Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die with an auxiliary loading and unloading structure. Background Technique

[0002] A stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products), which is called a cold stamping die (commonly known as a cold punching die). Stamping is a pressure processing method in which, at room temperature, a die installed on a press applies pressure to a material to cause separation or plastic deformation, thereby obtaining the required parts. The patent with publication number CN220261260U discloses a stamping die, including a workbench. Above the workbench, a driving mechanism is installed. At the top of the workbench, a forming mechanism is provided. Above the workbench, a stamping mechanism is installed. The stamping mechanism includes a plurality of telescopic rods. Springs are fixedly connected to the telescopic rods. At the bottom of the telescopic rods, a stamping installation box is fixedly installed. A punch fixing seat is slidably installed in the stamping installation box. At the bottom of the punch fixing seat, a plurality of punches for processing remote control buttons are fixedly connected. At the bottom of the stamping installation box, a cutting knife for cutting out the remote control panel is fixedly connected. At the bottom edge of the stamping installation box, a washer is fixedly connected. The beneficial effects are as follows: The forming mechanism and the stamping mechanism are provided. Through the cooperation of the punches and the through holes, the scraps and debris generated during the stamping work are pushed into the collection box, eliminating the cleaning work, realizing continuous automatic processing work, and saving labor. Although this product can push the scraps and debris generated during the stamping work into the collection box and eliminate the cleaning work, this product does not have a structure for assisting loading and unloading. When loading, workers need to manually place the raw materials on the die for stamping processing, which poses a certain danger during loading. Once a danger occurs, it will cause irreversible harm to the workers. When demolding, workers need to use demolding tools to demold the processed metal silicon die, and the process is relatively slow, thus increasing the workload of the workers and reducing the production efficiency, and improvement is needed.

[0003] The purpose of the utility model is to solve the technical problems raised in the above background technique.

[0004] The utility model adopts the following technical scheme: a stamping die with an auxiliary structure for loading and unloading, including a chassis, a support column, and a top plate. A hydraulic cylinder A is fixedly installed on the surface of the top plate. The output end of the hydraulic cylinder A is fixedly connected to an upper die. A lower die is fixedly installed on the surface of the chassis. A material guide box is fixedly installed on the surface of the chassis. A hydraulic cylinder B is fixedly installed on the side of the material guide box. A push plate is slidably connected inside the material guide box. A slider is fixedly installed on the side of the push plate. A backing plate is fixedly installed on the side of the push plate. A top block is slidably connected inside the chassis.

[0005] Preferably, the output end of the hydraulic cylinder B is fixedly connected to one side of the push plate, and the slider is slidably connected with the material guide box. Here, by driving the push plate to expand and contract through the hydraulic cylinder B, the raw materials inside the material guide box can be pushed into the lower die, so that it is not necessary for workers to manually place the raw materials on the die for stamping processing. The slider ensures that the push plate can slide stably during the pushing process without jamming.

[0006] Preferably, the top block is slidably connected with the lower die, and the threaded rod is threadedly connected with the cross plate. Here, the cross plate drives the top block to move up and down synchronously through the threaded rod, so that the top block ejects the processed die inside the lower die, avoiding the need for workers to use demoulding tools to demould the processed die.

[0007] Preferably, the threaded rod is rotatably connected with the bearing, and the cross plate is slidably connected with the sliding rod. Here, the bearing makes the threaded rod rotate more smoothly, and the sliding rod ensures that the cross plate can move up and down stably.

A limiting hole is formed on the surface of the lower die. A limiting sleeve is fixedly installed inside the upper die. A limiting rod is slidably connected inside the limiting sleeve. A spring is fixedly connected inside the limiting sleeve. Here, it plays a role in guiding the upper die, avoiding the deviation of the upper die during the movement process, ensuring the stability and accuracy of the closing and opening of the upper die, and at the same time reducing the friction and wear during the opening and closing process of the upper die, thereby improving the service life and operation efficiency of the die.

[0009] Preferably, one end of the guiding rod is fixedly connected to the side of the top plate, and the guiding rod is slidably connected with the fixing plate. Here, the guiding rod can guide and stabilize the movement of the lower die, reduce the deviation of the upper die during the movement process, and ensure the accurate alignment of the upper die.

[0010] Preferably, the limiting rod is slidably connected to the limiting hole, and one end of the spring is fixedly connected to one end of the limiting rod. Here, the elastic force provided by the spring can buffer the movement of the mold and reduce the frictional force of direct contact.

