摘　　要：文中对当前国内喇叭天线板的主要生产工艺进行了介绍,指出该生产工艺的缺点,提出了采用新的精密压铸工艺批量生产该类零件的方法。以某双脊喇叭天线板作为铸件原型,设计了一套压铸模具,从原材料选择、零件结构分析、铸造工艺设计、模具结构设计等方面对压铸模具的设计要点进行了阐述,并基于FLOW-3D仿真模拟软件对模具进行了设计优化。制定工艺参数生产试铸样件,根据其表面和内部的缺陷对压铸模具进行微调优化,并对该零件的后处理方法进行了描述。最后对装配好的喇叭天线板进行了环境适应性试验和电气性能测试,验证了新工艺的有效性和模具设计的合理性。文中工作有助于喇叭天线板的工艺创新和类似薄壁铝件的压铸模具设计。This paper introduces the main production process of the domestic horn antenna plate,points out the shortcomings of the production process and puts forward the method of batch-producing this kind of parts by using a new precision die-casting process.Taking a double ridge horn antenna plate as the casting prototype,a set of die-casting mold is designed.The key points of the die-casting mold design are described in terms of raw materials selection,parts structure analysis,casting process design and mold structure design.And the mold is optimized based on FLOW-3D simulation software.Process parameters are set up to produce trial casting samples and the die-casting mold is fine-tuned and optimized according to its surface and internal defects.The post-processing method of the parts is described.Finally,the tests of environmental adaptability and electrical properties for the assembled horn antenna plate are carried out,which verifies the effectiveness of the new process and the rationality of the mold design.The work in this paper contributes to the process innovation of the horn antenna plate and the design of the die-casting mold for similar thin-walled aluminum parts.
