Embodiment Construction

[0025] The following structural drawings describe the invention in further detail.

[0026] A method for producing an aluminum alloy airbag support arm with a horizontal squeeze casting machine, wherein the specific application is as follows:

[0027] (1) Mold pouring and overflow design

[0028] The flow state and pressure distribution of the liquid flow are used to realize the smooth filling and sequential solidification of the parts under pressure; the design of the ingate includes the position, shape and size of the ingate. The opening of the ingate should ensure that there are few or no pores and shrinkage defects inside the part; the appearance of the part should be free from cold insulation and the surface should be smooth and complete; the selection of the position of the ingate is the first issue to be considered in the design of the gating system; When designing the position of the inner gate, the structural shape, wall thickness, shrinkage deformation, alloy type, ...

Description

technical field [0001] The invention belongs to the technical field of material forming of an aluminum alloy airbag support arm of an automobile, and in particular relates to a method for producing an aluminum alloy airbag support arm with a horizontal extrusion casting machine. Background technique [0002] The airbag support arm is the core part of the wheel drive axle of the car. It is connected with the car box, the shock absorber airbag module and the drive system. It can bear the rear load of the car, support the drive axle and play a buffer role for the shock absorber airbag. In the driving state of the car, it is subjected to variable shock and damping loads. The safety and reliability of the airbag support arm directly affects the driving reliability of the vehicle and the life safety of the vehicle occupants, and it plays a very important role in the auto parts production industry. The airbag support arm will be affected by various random loads during the driving ...
