A plurality of suction ports 7 are formed on the inner top wall of the injection molding part suction cup 3. A diversion groove 8 is formed on the inner bottom wall of the injection molding part suction cup 3 at the bottom of the suction port 7. The bottom of the diversion groove 8 extends into the inside of the air vent groove 5. The air vent groove 5 extends to the side wall of the injection molding part suction cup 3. A one-way valve 6 is fixedly connected to the side wall of the injection molding part suction cup 3 where the air vent groove 5 is located.

[0028] A cavity is formed on the inner bottom wall of the injection molding part suction cup 3 where the air vent groove is located.

[0030] During use, by connecting an air pump inside the base 1, flexible pneumatic operation can be performed on the injection molding part suction cup 3. When the air pump sucks air, the gas can flow into the inside of the ventilation groove 5 through the adsorption port 7 and the diversion groove 8.
