摘要
介绍了双臂立柱的铸件结构,为解决原采用传统木模铸造工艺生产时出现的问题,改用3D打印无模铸造方法,提出了一种双臂立柱类产品的3D打印组芯的工艺思路,设计了一种双臂立柱类铸件的3D打印生产工艺。生产结果显示:采用该工艺,无需制作模具,简化了操作过程,降低了生产难度,生产效率达到原来的2倍,并且有效改善了铸件质量,且质量稳定,解决了双臂立柱类铸件在传统铸造过程中操作难、质量容易波动的问题,铸件的废品率由原来的24.3%降至3.4%。
The casting structure of the two-armed column was introduced. In order to solve the problems in the traditional wood mold casting process,a 3D printing containerless casting method was adopted. A craft idea by designed a kind of twoarmed column pillar casting 3D printing group core process was devised. Production results showed that：by using this process without making mold,the operation process was simplified. The production difficulty was reduced. The production efficiency reached 2 times than original one. And the quality of castings was effectively improved and that remained stable. It solved the problem that the two-armed column casting was difficult to operate in the traditional casting process and the quality was fluctuate regularly. The rejection rate of the casting was reduced from 24.3% to 3.4%.
