[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The utility model provides a casting vacuum drying tank, as Figure 1 , Figure 3 , Figure 4 and Figure 5 shown. The vacuum drying tank includes a vacuum tank 1, a support plate 2 fixedly installed on the vacuum tank 1, a motor 3 fixedly installed on the support plate 2, a rotating rod 4 fixedly installed on the output end of the motor 3, and a feeding mechanism arranged inside the vacuum tank 1;

[0024] The feeding mechanism includes two gears 5 fixedly installed on the rotating rod 4, a rack 6 rotatably connected to the gear 5, a gear 18 rotatably installed inside the rack 6, a limiting rod 19 rotatably installed inside the gear 18, a plurality of limiting blocks 7 fixedly installed on the rack 6, a fixed shaft 8 fixedly installed on the limiting block 7, and a plurality of hangers 9 movably installed on the fixed shaft 8.

[0025] During the casting production process, by turning on the switch of the motor 3, the output end of the motor 3 starts to rotate. The rotation of the output end of the motor 3 drives the rotating rod 4 to rotate. The rotation of the rotating rod 4 drives the gear 5 to rotate. The rotation of the gear 5 drives the engaged rack 6 to rotate. The rotation of the rack 6 drives the engaged gear 18 to rotate. When the limiting block 7 rotates to the feeding port, the castings made by the casting mold are hung on the hanger 9 slidably connected to the fixed shaft 8. Through the rotation of the rack 6, the hung castings will be rotated away, and the next hanger 9 without hung castings will rotate to the position of the feeding port. Then, the hanging operation is repeated until all the hangers 9 are full of castings. The castings will rotate along the rack 6. The vacuum tank 1 will be closed, and the air inside the vacuum tank 1 will be exhausted until a vacuum state is formed. In the closed environment of the vacuum tank 1, the temperature inside the vacuum tank 1 rises to 50 degrees, and the castings enter the drying stage. The vacuum environment accelerates the evaporation of moisture, ensuring the stability and durability of the casting quality. After drying, through the feeding port, the castings on each hanger 9 are taken out one by one, ready for subsequent processing or storage, and preparing for the next production cycle.

[0026] Furthermore, in order to ensure the stable state of the vacuum tank 1 during operation, as Figure 1 , Figure 2 and Figure 4 shown, the limiting block 7 is fixedly connected between the corresponding limiting blocks 7 on the two racks 6. The limiting blocks 7 are distributed in an annular array on the rack 6, and the hangers 9 are distributed in a linear array on the fixed shaft 8.

[0027] The rack 6 is engaged with the gear 5. A gasket 10 is fixedly installed at the bottom of the vacuum tank 1. A plurality of support legs 11 are fixedly installed at the bottom of the gasket 10. A bottom rod 12 is fixedly installed at the bottom of the plurality of support legs 11.

[0028] During the casting production process, the vacuum tank 1 is fixed by fixing the bottom rod 12 to a suitable ground, and by using the gasket 10 fixedly installed at the bottom of the vacuum tank 1 and the support leg 11 fixedly installed at the bottom of the gasket 10 to resist vibration and impact that may be generated during the production process. The gasket 10 avoids direct contact between the support leg 11 and the vacuum tank 1, thereby reducing the risk of wear due to friction. Furthermore, by fixing the bottom rod 12 at the bottom of the support leg 11, these support legs 11 bear the weight of the entire vacuum tank 1 and the casting inside it. These support legs 11 are tightly connected to the ground with the help of the bottom rod 12, forming a stable support network, thereby ensuring the stability of the vacuum tank 1 during operation.

[0029] In order to strengthen the stability between the support rod 13 and the bottom rod 12, Figure 1 , Figure 2 and Figure 4 As shown, the support legs 11 are distributed in a circular array on the bottom rod 12 , a support rod 13 is fixedly mounted on the top of the bottom rod 12 , and one end of the support rod 13 away from the bottom rod 12 is fixedly mounted on the support legs 11 .

[0030] Through the function of the support rod 13, the addition of the support rod 13 not only enhances the overall strength of the support structure, but also, through its unique layout, forms a stable triangular structure between the support leg 11, the base rod 12 and the support rod 13, that is, the triangular structure can disperse and balance the force when subjected to force, thereby effectively resisting deformation or damage caused by external factors.

[0031] It should be noted that, in order to facilitate the movement of the vacuum tank 1, Figure 1 , Figure 2 and Figure 4 As shown, a buckle ring 14 is rotatably mounted on the vacuum tank 1, a feeding door 15 is movably mounted inside the buckle ring 14, a stopper 16 is fixedly mounted on the top of the vacuum tank 1, and a pull ring 17 is fixedly mounted on the bottom of the vacuum tank 1.

[0032] The second gear 18 is meshed with the rack 6 , and one end of the limiting rod 19 away from the second gear 18 is fixedly connected to the inner wall of the vacuum tank 1 .

[0033] Through the stopper 16 fixedly installed on the top of the vacuum tank 1, during the operation of the vacuum tank 1, the top of the vacuum tank 1 is protected. The robot rotates the buckle 14 to open the feeding door 15, and then hangs the casting on the hanger 9 inside the vacuum tank 1. After hanging the casting, the robot rotates the buckle 14 in the reverse direction to close the feeding door 15, and then dries the casting hanging on the hanger 9. When it is necessary to take out the dried casting, the robot rotates the buckle 14 to open the feeding door 15, and then takes out the dried casting, preparing to dry the next batch of castings. When it is necessary to move the vacuum tank 1, some hard lifting rollers are inserted into the pull ring 17, and the vacuum tank 1 is lifted by lifting the lifting rollers, so as to move to the position where it needs to be moved.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
