Add rounded corners and increase the sealing area.

1. Add rounded corners: Adding rounded corners at right angles during design can avoid excessive stress concentration during sealing, increase the radius of the fillet, reduce stress concentration during sealing, and prevent mold Cracked or leaking rubber.

2. Increase the sealing area: At right angle corners, the sealing area can be increased, which can provide a good sealing effect, increase the contact area between the rubber and the mold, and improve the adhesion and adhesion of the rubber. Sealing performance.
