Automatic Injection Mold Unloading System

The function of this system is to remove the finished part from the cavity of the mold. A thread is molded on the outside of the part. This requires the part to be unscrewed in order to remove it from the mold.

There are four (4) parts to be unloaded at the same time. When the mold opens, the unloader descends into the cavity of the mold and locates over the hex portion of the part. Once engaged, the unloader will begin to unscrew the part from the cavity while moving away from the mold at a fixed rate equal to the pitch of the thread. Once the part is clear of the mold, it will fall into four (4) discrete chutes in order to segregate the parts by cavity mold number.
