[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention 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, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] Furthermore, the terms "parallel" and "perpendicular" do not imply that components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted.

[0044] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0045] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] Example

[0047] Existing multi-way hose molds include main pipe molds and branch pipe molds. Since most multi-way hoses currently have straight main pipes and branch pipes, their corresponding main pipe molds and branch pipe molds are also straight pipes. In this case, the main pipe mold and branch pipe mold are usually connected by bolts (threaded holes are opened on the side wall of the main pipe mold, and bolts are installed at the end of the branch pipe mold). The bolts and threaded holes are engaged by rotating the branch pipe mold. During the demolding process, the branch pipe mold is rotated in the opposite direction to separate from the main pipe mold.

[0048] However, with the diversification of products, the shapes of multi-way hoses are becoming increasingly diverse, especially in the automotive industry, where internal piping is complex. To avoid these complexities, multi-way hoses are often irregularly shaped. When both the main pipe and branch pipes of a multi-way hose are irregularly shaped (e.g....), Figure 1 At this point, the main pipe mold and branch pipe mold should also adopt irregular structure. However, the irregular structure cannot effectively connect the main pipe mold and branch pipe mold through the above bolt connection method, which increases the difficulty of processing irregular multi-port hoses. In particular, when both the main pipe mold and the branch pipe mold are irregular, the processing difficulty is even greater. At present, there is no specific solution in the industry to solve this problem.

[0049] Furthermore, due to the diversity of products, the angle between the main pipe and the branch pipe is uncertain and is not always the ideal 90°, but varies randomly. When the angle between the main pipe mold and the branch pipe mold is not 90°, the end face of the branch pipe mold that contacts the branch pipe mold is an inclined plane. Therefore, the above-mentioned bolt connection method cannot be used.

[0050] For the reasons mentioned above, please refer to Figures 1-13 This embodiment provides a multi-port hose mold, including: a main pipe mold 100, a branch pipe mold 200, a first locking mechanism 300, a tension rope 400, and a second locking mechanism 500.

[0051] Please refer to Figure 9 , Figure 10The main pipe mold 100 has a first movable channel 110 along its length to facilitate the passage of the tension rope 400, and a connecting hole 120 is provided on the side wall of the main pipe mold 100. The end of the tension rope 400 passes through the first movable channel 110 and the connecting hole 120 in sequence and is connected to the end of the branch pipe mold 200. The tension rope 400 can move along the length of the first movable channel 110 to tighten the branch pipe mold 200 and make it fit tightly against the main pipe mold 100. The first locking mechanism 300 is connected to the end of the tension rope 400 away from the branch pipe mold 200 to lock the tension rope 400 along the axial direction of the tension rope 400.

[0052] It should be noted that since the main tube mold 100 may be irregular in shape, the length direction of the main tube mold 100 refers to the outline direction of the main tube mold 100.

[0053] Another point to note is that the position of the connecting hole 120 can be determined according to the actual installation position of the branch pipe mold 200. In the actual processing, first determine the installation position between the branch pipe mold 200 and the main pipe mold 100, and then open the connecting hole 120.

[0054] Another point to note is that the first locking mechanism 300 locks the tension rope 400 in the following way: when the tension rope 400 drives the branch pipe mold 200 to the ideal position, the first locking mechanism 300 can lock the tension rope 400, so that the tension rope 400 and the main pipe mold 100 are kept in a fixed position, thereby preventing the tension rope 400 from resetting.

[0055] By pulling the tension rope 400, the branch pipe mold 200 can be moved toward the main pipe mold 100 until the end of the branch pipe mold 200 is in contact with the side wall of the main pipe mold 100. In addition, the tension rope 400 is locked by the first locking mechanism 300, thereby achieving fixation.

[0056] Through the above design, the main pipe mold 100 and the branch pipe mold 200 can be quickly fitted together by pulling the tension rope 400 to achieve connection. The tension rope 400 is locked by the first locking mechanism 300, thereby keeping the main pipe mold 100 and the branch pipe mold 200 in a fixed position.

