Abstract

The invention relates to a 78A0406M valve body and a processing technology thereof. A precoated sand shell making technology is adopted to produce a pouring mold, and thus the size accuracy of a runner is ensured; a sand core is placed in the pouring mold to be assembled, and thus assembly and positioning accuracy of the sand core are ensured; and exhaust vents of the sand core are completely guided out through steel wires, the steel wires are pulled out after a base model is produced, smoothness of air vents is guaranteed, meanwhile, the sand core strength is enhanced through steel wire liners, stable molding of the sand core is ensured, and the sand core is not prone to deforming and fracturing.

Description

technical field [0001] The invention relates to the field of valve body casting, in particular to a 78A0406M valve body and its processing technology. Background technique [0002] The internal flow of the multi-way valve body is complicated, the assembly of the sand core is relatively complicated, it is not easy to locate accurately, the manufactured sand core is easy to deform and break, and it is difficult to ensure the dimensional accuracy of the flow channel. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a 78A0406M valve body and its processing technology. The assembly and positioning of the sand core is accurate, the sand core is stable, and the size of the flow channel is accurate. [0004] Technical scheme of the present invention: [0005] A 78A0406M valve body, characterized in that: it includes a valve body; the valve body is designed in a block shape, five flow channel ports are designed in front of the...
