Mould paint spraying device

Abstract

The invention relates to a mould paint spraying device, which comprises a spray pond, a holding barrel, a receiving barrel, a spraying rod, a slurry pump, a first conveying pipe, a second conveying pipe, a third conveying pipe, a fourth conveying pipe and a flexible pipe; the receiving barrel is fixed at a high position; a central hole is formed at the central part of the spray pond; the top of the holding barrel is open and is positioned below the central hole of the spray pond; the spraying rod comprises a rod body, a valve and a spray head; one port of the first conveying pipe extends into the bottom of the holding barrel, while the other port of the first conveying pipe is communicated with the liquid inlet of the slurry pump; the liquid outlet of the slurry pump is communicated with the lower port of the second conveying pipe, and the upper port of the second conveying pipe is communicated with one side of the top of the receiving barrel; the upper port of the third conveying pipe is communicated with the other side of the top of the receiving barrel, while the lower port of the third conveying pipe extends into the holding barrel; the upper port of the fourth conveying pipe is fixed on the receiving barrel; and one end of the flexile pipe is communicated with the lower port of the fourth conveying pipe, and the other end of the flexible pipe is communicated with the valve of the spraying rod.

Description

technical field [0001] The invention relates to a device for coating molds. Background technique [0002] When the foundry uses the resin sand process to produce the mold, the surface of the prepared mold needs to be coated with paint. When casting small castings, due to the small volume of the mold, the coating can be applied by dip coating. When casting large-scale castings, especially large-scale wind turbine castings, a single casting can weigh up to 20 tons, and the volume of the mold is very large. If the coating is applied by manual brushing, multiple operators are required to coat the mold. Brushing two to three times is labor-intensive and extremely low-efficiency, which will affect the production progress of the entire production workshop. Moreover, the coating tends to be uneven during manual brushing, and the thickness of the coating is difficult to control, which will affect the dimensional accuracy of the casting and reduce the quality of the casting.
