Technical Field

[0001] The utility model relates to the technical field of stopper seat processing moulds, in particular to a mould used for processing a safety stopper seat. Background Art

[0002] In the field of railway transportation, especially in the manufacturing process of freight electric locomotives, the safety stop seat is a vital component. It is usually used to position and fix the freight car to ensure stability and safety during transportation. Since the eight-axle freight electric locomotive has a strong load-bearing capacity and a high running speed, the performance requirements of the safety stop seat are extremely high. Molds are needed when processing and producing the safety stop seat.

[0003] In the production process of the stop seat using mold processing, in order to speed up the cooling speed of the workpiece molding, a fan is installed to dissipate heat from the mold to achieve the effect of rapid cooling of the workpiece. However, the cooling effect of a single fan is limited, and the blown wind is uneven on the cooling surface of the mold, resulting in the workpiece molding speed is still slow, thereby reducing the production efficiency of the stop seat workpiece. For this reason, we propose a mold for the processing of safety stop seats. Utility Model Content
