[0002] Stamping dies are specialized tools used in stamping processes. They are used to process metal or non-metal materials through punching, bending, stretching, and forming to manufacture the required parts or products. Stamping dies are widely used in the automotive, electronics, home appliance, and aerospace industries.

[0003] Currently, with traditional stamping dies, after the workpiece is stamped, the formed workpiece will stick to the forming groove of the die, making it difficult to remove the workpiece and affecting the actual stamping efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides an environmentally friendly and wear-resistant stamping die, which solves the problem that after the workpiece is stamped by the traditional stamping die, the formed workpiece will stick to the forming groove of the die, making it difficult to remove the workpiece and affecting the actual stamping efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly and wear-resistant stamping die, including a lower die base, a limiting plate connected above the lower die base, a forming plate connected to the lower die base via the limiting plate, slide rails connected to both sides of the limiting plate, a slide groove formed inside the lower die base, a motor fixedly installed on one side of the lower die base, a threaded rod connected to the output shaft of the motor, two movable plates installed on the threaded rod, and threaded sleeves connected to the movable plates;

[0006] The movable plate has sliding holes on both sides of the threaded sleeve. Push plates are connected to both sides of the movable plate. Guide grooves are provided on the push plates. Movable rods are slidably connected in the guide grooves. Vertical plates are connected to the movable rods. Ejector plates are connected to the vertical plates. Guide pillars are connected to the forming plate. Upper molds are slidably installed on the guide pillars. Side plates are connected to both sides of the upper molds.

[0007] As a further embodiment of this utility model: buffer springs are sleeved at both ends of the slide rail, one end of the buffer spring is connected to the limiting plate, and the other end of the buffer spring is connected to a slider. The slider is rotatably connected to a hinge rod through a pin, and one end of the hinge rod is rotatably connected to a contact plate through a pin.

[0008] As a further embodiment of this utility model: the side plate is located directly above the contact plate, and a rubber pad is provided above the contact plate; the slider is slidably connected to the slide rail.

[0009] As a further embodiment of this utility model: the vertical plate slides within the limiting plate, the top plate and the upper surface of the limiting plate are interlocked, and the guide groove is designed to be inclined.

[0010] As a further embodiment of this utility model: a connecting spring is sleeved on the guide post, one end of the connecting spring is connected to the forming plate, and the other end of the connecting spring is connected to the upper mold. Both the forming plate and the limiting plate are provided with a wear-resistant coating.

[0011] As a further embodiment of this utility model: the two ends of the threaded rod are provided with threads in opposite directions, the threaded sleeve is threadedly engaged with the threaded rod, the threaded rod is rotatably connected in the sliding groove, and two guide rods are connected in the sliding groove. The two guide rods are respectively arranged on both sides of the threaded rod, and the guide rods are slidably engaged with the sliding hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This environmentally friendly and wear-resistant stamping die is equipped with a motor, threaded rod, threaded sleeve, moving plate, push plate, guide groove, movable rod, vertical plate, and ejector plate. The operator starts the motor to rotate the threaded rod. The threaded engagement between the threaded sleeve and the threaded rod causes the two moving plates to drive the push plate to move in opposite directions along the threaded rod. At this time, the movable rod slides in the guide groove and is pushed by the inclined guide groove, causing the vertical plate and ejector plate to slide in the limiting plate. This causes the ejector plate to push out the formed workpiece, making it easier for the operator to pick up the workpiece and improve the efficiency of stamping.

[0014] 2. This environmentally friendly and wear-resistant stamping die, through the setting of side plates, contact plates, hinge rods, sliders, slide rails and buffer springs, when the upper die moves down along the guide post, the side plates will abut against the contact plates, thereby pushing the contact plates down. At this time, the two ends of the hinge rod will rotate, which will push the slider, causing the slider to slide along the slide rail and compress the buffer spring, thus buffering the contact and avoiding excessive contact impact that could damage the forming plate. The wear-resistant coating on the forming plate and the limiting plate can improve wear resistance, thereby reducing wear and avoiding excessive wear that leads to frequent replacement and waste.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: an environmentally friendly and wear-resistant stamping die, including a lower die base 1, a limiting plate 2 connected above the lower die base 1, a forming plate 3 connected to the lower die base 1 through the limiting plate 2, slide rails 4 connected to both sides of the limiting plate 2, buffer springs 19 sleeved at both ends of the slide rails 4, one end of the buffer spring 19 connected to the limiting plate 2, and the other end of the buffer spring 19 connected to a slider 20, the slider 20 being rotatably connected to a hinge rod 21 through a pin, one end of the hinge rod 21 being rotatably connected to a contact plate 22 through a pin, the hinge rod 21 pushes the slider 20 to compress the buffer spring 19, thereby buffering the downward movement of the upper die 17 and preventing the upper die 17 from directly contacting the forming plate 3 and causing damage.

