[0036] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate way to form various embodiments. At the same time, the steps or actions in the method description can also be sequentially changed or adjusted in a way that is obvious to the person skilled in the art.

[0037] The numbers of components in this article, such as "first", "second", etc., are only used to distinguish the described objects, and have no technical meaning. Unless otherwise specified, "connection" and "coupling" in this application include direct and indirect connections (couplings).

[0038] As shown in Figure 1 and Figure 2 The three-dimensional twisted three-way rubber seal 8 is composed of hollow seal body one 81, hollow seal body two 82 and hollow seal body three 83. Due to the hollow three-way form, the difficulty of pulling out the mold core increases significantly. It is necessary to avoid damaging the rubber seal and ensure that the mold core can be easily taken out, which puts high requirements on the design of the mold core.

[0039] In addition, the design of the mold core of the three-dimensional twisted three-way rubber seal also needs to consider how to reasonably segment. Due to the complex structure, the overall manufacturing of the mold core is difficult, the cost is high, and it is not easy to demold. Therefore, it is necessary to segment it cleverly to reduce the manufacturing difficulty and improve the demolding efficiency. However, how to accurately position the segmented mold core to ensure seamless connection between each segment and thus guarantee the integrity and sealing performance of the rubber seal is also a technical problem that must be solved in the design process.

[0040] As shown in Figure 3 The mold core structure of the three-dimensional twisted three-way rubber seal is composed of mold core one 1, mold core two 2, mold core three 3, mold core four 4, mold core five 5, mold core six 6 and mold core seven 7.

[0042] Mold core one 1, mold core two 2 and mold core five 5 constitute the main structure. Mold core one 1 is broken at the circular arc tangent point, and a long hanging shaped positioning hole one 12 is processed at the segmented port.

[0043] Mold core two 2 is segmented into a small cuboid notch from the tangent point, and a long hanging shaped positioning pin one 24 is processed at the end surface to connect and position with mold core one 1, while a long hanging shaped positioning hole two 23 is processed on the side surface to connect with mold core five 5.

[0044] Mold core five 5 is segmented into a small cuboid notch from the tangent point on both sides, and a long hanging shaped positioning pin three 53 is processed at the farthest end surface to connect and position with mold core two 2.

[0045] The middle part of the mold core (mold core three 3, mold core four 4, mold core six 6, mold core seven 7) is segmented into four pieces from the four tangent points and the middle position, ensuring that the size of the segmented mold core is smaller than the size of the hollow part of the product, facilitating demolding.

[0046] The mold core three 3 and the mold core four 4 are positioned by connecting two circular positioning pins two 42 on the mold core four 4 with two circular positioning holes three 31 on the mold core three 3.

[0047] The mold core six 6 and the mold core seven 7 are positioned by connecting two circular positioning pins six 71 on the mold core seven 7 with two circular positioning holes five 61 on the mold core six 6. Two circular positioning pin holes on the rear end face of the mold core seven 7 are positioned by cooperating with the positioning pins on the mold core five 5.

[0048] The mold core three 3 and the mold core six 6 are connected with the mold core five 5 through the mold core four 4 and the mold core seven 7 respectively, so as to form a stable intermediate structure.

[0049] The mold core one 1, the mold core two 2 and the mold core five 5 are used as main body supports, and long hanging positioning pins are designed, so as to ensure the stability and positioning accuracy of the whole mold core.

[0050] The other end of the mold core one 1 is processed into an end positioning plug block one 11, the end of the mold core two 2 is processed into an end positioning plug block two 21, and the end of the mold core five 5 is processed into an end positioning plug block three 56. Long hanging positioning pins are processed on the plug blocks, and long hanging positioning pin holes are processed on the mold core, so as to ensure the positioning accuracy of the three mold cores and the accuracy of the product wall thickness size.

[0051] Positioning pins four 54 and positioning pins five 55 are arranged at the bottom of the gap two 51 and the gap three 52 of the mold core five 5 respectively, and are positioned by cooperating with the positioning holes on the mold core four 4 and the mold core seven 7, so as to ensure the accurate installation of the intermediate mold core.

[0052] The mold core structure realizes the accurate molding of the complex three-dimensional twisted three-way rubber sealing element through the ingenious segmentation and positioning design. The combination of the long hanging positioning pins and the circular positioning pins ensures the accurate positioning between the mold cores, simplifies the processing process, and reduces the cost. The mold core structure is easy to operate, reduces the waste rate, improves the qualified rate and production efficiency, and has significant economic benefits.