[0057] In general, the multi-port hose mold provided in this embodiment of the invention can make the main pipe mold 100 and the branch pipe mold 200 fit together by tensioning, thereby realizing the rapid connection and separation of the main pipe mold 100 and the branch pipe mold 200, which greatly improves work efficiency and ease of operation.

[0058] Furthermore, the main pipe mold 100 has a first end 130 and a second end 140, and a first locking mechanism 300 is provided at the first end 130. The central axis of the first end 130 and the branch pipe mold 200 have an included angle A, and the included angle A is not less than 90°.

[0059] It should be noted that, due to the uncertainty of the included angle between the main pipe mold 100 and the branch pipe mold 200, in order to ensure that the tensioning rope 400 exerts a greater tensioning force on the branch pipe mold 200, in actual implementation, the first locking mechanism 300 is preferentially set at the end with a larger included angle with the branch pipe mold 200, so that the tensioning angle of the tensioning rope 400 is not less than 90°, thus ensuring a stronger tensioning force.

[0060] In this embodiment, please refer to Figure 12 The first locking mechanism 300 includes a tensioning part 310 and a support part 320. The support part 320 is located at the end of the main mold 100 and has a second active channel 321 that matches the first active channel 110.

[0061] The end of the tension rope 400 away from the branch pipe mold 200 passes through the first movable channel 110 and is connected to the tensioning part 310; along the axial direction of the support part 320, the tensioning part 310 is movably connected to the support part 320; so as to pull the tension rope 400 to move along the length direction of the first movable channel 110.

[0062] With this design, the end of the tension rope 400 can be connected to the tensioning part 310, so that as the tensioning part 310 moves along the axial direction of the support part 320, the tension rope 400 moves along the length direction of the first movable channel 110, thereby tightening the branch pipe mold 200.

[0063] In some embodiments, the tension rope 400 can be connected to one end of the tensioning part 310 near the main pipe mold 100, so that when the tensioning part 310 moves toward the main pipe mold 100, the branch pipe mold 200 is tightened, and the reverse movement is used to loosen the branch pipe mold 200.

[0064] In other embodiments, the tension rope 400 may be connected to the end of the tensioning part 310 away from the main pipe mold 100, so that when the tensioning part 310 moves toward the main pipe mold 100, the branch pipe mold 200 is relaxed, and when it moves in the opposite direction, the branch pipe mold 200 is tightened.

[0065] In this embodiment, the tensioning part 310 has a mating hole 311 along its circumference that matches the support part 320. A locking part 312 is provided at the end of the tensioning part 310 away from the main mold 100, and the tensioning rope 400 is connected to the locking part 312. The locking part 312 has an installation notch 313 that matches the tensioning rope 400, and a limiting block 410 is provided at the end of the tensioning rope 400. A locking nut 314 is installed at the end of the tensioning part 310 near the main mold 100, and the support part 320 has a first thread 322 that engages with the locking nut 314.

[0066] It should be noted that the hole 311 is movably connected to the support part 320 along the circumferential direction of the support part 320, ensuring that the tensioning part 310 can move axially along the support part 320 and rotate circumferentially along the support part 320.

[0067] Another point to note is that the depth direction of the mounting notch 313 points to the center of the locking part 312, and the width of the mounting notch 313 is greater than the diameter of the tension rope 400, ensuring that the tension rope 400 can smoothly enter the mounting notch 313, and that the tension rope 400 can rotate relative to the mounting notch 313 when the tensioning part 310 rotates.

[0068] Another point to note is that the diameter of the limiting block 410 is larger than the width of the installation notch 313, thereby limiting the tension rope 400.

[0069] With the above design, the tightening part 310 can be rotated to drive the locking nut 314 to rotate. The locking nut 314 engages with the first thread 322, thereby realizing the axial movement of the tightening part 310 along the support part 320. Furthermore, through the threaded connection, the position of the tightening part 310 can be fixed while adjusting its position. By moving the tightening part 310 away from the main mold 100, the tightening rope 400 moves synchronously, thereby tightening the branch mold 200 so that the end of the branch mold 200 fits tightly against the side wall of the main mold 100. When demolding, simply rotate the tightening part 310 in the opposite direction.

