[0027] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] This embodiment provides a continuous die for stamping a car door lock. Figures 1-4 As shown, the automobile door lock stamping continuous die includes a base 1, a back plate 2 fixedly arranged on the base 1, a top plate 3 fixedly arranged on the top of the back plate 2, a pressure-bearing structure 5 arranged at a position below the base 1 corresponding to the top plate 3 for placing the lock raw material, a stamping structure 4 fixedly arranged on the top plate 3 for stamping the lock raw material on the pressure-bearing structure 5, and a pushing structure 6 arranged on the back plate 2 for pushing the lock on the pressure-bearing structure 5 to unload the material; a receiving groove 21 is provided at a position of the back plate 2 corresponding to the pushing structure 6; the pushing structure 6 includes a push plate 61 arranged in the receiving groove 21, a second driving member 62 fixedly arranged on the side of the back plate 2 away from the pressure-bearing structure 5 for driving the push plate 61 to push the stamped lock, blowing holes 63 opened at the bottom of the push plate 61 and distributed in a rectangular array for blowing waste material on the pressure-bearing structure 5, and an inflation component 64 arranged on the back plate 2 and connected to the push plate 61 for inflating the blowing holes 63.

[0029] During use, the lock buckle raw material is placed on the pressure-bearing structure 5 to ensure that the raw material is in the correct position, and then the stamping structure 4 is started to stamp the lock buckle placed on the pressure-bearing structure 5 to obtain the formed lock buckle. Then, the second driving member 62 is started to drive the push plate 61 to move. As the push plate 61 moves, the lock buckle stamped and formed on the pressure-bearing structure 5 will be automatically pushed out by the push plate 61 without manual unloading. At the same time, due to the connection between the inflation component 64 and the push plate 61 and the back plate 2, when the second driving member 62 pushes the push plate 61 back into the accommodating groove 21, the inflation component 64 can be inflated into the blowing hole 63 at the bottom end of the second driving member 62, and the waste material on the pressure-bearing structure 5 is blown away through the blowing hole 63 to reduce the impact of the waste material on the next stamping operation, so as to reduce the impact of the waste material on the next stamping operation.

[0030] Specifically, the punching structure 4 includes a lifting plate 41 that moves longitudinally below the top plate 3, a punching head 42 fixedly provided at the bottom end of the lifting plate 41, a guide rod 44 fixedly provided on the top plate 3 and the base 1 and longitudinally passing through the lifting plate 41, and a first driving member 43 fixedly provided on the top plate 3 for driving the lifting plate 41 to move. The lifting plate 41 is slidably connected to the guide rod 44.

[0031] After placing the lock buckle raw material on the pressure-bearing structure 5 and ensuring that the raw material is in the correct position, the first driving member 43 can be started to drive the lifting plate 41 to descend. Since the bottom end of the lifting plate 41 is connected to the punching head 42, and the lifting plate 41 is slidably connected to the guide rod 44, when the first driving member 43 drives the lifting plate 41 to descend, the lifting plate 41 can stably drive the punching head 42 to descend. As the punching head 42 descends, the punching head 42 gradually approaches and contacts the lock buckle raw material placed on the pressure-bearing structure 5. Then, under the pressure of the punching head 42, the lock buckle raw material undergoes plastic deformation to form the required stamping shape, thereby obtaining the formed lock buckle. Finally, the first driving member 43 drives the lifting plate 41 and the punching head 42 to rise to the initial position.

[0032] Among them, in order to meet different stamping and blanking requirements, the first driving member 43 and the second driving member 62 are both cylinders; the first driving member 43 and the second driving member 62 are both cylinders. Since the driving force of the cylinder is large and stable, it can meet the speed and force requirements during stamping and blanking.

