[0019] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0020] It should be noted that, in the description of the present invention, terms such as "middle", "upper", "lower", "left", "right", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0021] See attached Figures 1 to 3The replaceable bottom switch sleeper mold provided in this embodiment includes a fixed end beam 1 and a tensioned end beam 2 that are relatively arranged. A side mold 3 is connected to both sides between the fixed end beam 1 and the tensioned end beam 2. The fixed end beam 1, the tensioned end beam 2 and the side mold 3 all adopt conventional technologies in the industry, which will not be repeated here. A partition 4 is arranged in the middle between the two side molds 3. The partition 4 is a full-length design so that the mold forms two full-length cavities. The mold is a double-row mold structure. The length of the mold shell is determined by taking the longest combination length as the shell length after optimizing the arrangement and combination of long and short sleepers according to the total number of sleepers of different models. The number of molds is determined by the number of optimized combinations of the total number of sleepers.

[0022] A bottom mold support plate 5 is provided on both sides of the bottom of each cavity, that is, the bottom mold support plate 5 is welded to the side mold 3 or the partition plate 4, and a shell side plate 6 is smoothly connected to the top of the bottom mold support plate 5. A through-length T-slot 7 open downward is provided at the bottom of the bottom mold support plate 5; a plurality of T-bolts (not shown) are inserted into the T-slot 7, and the T-bolts include a head and a rod, the head is clamped in the T-slot 7, and the rod extends out of the T-slot 7. A plurality of bottom mold connecting plates 8 are placed at the bottom of the cavity and below the bottom mold support plate 5, and a plurality of through holes 9 are provided on the bottom mold connecting plate 8, and the rod of the T-bolt passes through the corresponding through holes 9 and is locked by a nut 14 (not shown). Since the position of the T-bolt in the T-slot 7 is adjustable, the fixed position of the bottom mold connecting plate 8 is also adjustable. In other words, the position of the bottom mold connecting plate 8 can be freely adjusted along the length direction of the mold.

[0023] The bottom mold panel 10 is detachably connected to the upper middle part of the bottom mold connecting plate 8. Specifically, the two bottom mold supporting plates 5 corresponding to each cavity are relatively provided with step portions 11, the bottom mold panel 10 is clamped on the two step portions 11, and a plurality of screws 12 are welded below the bottom mold panel 10; the bottom mold connecting plate 8 is provided with through holes 13 corresponding to the screws 12, and the screws 12 pass through the through holes 13 and are locked by nuts 14. A limiting protrusion 15 is provided above the middle part of the bottom mold connecting plate 8. The bottom mold panel 10 is made of thick steel plate with a smoother surface, which is aligned with the edge and upper surface of the step portion 11, making the positioning more accurate and quick, and having strong durability.

[0024] like Figure 3 and 4 As shown, the position of the through hole 13 of the bottom mold connecting plate 8, that is, the position of the connecting screw 12 for the bottom mold panel 10, is provided with a limiting protrusion 15, which is used to limit the corresponding bottom mold panel 10, that is, it can be positioned in the up and down directions and the left and right directions, so that the installation position of the bottom mold panel 10 is more accurate. The bottom mold supporting plate 5 at other positions may not be provided with the limiting protrusion 15 and the through hole 13, such as Figure 5As shown. The positions of the bottom mold panel 10 and the bottom mold support plate 5 should avoid the position of the embedded iron seat. Multiple bottom mold connecting plates 8 are arranged at equal intervals along the length direction of the mold. And the spacing between two adjacent bottom mold connecting plates 8 is about 500mm.

[0025] The replaceable bottom mold panel 10, the shell side panel 6, and the bottom mold support plate 5 form a long trough structure, and are separated according to the type of switch sleeper by a through plate to form a casting space. The through plate structure is a conventional practice in the industry and will not be described in detail. The utility model only needs to process the bottom plate panels of different types of switch sleepers, which reduces the cost of mold investment and also speeds up the mold processing cycle.

[0026] The above are the preferred embodiments of the utility model and the technical principles used therein. For those skilled in the art, without departing from the spirit and scope of the utility model, any obvious changes such as equivalent transformation, simple replacement, etc. based on the technical solution of the utility model shall fall within the protection scope of the utility model.
