[0022] The working principle of the above technical solution is as follows: when in use, the user installs the equipment at the use position through the mounting parts 14 and bolts, and then when demolding is required, the operator matches the bracket 2 and the suction cup 7 with the injection mold, and then the pneumatic telescopic column 11 is extended to make the suction cup 7 correspond to the top of the mold groove, and then the vortex air pump 8 is started to extract the gas inside the guide tube 10 and the vertical connecting tube 20, and the gas in the horizontal connecting tube 25 and the rectangular tube 18 is extracted through the vertical connecting tube 20, and the gas inside the suction tube 6 is extracted through the corrugated telescopic tube 5. At this time, the suction cup 7 is located at the top of the injection molded part, and the air flow enters from the suction cup 7 and the inside of the injection molded part, applying a suction force to the injection molded part. At this time, the injection molded part fits in the position of the silicone cone 17 and the limiting suction hole 24 under the action of air pressure adsorption. After the injection molded part is adsorbed, the pneumatic telescopic column 21 is extended, and The cylindrical blocking piston 22 is pushed out, so that the cylindrical blocking piston 22 blocks the position of the guide tube 10, and negative pressure is formed inside the guide tube 10, the vertical connecting tube 20, the horizontal connecting tube 25, the rectangular tube 18 and the corrugated telescopic tube 5 and the suction tube 6. Then the pneumatic telescopic column 11 retracts, and the servo motor 15 rotates to drive the screw 13 to rotate, thereby applying a spiral transmission force to the movable mounting seat 16 through the screw 13. The movable mounting seat 16 moves to the collection position under the limiting action of the slide rod 12, and then the pneumatic telescopic column 21 retracts so that the cylindrical blocking piston 22 contacts the limiting blockage of the guide tube 10.

[0023] In another embodiment, Figure 1-Figure 6 As shown, the inner wall of the silicone cone 17 is conical, and the taper of the silicone cone 17 is greater than the taper of the suction cup 7.

[0024] By means of the silicone cone 17 and the limiting suction hole 24, the soft structure of the suction cup 7 can be contact-sealed with the injection mold. When the air pressure sucks up the plastic fastener, the soft structure of the silicone cone 17 is deformed, and the injection molded part can be clamped in cooperation with the limiting suction hole 24. The hollow metal mesh 23 is responsible for blocking the plastic fastener from penetrating deeper, and the larger-sized plastic fastener is blocked at the bottom of the limiting suction hole 24, thereby achieving adsorption. Therefore, it can adapt to plastic fasteners of more sizes and more models, and is convenient for increasing the unloading operation of plastic fasteners of different sizes under a certain size.

[0025] In another embodiment, Figure 1-Figure 4 As shown, the top end of the adjusting bolt 19 contacts the bottom of the fixing plate 4 .

[0028] The multiple settings of the suction tube 6 and the corrugated expansion tube 5 facilitate the adsorption of plastic fasteners corresponding to multiple injection molds, and the rectangular tube 18 and the horizontal connecting tube 25 cooperate to connect with the top of each corrugated expansion tube 5, so as to facilitate the airflow to be gathered to the vertical connecting tube 20, and air is sucked through the guide tube 10 and the vertical connecting tube 20, which is convenient for coordinated operation and airflow conduction.

[0029] In another embodiment, Figure 1-Figure 5 As shown, the fixed tube 9 and the vortex air pump 8 are both fixedly installed on the top of the support plate 1, the size of the fixed tube 9 is larger than that of the guide tube 10, the specifications and dimensions of the cylindrical blocking piston 22 are compatible with the specifications and dimensions of the guide tube 10, and the tube wall of the guide tube 10 located inside the fixed tube 9 is provided with a groove compatible with the cylindrical blocking piston 22.

[0030] After the injection molded part is adsorbed, the pneumatic telescopic column 21 is extended, and the cylindrical blocking piston 22 is pushed out, so that the cylindrical blocking piston 22 blocks the position of the guide tube 10, which is convenient for sealing the inside of the guide tube 10. The fixed tube 9 is larger than the guide tube 10 and is sleeved on the outside of the guide tube 10. The cylindrical blocking piston 22 passes through the tube wall of the guide tube 10 on one side of the fixed tube 9 to open a groove, so as to block the guide tube 10, which is convenient for coordinated operation and blocking.

[0031] In another embodiment, Figure 1-Figure 3 As shown, two ends of the slide bar 12 are fixedly mounted on opposite sides of the mounting member 14 , and the servo motor 15 is fixedly mounted on the outside of the mounting member 14 .
