[0028] In practical use, the molding die for a quick-assembly carbon fiber wheel rim according to an embodiment of this application is as follows: First, the carbon fiber fabric used for forming the banner is placed on the lower banner forming mold 206. The lower forming hydraulic cylinder 202 drives the lower banner forming mold 206 to move upward. With the cooperation of the upper banner forming mold 209 and the lower banner forming mold 206, the carbon fiber fabric is inflated into a rod-shaped banner by inflating the air bladders that are pre-placed in the carbon fiber fabric. After the banner is formed, the lower forming hydraulic cylinder 202 drives the lower banner forming mold 206 to move downward. Then, the carbon fiber fabric with air bladders inside is placed on the lower hub forming mold 207, and at the same time, the end of the banner closest to the hub extends into the hub. The lower spoke forming mold 206 continues to move downward to the bottom of the worktable 101. The upper forming hydraulic cylinder 201 drives the upper mold 204 to move downward, so that the upper hub forming mold 208 and the lower hub forming mold 207 cooperate. At this time, the upper spoke forming mold 209 extends into the round hole on the worktable 101. By inflating the airbag set in the carbon fiber cloth, the carbon fiber cloth expands.
