ABSTRACT

Hot embossing and injection molding and injection compression molding of the mold are process by hot embossing and injection molding or injection compression molding the period. Mold insert can because of factor the and so on pressure influence, make to mold insert structure to damage, besides, test mold, if it will changes design of the mold inset microstructure, need to changes the part of mold insert. In designing the mold structure, In order to economize on replacement parts time and cost, we need change mold design mode, this paper to be about to design have three-dimensional microstructures for light guide plate, could in compliance with the designer to need, just only change ones mold insert or replacement insert mold of the insert board, but does not need to replacement entire mold. In mold insert microstructure processing part, could simultaneously separately to processing of mold insert, use different manufacture to processing mold insert of direction, such as LIGA-like process、 micromachining、metal etching, above-mentioned moulds made, though it is higher to make cost, but relative, henceforth it just only to changes mold insert part, can utilize the same pair of moulds, Separately carries on injection molding and injection compression molding and hot embossing, To advance mold benefit, and reduce the cost.

Keywords : light guide plate, metal etching, micromachining, injection molding, injection compression molding, hot embossing.
