Abstract


WPC as a new environmentally friendly energy-saving materials , in recent years has been very rapid development. With WPC profiles in the construction and decoration industries more widely, for WPC extrusion technology requirements are also increasing. Rational design of extrusion die extrusion for improving production efficiency has a very important significance. Based on the traditional design method for automotive decorative profile extrusion die structure and size of the preliminary design . Considering the effect of die swell , tensile deformation effect, the cooling effect of the tripartite face extrusion die shrink the die size of the impact of their counterparts in die size design analysis . Design process found a lot of traditional design methods have shortcomings and defects , it is necessary WPC extrusion mold to optimize the design . Through the analysis of structural parameters of the extrusion die , extrusion die to determine two pairs of fluid flow within the greatest impact on the balance of the structural parameters : straight length and compression angle . In ANSYS finite element analysis software to optimize the experimental tool , the level of these two parameters to simulate the three orthogonal experiments , different structural parameters obtained in case of mold fluid velocity field and pressure field distribution . For multi- channel structure of the extrusion die to mold runner fluid flow velocity at the outlet of the mold flow balance and the largest drop as the optimization targets. Contours according to the speed and pressure contours , finishing the experimental data analysis . By analyzing the straight segment length and compression angle on the fluid flow balance and mold flow channel pressure drop , determine the final optimized structure parameters of the extrusion die . This paper draws some conclusions and methods to determine the length of the straight section and compression horn two parameters are balanced impact on liquidity and mold runner affect the relationship between the pressure drop graph for the actual manufacturing process tryout and repair mode pointed out the direction to reduce the extrusion die design cycle for conventional extrusion die design method has important guiding significance.
