一种高效的充氧压铸模排气系统设计方案

充氧压铸法能有效的避免在压铸件中产生气孔等缺陷,在生产中的应用已日益广泛。在对现有模具的结构方案进行分析的基础上,设计了一种高效实用的充氧压铸模排气系统结构方案。新的设计方案改变排气的沿程阻力,不改变原有的型腔结构,达到快速置换氧气的目的,来实现效率的提高;另一方面,改变了排气通道,扩大了排气的通道,减缓了排气的速度,减弱了氧气传感器的冲击力量,降低了对氧气传感器的损坏。

Design of An Efficient Venting System of Pore-free Die Casting Mould

Pore-free die casting process can effectively avoid defects generated in the die-casting such as porosity.Application in production has become increasingly widespread.In this paper,based on the analysis of the existing mold programs structure,a practical high-performance venting system and pore-free die casting mould structure is designed.The new design changes the resistance along the exhaust way.However,it does not change the original structure of mold impression.Due to achieve the purpose of the rapid ex...
