Generally, the cover plate mold is a specially designed cover plate precast block built according to the roads in various regions, so there is no standard specification. Generally, the use of the road cover plate is concentrated on both sides. The cover plate mold, subgrade cover plate mold, and high-speed rail cover plate mold are mainly with gaps and holes. The introduction of the basic knowledge of the road cover plate mold is helpful to the statistics and use of all kinds of cover plate models. Because the number of plastic cover plate molds used on the road is not large every day, and it is very expensive to open the mold, so it is often replaced by similar models, which saves a lot of costs. The manufacture of road cover often has a certain road on the prefabricated block, and the emphasis is on the sign, so if there is a road sign or a word, basically new moulds should be customized. The road cover plate is mainly used for drainage, so the main feature of the mold is that it has both a gap and a hole
The selection of the cover plate mold material is also directly related to the mold size. Generally, plastic material is the main material, and special-shaped steel plate welding is used, which can meet the requirements of various models. When using the mold to make the prefabricated block, we should pay attention to the thin thickness, so when carrying or demoulding, we should handle it with care, so that the prefabricated block is not easy to be damaged. From the perspective of production materials, the side ditch cover plate mold is a kind of mold with plastic as the main part, steel plate as the auxiliary part, and less quantity production. The main characteristics of the mold are rich models. There are so many models and structures of side ditch cover plate that many molds need to be opened, which further increases the production cost of molds. If the number of purchased molds exceeds 200, Lichang mold will suggest to make plastic molds. If the number of purchased molds is less than 100, the cost of using steel formwork is lower. Side ditch cover plate is necessary for many projects, especially for drainage on both sides or in the middle.
