| titleOfInvention | Optical grain forming die, die manufacturing method and optical grain forming method |
| abstract | The invention discloses an optical grain forming die, a die manufacturing method and an optical grain forming method, wherein the optical grain forming die comprises a cover plate, a grain plate and a bottom plate which are sequentially overlapped from top to bottom; the cover plate is detachably connected with the bottom plate so as to clamp the corrugated board; a positioning groove matched with the grain plate is formed in the upper part of the bottom plate; a through hole which penetrates through the cover plate from top to bottom is formed in the cover plate; the upper wall of the grain board is formed with optical concave-convex grains; the part of the corrugated board, which is formed with the optical concave-convex grains, and the through hole enclose a forming cavity with an upward opening. The invention can easily and conveniently replace the grain plate with different optical concave-convex grains into the optical grain forming die according to the optical grains to be formed, has the advantage of lower cost and is more suitable for industrial production. |
