[0002] With the continuous development of the automotive industry, consumers are increasingly demanding the comfort, functionality, and safety of car seats. As a critical component affecting ride comfort, the quality and performance of car seat armrests are of great concern. The welded positioning bracket for the armrest shaft is a key component for ensuring accurate and stable installation. It plays a crucial role in securing the armrest shaft and ensuring its flexible rotation and stability at various angles.

[0003] When traditional rigid forming tooling is used to press and weld positioning brackets, due to the lack of a buffer mechanism, excessive pressure at the moment the tooling mold closes and contacts can cause the mold to deform or shift, thereby affecting the forming quality of the workpiece. Summary of the Invention

[0004] The purpose of the present invention is to provide a molding tool and method for a welding positioning bracket for a rotating shaft of an automobile seat armrest, aiming to solve the problem that the existing pressing welding positioning bracket molding tool lacks a buffer mechanism, and excessive pressure at the moment of mold closing contact may cause the mold to deform or displace, thereby affecting the molding quality of the workpiece.

[0005] To achieve the above-mentioned objectives, in the first aspect, the present invention provides a forming tool for a welding positioning bracket of a rotating shaft of an automobile armrest, comprising a processing table, a gantry, a bottom mold, a top mold and a buffer assembly, wherein the gantry is fixedly connected to the processing table and is located on the top of the processing table, the bottom mold is assembled on the top of the processing table, the top mold is arranged on the top of the bottom mold, and the buffer assembly comprises a guide pressure frame, a connecting plate, a buffer rod and a buffer seat; the guide pressure frame is arranged on both sides of the top mold, the connecting plate is assembled on one side of the guide pressure frame, the buffer rod is fixedly connected to the connecting plate and fixedly connected to the processing table, and is located between the processing table and the connecting plate, and the buffer seat is fixedly connected to the processing table and is located on the side of the processing table close to the buffer rod.

[0006] Among them, the guide pressure frame includes a sliding rod and a pressure rod. The sliding rod is fixedly connected to the top mold and is slidably connected to the gantry and is located on both sides of the top mold. The pressure rod is fixedly connected to the sliding rod and is located on the side of the sliding rod close to the gantry.

[0007] Among them, the sliding rod includes a connecting rod, a slider and a reinforcing rib. The connecting rod is fixedly connected to the top mold and is located on both sides of the top mold.

[0008] Wherein, the buffer rod includes a damping rod and a buffer spring. The damping rod is fixedly connected to the connecting plate and the processing table, and is located between the processing table and the connecting plate. The buffer spring is sleeved on the outside of the damping rod.

[0009] Wherein, the buffer seat includes a cushion block and a cushion airbag, the cushion block is fixedly connected to the processing table and is located on the side of the processing table close to the gantry, and the cushion airbag is fixedly connected to the cushion block and is located on the top of the cushion block.

DETAILED DESCRIPTION

[0022] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0023] See also Figures 1 to 3 In the first aspect, the present invention provides a forming tool for a welding positioning bracket of a rotating shaft of an automobile armrest, comprising a processing table 1, a gantry 2, a bottom mold 3, a top mold 4 and a buffer assembly 5, wherein the gantry 2 is fixedly connected to the processing table 1 and is located on the top of the processing table 1, the bottom mold 3 is assembled on the top of the processing table 1, and the top mold 4 is arranged on the top of the bottom mold 3, and the buffer assembly 5 comprises a guide pressure frame 6, a connecting plate 7, a buffer rod 8 and a buffer seat 9; the guide pressure frame 6 is arranged on both sides of the top mold 4, and the connecting plate 7 is assembled on one side of the guide pressure frame 6, the buffer rod 8 is fixedly connected to the connecting plate 7 and fixedly connected to the processing table 1, and is located between the processing table 1 and the connecting plate 7, the buffer seat 9 is fixedly connected to the processing table 1, and is located on the side of the processing table 1 close to the buffer rod 8.

[0024] In the embodiment of the present invention, the processing table 1 provides support and installation conditions for the other mechanisms. The bottom mold 3 and the top mold 4 cooperate with the casting and welding positioning bracket. When the casting and welding positioning bracket is cast, the controller controls the hydraulic mechanism to lower the top mold 4. The top mold 4 moves downward to drive the guide pressing frame 6 to slide on the gantry 2, guide the top mold 4 and drive the connecting plate 7 to move downward at the same time, so as to prevent the top mold 4 from deviating and being unable to close with the bottom mold 3, and also make the connecting plate 7 squeeze the buffer rod 8 and the buffer seat 9, thereby buffering the pressure of the top mold 4, avoiding the bottom mold 3 and the top mold 4 at the moment of closing contact. Excessive pressure may cause deformation or displacement of the mold. After the top mold 4 and the bottom mold 3 are combined to form a closed mold, the feeding mechanism introduces the molten metal solution into the closed mold, cools the metal solution and forms it to produce the welding positioning bracket. Finally, the hydraulic mechanism lifts the top mold 4, opens the mold, and exposes the welding positioning bracket in the bottom mold 3. The worker then demolds and removes the welding positioning bracket, thus completing the molding process of the welding positioning bracket. This solves the problem that the existing pressing welding positioning bracket molding tooling lacks a buffer mechanism, and the mold is in closed contact at the moment of excessive pressure, which may cause the mold to deform or displace, affecting the molding quality of the workpiece.

