511, the quantity value of mould 6 infiltration volume triggering pressure sensor 503, this can avoid replacing mould 6 after, the infiltration quantity value is too little to appear misjudgement easily or the infiltration quantity value is too big leads to the condition emergence of detection time overlength, through above operation, can make equipment flexible adaptation different grade type mould 6, this application scope that makes equipment can obtain promoting.
In summary, when the plastic housing mold leakage detection device is used, firstly, a worker opens the sealing door 2, positions the upper and lower (left and right mold) parts of the mold 6 to be detected on the inner side of the fixing frame 501, and at this time, the worker screws the screw rod 508 to drive the clamping plate 509 to displace toward the mold 6, so that the fixing frame 501 can fix the mold 6 through the clamping of the clamping plate 509 to the mold 6, and after the mold 6 and the clamping plate 509 are fixed, the worker connects the pressurizing pipe 9 with the injection molding opening of the mold 6, and simultaneously closes the sealing door 2;
Then, the two moulds 6 can be driven to be close by the electric push rod 4 until the two moulds 6 are closed, the water inlet pipe 10 is opened after the two moulds 6 are closed, clean water can be filled into the detection box 1 until the clean water completely passes through the moulds 6, gas can be injected into the two moulds 6 by the operation of the gas delivery pump 7 after the clean water passes through the moulds 6, if the moulds 6 have leakage conditions, the gas can be exposed from leakage points of the moulds 6 and generate bubbles in water, so that the equipment can judge whether the moulds 6 have leakage by shooting whether the water surface generates bubbles through the camera 8, in addition, due to the fact that the inside of the moulds 6 is in a high-pressure gas delivery state, the gas can form more obvious bubbles from the leakage points into the water, and the probability that the camera 8 is difficult to capture clearly due to too small bubbles can be reduced;
Then after the mold 6 completes the leakage detection of the internal high-pressure gas transmission, if the camera 8 does not shoot obvious bubbles, the electric push rod 4 works to drive the two molds 6 to separate, so that the water in the detection box 1 can enter the inside of the mold 6, after the inside of the mold 6 is filled with water, the drain pipe 11 is opened, the water in the detection box 1 can be completely discharged, after the water in the detection box 1 is discharged, the high-pressure gas can be injected into the mold 6 again through the operation of the gas transmission pump 7, if the mold 6 has leakage points, the water in the mold 6 can leak from the leakage gaps due to the high-pressure state, the reset springs 505 on the upper side and the lower side of the regulating seat 507 are in a tension balance state, if the mold 6 has the condition of leakage from inside to outside, the clean water stored in the mold 6 can gradually flow out of the mold 6, at the moment, the whole weight of the mold 6 can be reduced, after the weight of the die 6 is reduced, the tension balance of the return springs 505 on the upper side and the lower side of the adjusting seat 507 is relieved, the adjusting seat 507 and the die 6 gradually move upwards along with the reset of the return springs 505 due to the weight reduction, in the process of moving upwards the adjusting seat 507, the top pressing plate 511 can be driven to synchronously move upwards, and the top pressing plate 511 can press the pressure sensor 503, by the design, a worker can judge whether the die 6 leaks outwards or not by observing whether the pressure of the pressure sensor 503 increases or not, the mode of filling the inside of the die 6 with water and pressing the water out of a leakage point by utilizing high pressure can be adopted, the phenomenon that in the preliminary bubble detection process, bubbles are not obvious due to too small leakage point, the condition that the camera 8 cannot be effectively captured, the condition of judging leakage can be caused, the detection precision of equipment can be improved, and the operation of filling water in the die 6 can be avoided, and the operation of pressurizing the inside of the mold 6 itself can be inherited to preliminary bubble detection, which enables the convenience of re-inspection of the apparatus to be greatly improved;
Finally, thanks to the way that the clamping plate 509 is clamped with the die 6 by adopting the displacement of the screw rod 508, the clamping plate 509 can adapt to dies 6 with various sizes, in addition, a worker can detach or add the reset spring 505 by unscrewing the bolts connected with the reset spring 505 inside the first connecting seat 504 and the second connecting seat 506, when equipment replaces dies 6 with different types, the force of the reset spring 505 on the upper side and the lower side of the adjusting seat 507 during tension balance can be adjusted through the operation, the extension length of the top pressing plate 511 at the outer end of the telescopic seat 510 can be adjusted by unscrewing the bolts at the outer end of the telescopic seat 510, the quantity value of the die 6 seepage triggering pressure sensor 503 can be adjusted by adjusting the extension length of the top pressing plate 511, the situation that the detection time is overlong due to the fact that the seepage judgment value is too small easily occurs after the die 6 is replaced can be avoided, the equipment can be flexibly adapted to dies 6 with different types through the operation, and the application range of the equipment can be improved.
