[0028] Among the existing plastic products, there are various types and structures. Bushing inserts and magnetic rings are often required to be added during the injection molding process of plastic products. After the injection molding is completed, the plastic products need to be inspected to detect whether the bushing inserts and magnetic rings are missing. The conventional detection method is mainly through manual observation, but manual observation is often prone to missed detection, and the detection efficiency is low, which increases the detection cost.
[0029] Based on this, an embodiment of the utility model provides a leakage prevention detection mechanism, which is provided with a first magnetic core sensor, a second magnetic core sensor, a bushing sensor and a leakage prevention detection console.

[0030] Therefore, the embodiments of the present invention are further described below in conjunction with the accompanying drawings.
[0031] Reference Figure 1 and Figure 2 As shown, Figure 1 It is an overall structural diagram of the anti-leakage detection mechanism provided by the embodiment of the utility model.

The metal sensor 150 is communicatively connected to the leakage detection console 140. The metal sensor 150 is close to the first magnetic core sensor 110, the second magnetic core sensor 120 and the bushing sensor 130 at the same time. The metal sensor 150 is located on one side of the leakage detection console 140, and can effectively detect the relevant positions of the magnetic ring and the bushing insert through the metal sensor 150, thereby improving the accuracy of detection and avoiding missed detection.
[0034] In addition, the anti-leakage detection console 140 also includes a PLC controller 141 for controlling the operation of the anti-leakage detection mechanism. The PLC controller 141 is respectively communicated with the first magnetic core sensor 110, the second magnetic core sensor 120, the bushing sensor 130 and the metal sensor 150. The PLC controller 141 is arranged inside the shell of the anti-leakage detection console 140. Thus, the anti-leakage detection mechanism can be precisely controlled.
[0035] At the same time, the leakage detection console 140 also includes a control switch 142, which is used to start, reset or shut down the operation of the leakage detection mechanism. The control switch 142 is arranged outside the shell of the leakage detection console 140, and the control switch 142 is communicatively connected to the PLC controller 141.
[0036] Furthermore, the leak-proof detection console 140 includes a good product indicator light 143, which is used to display the good product detection results of the plastic product to be tested.

[0041] Further, the working principle of the above-mentioned leakage prevention detection mechanism is explained as follows:
[0042] First, turn on the control switch 142, and the power supply 145 outputs a 24V voltage to the PLC controller 141 for power supply. The leakage detection mechanism resets itself based on the control switch 142, and then the good product indicator light 143 flashes for 1 second and then goes out. The plastic product is placed close to the first magnetic core sensor 110, the second magnetic core sensor 120, the bushing sensor 130 and the metal sensor 150, and the magnetic ring and bushing insert on the product are detected. Then the first magnetic core sensor 110, the second magnetic core sensor 120, the bushing sensor 130 and the metal sensor 150 transmit the feedback signal to the PLC controller 141. Then, when the PLC controller 141 receives the feedback signal as a signal after sensing the magnetic ring and the bushing insert within 1.5 seconds, the PLC controller 141 outputs a good product signal to the good product indicator light 143, and the good product indicator light 143 flashes; when the PLC controller 141 receives the feedback signal as a signal after not sensing the magnetic ring and the bushing insert within 1.5 seconds, the PLC controller 141 outputs a bad signal to the bad indicator light 144 and the buzzer alarm, and the bad indicator light 144 flashes and the buzzer alarm sounds. Finally, the plastic product is taken out of the detection range, and the leakage detection mechanism is self-reset based on the control switch 142.
