In this embodiment, the side mold 6 is used to form the side surface of the shell, and the injection molding opening 611 is formed on the forming surface of the side mold 6, so that after injection molding, the injection molding opening 611 forms an injection molding fracture on the side surface of the shell, thereby changing the position of the injection molding opening 611, avoiding the injection molding fracture from being located on the front surface or the main appearance view angle of the shell, thus reducing the smoothness requirement on the injection molding fracture, reducing the process difficulty, shortening the processing period, and reducing the processing cost.

Further, a convex molding surface for processing the groove is arranged on the molding surface, and the injection molding opening 611 is positioned on the convex molding surface. The injection molding opening 611 is located on the convex surface, and after injection molding, the injection molding opening is located in the groove, so that the injection molding opening is prevented from being formed on the outer surface of the shell, and the processing standard can be reduced by the injection molding opening in the groove. Of course, after the part is installed in the groove, the part covers the injection fracture, and the injection fracture can be not treated. In this way, the processing cycle can be reduced and the production cost can be reduced.

Still further, as shown in fig. 5, the convex profile includes a first boss 62 and a second boss 63 provided on the first boss 62, and the injection molding port 611 is located at a surface abutment of the first boss 62 and the second boss 63.
