Description

[0001] This application is a divisional application of the application filed on October 16, 2025, with application number 2025114816028 and invention title "A Complex Workpiece Metal Powder Processing and Forming Equipment". Technical Field

[0002] This invention belongs to the field of metal powder subtractive forming, specifically a device for processing and forming complex workpieces with metal powder. Background Technology

[0003] Metal powder die casting, more accurately known as metal injection molding, is a form of subtractive manufacturing. Metal powder can be die-cast to form metal parts with specific shapes and properties. The process involves selecting suitable metal powder, accurately measuring the mixed powder, and injecting it into a mold. Using die-casting equipment, pressure is gradually increased at a constant rate to compact the powder, forming a "green blank." The "green blank" is then heated to a temperature below its melting point for sintering, causing particle diffusion, neck growth, and metallurgical bonding, thereby obtaining parts with the desired properties.

[0004] During the die-casting stage, it is necessary to ensure that the injected metal powder is accurately measured, and at the same time, it is also necessary to ensure that the powder is evenly filled in the mold, so as to ensure that the metal powder is evenly stressed during the subsequent compaction process.

[0005] Traditional metal powder forming equipment has relatively simple functions. Generally, after the powder is injected into the forming tank, metal die casting is used directly to form the metal powder. However, due to the rapid filling of metal powder, there are gaps of varying sizes in the accumulated powder. Direct die casting can easily lead to obvious defects such as unevenness, ripples, or steps on the surface of the final product, affecting the appearance quality of the product and making it unable to meet the application scenarios with high surface precision requirements.

[0006] Therefore, the present invention provides a device for processing and forming complex workpiece metal powder. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0008] The technical solution adopted by this invention to solve its technical problem is as follows: A complex workpiece metal powder processing and forming device according to this invention includes a forming base. The top surface of the forming base has an installation groove for fixing a die-casting template. A die-casting platform is arranged above the die-casting template. A vertically arranged hydraulic rod is fixedly connected inside the die-casting platform. A die-casting block is installed at the bottom of the hydraulic rod. A forming groove is formed on the top surface of the die-casting template. An adjusting plate capable of lifting and lowering is slidably connected inside the forming groove. Multiple vibrators are installed inside the forming base. A filling cover capable of translation is slidably connected to the top surface of the forming base. The filling cover is used to inject powder into the forming groove. The top surface of the die-casting platform... An air pump is fixedly connected to the rear end, and the output end of the air pump is connected to the bottom surface of the die-casting block. This configuration ensures that the metal powder is spread evenly and without gaps in the forming tank before die casting, guaranteeing the high strength, high hardness, no deformation, and no cracks in the finished product after die casting. The entire process is smooth and fast, with the sinking of the adjusting plate, the vibration of the vibrator, and the sinking of the die-casting block all occurring simultaneously. When the die-casting block arrives at the forming tank, the sinking of the adjusting plate and the vibration of the vibrator are just completed. Upon arrival, air pressure extrusion is performed instantly, and the die-casting block does not stop during the process. The air pressure extrusion and leveling can be completed in a very short time. The time to complete all processes is no slower than that of traditional die casting equipment.

[0009] Preferably, a drive seat is fixedly connected to the rear end of the forming seat, and a recycling groove for recycling the filling hood is opened at the front end of the drive seat. A supply pipe of elastic material is fixedly connected to the top of the filling hood, and the end of the supply pipe is fixedly connected to the top of the drive seat. The horizontal movement of the filling hood can be controlled in the recycling groove of the drive seat by an electric drive rail or a cylinder telescopic rod, etc. The end of the supply pipe is fixed on the drive seat for stable connection with external feeding equipment. The elastic supply pipe can adapt to the horizontal movement process of the filling hood.

[0010] Preferably, sliding columns are fixedly connected to both sides of the top surface of the molding base near the mounting groove. The sliding columns are fixedly connected to the die-casting table, and a stabilizing plate is slidably engaged between the two sliding columns. The hydraulic rod is fixedly connected to the die-casting block through the stabilizing plate, and the air pump is connected to the die-casting block through the stabilizing plate. The cooperation between the sliding columns and the stabilizing plate ensures the stable up-and-down movement of the die-casting block. At the same time, the die-casting block is directly connected to and communicates with the stabilizing plate, which facilitates the communication process between the air pump and different die-casting blocks.

