[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See attached document Figure 1-5 A rubber sealing ring pressure testing device includes a base 1, a mold 2 on the top of the base 1, and several neatly arranged placement slots 3 on the top of the mold 2 for placing sealing rings. The sealing rings placed in the placement slots 3 are less likely to shake when under pressure, which can improve the accuracy of the test. A vertical groove 4 is opened at the bottom of the placement slots 3, and a lifting block 5 is provided in the vertical groove 4. The lifting block 5 can move up and down in the vertical groove 4. A pushing unit is provided inside the mold 2 for synchronously pushing the several lifting blocks 5 to move upwards. After the test is completed, the pushing unit works to make the several lifting blocks 5 move upwards synchronously, pushing out the sealing rings placed in the placement slots 3, which facilitates the removal of the sealing rings and improves the test efficiency.

[0026] In this embodiment, the pushing unit includes a pull-out frame 6. The mold 2 has a sliding groove 9 inside for the pull-out frame 6 to slide. The front end of the sliding groove 9 is a cross-shaped groove, and the rear end is two long grooves to ensure that the pull-out frame 6 can slide stably without deviation.

[0027] The top of the pull-out bracket 6 is provided with several push blocks 7 corresponding to the bottom of the lifting block 5. Each push block 7 includes a triangular block at the front end and a rectangular block at the rear end. The opposing surfaces of the lifting block 5 and the push blocks 7 are mutually cooperating inclined surfaces. When the pull-out bracket 6 slides in the slide groove 9, the push blocks 7 move accordingly. Their inclined surfaces press against the inclined surfaces of the lifting blocks 5, thereby pushing the lifting blocks 5 upward. This achieves the synchronous pushing of several lifting blocks 5 upward to push out the sealing ring. The structure is simple and the efficiency is high.

[0028] In this embodiment, a spring 8 is connected between the pull-out frame 6 and the mold 2. After the pull-out frame 6 completes the pushing action, the elastic restoring force of the spring 8 is used to pull the pull-out frame 6 back to the initial position, preparing for the next pushing operation. This realizes the automatic reset of the pushing unit and improves the convenience of operation.

[0029] In this embodiment, a pair of columns 10 are provided on the base 1. The top of the pair of columns 10 is connected to a top plate 11. A cylinder 12 is provided on the top of the top plate 11 as a power source. A pressure plate 13 is provided at the bottom output end of the cylinder 12. Several pressure columns 14 are provided at the bottom of the pressure plate 13 corresponding to the placement groove 3. A pressure sensor 15 is provided at the bottom of the pressure column 14 to sense the pressure signal. It can measure the pressure on the sealing ring in real time and accurately, and convert the pressure signal into an electrical signal for transmission, so as to analyze and judge the pressure performance of the sealing ring in the future.

[0030] In this embodiment, both the placement groove 3 and the pressure sensor 15 are annular structures adapted to the sealing ring, which facilitates better fitting of the sealing ring shape, making the pressure application more uniform and improving the accuracy of detection.

[0031] Working principle: When performing pressure testing on rubber seals, the rubber seals to be tested are first placed in the placement groove 3 at the top of the mold 2. Then, the cylinder 12 is started. The output end of the cylinder 12 pushes the pressure plate 13 downward. The pressure plate 13 drives the pressure column 14 and the pressure sensor 15 to move downward together, so that the pressure column 14 presses on the seal. The pressure sensor 15 senses the pressure signal in real time and transmits the signal.

[0032] After the test is completed, the cylinder 12 drives the pressure plate 13 to move upward and reset. Then, the pull-out bracket 6 is pulled, and the push block 7 on the pull-out bracket 6 pushes the lifting block 5 upward through the inclined surface to push out the sealing ring in the placement groove 3, completing the removal of the sealing ring. Finally, the pull-out bracket 6 is released, and the spring 8 pulls the pull-out bracket 6 back to the initial position, preparing for the next test.
