Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a deep drawing blanking mold for automotive reinforcement parts. Background Technology

[0002] Automotive reinforcement parts are generally formed by deep drawing blanking dies, which mainly include an upper die and a lower die. The upper die is connected to a stamping cylinder. The stamping cylinder presses the upper die down to close with the lower die. The material on the lower die is stamped into the lower die to form the workpiece with the required contour, and the remaining waste material is left on the lower die base.

[0003] However, existing deep drawing blanking dies are not convenient to automatically unload the workpiece from the die after stamping, resulting in low unloading efficiency. Furthermore, when producing different automotive reinforcement parts, the fixed stroke of the stamping cylinder may lead to incomplete die closing due to insufficient stroke, thus affecting the stamping strength of the automotive reinforcement parts. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a deep drawing blanking die for automotive reinforcement parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A deep drawing blanking die for automotive reinforcement parts includes a lower die structure and an upper die structure. The lower die structure includes a support base, a lower die base fixedly connected to the top outer wall of the support base, three dies disposed on the top of the lower die base, and three elastic telescopic rods.

[0007] Each of the three elastic telescopic rods includes a hollow rod fixedly connected to the inner wall of the bottom of the support base, a discharge rod slidably connected to the hollow rod, and a spring fixedly connected to the inner wall of the bottom of the hollow rod;

[0008] The upper mold structure includes a support frame fixedly connected to the outer wall of the back of the support base, a range extender, a precision guide, a stamping cylinder, an upper mold base fixedly connected to the piston rod end of the stamping cylinder, and three punches fixedly connected to the bottom outer wall of the upper mold base.

[0009] The range extender assembly includes a servo self-locking motor fixedly mounted on the outer wall of the back of the support frame by bolts, an adjusting screw fixedly connected to the output shaft of the servo self-locking motor by a coupling, and an adjusting plate threadedly connected to the adjusting screw. The stamping cylinder is fixedly mounted on the outer wall of the front of the adjusting plate by bolts.

[0010] Preferably, the three concave dies, the three elastic telescopic rods, and the three convex dies are all arranged at equal distances.

[0011] Preferably, the bottom inner walls of the three dies are provided with through holes, the outer walls of the three unloading rods are slidably connected to the inner walls of the three through holes, and the top outer walls of the three springs are respectively welded to the bottom outer walls of the three unloading rods.

[0012] Preferably, the support frame has sliding grooves on both sides, and the adjusting plate is slidably connected between the two sliding grooves.

[0013] Preferably, two bearing seats are symmetrically fixed on the outer wall of the back of the support frame, and the adjusting screw is rotatably mounted on the two bearing seats.

[0014] Preferably, the precision guiding assembly includes four guide rods welded sequentially to the outer walls of the four corners of the top of the lower mold base, four linear bearings fixedly embedded in the four corners of the upper mold base, and four anti-detachment discs welded sequentially to the outer walls of the top of the four guide rods, with the four linear bearings being movably connected to the four guide rods respectively.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. In the process of mold closing, the three ejector rods are squeezed and the three springs are continuously compressed. When the mold closing action is completed, under the elastic reset effect of the three springs, the three ejector rods will automatically push the three automotive reinforcement parts formed in the three cavities upward. This facilitates the automatic unloading of the automotive reinforcement parts formed in the three cavities, effectively improving the unloading efficiency.

[0017] 2. When the stroke of the stamping cylinder is insufficient, the stroke of the stamping cylinder can be increased by the stroke extender, which solves the problem that the mold closing may be incomplete due to insufficient stroke. This makes it easier to adapt to the stamping of different automotive reinforcing parts and helps to ensure the stamping strength of different automotive reinforcing parts.

[0025] Specifically, the lower mold structure includes a support base 1, a lower mold base 2 fixedly connected to the top outer wall of the support base 1, three concave molds 3 located on the top of the lower mold base 2, and three elastic telescopic rods.

[0026] Furthermore, each of the three elastic telescopic rods includes a hollow rod 4 fixedly connected to the inner wall of the bottom of the support base 1, a discharge rod 5 slidably connected to the hollow rod 4, and a spring 6 fixedly connected to the inner wall of the bottom of the hollow rod 4;

[0027] Specifically, the upper mold structure includes a support frame 7 fixedly connected to the outer wall of the back of the support base 1, a range extender, a precision guide, a stamping cylinder 8, an upper mold base 9 fixedly connected to the piston rod end of the stamping cylinder 8, and three punches 10 fixedly connected to the bottom outer wall of the upper mold base 9.

