At the same time, the buffer plate and the buffer spring convert the impact force into a gentle force, which improves the molding efficiency. At the same time, it can effectively reduce the impact when the lens falls into the material receiving box to prevent the lens from being damaged or scratched due to direct impact. Moreover, by reducing the damage of the lens during the material receiving process, the yield of the lens can be significantly improved and the production cost can be reduced.
