[0025] A mounting bracket 3 is fixedly connected to the base plate 1.

[0026] The pick-and-place transfer mechanism 4 includes a reinforcing frame 41, a drive motor 42, a rotating shaft 43, a rotating disk 44, an infrared emitter 45, and a test barrel 46. The reinforcing frame 41 is fixedly connected to the base plate 1. The drive motor 42 is fixedly installed on the reinforcing frame 41. The rotating shaft 43 is connected to the output shaft of the drive motor 42. The rotating disk 44 is connected to the rotating shaft 43. Two infrared emitters 45 are installed on the rotating disk 44. Two test barrels 46 are fixedly connected to the rotating disk 44. The test barrels 46 are used to carry the injection molding barrels.

[0027] The support mechanism 5 includes a telescopic rod 51, a first electric push rod 52, a first connecting slide rod 53, a support top plate 54, and a first distance sensor 55. Two telescopic rods 51 are fixedly connected to the base plate 1. Multiple first electric push rods 52 are fixedly installed on the base plate 1. The first electric push rods 52 are connected to the telescopic rods of the first electric push rods 52. The support top plate 54 is connected between the top ends of the multiple first connecting slide rods 53. The support top plate 54 is used to support the rotating disk 44. The first distance sensor 55 is installed on the support top plate 54.

[0028] The sealing performance testing mechanism 6 includes a reinforcing support frame 61, an infrared receiver 62, a second electric push rod 63, a second connecting slide rod 64, a detection plate 65, a differential pressure tester 66, a connecting pipe 67, and a second distance sensor 68. The reinforcing support frame 61 is fixedly connected to the base plate 1. The infrared receiver 62 is installed on the reinforcing support frame 61 and cooperates with the infrared transmitter 45. The second electric push rod 63 is fixedly installed on the reinforcing support frame 61. The bottom end of the telescopic rod of the second electric push rod 63 is connected to the second connecting slide rod 64. The bottom end of the second connecting slide rod 64 is connected to the detection plate 65. The differential pressure tester 66 is fixedly installed on the reinforcing support frame 61. The differential pressure tester 66 is used to test the sealing performance of the injection molding barrel. A connecting pipe 67 connects the differential pressure tester 66 and the detection plate 65. The second distance sensor 68 is installed on the detection plate 65.

[0029] Anti-slip pads are provided on the top support plate 54.

[0030] The working principle of this utility model is as follows: the first distance sensor is provided with a first threshold and a second threshold, and the value of the first threshold is greater than the value of the second threshold.

[0031] The second distance sensor is equipped with a first threshold and a second threshold, wherein the value of the first threshold is greater than the value of the second threshold.

[0032] After sealing the injection molding barrel, it is placed into the test barrel. The start button is then pressed, controlling the drive motor to rotate the shaft, rotating disk, infrared transmitter, and test barrel. When the infrared transmitter aligns with the infrared receiver, the receiver receives the signal, stopping the drive motor. Simultaneously, the first electric push rod raises the first connecting slide rod, support plate, and first distance sensor, extending the telescopic rod. When the distance between the first distance sensor and the base plate reaches a preset first threshold, the first electric push rod stops, and the second electric push rod starts. At this point, the support plate presses against the rotating disk, increasing its stability and preventing the rotating disk from... If a break occurs during the testing process, the second electric push rod will cause the second connecting slide rod, the detection plate, and the second distance sensor to descend. When the distance between the second distance sensor and the reinforcing support frame reaches the first preset threshold of the second distance sensor, the second electric push rod will stop working. At the same time, the differential pressure tester will be controlled to work. The detection plate will seal the test barrel. The differential pressure tester will generate suction, and the gas inside the test barrel will be slowly extracted, creating a negative pressure inside the test barrel. When the sealing performance of the injection molding barrel is poor, the gas will be extracted at a faster rate. However, when the injection molding barrel is completely sealed, the gas inside the test barrel will not be extracted after the gas inside the barrel is extracted. Therefore, the sealing performance of the injection molding barrel can be measured. At this time, the timer will count the testing time, thereby saving the time required for testing the injection molding barrel.

[0033] After the injection barrel test is completed, the second electric push rod drives the second connecting slide rod, the detection plate, and the second distance sensor to rise. When the distance between the second distance sensor and the reinforcing support frame reaches the second threshold preset by the second distance sensor, the second electric push rod is stopped. At the same time, the first electric push rod is controlled to drive the first connecting slide rod, the support top plate, and the first distance sensor to descend, and the telescopic rod is shortened. When the distance between the first distance sensor and the bottom plate reaches the second threshold preset by the first distance sensor, the first electric push rod is stopped. At the same time, the drive motor is controlled to drive the rotating shaft, the rotating disk, the infrared emitter, and the test barrel to rotate in the opposite direction to reset. Then, the injection barrel in the test barrel can be removed. If you want to test again, repeat the above operation.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
