Abstract

A method for preparing the template includes such steps as polishing the top surface of a plate, plating a hard film, and using circular ball to impact on the top surface to form multiple arc pits. A mother film with information pit pattern on its surface can be stuck on said template to decrease the contact area between them and the abrasion. It can also be directly used to form a light conducting plate with high brightness.

Description

technical field

[0001] The invention relates to a manufacturing method of a mold core, in particular to a manufacturing method of a mold core installed in an injection molding mold. Background technique

[0002] In the general industry, injection molding machines are used to form various thermoplastic products, among which there are sheet-type products used in optoelectronic products, such as optical discs, LCD light guide plates, etc., and the mold cores used to form these products are generally called It is a "mirror mold core". The following is an example of the mold core used for forming optical discs, such as figure 1 and figure 2 As shown, the general film core 11 is installed in an injection molding mold 12, and the mold 12 has a movable mold 123 and a fixed mold 121 corresponding up and down, and an upper mold core plate 125 fixed on the bottom surface of the movable mold 123, And a frame 122 arranged on the periphery. The mold core 11 is installed on the top sur...
