DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0026] like Figures 1 to 7As shown, a light alloy pneumatically controlled suspension casting device comprises a lower tank body 1, an intermediate tank body 2 and an upper tank body 3. The intermediate tank body 2 is fixedly mounted on the intermediate tank bracket 14 through a dual-axis cylinder 24. Locking rings 13 are provided at both upper and lower ends of the intermediate tank body 2. A locking push ear 27 is fixedly mounted on the outer side of the locking ring 13. The locking push ear 27 is connected to the end of the telescopic rod of the locking oil cylinder 26 through a fisheye joint. The other end of the locking oil cylinder 26 is rotatably connected to the locking upper oil cylinder base 25. The upper tank body 3 is arranged in the inner cavity of the trapezoidal movable frame 7. A transition sprocket 15 and a driving sprocket 17 are fixedly mounted on the top of the trapezoidal movable frame 7. A lower position between the transition sprocket 15 and the driving sprocket 17 is provided. The tensioning sprocket 16, the transition sprocket 15, the tensioning sprocket 16 and the driving sprocket 17 are connected through a chain 34 transmission. The center position of the driving sprocket 17 is cooperated with the side spindle 18, and the side spindle 18 is connected to the intermediate spindle 20 through a coupling 19. A reverse ratchet 22 is installed on the intermediate spindle 20, and a reverse pawl 23 is provided above the reverse ratchet 22. One end of the reverse pawl 23 is rotatably connected to the trapezoidal movable frame 7 through a rotating shaft 41, and a self-locking cylinder 40 is provided between the other end of the reverse pawl 23 and the trapezoidal movable frame 7. Ratchet seats 21 are symmetrically provided near the two end heads of the intermediate spindle 20. The ratchet seats 21 are used to rotationally support the two ends of the intermediate spindle 20.

[0027] Among them, two groups of transition sprockets 15, tensioning sprockets 16 and driving sprockets 17 are each provided. An upper tank lifting cylinder 31 is fixedly installed on the trapezoidal movable frame 7 at the side of the upper tank lifting ear 28. A cylinder wheel seat 32 is fixedly provided at the lower end of the upper tank lifting cylinder 31. A lifting wheel 33 is rotatably connected to the cylinder wheel seat 32. The upper tank lifting cylinder 31 is used to provide power support for the lifting and lowering adjustment of the upper tank body 3.

[0028] The transition sprocket 15, the lifting wheel 33, and the upper tank lifting ear 28 are connected by a second chain 35. One end of the second chain 35 is fixedly connected to the chain fixing hole 29 provided on the upper tank lifting ear 28, and the other end is fixedly connected to the cylinder wheel seat 32. The second chain 35, the transition sprocket 15, and the lifting wheel 33 are in a sprocket and chain matching state to ensure that the lifting wheel 33 can drive the transition sprocket 15 to rotate during the lifting and moving process.

[0029] A lifting track 36 is fixedly installed on the inner side of the trapezoidal movable frame 7, and an upper tank lifting seat 30 is installed on the upper tank lifting ear 28. The upper tank lifting seat 30 includes a lifting matching wheel 37 and a limiting side wheel 38. The lifting matching wheel 37 cooperates with the lifting track 36. Safety limiting plates 39 are provided on both sides of the lifting track 36. The limiting side wheel 38 cooperates with the safety limiting plate 39 to ensure the stability of the lifting and adjusting process of the upper tank body 3.

[0030] The lower part of the upper tank body 3 cooperates with the upper support rail 6 through the movable track wheel. A hydraulic cylinder connecting seat 11 is fixedly provided on the outer side of the lower tank body 1. The bottom surface of the hydraulic cylinder connecting seat 11 is fixedly connected to the lower lifting cylinder 8. The lower lifting cylinder 8 is fixedly installed on the lower translation vehicle plate 4. The lower tank guide column 9 is fixedly provided near the four corners of the lower translation vehicle plate 4. The upper part of the lower tank guide column 9 is equipped with a guide column bracket 10 to ensure the stability of the lifting and lowering adjustment of the lower tank body 1.

[0031] The lower translation vehicle plate 4 is installed on the lower support rail 5 through the cooperation of the rail wheel. The upper end of the lower tank body 1 and the lower end of the upper tank body 3 are both equipped with a locking flange ring 12. The specifications of the locking flange ring 12 match the locking ring 13 and are used for fixed connection between the lower tank body 1 and the intermediate tank body 2, and the upper tank body 3 and the intermediate tank body 2.

