Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0046] like Figures 1 to 10 As shown, its structural relationship is as follows: it includes a main body mechanism 1, a crucible furnace component trolley running mechanism 2, a crucible furnace component trolley lifting mechanism 3, a mold component trolley running mechanism 4 and a mold component pressing plate mechanism 5;

[0047] The main structure 1 and the crucible furnace component trolley running mechanism 2 are both installed in a preset foundation.

[0052] The staff places the crucible furnace on the crucible furnace plate 211, adjusts the adjustable limit block 212 of the crucible furnace component so that the adjustable limit block 212 of the crucible furnace component limits the crucible furnace to a suitable position, and then starts the crucible furnace component trolley motor 213. The crucible furnace component trolley motor 213 rotates, driving the transmission structure 214 at the output end to rotate together, and the transmission structure 214 drives the transmission shaft 215 to rotate. The crucible furnace component trolley flat wheel 216 and the crucible furnace component trolley groove wheel 217 installed on the transmission shaft 215 rotate together, so that the crucible furnace component trolley 21 moves to a specified position along the crucible furnace component trolley track 23 toward the main structure 1, and then turns off the crucible furnace component trolley motor 213.

Then, the crucible furnace component table positioning pin 36 installed on the lifting panel 35 is inserted into the crucible furnace component table positioning hole 218, and then the lifting panel 35 pushes the crucible furnace table 211 to lift the crucible furnace to a suitable height. The height allows the lifting pipe above the crucible furnace to extend into the table casting station hole 14. The staff turns off the hydraulic motor 34. This setting allows the crucible furnace to rise quickly to the specified height, which is conducive to ensuring production efficiency.

[0057] Preferably, the mold component trolley operating mechanism 4 includes a mold component trolley conveying frame 41, a mold component trolley track 42, a mold component trolley driving rack 43, a mold component trolley 44 and a mold component trolley lifting structure 45;

[0058] The mold component trolley track 42 is installed on the mold component trolley conveying frame 41, the mold component trolley driving rack 43 is installed on both sides of the mold component trolley conveying frame 41, the mold component trolley 44 is located on the mold component trolley track 42, and the mold component trolley lifting structure 45 is located in the middle of the mold component trolley running mechanism 4 and is installed on the work table 13;

The mold component trolley inner car pin hole 447 is opened on the mold component trolley inner car 446. The mold component trolley inner car pin hole 447 is located directly above the mold component trolley pin shaft 445. The mold component trolley inner car flat wheels 449 are installed on both sides of the mold component trolley inner car 446. The mold component trolley inner car 446 is opened in the middle of the mold component trolley casting station hole 448.

[0061] The mold component trolley lifting structure 45 includes a mold component trolley lifting structure cylinder 451, a mold component trolley lifting beam guide rod 452 and a mold component trolley lifting beam 453;

[0062] The mold part trolley lifting structure cylinder 451 is installed under the work table 13, and its output end passes through the work table 13 and is installed and connected to the mold part trolley lifting beam 453. The lower end of the mold part trolley lifting beam guide rod 452 is installed and connected to the work table 13, and the upper end is installed and connected to the mold part trolley lifting beam 453.

[0063] The staff installs the mold on the mold part trolley inner car 446, adjusts the mold position so that the injection hole below the mold is aligned with the mold part trolley casting station hole 448, starts the outer motor of the mold part trolley outer car 442, and the mold part trolley driving gear 441 at the output end of the motor rotates on the mold part trolley driving rack 43, driving the mold part trolley outer car 442 and the mold part trolley inner car 446 to move along the mold part trolley track 42 toward the main structure 1 to a suitable position, which is the position where the mold part trolley casting station hole 448 is concentric with the table casting station hole 14 below. Then, the mold part trolley is closed. The outer motor of the outer car 442 starts the mold part trolley lifting structure cylinder 451, and the mold part trolley lifting beam 453 at the output end of the mold part trolley lifting structure cylinder 451 descends, causing the mold part trolley inner car 446 above to descend together, and the mold part trolley inner car 446 descends to a suitable height along the direction of the mold part trolley pin shaft 445. This height allows the liquid rising pipe above the crucible furnace to pass through the mold part trolley casting station hole 448 and rest against the hole below the mold, and close the mold part trolley lifting structure cylinder 451. This setting allows the mold to move quickly and descend to the specified position, which is beneficial to ensuring production efficiency.

