Abstract

The invention discloses a method for manufacturing a shell of an electronic controller for a vehicle. The method comprises a step of manufacturing a mould, a step of die-casting, a step of removing material handles and sludge ladle from a blank, a step of removing burrs, a step of vibration grinding, a step of testing air-tightness, a step of checking flatness and position of a mounting hole, a step of washing and drying and a step of warehousing finished products. The method adopt high-tech means to ensure design of the mould and high manufacture precision, and selects proper die-casting equipment to ensure small deformation of a formed product. Through the step of vibration grinding, proper vibration grinding equipment, a grinding material, washing agent and proper process parameters are selected, after the surface of the formed product is washed, the product has high cleanliness (surface tension reaches 56mN/m) and high dimension precision; actual operation process parameters are set for key steps, such as die-casting, grinding, washing and the like so that the method adapt to standard production and mass production of the products.

Description

technical field [0001] The invention relates to the technical field of precision die casting, in particular to a method for manufacturing a vehicle electronic controller housing. Background technique [0002] In the current technology, the housings involving the electronic controller of the automobile airbag and the main control device of the engine ignition are usually made of die-cast aluminum alloy. This type of housing has high precision in size and shape, high requirements on flatness and high cleanliness. , High requirements on appearance quality, thin wall of parts and poor structural rigidity, easy deformation during processing, light weight and so on. [0003] With the continuous development of our country's economy, the demand for automobiles has increased significantly, so the variety and demand for such products have increased significantly. However, because the current domestic conventional processing technology cannot meet product requirements at all, this type...