[0011] Preferably, the output end of the air pump is fixedly connected to a metal pipe, which is connected to two transmission pipes through a double-pass structure. The transmission pipes are made of elastic material. Connecting valves are fixedly connected to both sides of the front end of the stabilizing plate. The connecting valves are connected to the transmission pipes. The instantaneous air pressure input by the air pump is transmitted to the bottom of the adjusting plate through the metal pipe and the transmission pipes, and through the connecting valves and the stabilizing plate, and finally acts on the metal powder. The elastic transmission pipe is designed to adapt to the lifting and lowering process of the stabilizing plate.

[0012] Preferably, a transmission cover is fixedly connected to the top of the die-casting block, and the transmission cover is connected to a stabilizing plate. Multiple airflow holes communicating with the bottom are opened on the top surface of the die-casting block. The top of the airflow holes is located in the transmission cover, and a one-way cover is rotatably connected to the bottom of the airflow holes. Air pressure passes through the transmission cover and then through the multiple airflow holes into the forming tank to flatten the metal powder. At the same time, the one-way cover can only be opened outward and at a low angle. The one-way cover will only open during the air pressure output process. The one-way cover is a magnet and can be attracted to the die-casting block. When the air pressure stops, the one-way cover closes quickly. The contact surface between the one-way cover and the die-casting block is large, which can effectively compress the metal powder and prevent deformation and other problems.

[0013] Preferably, a flat support frame is fixed to the bottom of the die-casting table. The support frame partially blocks the bottom of the adjusting plate. The die-casting template is fixed to the forming seat by multiple fixing bolts. The forming seat has multiple electric telescopic rods that connect with the adjusting plate. The support frame supports the bottom surface of the die-casting table to support a certain workpiece. The shape of the support frame is adjusted according to the different shapes of the adjusting plate and forming groove in each die-casting template. It can support the adjusting plate, so that the support frame can stably support the pressure generated by die-casting during the die-casting process. At the same time, it can connect the electric telescopic rods to the bottom of the adjusting plate to control the lifting and lowering process of the adjusting plate. During the installation process, the die-casting template is first placed into the installation groove and then fixed with fixing bolts. Then, the top of the electric telescopic rod is controlled to lift upward, and the bottom of the adjusting plate is connected to the top of the electric telescopic rod. Then, the adjusting plate is lowered into the forming groove to complete the installation process. A support column can be installed on the top of the support frame to adapt to the shape of the adjusting plate and the finished product.

[0014] Preferably, the molding base is equipped with multiple horizontally arranged electric slide rails. Each electric slide rail has two moving ends, which are respectively connected to different electric telescopic rods. Since the shape of the adjustment plate of each die-casting template is different, by setting multiple electric telescopic rods and cooperating with the electric slide rails that control their movement, the required number of electric telescopic rods can be selected and fixed to the adjustment plate when fixing the adjustment plate, thereby adapting to the installation of various die-casting templates.

[0015] Preferably, a servo motor for driving the electric telescopic rod to rotate is fixedly connected to the bottom of the electric telescopic rod. The servo motor is slidably engaged in the electric slide rail and fixedly connected to the moving end of the electric slide rail. By controlling the rotation of the electric telescopic rod through the servo motor, the top angle of the electric telescopic rod can be adjusted. This combination with the adjustment plate allows for more states, thereby adapting to the installation of various die-casting templates.

[0016] Preferably, two electric top plates are fixedly connected to the top surface of the electric slide rail near the middle position. The electric top plates are flat and elongated, and can be pushed upwards. Multiple protrusions are fixedly connected to the top surface of the electric top plates. When the multiple electric telescopic rods are adjusted into position, the electric top plates are activated to push upwards. The bottom of the electric telescopic rods is slidably engaged in the electric slide rail. After pushing upwards, the electric telescopic rods are fixed in position due to friction, thus maintaining their stability when the adjustment plate is raised or lowered subsequently.

[0017] Preferably, the top of the electric telescopic rod is fixedly connected with a buckle, and the bottom of the adjustment plate is provided with multiple insertion holes that are adapted to the buckle. The top of the electric telescopic rod is fixed to the adjustment plate by the buckle and the insertion holes. Other fixing methods can also be used.