[0066] The staff starts the mold part pressure plate cylinder 54, and the output end of the mold part pressure plate cylinder 54 extends downward. The mold part pressure plate 51 at the output end of the mold part pressure plate cylinder 54 moves downward together until the mold part pressure plate 51 rests against the mold below. This setting can prevent the mold from moving during use, which is beneficial to ensuring production efficiency.

[0067] Preferably, it further comprises a pressure plate self-locking device 6 , which is installed on the mold component pressure plate support plate 17 and is used to limit the displacement of the mold component pressure plate 51 relative to the pressure plate support plate 17 .

[0068] This setting can start the self-locking device 6 after the mold part pressure plate mechanism 5 stops working, so that the mold part pressure plate 51 cannot move, effectively preventing the mold part pressure plate 51 from extending downward due to gravity factors, causing damage to the mold part pressure plate cylinder 54, which is beneficial to cost control.

[0069] Preferably, there are four platen casting station holes 14, four corresponding mold component trolley casting station holes 448, four crucible furnace component platen positioning holes 218, and four corresponding crucible furnace component platen positioning pins 36.

[0070] During use, the liquid in the crucible furnace is injected into the mold through the table casting station hole 14 and the mold component trolley casting station hole 448. The four holes are conducive to improving production efficiency. The four crucible furnace component table positioning holes 218 and the crucible furnace component table positioning pins 36 cooperate with each other to improve accuracy, so that the crucible furnace in the crucible furnace component trolley 21 can be accurately aligned with the table casting station hole 14 during the rising process of the trolley lifting panel 35, which is conducive to improving production efficiency.

[0073] Preferably, there are two crucible furnace component trolleys 21 and two mold component trolleys 44 , which are located at both ends of the crucible furnace component trolley track 23 and the mold component trolley track 42 respectively.

[0074] This arrangement allows one crucible furnace component trolley 21 and mold component trolley 44 to be equipped with a crucible furnace and mold during the casting process. The two trolleys can operate alternately, which is beneficial to ensuring production efficiency.

[0075] Preferably, the number of the optical axis guide rods 52 is three, and the number of the tooth groove guide rod 53 is one.

[0076] The specific use includes the following process:

[0077] In the first step, the staff places the crucible furnace filled with magnesium alloy solution on the crucible furnace plate 211 on the crucible furnace component trolley 21, and adjusts the adjustable limit block 212 of the crucible furnace component so that the adjustable limit block 212 of the crucible furnace component limits the crucible furnace to a suitable position. Then, the staff installs the mold on the inner car 446 of the mold component trolley, and adjusts the position of the mold so that the injection hole below the mold is aligned with the casting station hole 448 of the mold component trolley.

[0078] In the second step, the staff starts the crucible furnace component trolley motor 213, and the crucible furnace component trolley motor 213 rotates, driving the transmission structure 214 at the output end to rotate together, and the transmission structure 214 drives the transmission shaft 215 to rotate, and the crucible furnace component trolley flat wheel 216 and the crucible furnace component trolley groove wheel 217 installed on the transmission shaft 215 rotate together, so that the crucible furnace component trolley 21 moves along the crucible furnace component trolley track 23 toward the main structure 1 to the specified position, which is the position where the crucible furnace rising pipe is aligned with the table casting station hole 14, and the crucible furnace component trolley motor 213 is turned off.

[0079] In the third step, the staff starts the hydraulic motor 34. The hydraulic motor 34 controls the output end of the jack 32 to rise upward through the coupling 33 connected to the output end. The lifting panel 35 installed on the output end of the jack 32 also rises upward. Then, the crucible furnace component table positioning pin 36 installed on the lifting panel 35 is inserted into the crucible furnace component table positioning hole 218. The lifting panel 35 pushes the crucible furnace table 211 to lift the crucible furnace to a suitable height. The height allows the lifting pipe above the crucible furnace to extend into the table casting station hole 14, and then the hydraulic motor 34 is turned off.

