Description

Technical Field

[0001] The utility model belongs to the technical field of waterproof performance detection devices, and in particular relates to a waterproof performance detection device for automotive electronic products. Background Art

[0002] An airtightness tester is an industrial tool used to test the airtightness of a product. It does this by inflating the product or placing it in a contoured mold to inflate it, and then measuring the pressure changes in the sealed environment to determine whether the product's airtightness meets the requirements. This testing method can simulate water pressure and is used to test the product's waterproof performance.

[0003] After the existing airtightness detector completes the measurement, due to the radians and curved surfaces on the appearance of some products, it is difficult to take out the products placed in the mold, which delays the measurement time and affects the work efficiency. Secondly, the existing mold sealing groove has no buffer distance, which causes the sealing ring to be over-extruded and deformed, and thus cannot better fit the sealing groove, resulting in air leakage during the measurement process, affecting the accuracy of the measurement results. The existing airtightness detector has no cooling device. Multiple measurements will increase the temperature inside the mold, thereby affecting the change in the air pressure inside the mold, and then affecting the measurement results. It is necessary to wait for the temperature inside the mold to return to normal temperature before measuring again, affecting the measurement efficiency. Utility Model Content

[0032] The sealing mechanism 4 includes a first mold 401, the bottom of which is connected to the top of the detection device body 1, a travel groove 402 is provided at the top of the first mold 401, a plurality of first springs 405 are connected to the inner wall of the travel groove 402, and one end of the plurality of first springs 405 is connected to the same pad 403, a sealing ring 404 is connected to the top of the pad 403, the cooling mechanism 5 includes a fixed plate 502, the bottom of the fixed plate 502 is connected to the top of the support plate 2, a cylinder 501 is connected to the top of the fixed plate 502, the cylinder 501 push rod passes through one side of the fixed plate 502 and is connected to the second mold 504, both sides of the second mold 504 are connected to connecting plates 505, the top of the connecting plate 505 is connected to an airbag 503, and the top of the airbag 503 is connected to the bottom of the fixed plate 502, the bottom of the airbag 503 is connected to an air outlet pipe 506, and one end of the air outlet pipe 506 passes through one side of the connecting plate 505, and a sealing groove 507 is provided at the bottom of the second mold 504.

[0033] The specific implementation method is as follows: by setting the travel groove 402, since the travel groove 402 has a certain buffer length, the pad 403 and the sealing ring 404 can slide in the travel groove 402, so that the sealing ring 404 can have a buffer distance when it is squeezed, thereby avoiding the irreversible deformation of the sealing ring 404 due to excessive squeezing, and improving the service life of the sealing ring 404. At the same time, the deformation of the sealing ring 404 will not make the next measurement inaccurate. By setting the first spring 405, the upward elastic force of the first spring 405 allows the sealing ring 404 to be tightly The sealing groove 507 fits tightly, thereby improving the air tightness of the mold and the measurement accuracy of the device. The upward movement of the cylinder 501 push rod drives the second mold 504 to move upward, and the upward movement of the second mold 504 drives the connecting plate 505 to move upward. The upward movement of the connecting plate 505 squeezes the airbag 503, so that the airbag 503 blows the gas out of the outlet pipe 506 and blows it into the first mold 401, thereby quickly reducing the temperature in the first mold 401, accelerating the speed at which the first mold 401 returns to normal temperature, reducing the waiting time, and thus improving the measurement efficiency.

[0034] An extrusion mechanism 6 is provided on both sides of the first mold 401. The extrusion mechanism 6 includes a slide groove 603.

When the second mold 504 and the first mold 401 are fitted, the first spring 405 uses the elastic force to make the pad 403 drive the sealing ring 404 to fit tightly upward in the sealing groove 507, thereby improving the sealing effect. After the measurement is completed, the push rod of the cylinder 501 drives the second mold 504 to move upward, and at the same time drives the connecting plate 505 to squeeze the airbag 503, so that the gas in the airbag 503 is blown into the first mold 401 through the air outlet pipe 506, so that the inside of the first mold 401 can be cooled down, and the connecting rod 602 drives the slider 605 to move by pushing the push plate 601, so that the side of the slider 605 with an angle is squeezed with the side of the extrusion block 8 with an angle, so that the extrusion block 8 pushes the measured product upward out of the first mold 401, which is convenient for the operator to take out the product.
