Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive instrument panel welding plate production technology, specifically to an automotive instrument panel welding plate forming mold. Background Technology
[0002] In the automotive manufacturing industry, the quality of automotive instrument panel welding plates, as important interior components, directly affects the overall performance and interior quality of a vehicle. The forming quality of automotive instrument panel welding plates largely depends on the design and performance of the forming molds.
[0003] However, some molds lack effective demolding aids, requiring manual removal of the welded plate from the mold using tools after molding. This method is not only inefficient, increasing production cycles and labor costs, but also prone to damaging the welded plate during operation, leading to defects such as scratches and deformation on the product surface, affecting the product's appearance and dimensional accuracy, and reducing the yield rate. On the other hand, some molds, although designed with simple demolding structures, suffer from poor stability. During the molding process, various components of the mold may shift due to external forces or their own vibrations, thus affecting the molding quality of the welded plate. Therefore, a new automotive instrument panel welding plate molding mold is proposed to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a molding die for an automotive instrument panel welding plate, which solves the problem that the molding die is displaced due to external forces or its own vibration during the forming process, thus affecting the forming quality of the welding plate.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A molding die for forming an automotive instrument panel welding plate includes a base and a top frame disposed on the base. The molding die further includes a lower mold fixedly connected to the top of the base, a cylinder fixedly connected to the inner top wall of the top frame, an upper mold fixedly connected to one end of the piston rod of the cylinder, and a demolding assembly disposed inside the base. The demolding assembly includes four elastic telescopic members fixedly connected to the inner bottom wall of the base, a frame fixedly connected to the top of the elastic telescopic members, four push rods fixedly connected to the top of the frame, and a top template fixedly connected to the top of the four push rods. The automotive instrument panel welding plate forming mold also includes a locking structure for locking the frame to restrict the up-and-down movement of the frame. The locking structure includes a rotating rod rotatably connected to the inner top wall of the frame, a transmission gear fixedly connected to the outside of the rotating rod, a driven gear meshing with the transmission gear, a threaded rod fixedly connected to the inside of the driven gear, a threaded block threadedly connected to the outside of the threaded rod, a locking rod fixedly connected to the threaded block, and a support plate fixedly connected between the inner top wall and the inner bottom wall of the base. The inner side of the support plate has a locking hole adapted to the locking rod.
[0006] Furthermore, the four elastic telescopic members are respectively arranged at the four corners of the bottom of the frame, and the four top rods are respectively arranged at the four corners of the top of the frame.
[0007] Furthermore, the number of driven gears is set to two, the two driven gears are located on the left and right sides of the transmission gear, and the two driven gears mesh with the transmission gear respectively. The threaded rod is fixedly connected to the inner side of each driven gear, and the threaded block is threadedly connected to the end of each threaded rod away from the driven gear. Locking rods are fixedly connected to the opposite sidewalls of the threaded blocks on the left and right sides.
[0008] Furthermore, the number of support plates is two, and the two support plates are respectively located on the left and right sides of the frame, and each support plate has a locking hole on its inner side that is compatible with the locking rod.
[0009] Furthermore, a torsion cap is fixedly connected to the bottom end of the rotating rod, and both the transmission gear and the driven gear are bevel gears.
[0010] Furthermore, the end of each threaded rod that is away from the driven gear is rotatably connected to the inner sidewall of the frame.
[0011] Furthermore, each of the threaded blocks is provided with four locking rods, which are respectively arranged at the four corners of the corresponding threaded block.
[0012] Compared with the prior art, this utility model provides a molding die for forming an automotive instrument panel welding plate, which has the following beneficial effects: This automotive instrument panel welding plate forming mold, during the forming process, uses a rotating rod to drive the transmission gear and driven gear, causing the threaded rod to move the threaded block, which in turn inserts the locking rod into the locking hole of the support plate, restricting the vertical movement of the frame. This locking mechanism ensures the stability of the mold during the welding plate forming process, preventing displacement of mold components due to external forces or vibrations, and effectively improving the forming quality of the welding plate. After unlocking, the elastic telescopic component automatically extends upward, pushing the frame, ejector rod, and top template upward, thereby enabling the formed welding plate to be quickly ejected from the lower mold, which helps improve the demolding efficiency of the welding plate.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1 to 3 The automotive instrument panel welding plate forming mold in this embodiment includes a base 1 and a top frame 2 disposed on the base 1. The automotive instrument panel welding plate forming mold also includes a lower mold 3 fixedly connected to the top of the base 1, a cylinder 4 fixedly connected to the inner top wall of the top frame 2, an upper mold 5 fixedly connected to one end of the piston rod of the cylinder 4, and a demolding assembly disposed inside the base 1. The demolding assembly includes four elastic telescopic members 6 fixedly connected to the inner bottom wall of the base 1, a frame 7 fixedly connected to the top of the elastic telescopic members 6, four push rods 8 fixedly connected to the top of the frame 7, and a top template 9 fixedly connected to the top of the four push rods 8.
