technology which in this design must grasp.This topic carries on the mold

core cavity modelling according to the handset battery cover, then carries

on the numerical control processing craft analysis, the selective treatment

method, the plan feeds the route, the definite cutting tool type qualified

cutting specifications, through the processing simulation, inspect have cut

with the collision. Processes the information according to the plastic mold

characteristic which the technological design and the computation module

produce, draws up the mold die space and the core structure, increases the

characteristic in this foundation, thus forms the mold the major parts - - -

die space, the core.In the design process, UG has provided the formidable

assembly modelling function.In the mold assembly modelling process,

the plastic product promotion is the group model, in the mold design

process, in assembly model all modules and the group model is related, if

the group model has made the revision, in assembly model all modules

also along with it automatic revision, the three dimensional assembly

merit also lies in from the three dimensional angle carries on the finite

element analysis to the entire assembly, may carry on the CAE

hydromechanics analysis on the computer.If appears the burn in the

backfill plastic process, feels suffocated sufficiently, does not fill and so

on the questions, may immediately carry on the revision to the mold

structure, avoids after the manufacture completing has the problem, thus

vanishes each kind of question in the design stage.
