[0001] This utility model relates to the field of molding tooling technology, and in particular to a molding tooling for a welding positioning bracket of an automotive seat armrest pivot. Background Technology

[0002] With the continuous development of the automotive industry, consumers have increasingly higher requirements for the comfort, functionality, and safety of car seats. As a crucial component affecting seating comfort, the quality and performance of car seat armrests are of great concern. The welded positioning bracket for the armrest pivot is a key component ensuring the installation accuracy and stability of the armrest pivot. This bracket plays a vital role in fixing the armrest pivot and ensuring its flexible rotation and stability at different angles.

[0003] When traditional rigid forming fixtures are used to press and weld positioning brackets, the lack of a buffer mechanism can cause excessive pressure on the fixture mold at the moment of closing contact, which can lead to mold deformation or displacement and thus affect the forming quality of the workpiece. Utility Model Content

[0004] The purpose of this utility model is to provide a forming fixture for a welding positioning bracket of an automotive seat armrest pivot, which aims to solve the problem that the existing pressing welding positioning bracket forming fixture lacks a buffer mechanism, and that excessive pressure at the moment of mold closing contact can cause mold deformation or displacement, affecting the forming quality of the workpiece.

[0005] To achieve the above objectives, in a first aspect, this utility model provides a forming fixture for a welding positioning bracket of an automotive seat armrest pivot, comprising a processing table, a gantry frame, a bottom mold, a top mold, and a buffer assembly. The gantry frame is fixedly connected to the processing table and located on top of the processing table. The bottom mold is assembled on top of the processing table, and the top mold is disposed on top of the bottom mold. The buffer assembly includes a guide pressure frame, a connecting plate, a buffer rod, and a buffer seat. The guide pressure frame is disposed 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 to the processing table, and is located between the processing table and the connecting plate. The buffer seat is fixedly connected to the processing table and is located on the side of the processing table closer to the buffer rod.

[0006] The guide frame includes a sliding rod and a pressure rod. The sliding rod is fixedly connected to the top mold and slidably connected to the gantry frame, 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 closer to the gantry frame.

[0007] The sliding rod includes a connecting rod, a slider, and a reinforcing rib. The connecting rod is fixedly connected to the top mold and located on both sides of the top mold. The slider is fixedly connected to the connecting rod and slidably connected to the gantry frame and located between the gantry frame and the connecting rod. The reinforcing rib is fixedly connected to the connecting rod and located outside the connecting rod.

[0008] 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] The buffer seat includes a pad and a buffer airbag. The pad is fixedly connected to the processing table and is located on the side of the processing table near the gantry frame. The buffer airbag is fixedly connected to the pad and is located on top of the pad.

[0010] The forming fixture for the welding positioning bracket of the car seat armrest pivot also includes a cooling box, a storage tank and a circulation pipeline. The cooling box is mounted on the top of the processing table, the storage tank is fixedly connected to the processing table and located on one side of the processing table, and the circulation pipeline is connected to the storage tank, the cooling box and the bottom mold respectively.

[0011] Secondly, this utility model also provides a method for forming a welding positioning bracket for a car seat armrest pivot, which is applied to the forming fixture for the welding positioning bracket for a car seat armrest pivot as described in the first aspect above, and includes the following steps;

[0012] The controller controls the hydraulic mechanism to lower the top mold, which is then buffered by the buffer rod and buffer seat until the top mold and bottom mold are closed.

[0013] The feeding mechanism introduces molten metal solution into the closed mold, and the coolant in the cooling tank is introduced into the bottom mold through the circulation pipeline to cool and form the welding positioning bracket.

[0014] The hydraulic mechanism lifts the top mold, opens the mold to expose the welding positioning bracket inside the bottom mold, and then the worker removes the welding positioning bracket from the mold.

[0015] This utility model discloses a forming fixture for a welding positioning bracket of an automotive seat armrest pivot. The processing table provides support and installation conditions for the other mechanisms. The bottom mold and the top mold cooperate to cast the welding positioning bracket. During the casting and welding of the positioning bracket, the controller controls the hydraulic mechanism to lower the top mold. The downward movement of the top mold causes the guide pressure frame to slide on the gantry frame, guiding the top mold and simultaneously driving the connecting plate downward. This prevents the top mold from shifting and failing to close with the bottom mold, and also causes the connecting plate to press against the buffer rod and the buffer seat, thereby buffering the pressure on the top mold and preventing the bottom mold and top mold from closing prematurely. At the moment of contact, excessive pressure can cause mold deformation or displacement. After the top mold and bottom mold close to form a closed mold, the feeding mechanism introduces molten metal solution into the closed mold, cools and solidifies the molten metal solution to produce the welded positioning bracket. Finally, the hydraulic mechanism lifts the top mold, opens the mold, and exposes the welded positioning bracket inside the bottom mold. The worker then demolds and removes the welded positioning bracket, thus completing the forming process of the welded positioning bracket. This solves the problem that existing pressing welding positioning bracket forming tooling lacks a buffer mechanism, and excessive pressure at the moment of mold closure can cause mold deformation or displacement, affecting the forming quality of the workpiece.

Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] Please see Figures 1 to 3 In a first aspect, this utility model provides a forming fixture for a welding positioning bracket of an automotive seat armrest pivot, including a processing table 1, a gantry frame 2, a bottom mold 3, a top mold 4, and a buffer assembly 5. The gantry frame 2 is fixedly connected to the processing table 1 and located on top of the processing table 1. The bottom mold 3 is assembled on top of the processing table 1, and the top mold 4 is disposed on top of the bottom mold 3. The buffer assembly 5 includes a guide pressure frame 6, a connecting plate 7, a buffer rod 8, and a buffer seat 9. The guide pressure frame 6 is disposed on both sides of the top mold 4, 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 processing table 1 near the buffer rod 8.

