fix-half subassembly are shown in Fig. 7(b). This assembly is
designed by the IMOLD system. Each plate of the mould base
is automatically positioned in the assembly. The standard parts
such as the locating ring and ejector are added to the assembly
automatically, and the pockets for these standard parts are also
created automatically.
     7. Conclusion
The proposed feature-based and object-oriented hierarchical
representation for injection mould assembly not only extends
the feature paradigm to the assembly design, but also encapsulates
operational functions and geometric constraints, such as
the degree of freedom, mating conditions, insertion and orientation
limits, etc. Because of the extension of the feature
paradigm to assembly design, the modifications, such as dimen-
sional changes of the assembled component can be made even
after the completion of the assembly process. The encapsulation
of assembly objects has the following two advantages: first,
because the mating conditions are encapsulated in the assembly
objects, automatic assembly design is easy to implement; secondly,
the encapsulated operational functions in the object
assembly automate the routine processes of assembly design,
such as pocketing and interference check. The proposed simplified
action analysis can substantially reduce the programming
effort needed for automatic checking for component interference
within a mould assembly.
