[Prior Art] With the development of technology, the use of electronic devices such as mobile phones has become increasingly widespread. At the same time, it is becoming lighter, more beautiful and more versatile. Its t' camera has been added to the newly developed portable electronic device in recent years. With digital phase materials, the phone is ready to shoot and easy to use, so it is getting more and more popular among users. Since the size of the mobile phone is small, the camera module mounted therein needs to have a small volume. While people are pursuing miniaturization of digital camera modules for mobile phones, 'the imaging quality is also higher. The imaging quality of objects depends largely on the advantages and disadvantages of optical lenses in camera modules. The quality and precision of the lens is highly dependent on the precision of the molding die. At present, optical lenses are mainly manufactured by two methods of compression molding and injection molding. Conventional press molding technology is mainly used to manufacture optical lenses with a diameter of 1 mm or more (see "Quartz Glass Molding by Precision Glass Molding Method", Trans· ΙΕΕ
