The cable tray mould is mainly used in other cable laying fields such as high-speed railway cement infrastructure construction, high-speed cement infrastructure and so on. As one of the basic links in the cement-based construction project of high-speed railway, the laying length of high-speed railway cable trough mold is 10000 kilometers. Generally speaking, the traditional railway cable tray mold has been designed with single U structure, and this cable tray mold is more innovative. Cable tray mold and concrete cable tray mold are white plastic molds with U-shaped appearance. They are commonly used in the production of cable tray. Cable tray mould now occupies an important position in the production of cable tray on high-speed railway and expressway. The specific component size of the cable tray plastic mold not only meets the use function, but also has a small height and width ratio, which reduces the size of the excavation pit in the construction process and greatly shortens the construction period and capital investment. The sizes and specifications of cement cable tray molds are different. Generally, the plastic molds of larger models of cable tray use ABS as the raw material, and the high-speed railway cable tray molds often add some patterns on the cover plate for decoration and anti-skid.
The standard basis for the description of common cable tray molds focuses on the mold specification and mold quality, because various data of the model of cable tray preform specified in the drawing need to be reflected in the mold manufacturing, so as to ensure the production capacity of cable tray plastic mold and cable tray. Starting from the prefabricated blocks of cable tray actually required, different materials are selected according to the specifications and manufacturing standards. The contents involved are not only in terms of mold specifications, but also include the cost of production mold, the time of production mold, whether the production mold meets the manufacturing requirements of prefabricated blocks, etc, These factors directly affect which specification of cable tray mould is selected for the project. In the process of using the cable tray mold, the technical requirements are relatively low. It can be completed only by pouring the mixed concrete into the mold. It should be noted that it should be poured at one time, otherwise the integrity of the product will be affected and separation is likely to occur. During pouring, the vibrating rod needs to be inserted into the concrete to prevent the honeycomb structure from affecting the service life. The surface of the product just made may not be so smooth and needs simple grinding.
