[0002] The blades of automobile axial flow fans are often made of plastic structure formed by injection molding process; the surface of the blade and the outer edge of the reinforcement ring of the injection molded parts have many tiny burrs, which makes the surface not smooth, and the finish is not high and the burrs are not beautiful. , it seems that there is no grade, and it may cause additional noise and other hazards. In order to improve the grade of the workpiece, it is necessary to perform sandblasting and polishing on the outer surface of the injection molded blank; due to the complex structure of the fan blade, the surface blasting process is complicated; resulting in existing Many injection molding fans in China have given up the sandblasting process

The invention discloses a surface treatment system for automobile plastic parts, which comprises the automobile plastic parts to be sandblasted. It includes a central hub, and several blade units distributed in a circular array along the axis of the central hub, the root of each blade unit is integrally connected to the side wall of the central hub, and a The reinforcing ring, the blade end of each blade unit is integrally connected to the annular inner edge of the reinforcing ring; the structure of the present invention is simple, and each blade unit can be sand blasted one by one, the process consistency is good, and the whole process only It is necessary to control the spraying intensity to achieve a complete sandblasting process. In all processes, there is no need to manually adjust the attitude of the sprayed workpiece, adjust the spraying angle, etc., and improve the automation of the sandblasting process.
Description
technical field [0001] The invention belongs to the field of surface treatment of automobile plastic parts. Background technique [0002] Automobile axial fan blades often adopt a plastic structure formed by injection molding process; there are many tiny burrs on the blade surface and the outer edge of the reinforcement ring of the injection molded parts, which makes the surface not smooth, and the finish is not high and multiple burrs are unsightly. , it seems that there is no grade, and it may cause additional noise and other hazards. In order to improve the grade of the workpiece, it is necessary to perform sandblasting and polishing on the outer surface of the injection molded blank; due to the complex structure of the fan blade, the surface blasting process is complicated; resulting in existing Many injection molding fans in China have given up the sandblasting process. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies...
