[0002] For injection molded parts with special structures, such as Figure 1 The airbag frame shown has a fabric hanging area of ​​200. In combination... Figure 2 Before molding, the hanging cloth 200 needs to be fixed onto the mold. After injection molding, the hanging cloth 200 and the product 100 are combined into one.

[0003] The two sides of the hanging cloth 200 are bent to form a vertical side 201. Corresponding slots need to be made in the mold to squeeze the vertical side 201, thereby fixing the hanging cloth 200 to the mold.
