[0019] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0020] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-9 A die-casting mold for aluminum alloy cast pipe includes a fixed module 1 and a moving module 2. The fixed module 1 is fixedly connected to the fixed shape base plate of the die-casting machine, and the moving module 2 is fixedly connected to the moving shape base plate of the die-casting machine. It also includes a die-casting forming mechanism 3, on which the fixed module 1 is connected for forming and demolding the aluminum alloy cast pipe workpiece 4.

[0021] The lower end of the fixed module 1 is fixedly connected to a fixed mold core 11, and the fixed mold core 11 is provided with a fixed mold forming groove 12 for forming the aluminum alloy cast pipe workpiece 4.

[0022] The upper end of the moving module 2 is fixedly connected to the moving mold core 21, and the moving mold core 21 is provided with a moving mold forming groove 22 for forming the aluminum alloy cast pipe workpiece 4.

[0023] The fixed module 1 is provided with a casting port 14 for pouring molten metal.

[0024] Four sets of limiting posts 13, which are inserted into the moving module 2, are fixedly connected at the four corners of the lower end of the fixed module 1.

[0025] Four sets of limiting protrusions 23 that are inserted into the fixed mold core 11 are fixedly connected at the four corners of the upper end of the moving mold core 21.

[0026] The lower edge of the limiting post 13 and the upper edge of the limiting protrusion 23 are provided with chamfers that serve as guides.

[0027] The die-casting molding mechanism 3 includes a first molding component 31, a second molding component 32, a third molding component 33, and a fourth molding component 34.

The third molding component 33, which is used to perform molding and demolding operations on the third molding part 43 of the aluminum alloy cast tube workpiece 4, is connected to the front end of the moving module 2. The fourth molding component 34, which is used to perform molding and demolding operations on the fourth molding part 44 of the aluminum alloy cast tube workpiece 4, is connected to the rear end of the moving module 2.

[0028] In this utility model, the operation of the die casting machine causes the moving module 2 to move towards the fixed module 1. During the movement, the limiting post 13 is inserted into the moving module 2, and the limiting protrusion 23 is inserted into the fixed mold core 11 until the fixed mold core 11 and the moving mold core 21 abut against each other. At this time, a cavity is formed inside the fixed mold forming groove 12 and the moving mold forming groove 22. Subsequently, the second forming component 32, the third forming component 33, and the fourth forming component 34 are inserted into the cavity to seal it.

The operation of the die-casting machine causes the moving module 2 to separate from the fixed module 1. The aluminum alloy cast tube workpiece 4 remains in the moving mold forming groove 22. The ejection mechanism of the die-casting machine ejects the aluminum alloy cast tube workpiece 4 from the moving mold forming groove 22.

[0030] The second forming component 32 includes a second forming push cylinder 321, a second connecting frame 322, and a second contour push block 323. The outer shell of the second forming push cylinder 321 is fixedly connected to the left end of the moving module 2 through the second connecting frame 322. The output end of the second forming push cylinder 321 is fixedly connected to the second contour push block 323. The second contour push block 323 is used to perform forming operations on the second forming part 42 of the aluminum alloy cast tube workpiece 4. The left end of the moving module 2 is provided with a second limiting groove that is slidably connected to the outer wall of the second contour push block 323.

[0031] The third forming component 33 includes a third forming push cylinder 331, a third connecting frame 332, and a third copying push block 333. The outer shell of the third forming push cylinder 331 is fixedly connected to the front end of the moving module 2 through the third connecting frame 332. The output end of the third forming push cylinder 331 is fixedly connected to the third copying push block 333. The third copying push block 333 is used to perform forming operations on the third forming part 43 of the aluminum alloy cast tube workpiece 4. The front end of the moving module 2 is provided with a third limiting groove that is slidably connected to the outer wall of the third copying push block 333.

[0032] The outer diameter of the third copying pusher 333 is the same as the inner diameter of the third forming part 43.

[0033] The fourth forming component 34 includes a fourth forming push cylinder 341, a fourth connecting frame 342, and a fourth contour push block 343. The outer shell of the fourth forming push cylinder 341 is fixedly connected to the rear end of the moving module 2 through the fourth connecting frame 342. The output end of the fourth forming push cylinder 341 is fixedly connected to the fourth contour push block 343. The fourth contour push block 343 is used to perform forming operations on the fourth forming part 44 of the aluminum alloy cast tube workpiece 4. The rear end of the moving module 2 is provided with a fourth limiting groove that is slidably connected to the outer wall of the first contour push block 313.

[0034] The outer diameter of the fourth copying pusher 343 is the same as the inner diameter of the fourth forming part 44.

[0035] In this utility model, when the fixed mold core 11 abuts against the moving mold core 21, the first forming push cylinder 311 on the first connecting frame 312 is activated, pushing the first copying push block 313 into the cavity with the cooperation of the first limiting groove. At the same time, the second forming push cylinder 321 on the second connecting frame 322 is activated, pushing the second copying push block 323 into the cavity with the cooperation of the second limiting groove. At the same time, the third forming push cylinder 331 on the third connecting frame 332 is activated, pushing the third copying push block 333 into the cavity with the cooperation of the third limiting groove. At the same time, the fourth forming push cylinder 341 on the fourth connecting frame 342 is activated, pushing the fourth copying push block 343 into the cavity with the cooperation of the fourth limiting groove. After a closed cavity is formed, the first forming push cylinder 311, the second forming push cylinder 321, the third forming push cylinder 331 and the fourth forming push cylinder 341 are closed. After the molten metal in the cavity solidifies, the first forming push cylinder 311, the second forming push cylinder 321, the third forming push cylinder 331, and the fourth forming push cylinder 341 are activated, driving the first copying push block 313, the second copying push block 323, the third copying push block 333, and the fourth copying push block 343 to reset. This causes the first copying push block 313, the second copying push block 323, the third copying push block 333, and the fourth copying push block 343 to detach from the first forming part 41, the second forming part 42, the third forming part 43, and the fourth forming part 44. Under the combined action of the cavity, the first copying push block 313, the second copying push block 323, the third copying push block 333, and the fourth copying push block 343, the forming operation of the first forming part 41, the second forming part 42, the third forming part 43, and the fourth forming part 44 of the aluminum alloy cast tube workpiece 4 can be realized.
