模具零件裹面的組成
Composition of coating surface of mold parts
組成模具的零件形狀雖然各異，但構成每個零件的基本表面可概括為3種。
Although the shapes of the parts that make up the mold are different, the basic surfaces that make up each part can be summarized as three kinds.
(1)回轉面零件的外圓面、內圓面、JDG金屬穿線管 不銹鋼鏈板 隔離墩模具 檢查井鋼模具 流水槽模具 階梯護坡模具 護坡磚模具 遮板模具圓錐面等。
(1) Outer circular surface, inner circular surface, conical surface, etc. of revolving surface parts.
(2)平面板的表面和軸的端面等。
(2) The surface of the plane plate and the end face of the shaft, etc.
(3)曲面成形零件的二維曲面和三維曲面等。
(3) The two-dimensional surface and three-dimensional surface of surface forming parts.
模具零件成形的實質就是解決這3種基本表面的加工問題。對于回轉面和平面通常采用傳統的切削加工就可以成形，根據零件表面不同的精度要求和不同的材質可以選取不同的加工方案。
The essence of mold part forming is to solve the processing problems of these three basic surfaces. The rotary surface and plane can be formed by traditional machining. Different machining schemes can be selected according to different accuracy requirements and different materials of the part surface.
