[0041] The bottom of the die-casting table 3 is fixed with the flat support frame 21, the support frame 21 partially blocks the bottom of the adjusting plate 17, the die-casting template 6 is fixed with the forming base 2 through a plurality of fixing bolts 15, and a plurality of electric telescopic rods 20 are arranged in the forming base 2 and are in abutment with the adjusting plate 17.

[0042] When working, the bottom surface of the die casting table 3 is supported by the support frame 21 to a certain workpiece, and the shape of the support frame 21 is adjusted according to the different shapes of the adjusting plate 17 and the forming groove 16 in each die casting template 6. The support frame 21 can support the adjusting plate 17, so that the support frame 21 can stably support the pressure generated during die casting, and the electric telescopic rod 20 can be connected with the bottom of the adjusting plate 17 to control the lifting process of the adjusting plate 17. During installation, first put the die casting template 6 into the installation groove 18, then fix it with the fixing bolt 15, then control the electric telescopic rod 20 to top up, connect the bottom of the adjusting plate 17 with the top of the electric telescopic rod 20, and then let the adjusting plate 17 sink into the forming groove 16, complete the installation process; The top of the support frame 21 can be installed with a support column to adapt to the shape of the adjusting plate 17 and the finished product.

[0043] A plurality of horizontally arranged electric sliding rails 22 are installed inside the forming seat 2, and the electric sliding rails 22 have two moving ends, which are respectively connected with different electric telescopic rods 20.

[0044] When working, since the shape of the adjusting plate 17 of each die casting template 6 is different, by setting a plurality of electric telescopic rods 20 and cooperating with the electric sliding rails 22 for controlling their movement, the required number of electric telescopic rods 20 can be selected and fixed with the adjusting plate 17 when fixing the adjusting plate 17, so as to adapt to the installation of various die casting templates 6.

[0045] The bottom of the electric telescopic rod 20 is fixedly connected with a servo motor 25 for driving the electric telescopic rod 20 to rotate, the servo motor 25 is slidingly connected in the electric sliding rail 22, and the moving end of the electric sliding rail 22 is fixedly connected with the servo motor 25.

[0046] When working, the servo motor 25 controls the electric telescopic rod 20 to rotate, which can adjust the angle of the top of the electric telescopic rod 20, so that in combination with the adjusting plate 17, more states can be obtained to adapt to the installation of various die casting templates 6.

[0047] Two electric jacks 24 are fixedly connected to the top surface of the electric sliding rail 22 at the middle position, the electric jacks 24 are arranged in a flat strip shape, the electric jacks 24 can be jacked up, and a plurality of protrusions are fixedly connected to the top surface of the electric jacks 24.

[0048] When working, after the plurality of electric telescopic rods 20 are adjusted in place, the electric jacks 24 are started to be jacked up, the bottom of the electric telescopic rod 20 is slidingly connected in the electric sliding rail 22, and after jacking up, the electric telescopic rod 20 is fixed at this position due to the action of friction, so that the stability of the electric telescopic rod 20 is maintained when the adjusting plate 17 is lifted subsequently.

[0050] In operation, the top of the electric telescopic rod 20 is fixed with the adjusting plate 17 through the lock buckle and the insertion hole, and other fixing modes can also be adopted.

[0051] In operation, the metal powder is supplied to the bottom of the filling cover 7 through the supply pipe 8, the filling cover 7 is controlled to slide forward and move above the forming groove 16, and the metal powder fills the forming groove 16 under the action of gravity. Then the filling cover 7 slides backward to flatten the top surface of the forming groove 16. At this time, the adjusting plate 17 is controlled to sink, leaving a certain space above the forming groove 16. In the sinking process, the vibrator 19 inside the forming seat 2 is started. The high-frequency vibration generated by the vibrator 19 is transmitted to the entire forming seat 2. The vibration amplitude is small and does not affect the connection of the parts, but can fully shake the filled metal powder during the sinking process, so that the positions with original cavities are filled. After the sinking is completed, the filled powder is evenly and tightly laid on the bottom of the forming groove 16. At this time, the die-casting block 14 is controlled to slowly sink by the hydraulic rod 10. When the die-casting block 14 just enters the forming groove 16 and blocks the forming groove 16, high-pressure air is rapidly injected into the forming groove 16 through the air pump 4. Since the entire forming groove 16 is in a closed state at this time, the inward injection pressure uniformly extrudes the inside of the forming groove 16. At the same time, since the air pressure is injected from top to bottom, it will extrude the metal powder downward, greatly reducing the gap between the metal powder. At the same time, due to the uniform pressure of the air pressure from top to bottom, it can ensure that the metal powder below is evenly laid, and the top surface is absolutely flat. At this time, there is a gap above the metal powder, so that the air pressure can effectively act on the metal powder when the air pressure is injected, and the metal powder also has enough space for shape adjustment. Then the metal powder is die-cast into one body with the die-casting block 14. Then the die-casting block 14 is controlled to rise and leave the forming groove 16, and the adjusting plate 17 is controlled to rise to eject the finished product. With the forward movement of the filling cover 7, the finished product is ejected outward. The filling cover 7 continues to fill the metal powder, and the above die-casting work is repeated. Through this arrangement, the metal powder is evenly laid in the forming groove 16 without gap before die-casting, which ensures the high strength, high hardness, no deformation, no crack and other qualities of the finished product after subsequent die-casting. The overall 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 synchronized. The sinking and vibration of the adjusting plate 17 are completed just before the die-casting block 14 reaches the forming groove 16. The air pressure extrusion is completed in a very short time. The time for completing all processes will not be slower than that of the traditional die-casting equipment.

