Description

Technical Field

[0001] The utility model relates to the technical field of safety airbag generators, in particular to a housing molding device for a safety airbag generator. Background Art

[0002] Airbag generator is an important part of automobile safety system. Its main function is to inflate airbag quickly when the vehicle collides, so as to protect passengers from injury. Definition and location: Airbag generator is a device located inside the airbag, which is used to generate gas to fill the airbag when a collision occurs. It usually works with the airbag system, including sensors, microprocessors and other components. Working principle: When the vehicle collides, the sensor will detect the collision signal and transmit it to the microprocessor. After the microprocessor analyzes the signal, if the conditions for airbag deployment are met, it will send an ignition command to the gas generator. The gas generator will then ignite the solid fuel, generate gas and quickly inflate the airbag. Function: The airbag generator can effectively prevent passengers from directly colliding with parts inside the car during a collision, thereby reducing injuries. It is used in conjunction with seat belts to provide more comprehensive protection for passengers. In short, airbag generator is an important equipment in the automobile safety system and is of great significance to ensuring passenger safety.

[0003] The processing of the airbag generator housing requires a mold. After the existing mold is processed, the user usually needs to manually remove it. At the same time, the housing is tightly attached to the surface of the mold. Manual removal is time-consuming and laborious, which increases the labor intensity of use and reduces the efficiency of mold use. To this end, we propose a molding device for the airbag generator housing. Utility Model Content

[0032] The limiting mechanism 4 is fixedly mounted at the four corners of the bottom of the pressing plate 2 and is used for quickly resetting the pressing plate 2 .

[0033] The tightening mechanism 3 includes a motor 301, the output end of the motor 301 is meshed with a chain 303 through a sprocket 302, one end of the chain 303 away from the motor 301 is movably connected to a bidirectional screw 304 through the sprocket 302, and both sides of the surface of the bidirectional screw 304 are movably connected to a screw sleeve 305. The rotation of the motor 301 drives the bidirectional screw 304 to rotate, thereby driving the screw sleeve 305 to move to both sides.

[0034] The outer side of the screw sleeve 305 is fixedly connected to the first trapezoidal block 306, the outer side of the first trapezoidal block 306 is movably connected to the second trapezoidal block 307, the top of the second trapezoidal block 307 is fixedly connected to the vertical rod 308, and the top of the vertical rod 308 is fixedly connected to the bottom of the abutting plate 2. The screw sleeve 305 drives the first trapezoidal block 306 to move to both sides so that the second trapezoidal block 307 is forced to move toward the top, driving the vertical rod 308 to move toward the top, thereby driving the abutting plate 2 to move toward the top.

[0035] Stable bearings 309 are fixedly installed on both sides of the surface of the bidirectional screw 304, and a support plate 310 is fixedly connected to the outer side of the stable bearing 309, and the bottom of the support plate 310 is fixedly connected to the bottom of the inner wall of the mold body 1. The stable bearing 309 and the support plate 310 support the bidirectional screw 304 to improve the stability of the rotation of the bidirectional screw 304.
