[0030] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0031] like Figure 1-10 As shown, an automotive parts stamping machine includes a base frame 1 on which a lower die base 2 and a stamping plate 31 that moves and moves toward the lower die base 2 are provided. Both the base frame 1 and the lower die base 2 are provided with a blanking groove 9. A movable seat 5 is slidably provided in the base frame 1. A rubber plate 4 is fixedly connected to the movable seat 5. When the movable seat 5 is driven to slide, the rubber plate 4 moves horizontally and extends into the blanking groove 9. The rubber plate 4 is deformed in the blanking groove 9 and arches back toward the lower die base 2.

[0032] Specifically, such as Figure 1 As shown, the base frame 1 is also equipped with a first drive cylinder 32 for driving the stamping plate 31 to move towards the lower die base 2 for stamping operations. The base frame 1 is provided with a movable groove 11 and a sliding groove 12. The movable seat 5 is slidably disposed in the sliding groove 12 so that the rubber plate 4 is located in the movable groove 11 and moves. The rubber plate 4 is fixedly connected to the fixing part 55 of the movable seat 5. A second drive cylinder 6 for driving the movable seat 5 to slide is also provided in the sliding groove 12. The output end of the second drive cylinder 6 abuts against the mounting hole 54 of the movable seat 5. A collection box 8 is also provided below the material drop trough 9 of the base frame 1.

[0033] When the stamping plate 31 moves closer to the lower die base 2 and completes the stamping operation, the cutting edge of the stamping plate 31 enters the blanking groove 9 of the lower die base 2. At this time, the second drive cylinder 6 can be used to drive the movable seat 5 to slide. The movable seat 5 drives the rubber plate 4 to move horizontally so that the end of the rubber plate 4 moves horizontally and extends into the blanking groove 9. The rubber plate 4 moves to scrape the cutting edge of the stamping plate 31 to remove the scrap material on the cutting edge of the stamping plate 31, thereby improving the stability of subsequent stamping operations. When the rubber plate 4 moves to the point where its end abuts against the side wall of the blanking groove 9, the rubber plate 4 continues to move into the blanking groove 9 so that the rubber plate 4 arches against the side of the lower die base 2. The movable seat 5 drives the rubber plate 4 to deform and push the scrap material stuck in the blanking groove 9 to move down, avoiding the problem of scrap material blockage caused by the scrap material plate surface getting stuck in the blanking groove 9, and improving the stability of the stamping operation.

[0034] The first drive cylinder 32 and the second drive cylinder 6 are common technical knowledge to those skilled in the art and will not be described in detail here.

[0035] In the above technical solution, the movable seat 5 drives the rubber plate 4 to deform and push the stuck waste material in the discharge chute 9 to move and fall, thereby avoiding the problem of material blockage caused by the waste material plate being stuck in the discharge chute 9 and improving the stability of the stamping operation.

[0036] As a further embodiment provided in this utility model, a chamfered portion 41 is provided on the first end of the rubber plate 4 on the side facing away from the mold base 2.

[0037] Specifically, such as Figure 8 As shown, the end of the rubber plate 4 facing the blanking groove 9 is the first end, and a chamfered part 41 is provided on the side facing away from the mold base 2. The presence of the chamfered part 41 can further facilitate the rubber plate 4 to scrape off the debris on the cutting edge of the stamping plate 31, and can also facilitate the deformation and arching of the rubber plate 4 when the end of the rubber plate 4 abuts against the side wall of the blanking groove 9, ensuring the stability of the rubber plate 4 in pushing the waste material to fall.

[0038] As a further embodiment provided in this utility model, the first side surface of the rubber sheet 4 is provided with a linear array of lower grooves 42.

[0039] Specifically, such as Figure 8 As shown, the side of the rubber plate 4 facing the lower mold base 2 is the first side, on which several lower grooves 42 are formed. When the rubber plate 4 moves horizontally to scrape the cutting edge of the stamping plate 31, the lower grooves 42 can further apply scraping pressure to the cutting edge of the stamping plate 31, thereby achieving better cleaning of the cutting edge of the stamping plate 31. Secondly, the grooves on the first side of the rubber plate 4 facilitate the arching deformation of the rubber plate 4 facing away from the first side.

