At present ,injection molding is the
plastics mould that has being used most
extensively , it can mold the complex and high accurate plastic product. The
Subject is about the design of the plastic bucket process analysis. This mold considered the annual output, the
factory equipment and models the accuracy requirement, chooses a mold cavity
structure. The plastic bucket Tongbi thin, deep cavity, the core long, may be
caused by mold, and the core of different thickness of thin plastic uneven,
resulting in difficulties in forming, the high rejection rate. This is
particularly important for the thin-walled plastic bucket. In light of these
problems using a dynamic, scheduled to die-guided, guided sets of positioning.
In the barrels are high partly based on an independent cooling system, for
forming a barrel at the end of the module inserts, a circular cooling water,
the flow of imports and exports in the design of the fixed-board. Core Cooling
by the middle of a water main waterway, and then along the circumference are
divided into six sub-cloth effluent water, so that the entire core is fully
cooled, the whole mold of relatively uniform temperature field. Stripping
plastic parts used in air to the top.
Injection Mould CAD / CAM technology applications, to fundamentally
change the traditional mold plastic product development and processing, greatly
enhance the quality of the products and shorten the development cycle and
reduce the cost of production, astrong impetus to the mold industry. Some
large-scale commercialization of the CAD / CAM
software, such as Pro / Engineer, Unigraphics II, Cimatron, MoldFlow, have been
developed specifically for the injection mold design function modules for the
mold design provides a very convenient tool. Statistics show that there are
data, the use of CAD technology can shorten the time to die design 50 percent.
Europe and the United States
in some industrialized countries, CAD / CAM
die industry has become a universal application of the technology. In CAD
applications, has surpassed get rid drawing board, two-dimensional drawings of
the
initial stage.
Die Design in the use of 3D CAD software enterprises have been close to 90
percent. At present, there are many domestic enterprises began to die of CAD
software design. In the design process of formulating a reasonable programme to
meet the requirements of mass production. At the same time, has also prepared a
detailed document of the process to ensure the smooth processing and mould
products production. Through rational design, production and application of
molds to meet the requirements.
