Smooth out the corners and sharp turns in the mold design to avoid sudden changes in melt flow. After the part has cooled, the lifter pushes up at an angle, which removes the undercut section from the mold, and retracts from the undercut. A mold is made up of two halves that have a hollow space between them into which a melted material is injected. Sometimes there are some features on B Side of surface and they create interference in mold separation (features like snaps, dog house etc), they are in internal undercut region. The parting line location on the injection mold will have an effect on how the cavity and core (both halves of the injection mold) come together and seal. In plastic injection molding, core separates from cavity and is drawn in tooling direction. It is typically mounted on the moving half of the mold, and it helps to lift the mold off the stationary half of the mold during.
