[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) in cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the required parts. Stamping dies are widely used in various industries, especially in the manufacturing industries of automobiles, electrical appliances, furniture, and aircraft. Stamping dies play an important role in the manufacturing industry. They are of various types and widely used. Their manufacture and use need to follow certain processes and specifications to ensure that they can complete the stamping processing tasks efficiently and accurately.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 The utility model provides a technical solution: a stamping die for a rear shell of an automobile that is easy to pop up, comprising: a bottom plate 1, a support frame 2, a cylinder 3, an upper die 4, a convex column 5, a lower die 6, a positioning hole 7, a limit bar 8, a push plate 9, an electric telescopic rod 10, a connecting frame 11, a U-shaped frame 12, a moving frame 13, a screw 14, a motor 15, a limit slot 16, a support block 17 and a brush 18;

[0028] When using the easy-to-pop-up automobile rear housing stamping die, Figure 1 and Figure 2 As shown, a support block 17 is provided on the upper side of the bottom plate 1. When the lower mold 6 moves to the upper side of the support block 17, the support block 17 supports the lower mold 6 to prevent the upper mold 4 from directly pressing on the lower mold 6 when pressing downward, causing the moving frame 13 connected to the lower mold 6 to be bent;

[0029] like Figure 1 , Figure 2 and Figure 5As shown, a punched plate is placed on the upper side of the lower mold 6 so that it is located on the inner side of the two limit bars 8 to prevent the punched plate from tilting during the movement or punching process, resulting in the finished mold being unqualified. The moving frame 13 is threadedly connected to the screw rod 14, the left side of the screw rod 14 is fixedly connected to the output shaft of the motor 15, and the right side of the screw rod 14 is rotatably connected to the limit groove 16. When the motor 15 is started, the motor 15 will rotate with the screw rod 14. Since the moving frame 13 is slidably connected to the limit groove 16, the rotating screw rod 14 will cause the moving frame 13 to move in the limit groove 16, and the limit groove 16 will also support and limit the moving frame 13, so that the moving frame 13 is always in a vertical state, so that the lower side of the lower mold 6 and the upper side of the support block 17 are in a horizontal state, and then the lower mold 6 is moved to the upper side of the support block 17 through the U-shaped frame 12. When the positioning hole 7 on the lower mold 6 and the convex column 5 on the lower side of the upper mold 4 are in a vertical line, the motor 15 is turned off;

[0030] like Figure 3 As shown, during the leftward movement of the lower mold 6, the punched plate on the lower mold 6 first contacts the brush 18 on the lower side of the support frame 2, and the brush 18 cleans away impurities and dust on the punched plate, ensuring that the punched plate on the upper side of the lower mold 6 is clean and free of stains;

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, after the lower mold 6 moves to the bottom of the upper mold 4, the cylinder 3 under the support frame 2 is started, and the cylinder 3 will push the upper mold 4 to move downward. A convex column 5 is provided under the upper mold 4, and the convex column 5 corresponds to the positioning hole 7 on the lower mold 6 one by one, so as to prevent the center of the upper mold 4 and the center of the lower mold 6 from being on the same vertical line during the downward movement of the upper mold 4, resulting in the upper mold 4 continuing to move downward. The stamped plate is tilted, resulting in the stamped mold being unqualified. In addition, the side longitudinal section of the support block 17 is "U", which prevents the electric telescopic rod 10 and the connecting frame 11 from being aligned with the support The electric telescopic rod 10 is in direct contact with the block 17, causing the electric telescopic rod 10 to be damaged. When the stamping is completed, the mold needs to be ejected, the motor 15 is started, and the motor 15 is reversed to move the lower mold 6 to the left, so that the lower side of the lower mold 6 is away from the upper mold 4. Since the electric telescopic rod 10 is fixedly installed on the upper side of the connecting frame 11, the upper side of the electric telescopic rod 10 is fixedly connected to the push plate 9, and the push plate 9 is located inside the lower mold 6. The electric telescopic rod 10 will push the push plate 9 upward, so that the push plate 9 pushes out the stamped mold. There is no need for direct manual contact operation to ensure that the stamped mold is not worn after being taken out.
