A four-time ejection mechanism for an airbag

Abstract

A four-time ejection mechanism for an airbag is characterized in that: the mold core includes a first mold core, a second mold core and a third mold core, and a second movable plate, a third The third movable plate, the fourth movable plate, and the fourth ejection mechanism, the upper fixed plate is provided with inclined core pulling, the straight rod section of the inclined core pulling is fixed with the upper fixed plate, and the inclined section extends into the product through the die base The second movable plate is provided with a sloping top, one end of the sloping top is hinged with the second movable plate, and the other end passes through the first movable plate in turn. The three mold cores and the second mold core are matched with the first hollow on the inner skirt that is blocked by the outer skirt and the third inversion at the root of the cover plate. The first movable plate, the second movable plate, the third movable plate And the fourth movable plate is connected with the four ejection mechanism. The four-time ejection mechanism of the airbag is simple in structure and convenient in operation.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a four-time ejection mechanism of an airbag. Background technique [0002] The structure of an existing airbag is as follows figure 1 As shown, it includes a casing, the casing includes a cover plate 1a and a skirt protruding upward along the cover plate 1a, the skirt includes an inner skirt 2a and an outer skirt 3a, and the outer skirt 3a is wavy The outer side wall of the inner skirt 2a is provided with a number of first inversions 4a, the inner side wall of the inner skirt 3a is also provided with a number of second inversions 5a, and the inner skirt 2a is also provided with a number of In the first hollow 6a, the inner side wall of the cover plate 1a is provided with a plurality of third undercuts 7a at the root, and the top of the cover plate 1a is provided with a plurality of second hollows 8a and fourth undercuts 9a. From the structure, it can be seen that the inner skirt ...

AI Technical Summary

Problems solved by technology

At present, the first hollow 6a on the product that is not blocked by the outer skirt 3a is generally realized by setting an undercut structure on the slider. When the mold is opened, the slider moves synchronously to make the corresponding hollow and slider The undercut is detached, but for the hollows blocked by the outer skirt 3a and the undercuts in a narrow space, it is currently necessary to design a very complicated structure to completely release the product, and the operation is also very inconvenient