[0018] The beneficial effects of this invention are as follows: 1. The complex workpiece metal powder processing and forming device of the present invention uses a die casting method that sequentially performs vibration, air pressure and extrusion die casting. This method ensures that the metal powder is spread evenly and without gaps in the forming tank before die casting, guaranteeing the high strength, high hardness, no deformation and no cracks of the finished product after die casting. The overall process is smooth and fast. The sinking of the adjustment plate, the vibration of the vibrator and the sinking of the die casting block are all carried out simultaneously. When the die casting block arrives at the forming tank, the sinking of the adjustment plate and the vibration of the vibrator are just completed. After arrival, the air pressure extrusion is carried out instantly, and the die casting block does not stop during the process. The air pressure extrusion and leveling can be completed in a very short time. The time to complete all processes is no slower than that of traditional die casting equipment.

[0019] 2. The complex workpiece metal powder processing and forming device of the present invention, wherein the instantaneous air pressure input by the air pump is transmitted to the bottom of the adjusting plate through the metal pipe and the transmission pipe, and through the connecting valve and the stabilizing plate, and finally acts on the metal powder. In order to adapt to the lifting and lowering process of the stabilizing plate, the elastic transmission pipe transmits air pressure through the transmission cover, and then through multiple airflow holes into the forming groove, thereby performing the metal powder flattening work. At the same time, the one-way cover can only be opened outward and can only be opened at a low angle. The one-way cover will only open during the air pressure output. The one-way cover is a magnet and can be attracted to the die-casting block. When the air pressure stops, the one-way cover closes quickly. The contact surface between the one-way cover and the die-casting block is large, which can effectively squeeze the metal powder without deformation or other problems. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 8 As shown in the embodiment of the present invention, a complex workpiece metal powder processing and forming device includes a forming base 2. The top surface of the forming base 2 is provided with an installation groove 18 for fixing a die-casting template 6. A die-casting platform 3 is provided above the die-casting template 6. A vertically arranged hydraulic rod 10 is fixedly connected inside the die-casting platform 3. A die-casting block 14 is installed at the bottom of the hydraulic rod 10. A forming groove 16 is provided on the top surface of the die-casting template 6. An adjustment plate 17 capable of lifting and lowering is slidably connected inside the forming groove 16. Multiple vibrators 19 are installed inside the forming base 2. A filling cover 7 capable of translation is slidably connected on the top surface of the forming base 2. The filling cover 7 is used to inject powder into the forming groove 16. An air pump 4 is fixedly connected to the rear end of the top surface of the die-casting platform 3. The output end of the air pump 4 is connected to the bottom surface of the die-casting block 14. Metal powder is supplied to the bottom of the filling hood 7 through the supply pipe 8. The filling hood 7 is controlled to slide forward and move above the forming groove 16. Under the action of gravity, the metal powder will fill the forming groove 16. Then the filling hood 7 slides backward to smooth the top surface of the forming groove 16. At this time, the control adjustment plate 17 is lowered to leave a certain space above the forming groove 16. During the lowering process, the vibrator 19 inside the forming seat 2 is activated. The high-frequency vibration generated by the vibrator 19 will be transmitted to the entire forming seat 2. The vibration amplitude is small and will not affect the connection of the parts, but it can make the filled metal powder fully dispersed during the lowering process, so that the cavity that was originally there can be filled. The position is filled; after the sinking is complete, the filling powder can be spread evenly and tightly at the bottom of the forming tank 16. At this time, the die-casting block 14 is slowly sinked by the hydraulic rod 10. When the die-casting block 14 just enters the forming tank 16 and seals the forming tank 16, high-pressure air is quickly injected into the forming tank 16 by the air pump 4. Since the entire forming tank 16 is in a closed state at this time, the injected air pressure will evenly squeeze the inside of the forming tank 16. At the same time, since the air pressure is injected from top to bottom, it will squeeze the metal powder downward, greatly reducing the gap between the metal powder. At the same time, since the air pressure is applied evenly from top to bottom, This design ensures that the metal powder below is evenly spread and that the top surface is absolutely flat. A gap exists above the metal powder, allowing the air pressure to effectively act on it during injection, while also providing sufficient space for the powder to adjust its shape. Then, as the die-casting block 14 presses down, the metal powder is die-cast into a single piece. Subsequently, the die-casting block 14 is raised away from the forming groove 16, while the adjusting plate 17 rises to eject the finished product. As the filling hood 7 moves forward, the finished product is ejected outwards, and the filling hood 7 continues to fill with metal powder, repeating the die-casting process. This configuration allows the metal powder to be evenly distributed before die-casting. The powder is spread evenly and seamlessly in the forming tank 16, ensuring the high strength, high hardness, no deformation, and no cracks in the finished product after subsequent die casting. The entire process is smooth and fast. The sinking of the adjusting plate 17, the vibration of the vibrator 19, and the sinking of the die casting block 14 are all carried out simultaneously. When the die casting block 14 arrives at the forming tank 16, the sinking of the adjusting plate 17 and the vibration of the vibrator 19 are just completed. After arrival, the air pressure extrusion is carried out instantly, and the die casting block 14 does not stop die casting during the process. The air pressure extrusion and leveling can be completed in a very short time. The time to complete all processes is no slower than that of traditional die casting equipment.