[0040] As a further embodiment provided in this utility model, a lifting member 7 is vertically slidably disposed on the lower mold base 2, and the movable seat 5 is driven to move to push the lifting member 7 to slide out of the lower mold base 2.

[0041] Specifically, such as Figure 9 As shown, the pusher 7 is vertically slidably arranged on the lower die base 2, and the pusher 7 is located inside the lower die base 2 by default. When the stamping plate 31 moves closer to the lower die base 2 to complete the stamping operation, and when the stamping plate 31 moves away from the lower die base 2, it can drive the movable seat 5 to move so that the movable seat 5 pushes the pusher 7 vertically, thereby causing the pusher 7 to slide vertically out of the outer side of the lower die base 2 to push out the workpiece on the lower die base 2, thereby improving the output efficiency of the stamping operation.

[0042] As a further embodiment of this utility model, the movable seat 5 is provided with an extension 51, the extension 51 is provided with a push slope 52, the push member 7 is provided with a guide slope 71, and the movable seat 5 is driven to move so that the push slope 52 abuts against the guide slope 71.

[0043] Specifically, such as Figure 6 As shown, there is a push slope 52 on the extension 51 of the movable seat 5, and a guide slope 71 on the lifting member 7, and as... Figure 9 As shown, the push slope 52 and the guide slope 71 are aligned. When the movable seat 5 is driven to slide and push the rubber plate 4 horizontally, the movable seat 5 also causes the push slope 52 to move closer to the guide slope 71, and the push slope 52 moves to contact the guide slope 71 and moves along the guide slope 71, thereby driving the lifting member 7 to slide vertically upward to extend out of the lower mold base 2. The push slope 52 and the guide slope 71 are used to drive the lifting member 7 by the movable seat 5, improving the stability of the lifting member 7 in ejecting material.

[0044] As a further embodiment provided in this utility model, a protrusion 72 is provided on the first end of the pusher 7, and an abutment groove 53 is provided on the extension 51.

[0045] Specifically, such as Figure 9As shown, the end of the pusher 7 closest to the rubber plate 4 is the first end, which has a protrusion 72. When the rubber plate 4 is driven to move horizontally, the protrusion 72 sequentially enters and passes through the lower groove 42 on the rubber plate 4, causing the rubber plate 4 to vibrate. This allows the rubber plate 4 to better scrape and clean the cutting edge of the stamping plate 31. When the movable seat 5 moves to contact the protrusion 72 of the pusher 7, the pusher 7 vibrates vertically to better eject the product stuck to the lower die base 2, improving the stability of the ejection process.

[0046] As a further embodiment provided in this utility model, the pusher 7 is symmetrically provided with sliding parts 73, the lower mold base 2 is provided with mounting groove 21, and a vertical sliding groove 22 is provided in the mounting groove 21. The pusher 7 is located in the mounting groove 21 so that the sliding parts 73 are located in the vertical sliding groove 22.

[0047] Specifically, such as Figure 10 As shown, the sliding part 73 of the pusher 7 is slidably disposed in the vertical groove 22 of the lower mold base 2 to further improve the vertical sliding stability of the pusher 7.

[0048] As a further embodiment of this utility model, it also includes an elastic member 74 disposed in the vertical slide groove 22 to drive the pusher 7 to slide and retract into the lower mold base 2.

[0049] Specifically, the elastic element 74 provided in the vertical slide groove 22 pushes the lifting element 7 to slide back to the lower die base 2, thereby preventing the lifting element 7 from affecting the product shape of the stamping operation and ensuring the product accuracy of the stamping operation.

[0050] The elastic element 74 can be replaced by any elastic object known to those skilled in the art, such as a spring, airbag, or elastic plate.

[0051] As a further embodiment provided in this utility model, the movable seat 5 is made of Teflon.

[0052] Specifically, the movable seat 5 is made of Teflon to improve its wear resistance while reducing its sliding resistance, thus facilitating the sliding of the movable seat 5.

[0053] As a further embodiment provided in this utility model, the rubber sheet 4 is a wear-resistant rubber component.

[0054] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
