[0042] The mounting base 1 is provided with two guide members 9, which are guide posts or guide sleeves 2021. The guide structure is used to cooperate with the guide structure of the mold of the airbag shell insert 40. In this embodiment, the guide member 9 is a guide post, which can cooperate with the guide sleeve of the mold 30 of the airbag shell. The relative approaching action between the guide post and the mold 30 of the airbag shell can be performed by using a robot to drive the airbag shell insert automatic embedding device, or by using the opening and closing driving device of the mold 30 of the airbag shell.

[0043] The implementation principle of the airbag shell insert automatic embedding device in this embodiment is as follows: the automatic embedding device is arranged outside the mold 30 of the airbag shell when in use. During use, the airbag shell insert 40 is installed in the positioning groove 31 of each sheet metal fixed block 3, and then the automatic embedding device is moved to the opening and closing area of the mold 30 by a movement mechanism. Then, the telescopic driving member 5 drives the movable panel 4 to move close to the fixed panel 2, so that the top rod 6 pushes the airbag shell insert 40 out of the positioning groove 31 and moves to embed the mold 30 of the airbag shell. Subsequently, the telescopic driving member 5 is reset, and the automatic embedding device exits the opening and closing area of the mold 30.
