Problems solved by technology

However, the casting number produced by this process has the disadvantages of long hardening time, low work efficiency, insufficient surface finish, difficult control of hardening time, and high production cost.
In particular, sand cores made of ester-hardened sodium silicate no-bake sand are poorly formed, and often have defects such as collapse, cast nodules, pits, and missing defects, which brings great difficulties to subsequent cleaning work, resulting in font size accuracy that cannot meet the drawings design requirements, reduce the aesthetics of the font size, and affect the quality of product acceptance

Abstract

The invention discloses a precoated sand typecasting sand core manufacturing device. The precoated sand typecasting sand core manufacturing device consists of a hot core box 1, a supporting frame 2 and a typecasting mold 3, wherein the hot core box is in a box body structure of which the bottom surface 4 is a plane; a typecasting mold inlaying groove 5 is formed in the bottom surface 4; the supporting frame 2 consists of a hot core box support 6 and a heating mechanism 7; the typecasting mold 3 comprises a typecasting base block 8 and a typecasting body 9; and the thickness of the typecasting base block 8 is the same as the depth of the typecasting mold inlaying groove 5. The invention further discloses a method for manufacturing a typecasting sand core by the precoated sand typecasting sand core manufacturing device. In the method, precoated sand consisting of silica sand, phenolic resin, urotropin and calcium stearate is adopted, and a self-hardening technology of ester hardening water glass sand is replaced with the hot hardening technology of the precoated sand; and in the manufacturing and production of the typecasting sand core, manufacturing labor hours can be reduced, production efficiency is improved, the molding rate of the typecasting sand core is increased, the molding quality of the sand core and the molding quality of workpiece typecasting are improved, production consumption is reduced, and manufacturing cost is reduced.

Description

technical field [0001] The invention relates to a casting sand core production device and its application, in particular to a production device for a coated sand casting core and a method for making a coated sand casting core using the same. Background technique [0002] With the rapid development of the rail transit industry, the quality management requirements for important parts of trains, such as bolsters and side frames, are also getting higher and higher. The casting sequence number, production date, manufacturer code, and country code on castings There are clear requirements for the clarity of cast characters, and it has been included in the product acceptance criteria. At present, the casting of bolsters and side frames in production mostly adopts the self-hardening process of ester-hardened water glass sand. , pounding, natural hardening in the air, mold removal and other processes to make sand cores of font size. However, the casting number produced by this proce...
