Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[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 1-8 A single-out forming mold for producing base plates of magnesium alloy die casting 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. The fixed module 1 is provided with a casting port 14 for pouring molten metal. 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 magnesium alloy base plate workpiece 4. 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 magnesium alloy base plate workpiece 4. The fixed module 1 is connected to a die-casting forming mechanism 3 for forming and demolding the magnesium alloy base plate workpiece 4.

[0021] Four sets of limiting protrusions 13 are fixedly connected at the four corners of the fixed mold core 11 and are inserted into the moving mold core 21.

[0022] Four sets of limiting posts 23, which are inserted into the fixed module 1, are fixedly connected at the four corners of the moving module 2.

[0023] The lower edge of the limiting protrusion 13 and the upper edge of the limiting post 23 are provided with chamfers to serve as guides.

[0024] The die-casting molding mechanism 3 includes a first molding component 31, a second molding component 32, and a third molding component 33. The first molding component 31, which is used to perform molding and demolding operations on the first molding part 41 of the magnesium alloy base plate workpiece 4, is connected to the front end of the moving module 2. The second molding component 32, which is used to perform molding and demolding operations on the second molding part 42 of the magnesium alloy base plate workpiece 4, is connected to the rear end of the moving module 2. The third molding component 33, which is used to perform molding and demolding operations on the third molding part 43 of the magnesium alloy base plate workpiece 4, is connected to the right end of the moving module 2.

[0025] 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 protrusion 13 is inserted into the moving mold core 21, and the limiting post 23 is inserted into the fixed module 1 until the fixed mold core 11 and the moving mold core 21 abut against each other. At this time, the fixed mold forming groove 12 and the moving mold forming groove 22 form a cavity. Subsequently, the first forming component 31, the second forming component 32, and the third forming component 33 are inserted into the cavity to seal it. The injection mechanism of the die casting machine injects molten metal into the cavity through the casting port 14. Under the combined action of the cavity, the first forming component 31, the second forming component 32, and the third forming component 33, the forming operation of the first forming part 41, the second forming part 42, and the third forming part 43 of the magnesium alloy base plate workpiece 4 can be realized. After the molten metal is filled, the injection mechanism of the die casting machine will maintain the pressure for a period of time until the molten metal in the forming cavity solidifies. Then, the first forming component 31, the second forming component 32, and the third forming component 33 are reset, that is, the first forming component 31, the second forming component 32, and the third forming component 33 are respectively separated from the first forming part 41, the second forming part 42, and the third forming part 43 of the magnesium alloy base plate workpiece 4. The operation of the die casting machine causes the moving module 2 to separate from the fixed module 1. The magnesium alloy base plate workpiece 4 remains in the moving mold forming groove 22. The ejection mechanism of the die casting machine ejects the magnesium alloy base plate workpiece 4 from the moving mold forming groove 22.

[0026] The first forming component 31 includes a first forming push cylinder 311, a first connecting frame 312, a first copying push block 313, and a first limiting block 314. The outer shell of the first forming push cylinder 311 is fixedly connected to the front end of the moving module 2 through the first connecting frame 312. The output end of the first forming push cylinder 311 is fixedly connected to the first copying push block 313. The first copying push block 313 is used to perform forming operations on the first forming part 41 of the magnesium alloy base plate workpiece 4. The first limiting block 314 is fixedly connected to the inner wall of the front end of the moving module 2. The outer wall of the first copying push block 313 is slidably connected to the inner wall of the first limiting block 314.

[0027] The second forming component 32 includes a second forming push cylinder 321, a second connecting frame 322, a second contour push block 323, and a second limiting block 324. The outer shell of the second forming push cylinder 321 is fixedly connected to the rear 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 magnesium alloy base plate workpiece 4. The second limiting block 324 is fixedly connected to the inner wall of the rear end of the moving module 2. The outer wall of the second contour push block 323 is slidably connected to the inner wall of the second limiting block 324.

[0028] The third forming component 33 includes a third forming push cylinder 331, a third connecting frame 332, a third copying push block 333, and a third limiting block 334. The outer shell of the third forming push cylinder 331 is fixedly connected to the right 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 magnesium alloy base plate workpiece 4. The third limiting block 334 is fixedly connected to the inner wall of the right end of the moving module 2. The outer wall of the third copying push block 333 is slidably connected to the inner wall of the third limiting block 334.

[0029] In this utility model, when the fixed mold core 11 and the moving mold core 21 come into contact, the first forming push cylinder 311 on the first connecting frame 312 is activated, and with the cooperation of the first limiting block 314, it pushes the first copying push block 313 to move into the cavity. At the same time, the second forming push cylinder 321 on the second connecting frame 322 is activated, and with the cooperation of the second limiting block 324, it pushes the second copying push block 323 to move into the cavity. At the same time, the third forming push cylinder 331 on the third connecting frame 332 is activated, and with the cooperation of the third limiting block 334, it pushes the third copying push block 333 to move into the cavity. After a closed cavity is formed, the first forming push cylinder 311, the second forming push cylinder 321 and the third forming push cylinder 331 are closed. After the molten metal in the cavity solidifies, the first forming push cylinder 311, the second forming push cylinder 321, and the third forming push cylinder 331 are activated, driving the first copying push block 313, the second copying push block 323, and the third copying push block 333 to reset. This causes the first copying push block 313, the second copying push block 323, and the third copying push block 333 to detach from the first forming part 41, the second forming part 42, and the third forming part 43. Under the combined action of the cavity, the first copying push block 313, the second copying push block 323, and the third copying push block 333, the forming operation of the first forming part 41, the second forming part 42, and the third forming part 43 of the magnesium alloy base plate workpiece 4 can be realized.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
