Plastic mold production of general
machinery products in common, and also that its particularity. Compared with
the general machinery manufacturing, mold manufacturing is generally difficult,
especially precision molds. As a special technical equipment, mold production
and process are the characteristics of the following aspects.
1. Precision mold manufacturing, high
quality requirements, not only requires high precision, but also processing
good surface quality. In general, working part mold manufacturing tolerances
should be controlled within ± 0.011mm, and some even require within micron
range, surface defects after tooling requirements are very strict, and the
surface of the working portion of the roughness Ra <0.8 um.
2. shape of sophisticated mold part of the
work are generally two-dimensional or three-dimensional complex surface
(especially mold cavity), rather than the general machining of simple geometric
profile.
3. The mold as a single piece, many
varieties of each pair of mold can only produce Moi specific shape, size and
precision parts. In the manufacturing process as much as possible the use of
common tools, common measuring tools and instruments, as much as possible to
reduce the number of special tools. In the manufacturing process arrangement
requires relatively centralized process to ensure the quality and accuracy
mold, simplify management and reduce the process turnaround time.
The high hardness of the material is
actually a plastic mold machining tool, its high hardness, usually made of
hardened alloy tool steel or carbide and other materials, if manufactured using
conventional machining methods, often compare difficult, so mold processing
method different from the general machining.
5. Due to the short production cycle and
accelerate product replacement market competition becomes more intense,
requiring mold production cycles are getting shorter. Mold production
management, design and technological work should meet this requirement, to
improve the mold design, manufacturing and standardization, in order to shorten
the manufacturing cycle.
6. When a complete set of production parts
need more deputy mold, a mold before the products manufactured are mutually
implicated restrict Yi blank mold, mold parts, and only eventually qualified
parts, which was a series of mold considered qualified. In the production and
scheduling of the mold must take full account of this characteristic.
