The working principle of the invention is as follows:

1. the inserts (aluminum parts) are conveyed to a discharging station through a parallel vibration disc 21 of the feeding mechanism 2, the inserts 10 on the discharging station are ejected out, meanwhile, the manipulator drives the clamping mechanism 5 to reach the upper part of the discharging station, a clamping jaw mechanism 55 of the clamping mechanism 5 clamps the inserts 10, and the inserts 10 are moved to a detection station through the manipulator and placed on the detection mechanism 3.

2. The insert 10 is just sleeved on the detection head 34, the rotary pressing cylinder 32 in the detection mechanism 3 acts to drive the pressing plate 321 to rotate above the detection station and press the insert 10 downwards, if the sizes of the inner hole and the outer surface of the insert 10 meet the requirements, the insert 10 and the detection head 34 can penetrate through the guide hole 311 of the detection seat 31 to move downwards, and then the ejection plate 35 is driven to compress the ejection spring 36 downwards; if the sizes of the inner hole and the outer surface of the insert 10 are not satisfactory, the insert 10 and the detection head 34 are clamped in the guide hole 311 of the detection seat 31 and cannot move downwards; when the insert 10 is unqualified, the insert clamping mechanism 5 clamps the unqualified insert 10 to an unqualified insert collecting position, returns to the discharging station again, clamps one insert 10 again, and repeats the actions of the steps 1 and 2. And when the insert 10 is qualified, clamping the insert, and then detecting and judging the next insert 10.

3. When the two inserts 10 are qualified, the manipulator drives the clamping mechanism 5 to move the inserts 10 into the injection molding machine, after the injection molding is finished, the injection molding machine opens the mold, the clamping mechanism 5 moves between a movable mold and a static mold, and a clamping seat plate 51 and a swinging plate 52 of the clamping mechanism 5 are closed (as shown in fig. 7); because the clamping jaw mechanism 55 is provided with the ejector plate 553, when the insert 10 is clamped, the ejector plate 553 can be upwards jacked and the ejector spring 555 is compressed, when the clamping mechanism 5 moves to the injection molding machine, the manipulator drives the clamping mechanism 5 to place two inserts 10 at the hole openings of the movable mold, the clamping jaw cylinder 552 drives the clamping jaws 551 to loosen the inserts 10, the ejector plate 553 is driven under the reset force action of the ejector spring 555 to push the inserts 10 into the hole openings of the movable mold, then, the manipulator drives the clamping mechanism 5 to be close to the stationary mold, and the two material clamping mechanisms 56 on the swing plate 52 take out the injection molding parts in the mold.

4. The manipulator drives the clamping mechanism 5 to move to the position of the cutting mechanism 4, the clamping cylinder 53 of the clamping mechanism 5 extends out, the swing plate 52 is driven to open (as shown in fig. 6), the injection molded part is placed on the cutting mechanism 4, the manipulator drives the clamping mechanism 5 to withdraw from the cutting mechanism 4, the cutting cylinder 42 of the cutting mechanism 4 drives the cutting sliding plate 44 to move downwards, the cutting pressure rod 46 is enabled to press the injection molded part, meanwhile, the cutting knife 451 of the cutting knife 45 cuts off the stub bar, and in the process that the cutting cylinder 42 drives the cutting sliding plate 44 to return upwards, the drag hook 452 of the cutting knife 45 breaks off the stub bar which is not completely cut off, so that the stub bar can be completely separated from the injection molded part.

5. The manipulator drives the clamping mechanism 5 again to move to the cutting mechanism 4, and the injection molded part with the cut stub bar is taken out and placed at a collecting position.

The above description is only a preferred embodiment of the present invention, and therefore should not be taken as limiting the scope of the invention, which is defined by the appended claims and their equivalents and modifications within the scope of the description.
