[0025] As Figure 4 shown, a plurality of sliding columns 23 are fixedly connected inside the first disassembly box 2. The outer surfaces of the plurality of sliding columns 23 are all in sliding connection with the inner wall of the sliding plate 20. Through the plurality of sliding columns 23, the sliding direction of the sliding plate 20 can be restricted to prevent the sliding plate 20 from tilting when moving downward.

The output end of the cylinder 16 is fixedly connected to a lifting platform 14. A disassembly box 2 is fixedly installed at the lower end of the lifting platform 14. An airtightness detection mold 2 is fixedly installed at the lower end of the disassembly box 2. By starting the cylinder 16, the airtightness detection mold 2 is brought into contact with the airtightness detection mold 1 to ensure that the plastic part is in a sealed space. There is a gas detection structure in both the airtightness detection mold 2 and the airtightness detection mold 1. The structures in the disassembly box 2 and the disassembly box 1 are the same.

[0029] As Figure 3 As shown in the figure, positioning rods 17 are fixedly connected to both sides of the upper end of the lifting platform 14. The outer surfaces of the two positioning rods 17 are slidably connected to the inner wall of the installation frame 13. The structural design of the positioning rods 17 prevents misalignment when the airtightness detection mold 2 is in contact with the airtightness detection mold 1 during long-term use.

[0030] The present utility model provides an airtightness detection device for plastic part processing. The specific working principle is as follows:

[0031] When performing airtightness detection on plastic parts, first place the plastic part on the airtightness detection mold 3. Then, start the air cylinder 16 to make the airtightness detection mold 2 18 fit with the airtightness detection mold 1 3. Next, start the airtightness detector 12 and fill the plastic part on the airtightness detection mold 1 3 with gas through the air filling pipeline 15. The airtightness detection mold 1 3 and the airtightness detection mold 2 18 detect whether there is air leakage. When it is necessary to detect plastic parts of different models, pull the rotating block 24 to slide the rotating block 24 out of the fixed block 25, release the restriction of the sliding plate 20, press down the sliding plate 20 to make the connecting rod 2 6 slide in the disassembly box 1 2, and then drive the convex block of the connecting rod 2 6 to abut against one end of the special-shaped block 7. The special-shaped block 7 slides in the T-shaped installation groove 9 to release the restriction of the connecting rod 1 5, so as to remove the airtightness detection mold 1 3 from the disassembly box 1 2. Then, insert the connecting rod 1 5 of the new airtightness detection mold 1 3 into the fixed groove 10, and the replacement of the airtightness detection mold 1 3 of different models can be completed. After the replacement is completed, rotate the rotating block 24, and the inner wall side of the rotating block 24 is stuck on the fixed block 25 to fix the sliding plate 20 in place. Then, repeat the above operation to detect the plastic part.
