摘要

传统的低压铸造方法存在效率低、无法连续生产、金属液品质及气压加压压力波动大的缺陷

为此开发出一种基于PLC和触摸屏技术的新型连续式低压铸造技术。该技术将现有传统的低压浇注兼保温坩埚分成3个独立的坩埚即保温坩埚、加压坩埚、浇注坩埚

3个坩埚底部由过道连通

分别完成加、补料、液面加压及升液浇注3个主要动作。加压坩埚具有定量功能

每次浇注前液面均保持在恒定高度

加压时升液曲线稳定、精确

重复性高。保温坩埚实现了外部补料与加压浇注互不干涉

保证了生产的连续性

生产效率显著提高。

Abstract

A novel continual low pressure die casting technology based on PLC and touch screen was developed due to some disadvantages occurred in the traditional low pressure die casting process

such as low efficiency

poor liquid quality and unstable air pressure. The new equipment is made up of three independent furnaces including holding furnace

pressurizing furnace and up-stream furnace. The three furnaces are connected by the paths located in the bottom of the furnace. Refilling

pressurizing

pouring are fulfilled by the three furnaces

respectively. Pressurizing furnace possesses constant liquid volume and liquid level is kept at the same height before air pressurizing. So the air pressure curve is accurate and stable

and good reproducibility can be achieved for each pouring. Interruption between refilling and pouring through holding furnace can′t observed. Therefore continual production and high efficiency can be guaranteed.