[0052] The electric drive rail or the cylinder telescopic rod and other structures can be used in the recovery groove of the driving base 1 to control the horizontal movement of the filling cover 7. The end of the supply pipe 8 is fixed on the driving base 1, which is used for stable connection with the external feeding equipment. The elastic supply pipe 8 can adapt to the horizontal movement of the filling cover 7.

[0053] The cooperation of the slide column 12 and the stable plate 11 ensures the stable up-down movement of the die-casting block 14. At the same time, the die-casting block 14 is directly connected with the stable plate 11 and communicates with the stable plate 11, which facilitates the connection process of the air pump 4 and different die-casting blocks 14.

[0054] The air pressure instantaneously input by the air pump 4 is transmitted to the bottom of the adjusting plate 17 through the metal pipe and the transmission pipe 5, the connecting valve 13 and the stable plate 11, and finally acts on the metal powder. The elastic transmission pipe 5 is used to adapt to the lifting process of the stable plate 11.

[0055] The air pressure is injected into the forming groove 16 through the transmission cover 26 and then through a plurality of air flow holes 27, so as to perform the metal powder flattening work. At the same time, the one-way cover 28 can only be opened outward and can only be opened at a low angle. The one-way cover 28 will be opened only during the air pressure output process. The one-way cover 28 is a magnet and can be adsorbed on the die-casting block 14. When the air pressure stops, the one-way cover 28 quickly closes. The contact surface between the one-way cover 28 and the die-casting block 14 is large, which can effectively extrude the metal powder and will not cause deformation and other problems.

[0056] The bottom surface of the die-casting table 3 is supported by the support frame 21 to a certain workpiece. The shape of the support frame 21 is adjusted according to the different shapes of the adjusting plate 17 and the forming groove 16 in each die-casting template 6. The support frame 21 can support the adjusting plate 17 and stably support the pressure generated during the die-casting process. At the same time, the electric telescopic rod 20 can be connected with the bottom of the adjusting plate 17 to control the lifting process of the adjusting plate 17. During the installation process, the die-casting template 6 is first placed in the installation groove 18, and then the fixing bolt 15 is used for fixation. Then the top of the electric telescopic rod 20 is controlled to be lifted upward, the bottom of the adjusting plate 17 is connected with the top of the electric telescopic rod 20, and then the adjusting plate 17 is sunk into the forming groove 16 to complete the installation process. The top of the support frame 21 can be installed with a support column to adapt to the shape of the adjusting plate 17 and the finished product.

[0057] Due to the different shapes of the adjusting plate 17 of each die-casting template 6, a plurality of electric telescopic rods 20 are arranged, and the electric sliding rails 22 for controlling the movement of the electric telescopic rods 20 are arranged. When the adjusting plate 17 is fixed, the required number of electric telescopic rods 20 can be selected and fixed on the adjusting plate 17 to adapt to the installation of various die-casting templates 6.

[0058] The electric telescopic rod 20 is controlled to rotate by the servo motor 25, the top angle of the electric telescopic rod 20 is adjusted, and the combination of the adjustment plate 17 can have more states to adapt to the installation of various die plates 6.

[0059] When the electric telescopic rod 20 is adjusted to the position, the electric top plate 24 is started to be upwardly pressed, the bottom of the electric telescopic rod 20 is slidingly clamped in the electric slide rail 22, and after being upwardly pressed, the electric telescopic rod 20 is fixed in the position due to the friction, so that the stability of the electric telescopic rod 20 is maintained when the adjustment plate 17 is subsequently controlled to be lifted and lowered.
