A self-priming pump pump body sand casting demoulding device

Abstract

The invention relates to the technical field of sand casting equipment, in particular to a self-priming pump pump body sand casting demoulding device, which includes a shakeout tank, an upper sand box and a lower sand box; the lower sand box is filled with sand material, filled completely and spread evenly , then take out the lower bottom plate, fix the lower bottom plate on the lower sand box, at this time, drive the rotating shaft to rotate through the rotating motor, so as to turn the lower sand box over so that the lower bottom plate is located under the lower sand box, and is driven down by the lifting motor The sand box and the lower bottom plate move down until the fixed seat is aligned with the fixed plate; drive the upper sand box to align with the lower sand box, fill the sand box with sand material, and then take out the mold frame; after taking it out, drive the upper top plate and the upper The sand box is moved down, the casting cavity is formed to carry out filling casting, after the casting is formed, the casting is taken out; the lower sand box is reset, the lower bottom plate is removed, and the sand material is pounded out from the upper sand box and the lower sand box by a ramming rod , falls on the filter screen, and the sand is filtered and then falls into the sand tank for recovery.

Description

technical field [0001] The invention relates to the technical field of sand casting equipment, in particular to a sand casting demoulding device for a pump body of a self-priming pump. Background technique [0002] The self-priming pump is a self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. There is no need to install a bottom valve in the pipeline, and it is only necessary to ensure that there is a quantitative suction liquid stored in the pump body before work. Sand casting is a casting method for producing castings. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Because the molding materials used in sand casting are cheap and easy to obtain, and the casting mold is easy to manufacture, it can be adapted to the single-piece production, batch production and mass production of self-priming pump b...

Problems solved by technology

[0003] The existing sand casting demoulding process is usually done manually, the operation is complicated, and the accuracy cannot be guaranteed, and the existing sandbox casting is often performed manually after sand casting, because the molding sand needs to be removed before pouring. Compaction, which in turn increases the difficulty of cleaning up the staff and increases the workload