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

The hydraulic cylinder B drives the push plate to expand and contract, and can push the raw materials inside the feeding box into the lower mold, so that it is not necessary for the staff to manually place the raw materials on the mold for stamping. The threaded rod makes the cross plate drive the push plate to move up and down synchronously, so that the push plate ejects the processed mold inside the lower mold, avoiding the need for the staff to use a demoulding tool to demould the processed mold, thereby improving the production efficiency.

[0025] Please refer to Figures 1-3, the output end of the hydraulic cylinder B8 is fixedly connected to one side of the push plate 9. The slider 10 is slidably connected to the material guide box 7. By driving the push plate 9 to expand and contract through the hydraulic cylinder B8, the raw materials inside the material guide box 7 can be pushed into the lower die 6, so that there is no need for workers to manually place the raw materials on the die for stamping. The slider 10 ensures that the push plate 9 can slide stably during the pushing process without jamming. The ejector block 12 is slidably connected to the lower die 6. The threaded rod 17 is threadedly connected to the cross plate 14. By rotating the threaded rod 17, the cross plate 14 drives the ejector block 12 to move up and down synchronously, so that the ejector block 12 ejects the processed die inside the lower die 6, avoiding the need for workers to use demoulding tools to demould the processed die. The threaded rod 17 is rotatably connected to the bearing 16. The cross plate 14 is slidably connected to the slide rod 18. The bearing 16 makes the threaded rod 17 rotate more smoothly, and the slide rod 18 ensures that the cross plate 14 can move up and down stably.

[0026] Embodiment 2

[0027] Please refer to Figures 3-5 , a fixed plate 19 is fixedly installed on the side surface of the upper die 5. A guide rod 20 is fixedly installed on the surface of the chassis 1. A limit hole 21 is formed on the surface of the lower die 6. A limit sleeve 22 is fixedly installed inside the upper die 5. A limit rod 23 is slidably connected inside the limit sleeve 22. A spring 24 is fixedly connected inside the limit sleeve 22, which realizes the function of guiding the upper die 5, avoiding the deviation of the upper die 5 during the movement process, ensuring the stability and accuracy of the closing and opening of the upper die 5, and at the same time reducing the friction and wear during the opening and closing process of the upper die 5, thereby improving the service life and operation efficiency of the die. One end of the guide rod 20 is fixedly connected to the side surface of the top plate 3. The guide rod 20 is slidably connected to the fixed plate 19. The guide rod 20 can guide and stabilize the movement of the lower die 6, reducing the deviation of the upper die 5 during the movement process and ensuring the accurate alignment of the upper die 5. The limit rod 23 is slidably connected to the limit hole 21. One end of the spring 24 is fixedly connected to one end of the limit rod 23. The elastic force provided by the spring 24 can buffer the movement of the die and reduce the direct contact friction.

[0028] Working principle: When in use, first place the raw materials into the feeding box 7. Then, by starting the hydraulic cylinder B8, the output end of the hydraulic cylinder will drive the push plate 9 to expand and contract, thereby pushing the raw materials inside the feeding box 7 into the lower mold 6. At the same time, the sliding block will slide inside the feeding box 7 to ensure that the push plate 9 can slide stably during the pushing process without jamming. Thus, there is no need for workers to manually place the raw materials on the mold for stamping processing, reducing the risk of accidental injuries caused by improper operation. Then, start the hydraulic cylinder A4 to drive the upper mold 5 to move downward. At this time, the upper mold 5 presses the lower mold 6 to make the workpiece compression-molded. When the lower mold 6 moves downward, the fixed block will slide on the surface of the guide rod 20. The guide rod 20 can guide and stabilize the movement of the lower mold 6, reducing the offset of the upper mold 5 during the movement process and ensuring the accurate alignment of the upper mold 5. When moving to a certain position, the limit rod 23 will slide into the lower mold 6. At this time, the limit rod 23 will contract and the spring 24 will be compressed. The elastic force provided by the spring 24 can buffer the movement of the mold, reducing the friction and wear of the upper mold 5 during the opening and closing process. When it is necessary to demold the stamped mold, first start the motor 15. The output end of the motor 15 will drive the threaded rod 17 to rotate. Since the threaded rod 17 is threadedly connected to the cross plate 14, the cross plate 14 will move up and down, causing the connecting rod 13 and the top block 12 to move synchronously, so that the top block 12 ejects the processed mold inside the lower mold 6. This avoids the need for workers to use demolding tools to demold the processed mold, thereby improving production efficiency and reducing the labor intensity of workers.

[0029] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
