       旺滿模具系列；路基由填筑或開挖而形成的直接支承軌道的結(jié)構(gòu)。也叫做線路下部結(jié)構(gòu)。路基與橋梁、隧道相連，共同構(gòu)成一條線路。路基依其所處的地形條件不同，有兩種基本形式：路堤和路塹，俗稱填方和挖方。

The structure of directly supporting track formed by filling or excavation of subgrade. Also known as line substructure. The roadbed is connected with bridges and tunnels to form a line. There are two basic forms of subgrade according to its topographic conditi: embankment and cutting, commonly known as filling and excavation.

蓋板通俗意義上講是用來封閉或蓋住容器、箱子或結(jié)構(gòu)物截面的端部或頂部的蓋、罩或頂

In the popular sense, cover is used to close or cover the end or top of the section of a container, box or structure.

路基蓋板模具是由聚原料或者ABS樹脂（--丁二烯共聚物）經(jīng)過高溫融化注塑而成的方形塑料盒子。主要用于道路排水系統(tǒng)。

Roadbed cover die is a square plastic box made of polypropylene raw material or ABS resin (acrylonitrile-styrene-butadiene copolymer) melted and injected at high temperature. It is mainly used in road drainage system.

溝蓋板模具花紋圖案光蝕度性能 不少塑料制品為了美化,在其表面增添了花紋圖案,在皮革工業(yè)中,應(yīng)用大型皮紋壓花板,這都要求模具鋼具有較好的圖案光蝕性。模具鋼材應(yīng)滿足強度、硬度、耐磨、耐熱、耐蝕等使用性能。同時還應(yīng)具有良好的拋光性、尺寸穩(wěn)定性、易于氮化和熱處理變形小等工藝性能；良好的導熱性和小的線膨脹系數(shù)等物理性能等

溝蓋板模具企業(yè)設(shè)計和加工水平的提高,模具的制造正在從過去主要依靠鉗工的技藝轉(zhuǎn)變?yōu)橹饕揽考夹g(shù).這不僅是生產(chǎn)手段的轉(zhuǎn)變,也是生產(chǎn)方式的轉(zhuǎn)變和觀念的上升,這一趨勢使得模具的標準化程度不斷提高,模具精度越來越高,生產(chǎn)周期也越來越短,鉗工比例越來越低,終促進了模具工業(yè)整體水平不斷提高.近年來國家加大對基礎(chǔ)設(shè)施投資的力度和城市化的發(fā)展,國家對公用設(shè)施的投入極大,城市改造,對溝蓋板的需求量大增。
