AI Technical Summary
Existing injection molds for automotive lights are time-consuming during demolding and can easily cause scratches or damage to the workpiece, affecting quality.
The transmission system driven by an electric motor uses gears and racks to automate the movement of the upper mold, which in turn drives the power plate to slide upwards synchronously for rapid demolding, reducing manual operation.
It increases demolding speed, reduces the risk of workpiece damage, and improves demolding efficiency and energy utilization.