[0022] A groove 5 is provided inside the lower mold base 1. A motor 6 is fixedly installed on one side of the lower mold base 1. The output shaft of the motor 6 is connected to a threaded rod 7. The two ends of the threaded rod 7 are provided with threads in opposite directions. The threaded sleeve 9 is threadedly engaged with the threaded rod 7. The threaded rod 7 is rotatably connected in the groove 5. Two guide rods 24 are connected in the groove 5. The two guide rods 24 are respectively located on both sides of the threaded rod 7. The guide rods 24 are slidably engaged with the sliding hole 10. When the threaded rod 7 rotates to move the moving plate 8, the moving plate 8 will slide along the guide rods 24, thereby guiding the moving plate 8 so that the moving plate 8 can move smoothly in the groove 5.

[0023] Two movable plates 8 are installed on the threaded rod 7. Threaded sleeves 9 are connected to the movable plates 8. Sliding holes 10 are opened on both sides of the threaded sleeves 9 on the movable plates 8. Push plates 11 are connected to both sides of the movable plates 8. Guide grooves 12 are opened on the push plates 11. Movable rods 13 are slidably connected in the guide grooves 12. Vertical plates 14 are connected to the movable rods 13. Ejector plates 15 are connected to the vertical plates 14. The vertical plates 14 slide within the limiting plate 2. The ejector plates 15 are fitted into the upper surface of the limiting plate 2. The guide grooves 12 are designed to be inclined. When the movable plates 8 move, the inclined guide grooves 12 can push the movable rods 13 upward, thereby causing the vertical plates 14 to slide within the limiting plate 2, allowing the ejector plates 15 to disengage from the limiting plate 2, thus ejecting the formed workpiece.

[0024] A guide post 16 is connected to the molding plate 3, and a connecting spring 23 is sleeved on the guide post 16. One end of the connecting spring 23 is connected to the molding plate 3, and the other end of the connecting spring 23 is connected to the upper mold 17. Both the molding plate 3 and the limiting plate 2 are provided with wear-resistant coatings. The wear-resistant coatings on the surfaces of the molding plate 3 and the limiting plate 2 can increase the wear resistance of the molding plate 3 and the limiting plate 2, thereby reducing wear and avoiding frequent breakage and waste.

[0025] An upper mold 17 is slidably mounted on the guide post 16. Side plates 18 are connected to both sides of the upper mold 17. The side plates 18 are positioned directly above the contact plate 22, and a rubber pad is provided above the contact plate 22. The slider 20 is slidably connected to the slide rail 4. The rubber pad on the contact plate 22 can buffer the contact between the side plate 18 and the contact plate 22, avoiding damage caused by excessive impact from direct contact.

[0026] The working principle of this utility model is as follows:

[0027] When the upper mold 17 moves down to press the workpiece, the side plate 18 pushes the contact plate 22 down, causing the hinge rod 21 to push the slider 20 to slide along the slide rail 4 and compress the buffer spring 19, thereby buffering the contact and avoiding excessive contact impact that could damage the forming plate 3. After the workpiece is formed, the motor 6 is started to rotate the threaded rod 7. The threaded sleeve 9 and the threaded rod 7 are engaged, allowing the two moving plates 8 to drive the push plate 11 to move in opposite directions along the threaded rod 7. This causes the movable rod 13 to slide in the guide groove 12 and be pushed by the inclined guide groove 12, causing the vertical plate 14 and the ejector plate 15 to slide in the limiting plate 2. This causes the ejector plate 15 to eject the formed workpiece so that the workers can easily pick it up.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
