Molded Fluorescence Plastic Lens and Manufacturing Method Thereof

A manufacturing method of a molded fluorescent plastic lens

• comprising the steps of:
• preparing a plastic preform;
• attaching fluorescent material on a preset surface area of the plastic preform;
• putting the plastic preform attached with the fluorescent material into a cavity of an upper mold core and a lower mold core of a mold;
• heating the upper mold core and the lower mold core until temperature is over the softening temperature of the plastic preform and the plastic preform becomes soft;
• then pressuring the upper mold core and the lower mold core so that the fluorescent material is inserted into surface of the plastic preform and the plastic preform is molded into a plastic lens with preset shape by the upper mold core and the lower mold core;
• cooling the upper mold core and the lower mold core, and reducing the pressure for separating the upper mold core and the lower mold core;
• and
• releasing a molded fluorescent plastic lens.

A manufacturing method of a molded fluorescent plastic lens

• comprising the steps of:
• preparing plastic material and heat the plastic material in an injection machine;
• attaching fluorescent material on a preset surface area of an upper mold and/or a lower mold of a plastic molded forming equipment;
• extruding the plastic material into a cavity of the upper mold core and the lower mold core of the plastic molded forming equipment by the injection machine;
• heating the upper mold core and the lower mold core to a preset temperature and then increasing the pressure so that the fluorescent material is inserted into surface of the plastic preform and the plastic preform is molded into a plastic lens with preset shape by the upper mold core and the lower mold core;
• cooling the upper mold core and the lower mold core, and reducing the pressure for separating the upper mold core and the lower mold core;
