Casting molding method

Abstract

The invention relates to a casting molding method, and relates to the technical field of casting technology. The casting molding method comprises the processes of smelting, sand conditioning, core making, molding and clearing. The casting molding method specifically comprises the steps that firstly, molding sand obtained through sand conditioning is subjected to the core making process to obtain a sand core and a mold; secondly, molding is conducted with the utilization of molten iron obtained through melting and the sand core and the mold obtained through core making, and a cast product is obtained; and clearing is conducted finally. The casting molding method is characterized in that the molding sand adopted by the casting molding method is renewable sand, and after molding is conducted, the used sand is returned back to the sand conditioning process to be processed; waste iron materials and waste castings obtained through the clearing process are returned back to the smelting process for smelting and reused. According to the casting molding method, the molding sand can be reused, the production efficiency is high, cyclic utilization of the waste iron and the waste castings can be archived, casting materials are saved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a casting molding method. Background technique [0002] Casting technology is the technology and method of producing castings by applying casting related theory and systematic knowledge. Including molding material preparation, molding, core making, metal melting, pouring and solidification control, etc. Sand casting is a traditional casting process that uses sand as the main molding material to make molds. Sand casting has a wide range of adaptability, small pieces, large pieces, simple pieces, complex pieces, single pieces, and large batches can be used. In the prior art, sand casting also has some disadvantages: because each sandy mold can only be poured once, the mold is damaged after the casting is obtained and must be reshaped, so the production efficiency of sand casting is low. In addition, scrap iron and scrap castings will be produced during molding, which cannot be q...

AI Technical Summary

Problems solved by technology

In the prior art, sand casting also has some disadvantages: because each sand mold can only be poured once, the mold is damaged after the casting is obtained, and must be reshaped, so the production efficiency of sand casting is low

In addition, scrap iron and scrap castings will be produced during molding, which cannot be quickly and effectively collected and reused in the prior art, resulting in waste of materials and increased casting costs
