Description

Forming equipment for automatic layering and reciprocating bending of instrument board fabric hinge

Technical Field

The utility model belongs to the technical field of automobile interior trim inlay injection molding, and particularly relates to forming equipment for automatic layering and reciprocating bending of an instrument panel fabric hinge.

Background

At present, some vehicle type manufacturers mostly adopt high-strength and high-flexibility latticed fabrics to manufacture the air bag box hinge. In order to realize full-automatic inlay injection molding of the latticed air bag box fabric hinge, the primary task is to solve the problem of automatic layering of the fabric hinge. However, the mesh fabric hinge is of a multi-mesh structure, and the conventional sucking disc, the air needle and the non-contact sucking disc cannot meet the requirement of automatic layering.

With the improvement of the capacity of the copilot airbag, the fabric hinge with a knitting functional area or a double-layer sewing functional area is mostly adopted as an unfolding hinge for airbag blasting by the airbag of part of vehicle instrument board airbags. However, as the two fabric hinge forming processes are relatively complex, a part of projects gradually adopt new fabric hinge forming processes to replace the production mode. The fabric hinge without the functional area is selected as a raw material, then the fabric hinge is cut or punched, then the fabric hinge is heated and bent, and then the airbag explosion buffer functional area is formed in the injection mould in a sectional glue injection mode. However, the novel inlay injection molding production mode has high requirements on bending of the fabric hinge and the structure of an injection mold.

The traditional bending mechanism of the fabric hinge of the air bag box is simpler, most of the mechanism is of a bending structure, and the requirement on the bending angle is not high. The novel inlay injection molding process has higher requirements on the bending position, bending angle and bending times of the fabric hinge, and the traditional fabric hinge bending device cannot meet the requirements of the novel process.

In summary, the degree of automation of the conventional panel fabric hinge layering and bending is low, and the current inlay injection molding production mode cannot meet the requirements of the conventional object hinge layering and bending.
