[0052] The nut feeding mechanism 3 includes a nut feeding component, a nut ejecting component, a nut gripping component, and a nut moving component 38; the nut feeding component is used to move the nuts to the nut ejecting component; the nut ejecting component is used to eject the nuts; the nut gripping component is used to pick up and place the nuts; the nut moving component 38 is used to drive the nut gripping component to move between the mold 12 and the nut ejecting component;

[0053] The discharging mechanism 5 is used to drive the finished products to be discharged after passing through the inspection mechanism 4.

[0054] Specifically, for the injection molding automatic feeding, inspection and discharging machine in this embodiment, first, the mold 12 is opened, the flat pin feeding component moves the flat pins into the flat pin ejecting component, the flat pin ejecting component ejects the flat pins, and then after the flat pin moving component 274 drives the flat pin picking and placing component to move above the flat pin ejecting component, the flat pin picking and placing component grabs the ejected flat pins, and then the flat pin moving component 274 moves the flat pin picking and placing component to the mold 12, so as to place the flat pins on the mold 12, thus completing the feeding of the nuts;

[0055] Then the nut feeding component moves the nuts into the nut ejecting component, the nut ejecting component ejects the nuts, and then after the nut moving component 38 drives the nut gripping component to move above the nut ejecting component, the nut gripping component grabs the ejected nuts, and then the nut moving component 38 moves the nut gripping component to the mold 12, so as to insert the nuts into the flat pins on the mold 12, thus completing the feeding of the nuts;

[0056] Then the mold 12 is closed to start injection molding.

During the process of the clamping seat 21 descending close to the flat pin, the flat pin presses the movable clamping block 24 to overcome the elastic force of the resetting member 221, causing the movable clamping block 24 to move away from the fixed clamping block 23, so that the flat pin enters between the fixed clamping block 23 and the movable clamping block 24. Due to the action of the elastic force of the resetting member 221, the flat pin is fixed between the fixed clamping block 23 and the movable clamping block 24. When the flat pin needs to be taken out, the ejecting component is activated to eject the flat pin from between the fixed clamping block 23 and the movable clamping block 24, and cooperate with the flat pin moving component 274 to realize the automation of flat pin picking and placing.
