hot-runner design, and introduced an approach of conceptual
information expressed by knowledge units (KU) and structure
units (SU) to establish a knowledge base (KB). Then it designed a
multi-cavity mold hot-runner structure based on knowledge
driven mechanism, and performed simulation analysis and
optimization for the design work. Therefore, based on knowledge
transfer, the informational integrated design of the multi-cavity
injection mold hot-runner was realized. 8511

I. INTRODUCTION
With advantages of shorter production cycle time, raw
material consumption saving, less waste products, improved
product quality, and application range expansion of plastic
injection molding, hot-runner is one of the key technology
during the eleventh Five-Year Plan [1]
.
In hot-runner product development field, many
companies have researched the technology, e.g. MOLD-
MASTERS of Canada, HUSKY, INCOE, DME, HASCO,
FASTHEAT of the USA, EWIKON, GUNTHER of Germany,
PLASTHING of the UK, THERMOPLY of Italy, SEIKI of
Japan, and YUDO of Korea. They have performed researches
on hot-runner technology, and developed products that have
been successfully applied in plastic injection molding. In
theoretic research area, R.Spina
[3]
has compared different hot-
runner systems, gate and product configurations, and
evaluated manufacturability and process feasibility of each
system through thermal stress and strain distribution, which
was studied by using finite element analysis. L.Kong,
J.Y.H.Fuh[4]
established a system for 3D plastic injection mold
design, in which the mold structure can be designed within an
software environment developed form 3D CAD. Ko-Ta
Chiang et al
[5]
suggested a method to efficiently optimize
machining parameters of thin-wall injection-molded part
through grey-fuzzy logic analysis. After establishing a
stochastic polynomial matrix model, Chi-Huang Lu et al
[6]
has
developed a corresponding thermocouple representation
system by establishing the model of random polynomial
matrix. Su Juanhua et al
[7]
have studied and discussed design
process and design approach of a specific plastic injection hot-
runner mold. Zhang Weizhong et al
[8]
researched the nozzle
that is one of the parts of a hot-runner system, and then did
detailed design and CAE analysis for it. These researches
greatly promoted plastic injection mold hot-runner design
from different angles. However, the design work involves
complicated knowledge about material, structure, mechanics
and machining, therefore, the integration of processes of
structure design, corresponding expressions solving, and
temperature field simulation analysis is required. Lacking of
the knowledge support or only focusing on unilateral research,
a complete design can hardly be done. For multi-cavity molds,
the number and the structure of cavity must be designed
according to quantity and specifications of the products since
inpidual design lacks of reusability thus resulting in low
efficiency.
Having researched and formalized expressions of the
knowledge about design process of multi-cavity injection
mold hot-runner, the author established a knowledge base of
hot-runner design, and integrated conceptual design, structure
design and assembly design for seriation design of multi-
cavity hot-runner structure. The author also performed
temperature control system design and temperature field
simulation analysis through the connection of structure
