In the process of the vibration plate 13 moving, the vibration plate 13 and the liquid storage cylinder 803 are vibrated through the first transmission assembly.

[0050] In this scheme: A molten metal conveying device for casting automobile metal parts comprises the following steps:

[0051] During the casting process of automobile metal parts, the smelting cylinder 1 is used to melt the metal into liquid. After the smelting is completed, the blocking plate 801 and the liquid storage cylinder 803 are driven to move between the mounting plate 3 and the rectangular plate 4 through the transmission action of the moving assembly and the guide assembly. Through the movement, the liquid storage cylinder 803 is located below the connecting pipe 2 and communicates with the flow hole 802. During the movement of the blocking plate 801, the connecting transmission action of the connecting frame 1204 drives the transmission plate 1203 to move synchronously. During the movement of the transmission plate 1203, the first rack 1202 is driven to move. During the movement of the first rack 1202, the first rack 1202 is driven to move. The installation shaft 604 is driven to rotate by mutual meshing transmission with the first gear 1201. During the rotation of the installation shaft 604, the ball valve 602 is driven to rotate inside the ball groove 601. Through the rotation of the ball valve 602, the round hole 603 on the ball valve 602 is communicated with the smelting cylinder 1 and the flow hole 802 respectively. At this time, the liquid metal melted inside the smelting cylinder 1 is transported to the inside of the liquid storage cylinder 803 through the connecting pipe 2. Because the rectangular plate 4 is against the bottom of the liquid storage cylinder 803, the inside of the liquid storage cylinder 803 and the flow hole 802 are filled with liquid metal through the blocking effect on the bottom of the liquid storage cylinder 803 and the conveying effect on the liquid metal inside the liquid storage cylinder 803.

[0052] After the liquid storage cylinder 803 is filled, the blocking plate 801 and the liquid storage cylinder 803 are driven to move through the cooperation of the moving component and the guide component, so that the liquid storage cylinder 803 moves to the top of the liquid outlet pipe 5. During the movement of the blocking plate 801, the bottom of the connecting pipe 2 is blocked by the blocking plate 801 to prevent the excess liquid metal in the connecting pipe 2 from flowing out. In addition, during the movement of the blocking plate 801, the ball valve 602 is driven to rotate inside the ball groove 601 through the rotating component, so that the round hole 603 is not connected to the inside of the smelting cylinder 1. When the liquid discharge operation is stopped, the liquid discharge from the smelting cylinder 1 is effectively controlled. When the liquid storage cylinder 803 moves to the top of the liquid discharge pipe 5, the liquid metal in the liquid storage cylinder 803 is transported to the inside of the casting cavity through the liquid discharge pipe 5 to assist in the casting of automobile metal parts. In the entire process of liquid metal transportation, the amount of liquid metal transported to the casting cavity is the liquid metal stored between the liquid storage cylinder 803 and the flow hole 802, forming a quantitative transportation operation of liquid metal during the casting process, avoiding excessive waste of liquid metal while ensuring the quality of casting.

[0053] In the process of driving the liquid storage cylinder 803 to move above the liquid outlet pipe 5, the outer side of the liquid storage cylinder 803 abuts against the vibration plate 13 and pushes the vibration plate 13 to move toward the second fixed plate 1502. During the movement of the vibration plate 13, the second gear 1501 and the second rack 1503 are mutually engaged to drive the rotating shaft 1402 to rotate. During the rotation of the rotating shaft 1402, each group of protrusions 1404 on the driving disk 1403 is driven to abut against the vibration plate 13 in turn. Through the abutment of each group of protrusions 1404, the vibration plate 13 and the liquid storage cylinder 803 are vibrated. Through the vibration effect, the complete and efficient conveying operation of the liquid metal filled in the auxiliary liquid storage cylinder 803 is facilitated.
