Study On The CAD System Of Glass Bottle Mould

This paper analyses and compares the present status of glass bottle mould design of domestic and foreign situation. Based on the analyses of forming process and manufacturing engineering of glass bottle, a CAD(Computer Aided Design) system of glass bottle mould-GBMCAD(Glass Bottle Mould CAD) is developed. In this paper, the studies of the design methods of GBMCAD system and the methods of data management in the mould CAD and the automation design of glass bottle mould and the automation output of mould schedule drawing are the emphases.The GBMCAD system developed by using Visual C++ and ObjectARX requires operating system of Windows98 or Windows2000. It actualizes the automation design of glass bottle and mould and automation output of the mould schedule drawing. In this system, the thinking of Object Oriented Programming is applied. The main functions of GBMCAD system are as follows: (1)Automation design of glass bottle. In this part, the planar and three-dimensional drawing of designed glass bottle can be shown. (2)Automation design of glass bottle mould. It includes the choice of standard moulds and the calculation of none-standard moulds. (3)Automation output of the mould schedule drawing. In this part, the thinking of parameterized drawing is used. The system can draw the mould schedule drawing with the data produced in mould design process automatically. (4)Drawing library. It includes glass bottle library and standard mould library.
