AI Technical Summary

Technical Problem

Existing injection molds suffer from problems during demolding, such as insufficient adaptability to complex structural models, easy deformation or damage of the model, low precision of pneumatic auxiliary systems, poor coordination of slider movement, and limited durability of mold positioning structures, resulting in high production costs and low efficiency.

Method used

The electric push rod drives the slider in conjunction with the ventilation component and the demolding component. High-pressure air is injected between the model and the mold to create a gap, and the demolding component is used to efficiently eject the model. The limiting pins and limiting holes ensure precise mold alignment.

Benefits of technology

It significantly reduces demolding resistance, improves demolding efficiency and mold integrity, ensures product quality, is suitable for a variety of complex injection molding scenarios, and has a compact structure and is easy to operate.
