AI Technical Summary
In existing lens molds, the lower end of the module is held between the mold frame by a spring reset. Long-term and frequent use reduces the elasticity of the spring, affecting the injection and demolding effect of the lens mold.
A hydraulic column is used to drive the lens mold to close or separate. Combined with an electric guide rail and an electric push rod to drive the demolding suction plate, automatic demolding is achieved through silicone protective pads and suction holes. A vacuum pump is used to generate negative pressure to adsorb the lens, ensuring that the lens is under force balance during the demolding process.
It enables automated demolding of lenses, preventing lens deformation and damage, and improving the production quality and efficiency of lens processing molds.
