Abstract

The invention relates to the technical field of sand mold casting, in particular to a 3D printing sand mold of a supercharger bearing shell and a molding method. Comprising a lower box sand mold, a middle box sand mold, an upper box sand mold, a middle box sand mold lower core head, a middle box sand mold upper core head, two lower box sand mold lifting lugs, two middle box sand mold lifting lugs, two upper box sand mold lifting lugs and three middle box sand mold process ribs, the middle box sand mold lower core head is arranged between the lower box sand mold and the middle box sand mold, the middle box sand mold upper core head is arranged between the middle box sand mold and the upper box sand mold, lower box sand mold lifting lugs are arranged on the two sides of the lower box sand mold, middle box sand mold lifting lugs are arranged on the two sides of the middle box sand mold, and upper box sand mold lifting lugs are arranged on the two sides of the upper box sand mold. By means of the structure, the production rapidness of the supercharger bearing shell is improved, and therefore the production efficiency of the supercharger bearing shell is improved.

Description

technical field [0001] The invention relates to the technical field of sand casting, in particular to a 3D printing sand mold for a supercharger bearing shell and a molding method. Background technique [0002] At present, in the production of supercharger bearing shells, the surface quality of manual molding (core) is poor, the size error is large, and there are many seams. It is time-consuming and laborious to polish the production blank. [0003] By making a wooden mold or a metal mold, pouring the raw material in the wooden mold or the metal mold, and waiting for the raw material to self-harden and form, the corresponding sand mold can be obtained. [0004] However, in the process of using wood mold or metal mold to produce supercharger bearing shell, various types and specifications of products correspond to a set of molds. Assembling, grinding, the cycle is long, and the production speed of the supercharger bearing shell is not good, thus affecting the production effi...
