[0001] The utility model relates to the technical field of airtight testing of die-cast workpieces, in particular to an airtight testing device for die-cast workpieces. Background Technique

[0002] A die-cast workpiece is a workpiece produced by pressure processing. After melting the metal and pouring it into the corresponding production mold, it is formed after the metal in the production mold cools under external high pressure. After the die-cast workpiece is produced, an airtight testing device is required to test the airtightness of the die-cast workpiece, so as to ensure the quality of the die-cast workpiece and prevent air leakage during use, ensuring the production and use of the die-cast workpiece.

[0003] For traditional airtight testing devices for die-cast workpieces, when testing die-cast workpieces, the gas introduced into them for detection needs to ensure the purity of the gas, so as to avoid impurities in the gas adhering to the inside of the die-cast workpiece after the test, causing dirt on the die-cast workpiece and affecting subsequent use. Therefore, we propose an airtight testing device for die-cast workpieces to improve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an airtight testing device for die-cast workpieces to solve the problems raised in the above background technique.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1: Please refer to Figures 1-4, A closed testing device for die-cast workpieces, including a detection device 1. There is a test bench 2 on one side of the detection device 1. At the top inside the test bench 2, there is an inner cavity 17. There is a filter seat 18 in the inner cavity 17. On both sides inside the filter seat 18, there are fixed clamping seats 21. Inside each clamping seat 21, there is a movable filter net 19. On both sides at the rear end of the filter net 19, there are fixed connecting rods 20. One side of the filter seat 18 is hingedly installed with a plate body 16. At the top of the filter seat 18, there is an air pipe 7. There is a hole body 22 outside the air pipe 7, and the hole body 22 is opened at the top inside the detection device 1. On both sides at the top of the detection device 1, there are fixed support rods 3. At the top of the support rods 3, there is a top plate 10. Inside the top plate 10, there is a telescopic cylinder 5. At the bottom end of the telescopic cylinder 5, there is a pressing block 15, and at the bottom end of the pressing block 15, there is a pressing plate 4. A test seat 9 is movably arranged at the top of the detection device 1, and a die-cast part 8 is movably arranged inside the test seat 9. There are two groups of filter nets 19. Both groups of filter nets 19 form a clamping structure with the filter seat 18 through the clamping seats 21, which is convenient for disassembling, assembling and cleaning the filter nets 19. The cross-section of the test seat 9 is larger than that of the die-cast part 8. A clamping structure is formed between the test seat 9 and the die-cast part 8. The design of the clamping structure makes the sealing between the test seat 9 and the die-cast part 8 stronger and the detection effect better;

[0024] Specifically, as Figure 1 and Figure 3 shown, when the gas enters the inside of the die-cast part 8, the gas will first enter the inside of the filter seat 18. After the two groups of filter nets 19 inside the filter seat 18 filter the gas, the clean gas enters the inside of the die-cast part 8 through the air pipe 7 for closed testing. Subsequently, the plate body 16 can be flipped to open the filter seat 18, and then hold the connecting rod 20 and pull the filter net 19 towards one end to make it slide out of the inside of the clamping seat 21, and then clean the connecting rod 20 and install it back in place for continued use.

[0025] Embodiment 2: On the left and right sides at the top of the detection device 1, there are fixed mounting plates 13. Inside each mounting plate 13, there is a movable threaded rod 6, and on one side of each threaded rod 6, there is a clamping plate 12. There are four groups of clamping plates 12. The four groups of clamping plates 12 are symmetrically distributed about the central axis of the test seat 9. The symmetrically distributed four groups of clamping plates 12 make the installation of the test seat 9 above the detection device 1 more stable;

[0026] Specifically, as Figure 1 and Figure 2 shown, when replacing the test seat 9, rotate the threaded rod 6 to pull the clamping plate 12 to move to one side to open the limit on the test seat 9, then take out the test seat 9 and replace it with the test seat 9 that needs to be used and place it above the detection device 1, and then rotate the threaded rod 6 in the reverse direction to push the clamping plate 12 to fit against the outer side wall of the test seat 9 to lock it, so that the test seat 9 is installed.

[0027] Embodiment 3: A locking block 11 is fixed to the bottom end of the outer side wall of the support rod 3. Connecting blocks 25 are fixed to one side of each locking block 11. Rotating shafts 24 are installed inside the connecting blocks 25. Locking rings 14 are movably arranged on the outer side walls of the rotating shafts 24. Locking rings 14 are fixed to both sides of the pressing plate 4. There are four groups of locking rings 14, and the four groups of locking rings 14 are symmetrically distributed about the central axis of the pressing plate 4, making the pressing plate 4 press the die-casting part 8 more stably. The cross-section of the locking ring 14 is larger than the cross-section of the clamping block 23. A clamping structure is formed between the locking ring 14 and the clamping block 23. The design of the clamping structure enables the pressing plate 4 and the locking block 11 to be stably connected;

[0028] Specifically, as Figure 1 , Figure 2 and Figure 4 shown, when the telescopic air cylinder 5 pushes the pressing block 15 and the pressing plate 4 to fit above the die-casting part 8 to press the die-casting part 8, then turn the locking ring 14 and sleeved it on the outer side wall of the corresponding clamping block 23 above it, so that the pressing plate 4 and the locking block 11 are stably connected together, thus making the pressing of the die-casting part 8 more stable.

[0029] Working principle: When the present utility model is in use, take the die-casting part 8 to be tested and place it inside the test seat 9. Start the telescopic air cylinder 5 to push the pressing block 15 and the pressing plate 4 to move downward together so that the pressing plate 4 fits above the die-casting part 8 to apply pressure to it. After the pressure application is completed, turn the locking ring 14 and sleeved it on the outer side wall of the corresponding clamping block 23 above it, so that the pressing plate 4 and the locking block 11 are stably connected together to stably apply pressure to the die-casting part 8, making the die-casting part 8 and the test seat 9 tightly engaged together. Then start the detection device 1 to introduce gas into the die-casting part 8 through the air pipe 7 for airtight testing. When testing, the gas will first enter the inside of the filter seat 18. The two filter meshes 19 inside the filter seat 18 filter the gas, and then the clean gas enters the die-casting part 8 through the air pipe 7. The corresponding data during the testing is displayed by the detection device 1.
