Curved plate machining die

The utility model discloses a curved plate machining die which comprises a die body, a positioning frame and a composite laminate. The two sides of the mold body are each provided with a positioning frame, and the composite laminate is completely attached to the arc-shaped surface of the mold body. The mold main body is formed by splicing mold units in sequence; each mold unit comprises two rib plates and an arc-shaped panel unit fixed above the rib plates, and a complete cambered surface formed by splicing the mold units in sequence is consistent with the cambered surface parameter required by the design of the curved-surface cellular board. The die in a unit splicing form is convenient to transport and store and can be repeatedly used; due to the adoption of the density board, the weight is light and shaping is easy. 本实用新型公开了一种曲面板加工模具，包括模具主体、定位架和复合层板；模具主体的两侧分别设置一个定位架，复合层板与模具主体的弧形表面完全贴合。所述模具主体由模具单元按照顺序拼接而成；模具单元包括两块筋板和固定在筋板上方的弧形面板单元，模具单元按照顺序拼接后形成的完整弧面，与曲面蜂窝板设计要求的弧面参数一致。本实用新型的单元拼接形式的模具便于运输和存放，可重复使用；由于采用密度板制作，重
