【摘要】 本论文分析了国内外注塑模计算机辅助设计的现况，立足于国内厂家的实际设计需求，以聚合物熔体的流动行为为理论基础，开发了注塑模浇注系统CAD应用程序FSCAD。 FSCAD系统是用VC++6.0与ObjectARX相结合开发应用程序界面、编制程序代码，充分利用VC++6.0丰富的MFC类库和AutoCAD2000的图形库，在VC++6.0环境下编译成功后的应用程序加载到AutoCAD2000平台上运行。同时，还应用ODBC技术，实现了与外部数据库的有效连接。该应用程序的主要功能如下： ①最佳型腔数的优化求算，还可依据不同的实际生产条件，选择最符合实际要求的型腔求算方法，并求算浇注系统的尺寸； ②文件资料的查询实现，用ODBC技术做接口，直接访问和调用外部数据库Access2000中的储存资料； ③依据不同的输入参数，驱动绘图程序，完成参数化绘图； ④浇注系统设计中的部分图形采用位图显示，选择不同的形式，可以直观地显示相对应的图形，指导设计人员的工作。更多还原

【Abstract】 In this thesis we analyzed the present situation of Computer Aided Design of Injection Molding both in China and overseas. In order to meet the requirements of Chinese plants in practice, We developed the FSCAD of the feed system based on the theory of the flowing behavior of plastic melt.The interface and program codes of FSCAD were made by using the interaction of VC++6.0 and ObjectARX. The abundant MFC databases of VC++6.0 and database classes of AutoCAD 2000 were fully utilized. The debugged program can be run on the AutoCAD platform. Meanwhile,ODBC technology was also employed in order to reach the efficient link with outer database. The fundamental functions of FSCAD are as follows:First, calculation of the optimal cavities was achieved. Depended on the different practical situation, the certain cavity value can be gotten through the desirable calculated method and the values of different injection parts can be determined. Second, using ODBC as an interface, the application program can visit and use the data of outer database conveniently. Third, the inputted parameters can drive the drawing program to accomplish the drawing of feed system. Fourth, the related styles of the cavity layout can be unfolded to the user directly by means of bitmaps and therefore can offer the assistance to the designer.更多还原
