AI Technical Summary

Technical Problem

Traditional hard drive casing stamping dies present inconveniences during material cutting, especially when the casing surface is uneven, has oil stains, or air holes. Insufficient vacuum suction force can cause the casing to fall off, increasing the frequency of manual adjustments and reducing production efficiency.

Method used

The system employs a combination of ejection and pushing mechanisms. An electric push rod drives the movable box and lifting block, while the inclined groove and sliding column work together to push the placement plate out of the hard drive housing. A spring and sleeve work together to ensure smooth lifting and resetting. The push plate then pushes the housing onto the conveyor belt.

Benefits of technology

This improves the stability of hard drive casing transfer, reduces frequent manual adjustments due to unstable adsorption, and enhances production efficiency and equipment operational stability.

Abstract

The utility model relates to the related technical field of stamping machining, in particular to a hard disk shell stamping die convenient to discharge, which comprises a machining table, an ejection mechanism is arranged on the top wall of the machining table, and pushing mechanisms are arranged on two sides of the bottom wall of the machining table. The ejection mechanism and the pushing mechanism are matched for operation, the movable box is pushed through the first electric push rod, the inclined groove is matched with the sliding column, the lifting block and the placing plate are driven to eject out a stamped hard disk shell, then the stamped hard disk shell is pushed to the conveying belt through the push plate, and in the ejection process, a spring and a sleeve prevent the placing plate from rising too fast to impact a stamped part; and the placing plate is assisted to stably fall back during subsequent resetting, so that the problem of grabbing failure caused by poor surface condition of the shell is fundamentally avoided, the transferring stability of the hard disk shell in the production process is greatly improved, and compared with an adsorption mode, frequent manual adjustment caused by unstable adsorption is reduced, and the production efficiency is improved.
