摘要

研究了固定夹的生产工艺过程

提出了模具温度对固定夹凝固结晶的影响;给出了固定夹工艺参数的控制结果。认为挤压铸造工艺替代低压铸造或重力铸造工艺生产固定夹

不论在产品品质还是在生产效率方面都具有明显优势。生产固定夹模具工作温度控制在180

60℃的范围最为理想;当充型速度从145mm/s降至70mm/s

在同样T6热处理后

铸件表面气泡率小于5%。

Abstract

By analyzing product process of aluminum alloy fixed clamp by squeezing casting

effects of mould temperature on solidification structure of the fixed clamp were described

and processing parameters were presented.There exist some priority in quality and efficiency for producing aluminum alloy fixed clamp by squeezing casting instead of low pressure casting or permanent mold casting.The satisfied mould working temperature for producing fixed clamp is 180

60℃.When filling rate is decreased form 145mm/s to 70mm/s

the surface bubble rate in the fixed clamp is lower than 5% after T6 heat treatment.
