Plastic bucket mold cavity design and simulation processing
Abstract: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.
