Description

Technical Field

[0001] This utility model relates to the field of tooling and molds, and in particular to a processing and forming mold for an automobile seat back panel. Background Technology

[0002] Car seats are mainly composed of seat cushion components and backrest components. For each component of a car seat, especially its frame structure, stamping is usually used to form the car seat frame. For example, the back panel of a car seat is usually integrally molded with a corresponding molding die, which allows for modular production. As shown in the Chinese Patent Network, a car seat back panel flanging die (publication announcement number CN218134273U) is used. After the back panel is formed, when unloading, the lower die base is first separated from the upper die base. Then, the hydraulic oil in each cylinder is drawn out by the oil pump. Therefore, the piston of each cylinder will drive the corresponding model block to be drawn into the bottom groove along the corner groove due to the contraction. Thus, the corner of the back panel flanging no longer contacts the model blocks, so that the back panel loses the support and friction of the model blocks, which greatly facilitates the disassembly of the back panel.

[0003] However, there are still some shortcomings in the above-mentioned patented and existing automotive seat back panel processing molds: the existing method of using external power components to assist the seat back panel in separating from the mold to achieve convenient disassembly of the automotive seat back panel is relatively cumbersome and takes a long time to separate, which is not convenient or efficient for the separation and disassembly of the seat back panel. Therefore, those skilled in the art provide an automotive seat back panel processing mold to solve the problems mentioned in the background art. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a processing mold for automotive seat back panels, which solves the problem mentioned in the background art that the existing automotive seat back panel processing molds are inconvenient for unloading after the back panel is formed.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a processing and forming mold for a car seat back panel, comprising a horizontally opposite upper mold frame and a lower mold frame;

[0006] The upper mold frame has an upper template installed on its base frame, and the lower mold frame has a lower template adapted to the upper template installed on its top frame.

[0007] The upper mold frame is equipped with a pressure guide rod at the corner of the frame, and the lower mold frame is equipped with a pressure sleeve at the corner of the frame that is opposite to the pressure guide rod.

[0008] The base frame of the lower mold frame is equipped with a self-ejecting material mechanism;

[0009] The self-ejecting mechanism includes an ejector frame installed below the lower mold frame. An arm-force cross frame is installed inside the frame of the ejector frame, and multiple sets of ejector platforms are arranged on the upper end of the arm-force cross frame. The ejector platforms pass through the lower mold frame and extend into the mold cavity of the lower mold plate. Arm-force vertical frames are provided at both ends of the arm-force cross frame, and pressure-bearing guide rods opposite to the pressure-replacing sleeves are provided at both ends of the arm-force vertical frame.

[0010] As a further technical solution of this utility model: the pressure guide rod, the pressure sleeve, and the pressure-bearing guide rod are perpendicular to each other.

[0011] As a further technical solution of this utility model: the bottom of the mold cavity of the lower template is provided with a telescopic groove that is adapted to the top material platform.

[0012] As a further technical solution of this utility model: multiple sets of arm support rods are arranged inside the frame of the top material rack along the support direction of the arm support frame. The arm support rods pass through the arm support frame, and a compression spring for supporting the arm support frame is sleeved on the outside of the arm of the arm support rod.

[0013] As a further technical solution of this utility model: a first cooler is installed inside the plate frame of the upper mold frame;

[0014] The first cooler includes a first cooling coil inside the built-in upper mold frame. One end of the pipe of the first cooling coil is connected to a first cooling capacity valve port, and the other end of the pipe of the first cooling coil is connected to a first heat capacity valve port. The first cooling coil has a U-shaped coil structure.

[0015] As a further technical solution of this utility model: a second cooler is installed inside the plate frame of the lower mold frame;

[0016] The second cooler includes a second cooling coil inside the built-in lower mold frame. One end of the pipe of the second cooling coil is connected to a second cooling capacity valve port, and the other end of the pipe of the second cooling coil is connected to a second heat capacity valve port. The second cooling coil has a U-shaped coil structure.

[0017] This utility model provides a molding die for processing a car seat back panel, which has the following advantages compared with the prior art:

[0018] 1. The automotive seat back panel forming mold designed in this paper stretches and extrudes the automotive seat back panel based on the alignment of the upper and lower mold plates. While the upper and lower mold plates are aligned, the pressure guide rod slides synchronously along the pressure sleeve, which not only guides the panel but also pushes the ejector plate in the self-ejecting mechanism out of the mold cavity, thus avoiding affecting the forming of the seat back panel. After the seat back panel is formed, when the upper and lower mold plates separate, the ejector plate in the self-ejecting mechanism automatically pushes and resets under the action of elasticity, ejecting the formed seat back panel from the mold. It has good self-ejecting performance and can complete the unloading of the seat back panel without the need for a power component, making the unloading of the seat back panel more convenient and efficient.

[0019] 2. The automotive seat back panel forming mold of this design has a first cooler inside the upper mold frame that is opposite to the upper template and a second cooler inside the lower mold frame that is opposite to the lower template. These coolers can serve as cooling components to reduce the mechanical heat generated by the two sets of templates pressing the seat back panel together, and to compare the thermal fatigue caused by excessive mechanical friction heat.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 This utility model provides a technical solution for processing and forming a mold for a car seat back panel: a mold for processing and forming a car seat back panel includes an upper mold frame 1 and a lower mold frame 2 that are horizontally opposite each other. The upper mold frame 1 is equipped with an upper template 4, and the lower mold frame 2 is equipped with a lower template 5 that is adapted to the upper template 4. By controlling the mutual engagement of the upper template 4 and the lower template 5, the seat back panel is molded.

