Description

[0002] Automotive metal casting involves pouring molten metal from a smelting drum into a casting cavity tailored to the part's shape. After cooling and solidification, the resulting metal part blank possesses a defined shape, size, and performance.

[0040] It should be noted here that: the threaded rod 1002 is driven to rotate by driving the motor 1004. During the rotation of the threaded rod 1002, the sealing plate 801 is moved after being subjected to force through the mutual engagement transmission between the threaded rod 1002 and the threaded tube 1003 and the sliding guiding effect of the second sleeve 1101 and the second slide rod 1102.

[0043] Preferably, a vibration plate 13 is provided between the mounting plate 3 and the rectangular plate 4 for contacting the liquid storage cylinder 803 during liquid supply and delivery.

[0044] It should be noted that when the liquid storage cylinder 803 is driven 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 toward the second fixed plate 1502. During the movement of the vibration plate 13, the vibration plate 13 and the liquid storage cylinder 803 are vibrated through the transmission assembly. The vibration effect facilitates the complete and efficient conveying operation of the liquid metal filled in the auxiliary liquid storage cylinder 803.

[0045] It is worth noting here that the protrusion 1404 is made of polytetrafluoroethylene, which has a certain elasticity and is resistant to high temperatures. It ensures stable transmission and avoids getting stuck when it contacts the vibration plate 13 through its own elastic effect.

[0047] It should be noted here that: 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 is against the vibration plate 13 and pushes the vibration plate 13 to move toward the second fixed plate 1502. In the process of the movement of the vibration plate 13, the mutual engagement transmission between the second gear 1501 and the second rack 1503 drives the rotating shaft 1402 to rotate.

[0048] Preferably, the telescopic assembly includes two sets of third sleeves 1601 fixed to one side of the vibration plate 13, a third sliding rod 1602 is slidably connected to the third sleeve 1601, one end of the third sliding rod 1602 is fixed to the second fixing plate 1502, and a second spring 1603 is sleeved on the outer side of the third sleeve 1601;

[0049] It should be noted that the third sleeve 1601 and the third slide bar 1602 facilitate the stable and telescopic connection of the auxiliary vibration plate 13, and the second spring 1603 facilitates the reset movement of the vibration plate 13 after the telescopic movement.

[0050] In this solution: A molten metal conveying device for casting automobile metal parts includes 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 placed under the connecting pipe 2 and communicates with the flow hole 802. During the movement of the blocking plate 801, the transmission plate 1203 is driven to move synchronously through the connection transmission action of the connecting frame 1204. 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 mutual meshing transmission between the mounting shaft 604 and the first gear 1201 drives the mounting shaft 604 to rotate. During the rotation of the mounting shaft 604, the ball valve 602 is driven to rotate inside the ball groove 601. Through the rotation of the ball valve 602, the circular hole 603 on the ball valve 602 is connected to the smelting cylinder 1 and the flow hole 802 respectively. At this time, the liquid metal melted in the smelting cylinder 1 is transported to the interior of the liquid storage cylinder 803 through the connecting pipe 2. Because the rectangular plate 4 abuts against the bottom of the liquid storage cylinder 803, the bottom of the liquid storage cylinder 803 is blocked and the liquid metal in the liquid storage cylinder 803 is transported, so that the interior of the liquid storage cylinder 803 and the flow hole 802 are filled with liquid metal.

[0052] After the liquid storage cylinder 803 is filled, the blocking plate 801 and the liquid storage cylinder 803 are driven to move by the cooperation of the moving assembly and the guide assembly, 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 by the rotating assembly, so that the round hole 603 is not connected to the inside of the smelting cylinder 1. When the liquid is discharged, the liquid discharge operation is no longer continued, which is convenient for effectively controlling the liquid discharge from the inside of the smelting cylinder 1. 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 is 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 engaged with each other to drive the rotating shaft 1402 to rotate. During the rotation of the rotating shaft 1402, the groups of protrusions 1404 on the driving disk 1403 are driven to counteract the vibration plate 13 in turn. Through the counteraction of the groups of protrusions 1404, the vibration plate 13 and the liquid storage cylinder 803 vibrate. Through the vibration effect, the complete and efficient transportation operation of the liquid metal filled in the auxiliary liquid storage cylinder 803 is facilitated.
