为提高生产率,增加可靠性,基于TRIZ矛盾矩阵的原理,提出解决压型定型周期长问题的措施,提出了快速熔模铸造工艺路线。采用增材制造技术打印得到ABS材质铸件模样,采用常规方法制作蜡质浇注系统,试验粘接工艺和调整涂料配方,组成蜡模组,多层挂砂得到型壳,分别脱蜡、脱ABS,经过浇注、清理,获得了合格铸件。 In order to improve the productivity and increase the reliability, based on the principle of TRIZ contradictory matrix, the measures to solve the problem of the long press - shaping period are put forward and the technological route of rapid investment casting is put forward. The ABS material casting was printed by additive manufacturing technology, the wax casting system was made by the conventional method, the bonding process was tested and the coating formula was adjusted, the wax module was formed, the multi-layer sand was obtained, the dewaxing, ABS removal, After pouring, cleaning, access to qualified castings.