[0024] The rear end of the molding seat 2 is fixedly connected to the driving seat 1, and the front end of the driving seat 1 is provided with a recycling groove for recycling the filling cover 7. The top of the filling cover 7 is fixedly connected to the supply pipe 8 of elastic material, and the end of the supply pipe 8 is fixedly connected to the top of the driving seat 1. During operation, the horizontal movement of the filling hood 7 can be controlled by an electric drive rail or a cylinder telescopic rod in the recycling tank of the drive seat 1. The end of the supply pipe 8 is fixed on the drive seat 1 for stable connection with external feeding equipment. The flexible supply pipe 8 can adapt to the horizontal movement of the filling hood 7.

[0025] The top surface of the molding base 2 is fixedly connected to both sides of the mounting groove 18 with sliding columns 12. The sliding columns 12 are fixedly connected to the die casting table 3. A stabilizing plate 11 is slidably engaged between the two sliding columns 12. The hydraulic rod 10 is fixedly connected to the die casting block 14 through the stabilizing plate 11. The air pump 4 is connected to the die casting block 14 through the stabilizing plate 11. During operation, the cooperation between the sliding column 12 and the stabilizing plate 11 ensures the stable up-and-down movement of the die-casting block 14; at the same time, the die-casting block 14 is directly connected and communicates with the stabilizing plate 11, which facilitates the communication process between the air pump 4 and different die-casting blocks 14.

[0026] The output end of the air pump 4 is fixedly connected to a metal pipe, which is connected to two transmission pipes 5 through a double-pass structure. The transmission pipes 5 are made of elastic material. Connecting valves 13 are fixedly connected to both sides of the front end of the stabilizing plate 11, and the connecting valves 13 are connected to the transmission pipes 5. During operation, the instantaneous air pressure input by the air pump 4 is transmitted to the bottom of the adjustment plate 17 through the metal pipe and transmission pipe 5, and then through the connecting valve 13 and the stabilizing plate 11, and finally acts on the metal powder. The elastic transmission pipe 5 is designed to adapt to the lifting and lowering process of the stabilizing plate 11.

[0027] The top of the die-casting block 14 is fixedly connected to a transmission cover 26, which is connected to a stabilizing plate 11. The top surface of the die-casting block 14 is provided with a plurality of airflow holes 27 that are connected to the bottom. The top of the airflow holes 27 is located in the transmission cover 26, and the bottom of the airflow holes 27 is rotatably connected to a one-way cover 28. During operation, air pressure is injected into the forming tank 16 through the transmission cover 26 and then through multiple airflow holes 27 to flatten the metal powder. At the same time, the one-way cover 28 can only be opened outwards and at a low angle. The one-way cover 28 will only open during the air pressure output process. The one-way cover 28 is a magnet and can be attracted to the die-casting block 14. When the air pressure stops, the one-way cover 28 closes quickly. The contact surface between the one-way cover 28 and the die-casting block 14 is large, which can effectively compress the metal powder and prevent deformation and other problems.

[0028] The bottom of the die-casting table 3 is fixedly connected to a flat support frame 21. The support frame 21 partially blocks the bottom of the adjustment plate 17. The die-casting template 6 is fixedly connected to the forming seat 2 by multiple fixing bolts 15. Multiple electric telescopic rods 20 that are connected to the adjustment plate 17 are installed inside the forming seat 2. During operation, the support frame 21 supports the bottom surface of the die-casting table 3 to support a certain workpiece. The shape of the support frame 21 is adjusted according to the different shapes of the adjustment plate 17 and the forming groove 16 in each die-casting template 6. It can support the adjustment plate 17, so that the support frame 21 can stably support the pressure generated by die-casting during the die-casting process. At the same time, the electric telescopic rod 20 can be connected to the bottom of the adjustment plate 17 to control the lifting and lowering process of the adjustment plate 17. During the installation process, the die-casting template 6 is first placed into the installation groove 18 and then fixed with the fixing bolts 15. Then, the top of the electric telescopic rod 20 is controlled to lift upward, and the bottom of the adjustment plate 17 is connected to the top of the electric telescopic rod 20. Then, the adjustment plate 17 is lowered into the forming groove 16 to complete the installation process. The top of the support frame 21 can be equipped with a column to adapt to the shape of the adjustment plate 17 and the finished product.

