Technical Field

[0001] The utility model belongs to the technical field of infrared welding of instrument panels, in particular to a welding device with a special draft angle for welding ribs in an airbag area of ​​an instrument panel. Background Art

[0002] In the traditional infrared welding process of instrument panels, the welding methods for airbag boxes and air ducts are all in the form of one-piece welding, where the upper tire mold drives the parts to be pressed down as a whole. This welding method is only applicable when the draft angle of the ribs in the airbag area and the ribs in the air duct area of ​​the instrument panel body is consistent. However, due to the continuous innovation and improvement of product shape by customers, there are more and more differences in the welding rib angles between the airbag area and the air duct area of ​​the instrument panel, which makes it impossible to complete the welding work with the traditional welding method.

[0007] Furthermore, it also includes a plurality of weight-reducing holes arranged on the supporting back plate.

[0008] The beneficial effects of the utility model are:

[0009] At present, in order to meet the overall requirements of customers for product shape, this patent, based on the original welding form, separates the airbag box area through the upper mold and adds a separate servo motor to drive the airbag box to complete the separate control and welding of the air duct airbag box. The utility model is more flexible in adjusting the welding parameters and ensures the overall welding work of the parts. BRIEF DESCRIPTION OF THE DRAWINGS
