摘要

分析了压铸件飞边产生的原因

并提出了解决问题的措施。为了减少飞边

应尽量使合模力中心与涨型力中心致;提高模具的刚度

包括适当增加模具厚度

采用不通孔模体

使用支撑钉;使用时保证分型面清洁和合适的间隙。

Abstract

The formation of the flashes in die casting processing are analysed

and the ways to reduce the flashes and improve the accuracy of diecastings are presented. To reduce the flash

it is necessary to make the center of locking force of the die casting machine in line with the center of opening force resulted from injection pressure as much as possible

to increase the rigid of the mould

including increasing the thickness of the platens appropriately

utilizing the solid enclosed bolster and supporting pillars

and to keep the parting surface clean and reasonable allowance during operation.
