Description

Technical Field

[0001] The utility model relates to the technical field of intake manifolds, in particular to an intake manifold quick-insert nozzle welding structure. Background Art

[0002] The intake manifold consists of two major components: the intake manifold body and the nozzle. The orientation of the nozzle is often related to the position of the counterpart and cannot be changed. In addition, to ensure sealing, there is a step on the nozzle, and the roughness of the step to the nozzle end surface must be very high. Due to these factors, the nozzle structure is difficult to demold. Therefore, the nozzle structure is often installed as a separate component in the intake manifold assembly. Existing nozzle structures are all assembled by vibration friction welding the pre-made plastic nozzle to the intake manifold assembly.

[0003] After the existing plastic nozzle welding structure is welded, gaps may exist in the welding area, which may easily cause air leakage. To address the above problem, the present application designs an intake manifold quick-insert nozzle welding structure. Utility Model Content
