Heavy duty truck parts press is one of the most important forming method of automobile interior parts, and has broad market prospect. Due to the complexity of the forming process and forming process of automotive interiors suppress research basically are relying on tests. In this paper, a well-known domestic auto interior decoration company relying on pressing production line for automotive trim pieces, to solve quality problems encountered in the production process for the purpose of software for computer-aided analysis and simulation software tools, simulate the forming process of automotive interiors, and based on the detailed analysis of the results of optimal process parameters in the forming process.
(L) by pressing technology for automotive interior parts and products quality defects analysis determines the production process of quality plays a key role in the process parameters.
(2) take advantage of GE Plastics prototyping software POLYFLOW automotive interior parts forming process simulation, access to the molding compound flow velocity distribution in the mold cavity; also got the clamping pressure distribution in the process of molding compound, determined the products required forming pressures.
(3) thermal analysis modules using ANSYS to simulate the heating process of pressing mold, won the die temperature distribution in heating overheating, determined the theory necessary to control the temperature of the heating time and die product quality problems caused by local surface temperature is too high, put forward the corresponding improvement methods.
(4) using the MATLAB software for numerical simulation of curing process of products, detailed analysis of product distribution of temperature and degree of cure in the curing process and investigated the effect of different conditions on the products, after analysis found that increasing die temperature and preheating temperature can shorten the molding products molding compound time, improving the mechanical properties of the products.