[0028] Furthermore, the three concave dies 3, the three elastic telescopic rods and the three convex dies 10 are all distributed at equal distances. The bottom inner walls of the three concave dies 3 are all provided with through holes. The outer walls of the three unloading rods 5 are slidably connected to the inner walls of the three through holes respectively. The top outer walls of the three springs 6 are respectively welded to the bottom outer walls of the three unloading rods 5.

[0029] In this embodiment, during the mold closing process, the three ejector rods 5 are squeezed and the three springs 6 are continuously compressed. When the mold closing action is completed, under the elastic reset effect of the three springs 6, the three ejector rods 5 will automatically push the automotive reinforcement parts formed in the three concave molds 3 upward. This facilitates the automatic unloading of the formed automotive reinforcement parts in the three concave molds 3, effectively improving the unloading efficiency.

[0030] Example 2, refer to Figure 1 and Figure 4This embodiment is an optimization based on embodiment 1. Specifically, the range extender includes a servo self-locking motor 11 that is fixedly mounted on the outer wall of the back of the support frame 7 by bolts, an adjusting screw 12 that is fixedly connected to the output shaft of the servo self-locking motor 11 by a coupling, and an adjusting plate 13 that is threadedly connected to the adjusting screw 12. The stamping cylinder 8 is fixedly mounted on the outer wall of the front of the adjusting plate 13 by bolts.

[0031] Furthermore, the support frame 7 has sliding grooves on both sides, and the adjusting plate 13 is slidably connected between the two sliding grooves. The two sliding grooves ensure the stability of the linear movement of the adjusting plate 13, which is threadedly connected to the adjusting screw 12. Two bearing seats 14 are symmetrically fixed on the outer wall of the back of the support frame 7. The adjusting screw 12 is rotatably mounted on the two bearing seats 14. The two bearing seats 14 ensure the stability of the rotation of the adjusting screw 12.

[0032] Furthermore, the precision guiding component includes four guide rods 15 that are sequentially welded to the outer walls of the four corners of the top of the lower mold base 2, four linear bearings that are sequentially fixed and embedded at the four corners of the upper mold base 9, and four anti-detachment discs 16 that are sequentially welded to the outer walls of the top of the four guide rods 15. The four linear bearings are movably connected to the four guide rods 15 respectively. Through the guiding effect of the precision guiding component, the accuracy of the mold closing action can be guaranteed, and misalignment can be avoided, which would affect the forming quality of the workpiece.

[0033] In this embodiment, when the stroke of the stamping cylinder 8 is insufficient, the stroke of the stamping cylinder 8 can be increased by the stroke extender, which solves the problem that the mold closing may be incomplete due to insufficient stroke. This makes it easier to adapt to the stamping of different automotive reinforcing parts and helps to ensure the stamping strength of different automotive reinforcing parts.

[0034] Working principle: First, the three punches 10 on the upper die holder 9 are moved downward by the stamping cylinder 8. During this process, the precision guide component ensures the accuracy of the movement of the three punches 10. Then, the three punches 10 will press the material on the lower die holder 2 into the three dies 3 to form the required automotive reinforcement. At this point, the entire mold closing action can be completed. During the mold closing process, the three stripper rods 5 will be squeezed and the three springs 6 will be continuously compressed.

[0035] Secondly, after the mold closing action is completed, the three punches 10 on the upper mold base 9 are moved upward by the stamping cylinder 8. At this time, under the elastic reset effect of the three springs 6, the three unloading rods 5 will automatically push the automotive reinforcement parts formed in the three cavities 3 upward. This makes it easier to automatically unload the automotive reinforcement parts formed in the three cavities 3, which effectively improves the unloading efficiency.

[0036] Finally, when the stroke of the stamping cylinder 8 is insufficient, the servo self-locking motor 11 drives the adjusting screw 12 to rotate. Then, under the limit of the two slides, the adjusting plate 13, which is threadedly connected to the adjusting screw 12, will drive the stamping cylinder 8 to move downward to increase the stroke of the stamping cylinder 8. This solves the problem that the mold may not close completely due to insufficient stroke, thus making it easier to adapt to the stamping of different automotive reinforcing parts and helping to ensure the stamping strength of different automotive reinforcing parts.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
