Problems solved by technology

[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

Abstract

The invention discloses a surface treatment process system for automobile plastic parts, comprising a liquid sandblasting and grinding box, wherein an inclined guide plate is arranged in the liquid sandblasting and grinding box, and the upper side of the guide plate is a jet grinding cavity , the lower side of the baffle is provided with a vertical baffle, the left side of the baffle is a waste liquid cavity, and the right side of the baffle is a lifting motor cavity; the short end of the baffle is provided with Leakage hole; this scheme does not need to manually adjust the attitude of the workpiece to be sprayed, adjust the spray angle and other interventions in all processes, and improve the automation of the sandblasting process.

Description

technical field [0001] The invention belongs to the field of auto parts processing. 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 in the prior art, the p...
