Description
technical field
The utility model relates to casting and molding technical field, is specifically related to a kind of casting alcohol-base paint spray equipment.
background technology
Sand casting is a kind of using sand as main Modeling Material, makes the conventional casting techniques of casting mold.Sand mold generally adopts gravitational casting, has during particular/special requirement and also can adopt the technique such as low pressure casting, centrifugal casting.The adaptability of sand casting is very wide, smallclothes, large part, simple part, Complex Parts, single-piece, all can adopt in enormous quantities.
In casting and molding process, sand mold inner chamber and core outer surface need brushing fireproof coating, and adopt and manually brush, one is waste time and energy, inefficiency, and two is that brushing is uneven, affects casting quality.But there is the defects such as pressure is high, impracticable in existing flush coater.
summary of the invention
The technical problems to be solved in the utility model is to provide a kind of casting alcohol-base paint spray equipment, to solve artificial brushing inefficiency, to waste large, ropy problem.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
Alcohol-base paint spray equipment use in a kind of casting, comprise contain appearance alcohol-base paint container tank, coating is carried out the spray gun that is atomized and threeway under compressed-air actuated effect; Coating efferent duct one end is stretched in container tank, the first interface of another termination threeway; Coating efferent duct is arranged painting material conveying pump; Second interface of coating input pipe one termination threeway, the other end connects spray gun; Coating input pipe arranges control valve; 3rd interface of paint return pipe one termination threeway, the other end stretches into container tank bottom space; Compressed air input pipe connects spray gun, and compressed air input pipe arranges control valve; The cross-sectional flow area of coating efferent duct is greater than the cross-sectional flow area of paint return pipe.
Above-mentioned casting alcohol-base paint spray equipment, coating efferent duct adopts the flexible pipe of DN13.
Above-mentioned casting alcohol-base paint spray equipment, paint return pipe adopts the flexible pipe of DN10.
Before alcohol-base paint spraying, coating is injected container tank, stir, now on coating input pipe, control valve is in closed condition, on compressed air input pipe, control valve is in closed condition, open and be coated with material conveying pump, container tank, coating efferent duct, threeway and paint return pipe form paint circulation system, whether normally observe backflow, the whether convection current of coating case inside courtyard, after the normal bubble-free that refluxes, pistol, shower nozzle distance workpiece about 30 centimetres, control valve on slow unlatching compressed air input pipe, open control valve on coating input pipe again, regulate suitably, start spraying operation.When stopping operation, first close control valve on coating input pipe, then control valve on closes compression air inlet duct, close and be coated with material conveying pump.The utility model improves brushing operating efficiency, has saved coating consumption, and coating quality is good.In addition, part coatings is back to container tank bottom space by paint return pipe, stirs container tank inside courtyard, prevents coating from precipitating, and improves the uniformity that coating exports, and plays the effect of the effect of anti-clogging spray gun and raising coating quality.Because coating input pipe inside courtyard itself has certain pressure, so compressed air gas consumption is less, by the aperture of control valve on control valve on adjusting coating input pipe and compressed air input pipe, obtain satisfied spraying effect.
accompanying drawing explanation
Below in conjunction with accompanying drawing to the further detailed description of the utility model:
Fig. 1 is schematic diagram of the present utility model.
In figure: 1 container tank, 2 are coated with material conveying pump, 3 coating efferent ducts, 4 control valves, 5 spray guns, 6 paint return pipes, 7 control valves, 8 compressed air input pipes, 9 coating input pipes.
Detailed description of the invention
As shown in Figure 1, alcohol-base paint spray equipment use in a kind of casting, comprise contain appearance alcohol-base paint container tank 1, coating is carried out the spray gun 5 that is atomized and threeway under compressed-air actuated effect.Coating efferent duct 3 one end is stretched in container tank, the first interface of another termination threeway.Coating efferent duct is arranged and is coated with material conveying pump 2, be coated with material conveying pump suction coating.Second interface of coating input pipe 9 one termination threeway, the other end connects spray gun.Coating input pipe is arranged control valve 4, to control fluid flow size in coating input pipe.3rd interface of paint return pipe 6 one termination threeway, the other end stretches into container tank bottom space, and alcohol-base paint in container tank is stirred in the backflow of coating, plays the effect of hydraulic agitation.Compressed air input pipe 8 connects spray gun, compressed air input pipe is arranged control valve 7.The cross-sectional flow area of coating efferent duct is greater than the cross-sectional flow area of paint return pipe, and the internal diameter of coating efferent duct is greater than the internal diameter of paint return pipe in other words.
Particularly, coating efferent duct adopts the flexible pipe of DN13.Paint return pipe adopts the flexible pipe of DN10.
The utility model achieves the stirring of alcohol-base paint in container tank by the reflux type of coating, makes the coating good evenness exported, avoids the blocking of spray gun, improve spray uniformity.
