Abstract

The invention relates to a casting process for batch production of column shoes and belongs to the field of casting. The casting process comprises the following steps: arranging a workpiece model and a runner model in demineralization and forming sand moulds by utilizing self-hardening sand; then taking out the workpiece model and the runner model, connecting the sand moulds together in series, forming a pouring cup hole in the middle, connecting to transverse runners, arranging a pouring cup on the hole, fixing the sand moulds connected in series on a support plate and performing workpiece pouring from the pouring cup. The casting process can realize batch production, lower the cost, reduce the labor intensity and meet the production needs.

Description

technical field [0001] The invention relates to a casting process for column shoes, in particular to a casting process for mass producing column shoes, which belongs to the field of casting. Background technique [0002] Column shoes are widely used as the bottom foundation of supporting columns in coal mines. Due to the large area of ​​the bottom, there are edges that limit the supporting columns. It is a component that improves the safety of the columns and increases the force-bearing area of ​​the columns. According to the existing production technology, if the column shoes are mass-produced, it is necessary to set multiple sand cores in multiple sand boxes to form sand molds, and then pour them into the sand molds. Using this method to cast products is very cumbersome, and A lot of molten iron will be wasted. This method of setting a single sand core in a single sand box is not conducive to using a larger ladle for pouring. Only the molten iron of a single column shoe ca...
