1. Consider lateral die opening interval

General lateral mechanical mold opening interval is relatively small. Therefore, when selecting the parting surface, the direction of the length of the core pulling distance should be selected in the direction of the opening and closing of the front and back mold, and the short direction should be regarded as the side parting.

2. plastic injection mold parts are easy to process

When selecting the parting surface, the injection mold should be divided into parts that are easy to process to reduce the difficulty of machining.

3,.conducive to exhaust

When the parting surface is the primary exhaust, the parting surface should be planned at the end of the plastic activity to facilitate the exhaust.

4. R typing

For many products of plastic injection mold planning, there is a whole circle of R Angle at the parting surface. At this time, the parting must take into account the best parting of R, and the sharp side cannot be presented.
