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構。也叫做線路下部結構。路基與橋梁、隧道相連，共同構成一條線路。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、箱子或結構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。模具鋼材應滿足強度、硬度、耐磨、耐熱、耐蝕等使用性能。同時還應具有良好的拋光性、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

塑料蓋板模具平常要怎么清洗呢?首先是模具表面灰塵的清掃:用干凈的抹布抹完之后,用手摸模具表面,如果感覺不到有灰塵的話,那么就是合格。沖孔部位的清掃:用錘子把孔內(nèi)的廢料還有滑料板上粘著的廢料和刃口部位切廢料的殘屑全部清除掉。有鍍層的模具,必須對模具的拉伸表面進行清掃,必須用手來確認表面是否光潔,生產(chǎn)時的一張材料必須用抹布抹干凈,生產(chǎn)后,必須給模具涂上少許的油。還有就是裝模前要對模具的上下表面進行清擦,保證模具安裝面和壓機工作臺面不受壓傷及模具在生產(chǎn)中上下安裝面的平行度。模具裝好后將模具打開,將模具各部分清擦干凈,特別是導向機構,對于表面件模具,其型面清擦干凈,以保證制件的質(zhì)量。
