Numerical simulation of die-casting molding of main lens barrel and mold design
The main lens barrel is an important part of the optical instrument,the surface quality and matching accuracy of the workpiece are high,defects such as cold isolation and cracks are not allowed,and the tolerance of coaxiality and perpendicularity is 0.01 mm.The key to controlling product quality is the design of the mold pouring and overflow system and the setting of die casting parameters.The pouring and overflow system of annular feed is innovatively designed to optimize the die-casting process parameters.ProCAST software was used to simulate the metal solution filling and solidification process of the primary tube product.According to the structural characteristics of the product,the core-pulling mechanism in three directions is designed to ensure the smooth demoulding of the product.
