 122 on the clamping table 120, and each installation groove 121 corresponds to a receiving groove 122. Therefore, when installing the above-mentioned mold 140, its first mold body 141 can be installed in the installation groove 121. At the same time, the rotating hinge 143 that rotatably connects the first mold body 141 and the second mold body 142 is located in the corresponding receiving groove 122, thereby simplifying the installation steps of the mold 140 and improving its installation efficiency.

[0049] For further information, please refer to Figure 1-Figure 7 In this embodiment, when configuring the heating module 130, the heating module 130 includes a heating platform 131 and a plurality of heating units 132; the plurality of heating units 132 are connected to the heating platform 131, and each heating unit 132 is formed with a heating cavity 135, and each heating cavity 135 is used to heat a corresponding mold 140.

[0050] Among them, it can be known from the above content that this embodiment adopts a method in which the heating module 130 is movably connected to the workbench 110. Therefore, during use, the heating module 130 can be moved so that the heating module 130 can heat multiple molds 140 at the same time. In this process, since the heating module 130 includes a heating table 131 and multiple heating units 132, during the activity, each heating cavity 135 can be moved to a position corresponding to heating a mold 140 by moving the heating table 131.

[0051] It should be noted that, from the foregoing content, it can be seen that in the present embodiment, when configuring the mold 140, the end of the mold 140 close to the heating module 130 is made into a variable diameter, that is, the cross-section thereof can be made conical, and then when the mold 140 moves toward the corresponding heating cavity 135, the end of the mold 140 can be made to extend into the heating cavity 135, and the mold 140 is locked by the end of the mold 140 being abutted against the port or inner wall of the heating cavity 135, thereby preventing the first mold body 141 and the second mold body 142 from moving in the direction of mold separation, thereby ensuring the molding quality.

[0052] In the process of heating the mold 140 by the heating unit 132, in order to improve the quality of heating and molding, the heating module 130 includes a heating sleeve 133 and a heating copper sleeve 134; the heating copper sleeve 134 forms a heating cavity 135, and the heating sleeve 133 is sleeved outside the heating copper sleeve 134. The setting of the heating sleeve 133 can generate heat, and the heat generated by the heating sleeve 133 is uniformly transferred to the mold 140 through the heating copper sleeve 134, so that the conduit in the mold 140 is uniformly heated to improve the molding quality.

[0053] Based on the above structural setting, since the present embodiment adopts a method in which the heating module 130 and the workbench 110 are movably connected, the catheter tip molding device 100 further includes a guide rail 150 and a slider; the guide rail 150 is connected to the workbench 110, the slider is slidably matched with the guide rail 150, and the slider is connected to the heating platform 131; wherein, the heating platform 131 is provided with a clearance groove 136 for accommodating the guide rail 150. With such a setting, the movement of the heating platform 131 can be guided by the installation of the guide rail 150, and since the bottom of the heating platform 131 is provided with a clearance groove 136 for accommodating the guide rail 150, it is possible to avoid interference between the bottom of the heating platform 131 and the guide rail 150 during the movement of the heating platform 131.

[0054] For further information, please refer to Figure 1-Figure 8 In this embodiment, in order to improve the efficiency of molding and facilitate the automation of molding, the catheter tip molding device 100 further includes a driving module 160 connected to the workbench 110, and the driving module 160 is in transmission connection with the heating platform 131. The driving module 160 can adopt a cylinder or hydraulic cylinder structure, or an electric telescopic rod structure, and the movement direction of its active end is consistent with the extension direction of the guide rail 150; and in order to control the heating state of the heating sleeve 133, the catheter tip molding device 100 further includes a heating console 170 connected to the workbench 110, the heating console 170 is electrically connected to the plurality of heating units 132, and the driving module 160 is connected to the heating console 170. It should be noted that a heating control panel is provided in the heating console 170, which is electrically connected to the plurality of heating sleeves 133 and can be controlled by the control buttons on the heating console 170. At the same time, a corresponding display structure can be configured on the heating console 170 to display the heating molding state.
