Grinding working table for casting molds

Abstract

The invention discloses a grinding working table for casting molds. The grinding working table comprises a bracket; the front side of the upper end of the bracket is hinged to one end of the grindingtable through a hinge, the right side wall of the other end of the grinding table is fixedly connected with a limiting column in an inserted mode, a support plate is formed on the bracket, and an arc-shaped limiting groove is formed on the side wall of the support plate; the limiting column is connected with the limiting groove in an inserted mode, a pair of limiting holes is formed in the limiting column, an upper installation groove and a lower installation groove are formed on the side wall of the support plate of the upper and lower sides of the limiting groove, and the upper installationgroove and the lower installation groove are connected with upper ball plungers and lower ball plungers in a threaded mode; and moving grooves are formed in the upper and lower sides of the upper endsurface of the grinding table, L-shaped clamping plates are connected with the interiors of the moving grooves in an inserted mode, second bolts are connected to the upper ends of the clamping platesin a threaded mode, pressing plates are fixedly connected to the lower ends of the second bolts, multiple pairs of shrinkage pools are formed on the opposite inner walls of the moving grooves, and thelower ends of the clamping plates are connected to a pair of positioning ball plungers in a threaded mode. The height of the grinding table can be adjusted, the grinding time is saved, and the grinding working table is suitable for grinding molds with different types.

Description

Technical field: [0001] The invention relates to the technical field of moulds, in particular to a grinding workbench for casting moulds. Background technique: [0002] After the casting mold is produced, the surface is prone to roughness, strain, corrosion, pitting and other adverse conditions, requiring workers to polish and repair the mold. Due to the influence of mold structure, style, model and other factors, the mold fixed on the grinding table sometimes requires the grinder to bend over to work, which will easily cause lumbar muscle pain or even inability to stand upright for a long time, and the mold itself is heavy. , When changing the grinding position, the operator needs to move constantly, which is time-consuming and laborious. It takes up to 7 to 8 hours to polish a pair of molds in the prior art. [0003] In view of the above-mentioned defects, the designer actively researches and innovates in order to create a new type of structure for the grinding workbench ...