[0070] In this embodiment, in order to ensure the connection between the tension rope 400 and the branch pipe mold 200, a second locking mechanism 500 is specially added. The second locking mechanism 500 is located on the branch pipe mold 200 to fix the tension rope 400 to the branch pipe mold 200.

[0071] Specifically, the branch pipe mold 200 has a third movable channel 210 along its length to facilitate the passage of the tension rope 400, and the second locking mechanism 500 is located at the end of the branch pipe mold 200 away from the main pipe mold 100.

[0072] Please refer to Figure 13The second locking mechanism 500 includes a first limiting part 510 and a second limiting part 520. The first limiting part 510 is located at the end of the branch pipe mold 200 away from the main pipe mold 100, and the first limiting part 510 has a central hole 530 that matches the third movable channel. The end of the tension rope 400 passes through the third movable channel 210 and the central hole 530 and is detachably connected to the second limiting part 520.

[0073] In this embodiment, the end of the tension rope 400 near the branch pipe mold 200 is provided with a receiving part 420 that matches the third movable channel 210 and the central hole 530. The receiving part 420 has an insertion hole 430 that matches the second limiting part 520. The central axis of the insertion hole 430 and the central axis of the receiving part 420 have an angle. The second limiting part 520 can be inserted into the insertion hole 430.

[0074] It should be noted that in this embodiment, the diameters of the first movable channel 110, the second movable channel 321, the third movable channel 210, and the central hole 530 are the same and all larger than the diameter of the tension rope 400, ensuring that the tension rope 400 can move normally without obstruction.

[0075] Another point to note is that the tension rope 400 and the receiving part 420 can be connected by various conventional methods such as welding and snap-fitting, which will not be elaborated here.

[0076] In actual installation, the end of the tension rope 400 can be connected to the receiving part 420 first. Then, the receiving part 420 passes through the third movable channel 210 and the center hole 530 in sequence. Then, the second limiting part 520 is inserted into the insertion hole 430. The tension rope 400 and the branch pipe mold 200 are detachably connected through the interaction of the second limiting part 520 and the first limiting part 510. This detachable connection method facilitates the disassembly of the branch pipe mold 200 during demolding.

[0077] In addition, in some other embodiments, the tension rope 400 can be directly welded to the end of the branch pipe mold 200 by welding; in this way, the tension rope 400 can be separated from the first locking mechanism 300 during demolding, and then the tension rope 400 can be pulled out.

[0078] The installation principle of a multi-port hose mold is as follows: First, insert one end of the tension rope 400 into the installation notch 313, then pass the other end of the tension rope 400 through the second movable channel 321, the first movable channel 110, the third movable channel 210 and the center hole 530 in sequence and connect it to the receiving part 420, and then insert the second limiting part 520 into the insertion hole 430.

[0079] During demolding, first remove the second limiting part 520 from the insertion hole 430, pull the branch pipe mold 200 to demold, and then pull the main pipe mold 100 to demold.

[0080] The working principle of a multi-port hose mold is as follows: First, rotate the tensioning part 310, which drives the locking nut 314 to rotate synchronously. The locking nut 314 engages with the first thread 322, thereby causing the tensioning part 310 to move away from the main pipe mold 100. This synchronously drives the tensioning rope 400 to move synchronously, and drives the branch pipe mold 200 to move towards the connecting hole 120 until the end face of the branch pipe mold 200 is close to the side wall of the main pipe mold 100. When demolding, simply rotate the tensioning part 310 in the opposite direction.

[0081] In summary, the present invention can make the main pipe mold 100 and the branch pipe mold 200 fit together by tensioning, thereby realizing the rapid connection and separation of the main pipe mold 100 and the branch pipe mold 200, which greatly improves work efficiency and ease of operation.

[0082] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