[0029] The upper mold frame 1 has a pressure guide rod 6 installed at its frame corner, and the lower mold frame 2 has a pressure sleeve 7 installed at its frame corner, which is opposite to the pressure guide rod 6. The pressure guide rod 6, the pressure sleeve 7, and the pressure-bearing guide rod 15 are perpendicular to each other. By setting the pressure guide rod 6, the pressure sleeve 7, and the pressure-bearing guide rod 15 to a perpendicular orientation, when the upper mold plate 4 and the lower mold plate 5 are aligned, the pressure guide rod 6 and the pressure sleeve 7 are synchronously guided and inserted, playing a guiding role and improving the alignment accuracy of the two sets of mold plates. The pressure guide rod 6 acts as a pressure braking component when it is continuously pressed down along the pressure sleeve 7, pressing down the pressure bearing guide rod 15 and pressing the ejector plate 10 out of the mold cavity so that the seat back panel is molded. After the seat back panel is subsequently molded, when the two sets of mold plates open and close, the pressure guide rod 6 moves out of the pressure sleeve 7 and releases the pressure braking of the pressure bearing guide rod 15. Under the elastic reset of the compression spring 12, the ejector plate 10 resets and pushes out the seat back panel automatically.

[0030] The bottom of the mold cavity of the lower mold plate 5 is provided with a telescopic slot 51 that is adapted to the top platen 10. By opening the telescopic slot 51 on the lower mold plate 5 that is adapted to the top platen 10, it serves as a lifting channel for the top platen 10. When the seat back panel is molded, the top platen 10 moves down and is pushed out after molding, pushing the seat back panel in the lower mold plate 5 out from the top.

[0031] The lower mold frame 2 is equipped with a self-ejecting mechanism. This mechanism includes an ejector frame 3 installed below the lower mold frame 2. An arm-force crossbeam 13 is installed inside the frame of the ejector frame 3. Multiple ejector platforms 10 are arranged on the upper end of the support of the arm-force crossbeam 13. The ejector platforms 10 penetrate the lower mold frame 2 and extend into the mold cavity of the lower mold plate 5. Arm-force vertical frames 14 are provided at both ends of the support of the arm-force crossbeam 13, and pressure-bearing guide rods 15, opposite to the pressure-bearing sleeve 7, are provided at both ends of the support of the arm-force vertical frames 14. Multiple sets of arm support rods 11 are arranged inside the frame of 3 along the support direction of the arm support cross frame 13. The arm support rods 11 pass through the arm support cross frame 13, and a compression spring 12 supporting the arm support cross frame 13 is sleeved on the outside of the arm of the arm support rod 11. By utilizing the elastic force combination of the arm support rod 11 and the compression spring 12, the combination of the arm support cross frame 13 and the arm support vertical frame 14 is kept in an elastic compression and reset state. Under the pressure braking of the pressure guide rod 15, the top material platform 10 is pushed to rise and fall, and the seat back panel is pushed out automatically.

[0032] The upper mold frame 1 has a first cooler 8 installed inside the plate frame. The first cooler 8 includes a first cooling coil 81 built into the upper mold frame 1. One end of the pipe of the first cooling coil 81 is connected to a first cooling capacity valve port 82, and the other end of the pipe of the first cooling coil 81 is connected to a first heat valve port 83. The first cooling coil 81 has a U-shaped coil structure. By setting the first cooler 8 inside the upper mold frame 1 as a cooling component, the frictional mechanical heat generated by the upper mold plate 4 due to molding is cooled and reduced to ensure that the processing mold is maintained at a suitable working temperature.

[0033] A second cooler 9 is installed inside the plate frame of the lower mold frame 2. The second cooler 9 includes a second cooling coil 91 built into the lower mold frame 2. One end of the pipe of the second cooling coil 91 is connected to a second cooling capacity valve port 92, and the other end of the pipe of the second cooling coil 91 is connected to a second heat valve port 93. The second cooling coil 91 has a U-shaped coil structure. By setting the second cooler 9 inside the lower mold frame 2 as a cooling component, the frictional mechanical heat generated by the lower mold plate 5 due to molding is cooled and reduced to ensure that the processing mold is maintained at a suitable working temperature.

[0034] The working principle of this utility model is as follows: When processing and molding the back panel of a car seat using a molding die, the upper template 4 and the lower template 5 are controlled to align and mold the back panel. At the same time as molding, the pressure guide rod 6 and the pressure sleeve 7 are synchronously guided and inserted to improve the alignment accuracy of the two sets of templates. When the pressure guide rod 6 is continuously pressed down along the pressure sleeve 7, it acts as a pressure braking component, pressing down the pressure bearing guide rod 15 and pressing the ejector plate 10 out of the mold cavity so that the back panel is molded. After the back panel is molded, when the two sets of templates are opened and closed, the pressure guide rod 6 moves out of the pressure sleeve 7 and releases the pressure braking of the pressure bearing guide rod 15. Using the elastic force combination of the arm support rod 11 and the compression spring 12, the ejector plate 10 on the arm support frame 13 is pushed up and reset, and the back panel is automatically pushed out of the mold cavity. The back panel is automatically ejected and demolded without the need for external force components.

[0035] Furthermore, while molding the seat back panel, the first cooler 8 in the upper mold frame 1 conducts heat to the upper template 4 and the second cooler 9 in the lower mold frame 2 conducts heat to the lower template 5 to cool down the frictional mechanical heat generated by molding. This ensures that the mold is maintained at a suitable working temperature and avoids mechanical thermal fatigue due to excessive heat.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
