Problems solved by technology

[0004] But above-mentioned existing full prism reflective material original mold making method still has following shortcoming: 1, what adopted in the manufacturing process is that the metal sheet that thickness is 0.05-0.5mm carries out overlapping splicing, and metal sheet has elastic shape, before processing In splicing and clamping, the complete fit between the metal sheets cannot be guaranteed and the straightness in the direction of the edge of the sheet cannot be guaranteed, resulting in a large error in straightness; 3. The processing of the full prism needs to process a slope along the direction of the edge of the sheet. Since the metal sheet used is thin and the edges are not obvious, the tool is It is difficult to locate the tool along the edge of the sheet, and the processing is easy to cause errors in dimensional accuracy

Embodiment Construction

[0021] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0022] The embodiment of the present invention discloses a thin-thick spacer lamination method for a microstructure mold, which includes the following steps:

[0023] Step (1), select a thick metal sheet with a thickness of 1mm-5mm and a thin metal sheet with a thickness of 0.05mm-0.5mm; superimpose the thick metal sheet and the thin metal sheet to form a metal splicing block, and the metal sheet is located in the adjacent thick metal sheet Between the sheets, at the same time, the thin metal sheet and the thick metal sheet on the left form a metal unit, and the metal units are arranged in an oblique dislocation, and the inclination angle of the metal unit relative to the horizontal plane is 35.25 degrees; figure 1 shown;

[0024] Step (2), flatten or grind the front and rear side planes of the metal splicing block; process the upper dislocation sur...

Abstract

The invention relates to the technical field of die manufacturing and provides a microstructure die manufacturing method with thick sheets and thin sheets being alternately stacked. By means of the microstructure die manufacturing method with the thick sheets and the thin sheets being alternately stacked, the straightness in the edge direction of metal sheets can be improved, so that the fit degree between the metal sheets can be improved, and the rigidity of the metal sheets can be improved; according to the processing manner, two-time inclined splicing machining is adopted, so that the toolsetting problem in the edge direction of the metal sheets is solved, and the machining difficulty is lowered.

Description

technical field [0001] The invention relates to the technical field of mold making, in particular to a thin-thick interval laminated manufacturing method for a microstructure mold. Background technique [0002] There are 3M companies in the United States, Japan, Tianjin University, etc. in the market for research on the production technology of full prism original molds. Most of the existing methods adopt the method of cutting grooves on the plane, and then dislocation assembly to form the original mold of the full prism. In this type of method, since the side of the sheet cannot be precisely processed, the precision of one of the three faces of the full prism is not enough, which affects the optical performance. [0003] In order to solve the aforementioned technical problems, the Chinese patent No. 2015107772604 discloses a method for making an original mold of a full prism reflective material. The four bundled sides are flattened or ground; ②Choose one of the four bundl...
