AI Technical Summary

Technical Problem

With the increasing size of existing vertical plastic molding machines, the mold clamping mechanism lacks an effective locking mechanism, which may cause the upper mold plate to move uncontrollably downwards in case of emergencies, posing a safety hazard and affecting production safety.

Method used

A safety bar and a locking groove are installed on the upper template. The locking block is driven by a drive source to lock it in the locking groove. Combined with the guide block, this ensures that the upper template does not move downwards, thus improving safety.

Benefits of technology

The locking structure prevents the upper template from moving downwards, avoiding safety accidents and improving the safety of the equipment.
