Abstract


Pressing is the most important one of the molding method of automotive interior parts , has a broad market prospect . Due to the complexity of the molding process , the pressing process of automotive interior basically rely on trial . In this paper, a well-known automotive interior parts enterprises to introduce the car interior parts pressing production lines as the basis to solve product quality problems encountered in the actual production process for the purpose of computer-aided analysis software and numerical simulation software tools , simulation automotive interior parts of the pressing process and optimize the process parameters in the molding process on the basis of a detailed analysis of the simulation results . ( 1 ) through the analysis of the pressing process and product quality defects of automotive interior parts , determine the process parameters play a key role in the production process , the quality of the products . ( 2) the use of the general-purpose plastic molding software - POLYFLOW simulate automotive interior parts press molding the mold clamping process , to obtain a molding material in the mold cavity in the flow velocity distribution characteristics ; also obtained a molding material in the mold clamping process . the pressure in the distribution, to determine the molding pressure of the products required for molding . ( 3 ) the use of thermal analysis module of ANSYS to simulate the heating process, the pressing mold , mold temperature field in the overheating of the heating distribution , control the temperature of the heating time required to determine the reach of theory ; while for local temperature of the mold surface . too high due to product quality problems, the improved method . ( 4) using MATLAB software to simulate the curing process of the products , a detailed analysis of the distribution of the products during the curing process , the temperature and degree of cure ; investigated the impact of different process conditions on the products shaping Following comparative analysis found , an appropriate increase in mold a preheating temperature of the heating temperature and the molding material can be shortened molding time of the article , improving the mechanical properties of the article .
