Automobile safety airbag cover ejection mechanism

Abstract

The invention discloses an automobile safety airbag cover ejection mechanism. The automobile safety airbag cover ejection mechanism comprises an upper die, a lower die, a support block and a bottom plate, the support block is located between the lower die and the bottom plate, the lower die is provided with sliding blocks used for forming a first undercut of the side face of a product and a secondundercut of the lower surface of the product and a die core used for forming the lower surface of the other part of the product correspondingly, the automobile safety airbag cover ejection mechanismfurther comprises an ejector pin plate, the ejector pin plate is located between the bottom plate and the lower die, the sliding blocks comprise the first sliding block and the second sliding block, the first sliding block is located on the second sliding block, the first sliding block is matched on the second sliding block through an inclined face, the second sliding block is matched on the uppersurface of the lower die in a sliding mode, the first sliding block is used for forming the first undercut and the second undercut, a first-time ejection mechanism is arranged between the bottom plate and the first sliding block, and a second-time ejection mechanism is arranged between the die core and the ejector pin plate. The automobile safety airbag cover ejection mechanism has the advantagesthat the reliability is high, and the rejection rate is low.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to an automobile safety airbag cover ejection mechanism. Background technique [0002] The car airbag cover is one of the important parts of the car. The car airbag cover is injection molded through an injection mold. The side of the car airbag cover is provided with an undercut, which is formed by using the side of the slider. Ribs and undercuts, if the ejector mechanism is not arranged, it will be difficult to demould the product. According to the existing technology, when the mold is opened, the inclined guide column is used to cooperate with the slider to realize the core pulling of the slider, and the slider performs undercut on the side of the product. Core-pulling, conventional ejector mechanism is designed to eject the deep ribs and undercuts on the bottom surface of the automobile airbag cover. When the ejector mechanism ejects, it will interfere with the slider, which is eas...

Core-pulling, conventional ejector mechanism is designed to eject the deep ribs and undercuts on the bottom surface of the automobile airbag cover. When the ejector mechanism ejects, it will interfere with the slider, which is easy to damage the product, low reliability, and high scrap rate
