Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing:

[0032] In the picture:

[0033] as attached figure 1 shown

[0034] A kind of rapid sand mold preparation method specifically comprises the following steps:

[0035] S101: Sand mold preparation work, clean the raw sand, remove impurities and dust, filter the raw sand through a stainless steel mesh screen, and then rinse it. After washing, it is dried, and the dried raw sand is placed in the In the sand box, leave a mold cavity in the sand box, and then bond the original sand with an adhesive to form a sand mold;

[0036] S102: Anti-flow treatment process after the sand mold is formed, combined with the attached figure 2 As shown, it specifically includes the following steps:

[0037] S201: Internal treatment of the cavity of the sand mold. The inner wall of the formed cavity is smeared with smooth auxiliary materials. After the smearing, the inner wall of the cavity i...

Abstract

The invention provides a rapid sand mold preparation method, and belongs to the field of sand mold casting, and the rapid sand mold preparation method specifically comprises the following steps: sand mold preparation work, anti-flowing treatment procedure after sand mold formation, sand mold casting preparation operation, casting dustproof protection of a casting, sand mold manufacturing special conditions and sand mold modeling matters needing attention. The method is simple to operate and easy to master, the casting effect of a sand casting can be guaranteed, crude sand can be prevented from flowing, the stability of a cavity is guaranteed, and the problems that according to an existing sand mold preparation method, a crude sand mold is prone to flowing after being formed, the casting effect is affected, the preparation effect is poor, and the sand mold is prone to being affected by dust are fully solved; the dustproof protection effect can be achieved, the dust influence is avoided, then the casting forming effect is guaranteed, the sand hole or crack condition is avoided, and the casting smoothness is improved.

Description

technical field [0001] The invention belongs to the technical field of sand mold casting, and in particular relates to a rapid sand mold preparation method. Background technique [0002] The sand mold is the casting cavity in the casting production process. [0003] PRIOR ART Sand casting refers to a casting method in which castings are produced in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. [0004] Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings. It has been the basic process in casting production for a long time. [0005] However, the existing sand mold preparation method has the problems that the original sand mold is easy to flow after molding and affects the casting effect, the preparation effect is poor and the problem is easily affected by dust. ...