[0029] The molding base 2 is equipped with a plurality of horizontally arranged electric slide rails 22. Each electric slide rail 22 has two moving ends, and the two moving ends are respectively connected to different electric telescopic rods 20. During operation, since the adjustment plate 17 of each die-casting template 6 has a different shape, by setting multiple electric telescopic rods 20 and cooperating with electric slide rails 22 to control their movement, the required number of electric telescopic rods 20 can be selected and fixed to the adjustment plate 17 when fixing the adjustment plate 17, so as to adapt to the installation of various die-casting templates 6.

[0030] The bottom of the electric telescopic rod 20 is fixedly connected to a servo motor 25 for driving the electric telescopic rod 20 to rotate. The servo motor 25 is slidably engaged in the electric slide rail 22 and fixedly connected to the moving end of the electric slide rail 22. During operation, the electric telescopic rod 20 is rotated by the servo motor 25, which can adjust the top angle of the electric telescopic rod 20. This, combined with the adjustment plate 17, allows for more states, thus adapting to the installation of various die-casting templates 6.

[0031] Two electric top plates 24 are fixedly connected to the top surface of the electric slide rail 22 near the middle position. The electric top plates 24 are flat and long strips. The electric top plates 24 can be pushed upward. Multiple protrusions are fixedly connected to the top surface of the electric top plates 24. During operation, once the multiple electric telescopic rods 20 are adjusted to their positions, the electric top plate 24 is activated to push upwards. The bottom of the electric telescopic rods 20 is slidably engaged in the electric slide rail 22. After being pushed upwards, the electric telescopic rods 20 are fixed in that position due to friction, thus maintaining their stability when the adjustment plate 17 is raised or lowered subsequently.

[0032] The top of the electric telescopic rod 20 is fixed with a buckle, and the bottom of the adjustment plate 17 is provided with multiple insertion holes that are compatible with the buckle. During operation, the top of the electric telescopic rod 20 is fixed to the adjustment plate 17 by means of the buckle and the socket, or other fixing methods can be used.

[0033] During operation, metal powder is supplied to the bottom of the filling hood 7 through the supply pipe 8. The filling hood 7 is controlled to slide forward and move above the forming groove 16. Under the action of gravity, the metal powder will fill the forming groove 16. Then, the filling hood 7 slides backward to smooth the top surface of the forming groove 16. At this time, the control adjustment plate 17 is lowered to leave a certain space above the forming groove 16. During the lowering process, the vibrator 19 inside the forming seat 2 is activated. The high-frequency vibration generated by the vibrator 19 is transmitted to the entire forming seat 2. The vibration amplitude is small and will not affect the connection of the parts, but it can fully disperse the filled metal powder during the lowering process, so that the original metal powder is not affected. The cavity is filled; after sinking, the filling powder is spread evenly and tightly at the bottom of the molding tank 16. At this time, the die-casting block 14 is slowly sinking under the control of the hydraulic rod 10. When the die-casting block 14 just enters the molding tank 16 and seals the molding tank 16, high-pressure air is quickly injected into the molding tank 16 by the air pump 4. Since the entire molding tank 16 is in a closed state at this time, the injected air pressure will evenly squeeze the inside of the molding tank 16. At the same time, since the air pressure is injected from top to bottom, it will squeeze the metal powder downwards, greatly reducing the gap between the metal powder. At the same time, since the air pressure is applied evenly from top to bottom... The pressure ensures that the metal powder below is evenly spread and that the top surface is absolutely flat. At this point, gaps exist above the metal powder, allowing the air pressure injection to effectively act on the metal powder, and providing sufficient space for the metal powder to adjust its shape. Then, as the die-casting block 14 presses down, the metal powder is die-cast into a single piece. Subsequently, the die-casting block 14 is controlled to rise away from the forming groove 16, while the adjusting plate 17 rises to eject the finished product. As the filling hood 7 moves forward, the finished product is ejected outwards, and the filling hood 7 continues to fill with metal powder, repeating the die-casting process. Through this setup, the metal powder is allowed to be evenly spread before die-casting. The powder is spread evenly and seamlessly in the forming tank 16, ensuring the high strength, high hardness, no deformation, and no cracks in the finished product after subsequent die casting. The entire process is smooth and fast. The sinking of the adjusting plate 17, the vibration of the vibrator 19, and the sinking of the die casting block 14 are all carried out simultaneously. When the die casting block 14 arrives at the forming tank 16, the sinking of the adjusting plate 17 and the vibration of the vibrator 19 are just completed. After arrival, the air pressure extrusion is carried out instantly, and the die casting block 14 does not stop die casting during the process. The air pressure extrusion and leveling can be completed in a very short time. The time to complete all processes is no slower than that of traditional die casting equipment.

