Description

Technical Field

[0001] The utility model relates to the technical field of track fastener processing equipment, and more specifically, to a coated sand casting device for the production of track fasteners. Background Art

[0002] Coated sand casting is an advanced casting process, which has the advantages of high dimensional accuracy of castings, good surface quality, high production efficiency, etc. First, a corresponding model is made by coated sand, then the corresponding liquid is poured into the model, and then the coated sand is broken to obtain the required track fasteners.

[0003] In the prior art, when pouring into the coated sand model, generally, the coated sand model is first moved under the liquid outlet pipe, and then the liquid outlet pipe is opened, so that the liquid can enter the coated sand model. After pouring a certain amount, the liquid outlet pipe is closed, and then the coated sand model is transferred and processed such as cooling and mold splitting to obtain the corresponding track fasteners. However, there are some problems in its use. After the liquid outlet pipe is closed, there is still a certain amount of liquid remaining inside. If the coated sand model is directly moved away, it will cause a certain waste. And when the liquid outlet pipe is closed, it is impossible to continuously pour the track fasteners, which affects the work efficiency.

[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Summary of the Utility Model

[0023] The process of this device for casting track fasteners is as follows: Place the sand box 7 on the feeding conveyor device 9. Through the feeding conveyor device 9, the sand box 7 can be moved to a telescopic frame 6. By shortening this telescopic frame 6, the sand box 7 can be moved above the lifting frame 5, and the sand box 7 can be limited by the limiting frame 11. Then, through the lifting frame 5, the telescopic frame 6 and the sand box 7 can be pushed upward. Again, by extending the telescopic frame 6, the casting pipe 8 on the sand box 7 can be moved below the liquid outlet pipe 4. Open the liquid outlet pipe 4, and casting can be carried out into the sand box 7. At the same time, through the feeding conveyor device 9, the next sand box 7 can be moved to another telescopic frame 6. When the telescopic frame 6 is shortened and the first sand box 7 is almost finished casting, lower the first lifting frame 5 and raise the second lifting frame 5. Then, after the first sand box 7 is cast, extend the second telescopic frame 6, and move the casting pipe 8 on the first sand box 7 below the liquid outlet pipe 4 for casting. Through the feeding conveyor device 9, the next sand box 7 can be moved to the first telescopic frame 6 again, and the sand box 7 on the first telescopic frame 6 can be moved to the discharging conveyor device 10, and the material can be automatically changed.
