Airbag plastic mould

Abstract

The invention provides an airbag plastic mould in which junctures of a lifter and a product as well as a moving core are less prone to generation of flash and the product is less prone to falling when ejected out. The airbag plastic mould comprises a fixed core (1), the moving core (2) and a product cavity (3) positioned between the fixed core and the moving core, the lifter (4), a right slider (6) and a left slider (7) are connected onto the product cavity (3) respectively, the lifter (4) is in sliding sleeved fit with the moving core (2), and one side of the upper end of the lifter (4) is directly connected with the product cavity (3) while the other side of the same is attached to the moving core (2). The airbag plastic mould is characterized in that a reverse button (9) is arranged on one side, attached to the moving core (2), of the lifter (4), a button buttoned with the reverse button (9) is arranged on the moving core (2), an anti-falling needle (5) is further connected onto the product cavity (3), and saw teeth (10) are arranged at a contacting position of the side face of the anti-falling needle (5) and the product cavity (3).

Description

Technical field [0001] The invention relates to a plastic mold for an airbag. Background technique [0002] In the prior art, plastic molds for airbags include fixed mold cores, movable mold cores, inclined roofs, sliders and other necessary components. However, due to the complex structure of the airbag products, the reliability and design requirements of the inclined roof and the slider are relatively high. The inclined roof structure used for the airbag in the prior art adopts the structure most commonly used by technicians in the industry, and is mainly made of an inclined rod with a smooth appearance. When this structure is used in airbag plastic molds, the inclined roof is generally designed to be relatively large. One side of the inclined roof is the product, and the other side is the movable mold core. After the product is formed, the inclined top pushes the product upwards out of the movable mold core. After the worker or an automatic picking mechanism removes the mold...

AI Technical Summary

Problems solved by technology

Due to the large body of the inclined ejector, it is easy to produce a gap between the wall of the inclined ejector socket on the movable mold core during the retraction process. This gap makes the inclined ejector, the movable mold core and the product common Flashing is easy to appear at the junction, which affects the use of the product

In addition, due to the limitation of the structure, the inclined roof can only be pushed on one side of the product. When the product is pushed out of the mold core by the inclined roof, the product is easy to fall from the inclined roof due to the inertia force, which is not convenient for automatic removal. Material mechanism for reclaiming operation

To sum up, the plastic molds for airbags in the prior art have the disadvantages that the joint between the inclined roof and the product and the moving mold core is prone to flash, and the product is easy to fall when it is ejected.
