[0019] According to one embodiment of the present invention, in conjunction with the appendix Figure 1-4 As shown.

[0020] A die-casting apparatus for producing automotive parts includes a support platform 1. A support base 2 is fixedly mounted on the upper surface of the support platform 1. Two driving components 6 are fixedly mounted on the outer surface of the support base 2. A sliding seat 3 is provided above the support platform 1. A moving mold 4 is fixedly mounted on one side of the sliding seat 3. A fixed mold 5 is fixedly mounted on one side of the support base 2. A sliding cover 7 is fixedly mounted on one side of the sliding seat 3. A driving cover 8 is fixedly mounted on one side of the sliding cover 7. A variable frequency motor 9 is fixedly mounted on the outer surface of the driving cover 8. A transmission screw 13 is fixedly mounted on the output end of the variable frequency motor 9. A threaded transmission block 10 is threadedly connected to the outer surface of the transmission screw 13. A sliding plate 11 is fixedly mounted on one side of the threaded transmission block 10. A pressure sensor, such as a thin-film pressure sensor, is provided on one side of the sliding plate 11. The sensor is connected to the external control cabinet via a signal line. When the sliding plate 11 contacts the sliding seat 3, the pressure sensor feeds back the pressure value to the control cabinet in real time. The control cabinet controls the variable frequency motor 9 to stop operating according to the preset threshold, realizing closed-loop control of automatic feeding. Two feeding holes 14 are opened on one side of the sliding seat 3 and one side of the moving mold 4. Two feeding push rods 15 are fixedly installed on one side of the sliding plate 11. The bottom surface of the support platform 1 is provided with a feeding port 16. By moving the feeding push rods 15 inside the feeding holes 14, the automotive parts on the surface of the moving mold 4 can be pushed, which will assist in feeding. In addition, the electrical components of this application are all common electrical equipment in the prior art. This application will not elaborate on their models or internal structures. Moreover, they need to be connected to the circuit of the external control cabinet.

[0021] In this embodiment, as a further solution of the present invention: the top ends of the two feeding rods 15 extend into the interior of the two feeding holes 14 respectively, the outer surface of the sliding plate 11 is slidably connected to the inner wall of the sliding cover 7, the driving component 6 includes two fixing plates 601 fixedly installed on the outer surface of the support base 2, an electric cylinder 602 is fixedly installed on one side of each of the two fixing plates 601, a connecting plate 603 is fixedly installed on the telescopic end of each of the two electric cylinders 602, and the side of each connecting plate 603 that is close to each other is fixedly installed on the outer surface of the sliding seat 3. By fixing the fixing plates 601 above the support base 2, the electric cylinders 602 can be installed. The telescopic end of the electric cylinders 602 drives the sliding seat 3 to move linearly along the surface of the slide rail 21 and the slide rod 19, which can realize the precise mold closing and separation of the moving mold 4 and the fixed mold 5.

[0022] In this embodiment, two circular holes 18 are formed on the outer surface of the sliding seat 3, and two sliding holes 20 are formed on the bottom surface of the sliding seat 3. Two sliding rods 19 are fixedly installed on one side of the support seat 2. The outer surfaces of the two sliding rods 19 are slidably connected to the inner walls of the two circular holes 18 respectively. Two slide rails 21 are fixedly installed on the upper surface of the support platform 1. The outer surfaces of the two slide rails 21 are slidably connected to the inner walls of the two sliding holes 20 respectively. Through the cooperation between the sliding holes 20 and the slide rails 21, and the cooperation between the circular holes 18 and the sliding rods 19, the moving mold 4 is ensured to move smoothly and the mold closing deviation is reduced.

[0023] In this embodiment, a rectangular hole 12 is provided on one side of the sliding cover 7. The inner wall of the rectangular hole 12 is slidably connected to the outer surface of the threaded transmission block 10. The rectangular hole 12 allows the threaded transmission block 10 to move smoothly inside it, avoiding rotation. A liquid injection hole 17 is provided on one side of the support base 2. One end of the liquid injection hole 17 is connected to the injection end of the fixed mold 5. Two water-cooling connectors 22 are fixedly connected to the outer surface of the fixed mold 5. The liquid injection hole 17 allows molten metal raw materials to be directly injected into the fixed mold 5. In addition, the water-cooling connectors 22 on the surface of the fixed mold 5 allow for rapid cooling of the metal raw materials, shortening the solidification time and improving production efficiency.

[0024] Working principle: First, molten metal raw material is injected into the fixed mold 5 through the injection hole 17 on one side of the support seat 2. Then, the drive component 6 starts to work. The two electric cylinders 602 in the drive component 6 drive the connecting plate 603 to push the sliding seat 3 to move, which can make the moving mold 4 on one side of the sliding seat 3 approach the fixed mold 5 and close, completing the mold closing action before die casting. Then, the two water cooling joints 22 connected to the outer surface of the fixed mold 5 can be connected to cool liquid, which can cool the fixed mold 5 and accelerate the solidification and forming of the metal raw material.

[0025] After the metal raw material cools and solidifies in the mold, the electric cylinder 602 extends and drives the sliding seat 3 to reset and move, which can separate the moving mold 4 from the fixed mold 5. Then, the variable frequency motor 9 starts, which can drive the transmission screw 13 to rotate at its output end. This can drive the threaded transmission block 10 to slide inside the rectangular hole 12, and cause the threaded transmission block 10 to push the sliding plate 11. This allows the ejector rod 15 on one side of the sliding plate 11 to extend along the ejector hole 14, which can eject the formed automotive parts from the surface of the moving mold 4. Then, the automotive parts fall through the ejector port 16 on the bottom surface of the support table 1, completing one die-casting production process.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
