Molding sand production system for sand mold precision casting

Abstract

The invention relates to a molding sand manufacturing system for precision casting of a sand mold. The molding sand manufacturing system comprises a bottom plate, two loosening devices, four shaping devices, a flattening device and two blocking plates, wherein the blocking plates are symmetrically arranged at the upper end surface of the bottom plate in a front and back way; the two loosening devices are symmetrically arranged at the upper end surface of the bottom plate in a left and right way, and are positioned at the left end and right end of the corresponding blocking plate; the four shaping devices are symmetrically arranged at the upper end surface of the bottom plate in a front and back way, and are positioned at the outer side of the corresponding blocking plate; the flattening device is arranged at the upper end surface of the middle part of the bottom plate, and is positioned in the middle part of the corresponding blocking plate. The molding sand manufacturing system can solve the problems that the sand and soil in the artificially manufactured molding sand cannot be uniformly stirred, the degree of loosening of the sand mold cannot be well controlled, the flatness of the artificially flattened upper sand and soil is poor, the sealing property of the container is poor in the manufacturing process of the sand mold, and the like. The molding sand manufacturing systemcan realize the integrated molding sand manufacturing function.

Description

technical field [0001] The invention relates to the technical field of sand mold casting, in particular to a molding sand production system for sand mold precision casting. Background technique [0002] Sand mold precision casting is a casting method that produces castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. 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. [0003] In the process of sand casting, the molding sand must be made first, and then the molten metal is poured into the sand mold. The quality of the sand mold production determines the quality of the casting. In the existing molding sand production process, artificial sand The internal sand is not stirred evenly, and ther...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a molding sand production system for sand mold precision casting, which can solve the problem that the sand inside the existing artificial sand cannot be stirred evenly, the artificially leveled upper layer of sand has poor flatness, and the porosity of the sand mold is not very good. control, poor sealing of the container when making sand molds, etc.; it can realize the function of integrated molding sand production, which can stir the inner sand of the molded sand evenly, and the mechanically leveled upper layer of sand has high flatness, and can control the porosity of the sand mold very well. , The advantages of strong airtightness of the container for making sand molds