[0032] When the lower support rail 6 is moved along the lower support rail 5, the lower lifting cylinder 8 is in a retracted state, so that the top position of the lower tank body 1 is lower than the position of the locking ring 13 under the intermediate tank body 2 to avoid interference during the movement. The device is equipped with a moving positioning device, which will not be described in detail in the prior art.

[0033] When the upper tank body 3 needs to move downward, the self-locking cylinder 40 is first started, and the telescopic rod of the self-locking cylinder 40 is extended, driving the reverse pawl 23 to rotate upward along the rotating shaft 41, releasing the cooperation between the reverse pawl 23 and the reverse ratchet 22, and thus releasing the self-locking restriction, and the upper tank lifting cylinder 31 contracts, driving the lower end of the second chain 35 to move upward, and the second chain 35 cooperates with the transition sprocket 15. During the transmission process of the second chain 35, the filter sprocket is driven to rotate, and the other end of the second chain 35 is fixedly connected to the upper tank lifting ear 28 on the upper tank body 3, thereby driving the upper tank body 3 to move downward, and locking with the intermediate tank body 2, and the self-locking cylinder 40 is reset, and the reverse ratchet 22 and the reverse pawl 23 are adjusted to the self-locking state.

[0034] After the upper, middle, and lower tanks are joined, the system first evacuates the entire tank body, then pressurizes the lower tank with compressed air, causing the molten metal to rise to the upper tank model. After the liquid is raised, the upper and lower tanks are simultaneously pressurized with compressed air to maintain a constant pressure differential between the upper and lower tanks. The molten metal solidifies under pressure. After the liquid is raised, the upper tank is cooled and pressurized with liquid nitrogen, while the lower tank is passed through compressed air to maintain a constant pressure differential between the upper and lower tanks. The molten metal solidifies under the pressure of liquid nitrogen vaporization and is cooled with liquid nitrogen. The casting control system is the scope of protection of another subject application and will not be described in detail here.

[0035] When the upper tank body 3 is separated from the intermediate tank body 2 and raised for adjustment, the upper tank lifting cylinder 31 extends, driving the cylinder wheel seat 32 and the lifting wheel 33 to move downward, and the cylinder wheel seat 32 and the lifting wheel 33 drive the lower end of the chain 2 35 to move downward synchronously. Since the chain 2 35 cooperates with the transition sprocket 15, it will drive the transition sprocket 15 to rotate, and the other end of the chain 2 35 is fixedly connected to the upper tank lifting ear 28. When one end of the chain 2 35 drops, the other end rises, thereby driving the upper tank body 3 to move upward. During the rotation of the transition sprocket 15, the driving sprocket 17 is driven to rotate through the chain 1 34. The driving sprocket 17 drives the side spindle 18 and the intermediate spindle 20 to rotate, and then drives the reverse ratchet 22 to rotate. When the upper tank body 3 is rising, the lifting system fails and the upper tank body 3 falls suddenly. The cooperation between the reverse ratchet 22 and the reverse pawl 23 can effectively lock the protection;

[0036] The lower support track 5 is provided with three workstations, namely, the horizontal shift position, the tank closing position, and the smelting position. The multi-station coordinated operation can effectively improve the production efficiency. The upper support track 6 is equipped with a supporting structure, which is fixedly installed on the ground, not shown in the drawings;

[0037] The lightweight alloy casting equipment of the present invention is a three-section structural design, in which the middle tank body 2 is a fixed structure, the lower tank body 1 is a lifting and X-direction translation structure, and the upper tank body 3 is a lifting and Y-direction translation structure. The three tank bodies are fixedly connected by the cooperation of the locking flange ring 12 and the locking ring 13. After casting, the three sections are separated to facilitate rapid demolding of parts. The upper tank body 3 lifting device is equipped with a falling self-locking structure, which is limited by the cooperation of the reverse ratchet 22 and the reverse pawl 23 to improve the safety of the upper tank body 3 lifting system. Upper tank lifting ears 28 and an upper tank lifting seat 30 are provided on both sides of the upper tank body 3. Relying on the cooperation of the upper tank lifting seat 30 with the lifting rail 36 and the safety limit plate 39, the stability of the lifting process of the upper tank body 3 is effectively improved.

Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
