Modern mold making
stamping die development history and status of technology

In
1953,
the
Changchun
First
Automobile
Works
in
China
for
the
first
time
established a die shop, the car plant in 1958 began manufacturing automotive panel
die. 60
years of the 20th century
began producing
fine blanking dies. Come a long
road of development, China has formed about 300 billion (not including Hong Kong,
Macao and Taiwan statistics.) Production capacity of various types of stamping dies.
Formed,
such
as
Ningbo
and
Zhejiang
HUANGYAN
region

village
Guangdong Corporation and some large rapid rise of township enterprises, K el o n,
M id e a, K on ka and other groups have established their own mold manufacturing
center;
joint
ventures
and
wholly
foreign-owned
the
mold
companies
now
have
thousands.
With
the
pace
with
international
standards
continues
to
accelerate,
increasing market competition, production and design of the mold has been growing
recognition that product quality, cost, and new product development capacities. Mold
manufacturing technology to measure a country's manufacturing sector has become an
important indicator of the level, and largely determine the survival space. At present,
China
stamping
die,
whether
in
quantity
or
in
quality,
technology
and
other
capabilities
have
made
significant
progress,
but
with
national
needs
and
the
world
advanced level, the gap is still great. In the international competition situation, I had
the mold industry has rapidly developed, many specialized research centers continue
to die set up, mold steel of the structure and made significant achievements, but there
is still a big gap. First, imports of high-tech mold most of the large precision molds,
mold and exports most of the lower middle and low-tech die, so high-tech high-grade
die stamping die market, the overall satisfaction rate is
lower than satisfaction rate,
which
mold
development
has
lagged
behind
the
production
of
stamping
parts,
and
low-technology market to meet the rate of middle and low die stamping die is higher
than the overall market to meet the rate; second is due to the price of the mold is much
lower than international market prices, has some competition force, so its prospects in
the
international
market;
third
in
recent
years,
Hong
Kong-and
Taiwan-owned,
foreign-funded
enterprises
in
China
developed
rapidly
in
a
large
number
of
these
enterprises stamping dies produced for own use no precise statistics, it is not included
in the figures being.






II. Modern mold manufacturing technology development






The
development
of
modern
technology
should
die
mold
products
to
meet
the

Urgent need to develop to meet this requirement as a number of


(1) to comprehensively promote universal DBD / DBM / DBE technology





Die DBD / DBM / DBE technology is the development direction of mold design
and manufacturing. With the computer software development and progress, universal
DBD / DBM / DBE technology, conditions are ripe, the businesses will increase DBD
/
DBM
technical
training
and
technical
service
efforts;
further
expand
the
scope
of


DBE
technology.
The
development
of
computers
and
networks
are
making
DBD
/
DBM / DBE technology trans-regional, cross- enterprise, campus-wide in the industry
as
possible
to
promote
and
achieve
re-integration
of
technical
resources
to
enable
virtual manufacturing possible.


(2) High-speed milling





The
development
of
foreign
high-speed
milling
process
in
recent
years,
significantly
improve
the
processing
efficiency,
and
to
get
a
high
surface
finish.
In
addition,
the
module
can
also
be
processed
with
high
hardness,
but
also
with
low
temperature
rise,
thermal
deformation
and
so
on.
High-speed
milling
technology,
automotive, home appliance manufacturing industry in the large cavity mold injected
new vitality. It currently has more agile, intelligent, integrated direction.


(3) die scanning and digitizing system





High-speed
scanner
provides
scanning
system
and
mold
from
the
model
or
in
kind
to
the
processing
of
the
scanned
model
of
the
desired
number
of
features
required, greatly reducing the manufacturing cycle in the development of mold. Some
quick
scan
system
can
be
quickly
installed
in
existing
CNC
milling
machine
and
machining center, for fast data acquisition, automatic generation of a variety of CNC
machining
process,
the
DBD
data
in
different
formats,
for
mold
manufacturing



(4) the degree of standardization to improve die





Degree of standardization of the mold is increasing, estimates that the current use
of standard mold coverage has reached about 30%. Developed countries is generally
about 80%.


