Airbag cover injection mold

Abstract

The invention discloses an airbag cover injection mold. The airbag cover injection mold comprises an upper mold plate (1), a lower mold plate (2), a mold foot (3), a cover plate (4), a sprue (5) and a product (6). The lower mold plate (2) is fixed to the mold foot (3). The upper mold plate (1) is located between the lower mold plate (2) and the cover plate (4). The sprue (5) is arranged on the cover plate (4). An upper mold cavity (6) is arranged on the lower surface of the upper mold plate (1). A lower mold cavity (7) is arranged on the upper surface of the lower mold plate (2). A cavity used for forming the product (6) is arranged between the upper mold cavity (6) and the lower mold cavity (7). An upper mold core (8) used for forming the upper surface of the product (6) is arranged in the upper mold cavity (6). The airbag cover injection mold provided by the invention is low in cost, high in production efficiency and simple in structure, and the product quality is good.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to an injection mold for an airbag cover. Background technique [0002] Automobile airbag system (SRS for short) is an auxiliary safety system, which usually appears as an auxiliary safety device for seat belts, including airbags, storage devices for storing airbags, and airbag covers, among which the airbag cover is important. One of the components, the airbag cover is usually completed by injection molding. After the injection mold is completed, the waste and plastic parts will be connected together. According to the existing technology, after the waste and plastic parts are demoulded at the same time, they will be manually put together. Scraps are cut off, which not only has high labor costs, but also reduces production efficiency; another is to break the point gate between the waste and plastic parts through the cavity plate after the injection molding mold of the plastic parts is...

Problems solved by technology

[0002] Automobile airbag system (SRS for short) is an auxiliary safety system, which usually appears as an auxiliary safety device for seat belts, including airbags, storage devices for storing airbags, and airbag covers, among which the airbag cover is important. One of the parts, the airbag cover is usually completed by injection molding. After the injection mold is completed, its waste and plastic parts will be connected together. Scraps are cut off, which not only has high labor costs, but also reduces production efficiency; there is another method that after the injection molding mold of plastic parts is opened, the point gate between the waste and plastic parts is broken through the cavity plate, and the broken gate is broken. The plastic parts are pushed out by the pusher plate through the thimble, and fall into the collection box. A special ejection mechanism needs to be set up, and the structure is cumbersome. At the same time, it is injected through a sprue during injection molding, and the product quality is poor.