[0080] In the fourth step, the staff starts the outer motor of the mold part trolley 442, and the mold part trolley driving gear 441 at the output end of the motor rotates on the mold part trolley driving rack 43, driving the mold part trolley outer car 442 and the mold part trolley inner car 446 to move along the mold part trolley track 42 toward the main structure 1 to a suitable position, which is the position where the mold part trolley casting station hole 448 is concentric with the table casting station hole 14 below, and turns off the outer motor of the mold part trolley 442.

[0081] In the fifth step, the staff starts the mold part trolley lifting structure cylinder 451, and the mold part trolley lifting beam 453 at the output end of the mold part trolley lifting structure cylinder 451 descends, causing the mold part trolley inner car 446 above to descend together. After the mold part trolley inner car 446 descends to a suitable height along the direction of the mold part trolley pin shaft 445, the height can allow the liquid rising pipe above the crucible furnace to pass through the mold part trolley casting station hole 448 and against the hole below the mold, and then the mold part trolley lifting structure cylinder 451 is closed.

[0082] In the sixth step, the staff releases the self-locking device 6 so that the self-locking device 6 no longer restricts the movement of the mold part pressure plate 51. Then, the mold part pressure plate cylinder 54 is started, and the output end of the mold part pressure plate cylinder 54 extends downward. The mold part pressure plate 51 at the output end of the mold part pressure plate cylinder 54 moves downward together until the mold part pressure plate 51 presses against the mold below, so that the mold is subjected to downward pressure.

[0083] In the seventh step, the staff operates the pressurization system of the crucible furnace component to start working, so that the magnesium alloy liquid rises along the riser tube and is injected into the mold cavity from bottom to top through the injection hole of the mold box to perform anti-gravity casting operations.

[0084] In the eighth step, after the casting operation is completed, the staff starts the mold part pressure plate oil cylinder 54, the output end of the mold part pressure plate oil cylinder 54 extends upward, and the mold part pressure plate 51 at the output end of the mold part pressure plate oil cylinder 54 moves upward together so that the mold part pressure plate 51 no longer presses against the mold below.

[0085] In the ninth step, the staff starts the mold part trolley lifting structure cylinder 451, and the mold part trolley lifting beam 453 at the output end of the mold part trolley lifting structure cylinder 451 rises, causing the mold part trolley inner car 446 above to rise together.

[0087] In the eleventh step, the staff starts the hydraulic motor 34. The hydraulic motor 34 controls the output end of the jack 32 to descend through the coupling 33 connected to the output end. The lifting panel 35 installed on the output end of the jack 32 also descends. Subsequently, the crucible furnace component table positioning pin 36 installed on the lifting panel 35 is disengaged from the crucible furnace component table positioning hole 218. The lifting panel 35 drives the crucible furnace table 211 to descend the crucible furnace to the initial position, and then the hydraulic motor 34 is turned off.

[0088] In the twelfth step, the staff starts the crucible furnace component trolley motor 213, and the crucible furnace component trolley motor 213 rotates, driving the transmission structure 214 at the output end to rotate together, and the transmission structure 214 drives the transmission shaft 215 to rotate, and the crucible furnace component trolley flat wheel 216 and the crucible furnace component trolley groove wheel 217 installed on the transmission shaft 215 rotate together, so that the crucible furnace component trolley 21 returns to the initial position along the crucible furnace component trolley track 23, and then turns off the crucible furnace component trolley motor 213. Subsequently, the staff removes the crucible furnace component on the crucible furnace component trolley 21.

[0089] In the thirteenth step, the staff asks the second crucible furnace component trolley 21 and the mold component trolley 44 to repeat the first to twelfth steps. After completing the casting operation, the staff asks the first crucible furnace component trolley 21 and the mold component trolley 44 to repeat the first to twelfth steps. The two crucible furnace component trolleys 21 and the mold component trolley 44 work alternately until the required workload is completed.