[0025] Furthermore, the guide pressure frame 6 includes a sliding rod 10 and a pressure rod 11. The sliding rod 10 is fixedly connected to the top mold 4 and is slidably connected to the gantry 2 and is located on both sides of the top mold 4. The pressure rod 11 is fixedly connected to the sliding rod 10 and is located on the side of the sliding rod 10 close to the gantry 2.

[0026] In an embodiment of the present invention, when the hydraulic mechanism drives the top mold 4 to descend, the top mold 4 drives the sliding rods 10 on both sides to move downward together, thereby driving the pressure rod 11 to move downward as well, thereby pushing the connecting plate 7 to squeeze the buffer rod 8 and the buffer seat 9.

[0027] Furthermore, the sliding rod 10 includes a connecting rod 12, a slider 13 and a reinforcing rib 14. The connecting rod 12 is fixedly connected to the top mold 4 and is located on both sides of the top mold 4. The slider 13 is fixedly connected to the connecting rod 12 and is slidingly connected to the gantry 2 and is located between the gantry 2 and the connecting rod 12. The reinforcing rib 14 is fixedly connected to the connecting rod 12 and is located outside the connecting rod 12.

[0028] In an embodiment of the present invention, the connecting rod 12 is used to connect the slider 13 and the top mold 4. When the top mold 4 moves downward, the connecting rod 12 drives the slider 13 to slide on the gantry 2, and the slider 13 slides down, causing the pressure rod 11 to move downward, thereby pushing the connecting plate 7 to squeeze the buffer rod 8 and the buffer seat 9, thereby achieving the purpose of pressure buffering of the top mold 4.

[0029] Furthermore, the buffer rod 8 includes a damping rod 15 and a buffer spring 16. The damping rod 15 is fixedly connected to the connecting plate 7 and fixedly connected to the processing table 1, and is located between the processing table 1 and the connecting plate 7. The buffer spring 16 is sleeved on the outside of the damping rod 15.

[0030] In an embodiment of the present invention, the connecting plate 7 squeezes the damping rod 15 and the buffer spring 16 to buffer the pressure of the top mold 4. The damping rod 15 achieves the purpose of buffering by squeezing the buffer medium therein. The buffer spring 16 further enhances the buffering effect of the damping rod 15 through its own elastic properties.

[0031] Furthermore, the buffer seat 9 includes a cushion block 17 and a cushion airbag 18. The cushion block 17 is fixedly connected to the processing table 1 and is located on the side of the processing table 1 close to the gantry 2. The cushion airbag 18 is fixedly connected to the cushion block 17 and is located on the top of the cushion block 17.

[0032] In the embodiment of the present invention, the cushion block 17 is provided to raise the buffer airbag 18 and shorten the distance between the buffer airbag 18 and the connecting plate 7. The buffer airbag 18 is squeezed and deformed by the connecting plate 7 to achieve buffering of the pressure of the top mold 4.

[0033] Furthermore, the molding tooling of the welding positioning bracket of the automobile seat armrest shaft also includes a cooling box 19, a storage tank 20 and a circulation pipeline 21. The cooling box 19 is assembled on the top of the processing table 1, and the storage tank 20 is fixedly connected to the processing table 1 and is located on one side of the processing table 1. The circulation pipeline 21 is connected to the storage tank 20, the cooling box 19 and the bottom mold 3 respectively.

[0034] In an embodiment of the present invention, the circulation pipeline 21 forms a loop between the bottom mold 3, the cooling tank and the storage tank 20. The storage tank 20 stores coolant that absorbs the heat of the metal solution in the bottom mold 3. The coolant is drawn out of the storage tank 20 through the circulation pipeline 21 and introduced into the bottom mold 3. The heat of the metal solution is absorbed through the heat transfer effect, so that the metal solution is quickly cooled and shaped. The high-temperature coolant is introduced into the cooling box 19 through the circulation pipeline 21 for cooling. After the cooling box 19 detects that the coolant has cooled to a suitable temperature (preset), the circulation pipeline 21 between the cooling box 19 and the storage tank 20 introduces the coolant in the cooling box 19 into the storage tank 20 for storage.

[0037] In an embodiment of the present invention, when the controller controls the hydraulic mechanism to drive the top mold 4 to descend, the top mold 4 drives the connecting rods 12 on both sides to move downward together, thereby driving the slider 13 to slide on the gantry 2, and the slider 13 slides down, causing the pressure rod 11 to move downward, and then pushes the connecting plate 7 to squeeze the buffer rod 8 and the buffer seat 9, so as to achieve the purpose of pressure buffering of the top mold 4. Specifically, the connecting plate 7 squeezes the damping rod 15 and the buffer spring 16 to buffer the pressure of the top mold 4. The damping rod 15 achieves the purpose of buffering by squeezing the buffer medium therein. The buffer spring 16 further enhances the buffering effect of the damping rod 15 through its own elastic properties.
