道路标志界碑钢模具在工程中的定义为小型模具，而且需要的量不是很大，但是缺一不可的。在使用这种塑料模具的时候，还需要配套上使用平面振捣台，并且在模具的内部喷刷上润滑油，以增大更好的光滑性特点。该模具材料市场也得到迅速的发展，其在现实生活和生产中的应用比较广泛。道路标志界碑钢模具主要作用就是警示作用，防止施工人员挖断管道，所以每隔数十米或几米，就能看到一个直接插入地面的圆形标记。这些圆形标记虽然高出地面，但四周被设计成斜面状，而且位置比较合理，一般情况下不会对行人走路带来妨碍。因为这些圆形标记清晰而确切地标明地下管道的类别、走向等，再粗心的施工者也不会在如此鲜明的标记下乱挖乱掘，除非是故意破坏。

The steel mould of road sign boundary pillar is defined as small mould in engineering, and the quantity needed is not very large, but it is indispensable. When using this kind of plastic mold, we need to use a plane vibration table and spray lubricating oil on the inside of the mold to increase the smoothness. The mold material market has also been developed rapidly, which is widely used in real life and production. The main function of the steel mold of the road sign boundary pillar is to warn and prevent the construction personnel from digging the pipeline. Therefore, every tens of meters or several meters, you can see a circular mark directly inserted into the ground. Although these circular signs are higher than the ground, they are designed to be inclined around, and the location is relatively reasonable, which generally does not hinder the walking of pedestrians. Because these round marks clearly and accurately indicate the category, direction, etc. of underground pipelines, no matter how careless the constructors are, they will not dig or dig under such clear marks unless they are intentionally damaged.
