Description

Technical Field

[0002] Car hood, usually refers to the car engine cover or hood, formally known as the engine hood, is an important exterior body component that covers the car engine compartment. During the production process of the car hood, a stamping die will be used for stamping processing to stamp the metal material into a car hood or stamp the car hood into a specific shape. When the car hood is stamped on the stamping die, the locking mechanism inside the stamping die will be used to clamp and limit it to prevent the car hood from shifting during stamping and avoid stamping failure.

[0003] The existing locking mechanism is basically composed of two telescopic cylinders and a limit block. When the staff places the car hood on the stamping die, the two telescopic cylinders drive the two limit blocks to move relative to each other, completing the clamping and limiting of the car hood, and the stamping die can then be used for stamping processing. However, after the stamping is completed, the staff manually removes the car hood from the stamping die. However, after the car hood is in the stamping mechanism, part of the structure of the car hood will fit tightly with the stamping die under the stamping of the stamping die.
