As one method for the manufacture of plastic parts, injection
moulding has been well developed. An injection mould
assembly, as shown in Fig. 1, typically consists of a mouldbase,
runners, core and cavity, cooling channels, ejectors, and
other auxiliary components. Among these functional parts, the
core and cavity, which form the shape of the moulding, are
at the centre of a mould. An undercut is any portion of the
moulding that prevents it from being extracted from the
impression, along the parting direction. An undercut adjacent
to the cavity is usually referred to as an external undercut,
and one adjacent to the core as an internal undercut.
