Abstract

The invention provides a preparation method of a hard die pressing prism pasting die. The method comprises the following steps that a convex die is cut on a flat substrate by using a diamond cutter under a set cutting condition to form a micro prism array, and pressure forming is performed to form the prism die. According to the prism manufactured by the hard die pressing, the phenomenon of imagedistortion of an existing soft die pressing prism can be solved, and meanwhile, the defect that a right angle of the existing prism cannot be effectively formed in a die processing course is overcome;and a microstructure is cut on one side of a plastic flat plate by using cutting tools such as diamond, and triangular microstructures with different widths and depths are cut by changing cutting parameters, so that the problem that a right angle cannot be formed can be effectively solved, and a degree of a prism prepared by the die is accurate.

Description

technical field technical field [0001] The invention relates to the technical field of mold processing, in particular to a method for preparing a triangular prism mold with hard mold pressing. Background technique [0002] Strabismus means that the two eyes cannot focus on the target at the same time when observing the target. It is a kind of eye disease that is often seen clinically. Strabismus is not only a disease that affects the appearance of the human body, but also has a very important impact on the patient's vision and binocular vision. The development of binocular vision in infants and young children is prone to problems, so this period is often a period of high incidence of strabismus, with an incidence rate of about 2%-3%. [0003] The current treatment methods for strabismus include: surgical treatment methods, non-surgical treatment methods and the combined use of the above two methods. However, surgery has always been regarded as an important means of impro...
