1.1 Precision Mold temperature control

In general precision injection molding of parts, control mold temperature is to increase

productivity. However mold temperature control for precision injection molding of great
impact, it affects parts of the contraction, shape, crystallization, such as stress, hot and
cold circuit design mold temperature distribution at the request reasonable, precise control
accuracy, a die temperature of the best and Lengshuiji control. Mold temperature control
and cooling time on the products and their impact on performance of the following factors:

1.2 Precision Die Design and Manufacture

Die design is good or bad is to ensure the dimensional accuracy of plastic parts premise,
in order to enhance the accuracy of precision injection mold, in the process of designing a
computer-aided analysis is necessary, especially for gating system and the flow of
heat-conditioning systems mold temperature distribution the analysis. Applications should
be as much as possible the use of simulation software and close to the actual loading
conditions to melt in the mold simulation analysis in the pouring, cooling, and other
non-steady-state process.

Die manufacturing quality assurance plastic parts Size is the key to accuracy, precision
die is the main characteristic of the manufacturing and assembly operations in addition to
polishing, are no manual processing. Die general machining and manual processing ratio
is about 6:4 to 7:3, and the machining precision molds and manual processing ratio of 9:1.

Die materials and heat treatment is the protection of precision molds in the molding
process, the die temperature in the state, which even the mould parts tempered by low
temperature, high temperature melt production and will repeat parts tempering
而使
lower
hardness, Consideration should also be given retained austenite caused by the volume
expansion. Therefore general tempering temperature should be at least molding
processing, more than double the die temperature and low-temperature processing is
carried out properly in order to eliminate residual austenite.

On the high-precision products for Molding precision parts, assembly accumulated
precision die in the direction of the accuracy of the sub-surface as well as the parallel
degree should achieve micron level. Mold should have sufficient strength, stiffness and
abrasion resistance, in the injection molding deformation under the pressure of hard wear.
To achieve the above processing can be three-dimensional precision machining centers,
CNC machine tool and application of CAD / CAM / CAE and other new technologies.
