Description

Technical Field

[0001] The utility model relates to the technical field of casting processing, in particular to a dust removal device for a casting mould. Background Art

[0002] Casting is a method of pouring liquid metal into a casting cavity that is adapted to the shape of the part, and then cooling and solidifying it to obtain a part or blank. The material to be cast is mostly a metal that was originally solid but heated to a liquid state (e.g., copper, iron, aluminum, tin, lead, etc.), and the material of the mold can be sand, metal or even ceramic. Depending on the requirements, the methods used will also be different.

[0003] At present, in the process of mold casting, the mold needs to be disassembled when demolding, and the mold needs to be assembled together when casting again. The mold needs to be cleaned before casting to clean the residues remaining inside the mold. Therefore, a casting dust removal device produced by mold casting is needed. Many of the commonly used casting dust removal devices for mold casting production are manually cleaned and dusted with a handheld brush. Not only is the dust removal efficiency low, but a large amount of dust is generated during the dust removal process, which reduces the air quality of the working environment. Utility Model Content

[0005] A dust removal device for a casting mold comprises a cleaning roller, the top of the cleaning roller is rotatably connected to one end of a suction pipe, the other end of the suction pipe is connected to a casing, an impeller is installed in the casing, the rotating shaft of the impeller passes through the casing and is connected to the output end of a motor, and the cleaning roller is transmission-connected to the motor through a transmission assembly.

[0006] Furthermore, the transmission assembly includes a first bevel gear connected to the output end of the motor, the first bevel gear is transmission-connected to the second bevel gear, the second bevel gear is transmission-connected to the driving gear through a transmission shaft, the driving gear is meshed with the transmission gear, and the transmission gear is sleeved on the top of the cleaning roller.

[0007] Furthermore, the motor is mounted on a fixed disc, and the fixed disc is mounted on the outer wall of the housing through a supporting column.

[0008] Furthermore, a shielding plate is provided below the transmission gear, and the shielding plate is installed on the outer wall of the shell through a bracket.

[0009] Furthermore, the shell is provided with a handle, and the handle is provided with a start switch.

[0010] Furthermore, an air outlet pipe is provided on a side of the housing away from the motor, and the air outlet pipe is connected to the air suction device through a pipeline.

[0011] Furthermore, brushes are evenly distributed on the cleaning roller.

[0012] Furthermore, the shell, handle and air suction pipe are divided into left and right parts.

[0013] Furthermore, the cleaning roller is provided with a through hole extending along its axial direction, and the through hole is connected to the inside of the shell through an air suction pipe.

[0014] Due to the adoption of the above technical scheme, the beneficial technical effect of the utility model is: the utility model starts the motor, drives the cleaning roller to rotate through the transmission component, so as to clean the dust on the mold. The motor can drive the impeller to rotate. Through the rotation of the impeller, negative pressure is formed in the outer casing, and the cleaned dust is sucked into the outer casing, thereby preventing the staff from inhaling a large amount of dust when cleaning the mold, thereby ensuring the quality of the working environment of the staff.
