A fast cooling sleeper production mold

Abstract

The invention discloses a fast cooling sleeper production mold, comprising a plurality of mold bodies that are fixedly connected to each other, and a cooling component, which is used for uniformly spraying water to cool the mold body; a cleaning component, which is used for Clean the concrete residue on the surface of the mold body and dry the water; the end die assembly, the end die assembly is located between two adjacent mold bodies, and is easy to install and disassemble, through the water hole on the mold and the nozzle pair The mold is cooled by spraying water, so that the mold can evenly and effectively complete the cooling of the entire mold in a short period of time, and the concrete powder crystals are cleaned by cleaning the components and the residual moisture on the surface of the rod mold is wiped clean, and then the end template is used to clean it. , to separate the end formwork from the concrete sleeper. This method is simple, convenient and quick to operate, and is more labor-saving.

Description

technical field [0001] The invention relates to the technical field of rail sleepers, in particular to a fast cooling rail sleeper production mold. Background technique [0002] Sleepers, also known as sleepers, are also a type of railway accessories. It's just that the material used is not only wood, so it is more scientific to call it a sleeper. At present, it is widely used as a concrete sleeper. [0003] The production of concrete sleepers is streamlined. After the pouring into the mold is completed, the sleeper is maintained in the steam curing tank, and then the sleeper is separated from the mold by the hook device. Finally, the template is cleaned and entered into the next round of production. The temperature of the final mold is generally above 60 °C, especially in summer, and the mold temperature should not exceed 35 °C when the next round of production is performed. The time required is too long, which affects the production efficiency of the assembly line. In ad...

AI Technical Summary

Problems solved by technology

[0003] The production of concrete sleepers adopts assembly line. After pouring into the mold, it is cured in a steam curing pool, and then the sleeper is separated from the mold by hook equipment. Finally, the formwork is cleaned and enters the next round of production. Due to the tight rhythm of assembly line production, demoulding The temperature of the finished mold is generally above 60°C, especially in summer, and the temperature of the mold must not exceed 35°C when the mold is in the next round of production. The traditional cooling method of the mold uses a fan to cool down, and the cooling efficiency is not high. The time required is too long, which affects the production efficiency of the assembly line, and due to the large area of ​​the formwork produced in batches on the assembly line, the cooling is uneven, and after the sleeper passes through the steam curing tank, due to the expansion of the concrete, the end molds at both ends will withstand the concrete sleeper. Difficult to separate the mold, often using a sledgehammer to knock the mold manually to remove the mold, resulting in mold deformation, concrete damage, and the sledgehammer is easy to hurt others. For this reason, we propose a fast cooling sleeper production mold
