Description

Technical Field

[0001] The invention relates to the technical field of cabin casting, and in particular to a bottom plate casting structure used for cabin casting. Background Art

[0002] Aircraft refers to a flying object that is manufactured by humans, can take off the ground, fly in space, and is controlled by humans, and flies within or outside the atmosphere. Aircraft are mainly divided into: aircraft, spacecraft, rockets and missiles. The cabin of the aircraft is cast in one piece using aluminum alloy materials. During production, a mold needs to be used for casting to ensure that the overall structure of the cabin is firm. At present, when manufacturing the cabin parts of the aircraft shell, because the internal quality requirements are often relatively high, for thin-walled and complex cabin castings, the pressure difference casting process is often used.

[0003] After searching, a Chinese invention patent disclosed a bottom plate casting structure for cabin casting with a publication number of CN116586594A, which includes a bottom frame, a mold core installed at the center of the bottom frame, and an outer mold plate arranged outside the mold core. The outer mold plate is spliced ​​by four arc-shaped plates with fan-shaped structures. A reinforcement mechanism is arranged on the outside of the outer mold plate, and a heat preservation mechanism is arranged on the inner wall of the outer heat dissipation cavity close to the outside. A top casting cover plate is arranged on the top of the mold core and the outer mold plate, and a bubble detection mechanism is arranged at the center of the bottom frame. The bottom plate casting structure for cabin casting improves the heat dissipation capacity and makes the heat dissipation uniform by adopting the arrangement of the inner heat dissipation cavity, the outer heat dissipation cavity and the external circulation refrigeration water tank. The outer mold plate is arranged in a spliced ​​shape, which is convenient for disassembly and removal. The bubble detection mechanism and the bubble removal mechanism are arranged to prevent the casting from being scrapped due to bubbles in the casting, thereby improving the qualified rate. The arrangement of the heat preservation mechanism ensures that the internal crystal structure of the casting is completely the most suitable structure.

[0004] The existing casting structure has the following problems: the casting mold needs to be manually installed and disassembled by personnel, the work efficiency is low, and the sealing cannot be guaranteed. In addition, the mold outside the device is only provided with a heat dissipation cavity, so the heat dissipation efficiency is low and the temperature distribution is uneven. Therefore, when personnel disassemble, it is easy to cause harm to personnel.

[0005] Therefore, the existing bottom plate casting structure used for cabin casting cannot meet the needs in actual use, so there is an urgent need for improved technology in the market to solve the above problems. Summary of the invention

[0046] Working principle:

[0047] During operation, the driving structure 3 is started to rotate the output end of the driving structure 3. Since the output end of the driving motor 31 is fixedly connected to the front rotating rod 23 of the bottom plate 1, the front rotating rod 23 rotates, thereby rotating the pulley 1 32 and the belt 1 33, so the sliders 41 approach each other, thereby making the two sides 51 plugged into each other and sleeved on the outer surface of the inner mold 6, and then starting the lifting driving structure 9, so that the output end of the lifting motor 91 rotates, so the right worm 83 rotates, thereby rotating the pulley 2 92 and the belt 2 93, so the right worm 83 rotates, since the worm 83 and the worm wheel 81 are meshed with each other, the worm wheel 81 rotates, further rotating the threaded rod 101. At this time, the threaded sleeve 102 is limited by the connecting frame 103, so that the height of the threaded sleeve 102 and the connecting frame 103 is lowered, so that the casting cover plate 113 is movably connected to the upper end surface of the outer mold 5.

[0048] At this time, the personnel inject the metal solution into the top casting structure 11 through the casting port 73. At this time, the solution is evenly distributed between the outer mold 5 and the inner mold 6 through the telescopic inner tube 111 and the telescopic outer tube 112 under the action of gravity.

[0049] When cooling is required, the cooling water tank pipeline is connected to the connecting pipe 43, so that the coolant is evenly distributed in the inner cavity of the mold core 61 through the side wall circulation groove 63 and the top plate circulation 64, and then the condensed water in the inner cavity of the mold core 61 is circulated through the guide groove 62, so that the inner mold 6 is cooled after casting, and at the same time, the outer casting plate 51 dissipates heat and cools the outer casting plate 51 through the heat conducting fins 52 and the heat dissipation plate 53, thereby accelerating the cooling rate of the casting.

[0050] As a result, the output end of the lifting motor 91 is reversed, so the worm 83, the pulley 92 and the belt 93 rotate in the opposite direction, causing the worm wheel 81 and the threaded rod 101 to rotate in the opposite direction, thereby increasing the height of the threaded sleeve 102, the connecting frame 103 and the top casting structure 11, thereby raising the casting cover plate 113 and separating it, and then starting the driving structure 3, causing the output end of the driving motor 31 to be reversed, so the rotating rod 23, the pulley 1 32 and the belt 1 33 rotate in the opposite direction, and then under the action of the rotating rod 23, the slider 41 and the outer casting plate 51 slide towards each other, thereby facilitating personnel to take the casting.
