- 摘要：
- A combined lens rim injection molded with soft raw material includes an upper rim and a lower rim combined together. The upper rim and the lower rim are designed to be so simple that the lens rim can easily be released from the mold through the opening. By so designing, in case of opening the mold, the upper rim and the lower rim can be automatically released from the mold by means of ejector pins or mechanical arms, able to save man power for removing the lens rim out of the mold, simplify a solid lens-rim mold and reduce cost of opening mold as well as time required for injection molding.
