Automatic sand mold casting device

Abstract

The invention discloses an automatic sand mold casting device, and belongs to the technical field of sand mold casting. The automatic sand mold casting device comprises a fixed box body, a balance placement assembly, a tamping assembly and a cleaning assembly, an extension edge is fixed at the upper end of the fixed box body, the cleaning assembly is fixed at the upper end of the extension edge, vertical plates are fixed on the inner sides of two ends of the extension edge, a transverse rod is fixed to the upper ends of the two vertical plates, the tamping assembly is fixed to the transverse rod, the balance placement assembly is arranged below the tamping assembly, and a workbench is fixed to the bottom of the balance placement assembly and fixed to the upper end of the fixed box body. According to the casting device, the heights of the two ends of an adjusting block can be adjusted through screwing-in of tensioning screws, then the placing levelness of the whole sand mold can be adjusted, the distribution uniformity of sand is improved, and the mold manufacturing quality is improved.

Description

technical field [0001] The invention belongs to the technical field of sand casting, in particular to an automatic sand casting device. Background technique [0002] The automatic molding machine is a casting equipment used to make sand molds. Its main functions are: filling sand, filling loose molding sand into the sand box; compacting sand, compacting the loose molding sand in the sand box through different methods such as vibration compaction, compaction, shock pressure, and injection pressure, so as to make the sand mold It has the necessary strength in the process of handling and pouring; the mold is lifted, and the mold is taken out of the compacted sand mold by using different mechanisms. The most common mold is made of molding sand, which has good fluidity, easy molding, and low price. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting, so it is widely used in casting applications. [0003] However, the existing sand casting device do...

Problems solved by technology

[0003] However, the existing sand casting device does not have a level detection device, and it is easy to place the device skewed during use, which will cause uneven distribution of sand during the sand shaking process. In addition, the existing sand casting device cannot judge The compression ratio of the original sand makes the sand mold not strong enough or too strong, which is not good for casting