[0033] Furthermore, the pressure-bearing structure 5 includes a support seat 51 symmetrically fixedly arranged on the base 1 at a position corresponding to the bottom of the lifting plate 41, a pressure plate 52 that moves longitudinally between the two support seats 51 and is located below the punching head 42, a fixed cylinder 53 fixedly arranged on the base 1, a connecting rod 54 that longitudinally penetrates the fixed cylinder 53 and the base 1 and is fixedly connected to the bottom end of the pressure plate 52, and a spring 55 that is sleeved on the connecting rod 54 and has its two ends fixedly connected to the fixed cylinder 53 and the connecting rod 54 respectively, and the connecting rod 54 is slidably connected in the fixed cylinder 53; the cross-section of the two support seats 51 and the pressure plate 52 is a U-shaped structure.

[0034] It should be added that the initial height of the pressure plate 52 before being pressed down by the punch head 42 is consistent with the height of the push plate 61, so that the second driving member 62 drives the push plate 61 to automatically push the formed lock on the pressure plate 52 to be unloaded.

[0035] Since the cross-section of the two support seats 51 and the pressure plate 52 is a U-shaped structure, the lock material can be placed on the two support seats 51 and the pressure plate 52 by the support of the two support seats 51 and the pressure plate 52 during the stamping process. When the first driving member 43 is started to drive the punching head 42 to punch the placed lock material, the punching head 42 will descend and contact the lock material placed on the pressure plate 52. However, under the pressure of the punching head 42, the lock material begins to plastically deform. At the same time, the pressure plate 52 is pressurized and moves downward. , driving the connecting rod 54 to slide in the fixed cylinder 53. During this process, the spring 55 can be compressed to play a buffering role, which can absorb part of the impact force and protect the equipment and the lock material from damage. When the punch head 42 drops to the preset punching stroke and completes the punching to obtain the formed lock, the first driving member 43 drives the punch head 42 to rise to the initial position. Under the elastic force of the spring 55, the pressure plate 52 begins to move upward and drives the connecting rod 54 to slide and reset in the fixed cylinder 53, preparing for the next punching operation.

[0036] Furthermore, the inflation assembly 64 includes an air cylinder 641 fixedly arranged on the side of the back plate 2 away from the accommodating groove 21, a piston 642 slidably connected in the air cylinder 641, a push rod 643 that transversely passes through the end of the air cylinder 641 away from the back plate 2 and is fixedly connected to the piston 642 and the push plate 61 at both ends, an air outlet pipe 644 fixedly arranged on the end of the air cylinder 641 away from the push rod 643 and is connected to the air cylinder 641 and the blowing hole 63 at both ends, and an air inlet pipe 645 fixedly arranged on one side of the air cylinder 641, and the air outlet pipe 644 is a hose.

[0037] It is understandable that one-way valves are provided in both the air outlet pipe 644 and the air inlet pipe 645 to prevent the gas from flowing back during air outlet or air inlet.

[0038] When the pressure plate 52 drives the formed lock to reset, the second driving member 62 is started to drive the push plate 61 to push the lock on the pressure plate 52 to unload. Since the push plate 61 is fixedly connected to one end of the push rod 643, when the push plate 61 moves close to the pressure plate 52, it will synchronously pull the push rod 643. At this time, the push rod 643 will synchronously pull the piston 642 to move inside the cylinder 641 close to the end of the push rod 643. As the piston 642 moves, external air enters the cylinder 641 from the air inlet pipe 645 and is stored. When the push plate 61 moves and pushes the formed lock, After the formed lock is unloaded, the second driving member 62 pushes the push plate 61 back to the accommodating groove 21. The push plate 61 will simultaneously push the push rod 643 to move. The push rod 643 will simultaneously push the piston 642 to move in the air cylinder 641 toward the end away from the push rod 643 and compress the gas in the air cylinder 641. Then, the compressed gas will be transported to the blowing hole 63 through the air outlet pipe 644, and finally blow air to the surface of the support seat 51 and the pressure plate 52 through the blowing hole 63 to reduce the residual waste and improve the accuracy of the next stamping.

[0039] In addition, in order to facilitate the movement of the air outlet pipe 644 with the movement of the push plate 61, the height of the accommodating groove 21 is greater than the height of the push plate 61; the height of the accommodating groove 21 is greater than the height of the push plate 61, which provides sufficient space for the movement of the air outlet pipe 644, avoiding bending or damage of the hose due to insufficient space.

[0040] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
