[0030] The working principle is as follows: when the product is being formed, the molding material is injected into the mold 1, and the pumping device 3 works to remove the excess gas inside the mold; specifically, the docking box 4 is fixed to the side of the mold 1, that is, the buckle part 902 is buckled with the docking buckle 104 to complete the fixation. When it needs to be removed and replaced, it can be quickly replaced, that is, the electromagnetic slide bar 6 controls the push part 601 to slide, and the push part 601 pushes the release part 901, and then the buckle rod 9 moves, that is, the buckle part 902 is released from the docking buckle 104 to achieve release; further, when docking, the docking cone 7 is docked with the air hole 102, and the sealing ring 103 plays a sealing role. The docking cone 7 is a truncated cone, which can be tightly squeezed on the sealing ring 103, and the spring 8 provides extrusion elastic force to achieve complete sealing; the air pressure inside the docking box 4 can be detected by the air pressure detector 5. If the sealing of the connection is not good, the air pressure inside the docking box 4 will change accordingly. The air pressure detector 5 monitors in real time and can perform maintenance operations in time.

[0031] The docking box 4 works, and the gas is transmitted through the pumping pipe 21. During daily maintenance, the screw motor 11 works, the screw 12 rotates, and the screw slide 13 slides. The position electric cylinder 14 controls the position of the docking transfer cylinder 15, and the position electric cylinder 2 17 synchronously adjusts the position of the docking transfer cylinder 15, so that the docking transfer cylinder 15 cooperates with the transfer docking column 401, and the electromagnetic fixing rod 16 cooperates with the fixing hole on the transfer docking column 401 to fix the docking box 4. When the docking box 4 and the mold 1 are released from fixation, the docking box 4 is transferred and transferred to the relative position of the processing mechanism, so that the docking cone cylinder 7 cooperates with the cleaning cylinder 27, and the cleaning cylinder 27 is controlled to rotate by the processing motor 26 to maintain and clean the docking cone cylinder 7. The operator can add cleaning liquid to the cleaning cylinder 27 to remove the residual impurities attached to the docking cone cylinder 7.

[0032] Furthermore, when the air tightness test is performed on the pumping tube 21, the docking box 4 is controlled to move, that is, to extend outward. At this time, the pumping tube 21 extends following the movement of the docking box 4. The traction motor 22 controls the limit wheel 23 to limit and pull the pumping tube 21. The circumferential area of ​​the pumping tube 21 continuously passes through the inside of the detection box 20. The pumping device 3 works, so that the docking cone 7 is in a suction state, that is, air passes through the pumping tube 21. The detection drive motor 18 works, and under the gear transmission, the connecting gear 29 rotates. Under the action of the linkage belt structure 28, each rotating drum 3001 rotates, and the airflow detector 30 can detect the airflow change. If the pumping tube 21 has poor sealing, it can be detected by the airflow detector 30. As the pumping tube 21 extends, combined with the rotation of the rotating drum 3001, the entire area of ​​the pumping tube 21 can be detected.
