It not only provides a comfortable riding experience for passengers but also ensures the safety of passengers during driving. From a design perspective, an automobile seat needs to consider ergonomics to adapt to passengers of different body sizes and provide good support and comfort. For example, the shape and curvature of the seat should fit the spinal curve of the human body to reduce the fatigue of long-term sitting. At the same time, the height, angle of the seat, and the position of the headrest can all be adjusted to meet the personalized needs of passengers. During the production and processing of automobile seats, foam molds are required to manufacture the backrest and seat cushion. The prepared foam material is injected into the mold and foamed and formed under certain temperature, pressure, and time conditions. After the foaming is completed and cooled, the upper mold is opened, and the formed seat cushion is removed from the lower mold.

The utility model sets a quick disassembly and assembly mechanism at the bottom of the lower die base. When pushing the fastener, the fastener drives the connecting seat to move, so that the fastener advances the rack into the inner side of the chute through the connecting seat. When the rack slides into the chute, it drives the gear to rotate, so that the gear drives the other rack to be retracted into the inner side of the chute, thereby fixing the lower die base and the pressing plate by the left fastener. The disassembly and assembly are fast, which provides convenience for users. By setting a locking mechanism inside the card slot, by holding the rotating handle and rotating it, the rotating handle drives the threaded rod to rotate, so that the threaded rod screws into the inner side of the threaded groove, thereby fixing the fastener and making the fastener not easy to loosen during use.
