[0040] The first servo motor 3, the second servo motor 25, the electric telescopic rod 26, the electric control rod 39 and the electric adjustment rod 44 in this embodiment are all conventional devices purchased on the market and well known to those skilled in the art. In the present invention, we only use them without improving their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method can be debugged and operated according to the requirements of their instruction manuals, and will not be described in detail here.

[0041] To sum up, the working principle of the intelligent casting device for alloy heterogeneous castings of new energy vehicles is as follows: when in use, the intelligent casting device for alloy heterogeneous castings of new energy vehicles is first installed at the location where it is required to be used, and then a control power supply and a controller are installed for the first servo motor 3, the second servo motor 25, the electric telescopic rod 26, the electric control rod 39 and the electric adjustment rod 44. After that, the power-on operation control of the first servo motor 3, the second servo motor 25, the electric telescopic rod 26, the electric control rod 39 and the electric adjustment rod 44 can be realized through the controller. Under the meshing transmission action of the driving gear on the output shaft of the first servo motor 3 and the transmission gear ring outside the rotating cylinder 2, the power-on operation of the first servo motor 3 can realize the rotation of the rotating cylinder 2. Drive, the rotation of the rotating cylinder 2 realizes the synchronous rotation drive of the casting mold and the follow-up mounting assembly, and the second servo motor 25 is powered on to realize the rotation drive of the second mounting seat 24. Since a synchronous frame is provided between the first mounting seat 23 and the second mounting seat 24, the rotation of the second mounting seat 24 will drive the first mounting seat 23 to form a synchronous rotation drive, and finally realize the synchronous rotation adjustment of the first bottom mold 4 and the second bottom mold 5, so that the cast new energy vehicle alloy heterogeneous casting has faults distributed at different levels. The operation of the electric telescopic rod 26 can realize the relative sliding adjustment of the first bottom mold 4 relative to the first mounting seat 23. The movement of the first bottom mold 4 drives the movement of the bending rod 28, the movement of the first bending rod 28 drives the transmission rod 29 to move, and the movement of the transmission rod 29 drives the first The two bottom molds 5 move, thereby achieving a relative movement away from or a relative movement towards each other between the first bottom mold 4 and the second bottom mold 5, and when the first bottom mold 4 and the second bottom mold 5 move relative to each other synchronously, the two straight oblique rods 30 will also be driven to move. The movement of the two straight oblique rods 30 will form the movement of the lifting frame 32, and then the middle top mold 6 will be raised relative to the first bottom mold 4 and the second bottom mold 5. Therefore, by operating the electric telescopic rod 26 to control the first bottom mold 4 to approach the first mounting seat 23, the synchronous relative separation between the first bottom mold 4, the second bottom mold 5 and the middle top mold 6 can be achieved. Conversely, when the electric telescopic rod 26 is used to operate to control the first bottom mold 4 to move away from the first mounting seat 23, the synchronous relative separation between the first bottom mold 4, the second bottom mold 5 and the middle top mold 6 can be achieved. When the limit plate 43 blocks the stepped hole, the counterweight column 11 cannot move out of the stepped hole. When the limit plate 43 avoids the stepped hole, the counterweight column 11 can move out of the stepped hole. When the electric control lever 39 is powered on, the gate plate 37 can be pushed and moved. When the through hole on the gate plate 37 is connected with the hole at the bottom of the casting box 36, the liquid casting material in the casting box 36 will fall into the casting tube 27 through the through hole. On the contrary, when the through hole on the gate plate 37 is misaligned with the hole at the bottom of the casting box 36, the liquid casting material in the casting box 36 will not enter the casting tube 27.

