Block-casting slide plate for railway turnouts
The invention relates to the technical field of railway accessories, and in particular relates to a block-casting slide plate for railway turnouts. The slide plate comprises a backing plate, a bedplate and an iron seat which are formed by investment casting, the bottom surface of the backing plate is a plane; the bedplate and the iron seat are arranged at the two ends, in the longitudinal direction, of the upper face of the backing plate correspondingly; a rail bearing groove used for accommodating the railway turnout stock rail is formed between the bedplate and the iron seat; the upper surface of the bedplate is a plane, a sealed cavity is formed between the bedplate and the backing plate, an opening located in the backing plate is formed in one side, located on the backing plate, of thecavity, and the area of the opening is not smaller than 1/3 of the projection area of the cavity on the horizontal plane. The ventilation opening with the large opening area is formed in the bottom of the backing plate, so that the cavity beneficial to shock absorption and deformation is formed in the lower portion of the bedplate, meanwhile, a casting mold is easier to machine, the forming effect is good, demolding is more convenient, and the machining and manufacturing efficiency of the slide plate is greatly improved.
本发明涉及铁路附件技术领域，具体公开了一种铁路道岔用整铸滑床板，包括通过融模铸造形成的垫板、台板和铁座，所述垫板的底面为平面，所述垫板上面纵向方向的两端分别设置有所述台板和所述铁座，所述台板和所述铁座之间形成用于容纳所述铁路道岔基本轨的承轨槽，所述台板的上面为平面，所述台板和所述垫板的之间具备密封空腔，所述空腔位于所述垫板一侧设置有位于所述垫板上的开口，所述开口的面积不小于所述空腔在水平面投影面积的1/3。本发明通过在垫板底部设置开口面积较大的通气口，使得在台板下部形成利于减震和形变的空腔的同时，铸模更容易加工，成型效果好，脱模更加便利，大大提高了滑床板的加工制造效率。
