The invention provides a hanging structure and hanging method of a 3D printing sand core. The hanging method is implemented through the hanging structure, and comprises the following steps of in the design process of the 3D printing sand core, a lifting hole groove is reserved in the sand core, wherein the lifting hole groove is located at the middle upper part of the sand core, and the opening ofthe lifting hole groove is located on the upper surface of the sand core; the lifting hole groove is composed of a lifting appliance loading hole and a lifting appliance supporting groove, the lifting appliance loading hole extends into the sand core, and the lifting appliance supporting groove is out of position with the lifting appliance loading hole but communicates with the tail end of the lifting appliance loading hole; and the lifting hole groove is matched with a lifting appliance, wherein the lifting appliance enters the lifting hole groove from the lifting appliance loading hole andthen is clamped and fixed through the lifting appliance supporting groove, and finally the sand core is lifted through lifting the lifting appliance by external lifting equipment. According to the hanging structure and hanging method of the 3D printing sand core, the problem that a sand core lifting structure cannot be pre-buried in the lifting process of a large-sized 3D printing sand core can beeffectively solved, the lifting hole groove is matched with the the lifting appliance, the lifting process is safe and stable, lifting is convenient, and popularization and utilization can be facilitated.
本发明提供了一种3D打印砂芯吊挂结构及吊挂方法,该吊挂方法通过吊挂结构实施,过程为:在3D打印砂芯设计过程中,在砂芯的内部预留出吊运孔槽,吊运孔槽位于砂芯的中上部且吊运孔槽的开口位于砂芯上表面;吊运孔槽由吊具装入孔以及吊具支撑槽组成,吊具装入孔伸入砂芯内部,吊具支撑槽与吊具装入孔异位但于吊具装入孔末端连通;吊运孔槽与吊具配做,吊具由吊具装入孔进入吊运孔槽,然后通过吊具支撑槽装卡固定,最后通过外部吊运装备吊运吊具实现对砂芯的吊运。本发明有效解决了大型3D打印砂芯在吊运过程中,砂芯吊运结构无法预埋的问题,采用吊运孔槽和吊具的配合,吊运过程安全平稳,吊运方便,便于推广利用。
