Abstract

The invention discloses an optimization method for improving the injection molding precision of an optical element, which provides an injection molding process considering melt materials and mold core surface roughness on the premise that injection molding process parameters and the like are all optimal, selects different mold core surface roughness intervals according to different melt materials, and predicts the injection molding precision of the optical element on the basis of an existing ultra-precision machining quality prediction model. Compared with the extremely high quality requirement for the surface of the mold core in a traditional method, the optimization method for improving the injection molding precision of the optical element improves the molding precision of the optical element and reduces the surface roughness of the optical element on the basis of improving the machining efficiency of the mold core; and optimization of a micro injection molding process of the optical element and improvement of the optical performance of the element are facilitated.

Description

technical field [0001] The invention relates to the technical field of micro-injection molding, in particular to an optimization method for improving the injection precision of optical components. Background technique [0002] At present, micro-injection molding technology: through more advanced equipment, the process parameters, environmental variables and dimensional control are strictly controlled to process optical components with high surface quality (surface roughness, shape accuracy) and optical properties. The biggest feature is that the injection volume is small, the geometric dimensions of the mold core and the molded part are small, the parameter control of the injection molding process is relatively high, and the quality of the mold core is relatively high. [0003] Now the research on micro-injection mainly stays on the exploration of its injection molding process, such as injection speed, melt temperature, holding pressure, mold temperature, holding time, etc. ...
