Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] Such as Figure 1-4 As shown, the airbag mold provided in this embodiment has a positioning hole 110 in the center of the mold upper cover 100. After the positioning rod 310 of the mold core 300 passes through the positioning hole 110, the mold upper cover 100 carries the mold core 300 and the mold base. 200 assembly, with the assembly of the mold upper cover 100 and the mold base 200, the inner core 320 of the mold core 300 will enter the mold cavity 210, and the inner core 320 cooperates with the mold cavity 210 to form an airbag molding cavity; the mold cavity 210 Rubber or silica gel is poured into the airbag in advance, so the process of the inner core 320 entering the mold cavity 210 is the process of forming the airbag.

[0039] Since the inner core 320 cooperates with the mold cavity 210 to form an airbag molding cavity, it is ...

Abstract

The invention discloses an air bag mold. The air bag mold comprises a mold upper cover and a mold base, wherein a positioning hole is formed in the center of the mold upper cover, the mold base is provided with a mold cavity, the air bag mold further comprises a mold core, the mold core comprises an inner core and a positioning rod capable of penetrating through the positioning hole, and the inner core is used for being matched with the mold cavity to form an air bag forming cavity. According to the air bag mold, the positioning hole is formed in the mold upper cover, the mold core is composed of the inner core and the positioning rod, the positioning rod penetrates through the positioning hole to fix the position of the mold core, and the purposes that the positioning structure of the mold is simplified, the air bag manufacturing steps are simplified, and the air bag manufacturing efficiency is improved are achieved; and meanwhile, air holes which penetrate through the upper mold cover and communicate with the mold cavity is formed in the upper mold cover, so that redundant silica gel or rubber can leak out from the air holes, silica gel or rubber subjected to secondary casting can enter the mold cavity from the air holes, and the purposes of reducing the difficulty of manufacturing an air bag and increasing the success rate of manufacturing the air bag are achieved.

Description

technical field [0001] The invention relates to the field of mold design, in particular to an airbag mold for making airbags. Background technique [0002] The airbag is an elastic component that is filled with a medium in a flexible capsule and uses the compressibility or fluidity of the medium to achieve elastic action. [0003] The airbag can not only be used as an auxiliary device for the passive safety of the body, but also in the field of soft robots, the airbag can be combined with the embedded skeleton to change the rigidity of the soft robot, so the airbag has a very wide application prospect, and the airbag mold used to make the airbag has a great impact on the airbag. The production success rate plays a decisive role. [0004] Existing air bag moulds, such as a kind of air bag mold disclosed in the Chinese patent whose publication number is CN110667121A and an air bag manufacturing method, include an upper air bag mold and a lower air bag mold, the upper air bag ...
