[Abstract]:Optical glass molding technology is a kind of precision copy molding technology. Compared with the traditional processing technology, such as polishing and grinding, it has the advantages of one-off molding, high efficiency and low cost, suitable for mass production and so on. With the increasing use of high-precision optical glass lenses, this technology has been developed rapidly. This technology is relatively backward in China, and the glass molding equipment used in China basically depends on imports. In order to adapt to the rapid increase in the use of high-precision glass lenses in China, it is urgent for our country to master the molding technology of glass. Development of independent property rights of glass molding equipment. This project is based on the Shenzhen-Hong Kong innovation circle project (the research and development of micro-nano-printing device and processing technology of precision glass optical microstructure) to research and development of glass moulding equipment. Glass molding equipment is divided into four parts: structure, heating system, mold, control system. In the design of the equipment, the four parts will be developed by four graduate students. In this paper, the structure of high precision optical glass molding machine is designed. The main contents are as follows: (1) according to the working principle, the transmission structure of glass mould press is designed, three transmission schemes are designed, and the advantages and disadvantages of each scheme are compared. Finally determine the most suitable scheme as the transmission scheme of the equipment. The equipment has high precision of die closing, and several schemes are designed for precision assurance in structural design. The main methods are classified precision control and centering device to ensure die closing. That is to say, the upper and lower mold coaxiality is first controlled in the error range of centering device by the structure, and the upper mold position is adjusted by the centering device when the die is closed. The guide post of die can be safely closed by chamfering. (3) according to the dimensions, installation position and installation mode of transmission parts and other parts, the frame of this equipment is made of square steel welded. After the design of the frame structure is finished, the static simulation is carried out with ANSYS Workbench, and the structure of the frame structure is determined by improving the position of the stress concentration. Then the modal analysis of the frame is carried out, the vibration characteristic of the frame is checked, and the scheme of preventing the vibration of the frame is put forward. The other structures of the equipment are designed. The design of the components on the intermediate shaft is mainly introduced. Intermediate shaft structure is the core structure of the equipment, die, transmission, heating system are installed in the corresponding position on the shaft. The main contents are as follows: the mechanical analysis of the parts with large force, the structural design of the water-cooled block, the sealing principle of the sealing position and the installation position of the sealing ring. The motion scheme of heating cover is designed, and the machine appearance sheet metal is designed by using rodless cylinder to drive the heating cover up and down, and the final assembly is completed.