[0042] Furthermore, during pouring, any one of the two split cover doors 15 is first rotated to realize the movement drive of the transmission bar frame 16 and the rotating shaft 17. Under the transmission action between the rotating shaft 17 and the circular hole groove 19, the sliding frame 13 will form a relative sliding between the two covered rails 14, so that the rotating cylinder 2 moves forward in the main frame 1. At the same time, the slope frame 22 will push the center column 21 to form a relative rise through the guide block 46, and finally the double bracket 20 will be raised in the rotating cylinder 2 to facilitate the demoulding operation of the alloy heterogeneous casting of new energy vehicles. Since the guide groove 45 is provided with a slope and a plane, when the guide block 46 moves to the plane position on the guide groove 45, the center column 21 will rise to the limit position. Thereafter, the center column 21 The height of the casting box 36 will be kept at a certain height, and the relative opening state of the two split cover doors 15 will also be maintained to facilitate the demoulding operation of the alloy heterogeneous castings of new energy vehicles. During the casting operation, the split cover doors 15 are opened, and the material holes on the gate 37 are misaligned with the holes at the bottom of the casting box 36 by controlling the operation of the electric control rod 39. The cover plate 40 is opened to add different liquid casting materials into the two casting boxes 36, and the cover plate 40 is closed first and then the split cover doors 15 are closed. Then, the electric telescopic rod 26 is started to control the first bottom mold 4, the second bottom mold 5 and the middle top mold 6 to be relatively close to each other to form a closed casting cavity. Then the first servo motor 3 is powered on to realize the rotation drive of the rotating drum 2. When the rotating drum 2 rotates into a stable state, the electric control rod 39 is used to control the rotation of the rotating drum 2. The rod 39 realizes the sliding drive of the gate 37, so that the casting material in the casting box 36 flows into the casting cavity to form casting. Under the state of centrifugal force, the casting material will first fill the two ends of the casting cavity. The centrifugal rotation state is maintained to control the two ends of the casting mold through the second servo motor 25 to form a reciprocating alternating rising and lowering posture, which can make the casting material entering the casting cavity first fill the two end surfaces of the new energy vehicle alloy heterogeneous casting, and then the electric control rod 39 is operated to realize the movement adjustment of the gate 37, so that another casting material flows into the casting cavity, and forms a casting filling on the interior of the new energy vehicle alloy heterogeneous casting that has been formed on the surface, thereby achieving the sequential casting of the inner and outer double layers of materials. During the casting operation, the limit is controlled by the electric adjustment rod 44 The plate 43 is avoided relative to the stepped hole, and the centrifugal drive of the counterweight column 11 can be realized under the action of centrifugal force. The counterweight column 11 in the centrifugal force state will form relative movement in the stepped hole, and the force transmission drive of the traction rope 42 will cause the first arc rod 7 and the second arc rod 8 to be inserted into the casting cavity relative to each other, and accompanied by the solidification and formation of the outer surface of the new energy vehicle alloy heterogeneous casting. Since the internal structural strength requirement of the new energy vehicle alloy heterogeneous casting is smaller than the external structural strength requirement, the rotation speed of the rotating drum 2 can be appropriately reduced, so the rotation speed of the counterweight column 11 will also be reduced, which makes it convenient for the first arc rod 7 and the second arc rod 8 to be demoulded relative to the new energy vehicle alloy heterogeneous casting in the casting cavity. After one type of casting material is poured,When pouring another type of casting material, the rotation of the rotating cylinder 2 should be stopped first, and the limit plate 43 should be controlled to reset the stepped hole. After that, the rotating cylinder 2 rotates again. Even if the counterweight column 11 is under centrifugal force, it will not drive the first curved rod 7 and the second curved rod 8. Since the first curved rod 7 and the second curved rod 8 will form an arc hole for the casting material during the aforementioned pouring process, the other casting material will fill the arc hole relative to the casting material during pouring, thereby improving the connection effect of the joint between the two casting materials and ensuring the integrity of the new energy vehicle alloy heterogeneous casting. After the pouring is completed, the gate plate 37 is controlled to seal the two pouring boxes 36. After the new energy vehicle alloy heterogeneous casting is cooled and solidified, the electric telescopic rod 26 is used to operate to achieve the relative separation of the first bottom mold 4, the second bottom mold 5 and the middle top mold 6, and finally the new energy vehicle alloy heterogeneous casting is demoulded after the pouring is completed.
