AI Technical Summary

Technical Problem

Existing precision injection molds have complex structures and are inconvenient to operate. One hand is needed to hold the movable plate to rotate the threaded rod, which affects the performance.

Method used

The worm gear structure is adopted, in which the worm drives the worm wheel and the threaded rod to rotate synchronously, thereby adjusting the position of the upper mold. The chuck plate drives the slider to move in the groove, and the position is identified by the scale lines. The worm gear is self-locking and does not require an additional limiting structure. At the same time, the guide seat and guide rod enhance the accuracy of movement, and the ball bearings and absorbent cotton ensure the lubrication effect.

Benefits of technology

The mold structure is simplified, the operation is convenient, the accuracy of upper mold position adjustment and lubrication effect are improved, and wear and lubricant contamination are reduced.
