Forming mould for air bag baffle

Abstract

A forming mould for an air bag baffle comprises a stationary mould body, a front slide block (2), a rear slide block (3), a left slide block (4) and a right slide block (5). The front slide block (2), the rear slide block (3), the left slide block (4) and the right slide block (5) are arranged on the stationary mould body. One end of each ejector pin (6) is connected inside a first stepped hole (8) in a sliding mode and is positioned on the outer side of a sliding part (42). When the mould is in a closed state, the ejector pins (6) are limited under the action of a movable mould body, and at the same time, the other end of each ejector pin (6) is flush with a product surface of a core-pulling part (41). The other end of each ejector pin (6) is connected inside a second stepped hole (9) in a sliding mode and connected with a first spring (7) in a sleeved mode. An annular protrusion (10) is arranged on each ejector pin (6) and abuts against one end of the corresponding first spring (7). The other end of each first spring (7) abuts against the step surface inside the corresponding second stepped hole (9). An ejector pin mechanism arranged on the right slide block (5) and an ejector pin mechanism arranged on the left slide block (4) are identical in structure. Compared with the prior art, the forming mould for the air bag baffle has the characteristics of being simple in structure, low in cost, good in use stability and high in rate of finished products.

Description

technical field [0001] The invention relates to a mold for forming an airbag baffle for producing an automobile safety airbag baffle. 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 about 1mm, during the dem...

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 easily deformed and causes the breakage at the pre-cut part, so compared with the prior art, 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, and there is no other limit mechanism. 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
