Summary: | The invention discloses a 3D printing forming process of a sand mold for production of a tailstock-free counterweight. The 3D printing forming process comprises the following steps that I, the sand mold for production of the tailstock-free counterweight is divided into 3-5 small sand molds for independently printing according to a three-dimensional CAD model of the sand mold for production of the tailstock-free counterweight; II, according to the three-dimensional model of the currently printed small sand molds, 3D layered printing is carried out on the current small sand molds; III, the remaining small sand molds are respectively printed and formed by adopting the printing method in the step II; IV, the printed small sand molds are spliced together to form the sand mold for production of the tailstock-free counterweight; and V, after the small sand molds are spliced to form the sand mold for production of the tailstock-free counterweight, the sand mold is put into a sand box, and resin sand is added at the p |
