The mould design is an
intellectual work of realizing the idea of the mold so that the molded product
is within the desired specifications and the cost is within the requested
limit, and the items to be investigated can be classified into the following factors.
Functional design
- Maintaining the dimensions of
the molded product
- Investigations of the runner
and gate structure
- Investigations of the ejection
method
Shape design
- Three dimensional shape design
- External appearance quality
investigations (glossy surface, graining, etching, etc.)
- Investigation of shape
transfer, etc.
Strength design
- Cavity and core deformation,
breakage
- Deformation of the mold base,
etc.
Thermal design
- Investigation of the thermal
shrinkage with respect to the mold
- Investigation of the cooling
capacity of the molded product
- Investigation of the
temperature controlling means
Safety design
- Investigation of the hook bolt
strength
- Investigation of the mold
opening prevention structure, etc.
Maintenance design
- Investigation of the
maintenance parts structure
- Investigation of spare parts
- Investigation of ease of
disassembling and assembling
- Investigation of repeatability
Cost design
- Investigation of the mold cost
- Investigation of the molded
product cost
- Investigation of using standard
parts, etc.
Mold design is not merely
creating a space for producing the shape of the molded product, but it is very
important to carry out various studies from the above viewpoints.
