AI Technical Summary

Problems solved by technology

[0005] But above-mentioned clamping structure of injection mold has the following defects: 1. The clamping structure adopts nylon shutter, which is easy to wear

2. It is impossible to realize the dynamic template and the static template to close the mold first

3. For injection molds with front mold sliders, the final closing of the dynamic and static templates will cause the front mold sliders to rub and burn, unable to seal the glue, and the product will have burrs
