Automatic sand blowing device

Abstract

The invention provides an automatic sand blowing device, and belongs to the technical field of mechanical equipment. The automatic sand blowing device comprises a fixing frame, a moving part, a driving device, a telescopic rod and an air knife, wherein the driving device is detachably installed on the moving part, and the driving device drives the moving part to reciprocate on the fixing frame. The telescopic rod comprises a fixed rod and a movable rod, the fixed rod and the movable rod can move relatively, the fixed rod is vertically installed on the movable piece, and the movable rod is fixedly connected with the air knife. The air knife can be provided with a plurality of tuyeres and horizontally reciprocate, the height of the air knife is adjustable, and the air volume of the tuyeres is controllable. In this way, floating sand on the surface of a sand mold or in a mold cavity can be effectively cleaned.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, in particular to an automatic sand blowing device. Background technique [0002] In the process of the foundry industry, after the sand core is formed, it is necessary to manually clean the floating sand on the surface and inner cavity of the sand core before dipping or flow coating, especially in the most advanced 3D printing sand core technology at present, the sand core surface and interior The sand blowing workload is particularly large, but the existing sand blowing process is still manual sand blowing. The advantage of manual sand blowing is that it can thoroughly clean up the sand and floating sand in the inner cavity of complex sand cores, which is of great help to the quality of dip coating and flow coating of sand cores. Low, and the dust content in the air of the sand blowing room is high, which is harmful to human health, which greatly affects the development of the 3D printing ca...
