The method of lost foam casting anode steel claw and the white mold of anode steel claw formed

Abstract

The invention provides a lost foam casting method of an anode steel claw and an anode steel claw white die formed by the lost foam casting method. According to the technical scheme, the lost foam casting method of the anode steel claw comprises the following steps: (1) assembling a white die, namely, downwards placing a claw leg part white die of the anode steel claw, mounting a connection arm white die on the claw leg part white die, mounting a square table white die on the connection arm white die, and finally placing a feed head on the square table white die; (2) brushing lost foam casting coating on the external surface of the assembled white die in the step (1); (3) drying the white die in the step (2) in a drying room; (4) placing the white die in the step (3) in a sand box and performing sand filling operation; (5) performing vacuumizing operation; (6) pouring molten steel; and (7) cooling and forming, namely, standing after pouring the molten steel and waiting for cooling and forming. Through the method, the number of the feed heads is reduced; the molten steel is saved; meanwhile, in a subsequent feed head removal process, the machining area is also reduced, and thus the machining difficulty is reduced.

Description

technical field [0001] The invention relates to a casting method of an anode steel claw in the field of casting technology and an anode steel claw cast by the method, in particular to a method for lost foam casting of an anode steel claw and the formed white mold of the anode steel claw. Background technique [0002] Lost foam casting, also known as solid casting, is to bond and combine paraffin or foam models similar in size and shape to castings to form a model, brush and apply refractory materials and dry them, bury them in sand for vibration molding, and pour them under negative pressure conditions , so that the model is vaporized, the metal liquid occupies the position of the model, and the casting method is formed after solidification and cooling. Since the lost foam is a new technology with nearly no margin and precise molding, this process does not require mold taking, no parting surface, and no sand core, so the casting has no burrs and reduces the dimensional error...

AI Technical Summary

Problems solved by technology

The defects of the prior art are as follows: 1. Because of this modeling and casting method, risers must be placed on the white molds of the eight claw legs. After cooling and setting, the risers must be removed, so pouring wastes molten steel; 2. Since the risers are set on the claw legs, after cooling and forming, the risers of the eight claw legs need to be removed, and the processing area is large; 3. Because the eight claw legs are not on the same straight line, it is necessary to use multiple milling heads The machine tool is operated to remove the riser, which is difficult to process; 4. The price of the multi-milling head machine tool is very high, which also increases the manufacturing cost of the anode steel claw virtually; 5. The models formed in the prior art are all solid, which wastes white molds. Prolong the gasification time of the white mold, and the surface finish of the cast steel claw is low
