Compared with manual operation, stamping dies can realize fully automated continuous processing, effectively shortening the production cycle, improving production efficiency and production capacity.

[0003] Some stamping parts with special shapes, large sizes or complex structures may not be easily ejected completely by the ejector device. This may require manual or other tools to remove the stamping parts. Manually removing the parts will increase the additional operation time, resulting in an extended production cycle. At the same time, manually removing stamping parts requires additional labor input, increasing the labor cost. The inability to automatically strip the material will interrupt the continuity of production, causing the production line to stop frequently and affecting the overall production progress.

[0004] Therefore, it is necessary to invent a stripping device for a stamping die to solve the above problems. Summary of the Utility Model

[0020] The present utility model will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0021] The present utility model provides a blanking device for a stamping die as shown in Figures 1-4 which includes a lower fixing plate 1, an upper fixing plate 3, a stamping assembly 5, a punch 22 and a die 23. The punch 22 is detachably installed inside the lower die 14, and the punch 22 is detachably installed inside the upper die 10. The lower die 14 is installed at the top of the lower fixing plate 1, and the upper die 10 is installed at the bottom of the stamping assembly 5. A lifting module 9 for synchronously driving the stamping part to lift is arranged inside the upper die 10, and a push rod 12 for ejecting the part is slidably arranged inside the upper die 10. A receiving slideway 6 for reciprocally sliding and receiving the stamping part is arranged on one side of the lower fixing plate 1. Setting the die 23 on the upper die 10 is convenient for the formed part to stay inside the upper die 10, convenient for rising with the rise of the stamping assembly 5, and convenient for achieving the purpose of automatic blanking and reducing the difficulty of automatic blanking.

[0022] The lower fixing plate 1 and the upper fixing plate 3 are fixedly connected by a plurality of support columns 2. A baffle 4 for pushing the push rod 12 to eject is connected to the bottom end of the upper fixing plate 3. A plurality of guide pipes 11 for the longitudinal sliding of the push rod 12 are detachably installed at the bottom end of the baffle 4. A plurality of receiving grooves 13 for receiving the guide pipes 11 are opened at the top end of the upper die 10. When the punch 22 is in contact with the die 23, the end faces of the plurality of push rods 12 are in contact with the inner surface of the die 23. Through the setting of the push rod 12, when the upper die 10 moves to a certain position, the push rod 12 is squeezed by the baffle 4, so that the push rod 12 ejects the stamping part inside the upper die 10, which is convenient for the lower receiving slideway 6 to receive it.

[0023] The lifting module 9 is located on both sides of the upper die 10. A plurality of ejector blocks 17 for lifting stamping parts that can slide back and forth are installed inside the lifting module 9. A plurality of ejector springs 16 are arranged on the end faces of the ejector blocks 17. The ejector blocks 17 penetrate through and extend to the inner surface of the upper die 10. The arrangement of the ejector springs 16 facilitates the telescopic movement of the plurality of ejector blocks 17. When the upper die 10 is fitted with the lower die 14, the ejector blocks 17 are retracted on the outside of the lower die 14 to avoid interference with the stamping parts during the stamping process.

[0024] The lower die 14 is located on one side of the lifting module 9 and is provided with a plurality of lower lifting grooves 19 and upper lifting grooves 20 for sliding of the ejection blocks 17. The lower lifting grooves 19 are provided with inclined surfaces and rounded corners for facilitating the sliding of the ejection blocks 17 along the contour. When the upper die 10 is lifted to a certain height, the plurality of ejection blocks 17 lift the stamped parts. When the lifting continues, the ejection blocks 17 located in the lower lifting grooves 19 are separated by the action of the inclined surfaces and rounded corners, and the ejection blocks 17 located in the upper lifting grooves 20 are limited by the action of the guide rods 8 and the ejection springs 16 to follow the lifting, thereby collecting the stamped parts.

[0025] The top pipe of the lifting module 9 is penetrated by a slide groove 15, and the top of the lower fixed plate 1 is installed with a guide rod 8 for controlling the sliding direction of the ejection block 17 corresponding to the upper lifting groove 20. The top of the ejection block 17 corresponding to the upper lifting groove 20 is provided with a slide groove 28, and the guide rod 8 is penetrated by the slide groove 15 and the slide groove 2 18 at the same time. The curved setting of the guide rod 8 can make the ejection block 17 shrink when reaching the top and extend during the rising process, thereby avoiding the premature falling off of the stamped parts.

[0026] A positioning block 21 for fixing the plate is provided at the top of the lower mold 14, and a mounting plate 7 is provided on one side of the lower mold 14. The mounting plate 7 is provided with a plurality of telescopic components 24 for driving the receiving slide 6 to slide inward. The receiving slide 6 is inclined, and a storage device is provided at the end of the receiving slide 6. During the falling process of the stamping component 5, the telescopic component 24 will drive the receiving slide 6 to reset, thereby realizing the process of automatic material removal and unloading.

[0027] In this utility model, after the stamping part is formed, the lifting module 9 moves the stamping part from the lower die 14 to the upper die 10. After the upper die 10 is lifted, the telescopic component 24 controls the receiving slide to slide below the upper die 10. Through the extrusion of the push rod 12 and the baffle 4, and the guide rod 8 drives the ejector block 17 to slide outwards, so that the stamping part falls on the inclined receiving slide, realizing the stripping of the stamping part in the stamping die. The automatic stripping technology can reduce manual intervention and the operation difficulty, thereby improving the overall production efficiency. Compared with the traditional manual stripping method, the automatic stripping can complete the stripping process faster, reduce the production time, reduce the dependence on human resources, and lower the labor cost. At the same time, since the automatic stripping system can work continuously and stably, it can reduce the production fluctuations and losses caused by human factors.

[0028] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