[0024] In this embodiment of the utility model, the processing table 1 provides support and installation conditions for the other mechanisms. The bottom mold 3 and the top mold 4 cooperate to cast and weld a positioning bracket. When casting and welding the positioning bracket, the controller controls the hydraulic mechanism to lower the top mold 4. The downward movement of the top mold 4 drives the guide pressure frame 6 to slide on the gantry frame 2, guiding the top mold 4 and simultaneously driving the connecting plate 7 to move downward, preventing the top mold 4 from shifting and failing to close with the bottom mold 3. This also causes the connecting plate 7 to press the buffer rod 8 and the buffer seat 9, thereby buffering the pressure on the top mold 4 and preventing the bottom mold 3 and the top mold 4 from closing at the moment of contact. Excessive pressure can cause mold deformation or displacement. After the top mold 4 and the bottom mold 3 are closed to form a closed mold, the feeding mechanism introduces molten metal solution into the closed mold, cools and solidifies the metal solution 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 forming process of the welding positioning bracket. This solves the problem that the existing pressing welding positioning bracket forming tooling lacks a buffer mechanism, and that excessive pressure at the moment of mold closure can cause mold deformation or displacement, affecting the forming 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 slidably connected to the gantry frame 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 closer to the gantry frame 2.

[0026] In this embodiment of the utility model, 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 down together, thereby driving the pressure rod 11 to move down 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 slidably connected to the gantry frame 2 and is located between the gantry frame 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 this embodiment of the utility model, the connecting rod 12 is used to connect the slider 13 and the top mold 4. When the top mold 4 moves down, the connecting rod 12 drives the slider 13 to slide on the gantry 2. The slider 13 slides down, causing the pressure rod 11 to move down, thereby pushing the connecting plate 7 to squeeze the buffer rod 8 and the buffer seat 9, so as to achieve the purpose of buffering the pressure 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 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 this embodiment of the present invention, the connecting plate 7 presses 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 pressing the buffer medium therein, and 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 pad 17 and a buffer airbag 18. The pad 17 is fixedly connected to the processing table 1 and is located on the side of the processing table 1 near the gantry frame 2. The buffer airbag 18 is fixedly connected to the pad 17 and is located on top of the pad 17.

[0032] In this embodiment of the utility model, the pad 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 deformed by the connecting plate 7 to buffer the pressure of the top mold 4.

[0033] Furthermore, the forming fixture for the welding positioning bracket of the car seat armrest pivot also includes a cooling box 19, a storage tank 20, and a circulation pipe 21. The cooling box 19 is mounted on the top of the processing table 1, the storage tank 20 is fixedly connected to the processing table 1 and located on one side of the processing table 1, and the circulation pipe 21 is connected to the storage tank 20, the cooling box 19, and the bottom mold 3 respectively.

[0034] In this embodiment of the invention, the circulation pipe 21 forms a loop between the bottom mold 3, the cooling tank, and the storage tank 20. The storage tank 20 stores a coolant that absorbs heat from the molten metal in the bottom mold 3. The coolant is drawn out of the storage tank 20 through the circulation pipe 21 and introduced into the bottom mold 3. Through the heat transfer effect, it absorbs heat from the molten metal, causing the molten metal to cool and solidify rapidly. The high-temperature coolant is introduced into the cooling box 19 through the circulation pipe 21 for cooling. After the cooling box 19 detects that the coolant has cooled to a suitable temperature (preset), the circulation pipe 21 between the cooling box 19 and the storage tank 20 introduces the coolant from the cooling box 19 into the storage tank 20 for storage.

[0035] Please see Figure 4Secondly, this utility model also provides a method for forming a welding positioning bracket for a car seat armrest pivot, which is applied to the forming fixture for the welding positioning bracket for a car seat armrest pivot as described in the first aspect above, and includes the following steps;

[0036] The S1 controller controls the hydraulic mechanism to lower the top mold 4, which is then buffered by the buffer rod 8 and the buffer seat 9 until the top mold 4 and the bottom mold 3 are closed.

[0037] In this embodiment of the utility model, 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 down together, thereby driving the slider 13 to slide on the gantry frame 2. 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, achieving the purpose of buffering the pressure 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. The buffer airbag 18 is deformed by the compression of the connecting plate 7 to achieve the buffering of the pressure of the top mold 4.

[0038] The S2 feeding mechanism introduces molten metal solution into the closed mold, and the coolant in the cooling box 19 is introduced into the bottom mold 3 through the circulation pipe 21 to cool and form the welding positioning bracket.

[0039] In this embodiment of the invention, the coolant is drawn out of the storage tank 20 through the circulation pipeline 21 and introduced into the bottom mold 3. Through the heat transfer effect, the coolant absorbs the heat of the metal solution, so that the metal solution is quickly cooled and shaped to produce the welding positioning bracket.

[0040] The S3 hydraulic mechanism lifts the top mold 4, opens the mold to expose the welding positioning bracket inside the bottom mold 3, and then the worker removes the welding positioning bracket from the mold.

[0041] The above-disclosed embodiments are merely preferred embodiments of the forming tooling for the welding positioning bracket of the car seat armrest pivot of this utility model. Of course, they should not be construed as limiting the scope of this utility model.
