[0026] Please refer to Figures 1-4 The present application provides a technical scheme: a composite material forming tool for aviation, comprising a support platform 1 and a mold 4, a moving seat 2 is movably arranged inside the support platform 1, specifically, a hydraulic cylinder 14 is fixedly installed at the bottom end of the inside of the support platform 1, and the telescopic end of the hydraulic cylinder 14 is fixedly connected with the bottom surface of the moving seat 2.

[0027] The moving seat 2 is fixedly connected with a support frame 3 on both sides, and a plurality of non-slip strips 13 are fixedly installed on the upper end surface of the support frame 3. By arranging the non-slip strips 13, the friction between the mold 4 and the support frame 3 is improved, and the stability of the mold 4 is further improved.

[0028] The mold 4 is limitingly arranged on the upper end surface of the moving seat 2 and the support frame 3, and a limit sliding groove 5 is formed on the upper end surface of the moving seat 2. The clamping plates 6 are limitingly and slidably arranged on both sides of the limit sliding groove 5, and the non-slip pads 12 are fixedly installed on the opposite surfaces of the two clamping plates 6 to improve the clamping force of the clamping plates 6.

[0029] Specifically, a two-way screw 8 is rotatably installed in the limit sliding groove 5, the two ends of the two-way screw 8 extend to the outside of the moving seat 2, sliding blocks 9 are limitingly and slidably installed on both sides of the inside of the limit sliding groove 5, the clamping plates 6 are fixedly installed on the top ends of the sliding blocks 9, and the two sliding blocks 9 are threadedly connected with the two ends of the two-way screw 8.

[0030] More specifically, the two ends of the bidirectional screw 8 are fixedly connected with gears 10, and the inner walls of the support table 1 are fixedly installed with toothed plates 11 on both sides, and the gears 10 are meshed and connected with the corresponding toothed plates 11.

[0031] The inner sides of the support table 1 are fixedly installed with fixed plates 7, and the fixed plates 7 are provided with pressing assemblies. The pressing assembly comprises a cylinder 15 and a pressing rod 16. The cylinder 15 is fixedly installed on the inner bottom surface of the support table 1, the telescopic end of the cylinder 15 is slidably penetrated through the upper end surface of the fixed plate 7, the telescopic end of the cylinder 15 is rotatably installed with the pressing rod 16, and the other end of the pressing rod 16 is abuttingly matched with the upper end surface of the mold 4.

[0032] Working principle:

[0033] In the actual operation process, first, the mold 4 is placed on the upper end surfaces of the moving seat 2 and the support frame 3. Then, the hydraulic cylinder 14 is started, and the telescopic end of the hydraulic cylinder 14 starts to shrink, which directly drives the downward movement of the moving seat 2. Further, the support frame 3 is also synchronously moved downward, thereby bringing the mold 4 to descend.

[0034] With the descent of the moving seat 2, the bidirectional screw 8 installed thereon is synchronously moved downward. The two ends of the bidirectional screw 8 are respectively provided with gears 10, and the gears 10 are meshed with the corresponding toothed plates 11 during the downward movement. Thus, the gears 10 are rotated while moving downward due to the interaction with the toothed plates. The rotation of the gears 10 drives the rotation of the bidirectional screw 8, and the rotation of the bidirectional screw 8 drives the two sliding blocks 9 to move closer to each other through the interaction of the threads.

[0035] The movement of the sliding blocks 9 is a key step for clamping the mold 4. With the mutual approach of the sliding blocks 9, they drive the clamping plates 6 to synchronously move, so that the clamping plates 6 on both sides gradually approach the mold 4 and finally clamp the mold 4 firmly.

[0036] When the clamping plates 6 on both sides clamp the mold 4 in place, the mold 4 has already fallen to a position where it is fully matched with the two pressing rods 16. At this time, the cylinder 15 is started, and the telescopic end of the cylinder starts to eject, which drives the end of the pressing rod 16 away from the cylinder to gradually approach and finally abut against the upper end surface of the mold 4. The design of the pressing rod 16 not only provides additional support for the mold 4, but also ensures the stability and safety of the mold 4 during the processing.

[0037] The embodiments of the utility model are described in detail in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by ordinary skilled persons in the technical field without departing from the purpose of the utility model.
