The pattern-less sand mold was used as the research object, surface quality of sand mold was carried out by using surface abrasion tester. In this paper, the influence of sand material such as the types of sand, resin contents and extrusion pressure on the surface quality was studied through the single-factor test. The results showed that: different sand mold had different surface abrasive resistance. The angle coefficient of sand has a great influence on the surface abrasive resistance of the sand mold. With the increase of extrusion force, the surface abrasive resistance of sand mold increased. And as the resin content increased, the surface abrasive resistance of sand mold continued to increase. |
