Description

Technical Field

[0001] The utility model relates to the technical field of oblique wedge moulds, in particular to a mould for processing and forming a back plate of an automobile seat. Background Art

[0002] Car seat back panel products are a type of car accessories. When producing back panel negative angle products, a mold with a rotating bevel is used to cast the product, and then a complete finished product can be manufactured after subsequent polishing. However, in actual production, the cylinder of the equipment will vibrate during operation. With long-term shaking, the stability of the cylinder will gradually weaken, so that the cylinder cannot work normally, which will affect the normal use of the equipment. Therefore, it is necessary to improve the shortcomings of the existing equipment during use. To this end, there is a public technology on the market that discloses a car seat back panel processing and molding mold (Chinese Patent Publication No. CN218168432U), including: a body, a cylinder and a connecting pipe, a power mechanism is arranged on one side of the body; one end of the power mechanism is connected to the air inlet on the body, a linkage arm is also installed on one side of the body, an upper mold drive block is respectively installed at both ends of the body, a rotating shaft is arranged on one side of the upper mold drive block, and a first slider is also installed inside the body. When the cylinder is in use, first align one end of the two screw rods with the corresponding inner ring of the bearing, then rotate the screw rod to move the screw rod from the inside of the threaded sleeve to the outside, and finally insert one end of the screw rod into the inner ring of the bearing, so that the screw rod and the threaded sleeve can be supported between the two cylinders, and the mounting seat is fixed on the ground. In summary, this structure can be used to perform secondary reinforcement between the two cylinders during use to reduce the vibration amplitude of the cylinder when in use;

[0003] However, during the pushing process, the end of the linkage arm connected to the end of the cylinder extension shaft has a rotating movement along the connection point between the linkage arm and the mold, that is, the cylinder needs to be movable and cannot be fixed to the ground. The usual practice is to connect the end of the cylinder away from the extension shaft to the equipment through a rotating seat. In the above-mentioned public technology, the end of the cylinder away from the extension shaft is connected to the equipment through a rotating seat, and is supported between the two cylinders by a screw and a threaded sleeve and fixed to the ground through a mounting seat, which makes the cylinder unable to rotate with the linkage arm, resulting in jamming. Even if it is not fixed to the ground, it is supported between the two cylinders by a screw, and the actual reinforcement effect is very limited. Therefore, it is necessary to improve and optimize the structure of the mold for processing and forming the back panel of the automobile seat to improve the stability of the cylinder movement.
