Description

Technical Field

[0001] This utility model relates to the field of high-speed railway sleeper production technology, specifically a sleeper mold flipping and demolding machine. Background Technology

[0002] With the development of high-speed railway technology, various new types of ballastless tracks, which replace ballast track beds with concrete or asphalt mixtures, aim to improve track stability and smoothness, and significantly reduce maintenance workload. Ballastless tracks have been widely laid and applied on newly built high-speed railway trunk lines, achieving excellent technical and economic results.

[0003] Currently, the most commonly used type of precast concrete sleeper is the double-block concrete sleeper in the construction of ballastless high-speed railways. During the production of these sleepers, the molds after pouring the concrete need to be placed in a curing kiln for steam curing. After curing, the molds are rotated 180 degrees and placed on a demolding table. The double-block concrete sleeper is then removed by vibration. During this vibration demolding process, it often happens that one end of the sleeper has already been removed from the mold while the other end remains inside. This can lead to damage or breakage of the sleeper, resulting in defective products and a lower product qualification rate.
