Automatic sand mold casting device

Abstract

The invention relates to the technical field of sand mold casting, in particular to an automatic sand mold casting device. The device is characterized in that four locking universal wheels which are symmetrically arranged are fixedly connected to the four corners of the bottom of a casting table correspondingly, a sand storage tank is located above the casting table, and the bottom of the sand storage tank communicates with an L-shaped material guide pipe; and a material conveying mechanism is arranged in the vertical end of the L-shaped material guide pipe, four supporting columns which are vertically and symmetrically arranged are fixedly connected to the upper side of the casting table, and the ends, away from the casting table, of the four supporting columns are fixedly connected with the bottom of a sand groove box. According to the device, a conveying mechanism is arranged to automatically convey sand, a reciprocating translation mechanism is arranged to drive a trowelling push plate to horizontally move, trowelling operation can be carried out, manpower is saved, trowelling quality is high, sand mold forming quality is improved, a tamping mechanism is arranged to tamp the sand, and an ejection mechanism is arranged to automatically eject out a sand mold in a sand groove box. Material taking is convenient, manpower is saved, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sand casting, in particular to an automatic sand casting device. Background technique [0002] Sand casting refers to the casting method of producing castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting methods. Because the molding materials used in sand casting are cheap and easy to obtain, the casting molds are easy to manufacture. It can be adapted to piece production, batch production and mass production. For a long time, it has been the basic process in casting production. The automatic molding machine is a casting equipment used to make sand molds. Its main functions are: filling sand, loosening The molding sand is filled into the sand box; the sand is compacted, and the loose sand in the sand box is compacted by different methods such as vibration, compaction, shock pressure, and injection pressure, so that the sand mold has the necessary strength ...

AI Technical Summary

Problems solved by technology

[0003] In the automatic sand casting technology, the molding sand raw materials need to be transferred between different equipment during the process from conveying to compacting and forming. The operation steps are cumbersome, which affects the processing efficiency, and the equipment is huge, takes up space, and maintenance is troublesome. Secondly, the molding sand is In the forming mold, it is necessary to manually smooth the upper layer, which is a waste of manpower, and the processing quality is low, and the waste of sand mold raw materials is serious
