The designing methods of injection mold of
the charger shell are mainly introduced
in this paper. First, the technological characteristics are analysed, including
material properties, forming characteristics and conditions, the process of the
structure, the forming equipment is
selected.Then the parting line is selected, the number of cavities is
determined.The specific introduction are made on gating system,
cooling system,Molding parts, Steering
mechanism, moulding mechanism, and spacer parting institutions.Then the
standard mould bases and mould materials are selected.and the technological
parameters of the forming equipment is checked. Finally, problems that may
emerge during the mold installation process are analysed and the appropriate
solutions are
provided. Threepence mould is used on the design of charger shell,that is pouring material and the plastic parts are ejected from different parting lines. there are four cavities in this mould,finally a stripper plate is used to push off the charger shells.
