[0002] Auto parts are the components that make up a car and the products that serve it. There are many different types of auto parts. As people's living standards improve, their spending on cars is increasing, and the auto parts market is also growing. Auto parts are often formed using stamping dies during the manufacturing process.

[0003] At present, some sheet metal parts of automobile parts on the market require stamping equipment to stamp the sheet metal metal plates. Usually, the sheet metal metal plates are manually placed on the back of the stamping die to achieve the part stamping process. However, when the stamping die is pressed down, the operator's hand may be squeezed due to the operator's error, resulting in personal injury. At the same time, the die extrusion will cause a great impact force on the bottom module, which makes the bottom module easily damaged. Therefore, an automobile parts stamping die is proposed to solve the above problems. Utility Model Content

[0009] Preferably, the top mold groove is just embedded in the top of the bottom mold frame, so that the metal plate can be squeezed between the top mold groove and the bottom mold frame.

[0010] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects:

[0011] This automotive parts stamping die uses a lifting rod and a return spring to reduce the damage caused by the top die table to the bottom die table when it is pressed down, thereby increasing the service life of the top die table. At the same time, it uses an infrared sensor and a receiver to sense whether there is an obstacle between the infrared sensor and the receiver, thereby achieving a risk avoidance effect.

[0018] In the description of the utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc., should be understood in a broad sense. For example, "connected" can mean fixed connection, welding, riveting, bonding, etc., or detachable connection, threaded connection, key connection, pin connection, etc., or integral connection; it can be mechanical connection or electrical connection; it can be direct connection or indirect connection through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood by those skilled in the art in specific circumstances.

[0019] like Figure 1-3 As shown, the utility model proposes a stamping die for automobile parts, comprising a bottom plate 1 and a top plate 2, four support columns 3 are arranged at the four corners between the bottom plate 1 and the top plate 2, a cylinder 4 is installed on the top of the top plate 2, a bottom die table 6 is arranged on the top of the bottom plate 1, a bottom die frame 7 is arranged on the top of the bottom die table 6, a top die table 5 is arranged at the bottom of the top plate 2, a top die groove 14 is provided at the bottom of the top die table 5, four limiting columns 8 are provided between the top plate 2 and the bottom die table 6, a pressure groove 13 is provided at the bottom of the bottom plate 1, two rows of lifting rods 12 are provided inside the pressure groove 13, and the outer surfaces of the two rows of lifting rods 12 are both provided with reset springs 16, infrared sensors 9 are provided on the front and back of the top die table 5, and receivers 10 are provided on the front and back of the bottom die table 6.

[0020] It should be noted that the infrared sensor 9 and the receiver 10 are used to determine whether the operator's hand has not been pulled away from the top mold table 5 through an obstacle, so as to prevent the operator's hand from being damaged.

[0021] Specifically, the infrared sensor 9 scans the receiver 10 at the bottom to determine whether there is an obstacle between the infrared sensor 9 and the receiver 10, thereby achieving a risk avoidance effect.

[0022] In this embodiment, through holes for four limiting columns 8 to pass through are opened at the four corners of the top of the top mold platform 5, the output end of the cylinder 4 is connected to the top of the top mold platform 5, and a top mold groove 14 is opened at the bottom of the top mold platform 5.

[0023] It should be noted that the top mold groove 14 is exactly embedded in the top of the bottom mold frame 7, so that the metal plate is exactly located between the top mold groove 14 and the bottom mold frame 7 when being extruded.

[0024] In an optional embodiment, four limiting grooves 15 are further provided on the left and right sides of the pressure-bearing groove 13 , and four limiting blocks 11 are provided on the left and right sides of the bottom mold platform 6 , and the four limiting blocks 11 are clearance-matched with the four limiting grooves 15 .

[0025] It should be noted that the two rows of lifting rods 12 are connected to the bottom of the bottom mold platform 6 , and cooperate with the limiting blocks 11 and the limiting grooves 15 to enable the bottom mold platform 6 to move inside the pressure-bearing grooves 13 .

[0026] In an optional embodiment, a circular hole is opened on the top of the top plate 2 for the output end of the cylinder 4 to pass through, so that the output end of the cylinder 4 can pass through the top of the top plate 2 and be connected to the top of the top mold table 5. The cylinder 4 is fixed to the top of the top plate 2 by setting a fixed seat.

[0027] Specifically, when a stamping die is needed to stamp automobile parts, the metal plate can be placed between the top die table 5 and the bottom die table 6 through the equipment, and then the cylinder 4 is used to drive the top die table 5 under the restriction of the limit column 8, so that the top die groove 14 at the bottom of the top die table 5 cooperates with the bottom die frame 7 to extrude the metal plate. When the top die table 5 is extruded downward, the bottom die table 6 at the bottom will reduce the pressure through two rows of lifting rods 12 and the return spring 16, and at the same time cooperate with the limit groove 15 inside the pressure groove 13 and the limit block 11 to limit the bottom die table 6, thereby achieving the effect of alleviating the pressure exerted by the top die table 5 on the bottom die table 6.

[0028] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention.
