Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to an automobile parts stamping die with an improved ejection mechanism. Background Art

[0002] Most auto parts are stamped parts, which are generally made by cold stamping with a stamping die. The stamping die generally includes an upper die and a lower die. The part to be stamped is placed on the lower die. The upper die moves downward under the action of a press. When the working parts on the upper die interact with the workpiece to be stamped on the lower die, the workpiece to be stamped is deformed by force and becomes the required auto part. Since auto parts are easily stuck in the molding cavity after being subjected to a large impact, and it is not convenient to remove them quickly, an ejection mechanism is usually set inside the mold to eject the auto parts. However, the ejection mechanism of the existing stamping die mostly ejects the auto parts through the elastic force of the spring. However, if the force of the spring on the auto part is less than the force of the molding cavity on the auto part, the auto part cannot be ejected, which affects the work efficiency.
