[0002] Auto parts, also known as auto components, auto parts, and auto spare parts, refer to the components that make up the various units of the entire car and all consumable materials that serve the car. From the perspective of automotive products, all system components, system assemblies, components, parts and other related parts that make up the entire vehicle are called auto parts, including engine parts, transmission parts, brake parts, steering parts, running parts, electrical instrument parts, body and accessories, automotive interior and exterior decoration, etc. There are many varieties, which can be classified according to the purpose, production source, material, installation location, supply and marketing relationship and other aspects. In the field of auto parts manufacturing, stamping dies are key equipment used to stamp metal sheets. Their precision and stability directly affect the quality of parts and production efficiency. Traditional stamping dies mostly use fixed positioning structures during use, which are difficult to adapt to the processing needs of workpieces of different sizes or shapes. Adjustment is cumbersome and easily leads to positioning deviation, affecting stamping consistency. After stamping, the workpiece is prone to adhesion in the mold cavity and needs to be manually removed from the mold. Some workpieces are large in size and can easily cause people to slip and fall, resulting in bumps and damage. To this end, we propose a stamping die and stamping process for automotive parts. Summary of the Invention

There are two lubricating liquid tanks (45) and they are fixed respectively at the middle of the front and rear side surfaces of the bottom mold base (5). The top surface of the lubricating liquid tank (45) is equipped with a liquid pump (44). The liquid outlet pipe of the liquid pump (44) is connected to the liquid inlet of the atomizing nozzle (42). There are two fixing frames (43) and they are fixed respectively at the outer side surfaces of the two support plates (27). The inside of the fixing frame (43) is clamped with the atomizing nozzle (42). The bolt (41) passes through the through hole on the top surface of the fixing frame (43) and is threadedly installed with the screw hole on the top surface of the atomizing nozzle (42). The input end of the liquid pump (44) is electrically connected to the output end of the controller (16).

7. The automotive parts stamping die according to claim 1, characterized in that: It also includes a mounting groove (8), a locking rod (9), a mounting plate (10) and a handle (11), wherein the mounting grooves (8) are arranged in pairs on the front and rear sides of the bottom mold base (5) and the top mold base (6), and the mounting grooves (8) are correspondingly engaged with the mounting plates (10). The locking rod (9) on the inner side of the mounting plate (10) is correspondingly plugged into the through hole inside the mounting groove (8), and a handle (11) is installed on the surface of the mounting plate (10).

8. The automotive parts stamping die according to claim 1, characterized in that: It also includes a shielding plate (12), a T-shaped block (13) and a T-shaped slot (14), wherein the T-shaped slot (14) is provided on the surface of the bottom mold base (5), the T-shaped block (13) is fixed to the inner side surface of the shielding plate (12), and the T-shaped block (13) is slidably mounted on the T-shaped slot (14).

9. The automotive parts stamping die according to claim 6, characterized in that: It also includes a liquid level sensor (15), which is installed on the surface of the lubricating liquid tank (45), and the output end of the liquid level sensor (15) is electrically connected to the input end of the controller (16).

10. A stamping process for a stamping die for automobile parts, characterized in that: The following steps are involved: 1): Select a mold of appropriate specifications and insert it into the bottom mold base (5) and the top mold base (6) respectively, and insert the mounting plate (10) into the mounting groove (8) so that the locking rod (9) is inserted into the locking hole on the surface of the mold for locking installation; 2): Rotate the rotating wheel (218) to drive the screw (219) to rotate to adjust the position of the positioning frame (29), cooperate with the limit plate (215) that is engaged with the clamping frame (217) and the clamping groove (216) to automatically clamp and fix the material plate, start the external hydraulic press to drive the top mold base (6) to descend so that the pressing frame (21) presses the fixing seat (22), and cooperate with the roller (213) to slide on the wheel groove on the top surface of the inclined guide frame (214) to automatically expand the positioning frame (29) to prevent the material plate from being misplaced; 3): After the stamping is completed, when the top die base (6) rises, the motor (33) is started to drive the support plate (35) to rotate to the lower side of the top die base (6) to prevent it from falling and being damaged during the demoulding process. At the same time, the liquid pump (44) is started to spray the lubricant into the inside of the mold through the atomizing nozzle (42) to prevent the workpiece from sticking.
