[0015] Embodiment 1 of this utility model: An injection molding device for connecting a water pipe in-mold threaded joint mechanism includes a device body 1, a mold 2 mounted on the device body 1, and an in-mold threaded joint structure 3 mounted on the device body 1. The in-mold threaded joint structure 3 includes a drive device 8, which is mounted on the device body 1. A first gear 6 is mounted on the output shaft of the drive device 8. The first gear 6 meshes with a second gear 5, which is mounted on the device body 1. The second gear 5 meshes with a third gear 4, which is mounted on the device body 1. The third gear 4 is coaxially fixedly connected to a threaded section 10 and a connecting rod 11. The threaded section 10 is located on one side of the third gear 4, and the connecting rod 11 is located on the other side of the third gear 4. The end of the connecting rod 11 has a toothed section 12, which faces the toothed section of the mold 2 where the water pipe is connected.

[0016] Example 2: An injection molding device for connecting a water pipe in-mold threaded joint mechanism includes a device body 1, a mold 2 mounted on the device body 1, and an in-mold threaded joint structure 3 mounted on the device body 1. The in-mold threaded joint structure 3 includes a drive device 8, which is mounted on the device body 1. A first gear 6 is mounted on the output shaft of the drive device 8. The first gear 6 meshes with a second gear 5, which is mounted on the device body 1. The second gear 5 meshes with a third gear 4, which is mounted on the device body 1. The third gear 4 is coaxially fixedly connected to a threaded section 10 and a connecting rod 11. The threaded section 10 is located on one side of the third gear 4, and the connecting rod 11 is located on the other side of the third gear 4. The end of the connecting rod 11 has a toothed section 12, which faces the toothed section of the mold 2 where the water pipe is connected.

[0017] The device body 1 includes a first mounting plate 7, on which a drive device 8 is mounted. The drive device 8 is located on one side of the first mounting plate 7, and a first gear 6 is located on the other side of the first mounting plate 7. The device body 1 also includes a second mounting plate 9, which has a threaded hole, and the threaded section 10 is located within the threaded hole. The width of the second gear 5 is greater than that of the third gear 4, and the width difference between the second gear 5 and the third gear 4 is equal to the length of the toothed section 12.

[0018] The working principle of one embodiment of this utility model is as follows: In use, the connecting rod 11 is located inside the mold 2, serving as part of the mold. The internal thread connecting the water pipe is generated by the toothed section 12, and the external thread connecting the water pipe is generated by the mold itself. The toothed section 12 and the mold 2 together define the space for injecting material, thereby generating the internal thread connecting the water pipe. After completion, the driving device 8 drives the first gear 6 to rotate, the first gear 6 drives the second gear 5 to rotate, the second gear 5 drives the third gear 4 to rotate, and the third gear 4 drives the threaded section 10 to rotate. After the threaded section 10 rotates, it enters the threaded hole on the second mounting plate 9, thereby completing the separation of the product from the connecting rod 11, and then normal demolding is performed.
