井盖模具中，按照类型有圆形井盖模具和方形井盖模具。两种不同形状上会有什么区别？下面从几个角度来分析：
In the well cover mold, there are round well cover mold and square well cover mold according to the type. What's the difference between the two shapes? It is analyzed from several angles

1. 覆盖面积。要知道同等大小圆形的面积要比方形的大，而且圆形井盖使用上生产出的水泥井盖能更好的同路面相契合，造型上也会更加美观，所以常见道路上的井盖几乎都使用圆形模具制作而出的。
1. Coverage area. We should know that the area of the same size round is larger than that of the square, and the cement well cover produced by the use of the circular well cover can better match the road surface, and the shape will be more beautiful. Therefore, the well covers on the common roads are almost made by the circular mold.

2. 适用场合。模具一般生产的预制件都是用在了道路路面上，必须要有和路面同等的承受重力的能力，能支撑路面车辆行驶的重力。
2. Applicable occasions. Generally, the prefabricated parts produced by the mould are used on the road surface, which must have the same bearing capacity as the road surface and be able to support the gravity of road vehicles.
