High-efficiency forming device for airbag baffle

Abstract

The invention discloses an efficient forming device of a safety airbag baffle plate. The device comprises a fixed mold (25), and a front slide block (2), a back slide block (3), a left slide block (4) and a right slide block (5) arranged on the fixed mold (25); at least two thimble mechanisms are respectively arranged on the left slide block (4) and the right slide block (5); the thimble mechanisms include thimbles (6) and first springs (7); one ends of the first springs (7) are butted against annular projections (10), and the other ends of the first springs (7) are butted against step surfaces in second step holes (9); the thimble mechanisms on the right slide block (5) are the same with the thimble mechanisms on the right slide block (4) in structure; and a parting line between the front slide block (2) and the fixed mold (25) is positioned on a transverse reinforcing rib at the lowermost side of a front side plate of the safety airbag baffle plate. Compared with the prior art, the device has the characteristics of relatively simpler structure, relatively lower cost, better use stability and higher yield.

Description

technical field [0001] The invention relates to a high-efficiency forming device for safety airbag baffles used for producing automobile safety airbag baffles. Background technique [0002] At present, the automobile airbag is installed on the automobile instrument beam, and the connection bracket of the airbag needs to be installed at the connection part of the automobile instrument beam and the automobile airbag to ensure the stable connection between the automobile airbag and the automobile instrument beam. Therefore, the automobile airbag bracket lifespan is crucial. [0003] The airbag panel of the automobile airbag includes the outer frame of the airbag and the inner frame of the airbag, but the structure of the injection mold of the existing automobile airbag baffle is generally complicated and difficult to operate, and the connection between the inner frame of the airbag and the outer frame of the airbag has a pre-determined structure , the smaller size is generally...

Problems solved by technology

[0006] After adopting the above structure, compared with the prior art, since the present invention is equipped with ejector mechanism on the left slider and the right slider, in the process of core pulling, since the ejector pin is relatively fixed relative to the product at the beginning Yes, the core-pulling block moves first, and the top has a pressing effect on the side of the product, so that the side of the product remains still when the core-pulling block is disengaged from the product surface, and the core-pulling block moves a certain distance before driving The thimble moves together to complete the complete core-pulling, thereby ensuring that the corresponding pre-breaking position is not easy to break during the core-pulling process. The thimble pushes against the reinforcing rib, compared to the product surface between the reinforcing ribs, and pushes against the reinforcing rib. The stability of the product on the top is relatively low, and once it is pushed against the product surface between the ribs, because the thimble is relatively small, the product is still easy to deform when the core is pulled, causing the pre-breaking part to break, and if the thimble is replaced by a top block On the product surface between the reinforcing ribs, and because the height of the reinforcing ribs on the left and right sides is relatively high, the friction when the top block is disengaged is relatively large, and the top block is driven to move together after the core-pulling block is disengaged from the product. At the same time, the product is also easy to deform and cause the breakage of the pre-cut part, so compared with the existing technology, the yield can be increased by more than 30%; and the position of the thimble of the thimble mechanism is guaranteed by the spring and the movable mold, there is no other limit mechanism, and the There is no other auxiliary mechanism, the overall structure is relatively simple, and the structure of the parts is also relatively simple, which is a purely mechanical structure, so the preparation cost is relatively low, and the use stability is also good; the parting between the front slider and the fixed mold The line is located at the lowermost horizontal rib on the front side panel of the airbag baffle. After this setting, when the front slider core is pulled, the fixed mold has a limit effect on the product, and the product is easier to disengage from the front slider. Open, and the product is not easy to be deformed during the core-pulling process of the front slider, so as to ensure the stability of each pre-cut part of the product and further improve the success rate of demoulding
