Description

Technical Field

[0001] The utility model relates to the technical field of aerospace vehicle processing, in particular to a die flipping device for aerospace vehicle processing. Background Art

[0002] The die for aerospace vehicle processing is a key tool in the field of aerospace manufacturing. It plays a crucial role in ensuring the high precision and high performance of aerospace vehicle parts. Such dies usually adopt advanced materials and exquisite manufacturing processes to meet extremely demanding requirements. In terms of design, the die needs to fully consider the complex shapes and high-precision dimensional requirements of the aerospace vehicle parts, and use advanced computer-aided design and simulation technologies for precise structural optimization. During the manufacturing process, materials with high strength, high temperature resistance, wear resistance and good stability are selected, such as special alloys or ceramic matrix composite materials, etc. At the same time, ultra-precision machining technologies are adopted to ensure that the flatness and roughness of the die surface reach extremely high standards.

[0003] For example, the utility model with the application number CN205393514U discloses a die flipping device, which includes a platform support. The platform support includes legs and a cross beam. An electric motor, a flipping mechanism and a platform are installed on the cross beam. The flipping mechanism includes an input gear and an output gear that mesh with each other. The platform includes a central shaft and a die mounting platform connected to the central shaft for mounting the die. A fixture for clamping the die is arranged on the die mounting platform. The input gear is sleeved on the output shaft of the electric motor, and the output gear is sleeved on the central shaft of the platform. The die flipping device provided by the utility model enables the die preparation operator to directly operate on the die flipping device. By using the die flipping device, the utilization rate of the overhead crane is saved, the failure rate of the overhead crane is reduced, and the work efficiency is improved.

[0004] Similar to the above application, there are still the following deficiencies: when injecting parts, the die will shake. Summary of the Utility Model

[0005] The utility model discloses a die flipping device for aerospace vehicle processing, aiming to solve the technical problem that the die will shake when injecting parts.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A mold flipping device for aerospace vehicle processing, comprising a frame. A fixed frame is fixedly connected to the top of the frame. A limiting frame is fixedly connected to the upper surface of the fixed frame. A rotating rod is rotatably connected to the inner cavity of the limiting frame. A rotating ring is fixedly connected to the outer surface of the rotating rod. The rotating ring is frictionally adapted to the inner wall of the limiting frame. A mold box is fixedly connected to the end of the rotating rod. A clamping plate is fixedly connected to the end of the rotating rod away from the mold box. A positioning mechanism is arranged in the inner cavity of the frame. The positioning mechanism includes a first sliding rod which is slidably connected in the inner cavity of the frame. A clamping column is fixedly connected to the top of the first sliding rod. A sealing pad is fixedly connected to the outer surface of the clamping column. The sealing pad is frictionally adapted to the inner wall of the clamping plate.

[0008] By setting the limiting frame, the rotating rod can be limited. By setting the rotating ring, it can friction with the inner wall of the limiting frame, so that the rotating rod can rotate stably in the inner cavity of the limiting frame, and then the mold box can rotate stably. By setting the clamping plate, it can cooperate with the positioning mechanism, so that the mold box does not rotate. By setting the positioning mechanism, it is convenient for the operator to limit the mold box, so that the mold box does not rotate during injection molding, and when the mold box needs to be flipped, the mold box is no longer subject to resistance, thus achieving the flipping effect of the mold box.

[0009] In a preferred solution, a clamping ring is fixedly connected to the outer side surface of the mold box. A support rod is fixedly connected to the outer surface of the frame. A clamping tube is fixedly connected to the top of the support rod. A clamping rod is slidably connected in the inner cavity of the clamping tube. The end of the clamping rod is frictionally adapted to the inner wall of the clamping ring.

[0010] By setting the clamping ring and the clamping tube, the clamping rod can be limited, so that the mold box and the frame remain relatively stationary. By setting the clamping rod, it can be inserted into the inner cavities of the clamping tube and the clamping ring, so that the mold box and the frame remain relatively stationary.

[0011] In a preferred solution, a connecting plate is fixedly connected to the bottom end of the first sliding rod. A connecting frame is fixedly connected to the lower surface of the connecting plate. A pedal is fixedly connected to the outer side surface of the connecting frame. The positioning mechanism further includes a limiting tube which symmetrically penetrates through the outer surface of the frame. A second sliding rod is slidably connected in the inner cavity of the limiting tube. The bottom end of the second sliding rod is fixedly connected to the upper surface of the connecting plate. A connecting rod is fixedly connected to the outer surface of the limiting tube. A blocking plate is fixedly connected to the top end of the connecting rod. A spring is fixedly connected to the lower surface of the blocking plate. The bottom end of the spring is fixedly connected to the upper surface of the second sliding rod. The number of the sealing pads is several, and several of the sealing pads are evenly distributed.

[0012] By setting the connecting plate and the connecting frame, when the first sliding rod moves, the pedal can be moved together. By setting the pedal, it is convenient for the operator to move the first sliding rod. By setting the limiting tube, the second sliding rod can be limited, so that the second sliding rod can move vertically up and down in the inner cavity of the limiting tube. By setting the baffle plate and the spring, a pulling force can be generated, so that the second sliding rod is always subjected to an upward pulling force, and finally the second sliding rod moves upward. By setting the sealing gasket, the positioning column can be tightly inserted into the inner cavity of the positioning plate.

[0013] As can be seen from the above, a mold flipping device for aerospace vehicle processing has the following improvements and advantages compared with the prior art;

[0014] First: By setting the limiting frame, the rotating rod can be limited. By setting the rotating ring, it can rub against the inner wall of the limiting frame, so that the rotating rod can rotate stably in the inner cavity of the limiting frame, and then the mold box can rotate stably. By setting the positioning plate, it can cooperate with the positioning mechanism, so that the mold box does not rotate.

[0015] Second: By setting the positioning mechanism, it is convenient for the operator to limit the mold box, so that the mold box does not rotate during injection molding, and when the mold box needs to be flipped, the mold box is no longer subjected to the blocking force, so as to achieve the flipping effect of the mold box.
