TECHNICAL FIELD

[0002] O-shaped sealing rings are key sealing components on aircraft and other aircrafts, and the forming precision and performance thereof directly affect the operation safety and reliability of the aircraft. The production efficiency and quality of the sealing rings are continuously improved in the current aviation field, which promotes the continuous optimization of related forming devices. The existing sealing ring forming devices for aircrafts mainly use rubber as raw material, and batch production is realized through a mold heating melting and extrusion forming process. The core lies in ensuring the uniformity of rubber raw material melting and the consistency of forming, so as to meet the strict standards of aviation level components.
[0003] The existing sealing ring forming device for aircraft mainly comprises a base, a lower mold, an upper mold, a cross beam, an extrusion block and a driving cylinder. The lower mold is provided with a cavity on the top surface, and a heating element is arranged inside. The bottom surface of the upper mold is fixedly provided with a core, and the extrusion block slidingly arranged on the cross beam is driven downward by the driving cylinder. When the device is running, a plurality of rubber strips are placed in the cavity one by one, and then the upper mold is closed. The heating element is started synchronously to melt the rubber strips, and the extrusion block is pressed down to complete the forming of the sealing ring. After forming, the extrusion block is reset, the mold is opened, and the finished product is taken out, which can enter the next batch production cycle to realize continuous operation.
[0004] After the demolding of the last batch of workpieces, the inner wall of the cavity still maintains a high temperature due to the residual heat of the heating element. In order to shorten the production cycle, the workers usually place the next batch of rubber strips into the cavity one by one immediately after demolding. However, due to the time difference in placing the rubber strips, when the last rubber strip of the batch is placed, the first rubber strip placed earliest has already deformed and melted in advance under the action of the residual heat of the cavity. This leads to inconsistent initial melting state of the whole batch of rubber strips, and the rubber strips are unevenly heated and obviously different in shaping during the subsequent heating and extrusion forming process, which finally affects the size precision and sealing performance of the sealing ring. In severe cases, the product may be scrapped, and there is an obvious need for improvement. SUMMARY