[0034] The horizontal movement of the filling hood 7 can be controlled by an electric drive rail or a cylinder telescopic rod in the recycling tank of the drive seat 1. The end of the supply pipe 8 is fixed on the drive seat 1 for stable connection with external feeding equipment. The flexible supply pipe 8 can adapt to the horizontal movement of the filling hood 7.

[0035] The cooperation between the sliding column 12 and the stabilizing plate 11 ensures the stable up-and-down movement of the die-casting block 14; at the same time, the die-casting block 14 is directly connected and communicates with the stabilizing plate 11, which facilitates the communication process between the air pump 4 and different die-casting blocks 14.

[0036] The instantaneous air pressure input by the air pump 4 is transmitted to the bottom of the adjustment plate 17 through the metal pipe and transmission pipe 5, and then through the connecting valve 13 and the stabilizing plate 11, and finally acts on the metal powder. The elastic transmission pipe 5 is designed to adapt to the lifting and lowering process of the stabilizing plate 11.

[0037] Air pressure is injected into the forming tank 16 through the transmission cover 26 and then through multiple airflow holes 27 to flatten the metal powder. At the same time, the one-way cover 28 can only be opened outwards and at a low angle. The one-way cover 28 will only open during the air pressure output process. The one-way cover 28 is a magnet and can be attracted to the die-casting block 14. When the air pressure stops, the one-way cover 28 closes quickly. The contact surface between the one-way cover 28 and the die-casting block 14 is large, which can effectively squeeze the metal powder without deformation or other problems.

[0038] The support frame 21 supports the bottom surface of the die-casting table 3 to support a certain workpiece. The shape of the support frame 21 is adjusted according to the different shapes of the adjustment plate 17 and the forming groove 16 in each die-casting template 6. It can support the adjustment plate 17, so that the support frame 21 can stably support the pressure generated by die-casting during the die-casting process. At the same time, the electric telescopic rod 20 can be connected to the bottom of the adjustment plate 17 to control the lifting and lowering process of the adjustment plate 17. During the installation process, the die-casting template 6 is first placed into the installation groove 18 and then fixed with the fixing bolts 15. Then, the top of the electric telescopic rod 20 is controlled to lift upward, and the bottom of the adjustment plate 17 is connected to the top of the electric telescopic rod 20. Then, the adjustment plate 17 is lowered into the forming groove 16 to complete the installation process. The top of the support frame 21 can be equipped with a column to adapt to the shape of the adjustment plate 17 and the finished product.

[0039] Since the adjustment plate 17 of each die-casting template 6 has a different shape, by setting multiple electric telescopic rods 20 and cooperating with electric slide rails 22 to control their movement, the required number of electric telescopic rods 20 can be selected and fixed to the adjustment plate 17 when fixing the adjustment plate 17, so as to adapt to the installation of various die-casting templates 6.

[0040] The electric telescopic rod 20 can be rotated by the servo motor 25, and the top angle of the electric telescopic rod 20 can be adjusted. This, combined with the adjustment plate 17, allows for more states, thus adapting to the installation of various die-casting templates 6.

[0041] Once the multiple electric telescopic rods 20 are adjusted into position, the electric top plate 24 is activated to push upwards. The bottom of the electric telescopic rods 20 is slidably engaged in the electric slide rail 22. After being pushed upwards, the electric telescopic rods 20 will be fixed in this position due to friction, thus maintaining their stability when the adjustment plate 17 is raised or lowered in the subsequent process.
