An assembled follow-up sand box and an assembling method for the follow-up sand box

Abstract

The present invention relates to an assembled mold-fitting sand box in the field of casting technology and a method for assembling the mold-fitting sand box, wherein the assembled mold-fitting sand box includes several general-purpose sand boxes stacked in layers, and several sand-blocking plates are assembled in the general-purpose sand box And several support plates for supporting the sand barrier and the universal sand box, the sand barriers are assembled and superimposed in the universal sand box to form the continuous inner wall of the molding sand box. In the case of using a general-purpose sandbox for the molding sandbox of the present invention, appropriate barrier areas can be set in the general-purpose sandbox according to the shape and size of the casting by using a sand-blocking plate and a bottom-layer sand-blocking plate to reduce the amount of sand used in the quicksand molding process. quantity, reduce the sand-iron ratio in casting, save production cost, and shorten the cooling time of the casting pressure box and shorten the production cycle; and the molded sand box of the same casting product can be reused after one assembly, which improves the mass production efficiency. For large-scale It is of great significance to reduce casting cost and increase production capacity in casting production.

Description

technical field [0001] The invention relates to the field of casting technology, in particular to an assembled molding-type flask used for reducing the amount of sand used in castings in the molding or core-making process and a method for assembling the molding-type flask. Background technique [0002] Large-scale rotary and large-scale castings have various shapes, but for a long time, due to the restriction of the production quantity and the production cost of special flasks, the casting production process of such castings has widely used several layers of stacked general-purpose flasks. When using a general-purpose sandbox, since the shape and size of each part of the casting are different from the size of the general-purpose sandbox, when the casting is placed in the sandbox and filled with sand, the small-sized parts correspond to a larger amount of sand in the general-purpose sandbox, and the local sandfill The amount of sand is larger, and the waste of sand around and...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the problems of large sand-iron ratio, high production cost, long quicksand molding time and slow cooling speed when using a general-purpose sand box for casting large-scale castings in the prior art, and provides an assembled sand box to reduce the casting process. Medium sand-iron ratio, reducing sand shakeout workload and improving cooling efficiency
