Problems solved by technology

[0002] In the past, in the casting production process, the mold and core coatings were mostly painted manually, and the thickness of the coating was often uneven, which was difficult to control, and some places could not be brushed at all, so the dimensional accuracy of the casting could not be guaranteed, and only the processing cost would be increased. Moreover, the labor intensity of workers is high, and it is easy to pollute the environment.
There are also those who use the pressure spraying machine to spray, directly add the air pressure to the liquid surface, but its safety hazard is great, often causing accidents, and it is impossible to quantitatively control the spray volume, and the spray quality cannot be guaranteed.

Embodiment Construction

[0018] see Figure 1 ~ Figure 3 , its working process is: connect the cylinder body 2 with the air pressure (or hydraulic pressure) and the control system, the pressure fluid inlet and outlet 25 intake air, the power piston 1 moves upward, the suction and injection piston 13 moves upward, and the one-way valve 15 opens , the suction pipe 17 sucks the paint into the suction and spray cylinder 12, and the air outlet 24 exhausts the air. When the power piston 1 travels to the top dead center, the liquid suction action is completed; the inlet and outlet 3 of the pressure fluid are sucked into the air, and the power piston 1 moves toward The downward movement, the suction and spray piston 13 moves downward, and the nozzle 7 is placed in the proper position of the mold. The suction and spray piston 13 presses the paint into the nozzle 8 and the nozzle 7, and the paint is evenly sprayed in a 180° plane shape. When the 1 line reaches the bottom dead center, the spraying action is comp...

Abstract

The invention relates to a casting dope ejector. Wherein, it comprises cylinder 2, cylinder cover 9, and power piston 1 with piston rod 11; the cylinder 2 or the cylinder cover 9 at two sides of power piston 1 has the inlet and outlet 3, 25 of pressure liquid; the lower end of piston rod 11 has adsorption piston 13 and adsorption cylinder 12; the upper side of cylinder 12 has gas outlet 24 while its bottom has adsorption tube and ejector. The invention has uniform coat, improved accuracy and quality of casting element and reduced cost.

Description

technical field [0001] The invention relates to the technical field of mold and core processing in casting production, in particular to a casting paint spraying machine. Background technique [0002] In the past, in the casting production process, the mold and core coatings were mostly painted manually, and the thickness of the coating was often uneven, which was difficult to control, and some places could not be brushed at all, so the dimensional accuracy of the casting could not be guaranteed, and only the processing cost was increased. Moreover, the labor intensity of the workers is high and it is easy to pollute the environment. There are also those who use pressure spraying machine for pressure spraying, which directly adds air pressure to the liquid surface, but its safety hazard is large, often causing accidents, and it is impossible to quantitatively control the spray volume, and the spraying quality cannot be guaranteed. Contents of the invention [0003] The obj...