[0017] Please see Figure 1In this embodiment, the automotive instrument panel welding plate forming mold also includes a locking structure for locking the frame 7 to restrict the up and down movement of the frame 7. The locking structure includes a rotating rod 10 rotatably connected to the inner top wall of the frame 7, a transmission gear 11 fixedly connected to the outside of the rotating rod 10, a driven gear 12 meshing with the transmission gear 11, a threaded rod 13 fixedly connected to the inside of the driven gear 12, a threaded block 14 threadedly connected to the outside of the threaded rod 13, a locking rod 15 fixedly connected to the threaded block 14, and a support plate 16 fixedly connected between the inner top wall and the inner bottom wall of the base 1. The inner side of the support plate 16 has a locking hole adapted to the locking rod 15.
[0018] Specifically, four elastic telescopic components 6 are respectively arranged at the four corners of the bottom of the frame 7, and four top rods 8 are respectively arranged at the four corners of the top of the frame 7.
[0019] It should be noted that the four elastic expansion joints 6 are respectively arranged at the four corners of the bottom of the frame 7. This arrangement ensures that the frame 7 is subjected to uniform force under the action of the elastic expansion joints 6. In this way, the top template 9 can remain horizontal during the rising or falling process, avoiding tilting due to uneven force, which would affect the demolding effect and the forming quality of the welding plate.
[0020] Specifically, there are two driven gears 12, which are located on the left and right sides of the transmission gear 11. The two driven gears 12 mesh with the transmission gear 11 respectively. A threaded rod 13 is fixedly connected to the inner side of each driven gear 12. A threaded block 14 is threadedly connected to the end of each threaded rod 13 that is away from the driven gear 12. Locking rods 15 are fixedly connected to the opposite side walls of the threaded blocks 14 on both the left and right sides.
[0021] It should be noted that when the locking rod 15 is inserted into the locking hole, it can restrict the up and down movement of the frame 7 and ensure the stability of the mold during the forming process of the welding plate; when demolding is required, the locking rod 15 is removed from the locking hole, and the frame 7 can rise under the action of the elastic telescopic member 6 to achieve demolding.
[0022] Specifically, there are two support plates 16, and the two support plates 16 are located on the left and right sides of the frame 7 respectively. Each support plate 16 has a locking hole on its inner side that is compatible with the locking rod 15.
[0023] Specifically, a torsion cap is fixedly connected to the bottom end of the rotating rod 10, and both the transmission gear 11 and the driven gear 12 are bevel gears.
[0024] Specifically, the end of each threaded rod 13 that is away from the driven gear 12 is rotatably connected to the inner side wall of the frame 7.
[0025] The working principle of the above embodiments is as follows: After the welding plate is formed, the twist cap at the bottom of the rotating rod 10 is rotated, causing the rotating rod 10 to rotate. The rotating rod 10 drives the transmission gear 11 to rotate. The transmission gear 11 meshes with the driven gear 12, causing the driven gear 12 to drive the threaded rod 13 to rotate. The rotation of the threaded rod 13 causes the threaded block 14 to move away from the support plate 16, thereby causing the locking rod 15 to exit from the locking hole inside the support plate 16, releasing the lock on the frame 7. After the locking rod 15 exits the locking hole, due to the elasticity of the elastic telescopic member 6, under the action of the elastic force, the elastic telescopic member 6 extends upward, pushing the frame 7 to move upward. The frame 7 drives the four top rods 8 at the top to move upward. The four top rods 8 together push the top template 9 to move upward. The top template 9 pushes the formed welding plate out of the lower mold 3, realizing the demolding operation.
[0026] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
