Abstract

The invention discloses a processing technique for removing burrs of a die casting, comprising the following steps of: cleaning the die casting by an ultrasonic wave cleaning machine; sequentially cleaning the die casting in three water channels; soaking the die casting in a blended solution used for removing burrs; sequentially cleaning the die casting in the three water channels; cleaning the die casting by utilizing the ultrasonic wave cleaning machine; cleaning the die casting in each water channel for 15-30 seconds; and finally taking out the die casting, and drying by a blower gun. By adopting the processing technique disclosed by the invention, burrs or flashing on various die castings and casting hardware can be effectively removed, and the processing technique is especially applicable to smaller hardware and has wide market value.

Description

technical field [0001] The invention relates to the technical field of die casting processing, in particular to a processing technology for removing burrs from die castings. Background technique [0002] During the die-casting production process, due to cracks on the surface of the mold cavity, thorns or flashes are formed around the processed parts of the die-casting surface. Although these burrs are not large, they directly affect the quality of the product. [0003] Existing commonly used deburring methods include manual deburring, chemical deburring and electrolytic deburring, etc. There are various problems and deficiencies in the above-mentioned methods. Therefore, the prior art needs to be improved and perfected. . Contents of the invention [0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to adopt a new processing technology, which can not only remove the surface burrs or flashes of die-casting parts and ensure product q...