(5) high-quality materials and advanced surface treatment technology





Application
of
high
quality
steel
and
the
corresponding
surface
treatment
technology to improve the life of the mold it is very necessary. Mold heat treatment
and
surface
treatment
can
fully
mold
steel
material
properties
play
a
key
part.
Direction of development of mold heat treatment is the use of vacuum heat treatment.
In
addition
to
the
mold
surface
should
improve
the
development
of
advanced
technologies such as laser surface treatment.

(6) Mold Polishing





Automation,
intelligent
mold
surface
quality
of
mold
life,
the
appearance
of
quality
parts
and
so
have
a
greater
impact
of
automation
and
intelligence
of
the
grinding and polishing methods replace the existing manual in order to improve the
quality of the mold surface is important trends.

(7) die development of automatic processing system





This
is
our
long-term
development
goals
mold
industry.
Automatic
mold
machine
processing
system
should
be
more
than
the
rational
combination;
with
accompanying
plate
positioning
fixture
or
positioning;
a
complete
equipment,
tool
CNC database; a complete CNC flexible synchronization system; a quality monitoring


and
control
system.
Of
course,
as
the
user
to
choose
the
right
equipment,
if
the
selection properly, not only can not make money but make the machine work into the
bitter situation.





III. Modern mold manufacturing technology trends





Die technology is
mainly towards the
future development
trend of
information
technology,
high-speed
high-precision
production
and
development.
Therefore,
the
design
technology,
the
development
focus
is
to
promote
DBD
/
DBE
/
DBM
technology,
and
continue
to
improve
efficiency,
especially
in
sheet
metal
forming
process
of
the
computer
simulation
analysis.
Die
DBD,
DBE
technology
should
be
declared
human,
integration,
intelligence
and
network
direction,
and
improve
the
mold
DBD,
DBM
system-specific
level.
To
improve
the
DBD,
DBE,
DBM
technology,
establish
a
complete
database
and
development
of
the
mold
expert
systems and improve software usability is very important.






From
the
processing
technology,
the
development
focused
on
high-speed
processing and precision machining. At present, the development of highly processed
high-speed
milling,
high
speed
polishing
and
high-speed
electronic
processing
and
rapid tooling technologies. At present, the development of precision machining parts
precision mold and the surface roughness of less 1μm Pa ≤ 0.1μm variety of precision
machining.





modern mold manufacturing





/CAE/CAM
computer-aided
design,
simulation,
manufacturing
integration
CAD
/
CAE
/
CAM
integration,
integration
technology
is
the
most
advanced
modern
mold
making
the
most
reasonable
mode
of
production.
Use
of
computer-aided design, support engineering and manufacturing systems, according to
the respective mold parts designed to prepare the NC machining of parts from design
to manufacturing process is an inevitable process, which is from CAD / CAE / CAM
system
carried
out,
The
processing
line
cable
input
directly
from
the
processing
machine, can be used in the preparation of procedures of processing the system analog
functions, will be part tool, tool holder, fixture, platform and tool speed, path, etc. are
displayed, to check the program prepared correctness. In short the CAD / CAE / CAM
system
development
and
simulation
of
processing
can
not
fully
understand
the
problems
identified,
resulting
in
processing
prior
to
prepare
the
complete
set
of
processing change work, which for the efficient and accurate processing of the mold
has a very important part .





2. Advanced equipment in the modern mold making role





The inevitable trend of modern mold making, machining is
possible to
replace
the manual process, especially now that CNC lathes, multi-axis machine tools, CNC
mold
engraving
machine,
EDM
machine,
CNC
precision
grinding
machines,
coordinate measuring machines, scanners and other modern equipment widely used in
factories,
but
most
of
these
devices
are
basically
the
application
of
the
procedures
used

with
the
provisions
of
